Bumper structure

Abstract

A recess (22) is formed at the center of a bumper absorber (20), provided on the vehicle outer side of a bumper reinforcement (16), so as to face forward, and an upper recess wall face (22A) of an upper absorber portion (24) located on the upper side of the recess (22) is inclined downward. If the subject vehicle is small in height and the amount of vertical overlap between the bumper absorber (20) and the rear bumper of other vehicle (a barrier (18) used in the narrow vertical overlap barrier test of the IIHS) is small, in the initial collision stage, the rear bumper of the other vehicle is guided by the inclined upper recess wall face (22A) to move relatively downward while the bumper of the subject vehicle moves relatively upward, preventing underride, increasing the amount of vertical overlap between the rear bumper of the other vehicle and the bumper absorber (20), and thus achieving reliable impact absorption.

Description

technical field

[0001] The present invention relates to a vehicle bumper structure, and more particularly to a bumper structure having a bumper absorber for absorbing the impact of a collision with an object. Background technique

[0002] Bumper absorbers (impact absorbing members) for absorbing impact at the time of collision are arranged on the vehicle longitudinal outer sides of the respective bumper reinforcements of the front and rear bumpers of the vehicle. Crash safety tests conducted by the Insurance Institute for Highway Safety (IIHS) in the United States include narrow vertical overlapping barrier tests. In this test, a curved barrier is used, the central portion of which is convex towards the outside in the longitudinal direction of the vehicle. The barrier was vertically deviated to partially overlap the bumper of the vehicle, and the front and rear sides of the vehicle collided with the barrier at 10 km / h.

[0003] In a case where the vehicle height is relativ...
