DEVICE FOR AUTOMATIC BACK OPENING FIRST THE DOORS OR SLIDING DOORS OF PASSENGER VEHICLES OPERATED BY ROTARY COLUMN

摘要

The device possesses, in addition to a door-actuating means, a force-limiting unit which consists of two relatively displaceable but positively interconnected elements attached to any one of the elements participating in the force transmission and of an element pressing these together. One element of the force-limiting unit is connected to an electrical switch which controls the door-actuating unit with the effect of opening the door.
