Definitions

  • the invention relates to a motor vehicle lock, in particular a tailgate lock, with a locking mechanism consisting essentially of a rotary latch and at least one pawl, a release lever, the locking mechanism being unlockable by means of the release lever and a storage element, the locking pawl being at least indirectly by means of the storage element after unlocking the lock is stable in a storage position.
  • the motor vehicle locks used in the flap doors, sliding doors or hoods are equipped with a large number of functions.
  • One of these functions is that, even if a locking mechanism in a motor vehicle is opened, a re-closing or incomplete opening is prevented.
  • the case can occur that after an electrical or manual opening of the lock, the locking mechanism remains in the area of engagement of the lock holder, since the flap with a high load, especially a snow load, is applied.
  • the catch located with the lock holder cannot move completely out of the engagement area of the pawl or swivel out of the area of engagement of the pawl, so that there is a risk that the pawl again comes into engagement with the catch .
  • the snow load function can be integrated into a motor vehicle lock.
  • the disengaged pawl is held during the opening operation in a position in which the pawl is not again can come into engagement with the catch.
  • the disengagement of the pawl is referred to as a storage lever function or snow load function.
  • a Speicherele element is implemented, which is acted upon by a spring.
  • the Spei cherelement is held by the spring in question when opening the associated locking mechanism in contact with at least one lock component. In this way, the functional reliability is to be increased, in particular with a view to the storage element.
  • a structurally simple Ge design is described.
  • GB 2 457 680 A has a spring that works on a release lever.
  • the spring prevents the trigger lever from being pivoted into a first position.
  • the spring is realized as a kind of memory element, but works on the release lever and not on the pawl.
  • the object of the invention is to provide an improved motor vehicle lock.
  • it is an object of the invention to achieve a compact design which ensures high functional reliability with a minimum of components.
  • a motor vehicle lock in particular a tailgate lock
  • a locking mechanism consisting essentially of a rotary latch and at least one pawl, a release lever, the locking mechanism being unlockable by means of the release lever and a storage element, the locking pawl being able to be held in a storage position at least indirectly by means of the storage element after the locking device has been unlocked, and the release lever can be locked in an unlocking position by means of a spring element, so that the locking pawl cannot be latched into the rotary latch.
  • the construction of the motor vehicle lock according to the invention now makes it possible to keep the release lever and thus the pawl out of engagement with the rotary latch.
  • the pawl can be kept out of engagement with the catch. Consequently, the trigger lever is manual or electrically actuated, the spring element comes into a latched position with the release lever, whereby the release lever is held in the unlocked position.
  • the release lever actuates the pawl, so that the pawl is kept out of the pivoting range of the catch at the same time by holding the release lever.
  • the catch can now be opened regardless of a snow load or load on the component to be closed, even if, for example due to a load on a tailgate, the lock holder has not moved the catch out of the locking position. The locking of the rotary latch by means of the pawl can thus be prevented.
  • a motor vehicle lock When speaking of a motor vehicle lock in the sense of the invention, it encompasses locks that are used in hoods, flaps or covers, but also locks that are used, for example, on pivoting doors or on cab locks of trucks.
  • a side door for example, it is also conceivable that, due to an electrically opening mechanism, the locking mechanism has been unlocked, but the door sealing pressure is not sufficient to move the door and thus the locking mechanism out of the locking position and in particular out of a locking position. Also in this Fall can be prevented by the latching of the release lever in the unlocked position, a further engagement of the pawl ver in the rotary latch.
  • the motor vehicle lock has a locking mechanism which has a rotary latch which can be brought into engagement with a lock holder. Due to a relative movement between the catch and lock holder, the catch is wasted and comes into engagement with the spring-loaded pawl.
  • Systems with one or two pawls are used, the pawls preferably being arranged in one plane with the rotary latch. However, it is also conceivable that two pawls can be used, for example, for a preliminary catch and for a main catch.
