Description

Sitz für ein Fahrzeug Seat for a vehicle
Die Erfindung betrifft einen Sitz für ein Fahrzeug nach dem Oberbegriff des Schutzanspruchs 1 .The invention relates to a seat for a vehicle according to the preamble of claim 1.
Sitze dieser Art werden in alle Arten von Fahrzeugen zu Lande, zu Wasser oder in der Luft eingebaut. Jeder Sitz weist eine Rückenlehne und ein Sitzelement auf und zur Erhöhung der Sicherheit können die Personen auf dem Sitz mittels eines Sicherheitsgurts, der im Fahrzeug befestigt ist, gesichert werden. Dieser Sicherheitsgurt hält die Fahrzeuginsassen im Falle eines Unfalles auf dem Sitz zurück und verhindert so in bekannter Art und Weise schwere Verletzungen. Außerdem ist in dem Fahrzeug ein Sensor zur Messung des dynamischen Fahrzustands, insbesondere ein Beschleunigungssensor, vorgesehen. Mit derartigen Sensoren können Fahrzustände, wie sie für verschiedene Arten von Unfällen typisch sind, erkannt werden. Solche Sensoren werden beispielsweise zur Auslösung von konventionellen Airbags eingesetzt.Seats of this type are installed in all types of vehicles on land, on water or in the air. Each seat has a backrest and a seat element and, for increased safety, the people can be secured on the seat by means of a seat belt which is fastened in the vehicle. This seat belt keeps the vehicle occupants on the seat in the event of an accident and thus prevents serious injuries in a known manner. In addition, a sensor for measuring the dynamic driving state, in particular an acceleration sensor, is provided in the vehicle. With such sensors, driving conditions that are typical for different types of accidents can be detected. Such sensors are used, for example, to trigger conventional airbags.
Fahrzeugsitze dieser Art müssen gleichzeitig hohe Anforderungen an die Sicherheit als auch an den Sitzkomfort erfüllen. Sowohl die Sicherheit des Sitzes als auch dessen Sitzkomfort werden wesentlich durch die Neigung und Ausformung der Sitzfläche und der Rückenlehne des Sitzes beeinflußt. Zur Erhöhung des Komforts sind deshalb Sitze bekannt, deren Sitzfläche und Rückenlehne in vielfältiger Weise verstellbar sind, um an die individuellen Bedürfnisse der Fahrzeuginsassen angepaßt werden zu können.Vehicle seats of this type have to meet high safety and comfort requirements at the same time. Both security the seat as well as its seating comfort are significantly influenced by the inclination and shape of the seat and the backrest of the seat. To increase comfort, seats are therefore known whose seat and backrest can be adjusted in many ways in order to be able to be adapted to the individual needs of the vehicle occupants.
Das Maß der Sicherheit eines Sitzes wird im wesentlichen u.a. dadurch bestimmt, ob der sogenannte ,,"Submarining"-Effekt wirkungsvoll verhindert werden kann. Mit dem „Submarining"-Effekt wird das Durchrut- sehen unter dem Beckengurt eines mit einem Sicherheitsgurt angeschnallten Fahrzeuginsassen bezeichnet. Dieser Vorgang kann zur Strangulierung des Insassen oder zu ernsthaften Bauch-, Becken- und Beinverletzungen führen. Der „Submarining"-Effekt kann dadurch ausgeschlossen werden, daß die Neigung der Sitzfläche und/oder der Rücken- lehne in einem definierten Winkel in der Art einer Rampe angeordnet werden, so daß ein Durchrutschen der Insassen verhindert wird.The degree of safety of a seat is essentially determines whether the so-called "submarining" effect can be effectively prevented. The "submarining" effect is used to refer to the slipping through under the lap belt of a vehicle occupant wearing a seat belt. This process can lead to strangulation of the occupant or to serious abdominal, pelvic and leg injuries. The "submarining" effect can result be excluded that the inclination of the seat and / or the backrest are arranged at a defined angle in the manner of a ramp, so that slipping of the occupants is prevented.
