Description

Technical area

The present development relates to a motor vehicle door lock with an emergency unlocking device and a motor vehicle door equipped with such a motor vehicle door lock.

background

Common locks for motor vehicle doors have a lock unit with a lock latch, which can be brought into engagement with a body-side arranged lock bracket. Furthermore, common motor vehicle door locks are equipped with a locking and / or unlocking mechanism, which is remote-controlled, electrically or mechanically actuated. In case of malfunction of such locking and / or unlocking mechanism, the door lock can not be unlocked. An unlocked door lock can be opened by means of an inside door handle or outside door handle. When unlocked door lock, for example, a mechanically connected to a lock mechanism of the door lock door inner handle or door outside handle be coupled to the latch such that an actuation of the relevant door handle leads to an opening movement of the latch in an open position. Then the unlocked door lock can be opened.

Common emergency release systems for motor vehicle doors typically provide mechanical access to the locking and / or unlocking mechanism of the door lock, so that a malfunction of the locking and / or unlocking mechanism can be quasi-mechanically bridged. An emergency unlocked door can typically be opened in a conventional manner as a result of the operation of an inside door handle or outside door handle.

In contrast, the present invention is based on the object to provide an improved with respect to its Notentriegelungsfunktion motor vehicle door lock, which allows opening the door without operating a door handle.

Advantageous embodiments

This object is achieved with a motor vehicle door lock according to the independent claim 1 and with a motor vehicle door according to claim 13 and with a motor vehicle according to claim 14, wherein advantageous embodiments are the subject of dependent claims.

In that regard, a motor vehicle door lock is proposed which has an attachable to a motor vehicle door lock unit. The lock unit comprises or has a lock latch, which is movable between a closed position and an open position and can be brought into engagement with a lock bracket arranged on a motor vehicle body. The motor vehicle door lock also has an emergency unlocking device, which is manually operable and mechanically coupled to the latch. The emergency unlocking device may be mechanically or directly coupled directly or indirectly with the latch.

This makes it possible to bring about an opening movement of the latch alone by actuating or activating the emergency unlocking, so that the vehicle door lock can be opened without operating a door handle and the door can be transferred to an open position. Such a motor vehicle door lock is particularly suitable for flush-mounted in a door outer panel outside door handles. In the event of a malfunction of the handle, the lock or a locking and / or unlocking mechanism, the door lock can also be opened without actuating the handle by means of the emergency unlocking device proposed here.

If, for example, the transfer of the door outside handle recessed flush into the motor vehicle door into an open position requires electrical energy which may not be available in an emergency, the door can also be opened without actuating the outside door handle by means of the emergency unlocking device provided here.

According to a further embodiment, the emergency unlocking device has a lock cylinder which is rotatably arranged on the motor vehicle door. The lock cylinder can in particular be accessible from the outside by means of a suitable key, or be actuated, in particular rotatable. The lock cylinder can in particular be directly mechanically coupled to the lock catch. The end user is provided in an emergency so far immediate accessibility to the latch of the vehicle door available. The lock cylinder rotates only in an open position, when a suitable matched to the mechanical code of the lock cylinder key is rotated in the lock cylinder. As a result, an abusive opening of the motor vehicle door lock and the motor vehicle door can be prevented.

According to a further embodiment, the lock cylinder is flush in an outside door handle or in a door outer panel of the Motor vehicle door arranged. The flush arrangement of the lock cylinder allows a shapely and aerodynamic favorable embodiment of the emergency release. The flush arrangement can virtually conceal the lock cylinder or the emergency unlocking device, in particular if the lock cylinder has a color adapted to the environment.

According to a further embodiment, the lock unit has a lock mechanism, by means of which the lock latch can be transferred from the closed position into the open position. The lock mechanism, for example, cause a rotational movement of the lock latch from the closed position to the open position. The lock mechanism may, for example, have a pawl, which engages with the rotatably mounted lock latch. The pawl may, for example, have a donor section which is in mechanical operative connection directly with the lock latch. The pawl may further comprise a slave section, which is directly or indirectly in operative connection with the emergency unlocking device or with the lock cylinder. A movement of the lock cylinder initiated by the end user through the emergency unlocking device can be transmitted to the lock mechanism and ultimately to the lock latch for opening the same.

