Definitions

  • the invention relates to opening and / or closing mechanism on doors, flaps or the like.
  • a motor vehicle with a lock having a housing in which at least one locking element is arranged, which has a pawl and a catch and a closing element designed as a closing element which is in operative engagement with the lock in the closed position, wherein the rotary latch between a release position and the locking element catching locking position is displaced, and the rotary latch has at least one rotary latch section with at least one stop surface and the pawl has at least one pawl portion with at least one stop surface, wherein in Locking position, the stop surface of the rotary latch portion and the abutment surface of the pawl portion in a contact area touch, and that the housing at a deformation of the housing at least partially by the blocking element, in particular From a portion of the catch, is contacted to prevent the door from opening.
  • Locks are known from the prior art, which have a catch and a pawl. At high loads transverse to the opening direction of the catch and the pawl disengage, so that the lock could open prematurely in an impact.
  • a vehicle door lock which has a rotary latch and a pawl.
  • the rotary latch has a latching nose on which forms a positive connection with a deformation of the housing with a side wall of the housing to prevent opening of the door.
  • a disadvantage of this solution is that the catch additionally must be provided with a detent which has only the function to form a positive connection with a deformation of the housing, for example in a crash with the recess on the housing. This means a higher production cost, which unnecessarily increases the manufacturing cost.
  • a vehicle door lock which has a rotary latch and a pawl.
  • the catch on two locking lugs which are aligned perpendicularly in the direction of the housing to form a positive connection in a crash with the recesses of the housing.
  • the housing is not deformed, but the rotary latch is tilted due to a desired bending point B on the holding element which supports the rotary latch.
  • This solution has the disadvantage that the holding element must have a desired bending point. This in turn is associated with a higher production cost, which increases the construction costs.
  • the state of the art also includes the US6010164A which discloses a vehicle door lock.
  • the housing has a projection, which in turn in a deformation of the housing with a on the Rotary latch arranged projection forms a positive connection to prevent the door from opening.
  • an increased design effort is also necessary in this vehicle lock, since the catch and the housing must be additionally formed with a projection.
  • the object of the invention is therefore to provide a device of the type mentioned above, which ensures even in a crash, especially in a crash that the doors and flaps of the vehicle remain closed and is simple and inexpensive to manufacture.
  • the invention is achieved in that at a deformation of the housing in the blocking position at least one stop surface of a rotary latch portion of the rotary latch connects positively to the housing.
  • the solution according to the invention has the advantage that, in contrast to the prior art, the abutment surface of the rotary latch portion of the rotary latch, which contacts the abutment surface of the pawl portion of the pawl in a contact area in blocking position, at the same time has the function with the housing in a deformation of the housing a positive connection to build. Therefore, can be advantageously dispensed with an additionally arranged on the catch component, such as a latch.
  • the abutment surface of the rotary latch portion of the rotary latch accordingly has two functions. In conventional operation, ie in the locked state, it serves in operative connection with the abutment surface of the pawl portion of the pawl to hold the door in a locked state.
  • the rotary latch has at least one further rotary latch section with a second abutment surface which, when the housing deforms, positively connects to the housing.
  • the housing is associated with at least one means with which at least one stop surface of a rotary latch section connects positively.
  • the means is formed as a recess in the housing, with which at least one stop surface of a rotary latch portion connects positively. This ensures that in a crash, the positive connection between the housing and the abutment surface of the rotary latch portion of the rotary latch remains and opening the door is impossible.
  • the recess on the housing is simple and inexpensive to manufacture.
  • the means is formed as a projection in the housing, with which at least one stop surface of a rotary latch section connects positively.
  • the means is formed as a recess in the housing, with which at least one stop surface of a rotary latch section connects positively.
  • the recess has the advantage that it can be easily integrated into a housing of the lock already known from the prior art. This is preferably done by drilling or punching.
  • the recess lies in a plane which is parallel to a plane in which the side walls of the rotary latch lie. This ensures that the impact forces generated in a crash, which act substantially perpendicular to the side walls of the rotary latch, the abutment surface of the rotary latch portion of the rotary latch leads into the recess on the housing, so that a positive connection between stop surface and recess forms, which opens the Door prevented.
