<p>A steering wheel assembly comprises a central body 10 attached to a steering column. A steering wheel rim 12 is supported by the central body 10. An air bag device 20 is mounted on the central body 10 for limited movement in a first direction towards and away from the body. A horn operating switch having a contact stud 52 fixed relative to the central body 10 and a contact arm 54 movable by the air bag device relative to the contact stud 52 into engagement therewith and coil springs 38a, 38b and 38c which resiliently urge the air bag device 20 away from the central body in the first direction. The coil springs act on the air bag device in a second direction which is transverse to the first direction. The coii springs have a greater stiffness in the second direction than first direction. <IMAGE></p> |
