BUMPER DEVICE AND MOTOR VEHICLE

摘要

A bumper device for a motor vehicle is described. A cross member assembly includes a cross member running transverse to a traveling direction and a side element extending from an end of the cross member. A side member assembly has a first end configured to be fixed to a vehicle structure and a second end fixed to the cross member. A support member extends from the side member assembly towards an end of the side element opposite the cross member. The support member is configured to absorb and transfer an oblique load acting on the side element to the side member assembly, and to defect without substantial resistance to the longitudinal load acting on the cross member in the traveling direction.

主权项

1. A bumper device for a motor vehicle having a body structure, the bumper device comprising:
a cross member assembly including a cross member running transverse to a traveling direction and a side element extending from an end of cross member; a side member assembly having a first end configured to be fixed to a vehicle structure and a second end fixed to the cross member, the side member assembly including a deformation section whose extension in the traveling direction can be reduced when a longitudinal load acting on the side member assembly opposite the traveling direction has been exceeded; a support member extending between the side member assembly and an end of the side element opposite the cross member, wherein the support member is configured to absorb and transfer an oblique load acting on the side element to the side member assembly and to deflect under the longitudinal load acting on the cross member in the traveling direction without substantial resistance; and a receptacle extending from the side member assembly and including a guide section for guiding movement of the support member from a non-deformed position to a load-absorbing position, and a stop for limiting movement of the support member, wherein the guide section includes a recess in the side member assembly complementing a contour of the support member.
