Abstract: A spring device for the motion drive of a movable component from a rest position into a displaced position includes a gas spring and a preloaded spring, the movable component being loaded into the displaced position by a preloaded spring. The gas spring includes a pressurized gas-filled cylinder with a first end closed by a first end plate and a second end closed by a second end plate. A piston divides the interior of the cylinder into a first working chamber and a second working chamber. The piston having a first piston rod extending through the first working chamber and through the first end plate in a sealed manner, a free end of the first piston rod being fixed to the movable component or a stationary component, and a second piston rod extending through the second working chamber and through the second end plate in a sealed manner.

Abstract: A spring system has a first pulling part with a first fastening element connected by a tension spring to a second pulling part with a second fastening element. The pulling parts are moveable relative to one another so as to increase or relieve stressing on the tension spring. A damping device damps the movement of the pulling parts in relation to one another. A cylinder is fastened on the first pulling part and a piston 3 is axially displacesably arranged therein, subdividing the interior of the cylinder into a first cylinder chamber and a second cylinder chamber. A piston rod connected to the piston is arranged on the second pulling part. The interior of the cylinder is connected to the surroundings via one or more restrictor openings.

Abstract: Apparatus for the motorized opening and closing of a motor vehicle body part which can be pivoted with respect to a vehicle body about a hinged lid axis includes a guide cylinder having a first end and a second end which can be coupled to the body at a pivot axis which is parallel to the hinged lid axis, a piston guided displaceably in the cylinder, and a piston rod having one end attached to the piston and an opposite end which protrudes from the first end of the cylinder and can be coupled to the pivotable body part at a distance from the hinged lid axis. A drive device drives first and second Bowden cables, which extend in parallel from the second end of the cylinder, to displace the piston in the cylinder. The first Bowden cable includes a sheath which is supported on the piston and a core which is fixed to the first end of the cylinder. The second Bowden cable includes a sheath which is supported on the second end of the cylinder and a core which is fixed to the piston.

Abstract: A multi-joint hinge for a motor vehicle having a body and a panel, the hinge allowing the panel to be moved between an open position and a closed position relative to the vehicle body. The hinge includes at joint having at least one roller bearing, and is preferably a four bar joint having two bearings mounted on the body and two bearings mounted on the panel.
