Definitions

  • the invention relates to a motor vehicle door lock, in particular a motor vehicle front hood lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, which interacts with a lock holder bracket on a hood, and with a memory element which holds the pawl in a storage position lifted from the rotary latch when the hood is unlocked holds.
  • Motor vehicle door locks and in particular motor vehicle front hood locks are known in various embodiments from practice and are exemplified in the DE 199 38 687 B4 described.
  • This is a so-called catch hook lock which, in addition to a pawl to secure the rotary latch of the locking mechanism, also has a catch hook.
  • the catch hook in question is pivoted into its closed position in which it engages behind the locking bolt or lock holder bracket.
  • the locking bolt or lock holder bracket is thus secured twice, on the one hand by the rotary latch held in the closed position with the aid of the pawl and on the other hand by the aforementioned catch hook.
  • the unlocking / opening device In order to open such a hook lock, the usual practice in practice is to provide an unlocking / opening device to act on the locking mechanism.
  • the unlocking / opening device generally has a handle provided in the interior of a motor vehicle body. With the help of the handle, the lock can be unlocked and opened.
  • a closing device for a front hood in which the hood can be opened simply by actuating an actuating lever twice inside the motor vehicle.
  • This is intended to provide a particular suitability for front hoods of motor vehicles.
  • the solution proposed for this purpose makes use of, among other things, a drive for a rocker arm, with the aid of which the locking mechanism can be moved completely or partially so that a door gap or hood gap can be reduced or enlarged.
  • the actuation device for unlocking the locking mechanism is also equipped with a clutch. This results in a relatively expensive and complicated mechanical construction, which under certain circumstances can lead to functional impairments.
  • the procedure is such that the motor vehicle door lock there has a release element for the locking mechanism and a memory element is equipped.
  • the storage element ensures an unimpeded opening movement of the rotary latch from a closed to an open position.
  • the storage element holds the release element during the opening movement of the rotary latch in an ineffective position with respect to the locking mechanism.
  • the release element is assigned a blocking lever that interacts with the pawl. In this way, the greatest possible functional reliability is to be made available with a structurally simple structure.
  • a comparable prior art describes the DE 10 2006 032 033 A1 , in which the storage element ensures that in the storage position the pawl is held in its release position when the rotary latch is turned out of its closed position until it has passed the storage position.
  • a motor vehicle door lock with a locking mechanism consisting of a rotary latch and a pawl that interacts with a lock holder bracket, and with a memory element that holds the pawl in a storage position lifted from the rotary latch during an unlocking process, the lock holder bracket still falling into the rotary latch in the storage position and during a first opening process starting from the storage position, the storage element is transferred into a release position that releases the pawl.
  • hood or front hood can be opened as part of the unlocking / opening device for the locking mechanism simply by operating an actuating lever or the handle.
  • a double-click is usually used, as was the case previously mentioned DE 10 2014 012 112 A1 describes.
  • the invention aims to provide a remedy here overall.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that the functional reliability is increased while at the same time being structurally simple.
  • the lock retainer bracket arranged on the hood in the storage position continues to fall into the rotary latch and the storage element is transferred to a release position releasing the pawl in a first opening process starting from the storage position. In this way, during a subsequent closing process of the hood, the pawl can fall into the rotary latch which can be pivoted into the storage position without force from the lock holder bracket.
  • the procedure within the scope of the invention is such that the locking mechanism is acted upon with the aid of an unlocking / opening device.
  • the unlocking / opening device typically has a handle provided inside the motor vehicle body. At a first When the handle is operated, the locking mechanism is generally transferred into a pre-latching position. In this pre-locking position, the lock retainer bracket is still like held and secured in front of with the help of the rotary latch and the pawl located in the preliminary position. The same goes for the hood.
  • hood in the context of the invention includes any flap element on or in a motor vehicle, i.e. not just a front hood, but also a motor vehicle door, a motor vehicle side door, a tailgate, a trunk lid and even a fuel filler flap.
