Definitions

  • the invention relates to a lock with a stop device, in particular on the front hood of a motor vehicle, with the features specified in the preamble of claim 1.
  • Such a castle is in the DE 100 33 772 A1 Specifically provided on a motor vehicle front hood and has a stop which limits the rotation angle of a cooperating with a locking pin rotary latch in its locking position in normal operation, in which the catch is held by a sunken in front of a catch of the catch pawl. For example, in a lively closing of the front hood this is braked in the locking position on the cooperating with the locking pin catch and cooperating with the catch stop, whereby the catch can not rotate much beyond their locking position addition.
  • the stop is effective only when the catch is already applied to the stop. The attack must therefore absorb the flywheel energy of the bonnet in a very short period of time, possibly an abrupt noise is transmitted to the body of the motor vehicle.
  • facilities are provided which detect an accident or an imminent accident and, if appropriate, adjust the stop, for example via explosive means from the adjustment of the rotary latch.
  • the rotary latch can rotate beyond the locking position and execute a crash stroke. This can be used as a deformation path to dampen or intercept the accidental impact on any components that are not specified.
  • the invention is based on the object to provide a lock with the features in the preamble of claim 1, which can catch a sweeping closing the lockable door or hood more effective and less disturbing.
  • the pivoting part can be arranged to be pivotable about a stationary or movable real or virtual axis and during pivoting of the lockable door or hood at a predeterminable distance before closing the door or hood through the lock with the locking pin or the stop member in abutment come.
  • the lock shown in Figure 1 according to a first embodiment in the locking position in a side view is arranged in the front side region of an engine hood, not shown, of a motor vehicle.
  • the pivotally supported in the rear area bonnet is arranged approximately horizontally in its pivoted closed position.
  • a further lock for holding the closed hood is provided, which has a lock corresponding to the figure 1 construction.
  • the lock has a rotary latch 1 which cooperate with a locking bolt 2 projecting downwardly from the underside of the hood about a body-fixed axle 3 from the open position shown in FIGS. 2 and 5 into a locking position corresponding to FIGS. 1, 3 and 6 is pivotable.
  • the lock also has a stop device with a pivotable about the axis 4 pivot member 7, which has a cooperating with the locking pin 2 area 8, the flat and formed in the locking position shown in Figure 1 in a direction of movement of the locking pin 2 approximately vertical plane is arranged.
  • the pivoting part 7 forms a lever 9 of a four-bar linkage with two pivotable levers 9, 10, which are each pivotally connected to a lever arm about a hinge axis 11, 12 pivotally connected to a coupling rod 13.
  • the remote from the pivot member 7 lever 10 of the four-bar link is stretched two-armed and pivotally supported about a central, body-mounted pivot axis 21.
  • a simplified illustrated damping cylinder 14 is pivotally mounted at one end about the axis 4.
  • the damping cylinder 14 has an axially adjustable damping piston 15 which is connected to an axially projecting piston rod 16 which at its projecting end about a hinge axis parallel to the axis 4 17 is pivotally attached to the free lever arm of the lever 10.
  • the damping piston 15 separates two working chambers of the damping cylinder 14, which are connected via at least one axial throttle opening 18 with a constant or pressure-dependent variable cross-section in the damping piston 15 or connectable.
  • a spring element 19 is arranged, which loads the piston rod 16 axially outward.
  • a gaseous or liquid damping fluid In the working chambers of the damping cylinder 14 is a gaseous or liquid damping fluid. The two working chambers of the damping cylinder 14 together form a dependent of the axial position of the piston rod 16 working volume, which is compensated by a gaseous, not shown compensating volume.
  • the catch 1 can be adjusted beyond its locking position in the closing direction.
  • An adjustment of the catch 1 in the closing direction beyond its locking position addition is advantageous if an accidental impact occurs on the closed by the locks bonnet, because then the hood can yield in the field of locks.
  • the damping cylinder 14 and the spring element 19 are not or not substantially effective in this case, the accidental yielding of the hood is attenuated and / or cushioned by further, not shown damping elements and / or spring elements.
  • the area (8) of the pivoting part (7) which cooperates with the locking pin (2) or stop part is flat, as shown in FIG.
  • the region cooperating with the locking pin (2) or stop member may be convex or otherwise formed as shown in Figure 10 to the locking pin.
  • the fourth embodiment shown in FIGS. 11 to 14 is similar to the first embodiment shown in FIGS. 1 to 8 formed.
  • the components which are comparable in these exemplary embodiments are provided with a same reference number and for distinction in the fourth exemplary embodiment with a superscript symbol.
  • the pivoting part 7 "' is loaded by a leg spring 25 in the direction of the locking pin 2.
  • the pivoting catch 1, which is pivotable about a body-fixed axle 3, is loaded by an elastic spring, not shown, into its open position shown in FIG.
  • the pivoting part Upon further closing of the door or flap or bonnet, the pivoting part is pivoted against the biasing force of the spring element 19 'in the position shown in Figure 12, in which a laterally from the pivot member 7 "' projecting cam 26 on a leg 27 as a leg spring Approximately in the figure 12 corresponding position of the locking pin 2 also comes to the plant leg 20 of the catch 1 to the system and pivots the catch 1 on further closing in its locking position.
  • the catch 1 Due to the momentum of the door or flap or bonnet, the catch 1 is pivoted about the locking bolt 2 cooperating with it in the locking position shown in Figure 13, in which a spring-loaded pawl, not shown, automatically falls in front of a catch on the catch 1 and thereby a Turning back the rotary latch 1 in the direction of its open position prevented.
  • the damping cylinder 14' is when closing the door or Flap or hood dampens the movement of possibly closed with an oversized swing door or flap or bonnet and / or slows down. Any components located on the door or flap or bonnet, such as headlights on a hood, are not or less shaken by this, which are thus protected by the stopper.
  • the rotary latch 1 in the event of an accidental impact on the door or hood or bonnet closed by the lock, the rotary latch 1 can be moved in the closing direction beyond the locking position shown in FIG. 13 into the overrunning position shown in spring 14.
  • the impact is slowed down and / or damped by spring and damping elements, not shown, and / or via the damping cylinder 14 'and / or the spring element 19' and / or the leg spring 25 and / or the elastic spring acting on the rotary catch 1.
  • the damping cylinder and / or the spring element can be effective in the displacement of the catch in the closing direction beyond your locking position individually or together and directly or indirectly on the pivoting part and / or on the lockable door or flap an impact absorbing and / or slowing down force or a corresponding torque causes.
  • another adjustment kinematics for the pivoting part may be provided.
  • the damping element and / or the spring element can act on any part of the provided for adjusting the pivoting part kinematics.
  • a direct introduction of force and / or torque into the pivoting part can also take place.
  • another stop member may cooperate with the pivot member, which may be, for example, the catch.
  • the arranged on the door or hood locking bolt or the attached stop member may be individually or collectively attached to the door or hood bearing part or on the door or hood. This also applies to the other castle parts.
  • the closable by the lock door or hood can be closed by at least one lock.
