<p>1. Steering wheel for motor vehicles having a jacket which is cut out of a planar structure, in particular leather, and an integrated inset heating element which can be connected to the electric power source, in which the inset heating element is formed from a chain structure. The chain structure has a shape congruent with the shape of the jacket and is sewn to the blank of the jacket. The chain structure is held in a hem-like manner at the borders of a textile structure or of the blank of the jacket itself. Said structure can be provided on its underside with protuding areas, for example knobs, hooks, claws or the like, with which it can be hooked to the carrier material located below it. The inset heating element is connected to the power source by means of terminals extending along its entire width, a temperature limiter being provided in conjunction with a thermostat controller or PCT in the circuit for the purpose of control. The device is produced in such a way that the inset heating element formed from knitted or crocheted planar structure is prefabricated as a blank or preform so as to closely fit the jacket and is connected to the jacket by bonding or in another suitable manner and subsequently the inset heating element is applied to the steering wheel together with the jacket in a manner known per se. <IMAGE></p> |
