  • BUMPER STRUCTURE
    Publication number: 20110012381
    Abstract: A lightweight bumper structure is achieved without a reduction in the amount of absorption of collision energy. A bumper structure (B1) is provided with a left and right pair of bumper stays (1, 1) fixed to side members (S), and also with a bumper reinforcing member (2) supported by both the bumper stays (1, 1). Each bumper stay (1) is formed in a shape the width of which gradually increases from the side member (S) toward the bumper reinforcing member (2). The bumper reinforcing member (2) is curved between both the bumper stays (1, 1). The rigidity of the bumper stays (1) and the bumper reinforcing member (2) is set so that the bumper stays (1) are crushed in the front-rear direction after the curved portion of the bumper reinforcing member (2) is rectilinearly extended.
