<p>In a safety wheel covered with a polyurethane intregal foam layer (5), the contact maker (6, 12, 17) of the electric contacting device for the signalling arrangements is mounted in a resilient manner at a contacting distance to the corresponding contact (2, 10, 16). In order to improve the aesthetic effect of the safety steering wheel and to simplify the components of the electric contacting device, a metal- plastic membrane which is moulded into the polyurethane intregal foam layer is provided as contact maker and mounted at a contact spacing by means of an elastic foam layer (7, 11, 18). <IMAGE></p> |
