Abstract
Abstract The vehicle seat back includes two deformable elements both extending across the back (2) between two lateral uprights (3) defining the sides of the back, the elements comprising a first element (7) suitable for dissipating energy by deforming plastically in progressive manner, and a second element (8) suitable for stopping deformation of the first, the second element being disposed in such a manner that when a strong longitudinal thrust is applied to its middle portion, it begins by lengthening while offering practically no resistance until it reaches a given length, after which it becomes inextensible.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A vehicle seat back comprising two deformable elements both extending across the back between two lateral uprights defining the sides of the back, said elements comprising a first element suitable for dissipating energy by deforming plastically in progressive manner, and a second element suitable for stopping deformation of the first element, said second element being disposed in such a manner that when large longitudinal thrust is applied to its middle portion, practically no resistance until said second element begins by lengthening while offering said second element reaches a given length, and thereafter becomes inextensible.