  • the Pawl have an opening moment due to the structural arrangement and the load of the rotary latch, so that the pawl is to be held in engagement with the rotary latch by means of a second pawl. Such a second or further pawl is also referred to as a blocking lever.
  • the release lever is pivotally arranged in the motor vehicle lock and is able to unlock the locking mechanism.
  • the release lever and the locking parts are pivotally received in one plane and preferably on a lock plate of the motor vehicle lock.
  • the spring element is advantageously a leg spring, the leg spring being accommodated in a stationary manner in the motor vehicle lock.
  • the use of a leg spring offers the possibility of using an inexpensive component with high functionality.
  • the legs of the leg spring can serve as stops but also as a means for introducing a force into a moving component.
  • the design of the spring legs enables safe and permanently elastic locking.
  • both spring legs of the leg spring can be provided with a function in order to enable interaction with other components as well as the release lever.
  • a movable component can be preloaded with a force on the one hand and a spring leg can serve as a latching means for the release lever on the other hand.
  • the leg spring can be snapped into a contour of the release lever. If the release lever has a locking contour, then a secure locking can be achieved by means of the spring leg.
  • the latching contour can be formed on the release lever in such a way that when the locking mechanism is unlocked by means of the release lever, one leg of the Leg spring comes into engagement with the locking contour. This creates the possibility of safely positioning the release lever, which in turn increases the functional reliability of the motor vehicle lock.
  • the contour of the release lever is arranged in a through opening of the release lever. The passage of the spring leg of the leg spring through a through opening in the release lever reduces the installation space, since the locking contour can be moved into the interior of the pawl.
  • the through opening can extend circumferentially over the release lever, the fixed leg spring and in particular a particular leg protruding into the opening and preferably abutting a radial end of the opening of the release lever. If the release lever is now pivoted in the opening direction, a recess or depression in the opening can serve as a locking contour for the spring leg.
  • a sharp edge in the area of the snap-in contour can provide a high degree of snap-in security, whereby a gentle and light, that is, for example, oblique transition into the snap-in contour enables a quiet, that is, low-noise, engagement of the spring leg.
  • the locking mechanism has a further pawl, in particular a blocking lever
  • a further embodiment variant of the invention results.
  • the use of a further pawl offers the advantage that the first pawl can be designed with an opening moment on the rotary latch. The pawl then holds, as already described above, the locking position by the locking lever.
  • the use of the memory function according to the invention by means of latching the release lever can be used particularly advantageously here because it has been shown that the release lever only slight forces have to be overcome in order to disengage the blocking lever from the pawl and possibly almost or almost no forces are required to move the pawl out of the swivel range of the rotary latch.
  • a locking mechanism with two pawls is thus advantageously suitable for the storage function according to the invention.
  • the leg spring is received on an axis of the further pawl, the leg spring being in engagement with the blocking lever.
  • the leg spring can be accommodated in a space-saving manner in a stationary manner, for example on an axis of the further pawl. As a result, a minimum of installation space is required to position the leg spring.
  • the Federele element therefore has an additional function, namely that the blocking lever can be pretensioned in the direction of the pawl by the leg spring.
  • the storage and the introduction of force into the blocking lever serves as a counter bearing for another leg which can be brought into engagement with the release lever.
  • the leg spring thus serves to introduce a force and at the same time serves as a latching means to achieve a storage function.
  • the release lever has a first control contour for actuating the blocking lever and a second control contour for actuating the pawl, a further embodiment variant of the invention results.
  • the Auslteilhe bel is preferably constructed in one piece and provided from a metallic base body with an at least partially plastic sheathing. Consequently large forces can be transmitted using the release lever and at the same time the pawls can be operated with little noise.
  • the formation of control contours on the release lever makes it possible to disengage the white pawl as well as the pawl which is engaged with the catch.
  • a first control contour moves the blocking lever when the release lever is actuated, so that the pawl is released.
  • the pawl Due to the pressure force exerted on the pawl by the rotary latch, the pawl can move out of the engagement area with the rotary latch independently.
  • a second control contour as a kind of securing means, engages with the pawl and moves the pawl out of engagement with the rotary latch.
