Abstract

The invention relates to a headrest, particularly for a motor vehicle seat, comprising a cushion made from synthetic foam which houses an integrated support that can be used to fix two parallel anchor rods to the seat. According to the invention, the anchor rods are fitted with threaded shafts that extend at a right angle from the upper end of said rods. The threaded shafts are each screwed into one end of a housing body in the form of a cylindrical sleeve having a suitable internal threading. Tightening locknuts are used to lock the anchor rods in position on the cylindrical sleeve. Said cylindrical sleeve is fixed to a locking lug, which is disposed on the integrated support, by means of a stirrup piece which is associated with a screw-nut type tightening system.

Claims

1. A headrest, in particular for motor vehicle seats, made up of a synthetic foam cushion (2) that encloses an integrated support (12) to enable two parallel anchor rods (6) to be fitted onto the receiving seat (7),

wherein it has anchor rods (6) equipped with threaded shafts (18) that extend at a right angle from their upper end, each of the threaded shafts (18) getting screwed into one of the ends of a body (19) equipped with a suitable inner threading and linked to the means (24, 25 26) to fit it onto the integrated support (12).

2. The headrest as recited in claim 1,

wherein the threaded shafts (18) linked to the anchor rods (6) each have a locknut (22) adapted to abut against the body (19) so as to tighten the position of the anchor rods (6).

3. The headrest as recited in claim 1 or 2,

wherein the body (19) of the threaded shafts (18) includes a cylindrical sleeve, the sleeve (19) being housed in the base of an attached flat, U-shaped stirrup piece (24), the stirrup piece (24) enclosing a locking lug (30) situated on the integrated support (12) and affixed to the locking lug (30) via a screw-nut tightening system (25-26).

4. The headrest as recited in claim 3,

wherein it has an integrated support (12) equipped with a seat (28) suited to receive the cylindrical sleeve (19) and the threaded shafts (18) that extend the upper ends of the anchor rods (6) at a right angle, with the seat (28), which ends at the front face or the back face of the support (12), being positioned just below the locking lug (30) of the U-shaped stirrup piece (24), and the seat (28) having lower openings (29) for passage of the anchor rods (6), the openings (29) being adapted to the various potential distances between the anchor rods (6).

5. The headrest as recited in claim 4,

wherein the seat (28) of the support (12) has an opening (35) situated below the locking lug (30) in order to facilitate the positioning of the U-shaped stirrup piece (24).

6. The headrest as recited in claims 1 through 5,

wherein it has attached adapter sleeves (37), capable of compensating for the difference between the outer diameter of the anchor rods (6) and the inner diameter of the housing sleeve (20) installed in the upper portion of the receiving seat (7), the adapter sleeves (37) having an upper flange (38) allowing them to be held on the housing sleeves (20).

7. The headrest as recited in any of claims 1 through 6,

wherein it has a monitor (8) of the liquid crystal type for DVD players or for game consoles for example, embedded in its rear face, the monitor (8) being moveably clamped into a casing (14) which is itself embedded in the rear face and fixed on the integrated support (12).

8. The headrest as recited in claim 7,

wherein it has a monitor casing (14) embedded in a housing (4′

) situated at the rear face of the foam cushion (2), the housing (4′

) being delimited by a rigid frame (10) whose width essentially corresponds to the thickness of the casing (14) and along the inner rim of which the integrated support comes to rest, the base of the casing (14) being fixed to the integrated support (12) via locking screws (15) and the front face of the casing (14) being equipped with an oversize peripheral flange (16) adapted to come to rest against the outer rim of the rigid frame (10).

9. The headrest as recited in claim 8,

wherein it has a synthetic foam cushion (2) that is molded onto the rigid frame (10).

10. The headrest as recited in any of claims 7 through 9,

wherein it has hollow anchor rods (6), the power supply cables (40) of the monitor (8) passing through at least one of these rods.
