Abstract
The energy absorber system is adapted to a motor vehicle having side rails. The system comprises a top absorber beam positioning in front of the side rails of the motor vehicle, a bottom absorber beam for being positioned beneath the top absorber beam, and at least two uprights providing a rigid connection between the top and bottom beams. The system also includes a rigid cross-member extending between the side rails and being secured directly to the side rails, the top beam being secured to bear against the cross-member.
Claims11
An energy absorber system for a motor vehicle provided with side rails and a low structure, the system comprising:
- a top absorber beam for being disposed in front of the side rails of the motor vehicle, extending substantially horizontally when the system is mounted on the motor vehicle;
- a bottom absorber beam for being disposed beneath the top absorber beam, extending substantially horizontally, and being secured to bear against extensions of the low structure, when the system is mounted on the motor vehicle;
- at least two uprights providing a rigid connection between the top and bottom beams, extending substantially vertically between an end of a top absorber beam and an end of a bottom absorber beam, when the system is mounted on the motor vehicle;
- and
- a rigid cross-member extending between the side rails and being secured directly to the side rails, the top beam being secured to bear against the cross-member, the rigid cross-member extending along an entire length of the top absorber beam.
A method of mounting an energy absorber system on a motor vehicle, the method comprising:
- a step of molding a top absorber beam, a bottom absorber beam, and at least two uprights providing a rigid connection between the top and bottom beams as a single piece, so that the top and bottom absorber beams extend substantially horizontally and the two uprights extend substantially vertically between an end of a top end of the top absorber beam and an end of the bottom absorber beam, when the system is mounted on the motor vehicle;
- a step of fastening the top beam to bear against a rigid cross-member extending along an entire length of the top absorber beam;
- and
- a step of securing the rigid cross-member to side rails of the motor vehicle so that the bottom absorber beam is secured to bear against extensions of a low structure of the vehicle.
