Definitions
- the present invention relates to a device for a motor vehicle lock comprising a receptacle for a locking bolt, wherein the receptacle has an input area and an end area with at least one damping element.
- the damper element is adapted to receive a contact force from the locking pin.
- the invention relates to a motor vehicle door lock with a catch of the catch and pawl, and with a, in a so-called inlet mouth, driving in or cooperating with the catch bolt (also called lock holder, striker, etc.), said inlet mouth or this recording has at least one such damper element.
- Such motor vehicle door locks are basically known.
- the damper element has the task to fix the quietly in the inlet mouth or recording retracting and finally held by the catch in its locked position locking bolt. This results in a relative movement between the locking pin and the receptacle, wherein the locking pin is usually attached to a motor vehicle body while a motor vehicle door (and with it the associated motor vehicle lock) is moved relative to it.
- the receptacle also has the function of guiding the locking bolt in the receiving and outward movement in the receptacle itself or of lifting it into the correct position.
- damper elements have been found to be particularly suitable for reducing noise during the closing of the motor vehicle lock. Nevertheless, there is a need to seek further improvement. In addition, even with such motor vehicle locks a si- chere fixation of the locking bolt against the recording or the catch to be ensured.
- a device is to be specified with which a motor vehicle lock is silent even in the locked state and the dynamic and static loads that occur and can be closed or opened easily.
- the device according to the invention for a motor vehicle lock comprises a receptacle for a locking bolt, wherein the receptacle has an input portion and an end portion with at least one damping element which can receive a contact force from the locking bolt, wherein the damping element has at least one opening in which at least one opposite the damper element is provided dimensionally stable insert.
- the invention makes use of the idea that the damper element itself is formed locally with - compared to other sections of the damper element - dimensionally rigid portions. Such a stiffer partial area can be used in particular for fixing the position or guiding the position of the locking bolt.
- this is regularly made of a thermoplastic material, in particular polyurethane (PUR) or rubber.
- PUR polyurethane
- Shore A hardnesses of 60 to 90 have proven, preferably at about 70.
- the opening in the damper element can also be formed only continuously through the damper element, it is preferred that the opening does not extend through the damper element.
- the opening preferably runs substantially parallel to the adjacent locking bolt. Basically, the cross-sectional shapes of the opening to be adapted to the particular needs, but in most cases, a round or cylindrical opening will be appropriate.
- the number of openings in the damper element can also be adjusted, with between 1 and 3 openings being preferred. Not all openings must be made with a dimensionally stable insert.
- the dimensionally stable insert is preferably held in the opening without additional connecting means.
- positive and / or non-positive connections are preferred, such as a press fit.
- a bulge with a desired extent on the upper side of the damper element can be generated towards the locking pin.
- an application-specific adaptation can be made.
- the opening is designed as a blind hole and the dimensionally stable use in the manner of a plastic pin.
- the through-hole has the same or even a slightly smaller diameter than the dimensionally stable insert to be positioned there.
- This dimensionally stable insert is designed in particular cylindrical and is inserted into the blind hole, that an interference fit with the damper element is formed.
- the plastic pin advantageously ends laterally with the damper element.
- the Shore A hardness of the plastic pin is preferably at least 20% above the Schor A hardness of the damper element, in particular its Schor A hardness exceeds that of the damper element by at least 50% or even 100%.
- the preferred material here is POM (polyoxymethylene) or a comparable material.
- the damper element and the dimensionally stable insert form a safety bearing pad for the locking pin.
- a safety bearing is in particular a composite with the locking pin in the closed locking of locking bolt with the encompassing him rotary latch meant. Exactly in this situation therefore serves the portion of the damper element with the dimensionally stable use as a bearing surface for this fishing camp.
- a kind of fixation of the locking bolt is thus supported in the locked position of the locking bolt, so that in particular relative movements between the rotary latch and the locking pin can be reduced or avoided in this position during vehicle operation.
- a leadership function can be filled with the example, a tolerance compensation is achieved with respect to the positions of locking pin and catch.
- the dimensionally stable insert is provided laterally to a detent position of the locking pin in the receptacle.
- the dimensionally stable insert in the locked position of the locking bolt is aligned laterally to the locking pin, so they lie for example in a common plane which is arranged substantially perpendicular to the inlet movement of the locking pin in the receptacle.
- the motor vehicle lock 2 forms a receptacle 3 for a locking pin 4 indicated here. 1, starting from the left side (input area 5 for the locking pin 4), the receptacle 3 extends into inner areas of the motor vehicle lock 2 as far as an end area 6.
- This end area 6 is now an L-shaped damping element 7 provided, which can receive a contact force starting from the locking pin 4.
- the damper element 7 has at the bottom in the side region of the receptacle 3 between the input region 5 and the end region 6, a plurality of inner, openings 8, wherein in a opening 8, a dimensionally stable insert 9 is arranged.
- the opening 8 is carried out with the dimensionally stable insert 9 in the manner of a bore, which is positioned in the vertical alignment of the locking bolt 4 when resting against the short L-leg of the damper element 7 with closed locking mechanism (not illustrated here).
- the dimensionally stable insert 9 is in this case designed in the manner of a plastic pin.
- the plastic pin in this case has a diameter which corresponds at least to the diameter of the bore, wherein preferably the connection between the bore and the plastic pin is designed in the manner of a press fit.
- the Diameter of the dimensionally stable insert is preferably in the range between 3 mm and 5 mm, in particular in the range of 3.8 mm to 4.2 mm.
- the damper element has a further opening 8 (shown here without a more rigid insert), wherein the position can optionally also be provided in a region of the damper element 7 which lies closer to the end region 6 of the receptacle.
- the stiffer insert 9 is arranged laterally and to a latching position 10, in which the latching bolt 4 is shown here.
- a fishing camp seat is formed, so that a position stability with respect to the position of the locking bolt 4 can be achieved by means of the dimensionally stable insert 7.
- damper element 7 is designed L-shaped, with a longer inlet leg 12 and a shorter impact legs 13 is provided. in the area of the shorter impact limb 13, an elongate opening 8 without a stiffer insert 9 is provided. However, such a stiffer insert 9 is formed in the opening 8 in the longer inlet leg 12 (the two figures show this detail before and after the assembly of both parts).
- the damper element 7 shown is formed rearwardly with a mold contour 14, which allows the fixation of the damper element 7 in the motor vehicle lock - especially in the receptacle 3 -. Also indicated is a bulge 16.
- the stiffer insert 9 (pin) is made of POM here.
- the opening 8 for the dimensionally stable insert 9 in the damper element has a diameter of about 4 mm and a depth of about 12.2 mm (blind hole).
- the dimensionally stable insert 9 has a diameter of 4 to 5 mm. Due to the different diameters, an individual fixing and damping of the locking bolt in the main locking position can be set for different vehicles. In the event that a kind of spring lip (see answersszeicheh 15 in Fig. 4) wiping the inlet leg and the locking pin is provided, this can also be biased to different degrees.
- the length of the cylindrical dimensionally stable insert 9 is for example about 12 mm.
- FIG. 4 shows a locked position of the motor vehicle lock 2, in which the rotary trap 11 securely fixes the locking pin 4 in the receptacle 3. Below the portion of the U-shaped locking bolt 4 encompassed by the rotary latch 11, the damper element 7 can also be seen, which has the dimensionally stable insert 7 arranged in the opening 8.
