Definitions
- Headrest assembly for a seat in particular for a motor vehicle
- the present invention relates to a headrest assembly and more particularly such an assembly comprising at least one spindle for mounting on a seat back, in particular for a motor vehicle, and a support cushion articulated on said spindle
- FIGS. 1 and 2 show in section, respectively from the front and side, such a headrest assembly of the prior art.
- the articulations 1 are arranged at the upper part of the mounting pins 2. To allow the movement of the headrest cushion 3 according to arrow F in FIG. 2, it is necessary to have the articulations 1 inside protective casings 4 and bring out the pins 2 in these housings by travel eyelets 5 elongated in the direction of the vehicle. Thus, when the cushion 3 pivots around the articulation 1, the pins 2 move from one end to the other of the slot delimited by the eyelets 5.
- the present invention aims to overcome these drawbacks.
- the subject of the invention is a headrest assembly comprising at least one pin for mounting on a seat back, in particular of a motor vehicle seat, and an articulated support cushion, characterized in that the cushion support comprises a first part into which said pin enters and which is fixed relative to this pin, and a second hinged part relative to the first part.
- the pins penetrate into a part of the cushion which is fixed relative to them, no deflection device is necessary and, in in particular, the eyelets can be eliminated.
- the housings can also be removed if the joint does not require sealing and if it does not have sharp corners which should be protected for safety reasons.
- said second part of the cushion is articulated at its upper part
- This arrangement is therefore the opposite of the usual arrangement where the support cushion is articulated at its lower part.
- the first part of the cushion therefore extends downwards from the top of the second, mobile part of the cushion.
- said support cushion may comprise a frame embedded in a volume of foam, for example a plate mounted along one of its pivoting edges relative to the upper end of said pin.
- the assembly according to the invention may also include adjustment means, for example a pawl, a push button or a scroll wheel.
- FIG. 3 illustrates in cross section the principle of a headrest assembly according to the invention
- - your Figure 4 is a view similar to Figure 3 of a particular embodiment.
- a headrest assembly according to the invention a cushion 10 in two parts 10a and 10b hinged relative to each other.
- This support cushion is mounted on mounting pins 11 fixed to the back of a seat by any known means.
- the pins 11 come out of the interior of the support cushion 10 through the lower part of the part 10a of this cushion.
- This part 10a is fixed relative to the pins 11 so that no deflection device is necessary at the level where the pin comes out of the cushion.
- An armature 12 is provided inside the part 10b of the cushion 10 and this armature 12 is articulated by an articulation 13 at the end of the pins 11.
- the joints 13 are formed at the upper part of the part 10b of the cushion 10 so that the parts 10a and 10b form an acute angle between them and that the cushion 10 has, in general, in section transverse, an inverted V shape.
- the frame of the second part 10b of the cushion consists of a plate 14, here curved, defining the general plane of the part 10b.
- This plate 14 is reinforced by ribs 15.
- the plate 14 and the ribs 15 can be made of sheet metal or molded in one piece from plastic.
- the plate 14 is mounted along its upper edge on an axis 16 carried at the upper end of the pins 11
- a ratchet system makes it possible to adjust the inclination of the part 10b of the support cushion 10 relative to its part 10a.
- This system here comprises a toothed part 16 mounted integral with a rib 15 and a part with complementary teeth 17 articulated on the fixed part 10a of the cushion and pressed against the part 16 by elastic means not shown
- energy absorbing devices 18 of any known type are also provided, integral with the pins 11 and facing part 10b of the support cushion. These energy absorbing devices 18 are embedded in the part 10a of the cushion When a violent force is exerted on the part 10b of the cushion, in the direction of the arrow F1, this part comes to be pressed against the part 10a and the energy of the shock is absorbed by the devices 18 La the user's head is thus protected from a violent shock
- the support cushion 10 can be made in any suitable way.
- it can be made of an expanded polyurethane foam 19 embedding all the devices described above, molded in situ inside an envelope 20 forming a cavity.
- unique molding and made of any suitable material such as fabric or plastic
- this headrest is carried out by first making the envelope in the seam of which three holes are reserved, two for the passage of the pins 11 and the third for the injection of the foam
- the assembly constituted by the pins, the frame and the joints are then put in place with the envelope previously laid flat This assembly and the envelope are then folded
- the molding is carried out with the parts 10a and 10b of the cushion in an intermediate relative angular position
- the packing material 19 must have sufficient flexibility to allow the desired clearance between the parts 10a and 10b of the cushion.
