Device for locking the steering spindle of a vehicle

A device for locking the steering spindle (2) of a steering gear of a vehicle, having a blocking pin (6) which is arranged in a housing (3) and can be displaced from a release position into a locking position and vice versa, having the following features:

• a) on a side facing the steering spindle (2) the device (1) comprises a guide part (12;
• 12′) having a guide recess (13) which is fitted in a form-fitting manner to the blocking pin (6) and in which a front part (22) of the blocking pin (6) is displaceably mounted;
• b) in the guide part (12;
• 12′) a first recess (15;
• 15′) is provided with a first opening (23) which opens into the guide recess (13);
• c) in the blocking pin (6) is a recess (21) which, in the locking position of the blocking pin (6), lies opposite the first opening (23) of the first recess (15;
• 15′) of the guide part (12;
• 12′);
• d) a spring-actuated securing element (17;
• 17′) is arranged in the first recess (15;
• 15′) of the guide part (12;
• 12′);
• e) the first opening (23) of the first recess (15;
• 15′) of the guide part (12;
• 12′) is closed by a closure element (20) which is fastened on the inside of the housing (3), can be displaced in a second recess (19) perpendicularly with respect to the first recess (15;
• 15′) and on which an end of the spring-actuated securing element (17;
• 17′) which faces said closure element is supported, with the result that when the housing region on which the closure element (20) is fastened is removed in the locking position of the blocking pin (6), the securing element (17;
• 17′) is pushed by means of the spring force exerted on the securing element (17;
• 17′) into the recess (21) of the blocking pin (6) and secures the blocking pin (6) in said locking position.
