Abstract

A central locking system for motor vehicles, not only doors and tailgate and gas tank-cap lids, but also several flaps of containers arranged in the passenger space (gloveboxes, small luggage compartments). These locks can be released and locked jointly by a unitary switch signal, or for specific conditions, both the doors and lids and the flaps can respectively be locked and released separately in groups.
