Abstract: A heater device has a heater body and a heater case. The heater body has a heat generating part generating heat and radiates the heat supplied from the heat generating part. The heater case is attached to an interior member provided in an interior and houses the heater body, such that an interior-side surface of the heater body is located on a back side of the interior member. The heater case is provided with a ventilation passage through which a space outside the heater case located on the back side of the interior member communicates with the interior-side surface of the heater body.

Abstract: A heater device includes a contact determination unit for determining contact or non-contact of an object based on a change in capacitance between a plurality of electrodes. The contact determination unit is configured to determine (i) the contact of the object in response to a determination that the change in capacitance between the plurality of electrodes per predetermined unit time is a change in one direction and equal to or larger than a first determination threshold value. The contact determination unit is configured to determine (ii) the non-contact of the object in response to a determination that the change in capacitance between the plurality of electrodes per predetermined unit time is a change in a direction opposite to the one direction and equal to or larger than a second determination threshold value.

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 heating part of this radiant heater has a plurality of heating wires. The plurality of heating wires are connected in parallel such that a plurality of parallel groups may be formed by electrodes. Further, the plurality of parallel groups are connected in series by the electrodes. The heating parts are set to reach a radiation temperature for emitting the heat radiation which makes a human to feel warmth. The heating parts have a thermal resistance in a longitudinal direction which is set, when an object contacts on the surface, a temperature of the part where the object touches falls to a suppressed temperature lower than the radiation temperature. The temperature of the heating part increases rapidly in response to electric supply. When there is a contact with an object, the temperature of the heating part decreases rapidly.

Abstract: A heater device for warming a user has a heater panel including a planar heating element which generates heat by energization, a first heat radiation surface formed on one surface side of the heating element, and a second heat radiation surface formed on the other surface side of the heating element. The temperature of the first heat radiation surface is higher than the temperature of the second heat radiation surface. In the heater panel, the first heat radiation surface is configured as a non-contact heater that warms the user in a non-contact manner, and the second heat radiation surface is configured as a contact heater that warms the user in a contact manner.

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 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. Therefore, the occupant can enjoy a sense of heating that is not stereotypical, and achieve energy saving.

Abstract: A control system for a radiant heater device includes a radiant heater device, a heater ECU that controls an energization and a deenergization of a heat generation unit, and an integrated ECU that transmits an operation prohibition command for prohibiting the energization of the heat generation unit and an operation permission command for permitting the energization of the heat generation unit to the heater ECU. The integrated ECU transmits the operation prohibition command when receiving a collision signal indicative of a vehicle collision or a prediction of the vehicle collision, and transmits the operation permission command when not receiving the collision signal. The heater ECU performs the deenergization control when a non-reception state in which the operation permission command is not received from the integrated ECU is continued for a predetermined time or more. As a result, the energization can be interrupted before an occupant is adversely affected.
