  "abstract": "An ignition lock is provided for a driving authorization system in a motor vehicle that interacts for authentication purposes with an electronic key or the like via an encoded operating signal. The ignition lock contains a moving element that can move from a starting position into at least one actuating position of a switching element. The moving element has a switching effect on the switching element in the actuating position. The ignition lock includes a lever that can be inserted into the moving element for manually moving the moving element. A locking feature interacts with the lever in the inserted state so that the removal of the lever from the moving element is blocked. The lever contains an actuating element for the release of the locking feature so that upon actuation of the actuating element the lever can be removed from the moving element.",

    "1. Ignition lock, in particular for a driving authorization system in a motor vehicle that interacts for authentication purposes with an electronic key, a chip card, an identification (ID) sensor or the like, with a switching element (3), a moving element (2) that can move from a starting position (21) into at least one actuating position (22, 23, 24), wherein the moving element (2) has a switching effect on the control element (3) in the actuating position (22, 23, 24), and a lever (4) that can be inserted into the moving element (2) for the manual movement of the moving element (2), characterized in that a locking feature (5) interacts with the lever (4) in the inserted state so that the removal of the lever (4) from the moving element (2) is blocked, and the lever (4) contains an actuating element (6) for the release of the locking feature (5), so that upon actuation of the actuating element (6), the lever (4) can be removed from the moving element (2). 2. Ignition lock pursuant to claim 1, characterized in that the moving element (2) is designed as a kind of rotor so that the rotor (2) can be rotated from the starting position (21) into the actuating position (22, 23, 24) via the lever (4), in the actuating position (22, 23, 24) preferably an elastic force, especially a spring force, acts upon the rotor (2) so that the rotor (2) automatically returns to the starting position (21) when the manual actuation on the lever (4) stops, and furthermore, preferably proceeding from the starting position (21) in the one direction of rotation initially in a first actuating position (22), the ignition of the motor is switched on, in a subsequent second actuating position (23) the motor is started and, proceeding from the starting position (21) in the other direction of rotation in a third actuating position (24), the ignition of the motor is switched off. 3. Ignition lock pursuant to claim 1 or 2, characterized in that the lever (4) is designed in the form of an ignition key with a key bit (7) and a grip part (8), the moving element (2) preferably contains a holding feature (20) into which the key bit (7), which serves for the insertion of the lever (4), can be introduced, furthermore the key bit (7) preferably exhibits a contour (9) with which the locking feature (5) engages in a blocking manner, and additionally the grip part (8) preferably protrudes from the moving element (2) when the key bit (7) is inserted into the holding feature (20) for the manual movement. 4. Ignition lock pursuant to claim 1, 2 or 3, characterized in that the locking feature (5) consists of a slide (10) equipped with a spring (11), preferably of a double slide with two slides (10, 10 ′) that can be moved against each other under the force of the spring (11), wherein a lug (12) on the slide (10) engages with the contour (9) in the key bit (7) of the lever (4), and the contour (9) in the key bit (7) preferably includes a first section (9 a) that runs substantially horizontally with respect to the key bit (7), followed by a subsequent second section (9 b) that ascends in a kind of inclined plane as well as another subsequent third section (9 c) that has a kind of undercut design, in such a way that the slide (10, 10 ′) can be moved under tension of the spring (11) substantially vertically to the insertion direction when the key bit (7) is introduced into the holding feature (20) at the second section (9 b) and subsequently latches into the third section (9 c) due to the force of the tensioned spring (11). 5. Ignition lock pursuant to one of the claims 1 through 4, characterized in that the actuating element (6) is designed in the form of a sliding element (13), in particular with a taper (14) facing the lug (12), the sliding element (13) is preferably movably seated in the grip part (8) as well as on a guiding part (15) on the key bit (7), and furthermore the sliding element (13) can preferably be inserted into the third section (9 c) of the contour (9) so that the sliding element (13), in particular its taper (14) engages with the lug (12) of the slide (10, 10 ′) like a kind of ejector, wherein the lug (12) together with the slide (10, 10 ′) is moved against the force of the spring (11) out of the third section (9 c) of the contour (9) with an unlocked unlatching device. 6. Ignition lock pursuant to one of the claims 1 through 5, characterized in that in the grip part (8) on the sliding element (13) is attached a push button (16) for actuating the sliding element (13) and that the push button (16) together with the sliding element (13) can preferably be actuated manually against the force of a pressure spring (17), which is supported particularly by the key bit (7). 7. Ignition lock pursuant to one of the claims 1 through 6, characterized in that the push button (16) is arranged on the front side (18) of the grip part (8) opposite the key bit (7). 8. Ignition lock pursuant to one of the claims 1 through 7, characterized in that the push button (16) is arranged substantially flush with the front side (18) of the grip part (8) and that a symbol (19), such as the company logo of vehicle manufacturer or the like, for example in the form of an insert, is preferably affixed to the part of the push button (16) that is assigned to the front side (18)."
