Abstract
A deformable, polypropylene-moulding lining (11), is provided in a head rest. It has a crosspiece (12), clipped (14) to the head support (5) and right and left deformable wings (15, 16). These are longer than the support wings (5, 6) of the head part (4), extending past distal edges (17) of the support wings. The deformable wings are spaced inwards from the support wings, with voids (18) defined between them. The deformable wings are divided into two in their forwards extent by a living hinge (19) into a front portion (20) and a rear portion (21). The living hinge is positioned just inside the distal edges of the shell wings. The injection moulded lining has its own foam materiel lining (22), the whole being covered with upholstery (23). The result of the arrangement is that if an occupant's head H impacts the lining in side impact of the vehicle equipped with the seat, the relevant lining wing will be pressed against the shell wing. This involves energy absorbing (maximum acceleration limiting) deformation of not only the foam material, but also of the lining wing and to a less extent of the shell wing. With the lining wing deformation (24), the front portion (20) of the lining wing pivots forwards about the shell edge (17), from a position swept back with respect to the shell wing to a position generally in line with the compressed inner portion of the lining.
