Abstract
An installation for the energy absorption of motor vehicles, in which a deformation member has a wall structure delimiting a hollow space which cooperates with a pressure installation that acts upon the hollow space during an accident in dependence on a trigger mechanism and thereby deforms the wall structure in such a manner that the energy absorption efficacy of the deformation member is increased.
Claims15
An energy absorbing installation for vehicles comprising:
- means for increasing the denting and buckling stength of a vehicle body member including a deformation means having a wall structure defining a hollow space, and being associated with a vehicle body member, the vehicle body member in its undeformed configuration defining a portion of a vehicle body profile;
- pressurizing means in communication with said hollow space for generating an increase in pressure within said space sufficient to outwardly deform said wall structure and said body member;
- and
- triggering means operatively connected to said pressurizing means and responsive to a vehicle collision for actuating said pressurizing means and thereby increasing the denting and buckling strength of said vehicle body member, and accordingly the energy absorbing ability by virtue of the changed shape produced.
