Definitions

  • the invention relates to a door lock, which in the preamble of claim 1 specified type.
  • the rotary latch takes in its one rotary end position, namely its Rest position, a closing member, which engages there in a main rest and the Latch locked against its spring load. To close the catch in its open position transfer, the pawl is unlocked. Use to unlock the latch a motor-driven working member.
  • the motor is activated if - in the case of user access authorization - e.g. one to the door lock belonging handle is actuated directly or indirectly.
  • a load Energy storage the arm of a storage member, which is attached to the motor driven working member and thus defines the state of charge of the energy accumulator.
  • This storage member has a shoulder, which is used to lift the pawl a counter shoulder on one arm of the jack pushes to the jack by unloading the lift mechanism from its latching position in the catch. This applies to both in the normal case as well as in a special case, if that with a door lock equipped vehicle has experienced a crash.
  • the storage element has a control surface on which the motor-driven working member is supported.
  • the pawl has a long arm, in the end of which a counter control surface is provided against which the working member when lifting the pawl from the Rotary trap in a second, which is staggered in time compared to the first motor drive phase Phase moves.
  • the invention has for its object a door lock in the preamble of Claim 1 to develop the type mentioned the disadvantages avoids. This is according to the invention by the characterizing part of claim 1 specified measures achieved, which have the following special meaning.
  • both the control surface and the counter control surface are on Storage lever provided. Therefore, the arm on the pawl, which is when unloading the lift mechanism should absorb the released lifting force for the pawl, be very short.
  • the center of gravity of the jack is thus very close to hers Pivot point.
  • the additional required after a crash of the vehicle Motor lifting energy for the pawl is also transferred from the working member to the Transfer memory element.
  • the one after the other in the two motor drive phases Amounts of energy applied after a crash over the same places transferred, namely always from the shoulder of the storage member to the counter shoulder the jack. These points can also be very close to the pivot point of the jack.
  • the at the Latch-acting return spring can be designed weaker, what a enables easy opening.
  • the door lock further comprises a link 22, which in the direction of arrow 25 of an energy accumulator 30 is loaded and should therefore be called a "storage element".
  • This storage element 22 could be a slide.
  • This link 22 should always follow “Storage levers” are called, but it goes without saying that an im other sense movable member could be acted upon by the energy accumulator 30.
  • the storage lever 22 strives according to the spring force 25 in one of FIG. 2 or 3 visible swivel position. In the starting position of Fig. 1, the storage lever 22 is prevented from doing so because it is there with one provided control surface 23 on a working member 47, which e.g. of an electric motor 40 is driven.
  • the working member is designed as a cam, which has a special contour profile 45 has and is arranged at a distance from an axis of rotation 46 about which it passes through a motor 40 and a gear can be rotated in the direction of arrow 27.
  • This cam 47 holds the storage lever 22 in the starting position of FIG. 1 in a rotational position ensuring the full state of charge of the energy store 30.
  • the Auxiliary line 22.1 of Fig. 1 indicates the resulting rotational position, the results from the effective profile point 31 on the cam contour 45.
  • This Profile point 31 should be the maximum radial distance from cam rotation axis 46 have. In the rest position of Fig. 1, the door is closed.
  • the storage lever 22 has a shoulder 32 which has a counter shoulder 33 is assigned to an actuating arm 26 belonging to the pawl 20.
  • the when unloading the Force accumulator 30 released spring force 25 also presses the storage lever 22 his shoulder 32 against the counter shoulder 33 on the pawl 20 and lifts it the main catch 17 of the rotary latch 11. Then the catch 11 under the Effect of the restoring force 12 acting on them up to one from FIG. 2 apparent open position to be released.
  • the catch 11 has emerged from there dash-dot indicated rest position in the drawn open position pivoted the angle 19.
  • the locking part is from the receptacle 14 of the catch 11 extended and in its drawn release position 10 'of FIG. 2nd arrives.
  • the mentioned counter shoulder 33 on the pawl 20 can be used be reinforced from harder material.
  • the storage lever 22 also has a counter control surface 29. This comes about because the control lever 22 in its end region 34 is provided with an opening 35 which is divided into two legs 36, 37 creates. Although it is not necessary, here are the two leg ends connected by a web 38, whereby the cutout 35 here Looks like an "eyelet".
  • the eyelet 35 has an elongated, kidney-shaped profile. The edges of the eyelet 35 directed towards each other in the direction of rotation 27 form the edges the control or counter-control surfaces 23, 29 interacting with the cam 47.
  • Fig. 2 shows the normal case where the rotation 27 of the control cam 47 already ends before the control cam has reached the counter control surface 29. Then stops the motor rotates in the direction of rotation 27.
  • the excavated is supported Locking arm 21 of the pawl 20 on a designated contact surface of the catch 11 from; the pawl 20 is held in a standby position.
  • the cam 47 comes with a second profile point 39 in another area of the control surface 23 for support.
  • the auxiliary line 22.2 indicates the same mark as in Fig. 1 shows the open position of the trap 11.
  • the cam 47 has in this normal case 1 moved in the direction of rotation 27 by an angular range 41. This Movement has only come about by unloading the energy accumulator 30.
  • the cam 47 has the control surface 23 leave and take the intermediate rotary position indicated by the auxiliary line 22.4 on. 4, the cam 47 has the one shown in FIG. 2 and 41 designated angle is not yet completely completed, but only the one with 43 go through marked partial angles. Thereby, the im Energy storage 80 charged energy, but, as I said, in the event of a crash it is sufficient for Do not lift out the pawl 20.
  • the cam 47 could in the interior of the eyelet 35 in the same direction 27 continue to the initial situation of Fig. 1, but in this Embodiment, the engine 40 via the control logic mentioned stopped what again by means of the sensors, e.g. at 51, 52. Then changes the motor 40 has its direction of rotation in the direction of the counter-rotation arrow 48 counter-current the motor 40. The cam 47 bumps during this reverse rotation 48 to the control surface 23 and moves the storage lever 22 back into the starting position shown in FIG. 1 back.
  • the one in both Motor drive phases at 41 on the one hand and at 50 on the other hand in succession In the event of a fault, the applied forces are applied via the same points of contact, namely the shoulder 32 and the counter shoulder 33 between the two components 20, 22 transmitted.
  • the storage lever 22 serves as an opening aid for lifting the Jack both in the normal case and in the event of a fault.
  • the outline 45 of the control cam is drop-shaped, its profile on the with respect to the cam rotation axis 46 radially outer side asymmetrical the opposite cam inside can be formed.
  • the Corresponding edge profiles on the surfaces 23, 29 are counter-profiled for this purpose. Because the pawl 20 only has a short actuating arm 26, which is not the large one Counter-control surface 29 needs to bear, its focus is very close to his Pivot 15. Inertial forces that result in a crash are therefore low. Unwanted automatic lifting of the pawl 20 cannot occur come more. This easily increases security to over 30 times Acceleration of gravity reached.
