Definitions

  • the invention is directed to a closure of the type specified in the preamble of claim 1.
  • the lock associated with the lock comprises a latch, a latch with an actuator arm and a motorized opening aid.
  • the opening aid has a driven eccentric whose eccentric cam cooperates with a lateral footprint on the actuator arm to move the pawl by motor from its locked position in the case in an Aushebelage. Then the trap is free to release the captured by her closing part.
  • the DE 102 06 813 A1 shows a known closure of this type, where the eccentric is formed dimensionally stable over the entire length of its eccentric curve. If the release position of the pawl is present and the case is released, it may come due to the load to a movement in the reverse direction of the eccentric, where an end segment of the eccentric, which has the maximum radii relative to the eccentric axis, moves back in front of the actuating arm of the pawl. Then the pawl is fixed in its Aushebelage and can not come again in the latching position of the latch with the case. The closure can then not be brought into its closed position, he is not able to hold the detected lock in the lock.
  • the invention has for its object to develop a reliable inexpensive closure specified in the preamble of claim 1 way that excludes malfunction of the castle. This is inventively achieved by the features specified in the characterizing part of claim 1, which has the following special significance.
  • the peculiarity of the invention is to form an end segment of the eccentric, where the eccentric cam has the maximum radii relative to the eccentric axis, in the radial direction elastically yielding.
  • the actuating arm of the pawl in the radial direction could be elastically yielding.
  • the latch In full Aushebelage the latch then it comes to an elastic snap, because the latch is then supported on a fixed stop in the lock and can not be pivoted further.
  • an eccentric shoulder which limits the maximum end radius of the end segment, snaps behind a counter-shoulder on the actuating arm.
  • the radial distance between the pawl actuating arm and the eccentric axis is significantly smaller than the maximum end radius of the eccentric cam.
  • a space-consuming relay for short-circuiting the motor contacts after switching off the current is not required in the invention.
  • This component can be saved in principle in the invention.
  • the aforementioned excess of the radius of the end segment prevents the above-mentioned malfunction of the lock according to the invention. Without relay it may indeed come after the stop of the engine in the invention to a reverse rotation of the eccentric, but this reverse rotation is certainly limited by a support of the eccentric shoulder with the pawl counter-shoulder. An uncontrolled reverse rotation of the eccentric is then reliably prevented.
  • the lock according to the invention consists of a lock with a lock housing 12 and a closing part 10.
  • the lock housing 12 is attached to a movable tailgate 50 of a vehicle, of which in Fig. 1 only a portion is shown.
  • the closing part 10 consists of a striker, whose two legs are seated on a stationary body 60 of the vehicle, from which in Fig. 1 dot-dashed only a portion is illustrated.
  • the one leg 11 of the striker 10 is in engagement with one of the lock components, namely a case 15th
  • the case 15 has a slot-shaped receptacle 13 for the front leg 11 of the striker 10.
  • a pawl 20 is mounted on a pivot axis 26 in the housing 12, which is under the action of a spring load 29 illustrated by the force arrow 29. What the latch 20 looks like is especially good Fig. 6 and 8th refer to.
  • the pawl 21 has three arms 21, 24 and 28, which not only have different arm lengths and extend in different directions with respect to the pivot axis 26, but also in three mutually different altitudes 51, 54, 58 are located in Fig. 6 dash-dotted lines are illustrated. The different height of these arms 21, 24, 28 is highlighted in the drawings by different hatching.
  • the three arms have three different functions to be described, which are already expressed in their designation.
  • the first arm 21 is a "control arm 21" located in the top 51 of FIG Fig. 6 is arranged.
  • a second, lying in a middle plane 54 arm 24 is a "blocking arm”.
  • the third arm 28, which is arranged in the lowest level 58, should be referred to as a "support arm”.
  • the pawl 20 still has two lugs 27, 57, of which the first 27 is a "locking lug", because they are in the Fig. 1 apparent locking position of the lock components, the main catch 17 of the latch 15 engages behind.
  • the other nose 57 relies in the locking position of Fig. 1 on the peripheral contour of the latch 15, which lies between the main catch 17 and the pre-catch 16.
  • the second nose 57 should be referred to as a "support nose”.
  • the support lug 57 determines the depth of engagement of the locking lug 27 on the main catch 17th
  • Another component of the lock is arranged in the lock housing 12 motor opening aid 30.
  • This consists of a switchable by an electrical control unit and motor 31, one out Fig. 1 recognizable screw 32 and a worm wheel 33 engaged therewith.
  • a segment-like eccentric 40 is rotatably connected via an eccentric axis 44.
  • the eccentric is formed according to the invention in a special way, which is best based on the magnification in Fig. 7 can be explained.
  • the eccentric 40 has an eccentric cam 46, which begins with respect to the eccentric axis 44 with a smallest radius 61 and extends over a mean radius 62 up to a maximum end radius 63.
  • the eccentric cam 46 can be subdivided into two segments 41, 42, namely a main segment 41 and an end segment 42 designed according to the invention.
