The invention solves the problem of constructing such a head-rest of a seat in a vehicle, especially in a car, which can be moved manually or by means of remote control from the passive to active position and vice versa. According to the invention the head-rest is made up of the movable back squab (2) which is rotationally connected with the back of the seat, with the rotation plane of the back squab (2) being approximately corresponding to the plane of the back of the seat. The pin (3) is permanently connected with the back squab (2) and it rotates inside the sleeve (4) which is connected with the back of the seat. The pin (3) is connected with the blocking pad (5) furnished with the blocking's seat (6) with which the elastically supported locking pin (7) is mated. From the locking position the locking pin (7) is moved by means of either the lever (9) or electromagnet (11). In the second version the back squab (2) is moved by means of the worm gear.

Description

Rotatable head-rest of a seat in a vehicle
The subject of the invention is a rotatable head-rest of a seat in a vehicle, especially in a car There are many different types of head-rests of seats in cars In some of them their height in relation to the back of a seat can be changed in a step manner from the lowest to the highest position by means of moving the supports of a back squab inside sleeves furnished with elastic blocking elements which are mated with positioning notches made on the supports The other head-rests can take only two positions up and down They are usually intended for back seats of a car, and when they are in the down position, their upper edge should be as low as possible so as not to obstruct the rear view In order to fulfil their main function - the slowing down of the backward movement of the user's head during an accident - it should be possible to position them at the height where the head of a model person is Such head-rests have a lever supporting structure due to which the user may move the head-rest up and down The aim of the invention is the development of the head-rest which can be easily moved from the passive to active position, and which does not obstruct the rear view in its passive position, and does not need dismantling before folding the back of the back seat when wanting to increase the capacity of the luggage boot Moreover, the head-rest's structure should, depending on the model, allow for the local manual control or remote control This aim has been achieved through the construction of the head-rest which is made up of a moving part in the form of a back squab, a set of elements intended for rotational attachment of the earlier-mentioned back squab to the back of the seat, a set of elements intended for immobilisation of the back squab in the active position, and, related to this set, the unlocking mechanism which makes it possible for the back squab to return to the passive position The rotation plane of the back squab of a head-rest is approximately corresponding to the plane of the back of a seat The main elements designed for rotational attachment of the back squab to the back of the seat constitute the connection of the pin-sleeve type The elements used for locking the back squab in the active position preferably include s dable and elastically supported locking pin which is mated with the blocking's seat, with which the blocking pad is furnished There are many possible ways of assigning the elements mentioned to the movable back squab of the head-rest and to the immovable back of the seat the pin permanently connected with the back squab - the sleeve connected with the back of the seat or the other way round, the blocking pad connected with the movable element, e g the pin, if it is connected with the back squab - the locking pin connected with the back of the seat or the other way round
The unlocking mechanism which is used for withdrawing the locking pin from the blocking's seat preferably contains the unlocking lever
Preferably, the mechanism of moving the pin is electromagnet which can be remotely- controlled, for example, by the driver of a vehicle
In the other version the rotation of the head-rest is achieved by means of a transmission which is driven by an electric motor One part of the transmission is connected with the immovable back of the seat, while the other part is connected with the rotatable part of the head-rest, 1 e the back squab Preferably, the transmission is in the form of a worm gear, and the worm is located in the immovable part while the wormwheel is connected with the rotatable back squab
The idea of the invention is the same both when the back squab is placed directly in the back of the seat of a vehicle, and when the elements belonging to the immovable back of the seat and intended for rotational connection are placed in a separately-made part - immovable part of the head-rest which is permanently and rigidly connected with the back of a seat According to the invention the head-rest makes it possible to obtain the maximum rear view because in the passive position the upper edge of the immovable part is in line with the upper edge of the back of the seat, and it does not need to be dismantled before folding the back of the back seat when wanting to increase the capacity of the luggage boot Moreover, the structure of the head-rest allows for remote control, especially of the returning movement of the movable part to the passive position - in versions equipped with an electromagnet, or remote control of the change to/from the active position - in versions with a motor and a gear The subject of the invention has been closely explained in the examples of constructing the device where fig 1 shows a section of the head-rest in its first version with a lever, fig 2 - a section of the head-rest in its first version with an electromagnet, and fig 3 - a section of the head-rest in its second version
According to the first version of the invention the rotatable head-rest is made up of the immovable part I permanently attached to the back of the seat and the back squab of the headrest 2 which is rotationally connected with this immovable part The pin 3, which constitutes an axis of the earlier-mentioned back squab of the head-rest 2, is connected with the back squab 2 The pin 3 is placed inside a sleeve 4 which mounted in the immovable part of the head-rest 1 The pin 3 is permanently connected with the pad 5 in which there is a seat of the blocking 6 with which the locking pin 7 is mated The locking pin is supported with the spring 8 and connected with the unlocking lever 9 whose tip is always outside the head-rest The return spring K) is connected with the pin 3 The functioning of the head-rest is as follows
In order to change the position of the back squab 2 of the head-rest it is necessary to apply force to it and turn the back squab 2 to the active position in which it will be blocked since the locking pin 7 will enter the blocking's seat in the pad 5 which is permanently connected with the pin 3 In order to change the position into the passive one the locking pin 6 must be withdrawn from the blocking's seat in the pad 5 by means of the unlocking lever 9 while overcoming the resistance of the spring 8 When moving the movable part 2 of the head-rest from the passive into the active position the return spring J_0 is put under tension After releasing the blocking the return spring helps the back squab 2 of the head-rest to return to the passive position
In the second type of the first version the head-rest is made up of the immovable part I permanently attached to the back of the seat and the movable back squab 2 of the head-rest which is rotationally connected with this immovable part The pin 3, which constitutes an axis of rotation of the earlier-mentioned back squab of the head-rest 2, is connected with the back squab 2 The pin 3 is placed inside the sleeve 4 which is mounted in the immovable part of the head-rest I The return spring K) is connected with the pin 3 The pad 5 with the blocking's seat 6 in it which is mated with the locking pin 7 supported with the spring 8, is permanently connected with the pin 3 The locking pin 7 is connected with the electromagnet JO which is remotely operated, for example, by means of a switch located on the dashboard The functioning of the second type of the first version of the head-rest is as follows Putting of the back squab 2 of the head-rest into the active position is performed manually in the same way as in the first type However, during the change of the head-rest to the passive position the locking pin 7 is withdrawn from the blocking's seat 6 by means of the electromagnet K) which can be operated by a switch or pressure sensor In the second version the head-rest is made up of the immovable part 1 permanently attached to the back of the seat and the movable back squab 2 of the head-rest which is rotationally connected with this immovable part The pin 3, which constitutes the axis of rotation of the back squab 2, is connected with the back squab 2 The pin 3 is placed inside the sleeve 4 which mounted in the immovable part of the head-rest I In the immovable part I of the head-rest there is a worm gear driven by electric motor The wormwheel JJ_ of the worm gear is mounted on the pin 3 Electric signal is transmitted to the motor by means of an electric remote control from any place inside the vehicle The signal may come from a pressure sensor placed in the seat or from any other switch
The functioning of the second version of the head-rest is as follows
When the switch is operated the electric motor puts the worm in motion The wormwheel JJ_ which is mated with the worm turns the pin 3 with which it is coupled thus turning the movable part of the head-rest 2 till it takes the working position The passive position is reached by the movable part 2 of the head-rest in a similar way