  • a first actuation of the handle provided in the interior of the motor vehicle body ensures that the locking mechanism assumes its pre-latching position. In the pre-locking position, the hood or front hood is still secured.
  • the pre-load position corresponds to the fact that the locking mechanism has been opened slightly or that the rotary latch has carried out a slight opening movement.
  • the hood or front hood is accordingly set up opposite the motor vehicle body and defines a gap.
  • the pre-latching position consequently corresponds to the fact that the sealing pressure of a circumferential seal that seals the front hood in the example with respect to the motor vehicle body is reduced.
  • the hood or front hood can be unlocked by actuating the handle a second time and then opened without any problems. Since the first and second actuation of the handle are carried out from inside the motor vehicle body, the hood or front hood can consequently be opened completely by internal actuation. This is particularly convenient compared to the hook locks used in practice up to now.
  • the storage position corresponds to the pre-latching position of the locking mechanism or the rotary latch. Since the pawl previously in the storage position and lifted from the rotary latch has been transferred to its releasing release position during the previous opening process of the hood, the pawl can be moved into the supply position or without force during the described closing process of the hood in the lock-holder bracket Storage position pivoted rotary latch fall. A situation such that the hood or front hood is put down without the locking mechanism engaging and holding and securing the lock retainer bracket at least in the pre-locked position is consequently not possible.
  • the locking mechanism After the first actuation of the handle inside the motor vehicle body, the locking mechanism is moved into the pre-latching position. In the pre-latching position, the lock retainer bracket still falls into the rotary latch. The hood is relieved and can be opened slightly by defining the previously mentioned gap between the motor vehicle body and the hood. This is ensured by at least one spring acting on the hood or the rotary latch.
  • the force of the spring is now such that the lock retainer bracket still falls into the rotary latch even in the storage position.
  • the storage position is reached or assumed in that the hood is unlocked.
  • the handle provided in the interior of the motor vehicle body is actuated a second time.
  • the unlocked hood is now to be opened, an operator can easily grasp the hood through the gap and swing it open.
  • the catch is pivoted into its open position. Since the pawl is held in the storage position raised from the rotary latch with the aid of the storage element, the rotary latch can pivot freely and immediately releases the lock retainer. The same goes for the hood.
  • the lock retainer bracket which has fallen into the rotary latch in the storage position, ensures that the pawl is transferred into the releasing release position. That is, the lock retainer bracket that has fallen into the rotary latch controls the pawl in such a way that it relinquishes its lifted storage position and is transferred to the releasing release position. Since during the first opening process in question, the rotary latch is pivoted from the pre-latched position into the open position with the aid of the lock-holder bracket that is acted upon in the opening direction, the pawl transferred into the release position can no longer interact with the rotary latch, but lies on the outside of it without the possibility of interaction.
  • the lock retainer bracket falls without force at least into the rotary latch which can be pivoted into the pre-latching position.
  • this pre-latching position corresponds to the position in which the hood or front hood is held, as it were, suspended in relation to the motor vehicle body.
  • the lock retainer bracket pivots the rotary latch at least into the pre-locking position. Since the pawl is in the releasing release position, it can at least snap into the preliminary catch on the rotary latch. This will secure the lock retainer bracket and with it the hood. Unintentional swiveling open of the hood or front hood is not possible even during subsequent driving.
  • the rotary latch or the locking mechanism and consequently the hood lifted off from the motor vehicle body can also be queried with the aid of a sensor or switch. Its signal can be output visually and / acoustically inside the motor vehicle as a warning for the vehicle driver. Such a warning signal can at least be emitted when the motor vehicle is to be started in this pre-locked position of the locking mechanism. This is where the essential advantages of the invention can be seen.
