摘要： An impact absorber includes a energy absorbing member that is formed of a composite material obtained by reinforcing a resin with a fiber and absorbs impact energy by being crushed in a predetermined crush direction, and a pressing member that is disposed on the front side of the energy absorbing member and presses it in the crush direction to thereby crush the energy absorbing member. The energy absorbing member is configured by stacking, along a radial direction orthogonal to the crush direction, fiber layers having different elastic moduli to a load along the crush direction, and the front end portion of the energy absorbing member is inclined relative to a pressing surface of the pressing member such that the fiber layers are gradually brought into contact with the pressing member sequentially in ascending order of the elastic modulus as the energy absorbing member is pressed by the pressing member.

摘要： An impact absorber includes an energy absorbing member that is formed of a composite material and absorbs impact energy by crushing in a predetermined crush direction, an outer tube member surrounding the periphery of the energy absorbing member over the energy absorbing member along the crush direction to prevent foreign objects from entering or impacting the energy absorbing member, and a pressing member in contact with the front end of the energy absorbing member and the front end of the outer tube member to press the energy absorbing member and the outer tube member simultaneously in the crush direction to thereby crush them. The outer tube member formed in a shape in which tubular portions are coupled in the crush direction, and is crushed in the crush direction while the tubular portions are regularly folded when the outer tube member is pressed by the pressing member in the crush direction.

摘要： An energy absorbing member is fixed to a vehicle body. A joint has in a state where the longitudinal direction thereof extends along the front-back direction of the vehicle. Proximal and distal ends of the joint are respectively connected to the member and a bumper beam. The joint causes a collision load from the hamper beam to the vehicle body to act upon the member while collapsing in the longitudinal direction. A distal end has an inclined shape such that a distance from the member deceases gradually from the center toward the outside in the width direction of the vehicle. The distal end has a gradual increase region where a width in the height direction of the vehicle increases gradually and a gradual decrease region where the width in the height direction of the vehicle decreases gradually, from the center toward the outside in the width direction of the vehicle.
