Abstract

Official abstract text for this publication.

A motor vehicle lock, in particular a motor vehicle side door lock, comprising a locking mechanism with a rotary latch and at least one pawl, wherein the rotary latch can be blocked in at least one catch position by means of the pawl, an electrical drive unit for unblocking the locking mechanism, a lock housing with a wet chamber and a dry chamber, wherein the locking mechanism is arranged in the wet chamber and the drive unit is arranged in the dry chamber, and wherein at least one mechanical connection is arranged on the lock housing and protrudes into the dry chamber such that a mechanism arranged in the dry chamber can be actuated.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A motor vehicle lock comprising: a locking mechanism including a rotary latch and at least one pawl, wherein the rotary latch is blocked in at least one catch position by the at least one pawl, an electrical drive unit that is operable for unblocking the locking mechanism, a lock housing with a wet chamber and a dry chamber, wherein the locking mechanism is arranged in the wet chamber and the electrical drive unit is arranged in the dry chamber, at least one mechanical connection that is arranged on the lock housing and protrudes into the dry chamber, an actuatable mechanism arranged in the dry chamber that is actuated via the mechanical connection, at least one further mechanical connection that is arranged on the lock housing and protrudes into the wet chamber, and another actuatable mechanism arranged in the wet chamber that is actuated via the further mechanical connection. 2 . The motor vehicle lock according to claim 1 , wherein the locking mechanism is unblocked by operation of the mechanical connection. 3 . The motor vehicle lock according to claim 1 , wherein the actuatable mechanism comprises an anti-theft device that is arranged in the dry chamber, and the anti-theft device is actuated by operation of the mechanical connection. 4 . The motor vehicle lock according to claim 3 , wherein the anti-theft device is actuated electrically. 5 . The motor vehicle lock according to claim 1 , wherein the mechanical connection includes a Bowden cable. 6 . The motor vehicle lock according to claim 5 , wherein the mechanical connection includes a Bowden cables heath that receives the Bowden cable and the Bowden cable sheath is sealingly arranged on the lock housing. 7 . The motor vehicle lock according to claim 5 , wherein the lock housing includes a bearing point for receiving the Bowden cable. 8 . The motor vehicle accordingly to claim 7 , wherein the bearing point comprises a sealed connection between the wet chamber and the dry chamber. 9 . The motor vehicle lock according to claim 5 , wherein two or more Bowden cables are connected to the lock housing. 10 . The motor vehicle lock according to claim 9 , wherein at least one of the two or more Bowden cables extends into the dry chamber and least one of the two or more Bowden cables extends into the wet chamber. 11 . The motor vehicle lock according to claim 1 , wherein the further mechanical connection is a Bowden cable. 12 . A motor vehicle lock comprising: a locking mechanism including a rotary latch and at least one pawl, wherein the rotary latch is blocked in at least one catch position by the at least one pawl, an electrical drive unit that is operable for unblocking the locking mechanism, a lock housing with a wet chamber and a dry chamber, wherein the locking mechanism is arranged in the wet chamber and the electrical drive unit is arranged in the dry chamber, at least one mechanical connection that is arranged on the lock housing and protrudes into the dry chamber, and an actuatable mechanism arranged in the dry chamber that is actuated via the mechanical connection, wherein the mechanical connection includes a Bowden cable, wherein two or more Bowden cables are connected to the lock housing, and wherein at least one of the two or more Bowden cables extends into the dry chamber and least one of the two or more Bowden cables extends into the wet chamber.
