ABSTRACT:
A safety window for a car which is capable of being automatically moved to its window closing position when the car speed exceeds a predetermined speed. The safety window comprises a control device for controlling the operation of the power window, which comprises a sensor for detecting a car speed, a comparator for comparing the car speed with a predetermined window closing car speed, and a power supply circuit for supplying the reference voltage to the comparator in an automatic window operation mode. The power supply circuit includes a select switch provided with a manual operation contact and an automatic operation contact, a reference voltage generator connected to the automatic operation contact and adapted to generate the reference voltage in the automatic window operation mode, and a limit switch adapted to send selectively the reference voltage from the reference voltage generator to the comparator. In accordance with the present invention, the car window can be closed when the car speed exceeds the predetermined window closing car speed, thereby reducing the burden of manipulation on the driver and enabling him to concentration his attention on what he is driving.
