PLANAR HEATING ELEMENT FOR STEERING WHEEL

摘要

A planar heating element for use in the steering wheel of an automobile, a motor boat, or the like, by which feeling of use when a steering wheel is he ld is enhanced by regulating the temperature portion of the planar heating element attached to the steering wheel. The linear heater (17) of a planar heating element (14) is arranged while repeating a loopback along the circumferential direction of a ring portion (12). Since loopbacks of the linear heater (17) are arranged sparsely at the outermost circumferential pa rt of the ring portion (12), temperature can be regulated at those portions of the outermost circumferential part of the ring portion (12) where the palms contact when a user holds the ring portion (12). Feeling of use when the steering wheel is held can thereby be enhanced by regulating the heat generation from the planar heating element (14) in accordance with how it is held by the user.
