Definitions
- Motor vehicle lock in particular motor vehicle door lock
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with a locking element for blocking the locking mechanism when acceleration forces of a predetermined size occur, for example in the event of an accident, the locking element having a pin on the locking mechanism interacts.
- motor vehicle locks and in particular motor vehicle door locks with a locking mechanism consisting essentially of a rotary latch and a pawl are exposed to high acceleration forces in the event of a crash, it is particularly important to prevent the locking mechanism from being opened unintentionally.
- the locking mechanism consisting of a rotary latch and pawl assumes its closed position during normal operation of the associated motor vehicle. To ensure that this closed position is maintained even in the event of a crash, various measures are known in the prior art.
- the procedure is such that an anti-rotation device is provided, which prevents the locking mechanism from opening due to shock or impulse.
- the anti-rotation device can have one or more locking fingers and/or locking stops, which are assigned to a blocking lever or release lever.
- the blocking lever ensures that the pawl is blocked in its locking positions.
- the locking mechanism can be opened using the release lever.
- the anti-twist device is designed overall in such a way that the blocking lever is blocked in the event of a movement caused by a shock or impulse. Blocking the blocking lever can cause The locking mechanism cannot be opened unintentionally because this requires the blocking lever to be lifted out of its position blocking the pawl. This is relatively technologically complex.
- the invention is based on the technical problem of a motor vehicle lock and in particular a motor vehicle door lock as described above To further develop the design so that an effective crash barrier can be implemented in a simple manner, taking into account a functional and long-lasting structure.
- the overall design is such that the lock case 1 is connected to a motor vehicle door, not shown in detail.
- the locking bolt 4 is found on the body side, i.e. it is connected to a motor vehicle body (not shown), for example screwed to it.
- the design is such that the locking bolt 4 in the schematic sectional view according to FIG. 1 B moves in a longitudinal direction X hits an obstacle. Then high acceleration-related inertia forces occur in the said longitudinal direction X, which are shown in FIG. 1B by the relevant arrow
- a locking element 5 is provided according to the invention.
- the locking mechanism 2, 3 is equipped with a pin 6, which interacts with the locking element 5, as will be explained in more detail below.
- the locking element 5 in the context of the invention is a recess 5 in the lock case 1 supporting the locking mechanism 2, 3.
- the pin 6 can therefore dip into the recess 5 in question when the locking mechanism 2, 3 is deflected due to acceleration. This applies at least when the locking mechanism 2, 3 assumes its closed position - as shown.
- the pin 6 is arranged on the rotary latch 2, as shown in the two exemplary embodiments in FIGS. 2A and 2B.
- the pawl 3 can also be equipped with such a pin 6. It is also within the scope of the invention to equip both the pawl 3 and the rotary latch 2 with their own pin 6, which, however, is not shown.
- the pin 6 is not only provided on the rotary latch 2 within the scope of the exemplary embodiment. But in addition, the design is such that the pin 6 is arranged on a load arm 2a of the rotary latch 2.
- the rotary latch 2 has said load arm 2a on the one hand and an additional catch arm 2b on the other hand, which define between them an inlet mouth 7 for the locking bolt 4 caught therein in the closed position according to FIG. 1A.
- the locking bolt 4 lies in the closed position of the locking mechanism 2, 3 on the load arm 2a. It can be seen that when the rotary latch 2 is deformed or moved due to acceleration in the longitudinal direction For this purpose, the pin 6 and the recess 5 are polygonal according to the exemplary embodiment. Based on Fig. 2A and Fig.
- both the pin 6 and the recess 5 are each triangular, which of course only applies as an example and is in no way restrictive.
- the design is such that the pin 6 and the recess 5 are arranged in the longitudinal direction X of a motor vehicle (not shown) when installed, as can be seen directly from the illustration in FIG.
- the rotary latch 2 like the pawl 3, can be made of high-strength steel.
- the rotary latch 2 can be deformed with a corresponding deep-drawing die, which ensures that the pin 6 protrudes relative to a surface of the rotary latch 2 on the load arm 2a.
- This surface of the rotary latch 2 is the one that is deformed or moved in the longitudinal direction X in the direction of the lock case 1 supporting the locking mechanism 2, 3 in the event of a crash. This is ensured by the locking bolt 4, which is also displaced in the relevant longitudinal direction X and is caught by the locking mechanism 2, 3 in the closed position.
