Embodiment Construction

[0031] A first embodiment of the present disclosure will be described below with reference to the description of the drawings. exist image 3 A plan view of is showing a bumper device for a vehicle such as an automobile according to the first embodiment. Such as image 3 As shown, a pair of side members 11 made of, for example, a metal plate and extending in the longitudinal direction of the vehicle are arranged in the width direction of the vehicle. Each of the side members 11 corresponds to a hollow member having a cross-section of a substantially rectangular shape. The pair of side members 11 constitute a part of the vehicle body. Brackets 12 are welded to corresponding front ends of side members 11 to close corresponding openings of side members 11 . Each of the brackets 12 made of, for example, a metal plate is formed in a substantially rectangular shape.

[0032] A pair of smash boxes 13 are attached to respective front surfaces of brackets 12 welded to side members...

Abstract

A bumper reinforcement (16, 40) having end portions in the width direction of a vehicle, includes a main wall (21, 41) extending in a first direction perpendicular to the width direction, first and second walls (22, 23 / 42, 43) protruding from the main wall (21, 41) in the first direction to extend toward an interior side of the vehicle in a longitudinal direction of the vehicle, flanges (24, 44) protruding from respective ends of the first and second walls (22, 23 / 42, 43) along the first direction, the main wall (21, 41), the first and second walls (22, 23 / 42, 43), and the flanges (24, 44) being integrally formed with one another, and gradually narrowing portions (22b, 23b / 42b, 43b) formed, in the width direction, at end portions of each of the first and second walls (22, 23 / 42, 43), wherein respective protruding lengths of the first and second walls (22, 23 / 42, 43) in the longitudinal direction gradually decrease from an intermediate portion of the bumper reinforcement (16, 40) to the end portions of the bumper reinforcement (16, 40) in the width direction to form the gradually narrowing portions (22b, 23b / 42b, 43b).

Description

technical field [0001] The present disclosure generally relates to a bumper reinforcement and a bumper arrangement arranged on a vehicle such as an automobile. Background technique [0002] A known bumper reinforcement for vehicles is disclosed in JP2006-151095A (hereinafter referred to as reference 1). Such as Figure 7A with 7B As shown, the bumper reinforcement 91 includes a main body 92 formed of an extruded member extending in the width direction of the vehicle. Both end portions in the width direction of the main body 92 are bent toward the vehicle body and cut diagonally. The bumper reinforcement 91 also includes a reinforcement member 93 having a groove portion. The reinforcing member 93 is attached to the cut surface of each of the ends of the main body 92 from the front side of the vehicle, whereby an inclined surface conforming to the design of the vehicle can be obtained at the ends of the main body 92 without the ends being overwhelmed. curved. In addition,...
