Abstract: The present disclosure relates to a motor vehicle, comprising a leaf element, which is movably held at a bearing point of the motor vehicle, and an adjusting device by means of which the leaf element can be moved between a closed position, in which the leaf element closes an opening of the motor vehicle, and an open position, wherein the adjusting device comprises a spring component which, on the one hand, is coupled at least indirectly to the leaf element and, on the other hand, at least indirectly to a holding region of the motor vehicle, and which comprises a sleeve element and a piston element which is inserted into a sleeve interior of the sleeve element in certain regions and is displaceable relative to the sleeve element during the movement of the leaf element between the closed position and the open position.

Abstract: Disclosed is an adjusting device for raising a hinged lid from a lowered, closed position into a raised, open position, especially for a motor vehicle, with a cylinder closed at one end, a piston, which divides the interior space of the cylinder into a first working chamber and a second working chamber, and which is installed with freedom to move axially back and forth in the cylinder, a piston rod, attached to the piston, the rod extending axially through the first working chamber and projecting through a seal to the outside, one or more flow connections connecting the first working chamber to the second working chamber, and a first adjusting element and a second adjusting element, wherein the first and second adjusting elements are designed to telescope into and out of each other and have guide devices, which make it possible to open the hinged lid into a partially opened position or into a completely opened position.

Abstract: The invention relates to a gas spring with end position damping having a piston-cylinder unit which is provided with two identically configured pistons arranged in a mirror-like image. Each piston has two axially extending parts defining an annular groove therebetween. The groove is configured to receive an annular sealing ring operative to axially move within the groove. The groove, the pistons and cylinder are configured with an arrangement of flow passages providing damping at the end of the push-in and push-out strokes of the piston.
