Description
Verstellbarer Fahrzeugsitz Adjustable vehicle seat
Zusatz zu Patent ..... (Patentanmeldung P 29 33 093.6-21) Die Erfindung betrifft einen Fahrzeugsitz, der die Merkmale des Oberbegriffs des Anspruches 1 aufweist.Addition to patent ..... (patent application P 29 33 093.6-21) The invention relates to a vehicle seat that has the features of the preamble of claim 1 having.
Bei dem im Hauptpatent beschriebenen Fahrzeugsitz dieser Art wird mit Hilfe eines Endschalters bei einer Verstellung eine Kollision mit einem Hindernis selbsttätig verhindert. Beispielsweise schaltet der Endschalter bei einer Absenkung der Vorderkante des Sitzteils den diese Verstellbewegung bewirkenden Motor ab, ehe der Sitzteil vorne gegen ein sich unter dem Sitzteil befindendes Hindernis stößt. Der Endschalter veranlaßt sogar in diesem Falle eine geringe RG « ewegung, wenn der zugeordnete Steuerschalter wieder in seine Ausgangsstellung zurückkehrt, damit nicht eine eventuelle Anhebung der.Hinterkante des Sitzteils mittels eines anderen Antriebsmotors zu einer Kollision des Sitzteils mit dem genannten Hindernis führen kann. Hält jedoch die Bedienungsperson den Steuerschalter des erstgenannten Antriebsmotors im betätigten Zustand, dann kann die genannte geringe Rückführungsbewegung nicht erfolgen.In the vehicle seat of this type described in the main patent a collision with an obstacle with the help of a limit switch during an adjustment prevented automatically. For example, the limit switch switches when there is a drop the front edge of the seat part from the motor causing this adjustment movement before the front of the seat part hits an obstacle located under the seat part. Even in this case, the limit switch causes a slight RG movement, if the assigned control switch returns to its original position, so that not a possible lifting of the rear edge of the seat part by means of another drive motor to a collision of the seat part with the said Obstacle can lead. However, if the operator holds the control switch of the former Drive motor in the actuated state, then said small return movement not done.
Dies kann zu einer Kollision führen, wenn die Bedienungsperson gleichzeitig eine andere Verstellbewegung bewirkt, also beispielsweise gleichzeitig zwei Steuerschalter betätigt.This can lead to a collision if the operator is at the same time causes another adjustment movement, for example two control switches at the same time actuated.
Der Erfindung liegt die Aufgabe zugrunde, den Fahrzeugsitz gemäß dem Hauptpatent dahingehend zu verbessern, daß auch dann eine Kollision des Sitzes mit einem Hindernis verhindert wird, wenn die Bedienungsperson länger als zur Ausführung der Verstellbewegung notwendig die Steuerschalter betätigt.The invention is based on the object of the vehicle seat according to the Main patent to improve so that even then a collision of the seat with an obstacle is prevented if the operator takes longer than to execute the control switch is actuated necessary for the adjustment movement.
Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1.This object is achieved with the features of claim 1.
Die Ausbildung des Endschalters als zweipoligen Drehrichtungsumkehrschalter führt nämlich dazu, daß dann, wenn der Sitz sich einem Hindernis so weit genähert Rat, daß der Endschalter anspricht, eine Drehrichtungsumkehr des Åntriabsmotors bewirkt wird, unabhängig davon, ob die Bedienungsperson den zugeordneten Steuerschalter beim Ansprechen des Endschalters freigibt oder weiterhin betätigt hält. Gibt die Bedienungsperson den zugeordneten Steuerschalter während der durch die Umschaltung der Drehrichtung des Antriebsmotors bewirkten Rückführng5 frei, dann wird der Motor vom Endschalter abgeschaltet, sobald der Endschalter in seine Ausgangsstellung zurückkehren kann.The design of the limit switch as a two-pole reversing switch namely leads to the fact that when the seat approaches an obstacle so far Advice that the limit switch responds, reversing the direction of rotation of the drive motor is effected regardless of whether the operator uses the associated control switch releases when the limit switch is triggered or continues to hold actuated. Give the Operator the assigned control switch during the switchover the direction of rotation of the drive motor caused feedback5, then the motor switched off by the limit switch as soon as the limit switch returns to its starting position can.
