Kraftfahrzeugtürschloß mit elektrischer Schließhilfe und Öffnungshilfe

摘要

The subject matter of the invention is a motor vehicle door lock or the like with a lock latch (2) and a detent pawl which keeps the lock latch in the main catch and the preliminary catch, with an electrical auxiliary closing drive (5) which is turned on after the lock latch (2) has reached a preclosing position and then transfers the lock latch (2) by motor into the main closing position, and with an electric auxiliary opening drive (10) which is turned on to raise the detent pawl (3) off the main catch or the preliminary catch of the lock latch (2). This door lock is characterized in that the coupling of the auxiliary closing drive (5) has a mechanical coupling element (9a) which can be raised for decoupling and which can be raised by a correspondingly controlled actuation of the electrical auxiliary opening drive (10). One version is especially important in which power supply to the electrical auxiliary opening drive (10) takes place via the extra battery (17) which is always recharged from the vehicle electrical system (15) (active electrical redundancy), but power supply of the electrical auxiliary closing drive (5) takes place directly from the vehicle electrical system (15).