According to a further embodiment, the emergency unlocking device is connected via a first mechanical coupling with the lock mechanism. By way of the first mechanical coupling, a mechanical actuation, in particular a mechanical movement of the emergency unlocking device, for example a rotary movement of the lock cylinder, can be transmitted into a movement of a component of the lock mechanism. For example, by means of the first mechanical coupling, a pawl in operative connection with the latch can, for example a pawl, can be moved.

According to a further embodiment, the first mechanical coupling to a linkage or a control cable. Tensile forces and / or pressure forces between the emergency unlocking device and the lock mechanism or the lock latch can be transmitted by means of a linkage or an actuating cable. The first mechanical coupling also allows a spaced-apart arrangement of emergency unlocking or locking cylinder and lock latch or lock mechanism. This enables a variable arrangement of the emergency release device on the motor vehicle door. In such embodiments of the motor vehicle door, in which, for example, an outside door handle is arranged at a distance from the lock mechanism or at a distance from the lock catch, the distance between the emergency unlocking device and the lock catch can be bridged via the first mechanical coupling.

According to a further embodiment, the lock mechanism of the motor vehicle door lock on a rotatably mounted pawl, which is in engagement with the lock latch. The pawl has a slave section which is mechanically coupled to an encoder of the emergency release device. The pawl can itself be rotatably mounted on the lock mechanism with respect to an axis. The slave portion may be disposed radially spaced from the axis on the pawl. A tensile or compressive movement, which can be transmitted to the pawl via the first mechanical coupling, can be converted into a rotary movement of the pawl to that extent. The pawl itself may further comprise a radially spaced from the axis encoder portion which is in direct operative connection with the latch, for example with an outer edge of the latch.

According to a further embodiment, the lock unit on a support which is designed for mounting on the motor vehicle door. On the carrier, the castle hall is also arranged. Furthermore, the lock unit has an outside door handle, which is also arranged on the carrier.

The fact that the outside door handle and the latch are arranged on a common carrier, a previous separate arrangement of outside door handle and motor vehicle lock on the vehicle door can be omitted in an advantageous manner. The lock unit can be provided in the form of a single preconfigured or prefabricated module by a motor vehicle supplier. With arrangement and attachment of the lock unit on or in the motor vehicle door both the outside door handle on the vehicle door and the lock bracket can be attached to the vehicle door in a single assembly step.

In addition, a comparatively complicated mechanical connection between the outside door handle and the lock bracket or a lock mechanism accounts. In the course of the final assembly of the motor vehicle or the motor vehicle door, it is only necessary to mount the lock unit provided here on the motor vehicle door. In or on the lock unit, the outside door handle and the lock bracket are arranged to function. A mechanical coupling between the outside door handle and the lock bracket must henceforth no longer take place within the framework of the motor vehicle final assembly or the production of the motor vehicle door. As a result, manufacturing costs and the production cost can be reduced. In addition, components for the separate mechanical connection between the outside door handle and the lock bracket or a lock mechanism can be omitted.

The carrier can act as a mounting bracket for both the outside door handle as well as for the lock bracket or for a lock mechanism having the lock mechanism. The carrier may be designed in particular for mounting on an inner side of a door outer panel. But it can also be designed for mounting on the inner door panel or other support structure components of the vehicle door. The outside door handle can be pre-assembled on the carrier before the carrier is attached to the motor vehicle door. It is also conceivable that the outside door handle is removably mounted on the carrier, so mounted for mounting the lock unit on the vehicle door, the carrier without outside door handle first from the inside of the door outer panel and then the outside door handle from the outside through a handle opening of the door outer panel connected to the carrier becomes.

According to a further embodiment of the motor vehicle door lock, a drive is arranged on the carrier, which is coupled to the outside door handle and which is adapted to move the outside door handle from a rest position to an open position. In the rest position, the outside door handle is integrated into an outer door panel of the vehicle body or it is arranged flush with the door outer panel with a corresponding arrangement on the vehicle door. In the Ausstellposition the outside door handle stands out with a manually engageable bracket section of the door outer panel.

