Abstract: A spindle drive for a motorized adjustment of an adjustment element of a motor vehicle includes a tubular or half-shell-like spindle drive housing. An annular or disk-like connection portion is inserted and secured in one end region of the spindle drive housing. The annular or disk-like connection portion is connected via a damping element comprising a resilient damping material to a connection for discharging axial drive movements. The connection portion has a coaxial recess with an inner radially peripheral wall having a radially peripheral groove. The connection with the end region thereof facing the spindle drive housing protrudes axially into the recess of the connection portion and has a radially peripheral flange which protrudes radially into the groove. The damping element is arranged in a gap disposed between the side walls of the groove and the side walls of the flange.

Abstract: Provided is a brake device for braking a rotational movement of a shaft about the longitudinal axis, wherein the shaft is mounted so as to be rotatable about the longitudinal axis in a direction of rotation and in a counter direction which opposes the direction of rotation. Brake devices typically use constant and relatively high braking torques, to ensure a controlled movement of a movement portion, braked by the brake device, in every situation. However, this increases the energy consumption for a movement of the movement portion, and the wear of the brake device. A brake device equipped with a setting device for mutually opposing setting of a braking torque on the shaft during rotation of the shaft in the direction of rotation, and a counter braking torque during rotation of the shaft in the counter direction is provided. Also provided is a method for controlling a brake device.

Abstract: A piston assembly for use in a gas spring or damper can include a piston rod partially positioned within a pressure tube, and a linear position sensing apparatus capable of tracking and determining the velocity of the piston rod. The linear position sensing apparatus can include a sensor, such as a waveguide sensor, connected to the piston rod such that the sensor moves with the piston rod. A beacon, such as a magnet, can be contained within the pressure tube and the sensor can detect the position of the beacon relative to the sensor.

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: Provided is a drive device for the movement of a closure element of a motor vehicle relative to a body of the motor vehicle including an outer tube with a longitudinal axis for coupling to the body, an inner element arranged in the outer tube for coupling to the closure element, a helical compression spring arranged between the inner element and the outer tube, and an internal guide element arranged between the inner element and the helical compression spring and axially fixed to the inner element for the internal guidance of an internal guide end section of the helical compression spring. The inner element is extendable along the longitudinal axis from the outer tube. The helical compression spring is compressed against a spring tension of the helical compression spring when the inner element is pulled out of the outer tube.

Abstract: A piston and a method for producing a piston which can be secured to a piston sliding unit is provided. The piston sliding unit can be moved along its longitudinal axis in a cylinder. The piston includes a disc-shaped base body, wherein the piston is suitable and intended to seal two regions of the cylinder filled with a medium against one another. The method includes the following steps: a) producing the piston by pressing a material into a piston mold; b) smoothing the surface of the piston and/or pressing at least one flow path into the piston, by an embossing tool, which has a raised and rotationally symmetrical structure.
