Abstract

Abstract The present invention relates to vehicle bumper assemblies of the type which includes at least one profiled, preferably Ushaped beam or the like adapted to be securely mounted to the frame and/or the body of the vehicle in a manner whereby the outer contours of the bumper are located outside the vehicle body or part thereof and are active in a shock absorbing capacity. Such an envisaged assembly is provided with a number of shock absorbing insert members arranged to bear against the web of the beam structure and to extend externally of the beam profile to an extent which is at least one fourth of its total height. It is basically characterized in that the beam is provided with a plurality of stays or plates which extend transversely between the longitudinally extending limb portions of said beam and which divide the beam into pocket-like sections in which the inserts are individually mountably arranged. The inserts preferably comprise cellular blocks and consist of a number of tubes of a semi-elastic or plastic material. A protective casing surrounding the beam and the inserts has an open longitudinally extending groove arranged in its rear side. This permits the casing to be stretched when mounted in position.

Claim 1
Independent Claim 161 words
A vehicle bumper including at least one profiled, preferably U-shaped beam or the like intended to be securely mounted to the frame and/or body of the vehicle, and a number of shock absorbing inserts arranged to abut the web of the beam and to extend outside the profile of the beam to a distance of at least one fourth the total height of the beam, characterized in that the beam is provided with a number of stays or plates which extend transversely between the longitudinally extending limb portions of the beam and which divide the beam into pocket-like sections in which the inserts are individually mountably arranged; that the inserts preferably comprise cellular blocks and consist of a number of tubes of a semi-elastic or plastic material, and that a protective casing surrounding the beam and the inserts has an open longitudinally extending groove arranged in its rear side which permits the casing to be stretched when being mounted in position.
