Title:
安全機能を有する閉鎖装置
Document Type and Number:
Japanese Patent JP4358449
Kind Code:
B2
Abstract:
In a closing device, in particular for a motor vehicle window or sunroof, having a drive motor (4) for pushing a closing element such as a window pane or roof panel across an opening to be closed, a sensor (3) for detecting a force acting on the closing element in the opposite direction to the direction of closing, and a control circuit (1) for monitoring the force and interrupting the closing element's closing movement if the sensor (3) detects that the force exceeds a limit value, the control circuit (1) varies the limit value depending on force measured at an earlier point in time. As a result, it is possible to distinguish between disruptive influences on the closing device, in particular external acceleration forces acting on the closing element, from forces arising as a result of a body part being trapped in the opening, reversing of the closing device only being permitted in the latter instance.
