Abstract
A vehicle door lock having a rotary latch arrangement and a release mechanism. The rotary latch arrangement includes a lock case in which a pivoted rotary latch and a pivoted locking pawl are arranged. The release mechanism includes a first release device with a traverse tube, a cable pull mechanism with a traction element led through the traverse tube and means for actuating the cable pull mechanism, and a pivotable actuation lever that engages in the lock case and which comprises two opposite actuation lever lateral surfaces. The actuation lever is rotatably connected with the first release device to be driven about an actuation lever rotary axis, wherein the locking pawl can be actuated by rotating the actuation lever so that the locking mechanism of the rotary latch can be released.
Claims26
A vehicle door lock for locking and closing doors of motor vehicles, in particular doors of agricultural machines or construction vehicles, for example, tractors, the vehicle door lock comprising:
- a rotary latch arrangement having a lock case including a recess for a locking bolt, a pivoted rotary latch arranged in the lock case and configured to encompass and alternately retain the locking bolt in pre-locked position and a final locked position, a pivoted locking pawl arranged in the lock case and configured to alternately lock the rotary latch in its pre-locked position and its final locked position, and
- a release mechanism configured to unlock the rotary latch, the release mechanism having a first release device with a traverse tube, a cable pull mechanism including a traction element led through the traverse tube, in particular a pull cable or a pull rod, and an actuator coupled to the cable pull mechanism, a pivoted actuation lever engaging in the lock case and having two opposite actuation lever lateral surfaces, the actuation lever being rotatably connected with the first release device in an actuation lever actuating direction to be driven about an actuation lever rotary axis, wherein the locking pawl is actuated by rotating the actuation lever in the actuation lever actuating direction in such a way that the locking mechanism of the rotary latch can be released, wherein
- the actuation lever further includes two drive elements which respectively extend out from one of the two actuation lever lateral surfaces and which respectively have one driving surface,
- the first release device having a U-shaped drive bracket with two pivoted drive levers and a coupling rod, which is connected with the traction element, wherein the drive levers are on one end connected with each other by means of the coupling rod and on the other end slidably abut against one of the two driving surfaces respectively, and
- the actuation lever being rotatably connected with the traction element via the drive bracket to be driven in actuation lever actuating direction.
