Door unit for car, has coupling unit transferred from closed state to open state by applying corresponding breakaway force to door wing and retaining open state in accordance with movement of door wing

摘要

The door unit has a gear rod (3) and a drive shaft (4) connected to a door wing (1) i.e. swing door wing. A coupling unit surrounds the drive shaft and represents a clamping function with variable clamping force, where the coupling unit interacts with the drive shaft. The coupling unit is designed in a mechanically switchable manner, where the coupling unit is transferred from a closed state to an open state by applying corresponding breakaway force to the door wing and retains the open state in accordance with movement of the door wing.
