Abstract: A radiant heater device radiates a radiation heat when a current is applied to a heat generating part having a flat shape. The radiant heater device has a cover and a supporting member. The cover is arranged in a direction in which the radiation heat is radiated and covers the heat generating part. The supporting member supports the cover. The cover is made of a material having a greater infrared transmissivity relative to the supporting member.

Abstract: A heating system for a vehicle includes: a heater for non-contact heating that emits radiation heat by heat supplied from its heat generating part, which generates heat upon energization, to give warmth to an occupant in a state where a body of the occupant is not in contact with the heater; a heater for contact heating that generates heat upon energization to give warmth to the occupant in a state where the body of the occupant is in contact with the heater; and a control device that controls operations of the heater for contact heating and the heater for non-contact heating. The control device adjusts a heating output provided by the heater for contact heating and a heating output provided by the heater for non-contact heating, and controls the operations to be switchable between: a non-contact heating priority mode to make larger the heating output of the heater for non-contact heating than the heating output of the heater for contact heating; and a contact heating priority mode to make larger the heating output of the heater for contact heating than the heating output of the heater for non-contact heating. As a consequence of the above, the occupant can enjoy a sense of heating that is not stereotypical, and achieve energy saving.

Abstract: A heater device includes a heat generating part that generates heat by energization, and a detection unit. The detection unit detects whether or not a distance between an object around the heat generating part and the heat generating part is equal to or less than a first detection distance with a first detection sensitivity, and whether or not the distance between the object around the heat generating part and the heat generating part is equal to or less than a second detection distance shorter than the first detection distance with a second detection sensitivity that is less sensitive than the first detection sensitivity.

Abstract: A seat heater is configured to heat a passenger seated on a seat disposed in a vehicle. The seat heater includes is a radiant heater that is disposed in an area of the seat that is not in contact with the passenger seated on the seat and configured to radiant heat toward the passenger seated on the seat. The seat includes a seatback configured to support a back of the passenger. The seatback has linear lateral hanging portions extending in a width direction of the vehicle. The radiant heater is disposed above the most upper one of the plurality of liner lateral hanging portions in a vertical direction of the vehicle.

Abstract: A heater device includes a planar heat generating portion configured to generate heat when being energized, a detection circuit having a plurality of planar electrodes disposed on one surface side of the heat generating portion, and a controller configured to control an amount of energization to the heat generating portion based on a detection result of the detection circuit. The heat generating portion and the plurality of electrodes are disposed in parallel with each other. The heater device is configured to have a heat generating region in which the heat generating portion is present and a non-heat generating region in which the heat generating portion is not present when the plurality of electrodes and the heat generating portion are projected in a direction perpendicular to the plurality of electrodes and the heat generating portion. Furthermore, the plurality of electrodes include a heat-diffusion promoting portion provided to be included at least in the non-heat generating region.

Abstract: The heater device is provided with a heater main body, and radiates radiant heat from the heater main body toward an object. The heater main body includes a sheet-like heat generating layer that generates heat and radiates the radiant heat, and a sheet-like heat insulating layer that is disposed on the side opposite to the object of the heat generating layer. The heat insulating layer has a sheet-like first layer having voids and a sheet-like second layer having voids arranged side by side in a thickness direction of the heat insulating layer with respect to the first layer. A porosity of the second layer is higher than that of the first layer.

Abstract: A heater device includes: a distance specifying portion that specifies a distance between a sensing subject, i.e., an occupant and a heater main body as a sensed distance; and a moving mechanism that moves the heater main body. The heater device further includes a heater position control portion that controls the moving mechanism such that the distance between the sensing subject, i.e., the occupant and the heater main body is adjusted to a target distance based on the sensed distance, which is specified by the distance specifying portion.

Abstract: A heating apparatus has a heater body and a heater case. The heater body has a heat generator and emits heat supplied from the heat generator: The heat generator generates the heat when being energized. The heater case houses the heater body and is arranged on a side of an air-bag device for a vehicle adjacent to a vehicle compartment. The heater case is attached to an interior member located in the vehicle compartment or is a part of the interior member. The heater case has an expansion permissive portion that permits the air-bag device to expand into the vehicle compartment. The heat generator includes a portion located at a position corresponding to the expansion permissive portion. The heater body has a low strength portion that has a low strength as compared to the portion of the heat generator and that is located outside the expansion permissive portion.

Abstract: A heater device for heating an user's body seated on a seat includes a heat generating portion that is arranged in a recess recessed from a surface of the seat, and generates heat by energization, a distance detection unit that detects a distance between an object around the heat generating portion and the heat generating portion, and a control unit that controls energization of the heat generating portion. A first control portion controls energization amount of the heat generating portion so that the output of the heat generating portion becomes equal to or higher than a predetermined output, when the distance is longer than an offset distance between the heat generating portion and the surface of the seat. A second control portion controls the energization amount so that the output becomes less than the predetermined output, when the distance is equal to or less than the offset distance.
