    • A seat heater device initiates power supply upon operation of a switch by a seat occupant within a vehicle interior and includes a heater for warming installed in a seat within the vehicle interior and a control unit for controlling energization of the heater for warming. The control unit includes a low-voltage detecting means for detecting whether an input voltage is a regular drive voltage value of the control unit or a voltage value lower than a predetermined voltage value and a switching element that is turned on when the low-voltage detecting means detects the regular drive voltage value of the control unit and turned off when the low-voltage detecting means detects a voltage value lower than the predetermined voltage value. This configuration can avoid heat generation of the switching element even if a leakage occurs in an electronic circuit within the switch due to, for example, insulation failure.
    • 座椅加热器装置在车辆内部的座椅乘员操作开关时启动电源,并且包括安装在车辆内部的座椅中的用于变暖的加热器,以及用于控制用于加热的加热器的通电的控制单元。 控制单元包括:低电压检测装置,用于检测输入电压是否是控制单元的常规驱动电压值或低于预定电压值的电压值;以及开关元件,当低电压检测 当低电压检测装置检测到低于预定电压值的电压值时,装置检测控制单元的常规驱动电压值并关闭。 即使由于例如绝缘故障在开关内的电子电路中发生泄漏,也能够避免开关元件的发热。