Hält hingegen die Bedienungsperson den Steuerschalter auch dann noch in der eine Bewegung des Sitzes gegen das Hindernis vorgebenden Einschaltstellung, wenn der Endschalter vom Hindernis wieder freigekommen ist, dann bewirkt der Endschalter eine erneute Drehrichtungsumkehr des Antriebsmotors. Der Sitz bewegt sich dann wieder gegen das Hindernis9 bis der Endschalter erneut anspricht und wieder eine Rückführungsbewegung einleitet. Die Verstellwcge, die der Sitzbei diesem Pendeln im einen Endabschnitt des Verstellbereiches ausführt, wenn der zugehörige Steuerschalter zu lange betätigt wird, können jedoch so gering gehalten werden, daß sie nicht störend in Erscheinung treten. Von besonderem Vorteil ist auch der geringe Aufwand, den die erfindungsgemäße Lösung erfordert.On the other hand, if the operator still holds the control switch in the switch-on position that specifies a movement of the seat against the obstacle, when the limit switch has cleared the obstacle again, the limit switch operates another reversal of the direction of rotation of the drive motor. The seat then moves again against the obstacle9 until the limit switch responds again and another return movement initiates. The Verstellwcge that the seat with this pendulum in one end section of the adjustment range if the associated control switch is pressed for too long is, however, can be kept so small that they are not disturbing in appearance step. Also of particular advantage is the low outlay required by the inventive Solution requires.
Im folgenden ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im einzelnen erläutert.The invention is illustrated below with reference to one in the drawing Embodiment explained in detail.
Es zeigen: Fig. 1 eine schematisch dargestellte Seitenansicht eines Fahrzeugsitzes und eines unterhalb des vorderen Sitzrandes sich befindenden Hindernisses, Fig. 2 das Schaltbild des Ausführungsbeispiels.1 shows a schematically illustrated side view of a Vehicle seat and an obstacle below the front edge of the seat, 2 shows the circuit diagram of the exemplary embodiment.
Ein schematisch und unvollständig dargestellter Kraftfahrzeugsitz 101 übergreift mit dem vorderen Abschnitt seines Sitzteiles 102 ein Hindernis 103 in Form eines Querschwellers im Fahrzeugboden 104.A schematically and incompletely shown motor vehicle seat 101 overlaps an obstacle 103 with the front section of its seat part 102 in the form of a transverse sill in the vehicle floor 104.
Sowohl die Sitzhöhe als auch die Neigung der Sitzfläche des Kraftfahrzeugsitzes 101 kann verstellt und eingestellt werden. Hierzu greifen an der vorderen Hälfte des Sitzteiles 102 und an der hinteren Hälfte voneinander unabhängige Höhenverstellvorrichtungen 105 bzw. 106 an, die in Fig. 1 nur schematisch dargestellt sind und je einen Gleichstrommotor 107 bzw.Both the seat height and the inclination of the seat surface of the motor vehicle seat 101 can be adjusted and set. Use the front half for this of the seat part 102 and independent height adjustment devices on the rear half 105 and 106, which are only shown schematically in FIG. 1, and each have a direct current motor 107 or
108 aufweisen, welcher über ein Getriebe und eine schematisch dargestellte Mechanik den Sitzteil zu heben und zu senken Da vermag./die beiden Höhenverstellvorrichtungen 105 und 106 unabhängig voneinander wirksam gemacht werden können, kann mit ihrer Hilfe auch die Neigung des Sitzteils 102 verändert werden. Jeden der beiden Höhenverstellvorrichtungen 105 und 106 ist je eine Steuereinrichtung zugeordnet. Selbstverständlich wäre es aber auch möglich, die beiden Höhenverstellvorrichtungen mittels einer gemeinsamen Steuereinrichtung zu steuern.108 have, which is shown schematically via a transmission and a Mechanics to raise and lower the seat part 105 and 106 can be made effective independently of each other, can with their Help the inclination of the seat part 102 can also be changed. Each of the two height adjustment devices 105 and 106 are each assigned a control device. Of course it would but also possible, the two height adjustment devices by means of a common Control device to control.
