Abstract
Abstract An improved bumper for an automotive vehicle which in case of a front collision near its end does not get bent into the vehicle wheel and lock the steering; the bumper being formed of separate end sections bolted to a central main section so that in case of a collision, the end section simply breaks off and falls away so to not interfere with the front wheel steering.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
163 words
A break away bumper assembly for a motor vehicle, comprising a central bumper mounted rigidly on the front end of the vehicle extending to planes parallel to and spaced from the inner surfaces of the front wheels of the vehicle in combination with a pair of extensions attached to opposite ends of said central bumper by frangible bolts secured to the central bumper and to each extension, wherein each bolt overlaps adjacent portions of the central bumper and each extension, said extensions projecting from the opposite ends of the central bumper to vertical planes parallel to and outward of the outer surfaces of the front wheels wherein the extensions and the central bumper have front surfaces in planar alignment and include aligned lugs mounted on said surfaces to receive said bolts spaced from and parallel to said surfaces, whereby collision impact on said extensions will break the bolts causing the extensions to fall away from the central bumper for possible further usage thereon.
Claim 2
Dependent Claim
163 words
A break away bumper assembly for a motor vehicle, comprising a central bumper mounted rigidly on the front end of the vehicle extending to planes parallel to and spaced from the inner surfaces of the front wheels of the vehicle in combination with a pair of extensions attached to opposite ends of said central bumper by frangible bolts secured to the central bumper and to each extension, wherein each bolt overlaps adjacent portions of the central bumper and each extension, said extensions projecting from the opposite ends of the central bumper to vertical planes parallel to and outward of the outer surfaces of the front wheels wherein the extensions and the central bumper have front surfaces in planar alignment and include aligned lugs mounted on said surfaces to receive said bolts spaced from and parallel to said surfaces, whereby collision impact on said extensions will break the bolts causing the extensions to fall away from the central bumper for possible further usage thereon.
Claim 3
Dependent Claim
96 words
An assembly as in claim 1 wherein the extensions each abut and overlap the ends of the central bumper and include transverse aligned holes adapted to receive said bolts in further combination with means further locking the extensions and the central bumper preventing sliding motion of the extensions relative to the central bumper, said means being responsive to collision impact on the extensions to release the extensions and permit sliding motion relative to the central bumper, in still further combination with retracting means urging the extensions to a position behind and secured to the central bumper.