  • the motor vehicle door lock has a switching lever designed as a two-arm lever with a stop arm resting on the lock holder bracket and a bearing arm carrying the storage element, on which the storage element is mounted, the storage element being designed as a storage lever with a blocking arm interacting with the pawl and a control arm interacting with the switching lever.
  • the shift lever for its part mostly protrudes into an inlet mouth of the locking mechanism and rests against the lock holder bracket (continuously).
  • a spring that prestresses the shift lever in the direction of its contact on the lock holder bracket may provide for this.
  • the storage lever is generally biased towards the storage position with the aid of a spring. After the pawl is lifted from the rotary latch during the unlocking process, starting from the pre-latching position of the locking mechanism, the storage element moves with its blocking arm supported by the spring against the pawl. This holds the pawl in this storage position.
  • the pawl is equipped with a stop pin.
  • the stop pin on the pawl ensures that the storage element or the storage lever cannot pivot into the storage position in the pre-latching position of the locking mechanism following the first actuation of the handle inside the motor vehicle body.
  • the stop pin of the pawl in question interacts with a side surface of the blocking arm of the storage element in question.
  • the stop pin on the pawl moves along the side surface of the blocking arm of the storage element. At the end of this movement, the storage element is pivoted into the storage position with the aid of the spring.
  • the stop pin of the pawl rests on a front surface of the blocking arm.
  • the storage element now in the storage position ensures that the pawl is held in this raised position with respect to the rotary latch. This is ensured by the stop pin on the front surface of the blocking arm.
  • the blocking arm of the storage element is therefore advantageously in the storage position on the described stop pin of the pawl.
  • the lock holder bracket As soon as the hood is opened starting from this storage position, the lock holder bracket, which is still in the storage position in the rotary latch, ensures that the pawl is transferred into its released release position. To this end, the lock holder bracket not only swivels the rotary latch from the pre-latching position into the open position, but the switching lever, which is spring-supported on the lock holder bracket, follows the opening movement of the lock holder bracket.
  • the storage lever or storage element mounted thereon is also pivoted together with the switching lever which is pivoted at the same time as the lock holder bracket moved in the opening direction.
  • This pivoting movement of the storage element together with the shift lever has the consequence that the front surface of the blocking arm of the storage element moves away from the stop pin of the pawl.
  • the pawl is brought into its released release position with the assistance of a spring.
  • a motor vehicle door lock and in particular a motor vehicle front hood lock, is made available which brings considerable security advantages and at the same time is of simple construction. Because next to The locking mechanism only requires the gear lever and the storage lever mounted on it. Additional drives are not required. This also increases the functional reliability.

  • the lock retainer bracket 3 can now collapse into the locking mechanism 1, 2 without force. Because the hood 4 is in the pre-locking position after Figure 2A and 2 B in a quasi-floating or force-free state with respect to the motor vehicle body. Even when moving from the stock position to the Figure 2A and 2 B towards the storage position according to the Figure 3A and 3B the rotary latch 1 is not pivoted any further. As a result, the lock holder bracket 3 still falls into the rotary latch 1 in the storage position.
  • a closing process of the hood 4 corresponds in any case to the fact that the lock holder bracket 3 without force moves the rotary latch 1 into the pre-latching position as shown in FIG Figure 2A and 2 B pivoted. Since the pawl 2 has previously been transferred to its releasing release position and consequently its basic position after the Figure 1A and 2A assumes, the pawl 2 can fall directly into the first catch 15 of the rotary latch 1. This applies even if the hood 4 is put down very slowly by an operator and is not subjected to an additional force.
  • the lock retainer bracket 3 only ensures that the rotary latch 1 is in the Figure 3A indicated open position is transferred into at least the position associated with the pre-latching position. Since the pawl 2 can collapse immediately in the pre-locked position, the lock retainer bracket 3 is secured in any case. At the same time, the microswitch or sensor 13 actuated in the pre-latching position ensures that that the warning signal already described above is emitted or undergoes a corresponding evaluation.
