Abstract

The present invention is to provide a power regulated window having a window glass to be closed intentionally when some foreign body is pinched by the window glass for security reasons. When a close signal is output to a semiconductor switching element from window regulator switches, the window glass is closed. When some foreign body such as arm or fingers is pinched by the window glass, a load current of a motor becomes abnormal and the motor rotates reversely to open the window glass in order not to damage the foreign body. Besides this protective function, when the foreign body is pinched by the window glass and a prohibit signal to invalidate the reverse rotation is output, a reversing controller is stopped and the window glass is closed continuously by a bypass switching element.

Claims

1. A power regulated window comprising:

a semiconductor switching element to control an electric power supply to a motor to regulate a window glass responding to open and close signals;

a current detector to detect a load current of the motor when the window glass is closing;

an abnormal judge means to monitor whether or not the detected load current is abnormal;

a reversing controller to output the open signal to the semiconductor switching element to reverse the rotation of the motor when the detected load current is abnormal, and

further comprising a reverse rotation prohibiting controller which prohibits the reverse rotation of the motor when it receives a prohibit signal for not allowing the reverse rotation of the motor by stopping the output of the open signal of the reversing controller.

2. The power regulated window as claimed in claim 1, further comprising a bypass controller to output a bypass signal when it receives the prohibit signal, and a bypass switching element which supplies the electric power to the motor to rotate in the direction of closing the window.

3. The power regulated window as claimed in claim 1, wherein said bypass controller outputs the bypass signal when the prohibit signal is received and the detected load current is abnormal, and the bypass switching element supplies the electric power to the motor to close the window glass responding to the bypass signal.

4. A power regulated window comprising:

a semiconductor switching element to control an electric power supply to a motor to regulate a window glass responding to open and close signals;

a current detector to detect a load current of the motor when the window glass is closing;

an abnormal judge means to monitor whether or not the detected load current is abnormal;

a reversing controller to output the open signal to the semiconductor switching element to reverse the rotation of the motor when the load current is abnormal, and

further comprising a bypass controller to output a bypass signal when it receives a prohibit signal, and a bypass switching element which supplies the electric power to the motor to rotate in the direction of closing the window responding to the bypass signal.
