A hood bumper protector is provided and consists of a bumper member which can be raised to an operative position by a hydraulic mechanism activated by the brake pedal to protect the hood and windshield of the motor vehicle from damage caused by a collision into another object such as a trailer truck.

A safety vehicle incorporating an impact member, a collision sensor and a safety device. When the vehicle collides with a typical pedestrian, he is struck by the impact member, which is so placed that it tends to make him fall onto a surface of the vehicle, e.g. the bonnet. The safety device, responding to the sensor, then moves from a stowed position to an operating position in which it restrains him from falling off the surface again. The stowed location of the device and its path of movement to its operating position are chosen so that it does not impede, but may actually assist, the movement of the pedestrian onto the bonnet.

A safety device for the protection of pedestrians involved in a collision with a vehicle is arranged in the zone of the front hood of the vehicle. The safety device is in the form of a mechanism for raising the rear of the front hood, which mechanism can be triggered by a sensor installation arranged in the zone of the front bumper of the vehicle for detection of a collision with the pedestrian. Upon detection of a collision, the mechanism raises the front hood from a rest position to an impact position in which the potential for contact between the pedestrian's head and the windshield are reduced.

A device for reducing impact to a pedestrian involved in a collision with a motor vehicle includes a displacement mechanism to raise a hood from a rest position to an impact position elevated relative to the rest position, and an air bag module including an air bag. The air bag module is operative to inflate the air bag after displacement of the hood from the rest position to the impact position has begun. When inflated, the air bag has its first cushion portion extending beneath the hood and its second cushion portion extending out from the rear of the hood. The second cushion portion extends over a lower portion of a windshield of the vehicle.

This invention relates to a pedestrian protection device for motor vehicles which comprises essentially a hinged member adapted to be raised to an operative position from a normally lower inoperative position on the motor vehicle. More particularly, this hinged member constitutes a kind of transverse beam or barrier having side flanges provided with two series of connecting means associated with a pair of trunnions permitting the rotation of said beam and secured to said side flanges. The second series of connecting means provides an operative connection between the beam and the thrust rod of a cylinder and piston unit having its cylinder pivoted to the vehicle body. The essential purpose of this device is to protect pedestrians against the dangers of running into a car.
