Abstract

A steering column lock for motor vehicles with a warning device operative whenever the door of the vehicle is opened upon the key having been failed to be pulled out.

Claims

1. Steering column lock for motor vehicles of the type wherein a locking of the steering column takes place only after withdrawal of the key from the locking cylinder (2) thereof by movement of a lock bolt (4) made of electrically conductive material into a locking position and with a closed electrical contact arrangement for acoustical or optical warning installations when the lock bolt is not moved into its locking position, characterized in that the electrical contact arrangement comprises said lock bolt (4) and a contact pin (11) projecting into the path of movement of said bolt (4), said contact pin being housed for movement by said lock bolt into and out of an insulated element (10), said element being disposed in opposite relation to said lock bolt as compared to said locking cylinder, whereby said lock bolt (4) and said contact pin (11) will contact each other during movement of said bolt thereby making an electric contact whenever said lock bolt (4) is not moved into its final locking position.

2. A lock for motor vehicles according to claim 1, in which a spring is provided in said element (10) for said contact pin with one end of said spring being in contact with said pin and the other end thereof with a lead-in cable.
