Title:
HEATING APPARATUS AND HEATING DEVICE FOR SEAT OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2007/102502
Kind Code:
A1
Abstract:
A heating apparatus excellent in quick heating at the time of starting and subsequently
enhancing comfortableness by satisfying temperature stability. A heating
device for the seat of vehicle is also provided. The heating apparatus comprises
a heater having a heating element, a first temperature detection element for
detecting the temperature of the heater, a second temperature detection element
for detecting the temperature of the heater, and a circuit for controlling the
temperature of the heater by output signals from the first and second temperature
detection elements. The first and second temperature detection elements are
arranged to receive different amounts of heat, and the signal for controlling
the temperature of the heater is arranged to become the logical OR of a signal obtained
by comparing the temperature signal voltage of the first temperature detection
element with a first reference voltage and a signal obtained by comparing the
temperature signal voltage of the second temperature detection element with
a second reference voltage.
