Claim Text:
1. An actuation device for selecting gear settings of a shift-by-wire gear shifting transmission, the actuation device comprising: an actuation element that can move along a shifting path between a parking brake setting and a driving gear setting, a mechanical transference device for mechanically actuating the parking brake, and a coupling device disposed between the actuation element and the mechanical transference device, wherein the coupling device is configured for the selective actuation of the mechanical transference device only when the actuation element moves into or out of the parking brake setting, wherein the coupling device comprises a substantially prismatic bearing guide having a notch and a two-part coupling carriage supported in a displaceable manner along the bearing guide, the two-part coupling carriage comprising an actuation-side carriage part and a transference-device-side carriage part, wherein the actuation-side carriage part and the transference-device-side carriage part overlap one another in the coupled position at an overlap section in an axial plane of the bearing guide, wherein a locking element is disposed in the transference-device-side carriage part in the overlapping section, at a right angle to the bearing guide, supported in a moveable manner, and spaced apart from the bearing guide and the notch, wherein the locking element can move perpendicular to the bearing guide between a first relative position and a non-self-limiting second relative position, wherein when the locking element is in the first relative position, the actuation-side carriage part and the transference-device-side carriage part are coupled together by an engagement of the locking element in both parts of the two-part coupling carriage and when the locking element is in the non-self-limiting second relative position, by moving the two-part coupling carriage along the bearing guide so that the locking element is over the notch, the engagement of the locking element with the actuation-side carriage part is released.