Nachteilig an den bekannten Sitzen ist es, daß durch die vielfältigen individuellen Einstellungen des Sitzes eine optimale Neigung der Sitzfläche oder der Rückenlehne zur Verhinderung des „Submarining"-Effekts ausgeschlossen wird. Im Ergebnis stellen die bekannten Fahrzeugsitze einen Kompromiß zwischen optimaler Sicherheit und Sitzkomfort dar.A disadvantage of the known seats is that an optimal inclination of the seat surface or the backrest to prevent the "submarining" effect is ruled out by the various individual settings of the seat. As a result, the known vehicle seats represent a compromise between optimal safety and seating comfort.
Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Sitz zu liefern, der einen hohen Sitzkomfort bietet und gleichzeitig ein verbessertes Sicherheitsniveau gewährleistet.The object of the present invention is to provide a generic seat which offers a high level of seating comfort and at the same time ensures an improved level of safety.
Diese Aufgabe wird durch einen Sitz nach der Lehre des Schutzanspruchs 1 gelöst.This object is achieved by a seat according to the teaching of protection claim 1.
Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche. Erfindungsgemäß ist am und/oder im Sitz zumindest ein Stellelement vorgesehen, durch das die Neigung der Sitzfläche und/oder der Rückenlehne zumindest Bereichsweise innerhalb sehr kurzer Zeit in Abhängigkeit vom durch den Sensor gemessenen dynamischen Fahrzustand des Fahrzeugs verstellbar ist. Mit anderen Worten bedeutet dies, daß der Sitz bei einem normalen Fahrzustand des Fahrzeuges individuell an die Bedürfnisse des Insassen angepaßt werden kann, um einen optimalen Sitzkomfort zu gewährleisten. Sobald der Sensor einen untypischen dynamischen Fahrzustand des Fahrzeuges mißt, beispielsweise im Falle eines Schleuderns oder Aufpralles auf ein Hindernis, wird das Stellelement ausgelöst und dadurch die Neigung und/oder die Ausformung der Sitzfläche und/oder der Rückenlehne so verstellt, daß insbesondere der „Submarining"-Effekt ausgeschlossen wird. Außerdem können die Füße des Insassen im Moment eines Unfalles von den Pedalen abgehoben werden, um Verletzungen in diesem Bereich zu verringern.Preferred embodiments of the invention are the subject of the dependent claims. According to the invention, at least one adjusting element is provided on and / or in the seat, by means of which the inclination of the seat surface and / or the backrest can be adjusted, at least in regions, within a very short time, depending on the dynamic driving state of the vehicle measured by the sensor. In other words, this means that the seat can be individually adapted to the needs of the occupant in a normal driving state of the vehicle in order to ensure optimum seating comfort. As soon as the sensor measures an atypical dynamic driving state of the vehicle, for example in the event of a skid or collision with an obstacle, the actuating element is triggered and the inclination and / or the shape of the seat surface and / or the backrest are adjusted so that in particular the “submarining "Effect is excluded. In addition, the occupant's feet can be lifted off the pedals in the event of an accident to reduce injuries in this area.
Nach einer bevorzugten Ausführungsform der Erfindung ist das Stellelement in der Art eines Airbags ausgebildet. Derartige Airbags sind an sich bekannt und können innerhalb kürzester Verzögerungszeiten ausgelöst werden. Als Sensor zur Auslösung des Airbags können die gleichen Sensoren eingesetzt werden, mit denen auch andere Airbags im Fahrzeug ausgelöst werden.According to a preferred embodiment of the invention, the actuating element is designed in the manner of an airbag. Airbags of this type are known per se and can be deployed within the shortest delay times. The same sensors can be used as the sensor for triggering the airbag, with which other airbags in the vehicle are also triggered.
