Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, further with a working on the locking mechanism lever mechanism, and with a locking element which interacts with a spring and the operating lever mechanism occurring acceleration forces of predetermined size (crash) interrupts and closes in normal operation to the opening of the locking mechanism.
- centrifugal forces or corresponding mass barriers acted upon motor vehicle locking systems or motor vehicle door locks are known in many ways. Essentially, it is important to prevent inadvertent opening of the vehicle door equipped with the motor vehicle door lock in question during strong accelerations, as occur, for example, in the event of a crash. This is the only way to ensure that the occupants in the motor vehicle are maximally protected and, for example, safety devices such as side airbags, etc. in the vehicle door unfold their effect precisely.
- Active systems are characterized by the fact that movement takes place both in the event of strong and low acceleration of the lock kinematics or of the motor vehicle door lock and in particular of the actuating lever mechanism, in order to achieve a secure functional capability over the entire service life.
- passive systems react only at unusually high acceleration, that is, in the event of a crash. All previously known centrifugal force or mass barriers to prevent unwanted door opening in the event of a crash require additional components that increase the weight of the vehicle door and the cost.
- EP 2 133 496 A2 the associated outside door handle with a as
- a corresponding handle can only be operated in a release position of the mass lock or the pivotable locking member. In the event of a crash, the handle is blocked. Due to the necessary and relatively complex constructed locking member not only the mass of the known outside door handle is significantly increased, but also not inconsiderable costs associated with this.
- the functional element is connected to the spring-elastic component in question, which extends at impact load. Due to the change in length of the spring-elastic component, the functional element displaces into a position which blocks or disengages the movement of the pawl. In this way, a crash barrier is to be developed in summary, which reacts to forces in a three-dimensional space and is easy to position.
- the invention is based on the technical problem of further developing a Kraftchristfschioss of the structure described above so that with perfect functionality costs and weight compared to previous designs are reduced.
- the present invention proposes in a generic Kraftchristfschioss that the locking element elastically deforms the spring in the event of a crash with continued interruption of the operating lever mechanism and in normal operation on the spring along slides to close the operating lever mechanism.
- the spring in the present invention is expressly not mechanically connected to the blocking element. Rather, the locking element on the one hand and the spring on the other hand are designed separately from each other. While the locking element, for example, in a lock housing, so a lock case and / or lock cover, is rotatably mounted and with the aid of, for example, a bolt anchored in the lock case for supporting the locking element is defined a rotation axis, the spring has in contrast via a stationary attachment. This can also be in the lock case.
- the spring can be advantageous altogether advantageously a leg spring.
- This leg spring encloses with its turns the questionable bolt, so that at least one free leg protrudes from the bolt. That is, the spring advantageously has at least one elongate free leg.
- the blocking element works.
- the blocking element is usually equipped as a multi-arm lever with at least one stop arm and a release arm.
- the blocking element is a three-arm lever, which in addition to the stop arm and the trigger arm still has a rotating arm.
- the stop arm is at rest on a housing-fixed stop.
- the release arm interacts with the spring or the elongated free leg of the leg spring.
- the trigger arm abuts against said leg of the spring.
- the design is usually made such that the blocking element rests with its release arm at most acute-angled to right angles to the free leg of the spring.
- the free leg of the spring extends tangentially or predominantly tangentially in comparison to the release arm of the blocking element.
- the design is always such that the spring or the free leg of the spring is compressed in the event of a crash or during the acceleration forces of predetermined magnitude occurring in this case, the actuating lever mechanism being interrupted continuously. That is, the blocking element in conjunction with the spring in the said crash case ensures that the actuating lever mechanism is disengaged and remains with respect to the locking element to be acted upon. As a consequence thereof is in the said crash case, a continuous mechanical connection of the operating lever mechanism up to the locking mechanism is not available, so that the operating lever mechanism is interrupted and the locking mechanism can not open.
- the normal operation corresponds to the fact that the spring or its free spring leg is not deformed or practically not elastically deformed by the triggering arm of the locking element abutting thereon.
- the forces exerted by the blocking element on the spring in normal operation are insufficient.
- the blocking element slides in the relevant normal operation along the spring and undergoes a pivoting.
- This pivoting is accompanied by a coupling process of the actuating lever mechanism with respect to the locking mechanism. That is, the sliding movement of the locking element in normal operation along the spring ensures in effect that the operating lever mechanism is closed or engaged.
