IPC: B60R22/46

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 system for actively attenuating acoustic vibrations of a rail for rail traffic is provided including at least one sensor for detecting at least a vertical acoustic vibration of the rail, at least one actuator for exciting at least a vertical counter-vibration of the rail and at least one control unit communicatively connected to the at least one sensor and the at least one actuator for controlling the at least one actuator depending on the vibration detected by the sensor, the counter-vibration being adapted to destructively interfere with the detected vibration, and the at least one actuator being mechanically coupled to the rail and to a carrier element supporting the rail. Also provided is a carrier element for the system and a method for actively attenuating acoustic vibrations of a rail for rail traffic.

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.
