Definitions
- Motor vehicle lock in particular motor vehicle door lock
- motor vehicle lock is to be understood broadly in this case and applies not only to motor vehicle door locks, but also, for example, to motor vehicle locks in connection with the locking of seats, flaps, etc.
- motor vehicle locks are nowadays and increasingly operated by electric motors. This means that special comfort applications can be implemented and the operating forces are low.
- Motor vehicle lock and in particular motor vehicle door lock like this to further develop so that the design effort is reduced and a functional solution is provided, which in particular enables a perfect closing process after the locking mechanism has been opened.
- both levers are coupled to one another, there is a rotationally fixed connection, so that an action on the actuation release lever is and can also be transmitted to the pawl release lever, which in turn then lifts the pawl from its engagement with the rotary latch.
- the rotary latch can open with spring support and release an associated and previously caught locking bolt.
- the door equipped with the relevant motor vehicle lock can be opened easily.
- both levers are separated from each other, so that if necessary, the pawl can be returned to its starting position using a pawl spring, for example, and can fall into the rotary latch.
- the pawl release lever moves with the pawl and performs a relative movement relative to the actuation release lever.
- the coupling member is mounted on the actuation release lever so that it can pivot about its axis.
- the design is such that the coupling member interacts with a stop on the pawl release lever. If the coupling member is therefore in its “engaged” state, the coupling member, which is mounted on the actuation release lever so as to be pivotable about its axis, ensures that over the
- an electric motor drive is also provided.
- the electric motor drive is generally used to open the locking mechanism electrically or by electric motor.
- the electric motor drive generally acts on the actuation release lever. If the coupling member is in its “coupled” state at this stage, the action on the actuation release lever immediately results in the pawl release lever, which is mounted on the same axis, being taken along via the actuation release lever. The pivoting movement of the pawl release lever is then transferred to the locking mechanism and specifically causes the pawl to be lifted from its locking engagement with the rotary latch. The associated motor vehicle door can be opened.
- a motor vehicle lock and in particular a motor vehicle door lock is made available, which, with a structurally simple structure, allows functionally reliable operation and in particular a functionally reliable closing process of the locking mechanism even in the event of a possible blockage of the electric motor drive in the example case.
- the blockage is released by actuating the operating lever and in particular the external operating lever, for example by pulling on an external door handle.
- the coupling member that couples the two levers together in normal operation is pivoted and ensures that both levers can perform a relative movement against each other.
- a pawl spring assigned to the pawl is able to move the two levers against each other, so that the pawl can return to its basic position using the pawl spring in order to then be able to lock the rotary latch with the locking bolt caught by the rotary latch. All of this can be done technologically and constructively particularly easy to realize and implement.
- the essential ones are the essential ones
- FIG. 1 shows the motor vehicle lock according to the invention in a perspective overview
- the figures show a motor vehicle lock, which is not limited to a motor vehicle door lock.
- this has a locking mechanism 1, 2, which is only fully indicated in FIG. 1, and consists of a rotary latch 1 and associated pawl 2.
- the locking mechanism 1, 2 is shown in the closed state in FIG. Only the pawl 2 can be seen in the other FIGS. 2 to 3.
- the Pawl 2 can be pivoted in the counterclockwise direction indicated in FIG.
- the rotary latch 1 which is only partially indicated there, comes free from the pawl 2, can swing open with spring support in the counterclockwise direction, which is also indicated here, and releases a locking bolt, which is not expressly shown.
- the associated motor vehicle door can be opened.
- both levers 3, 4 are coaxial around the common axis 5 are stored.
- the actuating lever 7 is also mounted on the same axis as this axis 5 and is designed as an external actuating lever 7 according to the exemplary embodiment.
- the operating lever or external operating lever 7 may be mechanically connected to an external door handle, not expressly shown.
