A damping assembly for a flap fitting includes first and second spring holders, between which at least two coil springs are arranged. In each of the at least two coils springs, a linear damper having a damper housing and having a piston rod slidable relative to the damper housing is arranged between the first and second spring holders.

A door system includes a door having a housing mounted in the bottom edge of the door that retains a bottom seal and a second channel for receiving a guide. A seal is formed adjacent the periphery of the door between the door and a door opening in a structure when the door is in the closed position. The seal includes deformable gaskets that extend between the structure and the door to form a seal around the door opening. A first soft close device is mounted adjacent the open positon and a second soft close device is mounted adjacent the closed position. A single activator pin is mounted on the door and positioned such that the activator pin engages the first soft close device as the door nears the open positon and engages the second soft close device as the door nears the closed position.

A drive apparatus for a closure element of a motor vehicle, including a tube defining an axis, a spindle disposed within the tube and configured to translate along the axis from an extended position to a first retracted position and a second retracted position, a spindle nut disposed within the tube and operatively engaged to the spindle, a stop nut fixed to the spindle, and a damping element disposed between the spindle nut and the stop nut. The tube defines a first end stop face and the stop nut defines a second end stop face, and when the spindle is in the first retracted position, the damping element engages the first end stop face and is spaced apart from the stop nut.

The invention relates to a sliding door fitting comprising a carriage, which is guided on a guide rail and which is connected to a housing of a retraction device in an articulated manner, wherein the retraction device has at least one, preferably two driver elements, which can be moved along guide tracks and which are spaced apart, the one or more driver elements being preloaded into a retraction position by means of at least one force accumulator, wherein the housing of the retraction device is preloaded in a direction rotation relative to the carriage.

A damping device includes a housing, a piston and a controller. The housing defines a chamber filled with a damping medium. The piston is movable in the chamber and includes a passage for allowing the damping medium to pass through. The controller includes a control member and a resilient member. The control member is capable of being moved toward the passage of the piston or closing a portion or all portions of the passage of the piston in response to a speed of the piston.

A damping device includes a housing and a piston. The housing has an inner wall, and a chamber is defined by the inner wall. The chamber has a damping medium filled therewith. The piston is movable in the chamber, wherein the inner wall has a plurality of inner diameters.

An exemplary closure assembly includes a rail assembly and a door assembly movably mounted to the rail assembly. The door assembly includes a rotary damper having a pinion, and the rail assembly includes a rack member operable to engage the pinion. As the door moves from first position to a second position, the rack member engages the pinion, thereby causing the pinion to rotate in a first rotational direction. The rotary damper resists rotation of the pinion in the first direction, thereby slowing movement of the door toward the second position. The rotary damper may be a one-way damper that does not resist rotation of the pinion in a second rotational direction such that the rotary damper does not resist movement of the door from the second position toward the first position.

A door hinge device comprises a hinge base and an auxiliary door-closing mechanism mounted on a door and fitted with the hinge base. The auxiliary door-closing mechanism comprises a shell, an elastic member for driving the door to be automatically closed during the door closing process, a sliding member, and a guiding member for guiding the sliding member to move in the deformation direction of the elastic member during the door opening and closing process. One end of the elastic member is connected to the shell, an accommodating part for accommodating the sliding member when the door is in a closed state and a guiding bevel obliquely extending forwards to approach the auxiliary door-closing mechanism are arranged on the periphery of the hinge base in a concave manner, and the sliding member is in a compressed state when moving along the guiding bevel.

A device is provided for controlling the motion of a movable member such as a sliding door. The device comprises two springs. Each spring has its own catch for releasably holding it in a pre-loaded condition. The catches are releasable by motion of the door to apply force to its closing movement. The catches are arranged so that one of the springs will exert force on the door before the other.

A bidirectional damper includes a box body, a damping cylinder arranged in the box body, a spring assembly, and two sliding blocks. The damping cylinder and the spring assembly are parallelly arranged between two sliding blocks, and ends of the damping cylinder and the spring assembly pivots with corresponding sliding block. Sliding pins are arranged on sides of the two sliding blocks, and a first blocking portion and a second blocking portion are arranged on lower ends of the two sliding blocks. Sliding grooves are arranged on sides of the box body and extends along two ends of the box body, and the sliding grooves are correspondingly matched with the sliding pins on the two sliding blocks. An end of the sliding grooves, near an end of the box body, is bent towards a top of the box body.
