DE1809979C3 - Coupling device in a motor vehicle door lock - Google Patents

Description

By virtue of the torsion spring (16) in its locking point, installation is much cheaper. The only strong locks ment ("locked") is held. Connection between the ratchet wheel and the safety

lever over the torsion spring avoids without

other components a risk of bouncing when closing the

Door with the external operating device pushed through.

Furthermore, when the door is open and thus when the rotary latch and ratchet wheel are in the open position Locked three arminc safety levers when closing the door and thereby turning the ratchet wheel and pressing it down at the same time the external actuation device by about 2 to 3 mm with a lug on the stop of a canceling lever, which pivots the pawl into engagement
