Definitions

  • the invention relates to a lock for a motor vehicle having the features of the preamble of claim 1.
  • An initially mentioned lock comprises at least one usually made of metal lock plate (also called lock case) with a mounted thereon locking mechanism.
  • the lock plate is usually provided with an inlet slot for receiving a locking bolt.
  • the locking mechanism comprises a rotatably mounted rotary latch for receiving a locking bolt.
  • the locking mechanism further has a pawl with which the catch can be locked.
  • the catch of a motor vehicle lock usually has a bifurcated inlet slot formed by load arm and catching arm into which the locking bolt of a vehicle door or flap, for example bonnet or trunk lid, comes when the door or flap is closed.
  • the locking pin then rotates the catch from an open position to a closed position. If the catch has reached a corresponding closed position, it is locked in this position via the pawl.
  • the locking bolt can not leave the inlet slot of the rotary latch.
  • This detent position is called main detent position or main detent position.
  • pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing.
  • the rotary latch in the pre-locking position, the rotary latch is not completely closed, but an opening movement of the rotary latch is already prevented by a pawl. That is why the area of Rotary latch, which receives the pawl in this position, referred to as a pre-detent.
  • the pre-restraint thus represents a transition state between the opened state and the main rest and is provided for safety reasons.
  • the locking pin exerts a corresponding pressure on the load arm. Since the load arm is connected to the rotary latch axis, a corresponding force is transmitted to the rotary latch axis.
  • the stress can also affect the pawl. In a conventional lock, therefore, the individual parts of a locking mechanism are built so stable that they can cope not only with the daily operation, but also sudden impact stresses.
  • the object is achieved by providing a lock with a lock case and a locking mechanism comprising a rotary latch with a load arm and a catch arm, which is rotatably mounted by means of a rotary latch axis.
  • the catch can take a locking pin.
  • the locking mechanism has a pawl for locking the catch.
  • a pivotable power transmission latch is provided, with which a transmitted by a locking pin on the load arm force can be routed out of the locking mechanism and transmitted to the lock case, for example.
  • the pivotable power transmission bolt is arranged in particular so that, in particular, the rotary latch axle is relieved.
  • the power transmission bolt is therefore basically on the side of the inlet slot of the lock box on which the rotary latch axis is located.
  • the power transmission bolt is in the open position of the lock or the locking mechanism in a rest position. Rest position means that then the power transmission bolt is unable to conduct forces out of the locking mechanism and transfer it to another component such as the lock case. It is further provided that the power transmission bolt is pivoted in the main locking position of the locking mechanism in such a position that the power transmission bolt is able to derive excessive forces from the locking mechanism. This situation is called "power transmission position" below.
  • the necessary pivotal movements of the power transmission bar can be realized by springs or other mechanical solutions or electronically or magnetically triggered and / or controlled.
  • a power transmission bolt of a motor vehicle lock is already in the non-prepublished German patent application with the official file number 10 2009 029 025.7 described. All features and designs of this German Patent application known lock may in principle also include the claimed with this patent application lock.
  • the now claimed lock differs from that of the German patent application with the official file number 10 2009 029 025.7 However, known lock with respect to the rest position of the power transmission bolt. In the rest position, the power transmission bolt is in contrast to that from the German patent application with the official file number 10 2009 029 025.7 known teaching outside the plane in which the catch is rotated, ie above or below the catch to allow a particularly space-saving design.
  • the use of the pivotable power transmission bolt to transmit excessive forces, such as may occur in a crash, from the ratchet on, for example, the lock box allows the interpretation of the locking mechanism on the forces occurring in daily use while the presence of emergency reserves for emergency (crash), since the forces are then transferred to the lock case or another external component and not alone on the catch, the rotary latch axis and possibly the pawl.
  • the cost of materials for the lock can be reduced as a whole.
  • An inventive lock can therefore be advantageous overall small and built with less weight.
  • the power transmission bolt is preferably pivotally mounted such that the catch is able to pivot the power transmission bolt away from its power transmission position by a rotational movement from a closed position to the open position. If the power transmission bolt has been pivoted away in this way, then in one embodiment of the power transmission bolt is above or below the Lastarms of the catch and seen from the base of the lock plate, which basically has the inlet slot for the locking pin. In particular, is located the power transmission bolt then below the catch and thus below the load arm, because then the pivot or rotation axis of the power transmission bolt can be attached to the base of the lock plate and this is no additional component to provide. This represents a particularly simple, more space-saving design.
  • the axis of rotation of the power transmission latch preferably extends at least substantially parallel to the inlet slot of the latch box.
  • the power transmission bolt is pivotally mounted so that the catch is able to pivot the power transmission bolt away from its power transmission position as described above, there is advantageously a biased spring element capable of pivoting the power transmission bolt back into its power transmission position.
  • the power transmission bolt is moved in this embodiment by the spring in its power transmission position when the catch is rotated from its open position towards the closed position and therefore releases the power transmission bolt.
