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.
