Abstract
In a vehicle bumper structure, an optical fiber sensor (32) is provided in a vehicle width direction on the front surface of a front-bumper reinforcement (30). A front-bumper absorber (28) is provided in front of the optical fiber sensor (32), the front-bumper absorber (28) formed of a soft absorber (54) and a hard absorber (56). The hard absorber is disposed at the bumper center region where the thickness of the bumper is increased. Accordingly, the thickness of the soft absorber (54) becomes substantially uniform in the vehicle width direction, so that a substantially uniform load is inputted to the optical fiber sensor (32) regardless of the collision position of the bumper with an object. As a result, variations in the output of the load-sensing unit are reduced.
