  • Patent number: 8898904
    Abstract: A method for coating a steering wheel and a corresponding steering wheel having a steering wheel rim comprising a steering wheel skeleton having a foam layer applied thereto and intended to be encompassed by a cover layer made of leather or plastic are provided. In order to simplify production, the cover layer is positioned on the steering wheel rim as a strip and is fixed to the foam layer on one end. The cover layer strip is then glued onto the foam layer and the lateral edges of the cover layer strip are sewed together in a known manner.

  • Publication number: 20090151506
    Abstract: The invention relates to a method for producing a steering wheel, having the following steps: arranging and fastening at least one steering wheel covering element to the steering wheel skeleton after an outer layer of the steering wheel has been connected to the outside of the at least one steering wheel covering element. The invention also relates to a steering wheel, produced by means of the method, for a motor vehicle, in which it is provided according to the invention that the at least one steering wheel covering element is designed and provided to be arranged on and fastened to the steering wheel skeleton after the outer layer has been connected to the outside of the at least one steering wheel covering element.

  • Publication number: 20050269018
    Abstract: A heatable veneer element for motor vehicle steering wheels and process for producing such a veneer element are disclosed. More particularly, a heatable veneer element for motor vehicle steering wheels is provided that includes a covering veneer piece having at least one layer of wood and/or imitation wood and a heating element which is joined inseparably to the covering veneer piece and serves to heat the covering veneer piece. The covering veneer piece is joined directly and inseparably to the heating element. This has the advantage that the distance which has to be traveled by the heat generated by means of the heating element is minimized and a short heating time (<3 min) of the ring of the steering wheel can thus be realized. The distance to be traveled corresponds essentially to the thickness of the covering veneer piece whose one or more layers can each be made very thin, i.e. <1 mm.