- the blocking element may work on a coupling member or generally a connecting element in the operating lever mechanism in a corresponding sense.
- the second alternative corresponds to the fact that the blocking element a quasi
- the replacement blade represents an integral part of the operating lever mechanism and immediately the operating lever mechanism interrupts (in the event of a crash) or closes (in normal operation). In order to keep the number of components low and consequently to work with the lowest possible cost, it is usually worked according to the latter variant.
- the blocking element is integrated in the actuating lever mechanism or forms part of the actuating lever mechanism or is ultimately designed and arranged such that the blocking element is located between the actuating lever mechanism and the locking mechanism. In this case, the blocking element can take over the function of a transmission lever or release lever for the locking mechanism.
- the blocking element In addition to this quasi-dual functionality of the blocking element on the one hand as a mass barrier and on the other hand as a release lever or triggering element for the locking mechanism, another functionality of the blocking element can be realized within the scope of the invention.
- an additional locking unit to Beraufschlagung of the blocking element in question may be provided.
- the locking unit typically works by means of a coupling lever on the blocking element.
- the locking unit ensures that the blocking element is blocked by motor in the "locked” position.
- the position or functional position "unlocked” corresponds to the fact that the locking unit allows the blocking element a freewheel.
- the blocking element can be equipped with a further third function.
- the functional positions "locked” and “unlocked” of the motor vehicle door lock according to the invention can be mapped. That is, the blocking element takes over
- the invention does not require a separate blocking element, but according to the invention the blocking element takes over the function of the triggering lever or locking lever.
- the blocking element, the release lever and the locking lever ultimately merge into the blocking element according to the invention. This reduces weight, facilitates assembly and leads to significant cost savings.
- the locking element slides along the spring to close the actuating lever mechanism - provided that the optional locking unit and thus the motor vehicle door lock is “unlocked” in its entirety.
- the spring thus ensures that the blocking element is engaged in normal operation with respect to the operating lever mechanism and there is a continuous mechanical connection up to the locking mechanism to its opening. Since the spring supports this engagement, low actuating forces can be expected for the actuating lever mechanism.
- the blocking element according to the invention is designed little massive and is ultimately engaged by means of the spring. That is, the spring supports the engagement operation in the normal operation, so that no increase in the operation force is observed.
- the motor vehicle door lock according to the invention is equipped with increased functional reliability. Because the blocking element is in the
- the locking unit may independently provide for a pivoting of the locking element. This applies in particular to the case in which the locking unit is a central locking unit.
- the invention is based on the recognition that the blocking element is typically “locked” in its position.
- This position “locked” can be defined or frozen with the help of the locking unit. This is ensured by the clutch lever which, with a blocking pin, blocks the locking element in the "locked” position if the locking unit moves the clutch lever accordingly.
- the functional position “unlocked” corresponds to the locking unit to the fact that the clutch lever is transferred to a position in which its blocking pin allows a freewheeling of the locking element.
- 1 shows the motor vehicle door lock according to the invention schematically, partially dash-dotted in a normal operation
- a motor vehicle door lock in the event of a crash.
- a motor vehicle door lock is shown, which initially has a lock housing 1.
- the lock housing 1 may be a lock case or a lock cover which together serve for the storage and housing of the components to be described below.
- a locking mechanism 2, 3 from a rotary latch 2 and a cooperating pawl 3 is mounted in the lock case or lock housing 1.
- a bolt 4 defines an associated axle 4 for pivoting the rotary latch 2
- a bolt 5 defines a further axle 5 for the pawl 3 or its pivotal movements.
- the external actuating lever 6a, 6b is composed of the two lever sections 6a, 6b which are connected to one another in an articulated manner via a bolt 7.
- the two lever portions 6a, 6b are pivotally connected to each other via the bolt 7 and are biased by means of a spring 7 connected to the bolt 7 in a clockwise direction, as a corresponding arrow in Fig. 1 indicates.
- An associated stop fixed to the housing 10 in this connection ensures that the lever section 6a is not moved towards the lever section 6b by the force of the spring 8.
- the external operating lever 6a, 6b can also be designed in one piece.
- the operating lever mechanism 6a, 6b or the external actuating lever 6a, 6b is acted upon by means of an outside door handle 9.
- a pulling movement of the user ensures that the outside door handle 9 in question acts on the actuating lever mechanism 6a, 6b at its associated end in the direction of the arrow.
- a pivoting movement of the external actuating lever 6a, 6b about its axis or axis of rotation 15 corresponds.
