Abstract
A central interlocking system for a motor vehicle performs in a normal operation all opening and closing functions. A vehicle provided with the system can be opened and locked without the operation of door closing motors. The outer and inner handles can be selectively blocked individually and jointly by a motor operated control member having two parallel control discs which cooperate with two locking levers. The control member can be released for opening of the door also in a purely mechanical way by turning a door lock keybolt with a key. The locking system has a simple construction and locking motors operating without loads.

An interlocking device for doors and other elements of a motor vehicle, comprising a plurality of locks associated at least with doors, at least one of said locks being a locking cylinder which is actuatable from outside with a key;
- a holding element;
- a blocking element;
- unlocking means;
- an inner door handle and an outer door handle, said lock having a locking element cooperating with said holding element, said locking element in a closed position being blockable by said blocking element and being unblockable under the action of said unlocking means;
- a motor;
- and a control member displaceable by said motor so that a movement of said unlocking means from its position is influenced by said control member, said unlocking means including two independently turnable unlocking levers, one of said unlocking levers being actuatable by said outer door handle and another of said unlocking levers being actuatable by said inner door handle, said control member having control segments with which said unlocking levers individually cooperate.
