Abstract: A door hinge for a vehicle door is provided with an integrated door check. One hinge member carries on its one end face a profile in the form of depressions, in which are inserted the retaining elements, e.g. in the form of balls, for a temporary arresting in predetermined positions. The balls are pressed down by a set of cup springs via a pressure plate or a ball bearing, so that there is a rolling movement of the retaining elements on the profile faces and on the pressure plate or ball bearing. The door check integrated into the door hinge is adjustable and/or readjustable with respect to its arresting force.
Abstract: The invention concerns a power-assisted lock for doors, hatches hoods or hard tops of vehicles and the like. In addition to a known pivotal latch and a catch for a releasable engagement with the pivotal latch there is a control disc pivotally mounted in the housing of the lock. A manual or power actuated drive means is attached to the control disc for the closing and opening operation. The pivotal latch and the control disc have a drive connection providing for limited play. The arrangement together with the catch leads to a locking of the control disc before a closing operation and an unlocking of the control disc by turning the pivotal latch during the closing operation of the lock. The pivotal latch has the usual pre-lock position.

Abstract: A tilting lever is mounted between a pivotal guide head and one side of a sliding door for a vehicle. The tilting lever is made of two angularly spaced arms with abutment surfaces at one end. The abutment surfaces engage with abutment surfaces and cam surfaces on the guide head and sliding door so as to hold the tilting lever in one of two positions. In one position the guide head is prevented from pivoting, while in the other position the sliding door is prevented from sliding. The guide head and sliding door are mounted together on a supporting arm pivoted to the body of the vehicle whereby the sliding door is first moved to an intermediate position and then to an open position.
Abstract: A supporting arm and a rod, each having one end pivoted to a guide head in which a sliding door for a vehicle is longitudinally movable and the other end pivoted to a vehicle body, are of equal length so as to form a parallelogram linkage. The pivots of the supporting arm and the rod are offset relative to each other, accordingly, when the sliding door is opened to an intermediate position parallel with the vehicle body, it will move perpendicularly to the vehicle body.