In the deployed position, the outside door handle is graspable for an end user so that it can exert an opening movement on the outside door handle. In the rest position, the outside door handle is flush-mounted in the door outer panel. He is in this position unmanageable and therefore can not be operated manually. A flush-mounted in the outer door panel outside door handle proves to be particularly advantageous from an aerodynamic point of view as well as from an aesthetic point of view.

The drive may in particular comprise an electric motor, which is typically engaged with the extension of the outside door handle. The drive may further comprise a gear, for example a worm or spindle drive, by means of which the extension and thus also the entire exterior door handle can be moved from the rest position into the deployed position.

According to a further embodiment of the outside door handle is in reaching the Ausstellposition with the recipient of the lock mechanism in engagement. Between the rest position and the Ausstellposition the outside door handle can be out of engagement with the taker. Typically, arranged on the extension of the door outside handle donor portion of the outside door handle engages the taker as soon as the outside door handle reaches its deployed position. In the deployed position, however, the outside door handle still exerts no force on the taker.

The taker remains in a starting position as long as the outside door handle is still in the raised position. Upon reaching the deployed position, a second mechanical coupling between the outside door handle and the lock mechanism is typically made. Another movement, typically applied to the outside door handle by the end user, then results in actuation of the occupant, thereby transferring the latch to its open position.

According to a further embodiment, the outside door handle, starting from the rest position over the Ausstellposition away in an actuating position movable or transferable. Upon reaching the operating position, the latch is transferred via a second mechanical coupling with the lock mechanism in the open position. At the latest when reaching the open position of the outside door handle, the second mechanical coupling between the outside door handle and the lock mechanism is made. Due to the second mechanical coupling, a movement of the outside door handle directed beyond the deployed position, in particular a pull movement directed towards the outside in the vehicle transverse direction, leads to movement of the receiver, which is transmitted to the sender of the lock mechanism, as a result of this Movement releases the latch or transferred to its open position.

The provision of three different positions for the outside door handle, namely a rest position, a deployed position and an operating position allow the realization of a flush mounted in the outside door panel outside door handle. This can be transferred by means of the drive in the Ausstellposition in which he is manually taken by an end user to open the door. To open the door, the outside door handle is to be transferred from the open position to the operating position. The drive provides a kind of mechanical connection or a second mechanical coupling between the outside door handle and the lock mechanism ready as soon as the outside door handle reaches its deployed position.

According to a further embodiment, the outside door handle is coupled with a return member arranged on the carrier. The outside door handle is while against the action of the return member from the rest position in the direction of deployment position, also movable in the direction and up to the operating position. The return member, which may have, for example, a spring or a spring mechanism, causes an automatic movement of the outside door handle from the operating position to the deployed position, possibly also from the Ausstellposition back to the rest position.

According to a further aspect, the development further relates to a motor vehicle door with an outer door panel and with a door inner panel and with an extending between door outer panel and inner door panel end face. The front side is located in a designed as a hinged door motor vehicle door on a side facing away from the door hinge end of the vehicle door. The motor vehicle door also has a previously described lock unit, which is arranged between the door inner panel and the door outer panel.

The lock unit, thus her carrier, can be arranged and attached to one of door inner panel and door outer panel. Preferably, the lock unit is attached to the inside of the door outer panel and fixed. With the arrangement of the lock unit on the motor vehicle door, both the door lock, that is, the lock mechanism and the lock latch, and the outside door handle can be arranged and fixed to the vehicle door with only a single assembly step.

According to a further embodiment, the outside door handle is arranged in its rest position flush with the door outer panel. A flush design of the outside door handle on or in the outer door panel makes it possible to design the outer door panel handle recess-free or significantly reduce the depth of a recessed grip in the area of the outside door handle. This makes it possible to position the outside door handle much closer to a front end of the door outer panel, as is the case with motor vehicle doors with outside door handles protruding from the outside.

