Motor vehicle seat, has armature with upper part folded towards front so as to be entered in plane parallel to another plane, where zone of armature between planes forms top deflection zone that allows energy absorption

摘要

The seat (1) has a headrest cushion (3) associated to a backrest (2) by a reversed U shaped metallic armature (4), where the seat has a minimal dimension (6) of 600 mm. The armature has a part (5) projecting from top of a structure of the backrest. The armature has an upper part (7) folded towards front so as to be entered in a plane parallel to a plane defined by a lower part of branches of the armature. A zone of the armature between the planes forms a top deflection zone (8) that allows energy absorption and is complementary to a bottom deflection zone (10).
