Braked sliding sidewall and door

Abstract

A vehicle sidewall or door designed to protect against intruding structural elements during a collision, comprising a braked-sliding, chain-guided, truss force transmission system in the central belt line with crumple element and swinging ribs, including: ·a truss (1) welded from below to a hinged massive window frame, ·three pairs of hinged structures (2a, 2b, 2c) connected to the bottom of the truss (1), ·three swinging ribs (3a, 3b, 3c) hanging from the hinged structures (2a, 2b, 2c), where, in the event of accidental collisions, these hanging swinging ribs (3a,b,c) can move due to the deformation resistance of a sized external (5a, 5b) and internal (6a, 6b) crumple element guided by a guide chain (4) that also moves, thereby realizing the braked sliding passive protection system, where the braked sliding occurs by a measured, decelerating change of direction controlled by chains (4), wherein the crumple zone is formed to a maximum depth (8b) and height (8a) by plates of maximum 1.2 mm thickness, so that the intruding elements can continue under the leg.
