The holding-open device has a multiple, ie. four or more, coupling drive in the region between the external longitudinal bearer (2) and the running rail (1). An adjusting element (7) is fitted to its coupling plate (6). This coupling plate can turn on a supporting hinge (10) via two links (8,9). The other end of the coupling plate is linked to a crank (4) via an actuating shaft (3). The crank is in the form of a one-arm or two-arm lever, the end of which carries the adjusting element. The coupling plate roller corresponds to the guide track. |
