Abstract: A seat heater includes first heat-generating elements embedded in a seat so as to correspond to first sites of a seat occupant, second heat-generating elements embedded in the seat so as to correspond to second sites of the seat occupant, and a controller for executing a fluctuation control in which a first set temperature of the first heat-generating elements and a second set temperature of the second heat-generating elements are increased or decreased in each of a plurality of predetermined time periods. The controller sets the first set temperature to be higher than the second set temperature in one of the time periods and sets the second set temperature to be higher than the first set temperature in another of the time periods.

Abstract: A vehicle seat heater, which is to be fitted to a vehicle seat, includes a base sheet and a heater wire laid in the base sheet. The heater wire is laid in the base sheet so as not to orthogonally intersect its predicted wrinkle lines R. As a result, disconnections of the heater wire caused by repeated deformations of the vehicle seat heater can be suppressed.

Abstract: A planar heating device and a seat equipped with the device include: first and second warming heaters connected in parallel with electric power source; thermistor; thermostat connected in series with second warming heater; a heating part, i.e., first warming heater, that heats thermistor and thermostat; and controller to control temperatures of first and second warming heaters in accordance with temperature information from thermistor. For a period until thermostat turns off, quick-heating property is improved by energizing first and second warming heaters.

Abstract: A seat with a heating device is provided which realizes a configuration in which the arm, palms and finger tips of a user can easily be warmed when the user uses the seat with the heating device. When the user is seated in a seat with a heating device and feels cold due to it being winter, the user controls a switch to heat the seat, whereby energization of heating elements 3a, 3b, 3c is started which are connected to a power supply via electric wires. When the energization of the heating elements 3a, 3b, 3c is started, heat generated thereby is conducted to skin materials 2a, 2b, 2c and surfaces of the skin materials are warmed. When the user places his or her arm on an armrest portion 5, the arm is warmed via the skin material 2c, whereby the user can feel the sensation of comfortableness.

Abstract: A vehicle seat heater 10, which is to be fitted to a vehicle seat 50 and which includes a base seat 12 and a heater wire 14 laid in the base seat 12, has a reinforcing seat 18 attached in a side portion 10b placed in a seat side portion 50c of the vehicle seat 50. Edges of the reinforcing seat 18 have portions 18a extending in back-and-forth directions of the side portion 10b and opposing each other at least on a front side of the side portion 10b, where a laying area for the heater wire 14 is provided between the opposing portions 18a. Thus, disconnections of the heater wire 14 can be suppressed in the side portions 10b of the vehicle seat heater 10 placed in the seat side portions 50c of the vehicle seat 50.

Abstract: A vehicle seating system is provided in which infrared rays radiated from a surface of a thermal radiation member at the time of heating are emitted to a bodily portion of an occupant which extends from his or her head to shoulders for implementation of effective heading. In a case of a planar heating element 2 being installed above a side windowpane, the planar heating element 2 is installed so as to confront an upper body of an occupant who is seated in a seat which extends from his or her head to shoulders, and when the planar heating element 2 is energized, an upper body of the front-seat occupant can be warmed by radiation heat. In a case of a planar heating element 3 being installed in a center pillar portion, when the planar heating element 3 is energized, the upper body of the front-seat occupant can be warmed by radiation heat.
