Definitions

  • the invention relates to a motor vehicle lock with a latch and a pawl arrangement according to claim 1.
  • the motor vehicle lock in question finds application in all types of closure elements of a motor vehicle. These include, for example, side doors, in particular sliding doors, tailgates, trunk lids, engine hoods, load compartment floors or the like of a motor vehicle.
  • the pawl assembly of the motor vehicle lock is equipped with two pawls, namely with a pivotable primary pawl and with a pivotable secondary pawl.
  • the primary pawl serves to lock the latch in its respective closed position, in particular in its main closed position or prelocking position, against pivoting in its opening direction.
  • the secondary pawl acts to lock the primary pawl in its incidence position against pivoting in its lift-off direction, so that the latch, which cooperates with a closure member, such as a striker or the like, securely in its main closed position is held.
  • the invention is based on the problem of specifying a motor vehicle lock with a pawl arrangement of at least two pawls, in which an improved containment and driving acoustics is achieved with little design effort.
  • the latch is pivotable in at least one closed position, in particular in a main closed position and possibly in a pre-closed position.
  • the latch located in a closed position above is in the mounted motor vehicle lock with a closing part in holding engagement, which may be a striker, a locking pin or the like.
  • the pawl assembly has a primary pawl which is pivotable in a direction of incidence about a geometric pivot axis in an incident position in which it locks the latch in a closed position against pivoting in its opening direction, and in a Aushebecardi about the geometric pivot axis in a Aushebewolf is pivotable, in which it releases the latch in its opening direction.
  • the primary pawl is therefore in locking in the main closed position and in the possibly present prelocking latch in locking engagement with the latch.
  • the primary pawl is biased in the direction of its incidence position.
  • locking engagement is to be understood widely in the present case and includes any engagement by means of which the latch can be held in the respective closed position.
  • a latching, self-holding intervention is thus not necessarily meant, as will become apparent from the following explanations.
  • the pawl assembly includes a secondary pawl pivotable in a direction of incidence about a geometric pivot axis to an incidence position in which it locates the primary pawl in its incidence position against pivoting in its lifting direction locks, and which is pivotable in a Ausheberaum about the geometric pivot axis in a Aushebewolf in which it releases the primary pawl in its Ausheberaum.
  • the secondary pawl thus ensures that the primary pawl located in their Einfall ein can not be excavated.
  • the secondary pawl is biased in the direction of its incidence position.
  • a boundary surface of the primary pawl and a boundary surface of the secondary pawl are in holding engagement with each other or can be brought into holding engagement that a Einfalltiefenbegrenzung the primary pawl is provided in its direction of incidence.
  • the depth of incidence of the primary pawl is thus limited by the holding engagement, which can also be a engaging engagement.
  • the primary pawl so when reaching the predetermined depth of incidence no longer follows the outer contour of the latch when it pivots further from the main closing position in an overstroke position, as at the predetermined depth of incidence of the primary pawl engagement between the boundary surfaces of the primary pawl and the secondary pawl further movement of the primary pawl in prevented their direction of incidence.
  • a noise that results from vibrations or rattling of the secondary pawl prevent or at least minimize.
  • This is for example an advantage on poor roads, but also leads to a corresponding noise reduction when closing a closure element, which is equipped with a corresponding motor vehicle lock.
  • Another advantage is that the primary pawl can not easily jam due to too deep incidence, which can safely open the motor vehicle lock and thus the closure element.
  • the tolerance chain is reduced within the motor vehicle lock, since the primary pawl has a defined stop on the secondary pawl, which determines the depth of incidence.
  • Claims 2 to 5 define preferred courses of the boundary surfaces of the primary pawl and the secondary pawl.
  • the boundary surface of the primary pawl and / or the boundary surface of the secondary pawl at least partially, in particular at least for the most part, preferably completely, on a straight line passing through the geometric pivot axis of the primary pawl (claim 3 ).
  • the straight line runs in particular orthogonal to the geometric pivot axis of the primary pawl.
  • the respective boundary surface extends at an angle of 0 ° to 45 °, preferably from 0 ° to 20 °, particularly preferably from 0 ° to 10 ° to a straight line which, in particular orthogonal, through the geometric pivot axis the primary pawl runs.
  • the respective boundary surface orthogonal to a straight line extending through the geometric pivot axis of the secondary pawl extends (claim 5). This straight line runs in particular orthogonal to the geometric pivot axis of the secondary pawl.
  • the respective boundary surface extends at an angle of 45 ° to 90 °, preferably from 70 ° to 90 °, particularly preferably from 80 ° to 90 °, to a straight line which, in particular orthogonal, by the geometric Pivot axis of the secondary pawl runs.
  • the angle here always means the smaller angle between two straight lines, ie the acute angle.
  • the two boundary surfaces of the primary pawl and secondary pawl extend in the state of retaining engagement of the two boundary surfaces at least in sections, in particular at least for the most part, preferably completely, parallel to each other.
  • the two boundary surfaces advantageously at least partially contact each other flat, punctiform and / or linear (on a line).
  • At least one of the two boundary surfaces is bent at least in sections, wherein both boundary surfaces may be bent at least in sections.
  • these are punctiform or linear, ie not flat, against one another.
  • the claims 8 to 10 define a limiting portion of the primary pawl and a limiting portion of the secondary pawl on which the respective boundary surface is formed.
  • the respective limiting section can in this case protrude relative to the respective pawl, moreover, in particular with respect to a lever arm of the pawl, that is to say protrude relative to the course of the outer contour of the respective pawl in respectively adjacent sections.
  • the respective limiting portion is substantially hook-shaped (claim 10). In this way, the one boundary section with its associated boundary surface engage behind the respective other boundary section with its associated boundary surface and thus limit the depth of incidence.
  • the respective limiting section or the respective pawl can also have a stop surface, wherein the stop surfaces cooperate with each other in such a way that they come into abutment in the state of the retaining engagement of the two boundary surfaces and thereby limit a movement of the secondary pawl in its direction of incidence (Claim 11).
  • the abutment surfaces thus define an end position of the pivoting movement of the secondary pawl in the direction of incidence, in which the primary pawl and the secondary pawl are in said holding engagement or can be brought into said holding engagement.
  • the Einfalltiefenbegrenzung can be formed so that the incidence position of the primary pawl when the latch is in its main closed position, identical or at least substantially identical to the incident position of the primary pawl when the latch is in an overstroke position and the state of holding engagement of the two boundary surfaces is set with each other.
  • the incidence position of the primary pawl does not change, or at least not significantly, when the latch is brought from its main closed position into an overstroke position.
  • the depth of incidence limit but can also be designed so that the primary pawl from its incident position when the latch is in its main closed position moves a defined way further in their direction of incidence, when the latch is brought into an overstroke position.
  • the primary pawl is so in the state of the holding engagement of the two boundary surfaces collapsed with each other further than in the state in which the latch is in its main closed position.
  • the boundary surfaces when the lock latch is in its main closed position, a game between each other or are free of play on each other.