Das Stellelement kann erfindungsgemäß auch in der Art eines pyrotech- nisch, pneumatisch, hydraulisch, chemisch, elektrisch oder mechanisch angetriebenen Linear-Aktuators und/oder Zirkular-Aktuators ausgebildet sein. Die unterschiedlichen Antriebsarten können dabei auch kombiniert werden. Beispielsweise kann eine vorgespannte Feder oder ein Pneumatikzylinder durch den Sensor ausgelöst werden und mittels einer mechanischen Übersetzung auf den Verstellmechanismus des Sitzes wirken.According to the invention, the actuating element can also be designed in the manner of a pyrotechnically, pneumatically, hydraulically, chemically, electrically or mechanically driven linear actuator and / or circular actuator. The different types of drives can also be combined. For example, a preloaded spring or a pneumatic cylinder can be triggered by the sensor and act on the adjustment mechanism of the seat by means of a mechanical translation.
Besonders vorteilhaft ist es, wenn das Stellelement in der Art eines expandierbaren Formelements ausgebildet ist, das mit einem reaktiven und expandierbaren chemischen Werkstoff gefüllt ist, der eine elastisch aushärtende Verbindung bildet, die insbesondere energieverzehrende Eigenschaften aufweist. In der Funktion ist ein derartiges Stellelement mit einem Airbag vergleichbar, wobei im Falle eines Unfalles j edoch kein Gas, sondern der chemische Werkstoff unter Bildung einer elastisch aushärtenden Verbindung expandiert, so daß die Form des Formelements dauerhaft erhalten bleibt und nicht, wie bei einem Airbag, zusammenfallen kann. Weist der Werkstoff zusätzlich energieverzehrende Eigenschaften auf, können Verletzungen durch starke Beschleunigungen zu- sätzlich reduziert werden.It is particularly advantageous if the actuating element is designed in the manner of an expandable molded element that is equipped with a reactive one and is filled with expandable chemical material that forms an elastically hardening compound that has, in particular, energy-consuming properties. The function of such an actuating element is comparable to that of an airbag, but in the event of an accident, however, no gas, but rather the chemical material expands to form an elastically hardening compound, so that the shape of the molding element is retained permanently and not, as in the case of an airbag , can collapse. If the material also has energy-consuming properties, injuries caused by strong accelerations can be further reduced.
Für die Anordnung des Stellelements in und/oder am Sitz gibt es erfindungsgemäß die unterschiedlichsten Möglichkeiten. Nach einer bevorzugten Ausführungsform weist der Sitz unterhalb der Sitzfläche des Sitzelements eine Bespannung und/oder ein Polsterelement auf und das Stellelement ist außermittig, insbesondere im Bereich der vorderen und/oder seitlichen Kanten unterhalb des Polsterelements, angeordnet. Handelt es sich bei dem Stellelement beispielsweise um einen Airbag, wird das Polsterelement nach der Auslösung des Airbags an der entsprechenden Kante nach oben gedrückt und bildet dadurch die gewünschte rampenartig geneigte Sitzfläche aus, die ein Durchrutschen des Fahrzeuginsassen verhindert.According to the invention, there are various possibilities for the arrangement of the control element in and / or on the seat. According to a preferred embodiment, the seat has a covering and / or a cushion element underneath the seat surface of the seat element and the adjusting element is arranged off-center, in particular in the region of the front and / or lateral edges below the cushion element. If the control element is, for example, an airbag, the cushion element is pressed upwards on the corresponding edge after the airbag has been deployed, thereby forming the desired ramp-like seat which prevents the vehicle occupant from slipping.
