Anti-jamming system for motorized displacement parts with traction arrangements detects occurrence of a jam when strain force acting on traction element exceeds a threshold

摘要

The system has a device (20) for detecting a jam situation that can trigger reversal or stoppage of the displacement motion. The occurrence of a jam is detected from the strain force (F) acting on the traction element (5), i.e. when the strain exceeds a defined threshold value. The jam detector can be directly or indirectly coupled to the traction element An Independent claim is also included for a displacement arrangement for adjustable parts in motor vehicles.
