Improved energy-absorber assembly for a motor vehicle, comprising a plastic tube forced through a grooving support preferably made by stamping

摘要

The assembly (3) has a grooving support (5) with a plate (13) integrated to an end of a rail. A tubular guiding sleeve (18) extends at rear of the plate to be housed inside a hollow end of the rail. A plastic absorption tube (4) has a rear end (11) engaged across a central opening and the sleeve. The tube is forced in advancement across the opening and in the sleeve during a longitudinal impact. A side wall of the sleeve is in guiding contact with an outer surface of a side wall of the tube engaged in the sleeve, where the wall of the sleeve allows tight guiding for the advancement of tube. An independent claim is also included for a method for manufacturing a kinetic energy absorbing assembly.
