The pin passes through, this process causes the front edge of the first ratchet tooth 18c of the fork member to engage with the pawl 19a de3 pawl member 19, which is thereby rotated clockwise against the biasing force exerted by the spiral spring 22. In this way, the ratchet tooth 18c is first brought into contact with the ratchet member 19 so that the door lock is held in its semi-locked position. Upon further! Continuation of Türvorbewegung in the closing direction, the leading edge 18f actuates the second pawl tooth 18b, the latch or pawl 19 for further rotation _e Finally, bringing the tooth 18b into engagement with the claw, so that the desired fully locked position of the lock is produced as in full lines in I ¹ Ig. 1 and 2 is shown »This closed position corresponds to the position in FIGS.

If the closed and completely locked door is to be opened again, the driver must or Passengers manually operate the inner door handle, which is not shown, to operate it in the usual way Way to turn in the opening direction so that the lever 65, Fig. 3, to its pivot pin 64 against the

When the door is closed, the stop pin occurs 12 with the üiegel- or fork part 18 in drive touch, as presenting in connection with J? Y. 2 has been explained. Thereby the claw in your pointing direction, see Pig. 2 and 3 rotated. In this way, the tension of the spring 66 is increased and the closing plate 54 is caused to rotate clockwise so that the device is released from its locked position. This allows the door to be opened when the outside door handle is brought into the door opening position.

It is often desirable to lock the door from the outside without using the door key. i.e. by keyless operation.

To this! Function with the door lock device according to the invention To realize it is only necessary to close the door by means of the outer door handle while it is held in the door open position after the inner door close push button has been depressed. Through this process it is achieved that the door is closed, while the orifice plate 56 in its dash-dotted line Line in Fig. 7 is held. As a result, the claw 19 is rotated clockwise, with her

Projection 19b moved to its upper position will; the .Feder 66 seeks to extend and rotate the sole plate 54 clockwise. However, in practice, the left one becomes inclined outer part 56b of the shoulder 56a of the orifice plate in engagement with 'the projection 19b of the claw 19 held and thereby maintaining the locking position anyway, since in this case the upward fc displacement of the projection 19b, which is caused by "the clockwise rotation of the claw 19, to a Sliding movement of the part 19b along the inclined ■ Part 56b leads. Therefore, the latter part cannot be released from the projection 19b and accordingly, clockwise rotation of the closing plate 54 can be prevented. Even if the If the outer door handle is operated in the door opening direction, the door is closed and locked Position held. Any unauthorized door opening from the outside of the vehicle is made effectively prevented.

Figs. 8-12 show a second embodiment of Figs Invention. In the drawing figures, the same or similar components are represented by using the same Reference numerals as identified in the first embodiment with the addition of an apostrophe.

In this embodiment, the pivot pin 55 'of the closing plate -54' is received by an elongated opening 70, which is cut into the plate 54 ', see the figure. 8 and 10. Ain lateral projection 71 'is formed so that it on the claw 19 with a lateral projection 72' at the orifice plate 56 may engage _o

The G-lid cover 21 'with a W-shaped opening 73 is within the range of motion of the pivot pin oil ', which is used for the mutual pivotable fastening of the closing plate 54 'and the opening plate 56' during the pivoting movement of the plate 54 'about the pivot pin 55' trained in the. Lid is incised, as shown in fig, IO by the one hand undulating, closed dotted line "When the closing plate 54 'from the unlocked to the locked

"The operation of the second Aus-P management style explained.

In case the door is to be opened which has been closed and kept in its normal state the driver or a passenger must operate the usual inside door handle to open it to move. This causes the inner opening lever 65 'to move against the pin 64' turn clockwise, see Fig. 8, and raise the left end of the orifice plate 56, Fig. 10, so that a protrusion 71 on the latter is brought into pressure contact with a protrusion 72 on the pawl 19 ' will. In this way the iCLaue 19 'is caused to in ührzeigerrichtung to the pin 17 ', Fig. 10, to rotate, whereby the closed position of the Door lock device canceled and the door is brought into an openable position.

On the other hand, if it is desired to open the door from the outside of the vehicle, the usual one must outer door handle-be operated to move it in the door opening direction to rotate so that the outer opening rod to rotate the orifice plate 56 'in the Clockwise, Fig. 10, is moved downwards. This will unlock the facility and allows the door to be opened.

If the door is to be locked which has been brought into its closed position, the inner one must be Push button in the vehicle are depressed, whereby the inner locking bar is moved downwards. Instead, the outer locking rod can also go up can be pulled by operating the door key in the usual way from the outside. The striker 54 'is thereby caused to rotate counterclockwise and into position brought to FIG. In this way, the pivot center of the opening plate 56 'is at 57' shifted a small distance in Fig. 10 to the left. Under these conditions, even if either the inner or the outer door handle is operated in the opening direction, so that the opening plate 56 'is rotated clockwise, the projection 71 on the plate does not thereby engage

with the associated projection. 72 are brought. the Orifice plate 56 'thereby' does not perform its function out and the door is not opened, but in held in their locked position.

Palis mistakenly the interior, not shown The locking pushbutton has been depressed and the door has thereby been brought into its locked state, causes the rotation of the fork 18 'by engagement with the entering socket pin, as in previous pail the claw 19 'clockwise, RLg. 9, rotates so that the projection 72 is raised in position together with the pawl will. The spring force of the spring 66 'accumulated thereby causes the closing plate 54' to move upwards shifted and the plate is rotated clockwise. The establishment will be from their before locked position released so that the door can be opened by operating the outer handle can.

If desired, the door can be opened from the outside of the vehicle without using the door key To close and lock, it is only necessary to close the door while the outside door handle is held in its door open position after

909831/0207 " ²¹ "

the inner door lock push button has been pressed. By this process, the claw 19 'is rotated clockwise as in the previous jail and the projection 72 on the claw 19' is raised together with it in its dtposition. The spring 66 is thereby extended and acts on the plate 54 'in order to rotate it in a clockwise direction. However, since the left hook-like end 56c ^{1 of} the orifice plate 56 'is held in engagement with the protrusion 15a ^{1 of} the base plate 15', the upward displacement of the protrusion 72 caused by the clockwise rotation of the pawl 19 'becomes disengaged executed with the projection 71. As a result, the movement of the claw 19 'is only carried out without any effect, the energy being consumed by increasing the length of the spring 66'. The engagement of the hook-like end 56c 'of the opening ^{plate and the projection 15a 1 of} the base plate is thus effectively maintained and not disturbed, preventing any clockwise rotation of the closing plate 54' and maintaining the closed state of the door lock device. Actuating the outer door handle in the opening direction does not initiate a door opening process after the door is closed.

909831/0207

When the closing plate 54 'is out of the locking division, i'ig. 10 is moved into the unlocked position, the head 74 of the pin 57 'is thereby from the left of the central projection 75 of the W-shaped Opening 73 moved to the right of the protrusion. This counteracts the action of the closing plate 54 ' the Seder 63 'shifted upwards, whereby their pivot pins 55 'along the side wall "of the elongated bearing opening 70 slides. After this displacement movement, this projection acts as a stop for the closing plate 54 'with respect to its counterclockwise rotational movement. This effectively prevents the plate from moving into its locking position, as far as it is concerned is not intentionally turned in the same direction of rotation as explained above

A reverse transition from the unlocked to the locked position can be achieved by rotating the Closing plate 54 'are executed in a clockwise direction against the action of the spring 63', the Pin head 74 with the pin 57 'from the right in the Mg. 10 is shifted back to the left. After a such a locking, the projection 75 in turn acts as a stop against unintentional unlocking
