A bumper reinforcement includes a front wall, a rear wall, and a connection wall. Intermediate portions, in an extending direction, of the front wall and the rear wall are parallel to each other. An end portion, in the extending direction, of the front wall is bent toward the rear wall when viewed from the intermediate portion of the front wall. An end portion, in the extending direction, of the connection wall includes a front part and a rear part, and each of the front and rear parts extends from an inside to an outside in the vehicle width direction. A distance between a front end of the rear part and the rear wall gradually decreases in a direction from a base end of the rear part toward a distal end thereof. The front part is provided so as to extend along the front end of the rear part.

Bumper reinforcement and method of manufacturing bumper reinforcement

The bumper reinforcement has a front surface flange, an upper surface web, a lower surface web, an upper lip, and a lower lip. An end of the upper surface web on the upper lip side is thicker than a center. When a collision load is applied to the front surface flange, the upper surface web extending in a direction orthogonal to the front surface flange from vicinity of an upper end of the front surface flange is deformed in an outward opened direction, and the upper lip extending downward from an extension end of the upper surface web is deformed in an inward closed direction.

Automotive bumper reinforcement

A bumper structure includes: a bumper reinforcement including: a hollow body portion extending in a vehicle width direction of a vehicle; and an extending portion arranged on one end portion of the hollow body portion in a longitudinal direction of the hollow body portion; and a side member, which is formed to extend in a vehicle front-and-rear direction of the vehicle, and is configured to support one end portion of the bumper reinforcement in a longitudinal direction of the bumper reinforcement. The extending portion includes: a proximal end portion to be sandwiched between the one end portion of the hollow body portion in the longitudinal direction of the hollow body portion and one end portion of the side member in a longitudinal direction of the side member; and a protruding portion formed to extend outward from the proximal end portion in the vehicle width direction. The side member includes a projecting portion protruding outward in the vehicle width direction. When an object collides against one end portion of the vehicle in the vehicle width direction to break the one end portion of the side member in the longitudinal direction of the side member, the protruding portion of the extending portion is abuttable against the projecting portion of the side member.

Bumper structure

A shock absorbing member provided between a side member extending in a front-rear direction of a vehicle and a bumper reinforcement extending in a vehicle width direction and provided at the side member, includes: a shock absorbing portion, which extends in the front-rear direction of the vehicle and is supported by the side member and which is configured to absorb an impact caused by a load by being compressed in the front-rear direction of the vehicle when the load is applied to the bumper reinforcement in at least one of a forward direction and a backward direction; and a bumper reinforcing portion, which extends from an end portion side closer to the side member in the impact absorbing portion toward a vehicle-width-direction outside and a bumper reinforcement side and which reinforces the vehicle-width-direction end portion side of the bumper reinforcement.
