Central door-lock system for motor vehicles
First Claim
1. A central door-lock system comprising:
- a plurality of door latches each includinga detent displaceable between a closed position securing the respective door to the respective doorpost and an open position permitting the respective door to separate from the respective doorpost,a manual door-opening handle,mechanism including a primary latch member connected to said handle and connectable to said detent and movable between a lock position preventing said handle from displacing said detent between said open and closed positions and an unlock position permitting said handle to displace said detent between said open and closed positions,means including a secondary latch member connected to said primary latch member and displaceable between a lock position urging said primary latch member into the respective lock position, an unlock position permitting said primary latch member to move freely between the respective lock and unlock positions, and an antitheft position positively holding said primary latch member in the respective lock position;
respective servoactuators for said latches each including an actuator element connected to the respective secondary latch member and means including a servomotor for displacing the respective secondary latch member via the respective actuator element between the respective lock, unlock, and antitheft positions; and
means including a central switch connected to said servomotors for operating same jointly and thereby jointly displacing said secondary latch members between the respective positions.

Abstract
A central door-lock system has a plurality of door latches each of which is provided with a detent displaceable between open and closed positions for allowing the door to open and for holding it closed. This detent can be acted on by a manual door-opening handle through mechanism including a primary latch member which is connected to the handle and connectable to the detent and which is movable between a lock position preventing the handle from displacing the detent between the open and closed positions and an unlock position permitting the handle to displace the detent between the open and closed positions. A secondary latch member is displaceable between a lock position urging the primary latch member into the respective lock position, an unlock position permitting the primary latch member to move freely between the respective lock and unlock positions, and an antitheft position positively holding the primary member in the respective lock position. Each latch is operated by a servoactuator having a servomotor connected to an actuator element for displacing the respective secondary latch member between the respective lock, unlock an antitheft positions. A central switch is connected to all of the servomotors to operate them jointly and thereby jointly displace the secondary latch members between the respective positions.