Bei einer Vielzahl von Sitzkonstruktionen ist eine im wesentlichen steife Sitzschale vorgesehen, die zumeist durch darüber angeordnete Polsterelemente abgepolstert ist. Nach einer weiteren erfindungsgemäßen Ausfüh- rungsform ist das Stellelement außermittig, insbesondere zwischen der vorderen und/oder einer der seitlichen Kanten der Sitzschale und einem starr mit der Karosserie verbundenen Bauteil, unterhalb der Sitzschale angeordnet. Dies ist insbesondere dann vorteilhaft, wenn das Stellelement nicht in der Art eines Airbags sondern in der Art eines Linear- oder Zirkular-Aktuators ausgebildet ist. Sobald das Stellelement durch den Sensor ausgelöst wird, drückt es die steife Sitzschale in den entsprechenden Bereich nach oben oder unten, so daß sich die Sitzfläche dementsprechend neigt. Durch die Sitzschale kann die Stellbewegung des Stellelements großflächig verteilt werden.In the case of a large number of seat constructions, an essentially rigid seat shell is provided, which is usually cushioned by cushion elements arranged above it. According to a further embodiment according to the invention, the adjusting element is arranged off-center, in particular between the front and / or one of the lateral edges of the seat shell and a component rigidly connected to the body, below the seat shell. This is particularly advantageous if the actuating element is not designed in the manner of an airbag but in the manner of a linear or circular actuator. As soon as the control element by Sensor is triggered, it pushes the rigid seat shell up or down in the corresponding area, so that the seat inclines accordingly. The actuating movement of the actuating element can be distributed over a large area through the seat shell.
Grundsätzlich kann die Sitzschale in an sich beliebiger Weise gestaltet sein. Besonders vorteilhaft ist es, wenn die Sitzschale zumindest zwei j eweils im wesentlichen steife Bereiche aufweist, die gelenkig miteinander verbunden sind. Das Stellelement wirkt dann nur auf einem Teil der Sitzschale, so daß durch relativ kleine Stellbewegungen große Änderun- gen des Neigungswinkels in diesem Bereich bewirkbar sind. Zur Verbindung der beiden Bereiche der Sitzschale kann beispielsweise ein Folienscharnier eingesetzt werden.Basically, the seat shell can be designed in any way. It is particularly advantageous if the seat shell has at least two regions which are each essentially rigid and are connected to one another in an articulated manner. The actuating element then acts only on part of the seat shell, so that large changes in the angle of inclination can be brought about in this area by relatively small adjusting movements. For example, a film hinge can be used to connect the two areas of the seat shell.
Eine weitere vorteilhafte Möglichkeit, die Neigung der Sitzfläche und/oder der Rückenlehne verstellen zu können, ergibt sich, wenn der Sitz zumindest teilweise parallel und/oder quer zur Längsachse des Fahrzeugs schwenkbar auf der Karosserie gelagert ist und die Stellung des schwenkbaren Teils des Sitzes durch Ansteuerung des Stellelements verstellbar ist. Mit anderen Worten bedeutet dies, daß ein Teil des Sitzes relativ zur Karosserie verschwenkt werden kann und die entsprechende Schwenkbewegung durch das Stellelement bewirkbar ist. Im Falle eines Unfalles und der daraus folgenden Auslösung des Stellelements wird der . verschwenkbare Teil des Sitzes so verstellt, daß ein Durchrutschen der Fahrzeuginsassen unter dem Sicherheitsgurt hindurch ausgeschlossen wird. Besonders vorteilhaft ist es, wenn der verschwenkbare Teil des Sitzes sowohl das Sitzelement als auch die Rückenlehne umfaßt, da dadurch im Falle eines Unfalles im wesentlichen der ganze Körper des Fahrzeuginsassen bewegt werden kann.A further advantageous possibility of being able to adjust the inclination of the seat surface and / or the backrest is obtained if the seat is at least partially pivotably mounted on the body and / or transversely to the longitudinal axis of the vehicle and the position of the pivotable part of the seat is determined by Control of the control element is adjustable. In other words, this means that part of the seat can be pivoted relative to the body and the corresponding pivoting movement can be effected by the adjusting element. In the event of an accident and the resulting actuation of the control element, the. pivotable part of the seat adjusted so that slipping of the vehicle occupants under the seat belt is excluded. It is particularly advantageous if the pivotable part of the seat comprises both the seat element and the backrest, since in the event of an accident this essentially allows the entire body of the vehicle occupant to be moved.
