The door lock 1 according to the invention has the following operation: In the opening phase of the door lock 1 is no Locking pin 6 in the rotary latch 10. The locking piece 66 is with its counter-toothing 62 from the limb locking gears 61 of the rotary latch members 7,8 out. The common Spring 77 of the rotary latch members 7,8 holds the catch 10 open by the tensile force, so that at the same time a receptiveness for the locking pin 6 on the door frame of the vehicle consists. Likewise, the pushes the pawl lever 27th associated compression spring (not shown) the locking pin 25 away from the long side lock wall 30 and the locking piece 66 is in a different mounting position on the outer Peripheral surface 71 in the region of the limb locking teeth 61st at.

In the opening phase, the locking piece 66 thus does not engage in the limb locking toothing 61 of the rotary latch members 7, 8, but lies on the outer peripheral surfaces 71 (representative for both peripheral surfaces on the rotary latch members 7,9) at. The opening state of the rotary latch 10 means at the same time that the door of the vehicle is open.

When closing the door of the locking bolt 6 passes in the direction S (arrow) the lock box opening 14 and is through the Door swing against the locking piece 66 near areas of the Grooves 32 and 73 pressed so that the common Spring 77 is stretched, the rotary latch members 7.8 um the rotational holding bolts 40,41 pivoting into another position, i.e. enter the Umgriff and thus the locking pin 6 fall like fall.

By the rotation of the rotary latch members 7,8 are the Link locking toothings 61 of the long side lock wall 30 and thus the locking piece 66 facing such that its counter teeth 62 in the link latchings 61 contacting can intervene. Thus, the catch 10 is fixed closed.

When operating the remotely actuable release device 12th the following happens:

By pressing the button 69 is transmitted by the transmitting Pulling cable or rod 16 in cable direction 82 (arrow) of in the Hebelarmfreisschnitt 46 located engaging projection 45th to the horizontal lever arm 64 of the pawl lever 27th pushed away from the short side lock wall 44 in FIG Direction of the rotary latch member 8 is pivoted. Thereby is formed on the rotary latch facing away from the vertical lever arm 63 Locking piece 66 from the two limb locking gears 61 swung unlatched, so that by the spring force of common spring 77 of the rotary latch members 7.8 the catch 10 is released and the locking pin 6 in the direction Ö (arrow), passing through the box opening 14, the lock box 5, which leads to the door opening. To the position of the crossbar to adjust the lock box, the Screwing the crosshead tube 24 at the pipe bracket angle part 17 solved so far that the truss tube 24 to the screw is pivotable. In addition, the screw connection of the remotely operated release mechanism on the crossbar, so that it is längsverschieblihc on the truss tube. The Truss tube can now in the appropriate position to a Door be brought, with the remote-controlled release device 12 by the pull rope or a corresponding rod when pivoting, depending on whether the pull rope or the rod pulled out of the truss tube by pivoting or pushed in, along the truss tube is moved. Has the truss pipe a desired Pivoting position with respect to the lock or with respect to the Door reached, the truss pipe can with its the lock box opposite fastening device such as a Pipe crimping attached to the door or a door frame then, whereupon the remotely operated triggering device by tightening the adjusting screw on the truss tube is determined and optionally the crossbar on Pipe bracket is also set again.

Upon actuation of the actuatable release device 13 happens following:

By pulling the door handle 18 is the upright, slightly inclined Head 74 of the door handle-actuated Nahauslösehebels. 2 moved toward the truss tube 24, wherein the Nahauslösehebel 2 is pivoted about the axis 67. It pushes the molded cam 49 against the end-side spring-supported Locking pin 25 of the rotary latch facing away from the vertical lever arm 63. By movement of the locking pin 25 in the direction of Langseitenschloßwandung 30 is the counter teeth 62 of the Locking piece 66 swung out of the limb locking teeth 61 unlatched so that the force of the common spring 77 can act. The rotary latch 10 is opened, the Rotary latch members 7,8 occupy a new rotational position and the locking pin 6 from the grooves 32,73 in the direction Ö (arrow) released. The door of the vehicle is now open.

Closed is the catch 10 by entering the Locking bolt 6 in the box opening 14 and by the jerky Load of the grooves 32,73 Drehfalllenglieder 7.8.

In the door lock according to the invention with pivotable truss tube is advantageous in that the number of transmission levers, arranged on the truss pipe triggering device is reduced, whereby by the fact that the release mechanism or button on the truss tube with a cable or a Rod is hinged to the pawl lever and also the trigger mechanism longitudinally displaceable on the truss tube and is fixed, the truss tube in any desired Position can be pivoted. Because the attack point of the pull rope or the rod to the pipe bracket angle part removed from the pivot point of the traverse is, is at the pivoting of the traverse tube, the pull rope or the pull rod more or less from the truss pipe pulled out or pushed into this, with this Changes with the longitudinally movable remote-controlled Triggering device 12 can be compensated.