Die der an der vorderen Hälfte des Sitzteils 102 angreifenden Höhenverstelleinrichtung 105 zugeordnete Steuereinrichtung 109 zeigt Fig. 2. Die Steuereinrichtung 109 besteht aus einem zweipoligen, von Hand zu betätigenden Drehrichtungs-Umkehrschalter 110 und einem Endschalter 111, der ebenfalls als zweipoliger Drehrichtungs-Umkehrschalter ausgebildet ist.The height adjustment device acting on the front half of the seat part 102 Control device 109 assigned to 105 is shown in FIG. 2. The control device 109 consists a two-pole, manually operated reversing switch 110 for the direction of rotation and a limit switch 111, which is also a two-pole reversing switch is trained.
Im Gegensatz zum Umschalter 110, der drei Schaltstellungen hat, kann der Endschalter 111 nur in der einen oder anderen Schaltstellung stehen, da er mit Umschaltsprungkontakten ausgerüstet ist.In contrast to the switch 110, the three switch positions Has, the limit switch 111 can only be in one or the other switch position, there it is equipped with changeover contacts.
Die beiden Anschlußklemmen des Gleichstrommotors 107 sind an 123 bzw. 124 das eine bzw. andere bewegliche KontaktstGck/des Endschalters 111 angeschlossen. Das eine der beiden,dembeweg-123 lichen Kontakts tückdes Endschalters 111 zugeordneten festen 125 undl6 Kontaktstücke /ist mit dem einen Pol, das entsprechendefeste Kontaktstück/der beiden1d2ef anderen beweglichen Kontaktstück 124 zugeordnetm Kontaktstücke/mit den anderen Pol der Spannungsquelle verbunden, und zwar derart, daß der Gleichstrommotor 107 eine das Abheben des Sitzteils 102 vom Hindernis 103 bewirkende Drehrichtung hat, wenn die beiden beweglichen Kontakt-123,124 125 und 127 stuck es Endschalters 111 diese festen KontaktstGcke/kontaktieren, was der Fall ist, wenn der Endschalter betätigt ist, sein Betätigungsglied also in Berührung mit; dem Hindernis 103 steht.The two terminals of the DC motor 107 are connected to 123 resp. 124 one or the other movable contact piece / of the limit switch 111 is connected. One of the two, the movable contact piece of the limit switch 111 assigned fixed 125 and 16 contact pieces / is with one pole, the corresponding fixed contact piece / the both1d2ef other movable contact piece 124 associated with the contact pieces / with the other pole of the voltage source connected, in such a way that the DC motor 107 a direction of rotation causing the seat part 102 to lift off the obstacle 103 has when the two moving contact-123,124 125 and 127 stuck it limit switch 111 these fixed contacts / contact, which is the case when the limit switch is actuated, so its actuator is in contact with; the obstacle 103 is.
