A vehicle door check mechanism includes a bellows to act as a pneumatic retarder to prevent a high load from being transferred from the door check mechanism to a structural part of a door of the motor vehicle if that door is opened to a fully open position at high speed.

A composite vibration-damping body including a first elastic body and a second elastic body overlapped with each other, wherein the first elastic body is formed of a material having higher attenuation than that of the second elastic body, the first elastic body includes a recessed part opening onto a surface of the first elastic body, and the recessed part forms a gap, and a strain concentration part configured to be subjected to an increased strain during load input is set to a wall of the gap of the of the first elastic body.

A door component has a controllable damper device that contains a magnetorheological fluid as a working fluid. Two connection units of the damper device can be moved relative to each other. One of the two connection units can be connected to a support structure, and the other connection unit can be connected to a pivotal door device in order to damp a movement of the door device between a closed position and an open position in a controlled manner. The magnetorheological damper device has a piston unit and a cylinder unit which surrounds the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit has a first piston rod, which extends through the first chamber, and a second piston rod, which extends through the second chamber.

A vehicle, such as a pickup truck, includes a bed pillar and a tailgate pivotally engaging the bed pillar. A bumper includes a body secured to the bed pillar, a lever pivotally mounted to the body and having a pad, and a spring biasing the pad into contact with the tailgate in a closed position. The lever may pivot to push the tailgate rearward.

A rotary hinge assembly includes a fluid chamber filled with a fluid and a constricted section with a throat area which is tunable by a throat tuner to control the fluid flow passing through the constricted section. Within the fluid chamber, a rotary connecting pin is mounted so that a first longitudinal end of the pin is connected to a door, and a second longitudinal end of the pin is concentrically and rotatably mounted within the fluid chamber. On the second longitudinal end, a vane is connected and adapted to rotate for displacing the fluid present in the fluid chamber towards the constricted section, when the rotary connecting pin undergoes the rotational movement in response to opening and closing of the door.

A motor vehicle lock for a movable vehicle part, in particular for a door, flap, tailgate, or bonnet, said lock having a lock housing and a rotary latch that is movably provided on the lock housing, and the rotary latch being movable into an open position and at least one engaged position. In addition, at least on buffer unit is provided on the lock housing and at least on braking element is located on the buffer unit, such that at least some portions of the braking element can be brought into contact with the rotary latch, at least while the rotary latch is moving into the open position.

A door drive device for adjusting and/or locking a vehicle door relative to a vehicle body including an adjustment member, a drive element operatively coupled to the adjustment member such that the adjustment member is movable with respect to the drive element for moving the vehicle door, a sensor device for measuring a measuring quantity indicative of a movement of the vehicle door to provide a sensor signal, a brake device operatively connected to the drive element for braking a movement of the vehicle door, and a control device for controlling operation of the door drive device. The control device is configured to compute, from the sensor signal obtained from the sensor device, an acceleration value indicative of an acceleration of the vehicle door and evaluate the acceleration value to distinguish movement of the vehicle door caused by a gravity force from movement caused by a user action.

A vehicle includes at least one vehicle door or vehicle flap which forms a first body, a vehicle bodyshell which forms a second body, and an impact damper arrangement. The impact damper arrangement is configured such that, when the vehicle door or vehicle flap moves toward the vehicle bodyshell, a first movement section is passed through first, and then a second movement section is passed through. The first movement section is arranged such that movement along the first movement section comes to an end when a lock and closing element come into contact with one another.

An adjustable stopper device (1) for a vehicle door or hood, includes a base part (100), and adjustment part (200), a stopper part (300) and a fastening structure (400). The adjustment part is connected to the base part via threads (120, 220) and thereby rotatable around a device axis (210) with respect to the base part (100). The stopper part is configured to contact the vehicle door and to provide an abutment surface (310) for the vehicle door when the vehicle door is closed, wherein the stopper part is connected to the adjustment part and wherein the axial position of the abutment surface is adjustable by turning the adjustment part with respect to the base part around the device axis. The fastening structure fastens the base part to the car body (2). A vehicle with, use of and method for manufacturing such a device are also described.

A device for adjusting an elevation of a piece comprises a body and a pin. The body is intended to be secured to a support, and has an internal surface defining a central cylinder provided with an internal thread and having a first opening. The pin has an external thread, a first end for carrying the piece, and a second end. The pin and the body are connected to one other through their respective threads. The pin can, when rotated, move in a longitudinal direction to adjust the elevation of its first end. The pin has at least two longitudinal slots on its second end to define at least two flexible legs. The body has at least one boss on its internal surface configured to bend the flexible legs and to fit into one of the slots during the rotational movement of the pin so as to index an elevational position of the piece.
