855,619. Doors for passenger vehicles DAIMLER-BENZ A.G. March 16, 1959 [March 15, 1958], No. 9067/59. Class 103(2). A motor vehicle door 3, Figs. 1 and 2, is carried by a T-shaped bearing arm 6 provided with rollers 5, engaging in a guide rail 4 on the door, and pivoted in bearings 7 in a vehicle chassis member 2, the arrangement being such that to open the door it is moved transversely of the vehicle body 1 into an intermediate position, shown in Fig. 1, and thereafter slid lengthwise of the vehicle. A resilient seal is provided between the door and the body. Instead of being pivotal in bearings 7 the door may be carried by a link parallelogram whereby it remains parallel to the door opening, as described with reference to Fig. 3 (not shown), In this case the bearing arm is carried by the link parallelogram and is provided with a handle and operating button to lock the parallelogram against rocking movement. The bearing arm at its lower end may be connected to a spindle slidable in bearings 7 in either direction against the action of springs mounting the spindle; in this case the bearing arm is arranged centrally with respect to the door opening. Alternatively the bearing arm at its lower end may slide on a spindle between bearings 7 against the action of springs. In this case the rollers 5 are carried on a cross-piece slidable in either direction relative to the bearing arm against the action of springs. In a further embodiment the crosspiece for the rollers 5 is pivotally connected to the upper ends of two struts pivoted at their lower ends to a spindle pivotal in bearings 7 whereby the door may also pivot in the lengthwise direction of the vehicle. In a still further embodiment the roller cross-piece is pivotal about a generally vertical axis in a lower part of the bearing arm, which in turn has rollers thereon slidable in a guide rail pivoted in bearings 7, as described with reference to Fig. 7 (not shown). The door may be fully or partly automatically controlled from the vehicle instrument panel. An electric motor may be employed to effect the sliding movement only or separate motors may be provided for the transverse and sliding movements. |
