1. An apparatus for adjusting the position of a tiltable steering column in an automotive vehicle, said steering column having a steering shaft rotatably mounted in said steering column, said apparatus comprising:
- a bracket fixedly secured to the vehicle body structure, said bracket including a first set of teeth;
a clamping plate connected to said steering column, said clamping plate including a second set of teeth disposed on one face thereof and operative to meshingly engage said first set of teeth in a series of different relative positions to secure said steering column at different positions relative to the vehicle body structure under the application of an external force against said locking member, said clamping plate further including at least one resilient wing formed integrally with said clamping plate, said at least one resilient wing operative to produce a biasing force to move said clamping plate out of engagement with said bracket.

6. A fastening device for a tiltable steering wheel assembly including a steering shaft rotatably supported in a steering column of an automotive vehicle, comprising:
-
a bracket fixedly secured to the vehicle body structure, said bracket including a first set of teeth; a locking member connected to said steering column, said locking member comprising a clamping plate including a second set of teeth disposed on one face thereof and at least one resilient wing formed integrally therewith, said at least one resilient wing operative to produce a biasing force to move said locking member out of engagement with said bracket whereby said second set of teeth meshingly engage said first set of teeth in a series of different relative positions to secure said steering column at different positions relative to the vehicle body structure under the application of an external force against said at least one resilient wing, said force being applied by a pivoted cam, said cam being mounted on a lever arm.