Um eine differenzierte Betätigung des Stellelements in Abhängigkeit der zum Auslösezeitpunkt individuell vorhandenen Sitzposition zu ermögli- chen ist es vorteilhaft, wenn die Stellbewegung des Stellelements in Abhängigkeit von der aktuellen Lage der verschiedenen Bauteile des Sitzes steuerbar ist.In order to enable a differentiated actuation of the actuating element depending on the individual sitting position at the time of triggering, it is advantageous if the actuating movement of the actuating element in Depending on the current position of the various components of the seat is controllable.
Das höchste Sicherheitsniveau zur Verhinderung des „Submarining"- Effekts wird erreicht, wenn der Sitz einen definierten Neigungsverlauf der unterschiedlichen Kontaktflächen zwischen Sitz und Fahrzeuginsassen aufweist. Dieser Neigungsverlauf ist im wesentlichen unabhängig von den subjektiven Komfortanforderungen der unterschiedlichen Fahrzeuginsassen, die bei der Einstellung des Sitzes zur Herstellung des optimalen Komforts Berücksichtigung finden. Zur optimalen Verhinde- rung des „Submarining"-Effekts ist es deshalb vorteilhaft, wenn dieThe highest level of safety to prevent the "submarining" effect is achieved if the seat has a defined inclination profile for the different contact surfaces between the seat and the vehicle occupant. This inclination profile is essentially independent of the subjective comfort requirements of the different vehicle occupants, which are important when adjusting the seat Production of the optimal comfort must be taken into account. In order to optimally prevent the "submarining" effect, it is therefore advantageous if the
Sitzfläche und/oder die Rückenlehne nach Auslösung des Stellelements einen definierten Neigungsverlauf aufweist.Seat and / or the backrest has a defined inclination course after triggering the control element.
Erfindungsgemäß müssen verschiedene Teile des Sitzes in ihrer Neigung verstellbar sein. Die Verstellung der entsprechenden Teile ist jedoch nur in außergewöhnlichen Fahrsituationen, insbesondere bei Unfällen, notwendig. Um eine ungewollte Verstellung der beweglichen Teile des Sitzes während des Normalbetriebes auszuschließen, ist es vorteilhaft, wenn die Lage der Teile des Sitzes, an denen das Stellelement zur Verstellung der Neigung der Sitzfläche und/oder der Rückenlehne zum Eingriff bringbar ist, durch zumindest ein Verbindungselement sicherbar ist, wobei dasAccording to the invention, different parts of the seat must be adjustable in their inclination. The adjustment of the corresponding parts is only necessary in exceptional driving situations, especially in the event of an accident. In order to rule out an unwanted adjustment of the movable parts of the seat during normal operation, it is advantageous if the position of the parts of the seat on which the adjusting element for adjusting the inclination of the seat surface and / or the backrest can be brought into engagement by at least one connecting element is securable, which
Verbindungselement eine Sollbruchstelle aufweist. Beispielsweise kann :. ein schwenkbarer Sitz mit entsprechend gestalteten Laschen an der Karosserie befestigt werden, wobei die Laschen bei Auslösung des Stellelements an Sollbruchstellen aufbrechen und dadurch die Verstellung des Sitzes ermöglichen. Im Ergebnis wird das Stellelement im Normalbetrieb von einem Hauptteil der mechanischen Belastung befreit, so daß es entsprechend schwächer dimensioniert werden kann. Außerdem werden unerwünschte Vibrationen und Knarrgeräusche verhindert.Connecting element has a predetermined breaking point. For example :. a swiveling seat with appropriately designed tabs are attached to the body, the tabs breaking open at predetermined breaking points when the actuating element is triggered, thereby enabling the seat to be adjusted. As a result, the control element is freed from a major part of the mechanical load during normal operation, so that it can be dimensioned correspondingly weaker. It also prevents unwanted vibrations and creaking noises.
