Definitions
- At least the rotary latch in a motor vehicle lock is in engagement with a locking bolt or lock holder.
- the rotary latch and lock holder interact in such a way that the rotary latch can be pivoted around the lock holder and the locking mechanism engages by means of the pawl.
- the rotary latch is consequently exposed to environmental influences and can come into contact with water, for example due to rain.
- the solutions known from the prior art have proven themselves to this day. With increasing electrification of the motor vehicle lock, however, there is a need to completely separate the dry area from the area that is exposed to environmental influences. This is where the invention comes in.
- the object of the invention is to decouple the environmental influences as far as possible from the electronic or electrical components of the motor vehicle lock. According to the invention, an improved and structurally simple and therefore cost-effective motor vehicle lock is to be provided, with which environmental influences in the field of electronics or electrics are kept away.
- the actuating lever extends through the plastic housing of the motor vehicle lock and serves as a transmission link in the actuating chain for unlocking the locking mechanism. If a seal is now inserted on the actuating lever and in particular in the area of the passage opening, reliable sealing can be ensured, as a result of which a maximum of operational reliability can be provided for the electric drive.
- the seal can be inserted into the release lever at least in certain areas. If the release lever is also designed in such a way that the seal extends into the release lever at least in some areas, a compact design can be combined with the great advantages of tightness. On the one hand, it is possible to ensure reliable transmission of the force between the release lever and the actuating lever and, on the other hand, to combine a compact design with design advantages. On the one hand, a high level of tightness can be achieved between the dry area and the wet area and, on the other hand, reliable power transmission can be achieved with a minimum of structural space. In addition, by integrating the seal into the release lever, protection for the seal can be formed.
- FIG. 1 shows a three-dimensional view of the actuating chain for unlocking the locking mechanism, with a section through the actuating lever and a pivot axis of the pawl being reproduced;
- a release lever 11 acts on the pawl 5.
- the release lever 11 is provided with a return spring 12 and has a recess 13 into which a seal 14 is inserted.
- the seal 14 itself is attached to the operating lever 3 and seals the wet area 15 against the dry area 16 in the motor vehicle lock 1 .
- the operating lever 3 extends from the wet area 16 into the dry area 15 , the operating lever extending through the housing of the motor vehicle lock 1 .
- the housing 17 has a passage opening 18 for this purpose.
- the passage opening 18 can at the same time form a bearing point for the actuating lever 3 .
- a lever arm 19 is formed on the actuating lever 3 itself and can in turn be brought into engagement with a worm wheel 20 .
- FIG. 2 shows a sectional view of the motor vehicle lock 1 with a view of the actuating chain 21 . Shown is a section through the housing 17, the pawl 5, the axle 6, the reinforcement plate 7, the release lever 11, the seal 8, the operating lever 3 and the worm gear 22.
- the solution according to the invention provides a secure means of providing a structurally favorable option for driving the release lever 11 or for unlocking the locking mechanism 2 on the one hand, and on the other hand the seal 14 can be used to ensure reliable sealing in the Motor vehicle lock are guaranteed.
- the electric drive or the electric components in the motor vehicle lock 1 can thus be securely accommodated in the motor vehicle lock 1 against environmental influences.
