Abstract

Official abstract text for this publication.

A bumper structural body ( 100 ) includes a bumper reinforcement ( 10 ), energy absorbing members ( 30 a, 30 b ), and intermediate members ( 50 a, 50 b ). The sloped sections ( 12 a, 12 b ) of the bumper reinforcement ( 10 ) are connected to the energy absorbing members ( 30 a, 30 b ) and the intermediate members ( 50 a, 50 b ). The intermediate members ( 50 a, 50 b ) are each formed in a quadrilateral by connecting a first portion ( 51 ) contacting the energy absorbing member ( 30 a, 30 b ), a second portion ( 52 ) contacting the bumper reinforcement ( 10 ), and portions connecting the first portion ( 51 ) and the second portion ( 52 ).

First claim

Opening claim text (preview).

1 . A bumper structural body, comprising: a bumper reinforcement extending in a vehicle width direction of a vehicle; an energy absorbing member connected to a vehicle frame and to the bumper reinforcement; and an intermediate member arranged between the bumper reinforcement and the energy absorbing member, and joined to each of the bumper reinforcement and the energy absorbing member; wherein the bumper reinforcement is joined to each of the energy absorbing member and the intermediate member, the intermediate member includes: a first portion joined to the energy absorbing member, a second portion joined to the bumper reinforcement, and a third portion and a fourth portion that connects the first portion to the second portion, the first portion, the second portion, the third portion, and the fourth portion are connected so as to form a quadrilateral, an angle between the third portion and the fourth portion is larger than an angel between the first portion and the second portion, and an angle between the second portion and the third portion is equivalent to an angle between the fourth portion and the first portion. 2 . (canceled) 3 . The bumper structural body according to claim 1 , wherein: a line length of the first portion is equivalent to a line length of the second portion, and a line length of the third portion is equivalent to a line length of the fourth portion.
