Document Type and Number:
WIPO Patent Application WO/2012/033370
Kind Code:
A3
Abstract:
The present invention relates to a crash box for a front or rear bumper beam assembly for a vehicle, wherein the performance of the crash box satisfies the requirements for a low-speed crash test. The crash box comprises: a front plate member connected to a bumper beam; a rear plate member connected to a member; an outer support member which interconnects the front plate member and the rear plate member; and an inner support member which interconnects the front plate member and the rear plate member, and which is arranged in the vicinity of the outer support member. The outer support member and the inner support member each have a vertical wall and upper and lower horizontal walls. The vertical walls of the outer support member and inner support member are formed on the outer surfaces of the respective support members. The inner edges of the upper and lower horizontal walls are inclined from the rear portions thereof toward front center portions thereof. Thus, the performance of the crash box of the present invention may satisfy the requirements for both an offset test and a barrier test, reduce the weight of the bumper beam assembly to thereby reduce costs, and improve the performance and fuel efficiency of the vehicle.
