Reinforcement for folding backrest of i.e. 1/3 to 2/3 split folding rear seat, of motor vehicle, has lattices of metallic wires with fine drawn wire of diameter less than or equal to specific millimeters and with energy absorption set

摘要

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.