Besonders vorteilhaft ist es, wenn am Sitz eine Arretiervorrichtung vorgesehen ist, durch die der verstellbare Teil des Sitzes nach der Ver- Stellung durch das Stellelement befestigbar ist. Nach der Stellbewegung wird der Sitz in seiner Endstellung durch die Arretiervorrichtung dauerhaft gesichert.It is particularly advantageous if a locking device is provided on the seat, by means of which the adjustable part of the seat after the locking Position is attachable by the actuator. After the adjustment movement, the seat is permanently secured in its end position by the locking device.
Selbstverständlich kann der erfindungsgemäße Sitz auch in der Art einer Sitzbank mit Sitzplätzen für mehrere Personen ausgebildet sein, so daß auch Personen auf dem Rücksitz eines Fahrzeugs optimal geschützt werden.Of course, the seat according to the invention can also be designed in the manner of a bench with seats for several people, so that people in the back seat of a vehicle are also optimally protected.
Nachfolgend wird der erfindungsgemäße Sitz anhand lediglich bevorzugte Ausführungsformen darstellender Zeichnungen näher erläutert. Es zeigt:The seat according to the invention is explained in more detail below with the aid of drawings showing only preferred embodiments. It shows:

Fig. 8 den Sitz gemäß Fig. 7 im Querschnitt entlang der Schnittlinie I-I; Fig. 9 eine siebente Ausführungsform eines erfindungsgemäßen Sitzes in Ansicht von oben:8 shows the seat according to FIG. 7 in cross section along the section line II; 9 shows a seventh embodiment of a seat according to the invention in a view from above:
Fig. 10 den Sitz gemäß Fig. 9 im Querschnitt entlang der Schnittlinie II-II.Fig. 10 the seat of FIG. 9 in cross section along the section line II-II.
Fig. 1 zeigt eine erste Ausführungsform 1 eines erfindungsgemäßen Sitzes mit einer Rückenlehne 2 und einem Sitzelement 3, wobei das Sitzelement 3 aus einem Polsterelement 4, einer Sitzschale 5, einem Sitzrahmen 6, mehreren Sitzfüßen 7 und einer Verstellschiene 8 aufgebaut ist. Die Oberseite des Sitzelements 3 wird von der Sitzfläche 9 gebildet.1 shows a first embodiment 1 of a seat according to the invention with a backrest 2 and a seat element 3, the seat element 3 being constructed from a cushion element 4, a seat shell 5, a seat frame 6, a plurality of seat feet 7 and an adjustment rail 8. The top of the seat element 3 is formed by the seat 9.
Im Bereich der vorderen Kante des Polsterelements 4 ist zwischen dem Polsterelement 4 und der Sitzschale 5 ein als Airbag 10 ausgebildetes Stellelement zur Verstellung der Neigung der Sitzfläche 9 angeordnet. Im Normalbetrieb ist der Airbag 10 zusammengefaltet, so daß sich der Sitz 1 in seiner Funktion, insbesondere in seiner Einstellbarkeit zur individuellen Anpassung der verschiedenen Sitzflächen an die verschiedenen Fahrzeuginsassen, nicht von einem konventionellen Sitz unterscheidet.In the area of the front edge of the upholstery element 4, between the upholstery element 4 and the seat shell 5, an adjusting element designed as an airbag 10 is arranged for adjusting the inclination of the seat surface 9. In normal operation, the airbag 10 is folded up so that the function of the seat 1, in particular its adjustability for the individual adaptation of the various seating surfaces to the various vehicle occupants, does not differ from that of a conventional seat.
