A system for adjusting a vehicle door relative to a vehicle body including an adjusting device, a control device for controlling the adjusting device. The control device is configured to receive an operating command and control the adjusting device based on receiving the operating command, and a sensor device for detecting an object. The control device is configured to evaluate for the purpose of collision protection monitoring whether an operating command is received in a near area relative to the vehicle door via an operating device. For collision protection monitoring, the control device is configured to use a first recognition area in a first operating mode upon receiving an operating command via an operating device in the near area, and in a second operating mode to use a second recognition area different from the first recognition area when an operating command is not received in the near area.

A door drive mechanism includes a main drive and an auxiliary drive.

In this connection it is provided that the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output and that the drive assembly of the auxiliary drive is borne in a pivot bearing and that the rod system is formed as a slide arm and the rod system bearing is formed as a slide rail.

An apparatus is provided for minimizing closing force of a door. The apparatus comprises a housing adapted to be disposed in the hinged edge of the door. A piston is slidably mounted in the bore. A button having an inner end and an outer end is disposed in the bore with the inner end of the button engaging the piston for urging the button toward a first extended position where the button extends from the edge of the door. The button is slidable in the bore relative to the housing for reciprocal movement between the extended position and a second position where the button is depressed into the bore against the force of the piston. The button is disposed so that the outer end of the button engages the door frame for slowing movement of the door in a closing direction as the button is moved into the bore to the depressed second position.

A door drive mechanism includes a main drive and an auxiliary drive.

In this connection it is provided that the components of the main drive and of the auxiliary drive to be mounted on the door leaf side are borne in or on a common and/or continuous housing mechanism and/or bearing framework mechanism and/or mounting plate mechanism to be mounted on the door leaf side and/or are covered by a common and/or continuous cover to be mounted on the door leaf side.

The disclosure relates to a drive arrangement for a flap of a motor vehicle, comprising a linear drive for producing drive movements and comprising a transmission arrangement, which is coupled to said linear drive, for transmitting the drive movements, a compensating arrangement being provided which couples two drive elements of the drive arrangement to each other in terms of drive, and, when a limit load between the two drive elements is exceeded, the compensating arrangement permitting a guided compensating movement between the two drive elements. It is proposed that the transmission arrangement provides the compensating arrangement.

Some embodiments of the disclosed subject matter are directed to a vehicle door that includes a door frame and a door trim with pinch sensor located adjacent the door frame. A door harness coupler can hang within the door frame prior to assembly of the door, and can be connected to a pinch sensor coupler adjacent the door trim to electrically connect the pinch sensor to a controller and/or door actuator. Thus, the pinch sensor can be installed at the end of a door assembly line.

An emergency bi-fold door closing prevention system includes a building having an access opening with an upper edge. A bi-fold door is hingedly mounted to the building wall and includes a plurality of panels each being laterally elongated. The plurality of panels includes a bottom panel having a bottom edge that is positionable adjacent to a floor surface to define a closed position. A safety line assembly is attached to and extends between the building wall adjacent to the upper edge and the bi-fold door adjacent to the bottom edge. The safety line has an extendable length. The length of the safety line assembly extends when the bi-fold door moves toward the closed position below a threshold velocity. The length of the safety line assembly is inhibited from extending when the bi-fold door moves toward the closed position above the threshold velocity to prevent unimpeded falling of the bi-fold door.

A thermally releasable fastening element, in particular for fastening a door actuator, includes a base body, which is designed to be inserted into a recess or a number of aligned recesses, a core inserted into the base body, at least partially made of a shape memory material, wherein the base body has an unstable area, which is stabilized by the core, and wherein the core is designed to withdraw at least partially from the unstable area upon thermal activation of the shape memory material.