- the external operating lever 6a, 6b is considered as an example only. Instead of the external actuating lever 6a, 6b, a correspondingly designed and designed internal actuating lever could just as well be provided
- both an inside operating lever mechanism and the illustrated external operating lever mechanism 6a, 6b are realized as operating lever mechanism 6a, 6b.
- the locking unit 11, 12 is composed of a motor or electric motor 11 on the one hand and a driven pulley 12 on the other hand together.
- the electric motor 11 operates with its output shaft via a worm there provided on the driven pulley 12 and can pivot them depending on the direction of rotation of the output shaft in the clockwise direction or in the counterclockwise direction. As a result, performs a connected to the driven pulley 12 clutch lever 13 corresponding linear movements.
- the locking unit 11, 12 In the position shown in phantom of the coupling lever 13 in FIG. 1, the locking unit 11, 12 is in its position "unlocked". In fact, in the "unlocked" position of the locking unit 11, 12 and consequently of the motor vehicle door lock, the clutch lever 13 as a whole permits free-wheeling of a locking element 14 which will be considered in detail below. That is, in the dash-dotted position of the clutch lever 13 in Fig. 1, the blocking element in question 14 perform a pivoting movement such that the locking element 14 at the end of this pivoting movement, which also indicated by dash-dotted lines position in FIG. In this dot-dashed position, the blocking element 14 is able to lift the pawl 3 from the catch 2 and consequently to open the locking mechanism 2, 3.
- the blocking pin 13a prevents the locking member 14 can be pivoted to the previously treated dot-dash position. Only in this dash-dotted position, the blocking element 14 is able to interact with the locking mechanism 2, 3 to its opening. In contrast, the locking element 14 on the one hand and the pawl 3 on the other hand in the position "locked” out of engagement.
- the already discussed locking element 14 is presently designed as a multi-arm lever 14. In fact, the blocking element 14 or the multi-arm lever 14 has a stop arm 14a and a release arm 14b.
- a rotary arm 14 c is additionally provided, which defines the associated axis or axis of rotation 18 of the locking element 14 in conjunction with a bolt 18.
- the external operating lever 6a, 6b is pivotally connected via a bolt 15 to the blocking element 14.
- the locking element 14 interacts with a housing-fixed spring 16.
- the spring 16 is a leg spring, which is equipped in the embodiment with an elongated free spring leg 16a.
- Another spring leg 16b ensures that the spring 16 is anchored in the lock housing 1.
- one or more turns of the leg spring enclose a bolt 16c anchored in the lock housing 1.
- the blocking element 14 interacts with the spring 16 in such a way that in the case of acceleration forces F of a predetermined magnitude shown and occurring in FIGS. 2A to 2C or in the event of a crash, the actuating lever mechanism 6a, 6b is interrupted. That is, the locking element 14 ensures that in the event of a crash according to FIGS. 2A to 2C and the acceleration forces occurring there
- FIGS. 2A to 2C corresponds to the fact that the blocking element 14 with its triggering arm 14b elastically deforms the spring 16. At the same time there is a continued interruption
- the blocking element 14 in normal operation perform the pivoting movement shown in FIG. 1 from the solid to the dash-dotted position. Because in normal operation, the operating lever mechanism 6a, 6b in its counterclockwise movement about the axis or the bolt 15 by acting on the outside door handle 9 in a position to "take along" the locking element 14 as it were. During this entrainment, the release arm 14b of the blocking element 14 slides along the free leg 16a of the spring 16 and, guided by the stop 17, following the movement of the actuating lever mechanism 6a, 6b, can pivot about the axis 18 counterclockwise.
- the blocking element 14 assumes the dot-dashed position in FIG.
- the operating lever mechanism 6a, 6b further applied in the direction indicated by an arrow in Fig. 1 opening direction by pulling the outside door handle 9, this further movement causes the locking element 14 from the dot-dashed line position in FIG. 1 a slight Pivoting movement in a clockwise direction about the axis 18 performs.
- the blocking element 14 with its release arm 14b is capable of locking the pawl 3 in the counterclockwise direction as described.
- the spring forces applied by the spring 16 prevent such clockwise movement of the blocking element 14 and ensure that the trigger arm 14b slides along the free leg 16a of the spring 16.
- the trigger arm 14b of the blocking element 14 moves in normal operation and in the "unlocked" position from its solid to the dot-dashed position according to FIG. 1.
