  • Patent number: 5226303
    Abstract: A locking arrangement between a selector lever of a transmission and an ignition lock of a motor vehicle has a locking pawl, which is rotatably disposed in a selector lever block. The locking pawl, via a recess, form-lockingly reaches around a cam part arranged on the selector lever. When the selector lever is in the parking position, the cam part is rigidly connected with a button that is to be operated manually. In this case, a catch hook of the locking pawl engages into the moving path of a locking cam, which is arranged on the selector-lever-side end of a flexible linkage. The catch hook acts in a blocking manner, as long as the button is operated into a first position. When the button is not operated, the ignition lock, which by way of the linkage is connected with the locking cam, can be rotated into an inoperative position, whereby the locking cam fixes the locking pawl. The button cannot then be operated because the cam part is fixed by the recess.

  • Patent number: 5218847
    Abstract: A locking arrangement between an ignition lock and the selector lever of an automatic motor vehicle transmission has a locking slide arranged on the selector-lever side which, via a control ramp, displaces a locking bolt into a position blocking locking pin. This blocking position can only be achieved when the selector lever with the inoperative button is in the parking position and an ignition key has been rotated into an inoperative position. When the ignition key is pulled out, the selector lever cannot move out of the parking position, thereby preventing an accidental engaging, for example, in a neutral position.