  • the leg spring locks the release lever and keeps the blocking lever and pawl out of engagement with the range of motion of the rotary latch. The catch can now be opened at any time.
  • release lever can be unlocked by means of the rotary latch, there is a further advantageous variant of the invention.
  • the release lever is in the actuated position in the locked unlocked position or open position and holds the pawls in the memory function. If the rotary latch is now fully opened, the opening movement of the rotary latch can advantageously be used to unlock the release lever. Consequently, no further components are necessary to enable unlocking of the release lever.
  • the leg of the leg spring which can be brought into engagement with the release lever can be actuated by means of the catch and in particular by means of a control contour on the catch, which corresponds to a further embodiment variant of the invention.
  • a control contour on the rotary latch comes into engagement with the leg of the leg spring when the rotary latch has moved so far in an opening direction that the pawl no longer can engage in a locking surface of the rotary latch.
  • the pawl then comes to rest with a contact surface on an outer contour of the rotary latch.
  • the release lever is released and consequently is no longer held in the unlocked position by the leg of the leg spring.
  • the control contour can be formed, for example, from an increase on the rotary latch.
  • control contour on the rotary latch is formed by a plastic coating of a steel core of the rotary latch.
  • a cost-effective way of providing a control contour is thus possible.
  • No further components are required to unlock the release lever, which minimizes the number of components and at the same time ensures a compact design.
  • the latching of the release lever by means of the multifunction spring or the leg spring provides a maximum of security in order to achieve a memory function.
  • FIG. 1 shows a plan view of a locking mechanism designed according to the invention with the components essential for the explanation of the invention in a main detent position and
  • FIG. 2 is a plan view of the locking mechanism according to the invention according to FIG. 1 in an open position.
  • FIG. 1 shows a side view of a motor vehicle lock 1 designed according to the invention with the components essential for the invention.
  • the motor vehicle lock 1 comprises a locking mechanism 2 consisting of a rotary latch 3, a pawl 4, a further pawl 5 and a release lever 6. Between the release lever 6 and the further pawl 5, a leg spring 7 is arranged, the leg spring 7 on an axis 8 the further pawl 5 is added.
  • the locking mechanism 2 and the release lever 6 are pivotally mounted in the motor vehicle lock 1 and preferably on a lock plate 9.
  • the rotary latch 3 is about the axis 10, the pawl 4 about the axis 11 and the release lever 6 about the axis
  • the leg spring 7 has two spring legs 13, 14, with a first spring leg 13 with the further pawl 5 and a white spring leg 14 with the release lever 6 is engaged.
  • the spring leg 14 extends through an opening 15 of the trigger lever 6 through into the pivoting range of the rotary latch 3.
  • the locking mechanism 2 is shown in a anti-lock position, with a locking surface 16 on the catch 3 engaging with a locking surface 17 on the pawl 4.
  • the anti-lock position of the locking mechanism 2 is designed such that an opening moment acts on the locking pawl 4, as a result of which the locking mechanism 2 would open automatically without the additional locking pawl 5.
  • the further pawl 5 can thus also be referred to as a blocking lever 5.
  • the locking mechanism 2 is shown in a anti-lock position, in which a lock holder 18 is held in the motor vehicle lock 1 by means of the locking mechanism 2.
  • the release lever 6 is pivoted in the counterclockwise direction in the direction of the arrow P1, the blockade lever 5 also being released in the counterclockwise direction in the direction of the arrow P2 by the pawl 4.
  • An extension 19 on the release lever 6 engages a bolt 20 of the blocking lever 5.
  • Another extension 21 with another bolt 22 engaged and wasted pawl 4 also counterclockwise in the direction of arrow P3.
  • the movement of the release lever 6 causes the spring leg 14 to engage with a contour 23 of the opening 15, as a result of which the release lever 6 locks in its open position.
  • the opening position of the release lever 6 is shown in FIG. 2.
  • the locking surface 24 is a locking surface for pre-locking the locking mechanism 2.
