  • Safety device for controlling ventilation of a vehicle compartment
    Publication number: 20070155300
    Abstract: A safety device for controlling ventilation of a vehicle compartment. The safety device is mounted in a vehicle with electric windows, including: a power supply connected with a motor for driving the electric window; a controlling circuit connected with the power supply; and a thermal sensor disposed in the compartment of the vehicle and connected with the controlling circuit. The thermal sensor serves to sense the temperature in the compartment and transmit signals to the controlling circuit. In the case that the temperature in the compartment reaches a certain value, the controlling circuit powers on the power supply to activate the motor for opening the window. Therefore, the compartment is ventilated and the temperature of the compartment can be lowered.
