The central-locking system for the locking elements (11.1 to 11.5) of vehicle doors of a vehicle and, if appropriate, of other closing lids of vehicle apertures or the like is wired in such a way that, when the driver's door lock (17) is actuated in the direction of locking engagement, all the locking elements are loaded by the energy of the dual-pressure pump (15) in the closing direction. For opening the locking elements, two different switching possibilities are provided. These are determined by the selector switch (21) to be arranged near the driver. Irrespective of its position, the locking element (11.1) assigned to the driver's door (F) is always connected to the dual-pressure pump (15) via the pneumatic line (12.1). The locking elements (11.2 to 11.5) assigned to further doors or to other apertures or devices to be closed can be connected in parallel with the feedline (12.1) for the opening operation leading to the driver's door, in particular when the selector switch (21) has been closed before the vehicle is left and when the magnet (20.3) keeps the switching valve (20.1) opened. A purely electrical circuit can be constructed in an equivalent way by a corresponding division into two pole-reversible circuits and corresponding connection to a selector switch, in order to form the central-locking system having an unlocking stop. <IMAGE> |
