ABSTRACT:
At least one toothed roller cooperates with a deformable bar with respect to a casing which contains at least one V-shaped cam. The V-shaped cam has a central portion with opposed toothed ramps cooperating both with the toothed roller. A control cam acting on the V-shaped cam for permitting a blockage of the whole assembly is provided. The deformable bar is either made of vertical blades assembled and fixed to one another or provided with transverse bores. The bar will be deformed under action of the toothed roller upon great impact in an accident.