  • a substantially metal existing load arm which may have a sheath made of plastic, a nose made of plastic, which against the Power transmission bar abuts and pivots this when the catch is rotated from a latched position to the open position. Opening noises are minimized.
  • microswitch actuated by the pivoting of the power transmission bar.
  • the microswitch is used for control purposes, such as turning on interior lighting of the vehicle when the catch is not in the main latching position.
  • the micro-switch can also be used to activate a warning signal when the power transmission latch is not pivoted into its power transmission position, even though the catch has reached its main detent position. This embodiment makes it possible to easily display a fault.
  • a microswitch and other detector means can be used, which are able to signal a pivoting of the power transmission bar in a selected position.
  • a detector means may for example be a proximity sensor capable of signaling an approach of the power transmission bar or a part of the power transmission bar.
  • the power transmission latch is connected to a lever arm with which a microswitch or other detection means is actuated or triggered when the power transmission latch is pivoted.
  • the lever arm is arranged so that it is pivoted through an opening of the lock plate, when the power transmission bolt is pivoted to its rest position.
  • a microswitch or other detector means actuated or triggered by the lever arm may then advantageously be arranged on the side of the lock plate opposite the ratchet. The lock plate then separates so the locking of electrical or electronic components that are able to signal the position of the power transmission bolt.
  • the lock comprises a lever capable of acting on the power transmission latch, hereinafter referred to as "control lever".
  • the control lever comprises a first lever arm which is moved starting from a starting position, in particular by the locking pin, when the rotary latch is rotated by the locking bolt in the direction of the main locking position.
  • the control lever comprises a second lever arm. If the first lever arm is moved together with the rotary latch in the direction of the main latching position, then the second lever arm can detect and move the pivotable power transmission latch so that the power transmission latch is pivoted into its power transmission position. Alternatively or additionally, the second lever arm reaches such a position that, in the main locking position of the locking mechanism of the power transmission bolt, it is prevented by the second lever arm from pivoting back into its rest position. The reliability of the lock is improved.
  • the control lever which is capable of acting on the power transmission latch, includes means for moving the control lever to its home position when the latch is opened.
  • Such means may be a spring which moves the power transmission latch to its home position when the latch is released or the lock is opened.
  • This means may alternatively or additionally comprise a third lever arm, which is preferably moved by the locking pin when the locking mechanism is released and the locking pin is moved out of the locking mechanism.
  • the second lever arm is prevented from moving by the power transmission latch when, for example, the power transmission latch can not be pivoted into the power transmission position by a spring or a correspondingly acting means due to damage. A door or flap can then no longer be properly closed. A corresponding damage does not go unnoticed in this embodiment.
  • the catch comprises a main catch and a pre-ratchet.
  • the first lever arm of the control lever is then preferably dimensioned and is thus rotated together with the catch during a closing operation, that a pawl initially can not lock into the pre-catch. It is the closing process otherwise occurring noise from the non-prepublished German patent application with the official file number 10 2008 046 931.9 avoided mentioned reasons.
  • the corresponding lever is referred to in this German patent application as Vorrastunterdschreibungshebel.
  • the known advantageous embodiments of the Vorrastunterdschreibungshebels known therefrom can in principle also be embodiments of the now claimed lock.
  • the control lever is thus in one embodiment, at the same time a Vorrastunterdschreibungshebel.
  • a pawl of the locking mechanism in the main latching position prevents the control lever from being able to reach its starting position, from which the control lever is able to move the power transmission latch into its power transmission position.
  • the control lever can only be pivoted or rotated to its initial position when the pawl is pivoted away.
  • the pawl which locks the catch in the main latching position, at the same time the pawl, which prevents the control lever from being turned back or pivoted in the main latching position to its initial position.
  • a preloaded compression spring which is able to move the control lever in its two end positions.
  • the second lever arm of the control lever presses against the power transmission bolt and thus contributes to the fact that the power transmission bolt is reliably held in its power transmission position.
  • the other end position is the aforementioned starting position.
  • the control lever is, for example, in its initial position and this is rotated by means of a locking pin in the direction of its other end position, the lever reaches a reversal point, from which the biased compression spring pushes the control lever in its other end position.
  • control lever If the control lever is in its other end position and the control lever is rotated, for example, by means of a locking bolt in the direction of its initial position, the lever in turn reaches said reversal point, from which the prestressed compression spring then pushes the control lever into its initial position.
  • the control lever is always moved completely into its respective end position and does not move out of such an end position unscheduled out. This will be the Operational safety of the locking further improved.
  • the control lever is also designed as Vorrastunterd Wegungshebel, so it is ensured that the control lever during the closing of an associated vehicle door or vehicle door can not be unintentionally turned back together with the catch in the open position when the main detent position is not reached. The possibility of latching in the pre-locking position is thus improved.
  • the rotary latch comprises a stop for the control lever.