128 und 126 Die beiden anderen festen Kontaktstücke'des Endschalters 111 sind mit dem einen bzw. anderen beweglichen Kontaktstück 116 bzw. 122 des Umschalters 110 verbunden. Die in Fig 2 dargestellte Mittelstellung dieser beiden beweglichen Kontaktstücke entspricht der Stellung des als Steuerschalter dienenden Umschalters 11-0, in der dieser Schalter nicht betätigt ist. Da das eine feste Xontaktstück 117 der beiden dem beweglichen Xontaktstücke 116 2%geordneten7 festen Kontaktstücke ebenso wie das andere feste Kontaktstück 121 der beiden dem anderen beweglichen Konaktstück 122 zugeordneten, festen Kontaktstücke mit demeinen Pol und die beiden dbrigen festen Kontaktstücke 119 und 120 mit des anderen Pol der Spannungsquelle in Verbindung stehen, bewirkt eine Be tätigung des Umschalters 110 im einen Sinne ein Einschalten des Gleichstrommotors 107 mit der einen Drehrichtung und eine Betätigung im anderen Sinne eine Einschaltung mit der anderen Drehrichtung. 128 and 126 The two other fixed contact pieces of the limit switch 111 are with one or the other movable contact piece 116 or 122 of the switch 110 connected. The middle position of these two movable ones shown in FIG Contact pieces correspond to the position of the changeover switch serving as a control switch 11-0 in which this switch is not operated. Because that's a solid contact piece 117 of the two 7 fixed contact pieces that are related to the movable contact pieces 116 2% just like the other fixed contact piece 121 of the two movable to the other Contact piece 122 associated, fixed contact pieces with one pole and the two Remaining fixed contact pieces 119 and 120 with the other pole of the voltage source are connected, causes a Be actuation of the switch 110 in a sense switching on the DC motor 107 with one direction of rotation and actuation in the other sense, switching on with the other direction of rotation.
Wird der Umschalter 110 derart betätigt, daß der Gleichstrommotor 107 den Sitzteil 102 gegen das Hindernis 103 bewegt, und wird der Umschalter 110 in diesem Zustand gehalten, nachdem der Endschalter 111 durch das Hindernis 103 betätigt worden ist, dann bewirkt die Umschaltung des Endschalters eine Umkehrung der Drehrichtung des Gleichstrommotors 107. Der Sitzteil 102 bewegt sich also wieder vom Hindernis 103 weg, und zwar bis zur Rückkehr des Endschalters 111 in seine Ausgangslage, falls bis zu diesem Zeitpunkt der Umschalter 110 freigegeben worden ist und in die in der Fig. 2 dargestellte Mittelstellung zurückgekehrt ist. Ist jedoch der Umschalter 110 bis zu diesem Zeitpunkt nicht freigegeben worden,dann hat die Rückkehr des Endschalters 111 in seine Ausgangslage zur Folge, daß die Drehrichtung des Gleichstrommotors 107 wieder umgekehrt wird. Der Sitzteil 102 nähert sich nun wieder dem Hindernis 103, bis der Endschalter 111 erneut anspricht und wieder eine Rückführungsbewdgung einleitet. Dieses Spiel wird erst beendet, wenn der Umschalter 110 freigegeben oder in seine andere Einschaltstellung gebracht wird. Dieses Spiel verhindert, daß eine gleichzeitig erfolgende Verstellung des hinteren Abschnittes des Sitzteils 102 nach oben mittels der hinteren Höhenverstellvorrichtung 106 zu einer Anlage des vorderen Abschnitts des Sitzteils 102 am Hindernis 103 führen kann, weil durch die Hin- und Herbewegung der vorderen Zone des Sitzteils 102 diese Zone sich höchstens so weit dem Hindernis 103 nähern kann, bis der Endschalter 111 zwangsläufig die Rückführungsbewegung einleitet.If the changeover switch 110 is operated so that the DC motor 107 moves the seat part 102 against the obstacle 103, and becomes the switch 110 held in this state after the limit switch 111 through the obstacle 103 has been actuated, the switching of the limit switch causes a reversal the direction of rotation of the DC motor 107. The seat part 102 therefore moves again away from obstacle 103 until the limit switch 111 returns to its starting position, if by this time the switch 110 has been released and in the has returned to the center position shown in FIG. However, is the toggle switch 110 has not been released by this time, then the limit switch has returned 111 in its starting position with the result that the direction of rotation of the DC motor 107 is reversed again. The seat part 102 now approaches the obstacle again 103, until the limit switch 111 responds again and again a return movement initiates. This game is only ended when the switch 110 is released or is brought into its other switch-on position. This game prevents one simultaneous adjustment of the rear portion of the seat part 102 according to above by means of the rear height adjustment device 106 to a plant of the front Section of the seat part 102 can lead to the obstacle 103 because of the back and forth Movement of the front zone of the seat part 102, this zone extends at most so far the obstacle 103 can approach until the limit switch 111 inevitably the return movement initiates.
