Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides an external opening lever pivotally supported on a base module and an electric module including a casing having a lock mechanism therein, and when the lock is mounted and adjusted, and is set to a non-operating position. To secure it, the invention relates to a door lock for a motor vehicle comprising a spring adapted to cooperate with this lever. In these locks, the external opening lever comprises an element to which the end of the cable providing the link to the external manual handle is attached.

[0002] The external opening lever is set to a non-operating position by a spring called "one-off", but its unique function is to control the external opening lever with a cable to ensure the entire course. To be able to move. Therefore, it is a calibrated spring whose purpose is to exert a force on the external opening lever when needed and to lock it in the inoperative position, when adjusting the link between the external opening lever and the external handle It is valid.

[0003] For this purpose, the spring has a branch, one end of which is located in a jaw or slot provided in the external opening lever. When the spring fork is positioned in the jaw, it applies an elastic force to the lever,
Hold it in the inactive position. Once the lock is installed and each element is adjusted, actuation of the external lever pulls the cable until the spring disengages from the jaws of the external opening lever. This spring is then held inactive throughout the useful life of the lock, which is why it is referred to as a "one-off" spring.

[0004] However, from time to time, painting operations must be performed. This is when the external opening handle has to be removed, meaning that the original adjustment of the element linking the external opening lever and the external opening handle is lost, but this linking element is Consists of a cable and its end piece fixed to the end of the lever. The painting operation can be performed but the above adjustments have to be made again, which means a reset of the "one-off" spring on the external opening lever. The only access to the remaining lock is through a passing orifice for inserting the external opening handle into the outer door panel.

[0005] Therefore, the operator must remove everything or hook the spring with a special tool in order to reposition it in the jaw, the latter method being
Some dexterity is required and time is wasted.

It is an object of the present invention to overcome this problem in a simple manner without having to remove the lock, which requires special tools which are prone to difficulties in repositioning the spring to the position where the lever is reset. It is realized without.

According to the invention, the motor vehicle door lock has a member for resetting the external opening lever, which is mechanically linked to the spring and tilted by pressing with a tool through the notch in the door. The pressing operation can move the spring from a position where the external opening lever is not set to a position where the external opening lever is set by the spring and fixed to the inoperative position.

[0008] By providing this member for actuating the spring used to set the external opening lever, the lever opens the passage opening in the body structure which is made accessible by removing the external opening handle. It can be reset simply by pressing with the tool through. Several types of tools can be used, such as screwdrivers and punches.

[0009] In one embodiment, the resetting member is a lever supported on the casing between the guide means, the first end of which has a hole therein, and the hole is formed by a spring. Is passed through, such that the end is positioned in the jaw of the external opening lever by tilting the resetting lever.

[0010] Other features and advantages of the present invention will become apparent from the following description, taken in conjunction with the accompanying non-limiting drawings, illustrating one embodiment. The drawing shows a lock 1 for a motor vehicle door, which is not shown except for the outer panel, but which is provided with an opening 3 for an external manual opening handle, not shown.

The lock 1 comprises a base module and an electric module, the casing 4 of which comprises a known, self-explanatory type of locking mechanism. The lock also has an outer opening lever 5 pivoted on the base module for rotation about axis XX and returned to the inactive position by a spring, not shown.
The end 5a of the lever 5 has an end member 6, to which one end of a cable 7 linked to an external opening handle is fixed.

The lock also comprises a spring 8 having a central part housed in a compartment 9 erected on the casing 4 and two branches 11, 12 protruding outside the compartment 9. The branch 11 is itself a lever bearing 20
And is supported and fixed by a metal piece 10 fixed to the base module. The end of the second branch 12 is arranged on the outer opening lever 5 and
Can be located in a jaw 13 forming a hook nose, which is particularly indicated in FIG.

The lock is mechanically linked to a spring 8 and is formed with an outer opening formed to be tilted when pressed with various tools 14 such as a screwdriver or a punch through the cutout 3 of the door 2. It has a member for resetting the lever 5.
In the embodiment shown, the resetting element is a lever 15, for example, a guide consisting of two parallel plates 16 connected to the casing 4 extending on both sides of the lever 15 as shown. It is arranged to be supported by the casing 4 in a region intermediate between the means.

The first end portion of the lever (15) has a hole 18, thereby providing a passage for the bent end 19 of the branch 12 of the spring 8. The end portion 19 is positioned inside the jaw 13 by tilting the lever 15 from the non-set position (FIG. 1) so that the end portion 19 is fixed to the non-operation position where the lever 5 is set.

The reset lever has a second end portion 21 formed by an arm, beyond the guide plate 16 with respect to the end 17, in which the tool 14 (only the shaft is shown)
Notch 22 is provided for receiving the end 14a. Also, the lever 5
As such, it has a side tab 23 extending laterally with respect to the reset lever 15 extending in a plane substantially parallel to the plane of the external opening lever 5.

FIG. 3 shows two possible positions of the reset lever 15, namely:
One is the set inactive position 15A of the reset lever 15, where the end 19 of the spring 8 is located in the jaw 13, the lever 15 is lowered in the direction of the casing 4, and The other is an unset up position 15B, in which the lever 15 is inclined about an axis which is essentially at the same height as the guide plate 16. In the second position, the spring 8
End 19 of jaw 13 is moved away from jaw 13 and is positioned below it, so that external opening lever 5 is held in the inoperative position only by a return spring (not shown), since spring 8 is no longer Because it does not act on it.

The external opening lever 5 must be locked in the set, rear, inactive position shown in FIG. Once the end 19 of the spring 8 is located in the jaw 13, it forms an integral part of the lever 5, which is fully fixed. The branch 19 is arranged at an angle to this branch 19, which is cut out from the outside through a cut-out portion, as described above, of a tool 1 of any type.
4 is controlled by pressing the notch 22 of the lever 15.
The end 14a of the tool presses inside the notch 22. Pressing with the tool 14 causes the lever to be tilted between the guide plates 16 and its end 17 to be raised from a lowered position on the casing 14 so that the lever unset position 15B
(FIG. 3).

The end of the branch 19 that was under the jaw 13 raises the latter so that it slides over the outer surface and raises the lever 5, and the end 19 moves into the jaw 13. Until it induces a tilt around axis XX. The elastic stress of the branch 19 moves the outer opening lever back to the initial position, where it is firmly fixed by the spring 8 (FIG. 3, position 15A).

Therefore, in this position 15 A, the lever 15 resets the external opening lever 5, and enables a known adjustment and mounting operation of the external opening handle for proceeding. To release the lever 5 from the spring 8, one simply pulls the cable 7, whereby the lever 5 is tilted and the end 19 of the spring 8 is released from the jaw 13.

The tab 23 projecting from the side of the lever 5 forms a stop which limits any rebound of the mechanism when tilted, ensuring a stable position, in particular corresponding to the delivery position in FIG. Are shown.

As mentioned above, the reset lever 15 is very simple to open the external opening lever 5 by simply pressing with some tool through the opening 3 in the body structure of the door 2 after removing the external opening handle. The operation makes it possible to perform the reset. This eliminates the time wasted prior to removing locks or performing complex manual operations on the spring 8 using special tools.

The invention is not limited to the embodiments described here, but can be incorporated in different modes of operation. For example, the reset lever 15 can be guided by means other than the plate 16.