  • the eccentric disk 40 Apart from the reinforced edge flange 36 for the eccentric cam 46 and radial ribs, the eccentric disk 40 consists of a disk 47, which is provided in the region of the end segment 42 with a slot 38 which weakens the disc in this end segment 42. It remains at the reinforced edge portion 36 of the eccentric 40 only a small slice remnant 39, which, however, widens again to the free end face 49 and there generates a relatively wide eccentric 43.
  • the eccentric 40 is integrally formed and made of plastic material. Due to the slit weakening of the disc remainder 39 is radially flexible.
  • FIG Fig. 7 illustrated radial deformation.
  • the maximum radius 63 may be as shown by a dashed line 56 in FIG Fig. 7 temporarily reduced to the middle radius 62 at times.
  • the end segment 42 acts as a "spring arm" of the eccentric 40, the in Fig. 7 labeled 48.
  • the Fig. 1 shows a Zuklapplage the tailgate 50, to which the lock housing 12 is attached. Then, the rotary latch 15 is in engagement with the one leg 11 from the closing part 10 and is supported with its main catch 17 on the locking lug 27 of the pawl 20 from. Then the illustrated by the auxiliary line 15.1 main latching position 15.1 of the case 15 is present while the pawl is in its illustrated by the auxiliary line 20.1 locking position 20.1.
  • the motor 31 is initially at rest, whereby the eccentric 40 occupies the marked with the auxiliary line 40.1 starting position.
  • the closure is, as already said, in its locked position.
  • the unlocking of the closure is normally carried out by motor means of the opening aid 30.
  • the authorized person expresses the desire to open the tailgate 50, in a manner known per se to an electrical control unit, not shown in detail, which then activates the engine 31 puts.
  • the eccentric 40 is set in motion via the gear 32, 33 and thereby passes into one Fig. 2 apparent first intermediate position 40.2.
  • the main segment 41 moves from the eccentric 40 against a footprint 22 from the actuating arm 21 and thereby pushes the pawl 20 in a marked with the auxiliary line 20.2 initial phase, where the locking lug 27 of the pawl 20 has not only released the main catch 17, but also the Vorrast 16th the trap 15.
  • the switched-on motor 31 initially runs up to the in Fig. 3 with 40.3 marked second intermediate position of the eccentric 40 on.
  • the resilient eccentric end segment 42 cooperates with the footprint 22 of the pawl actuating arm 21. It comes to the already in Fig. 7 explained deflection 56 of the spring arm 48 formed by the end segment 42. The extent of the bending is by the already in Fig. 7 explained and also in Fig. 3 drawn arrow 59 can be seen.
  • Fig. 3 shows the pawl 20 in its illustrated by the auxiliary line 20.3 full lifting position.
  • the closing part 10 is released and is therefore in the marked by the auxiliary line 15.3 full open position.
  • the engine 31 continues to run until the off Fig. 4 revealed conditions.
  • Fig. 4 beats the eccentric 40 with its front abutment surface 45 at a blocking arm 24 located on the block 20 of the pawl 20 at. Thereby, the movement of the components of the opening aid 30 is stopped. A space-consuming, expensive relay for shorting the motor 31 is eliminated.
  • the stop of the motor 31 is registered by the electric control unit, for example, by a steep rise of the electric current and the power supply to the motor 31 is turned off.
  • the eccentric 40 is located in Fig. 4 in an overstroke position, where also the end of the spring arm 48, the footprint 22 has not only released from the eccentric actuator arm 21, but is at a distance 53 thereto.
  • the footprint 22 has not only released from the eccentric actuator arm 21, but is at a distance 53 thereto.
  • Fig. 4 another gap 53.
  • the trap 15 is still in its already off Fig. 3 recognizable disclosure.
  • the closing part 10 has moved farther away from the trap receptacle 13.
  • the in Fig. 1 fragmented, but in the Fig. 2 to 8 have been omitted, is in the overstroke position of Fig. 4 already a gap, which then opens further.
  • Fig. 7 show the abutment surface 45 at the beginning of the dimensionally stable main segment 41 of the eccentric 40.
  • This abutment surface 45 extends approximately vertically to the eccentric 46 at this point.
  • the associated counter-impact surface 25 of the pawl blocking arm 24 is located at the free end of the front.
  • the auxiliary line 20.4 marks in Fig. 5 Due to the aforementioned conditioning of the pawl locking lug 27 on the circumference of the case 15, the pawl 20 is ready for a future Zuklappterrorism the tailgate ready to reliably fall into the pre-catch 16 or main catch 17 of the case 15. This closing movement takes place relative to the closing part 10 in the dash-dotted arrow direction 64.
  • This standby position 20.4 of the pawl 20 may additionally or alternatively provide the described butt joint of the eccentric shoulder 43 on the pawl counter-shoulder 23. By means of the locking lug 27, the ready position 20.4 even in the overstroke position of Fig. 4 available.
