The reinforcement (1) has a metal frame (2) in which lattices of metallic wires (3) forming a rear face of a backrest are stretched, where the lattices of metallic wires comprise a fine drawn wire (4) of diameter less than or equal to 6.4 millimeters. The fine drawn wire comprises an energy absorption set (5), which is located near a hooking zone for hooking of the fine drawn wire with the frame. The energy absorption set is formed in S-shape, and the fine drawn wire is welded to the frame by its ends forming the hooking zone. |
