The invention provides a structure of a front part of a vehicle body that is simple and free from the risk of maloperation. In the event of a collision between the vehicle and a pedestrian, a projecting part sweeps the pedestrian by parts of his or her legs lower than the knees in the event of a collision between the vehicle and the pedestrian, causing the pedestrian to be thrown over toward the vehicle, and after an energy-absorbing member has absorbed impact energy exerted on the legs, the pedestrian is caused to drop onto the top of a hood and protected from secondary damage. In one specific example, a structure of a front part of a vehicle body in which a bumper (9) is provided at a lower front position of a hood (1) of the vehicle comprises a lateral supporting member (7) provided in the front part of the vehicle body and extending in the direction of vehicle width, an energy-absorbing member (8) provided ahead of the lateral supporting member (7), and a projecting part (12) provided at a lower part of the bumper 9 in such a manner that a forward end of the projecting part (12) juts out more frontward than the lateral supporting member (7).

Main water valves are remotely actuated by air to release high pressure water to corresponding sets of nozzles. A pressure control valve controls the pressure of water supplied to the main water valves from a positive displacement, high pressure water pump.

Device for motor vehicles designed to prevent traffic accidents or to reduce their injurious consequences. The extent of injuries in traffic accidents can be reduced significantly by employing the vehicle bumper (1) as a crumple (deformation) zone. A sensor (2) is used to record this distance from and speed relative to an obstacle in the direction of travel. When a collision is unavoidable, one end of the bumper (1) is projected outward by a propellant charge (13) so that, together with a strut (17, 22, 24), if forms a crumple zone ahead of the vehicle. The device can also be provided with a system to warn of dangerous traffic situations, and to brake the vehicle automatically or reduce its speed if the risk of a collision exists. In the case of trucks and buses, the bumper (1) may be deployed by means of a pneumatic cylinder (4) and valve (7), which are controlled by the vehicle's ordinary speedometer.