Fig. 2 zeigt den Sitz 1 nach der Auslösung des Airbags 10 durch einen nicht dargestellten Beschleunigungssensor im Falle eines Unfalles. Man erkennt, daß der Airbag 10 durch Gasexpansion eine Volumenvergröße- . rung erfahren hat, so daß die Sitzfläche 9 im vorderen Bereich 1 1 eine sehr viel größere Neigung aufweist als im Normalbetrieb. Die dadurch entstehende Rampe wirkt dem „Submarining"-Effekt, bei dem die Gefahr des Durchrutschens der Fahrzeuginsassen unter dem Sicherheitsgurt hindurch besteht, entgegen. Nach dem Unfall muß der Airbag 10 zur Herstellung des Normalzustandes des Sitzes 1 ausgetauscht werden.2 shows the seat 1 after the airbag 10 has been triggered by an acceleration sensor (not shown) in the event of an accident. It can be seen that the airbag 10 increases in volume due to gas expansion. tion has experienced so that the seat 9 in the front region 1 1 has a much greater inclination than in normal operation. The resulting ramp counteracts the "submarining" effect, in which there is a risk of the vehicle occupants slipping under the seat belt. After the accident, the airbag 10 must be replaced to restore the normal state of the seat 1.
Fig. 3 zeigt eine weitere Ausführungsform 12 eines erfindungsgemäßen Sitzes, bei dem das Stellelement zur Verstellung der Neigung der Sitzfläche in der Art eines beispielsweise pneumatisch angetriebenen Linear- Aktuators 13 ausgebildet ist. Der Linear- Aktuator 13 ist zwischen dem feststehenden Sitzfuß 14 und der vorderen Kante der Sitzschale 15 angeordnet. Die Sitzschale 15 weist einen vorderen Teil 16 und einen hinteren Teil 17 auf, die durch das Foliengelenk 1 8 miteinander verbun- den sind.Fig. 3 shows a further embodiment 12 of a seat according to the invention, in which the adjusting element for adjusting the inclination of the seat surface in the manner of, for example, a pneumatically driven linear Actuator 13 is formed. The linear actuator 13 is arranged between the fixed seat base 14 and the front edge of the seat shell 15. The seat shell 15 has a front part 16 and a rear part 17, which are connected to one another by the film joint 18.
In Abhängigkeit von der aktuellen Einstellung des Sitzes 12 kann die Schubstange 19 nach oben und unten verfahren werden, so daß der vordere Teil 16 der Sitzschale 15 entsprechend weit angehoben wird und die Sitzfläche 20 nach Auslösung des Linear- Aktuators 13 eine definierte Neigung aufweist.Depending on the current setting of the seat 12, the push rod 19 can be moved up and down, so that the front part 16 of the seat shell 15 is raised accordingly and the seat surface 20 has a defined inclination after the linear actuator 13 has been triggered.
Fig. 4 zeigt eine Ausführungsform 21 eines erfindungsgemäßen Sitzes, dessen Funktion im wesentlichen der Ausführungsform 12 entspricht. Zur Anhebung des vorderen Teils 16 der Sitzschale 15 wird bei dieser Ausführungsform ein als Airbag 22 ausgestaltetes Stellelement eingesetzt.FIG. 4 shows an embodiment 21 of a seat according to the invention, the function of which essentially corresponds to embodiment 12. In this embodiment, an actuating element designed as an airbag 22 is used to raise the front part 16 of the seat shell 15.
Fig. 5 zeigt eine Aus führungs form 23 eines erfindungsgemäßen Sitzes, bei der das Stellelement 24 beispielsweise in der Art eines vorgespannten Federzylinders ausgestaltet sein kann, der auf der Unterseite der Sitzschale 25 befestigt ist. Sobald das Stellelement 24 durch den Beschleunigungssensor ausgelöst wird, zieht sich die vorgespannte Feder zusammen, wodurch die Sitzschale 25 in ihrer Ausformung derart verändert wird, daß die Sitzfläche 26 eine konkave Wölbung erhält, die dem „Submarining"-Effekt entgegenwirkt.5 shows an embodiment 23 of a seat according to the invention, in which the actuating element 24 can be configured, for example, in the manner of a prestressed spring cylinder which is fastened on the underside of the seat shell 25. As soon as the actuating element 24 is triggered by the acceleration sensor, the prestressed spring contracts, as a result of which the shape of the seat shell 25 is changed such that the seat surface 26 is given a concave curvature which counteracts the “submarining” effect.
