20150021309 | STEERING WHEEL HAVING A HEATING ELEMENT, AND FAIL-SAFETY DEVICE USING THE SAME - The present invention relates to a steering wheel having a heating element and a fail-safety device using the same. The steering wheel having a heating element has a rim, a surface of which is coated with an electrically conductive heating element. The heating element includes a plurality of unit heating elements arranged in parallel, each of which includes a first unit line, each of two ends of which connect a positive power-applying terminal and a negative power-applying terminal together in series; a second unit line spaced apart from the first unit line, each of two ends of which connects the positive power-applying terminal and the negative power-applying terminal together in series; and a connection line for connecting the first and second unit lines. | 01-22-2015 |
20140123474 | METHOD FOR FORMING A HEATING ELEMENT FOR USE WITH A STEERING WHEEL - A method of forming a heating element for use with a steering wheel includes (i) forming a first heating part of a heating element which is coated in a longitudinal direction of the rim along an inner diameter portion of the rim by continuously connecting loops having the same shape, (ii) forming a second heating part of the heating element which is coated in the longitudinal direction of the rim along an outer diameter portion of the rim by continuously connecting loops having the same shape, (iii) forming a third heating part of the heating element which is coated in the longitudinal direction of the rim by continuously connecting loops having the same shape between the first heating part and the second heating part; and (iv) adjusting an electrical resistance of the heating element according to a coating width or thickness of the conductive paste. | 05-08-2014 |
20130248507 | METHOD OF APPLYING ELECTRICALLY CONDUCTIVE HEATING ELEMENT ON SURFACE OF RIM OF STEERING WHEEL - A method relates to applying an electrically conductive heating element to a surface of a rim of a steering wheel. The rim of the steering wheel is structured such that a plurality of heating elements formed of a conductive paste is applied to outer circumferential surfaces of a rim. A first connection element for electrically connecting the heating elements is applied along circumferential edges of the rim contacting a separation space. A second connection element formed of a conductive paste and adapted to electrically connect the first connection elements is applied in the separation space. | 09-26-2013 |
20130228561 | STEERING WHEEL INCLUDING HEATING ELEMENT - Provided is a steering wheel having a heating element, wherein a surface of the heating element can be finished by directly transferring thereon a transfer film on which an aesthetic decoration pattern is printed. The heating element is an electrical conductive paste coated on a surface of a rim, and includes a plurality of heating lines that are electrically separated from each other, and a connection unit that electrically short-circuits the heating lines at both ends thereof, and power is supplied to the heating element through the connection unit. | 09-05-2013 |
20120312796 | STEERING WHEEL HAVING HEATING ELEMENT AND APPARATUS FOR ATTACHING THE HEATING ELEMENT TO THE STEERING WHEEL - A steering wheel having a heating element is manufactured by directly transferring a transfer film on which an esthetic decoration pattern is printed. The heating element is an electrically conductive paste on a surface of a rim, and includes heating lines that are electrically separated from each other, and a connection unit that electrically short-circuits ends of the heating lines. Power is supplied to the heating element through the connection unit. | 12-13-2012 |