A displacement of the outside door handle in the direction of the front side of the motor vehicle door is advantageous for the integrated design of the lock unit, which comprises at least one common support, the outside door handle and the lock latch. The dimensions of the lock unit, in particular the carrier or mounting bracket, can be significantly reduced in this way. Also, this can reduce the space required and the material consumption for the lock unit.

According to a further embodiment of the motor vehicle door, the latch of the lock unit is arranged on the front side of the motor vehicle door or it protrudes from the front side. The outside door handle is embedded in the door outer panel or integrated flush with it here. The previously described displacement of the outside door handle in the direction of the front side allows an integrated arrangement and design of latch and outside door handle on one and the same carrier, which proves to be advantageous in terms of manufacturing and assembly technology.

According to a further embodiment, a distance between the outside door handle and a front end of the door outer panel is less than 10 cm, less than 8 cm, less than 5 cm, less than 3 cm or even less than 2 cm. The shorter the distance can be selected, the smaller the lock unit can be formed and the space otherwise required for this space in the motor vehicle door can be used elsewhere.

Finally, according to a further aspect, a motor vehicle is provided which has at least one previously described lock unit or at least one motor vehicle door described above.

At the B-pillar 3 is one in the door opening 5 protruding lock handle 16 , This one is with a lock latch 26 the motor vehicle door 10 releasably engageable. The lock latch 26 is accordingly at the front 12 the motor vehicle door 10 arranged.

This in 2 schematically illustrated motor vehicle door lock 15 has a lock unit 20 with a lock mechanism 24 on. The lock mechanics 24 includes a latch 26 and one with the latch 26 engaged pawl 44 , The lock latch 26 is between a in 2 shown closed position S and one in 3 shown opening position O movable at the lock unit 20 stored. It is in particular rotatable on the lock unit 20 stored. It has a groove 36 on, in which the lock hanger 16 insertable and in which the lock bracket 16 depending on the position or orientation of the latch 26 lockable.

The handle 44 can be designed as an emergency release pawl. It is, for example, with respect to an axis 33 rotatable on the lock unit 20 stored. The handle 44 has a radial from the axis 33 spaced or off the axis 33 radially extending encoder section 30 on, which with the lock latch 26 is engaged or engageable. Opposite points the latch 44 one also radially from the axis 33 protruding slave section 31 on, which via a first mechanical coupling with an emergency release 40 is in active connection. The first mechanical coupling 43 can be configured in the form of a linkage or in the form of a control cable. About the first mechanical coupling 43 are tensile and / or compressive forces between the emergency release 40 and the lock mechanics 24 or the latch 44 transferable.

As in 2 shown, the emergency release 40 Part of a handle unit 60 his. On the handle unit is also an outside door handle 22 movably arranged. The outside door handle 22 can have a second mechanical coupling 45 also with the lock mechanism 24 be coupled. The mechanical connection of the outside door handle 22 over the second mechanical coupling 45 with the lock mechanism 24 can also be realized via a pawl, for example via a pawl, which is not shown here, realized. The lock mechanics 24 or the lock unit 20 Furthermore, a locking and / or unlocking mechanism 70 have, for example, remote-controlled, electrically actuated or mechanically actuated. The locking and / or unlocking mechanism 70 can be designed to the door lock, in particular the lock mechanism 24 to unlock or lock. In the locked state is the outside door handle 22 almost mechanically from the latch 26 or from the lock mechanics 24 decoupled.

Only in the unlocked state is between the outside door handle 22 and the lock latch 26 one the latch 26 opening mechanical coupling provided as a result of a handle operation. The first mechanical coupling 43 , the emergency unlocking device associated therewith 40 and the latch 44 are independent and mechanically decoupled from the locking and / or unlocking mechanism 70 educated. Regardless of the locking or unlocking the door lock can on the emergency release 40 at any time the latch 44 be mechanically operated and moved to the latch 26 even without operating the outside door handle 22 in the in 3 shown opening position O to convict.

The emergency unlocking device 40 can a lock cylinder 41 have, which is designed to receive a Notentriegelungsschlüssels.
