Abstract

Abstract A cut-off switch is provided between the motor driving a sliding panel and the power supply for the motor. The cut-off switch becomes operative when the torque supplied by the motor during the displacement of the panel between the open and closed positions of the panel exceeds a predetermined value. An inhibiting device inhibits the actuation of the cut-off switch when the panel is in the immediate vicinity of its closed position.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 173 words
A device for avoiding accidents when closing a movable panel, comprising an electric motor for driving said panel between an open position and a closed position, means for connecting the motor to a power supply, means for cutting off the power supply connecting means when the torque furnished by the motor during the displacement of said panel between said positions exceeds a predetermined value, and means for inhibiting said cut-off means when said panel is located in the immediate vicinity of its closed position, wherein said cut-off means comprise a first electromagnetic relay having a coil, a second electromagnetic relay having a coil connected in a first switch capable of being controlled by the coil of the second relay, a second switch capable of being controlled by the first relay, the coil of the first relay being connected in series with the motor and with the first switch, the coil of the second relay being connected between the power connecting means and earth in series with the second switch and the inhibiting means.
