Abstract: A fluid damper for modulating a retaining force of a seat belt is provided. The fluid damper includes an outer cylinder and an inner cylinder. The inner cylinder encloses an inner space. The fluid damper includes a piston shiftable in the inner space. The fluid damper includes a duct. The duct conductively connects a front fluid chamber disposed in front of the piston to a rear fluid chamber disposed behind the piston and/or a reservoir for the damping fluid. The duct includes an outer duct portion and an inner duct portion. The inner cylinder is deflectable from a rest position by a force acting on the piston so that the deflection of the inner cylinder causes an adjustment of an overlap of the outer duct portion and the inner duct portion depending on the magnitude of the force.

Abstract: A self-regulating damper unit comprising a cylinder having a first working chamber and a second working chamber, a piston, a piston rod, and a through-hole between the first working chamber and the second working chamber. The damper unit also comprises a shiftable weight which modifies a passage cross-section of the through-hole. The shiftable weight is movably mounted such that retardation of the piston causes enlargement of the passage cross-section. A seat belt unit comprises a seat belt and the damper unit.

Abstract: A rail brake damper includes a cylinder-piston arrangement. A damping device assigned to the piston comprises at least one damping valve having at least one piston channel, which passes through the piston, connecting the two operating chambers of the cylinder, and a closure element assigned to the piston channel. The closure element is spring pre-loaded with the effect of closing the piston channel and is acted on by the hydraulic pressure which prevails in the operating chamber facing away from the piston rod with the effect of opening the damping valve.

Abstract: A piston-cylinder assembly includes a cylinder having a cylinder interior filled with a fluid and divided by a piston, which is axially displaceable in cylinder, into a first working space and a second working space. A piston rod is arranged on piston and is guided through second working space and through an end-side second closure in a manner sealed off to the outside at the second end of the cylinder. The retraction stroke of piston and piston rod is restricted by a stop which is arranged in cylinder and against which piston comes to bear directly or indirectly, wherein the axial position of the stop in cylinder is variably adjustable by an adjustment device.
