Steering wheel for a vehicle

摘要

The steering wheel has an engagement system (23A-C), a spring (38) that is applied to the engagement system, and an unfastening ring (30). The unfastening ring can move between two positions. When it is in an unfastened position the ring moves the engagement system sufficiently against the spring so as to free a space at least equal to the maximum radial space occupied by the engagement boss (7) of the steering column to which the steering wheel is affixed. In the fastened position the ring is not in contact with the engagement system.
