  • Patent number: 6913126
    Abstract: An impact damper for deceleration of a vehicle impacting on all obstacle by hydraulic damping forces and gas spring forces includes at least inner and outer pipes telescopically displaceable one inside the other and defining an annular space therebetween with a base closing one end of the inner pipe. A dividing piston is sealingly guided in the inner pipe. The inner pipe, the base, and the dividing piston define a gas space which holds gas under pressure. The inner pipe further defines a first liquid space separated from the gas space by the dividing piston. An intermediate wall is fastened to the inner pipe and includes a throttle opening therethrough connecting a second liquid space to the first liquid space. The annular space between the first and second pipes has one end sealed to the atmosphere and another end sealed by the intermediate wall.

  • Patent number: 6669179
    Abstract: Impact damper as a connecting member between a bumper and a chassis of a motor vehicle for the purpose of damping the shock loading during a collision between this motor vehicle and an obstacle, predominantly through gas-spring forces and deformation work. This impact damper includes an inner tube and an outer tube, which can be displaced telescopically one inside the other, thereby changing the volume of pressurized first and second gas spaces, at least one of the gas spaces being connected to an accumulator by a pneumatic feed line. An electrically controllable control valve, by means of which the air pressure in the gas spaces can be changed, can be arranged in the pneumatic feed line. The pressure in the gas spaces can be varied by a detection sensor system in the motor vehicle, which controls a control valve and adapts the pressure to the expected momentum of the collision. It is possible for a deformation element to be displaced as well to absorb a high impact energy by deformation work.

  • Patent number: 6659535
    Abstract: An impact damper as a connecting member between a bumper and a chassis of a motor vehicle for the purpose of damping the shock loading during a collision between this motor vehicle and an obstacle, predominantly through deformation work in a tube of the impact damper. The tube is connected to the chassis via a bracket and to the bumper via a bumper receptacle. The bumper receptacle, the bracket and the towing lug with the tube are connected to one another by a joining technique before they are connected to one another by a stamping operation. The advantage of the invention lies in low-cost production without compromises in terms of the functioning of the impact damper.

    Abstract: An impact damper as a connecting member between a bumper and a chassis of a motor vehicle for the purpose of damping the shock loading during a collision between this motor vehicle and an obstacle through hydraulic damping forces and gas-spring forces. This impact damper includes an inner tube which can be displaced telescopically inside an outer tube, thereby changing the volume of a pressurized gas space, which interact by means of a separating piston with a first liquid space, which communicates hydraulically via a restriction orifice with a second liquid space, which is bounded by a deformation element. The separating piston is arranged in a floating manner in the inner tube and thereby brings about a static equilibrium by pressure compensation in the liquid spaces and in the gas space.

  • Publication number: 20030020289
    Abstract: An impact protector for motor vehicles, comprising a bumper on at least one connecting part for connection to a chassis of the motor vehicle and an elastomeric impact strip along the bumper to dissipate impact energy in the event of a collision between the motor vehicle and an obstacle. The elastomeric impact strip includes an air hose, which can be filled with air, and a cover, the air hose being connected to an accumulator by a pressure line to form an air cushion. The air pressure in the air hose is controllable by means of a valve, which is connected by an electronic control line to a detection sensor system for detection of the magnitude of the impact to be cushioned immediately before the collision of the motor vehicle, in particular with pedestrians.
