Abstract: A radiant heater apparatus includes an interior panel, a heater main body, and a cover layer. The interior panel includes a deployment portion to be deployed into a cabin space due to a deployment of an airbag apparatus. The deployment portion has a breaking edge where a panel tear portion breaks when the airbag apparatus is deployed. The panel tear portion includes a centerline portion and a pair of sideline portions. The deployment portion includes the breaking edge that is formed along the centerline portion or the sideline portions. The deployment portion has a stress concentration portion that locally applies stress to the cover layer while at least a part of the breaking edge formed along the centerline portion is not in contact with the cover layer, when the deployment portion is deployed and comes into contact with the cover layer.

Abstract: A heater control device controls an electric heater which includes a plurality of heat generating portions. The heater control device determines whether a total energization current value, which is a current value to be supplied to the electric heater when all of the plurality of heat generating portions are energizable, exceeds a predetermined current limit value. The heater control device is configured to, when it is determined that the total energization current value exceeds the current limit value, energize the electric heater while switching, among any or all of the plurality of heat generating portions, those to be turned to a non-energizable off state.

Abstract: A heater is installed indoors and heated to a target temperature. The heater is controlled by a controller. The controller has a regular control module which heats the heater to reach the target temperature. In addition, the controller has a suppressive control module which heats the heater to a suppressed temperature lower than the target temperature by electric power suppressed so that surface moisture adhering on the surface of the heater is decreased. When an activation of the heater is ordered, the heater is heated by the suppressive control module, after that, the heater is heated by the regular control module. The surface moisture is decreased by the suppressed temperature. Therefore, generating rapid boiling and/or rapid evaporation of the surface moisture by the target temperature may be suppressed.

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 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: A radiant heater device for generating a radiant heat, includes a substrate portion having a plate shape and made of an electrically insulating material, a surface member having a sheet shape and disposed on one surface side of the substrate portion, and a heat generation portion formed on the other surface side of the substrate portion. The surface member is formed of a fiber fabric that is provided with a space portion recessed toward the substrate portion in a thickness direction of the surface member and that restricts a heat transfer in a surface direction of the surface member by the space portion.

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.
