Electrically heated steering wheel

摘要

In a steering wheel mounted heater, there is provided a heat conductive sheet directly in contact with the outer surface of the rim portion. This conductive sheet is then intimately covered first with an electrically insulating sheet and secondly with an electrically heat generating member. This configuration is provided in order to quickly achieve uniform temperature distribution on a given zone of the steering wheel which zone is most likely gripped by the driver during the vehicle driving.
