Longitudinal support for vehicle, especially motor vehicle, has energy absorbing device(s) that interacts with piston-cylinder arrangement activated in collision, especially frontal collision with energy absorption by energy absorber

摘要

The longitudinal support (1) is fitted between a transverse bumper support (2) and a passenger cell (3). The longitudinal support has at least one tube section (7) mounted on the passenger cell in a fixed position and containing a movable piston (9) connected to a piston rod (10) joined to the transverse support and at least one energy absorbing device (7;9;10;11;12;14) that interacts with the piston-cylinder arrangement, which is activated in the event of a collision, especially a frontal collision with energy absorption by the piston-cylinder arrangement.