Fig. 6 zeigt eine Ausführungsform 27 eines erfindungsgemäßen Sitzes, wobei der Rahmen 28 des Sitzes mit der daran befestigten Rückenlehne 29 auf den hinteren Sitzfüßen 30 schwenkbar gelagert ist. Zwischen den vorderen Sitzfüßen 31 und dem Sitzrahmen 28 ist ein beispielsweise hydraulisch angetriebener Linear-Aktuator 32 angeordnet, dessen Schubstange 33 entsprechend einem Sensorsignal, beispielsweise eines Beschleunigungssensors, ausfahrbar ist. Beispielsweise im Falle eines Unfalles wird die Schubstange 33 voll ausgefahren, so daß die auf dem Sitz befindliche Person zusammen mit dem Sitz nach hinten gekippt wird und dadurch ein Durchrutschen unter dem Sicherheitsgurt ausschließbar ist.6 shows an embodiment 27 of a seat according to the invention, the frame 28 of the seat with the backrest 29 attached to it being pivotably mounted on the rear seat feet 30. A, for example, hydraulically driven linear actuator 32 is arranged between the front seat feet 31 and the seat frame 28, the push rod 33 of which can be extended in accordance with a sensor signal, for example an acceleration sensor. For example in the case of a Accidentally, the push rod 33 is fully extended so that the person on the seat is tilted together with the seat to the rear, thereby preventing slipping under the seat belt.
Fig. 7 zeigt eine Ausführungsform 34 eines erfindungsgemäßen Sitzes in Ansicht von oben. In die seitlichen Kanten des Sitzpolsters 35 sind zwei Airbags 36 und 37 eingearbeitet. Im Falle eines Seitencrashs können die Airbags 36 und 37 ausgelöst werden, um einen seitlichen Versatz der Person auf der Sitzfläche zu verhindern.7 shows an embodiment 34 of a seat according to the invention in a view from above. Two airbags 36 and 37 are incorporated into the lateral edges of the seat cushion 35. In the event of a side crash, the airbags 36 and 37 can be deployed to prevent the person from shifting sideways on the seat.
Fig. 8 zeigt die Ausführungsform 34 im Querschnitt entlang der Schnittlinie I-I. Man erkennt in Fig. 8, angedeutet durch gestrichelte Linien, die Verformung des Sitzpolsters 35 auf der rechten Seite nach Auslösung des Airbags 37.8 shows the embodiment 34 in cross section along the section line I-I. 8, indicated by dashed lines, shows the deformation of the seat cushion 35 on the right side after the airbag 37 has been deployed.
Die in Fig. 9 dargestellte Ausführungsform 38 eines erfindungsgemäßen Sitzes ermöglicht wie die Ausführungsform 34 eine seitliche Anhebung der Sitzfläche im Falle eines Seitencrashs. Dazu sind unterhalb der Sitzschale 39 die beiden Airbags 40 und 41 angeordnet.The embodiment 38 of a seat according to the invention shown in FIG. 9, like the embodiment 34, enables the seat surface to be raised laterally in the event of a side crash. For this purpose, the two airbags 40 and 41 are arranged below the seat shell 39.
Wie aus Fig. 10 erkennbar, kann die Sitzschale 39 nach Auslösen des Airbags 40 seitlich angehoben werden, um die Neigung der Sitzfläche entsprechend zu verstellen. Gleiches gilt entsprechend für den Airbag 41 , falls der Aufprall des Seitencrash von der anderen Seite erfolgt. Die Anhebung der Sitzschale 39 kann alternativ dazu auch durch einen Linear-Aktuator erfolgen. As can be seen from FIG. 10, the seat shell 39 can be raised laterally after the airbag 40 has been deployed in order to adjust the inclination of the seat surface accordingly. The same applies accordingly to the airbag 41 if the side crash occurs from the other side. Alternatively, the seat shell 39 can also be raised by a linear actuator.