  • This stop is arranged so that it can additionally ensure that the control lever is moved in the direction of the starting position when the locking mechanism is unlatched. This embodiment ensures that the control lever can be moved back to its initial position even if the locking mechanism has been latched without a locking pin in the inlet slot.
  • the lock is designed so that a pivoting of the power transmission latch in its rest position detects the control lever and moves in the direction of the starting position.
  • This embodiment provides as an alternative or in addition to the aforementioned embodiment, that the control lever can be moved back to its initial position even if the locking mechanism has been locked without a locking pin is in the inlet slot.
  • control lever there is a stop for the control lever.
  • the control lever reaches this stop when it has been fully moved into its home position.
  • the control lever is advantageously made of plastic to keep the weight of the lock low.
  • control lever which acts on the power transmission bar, is also advantageous when the power transmission bar as described can be pivoted back and forth between two positions for the reasons mentioned above, but the rest position of the power transmission bar is not outside the plane within which the catch can be turned.
  • the control lever can therefore be the subject of an independent invention, which does not comprise all the features of claim 1.
  • the lock case or the lock plate is preferably constructed in two parts.
  • the lock case comprises a metallic plate on which the catch and the pawl are rotatably mounted.
  • the locking mechanism comprises a control lever, it is preferably also rotatably mounted on the metallic plate.
  • the lock case is made of plastic to minimize the weight of the lock.
  • the plastic part of the lock case is preferably fixedly connected to the metallic plate, for example by means of a screw, rivet and / or adhesive connection. Should it be expedient for reasons of stability, for example, then the lock case is made entirely of metal.
  • the metallic plate of the lock case preferably extends angularly around the inlet slot of the lock case. At one end of the angle, the pawl of the locking mechanism is rotatably mounted and at the other end the catch. The metallic part of the lock case and thus its weight are minimized.
  • Lock box width means the extent of the lock case along the inlet slot of the lock case. What is meant by lock case width is also clear from the embodiments described below.
  • the pivotable power transmission bolt is in particular attached to the lock case and / or arranged so that it extends from a side wall of the lock case in the main latching position to the catch. This lateral wall adjoins the lock box entry slot for the lock bolt at a right angle.
  • the power transmission bolt is arranged in particular adjacent to the inlet slot of the lock case, and preferably on the side of the inlet slot on which the rotary latch axis is arranged. In the main locking position, the power transmission bolt then adjoins the rotary latch in such a manner that the rotary latch is pressed against the power transmission bolt in the case of the abrupt stresses described. The power transmission bolt then absorbs the corresponding force and forwards it to the lock case, and indeed because of its attachment and / or due to its support on a corresponding side lock case wall.
  • the power transmission bolt may be wholly or partly made of metal and of the same or a different material as the Be made catch.

  • the power transmission bolt in the installed state of the lock can always also be supported on a wall of the vehicle in order to transfer forces from the locking mechanism to other components in the main latching position, for example into a vehicle door or vehicle door.
  • the power transmission bolt is preferably arranged within the lock case. Particularly preferably, it is arranged in spatial proximity to the rotary latch axis, very particularly preferably in spatial proximity to the load arm, in particular in spatial proximity to the load arm and the rotary latch axis. Such arranged power transmission bar basically requires no additional space.
  • the power transmission bar touches the catch, preferably the load arm of the catch only when due to strong forces, the catch is moved in the main latching position in the direction of power transmission bolt. It is thus advantageously avoided the occurrence of frictional forces during normal operation due to a regular contact between the rotary latch and power transmission.
  • the distance between the power transmission bolt and the rotary latch is chosen so small that the rotary latch axle can not be deformed so that it breaks before the catch is supported by the power transmission bar.
  • the power transmission bolt is preferably cuboid, since the available space can then be used optimally. But there are also other Krafttragungsriegelgeometrien, such as Example rod-shaped or crescent-shaped embodiments used.
  • the power transmission bolt is in the main detent position of the rotary latch in spatial proximity to the load arm, particularly preferably the power transmission latch enters a bulge of the load arm so as to maintain its position particularly reliably when high forces are transmitted from the rotary latch to the latter.
  • Either the power transmission bolt can be particularly firmly anchored to a lock case wall on which it is for example mounted movably, for example by a guide or rivet and / or it can touch both the load arm and at least one lateral lock case wall in the main load position of the catch at high load ,

  • the catch can be completely or partially encased in plastic. Individual components of the rotary latch, in particular the catch arm, which is comparatively slightly loaded even in crash situations, can be used partially or completely made of plastic, to make the lock easy and inexpensive.
  • the pawl may be formed of metal or plastic. Preferably, however, it is made of metal.
  • both the pre-rest and the main rest is performed on the load.
  • This allows a construction of the tentacle with low weight and contributes to the weight reduction and compactness of the overall construction.

  • the projection 8 of the pawl 3 prevents in the main latching position the control lever to get to its starting position. Should the control lever unintentionally want to rotate to its original position, then the end of the first lever arm 16 abuts against the projection 8, which prevents the continuation of the rotational movement.
