The invention "relates to a motor vehicle door lock, whose case cooperates with a locking bolt, with the case a detent lever is coupled, with which a Pawl cooperates, which in turn by ge one of the! outside of the vehicle through the outside handle, and "vom Driving convincing ago by the inside handle actuatable release lever is movable, and one of a safety lever movable locking lever is provided for locking the lock in its closed position.

The purpose of the invention is to create a device that, when the door is locked, allows the door to be opened from the outside and / or to prevent the inside of the door by means of the door handles,

For this purpose, the invention provides that a second locking lever is provided, which via a linkage from the lock cylinder can be actuated here and prevents actuation of the latch from both the outside handle and the inside handle.

Further features of the invention emerge from the following description and the claims.

The invention is illustrated below with reference to the drawings, for example explained in more detail, namely shows:

1 shows a side view from the inside and FIG. 2 shows an end view from the inside of an inventive device Door lock in locked and unlocked position of the parts,

Figure 3 βχπ, β side view corresponding to Figure Λ and

Figure 4 · an end view corresponding to Figure 2 of a door lock according to the invention in the locked and secured position of the parts _}

Figure 5

and 6 partial views corresponding to FIG. 3 to explain the internal fuse.

The subject matter of the invention is an external security system that is additional to the internal security system of a motor vehicle door lock. Which he- ± * ± Note applies to all similarly built motor vehicle

door locks applicable. In the drawings, therefore, is an exemplary embodiment a lock according to the invention shown and explained only in the locked state, in which the case engages in the locking bolt. The design of the trap and the locking bolt is not important here.

A motor vehicle door lock according to the invention is on an angled Lock plate 1 constructed together with the latch, a locking lever 3 is pivotably mounted on a pivot 2. The pivot pin has a suitable profile to prevent relative movement between the latch and the locking lever.

A pawl 4, which is mounted on the lock plate 1 so as to be pivotable about a pin 5, works together with the locking lever 3.

A closing spring 6 is held tensioned between an approach to aem üasthebei ο un & an approach to the pawl 4. It holds both parts in engagement with each other and loads the latch in the opening direction.

The nature of the cooperation and the general formation of these parts is known and is not explained here

The following precautions are taken to lift the pawl 4 and thus to open the door.

* I 1 · · «· ■ t

The pawl 4 is provided with an eye 7 on which a Release lever 8 engages. This release lever is connected to the outer door handle. One actuation in the opposite direction of the arrow the action of the spring 6 causes the bast lever 3 to be released and thus the trap in the opening sense

On the lock plate 1 a further release lever 9 ¹ ^ m an axis 10 is pivotally mounted and loaded by means of a spring 11 in the locking direction. On the release lever 9, a transmission lever 12 is articulated, which is connected to an inside door handle. An actuation in the direction of the arrow in Figure 2 causes the pawl to pivot and thus the release of the latch in the opening direction. The release lever 9 engages for this purpose by means of a Uase 13 on a Uase 14 of the pawl 4.

Such motor vehicle door locks generally have a safety lever attached to the inside of the door, which activates the outer and the ± mize door handle prevented «,

For this purpose there is a safety lever 15 on a pin 16 pivotally mounted on the lock plate 1, which is connected to a safety button (not shown) via a linkage 17.

A sip spring 18 holds the safety lever 15 in each of its

27251

"both end positions.

The safety lever 15 is provided with a fork 19 into which an approach 20 of a seal 21 engages .. The latch lever is aiii a pin 22 pivotally mounted on the lock plate ■ and designed as an angle lever.

The safety device 15 has an approach 23, and. the release lever 9 is provided with a lase 24 ·

In the unlocked state of the lock (FIG. 2), the nose 24 can pivot past the attachment. In the secured state (fig 4) the shoulder 23 engages the nose 24 and prevents a pivoting movement of the release lever 9 »so that the door lock from Inside handle cannot be opened.

The locking lever 21 has an attachment 25 which cooperates in the same way with an attachment 26a on the pawl 4 In the unlocked state (ügur 1) the pawl can be pivoted. Prevented in the secured state (Figure 3) the approach 25 a pivoting movement of the pawl so that the The door cannot be opened from the outside.

If you omit the approach 25, the door can be opened by operating the outer door handle when the lock is secured.

of the invention is; on the journal 22 of the fog 21 a second bending lever 3 ^ pivotally mounted.

An eye 32 of the second Eiegelebel 3 ^ is used for reading to a part 33> the one with the key 3 ^ of the door lock connected is. This part 33 can, for example, be an eccentric which, when locking from the Schlleßzyllnder is taken and the second SiegelheOel 31 ia Pfellrlcntung of Figure 1 pivoted.

The locking lever 31 is also designed as a Winlceliiebel and has an approach 35 which is close to the approach 25 of the first locking lever 21 is »

A toggle spring 36 holds the second locking lever 3 ″ i of its two end positions _β

The locking lever 31 has an elongated recess 37, durcl which engages a driver 38 which is attached to the first locking lever.

In the illustrated embodiment, the recess and the driver serve to attach the shoulder 25 to the locking lever 21 to be superfluous and the approach 35 of the second locking lever for both door locks (from the inside and from the lock cylinder) to use",

27251

In the completely unlocked position to Sugar i neither the '* approach 25 is still the tab 35 is effective. The shoulder 25 works together with the shoulder 26a on the pawl A "and the shoulder 35 with a shoulder 26.

The driver 38 engages on the inside of the recess

37 at.

If the locking lever 21 is pivoted into the locking position, the driver 38 takes the second sealing lever in the arrow— direction into the position shown in Figure 6 with »In this the lugs 25 and 26a as well as 35 and 26 are in the locking sense opposite to.

If the locking lever is swiveled back, the driver engages

38 on the outside of the recess 37 and takes the second Lock lever 31 back in the position of the parts according to Figure 1 with « The toggle spring 36 brings the locking lever 31 back into his End position.

If the position of the parts according to Figure 1 only the second bending lever 31 in the direction of the arrow in the locking position according to FIG 3, the driver 38 is removed from the recess 37 not influenced »In Figure 3 it is assumed that the safety lever 15 has been actuated. Both approaches (25 and 35) have a blocking effect.

If the door! Ττη ensicherung lifted in this position of the parts, then the position dsr parts results after. Figure 5>. Here the extension 25 releases the extension 26a, but the extension 35 locks due to its position relative to the extension 26. The driver 38 could slide as far as the stop on the outside of the recess 37.

The invention is not limited to the illustrated and described exemplary embodiments, rather details be adapted to the respective application.
