Vehicular impact absorbing member

摘要

A vehicle shock absorbing member, which has a tubular shape having a plurality of flat plate-shaped sidewalls and having a closed section, in which, of the plurality of sidewalls, each of a pair of sidewalls located on right and left sides and separated from each other in a lateral direction of a vehicle has a groove portion formed extending in an axial direction of the tubular shape so as to be recessed inward, which is disposed between a vehicle body-side member and a bumper member in such an attitude that the axial direction corresponds to a longitudinal direction of the vehicle, and which, when subjected to a compressive load, is crushed like an a bellows in the axial direction to absorb impact energy, a pair of flat plate-shaped partition walls being formed in the tubular shape integrally with the tubular shape so as to be separated from each other in a vertical direction and so as to couple the pair of sidewalls, and the upper partition wall being tilted downward and the lower partition wall being tilted upward such that an interval between the pair of partition walls decreases closer to an inner side of the vehicle in the lateral direction of the vehicle.

1. A vehicle shock absorbing member, which has a tubular shape having a plurality of flat plate-shaped sidewalls and having a closed section, in which, of the plurality of sidewalls, each of a pair of sidewalls located on right and left sides and separated from each other in a lateral direction of a vehicle has a groove portion formed extending in an axial direction of the tubular shape so as to be recessed inward, which is disposed between a vehicle body-side member and a bumper member in such an attitude that the axial direction corresponds to a longitudinal direction of the vehicle, and which, when subjected to a compressive load, is crushed like a bellows in the axial direction to absorb impact energy,
a pair of flat plate-shaped partition walls being formed in the tubular shape integrally with the tubular shape so as to be separated from each other in a vertical direction and so as to couple the pair of sidewalls, and the upper partition wall being tilted downward and the lower partition wall being tilted upward such that an interval between the pair of partition walls decreases closer to an inner side of the vehicle in the lateral direction of the vehicle.
