Patent ID: 8464601

Claim:
An actuating device for selecting shift steps of a gearshift transmission, the actuating device comprising: a selector lever ( 1 ) that is movable between two drive-setting positions, and a locking mechanism for restricting a range of movement of the selector lever ( 1 ) and locking certain drive-setting positions and for locking the selector lever ( 1 ), wherein the locking mechanism comprises a locking body that defines a locking recess ( 2 ) and is fixedly connected to the selector lever ( 1 ) so as to prevent relative movement of the locking recess with respect to the selector lever, a substantially prismatic locking cam ( 5 , 17 ) that is actuated to rotate about a rotational axis parallel to a longitudinal axis of the locking cam ( 5 , 17 ) such that the locking cam ( 5 , 17 ) engages the locking body in at least two positions in the locking recess ( 2 ) to restrict movement of the selector lever in opposite directions, the prismatic locking cam being rotatable between different rotational locking positions and each of the different rotational locking positions of the prismatic locking cam defines a distinct range of movement of the selector lever.
