Definitions

  • the present invention relates to a detachable backrest for a vehicle seat, in which the backrest comprises a headrest disposed on the backrest.
  • the headrest ...can be ...automatically released from a locking position using actuating means, whereupon the headrest, by means of a mechanism built into the headrest or the seat back, moves from a first position to a second position relative to the backrest when the backrest is tilted down in order, for example, to expand the loading space of the vehicle.
  • the passenger seats In many vehicles there is a requirement for the passenger seats to be able to be moved or tilted in different directions in order to enlarge the loading space of the vehicle.
  • the seat back In order further to increase flexibility in terms of utilizing the loading space, there is also a requirement in many vehicle applications for the seat back (a vehicle seat can be deemed to consist of two main parts: a seat cushion part and a seat back) to be able to be lifted fully out of the vehicle, in other words separated from the seat cushion part with which the seat back combines to make up the vehicle seat.
  • the seats are usually provided with a headrest for the comfort and safety of the passengers, and there is generally a mechanism present in the seat for tilting the headrest forward if the seat back is to be tilted forward, since the headrest might otherwise impede the tilting movement of the seat back.
  • a mechanism comprises a part which is fixed in or below the pivot point for the seat back, in other words a part which is fixed in the seat cushion part or elsewhere in the vehicle.
  • the present invention discloses a detachable backrest for a vehicle seat, comprising a headrest disposed on the backrest.
  • the backrest further comprises actuating means, by means of which the headrest is automatically released from a locking position when the backrest is tilted, whereupon the headrest, by means of a mechanism built into the headrest, moves from a first position to a second position relative to the backrest.
  • the actuating means for releasing the headrest from the locking position are disposed in the backrest and the actuating means are connected to the headrest by means of a wire extending in the backrest.
  • the backrest according to the invention accommodates all the parts, inclusive of the actuating means for the release of the headrest, the seat back can easily be lifted out of the vehicle, in other words released from the seat cushion part of the vehicle seat.
  • Fig 2 shows actuating means for a headrest in a seat back according to the invention.
  • Figs 1a-1c show a vehicle seat back 100 according to the invention and its -function.
  • .the. seat back. 100 according to the invention comprises a headrest 110, which, in Fig. 1a, is disposed in the position which it will normally have when a passenger is sitting in the seat.
  • this position of the headrest 110 is such that the headrest covers an upper part of the back of the vehicle seat, in other words the headrest is in a position which offers support for a head.
  • the headrest 110 is disposed around the crossbar in a bracket 101 which sticks up out of the seat back and which is indicated in Fig. 1a.
  • the seat back 100 has started to be tilted forwards towards the floor of the vehicle, for example in order to be able to increase the loading space of the vehicle. If the headrest 110 were to maintain the position from Fig. 1a, it might catch, for example, the seat cushion part of its own seat or the seat back in front and thereby impede part of the forward tilting of the seat back 100.
  • the headrest 110 in the seat back 100 comprises a mechanism by means of which the headrest, when the seat back 100 is tilted forward, will be swivelled out to an angular position in which the headrest 110, once the seat back 100 is tilted down, assumes a position in which the headrest juts out in front of the seat cushion part, down towards the floor of the vehicle.
  • this mechanism can also be disposed in the seat back.
  • Fig. 1 b The start of the movement of the headrest towards the said angular position is shown in Fig. 1 b and the final position of the headrest cushion 110 in the tilted-down position of the seat back is shown in Fig. 1c.
  • a facility has been shown for enlarging the loading space in a vehicle, namely for tilting forward the seat back in one of the vehicle seats.
  • Another facility or requirement is for the seat back to able to be lifted fully out of the vehicle, the seat back being separated from its seat cushion part.
  • the mechanism which is shown in Figs Ia-Ic and which executes the tilting- forward of the headrest comprises in existing solutions a part which is disposed below the pivot point of the seat back, in other words in the seat cushion part or in another part of the vehicle. In such solutions, it is impossible, in other words, to easily release the seat back in order to be able to lift it out of the vehicle.
  • the abovementioned mechanism which ensures that the headrest is swivelled out to the position shown in Fig. 1c can be realized in many different ways within the scope of the invention.
  • the principle is, however, that the headrest, by means of a tilting mechanism, can move between a first (Fig. 1a) and a second position (Fig. 1c), in which the headrest is locked in the first position by a mechanism (not shown) for locking and releasing the said lock.
  • a mechanism not shown
  • the locking and release mechanism of the headrest (which might be an integrated part of the tilting mechanism of the headrest), using actuating means, can be released from the said locking position and can hereupon assume a second position, for example that which is shown in Fig. 1c.
  • first position from which the headrest is released by means of the invention may in principle be any position whatsoever, which is also applicable to the second position, the essential point being that the invention allows the release of a headrest from a first position and its movement into a second position.
  • the actuating means for releasing the headrest from the locking position are disposed in the backrest and are shown symbolically in Figs Ia-Ic, denoted by the numeral 120.
  • the release mechanism which is present for releasing the headrest from the locking position can be actuated for release purposes by means of an external tensile force, for example by means of a wire running in the backrest 100 from the release mechanism of the headrest to the actuating means 120.
  • Fig. 2 shows an example of an embodiment of the external actuating means 120; the means 120 suitably comprise a housing 125.
  • the wire 130 runs into the housing 125 and is there fastened to a first arm 135, which first arm 135 is disposed pivotably about an axis 140.
  • the actuating means 120 further comprise a second arm 145, which, when actuated by a user, makes the first arm 135 pivot about the axis 140, thereby producing a pulling action in the wire 130.
  • the second arm 145 will be actuated when the seat back is tilted, suitably by it running through the housing 125 such that one end of the arm is perceived by a user as a knob or a pin. This knob or pin then becomes all that the user sees of the actuating means 120, the rest can be inserted in the seat back.
  • the second arm 145 extends through the housing and is inserted by its other end in a recess in the first arm 135.
  • the actuating means 120 further comprise a first spring 150, disposed such that its spring action endeavours to counteract the action of the second arm 145 upon the first arm 135.
  • the device might also comprise a second spring (not shown in Fig. 2).
  • This second spring would then be disposed in the housing 125 and would endeavour to return the arm 145 relative to the housing, in other words assist the first spring 150.
  • Figs 1a-1c the actuating means are shown symbolically in Figs 1a-1c, denoted by 120.
  • the arm 145 protruding beyond the housing 125. It should be emphasized that neither this part of the arm nor some other part of the actuating means 120 engages in the bottom of the seat, but runs completely free from the seat bottom.
  • the actuating means 120 can be disposed such that, upon forward movement of the seat back, they pass against a cam 122 disposed in the body of the vehicle, whereupon the protruding part of the arm 145 will gradually be forced more and more into the housing 125 and will press upon the first arm 135, thereby causing the latter to rotate about the axis 140.
  • That the arm is gradually pressed more and more in as the seat back 100 is tilted forwards is due to the fact that the tilting movement is not a linear movement, but a swivel movement about a centre of rotation 127, indicated in Figs 1a-1c.
