AUTOMOBILE BUMPER

WIPO Patent Application WO/2015/104889

A1

An automobile bumper is configured in such a manner that a bumper beam (11) comprises: a center curved section (A) which is curved rearward in a recessed shape; and a pair of left and right curved sections (B) which are curved rearward in a protruding shape. The left and right curved sections (B) are provided with rear side-frame connection sections (B1) and load input sections (B), the load input sections (B2) protruding farthest rearward among the portions of the bumper beam (11), and therefore, in a rear face collision, compression loads act on the load input sections (B2) on the outside, in the width direction of the vehicle, of a pair of load input points (P). The bumper beam (11) is provided with compression-resistant reinforcement sections (13) provided along the inner surfaces, in the front-rear direction, of the load input sections (B2). Lines (L) extended from the compression-resistant reinforcement sections (13) are directed to the vicinities of the load input points (P) of the load input sections (B2), and therefore, the compression loads are supported at the compression-resistant reinforcement sections (13) to prevent the breaking of the bumper beam (11). As a result of this configuration, the strength of the bumper beam (11) against bending deformation can be increased without reinforcement made by increasing the plate thickness of the bumper beam (11).
