摘要： A pedestrian safety device for mounting to an automotive vehicle has a relatively low-resistance mechanical response when struck by an object having the approximate width of a human leg, and relatively high-resistance response when struck by an object wider than a human leg. The impact energy management device comprises a backplate attachable the vehicle and a plurality of seesaw elements attached to the backplate for pivoting movement relative to the backplate. Each element has a first and a second contact end spaced forwardly from the beam. When a narrow object like a pedestrian's leg strikes the device, only one end of each seesaw element is urged toward the backplate and the element pivots with respect to the backplate to absorb energy and offer a relatively low resistance. When a wider object strikes the device, both contact ends of a seesaw element are engaged so that the element bends toward the backplate. The strain caused by the bending offering a higher resistance to intrusion by the object.

摘要： An engine hood for motor vehicles possesses a deformable head impact zone for the protection of pedestrians in the event of a collision with the motor vehicle. The engine hood is composed of two or more load-bearing shells and has a flexural strength profile which is low adjacent the edges and increases continuously toward the middle of the hood. At the same time, the engine hood has a uniform mass distribution ovcr the entire surface. Consequently, irrespective of the position the engine hood, the same characteristic for the head impact is achieved everywhere. The advantageous embodiment of the engine hood provides a reinforcing panel with regularly arranged beads, at most three beads forming a junction point so as to reduce local rigidities.
