Abstract

The invention relates to a vehicle door lock for locking and closing doors of motor vehicles, particularly of doors of agricultural machines, such as tractors, having a rotary catch arrangement and a release mechanism, by means of which the rotary catch arrangement can be unlocked, wherein the rotary catch arrangement has a recess for a lock case having a locking stud, in which at least one, preferably two rotary catches are pivotally supported, wherein the rotary catch is drivably connected to a rotary catch spring, particularly in the rotary catch opening direction (D), and wherein in the lock case at least one pivotable pawl is disposed, by means of which the rotating movement of the rotary catch can be locked, and thus the rotary catch can be closed, wherein the release mechanism has a near controllable releasing unit and a remote controllable releasing unit having a transverse tube with remote control means disposed therein, a remote control button, and a cable pull mechanism operatively connected to remote releasing means, and wherein the pawl can be actuated both using the near controlled releasing unit and the remote controlled releasing unit such that the locking of the rotary catch can be released, wherein the release mechanism has an actuating lever, by means of which the pawl can be actuated, and which can also be actuated by means of the near controlled releasing unit and by means of the remote controlled releasing unit.

Dependent claims

A vehicle door lock for locking and closing doors of motor vehicles, the vehicle door lock having

a rotary latch arrangement having a lock case which has a cutout for a closing bolt and in which is rotatably mounted at least one rotary latch, with the at least one rotary latch being connected to a rotary latch spring for driving the at least one rotary latch in the rotary latch opening rotational direction, the rotary latch arrangement also having at least one pivotable pawl arranged in the lock case for blocking the rotational movement of the at least one rotary latch and thereby locking the rotary latch arrangement, and
a release mechanism for unlocking the rotary latch arrangement, the release mechanism having a locally actuable release device and a remotely actuable release device, the remotely actuable release device having a traverse tube, a remote release device arranged within the traverse tube, a remote-actuation button and a cable pull mechanism operatively connected to the remote release device,
wherein the release mechanism has an actuating lever for actuating the at least one pivotable pawl to release the locking of the at least one rotary latch,
wherein the actuating lever is actuated via the locally actuable release device or via the remotely actuable release device, both the locally actuable release device and the remotely actuable release device being directly operatively connected to the actuating lever to actuate the at least one pivotable pawl to release the locking of the at least one rotary latch.
