Abstract
The invention concerns a bumper for a motor vehicle which is constructed mainly of molded plastic parts and optically appears to be part of the vehicle body. The bumper consists mainly of a support part (10) extending across the vehicle, three absorbing elements (12, 14, 14') that can be inserted into the support part, and an elastic exterior shell (16). On the lateral end sections, the support part (10) has lateral shells (22, 22') which extend between the lateral absorbing elements (14, 14') and the exterior shell (16). In a collision, the lateral shells (22, 22') yield backwards under the deformation of the absorbing elements (14, 14'), so that components attached to the lateral shells are protected from damage.
Claims18
A bumper for a motor vehicle comprising an elongated support which can be attached to the front or rear of the motor vehicle body and which spans the width of the motor vehicle body, a shock absorber extending along the support part and extending towards the front or rear of the motor vehicle body in a substantially convex manner, and an elastic exterior shell which can be connected to the support part and which encompasses the front or rear of the motor vehicle in an approximate U shape, covering the side of the support part opposite the side facing the front or rear of the motor vehicle body wherein the support part has a middle section that can be firmly supported on the vehicle body, and two lateral shells adjacent to the sides of the middle section and extending between the shock absorber and the exterior shell, wherein
- the shock absorber is constructed with separate absorbing elements in sections, whereby a central absorbing element can be inserted in a hollow that is limited by the exterior shell and the middle section of the support part, and whereby two lateral absorbing elements can be inserted into the lateral shells of the support part that is open to the vehicle body, and wherein the lateral absorber elements have lock notches at their faces that can lock into locking points on the support part.