  • the means arranged in the housing is arranged on a first path, which is traversed during the opening / closing operation of at least one rotary latch portion comprising at least one stop surface. If the means, such as the recess mentioned above, is arranged on the first track, then it is ensured that the abutment surface of the rotary latch section of the rotary latch forms a positive connection in the case of a deformation of the housing with the recess.
  • On the track also several means may be arranged, which are arranged at predetermined distances from each other.
  • a plurality of recesses may be arranged on a path which, depending on the deformation of the housing and the position of the rotary latch, can be available for positive engagement with at least one abutment surface of a rotary latch section.
  • Very safe and simple is the structural design of the castle when the housing associated with the means on the first path opposite the contact area is arranged.
  • the means arranged in the housing is arranged on a second path, which is offset in the vicinity of the first path, which is traversed by at least one rotary latch section comprising at least one stop surface during the opening / closing operation.
  • the means associated with the housing is then arranged on the second track, which is arranged substantially opposite the contact area.
  • the means is arranged on a rear side of a rear plate of the housing.
  • abutment surface of a rotary latch section is designed as a projection which connects in a form-fitting manner to the means associated with the housing
  • the lock is located below a door inner panel of a vehicle, in particular on a vehicle door.
  • FIGS. 1 to 3 is designed as an opening and closing mechanism tailgate lock 1 for a tailgate of a motor vehicle, not shown, which is arranged below a door inner panel of a vehicle, in particular on a vehicle door.
  • a closing bracket closing element which is U-shaped and is firmly connected to the vehicle, is in a closed position with the Tailgate lock 1 in operative connection and thus prevents opening of the tailgate.
  • the tailgate lock 1 has a housing 2. Within the housing locking elements are arranged, which are designed as a rotary latch 3 and pawl 4, wherein the rotary latch 3 is displaceable between a release position and a locking element catching the locking position.
  • the rotary latch 3 has a first rotary latch section 5 with a first stop surface 6 designed as a main catch, and the pawl 4 has a pawl section 7 with a stop surface 8.
  • the rotary latch 3 is connected via a pin 9 and the pawl 4 is rotatably supported via a respective bolt 10, which is rotatably mounted respectively on a rear side 11 of the housing 2 via a spring not shown in detail.
  • the first stop surface 6 of the catch 3 and the abutment surface 8 of the pawl is each in the form of a tooth, wherein in the locked position of the tailgate lock 1, the first stop surface 6 of the first rotary latch portion 5 of the rotary latch 3 and the abutment surface 8 of the pawl portion 7 of the pawl 4 in touch a contact area 12.

  • the pre-restraint is provided as a safety means to keep the door in the closed position in the event of a failure of the main rest position, in particular while driving.
  • a failure of the main detent lock position can occur, for example, after the closing operation, the first stop surface 6 of the first rotary latch portion 5 of the rotary latch 3 and the abutment surface 8 of the pawl portion 7 of the pawl 4 touch only tangentially in the contact area 12 and form a frictional connection, because already low on the tailgate lock 1 acting forces, which are caused when driving a motor vehicle, can solve this connection.
  • this compound designed as a stop surface 14 of the rotary latch portion 13 pre-catch serves as a security element that prevents opening of the tailgate.
  • the rotary latch 3 has a further, third rotary latch section 15 with a third stop surface 16.
  • a fixed to the back 11 stop 17 is arranged on the inner rear side of the housing 2.
  • the stop 17 and the third stop surface 16 of the third rotary latch portion 15 are in a non-contact state.
  • the rotary latch 3 rotates back in the direction of arrow A and the third stop surface 16 of the third rotary latch section 15 of the rotary latch 3 abuts against the stop 17. Consequently, the striker and the rotary latch 3 are out of contact and opening of the door flap designed as a door is possible.
  • the stop 17 thus serves as a limitation for a spin of the rotary latch 3.
  • the housing 2 of the tailgate lock can be deformed due to the influence of shear forces.
  • at least one abutment surface 6, 14 of a rotary latch section 5, 13 of the rotary latch will positively connect to the housing 2.
