Definitions

  • the invention relates to a motor vehicle door handle arrangement for actuating a motor vehicle door, with a bellcrank which is rotatably mounted about an axis and which, when rotated around the axis, acts directly or indirectly on a motor vehicle door lock in order to release the lock and to enable opening of the motor vehicle door.
  • Such motor vehicle door handle arrangements for operating a motor vehicle door are known.
  • the problem with the known arrangements is that, in the event of an accident, they can inadvertently move from the rest position into the actuating position due to the acting forces and the inertia of individual components, so that in an accident it can happen that the door lock unlocks and the door opens becomes.
  • From the DE 102 60 900 A1 is an outer door handle for a locking device with a housing part fastened to the door and a handle that is articulated in the housing part and is coupled to a pivot arm mounted in the housing part for actuating the lock and with a device for preventing the door from opening in the event of a side impact the door is known, the device for preventing the opening of the door having a scanning device which detects deformation of the door and activates a device which blocks a pivoting movement of the swivel arm.
  • the document US 2011/0095546 A1 comprises a motor vehicle door handle arrangement according to the preamble of claim 1.
  • the object of the invention is therefore to develop a motor vehicle door handle arrangement for actuating a motor vehicle door in such a way that it has improved safety in the event of an accident of the motor vehicle.
  • This object is achieved according to the invention by a motor vehicle door handle arrangement according to claim 1.
  • Advantageous developments of the invention are specified in the subclaims.
  • the motor vehicle door handle arrangement for actuating a motor vehicle door, with a bellcrank which is rotatably mounted about an axis and which, when rotated about the axis, acts directly or indirectly on a motor vehicle door lock in order to release the lock and to enable an opening of the motor vehicle door, it is that the motor vehicle door handle arrangement has an abutment which blocks the bell crank after plastic deformation of the motor vehicle door handle arrangement.
  • blockage of the deflection lever means that the arrangement of the abutment after plastic deformation of the motor vehicle door handle arrangement, for example as a result of an accident in the motor vehicle, prevents the deflection lever from rotating about its axis from the rest position into the actuating position.
  • the abutment is preferably formed by a body part and or a pane, in particular a side pane of a motor vehicle and or a handle housing of the motor vehicle door handle arrangement.
  • the motor vehicle door handle arrangement can thus be designed such that after installation in a motor vehicle door itself it has an abutment, for example through the handle housing of the motor vehicle door handle arrangement, and or is positioned such that in the event of plastic deformation of the motor vehicle door handle arrangement, the abutment is caused by a body part of the motor vehicle in which the Motor vehicle door handle assembly is installed, comes into engagement and acts as a blocking element and blocks the bell crank.
  • the abutment can be formed by a pane, in particular a side pane of the motor vehicle, in which the motor vehicle door handle arrangement is installed.
  • Motor vehicle doors usually have a side window that is in particular retractable.
  • a correspondingly designed motor vehicle door handle arrangement it can be positioned such that the side window and or a body part of the motor vehicle door forms the abutment, which acts as a blocking element after plastic deformation of the motor vehicle door handle arrangement and blocks the bellcrank.
  • the term of the motor vehicle door handle arrangement is not restricted, for example, to a motor vehicle door handle housing, but rather means the overall arrangement of the motor vehicle door handle in the motor vehicle door, which in particular comprises a body part of the motor vehicle door serving as an abutment and / or a pane serving as an abutment, in particular one retractable window of the motor vehicle, includes.
  • the abutment preferably blocks the deflection lever such that rotation of the deflection lever about its axis of rotation into the actuating position is impossible.
  • the deflection lever has at least one cam and / or at least one recess on its circumference, which cooperates with the abutment after plastic deformation of the motor vehicle door handle arrangement.
  • the deflection lever can have at least one cam on its circumference, which is formed by at least one circumferential section on the circumference of the deflection lever with an enlarged radius.
  • the bell crank can be configured such that, in the case of an undamaged motor vehicle door handle arrangement, such a cam swings past the abutment around the axis of rotation of the bell crank during rotation of the bell crank, the distance of the axis of rotation of the bell crank from the bell crank being reduced due to plastic deformation and thereby the deflection lever is blocked by the cam running on the circumference of the deflection lever at a reduced distance from the axis of rotation to the abutment against the abutment and being blocked by the latter.
  • the deflection lever can have a cam which is formed by at least one elevation on the deflection lever which extends parallel to the axis of rotation of the deflection lever.
  • a cam which extends on the deflection lever in a direction parallel to the axis of rotation of the deflection lever, can then be brought into engagement with a corresponding abutment after plastic deformation of the motor vehicle door handle arrangement, by the cam running against the abutment and thereby blocking rotation of the deflection lever.
  • the motor vehicle door handle arrangement preferably has a handle which can be shifted from a rest position into an open position, a handle hook arranged on the rear of the handle being kinematically coupled to the bellcrank lever and, when the handle is shifted to the open position, causing the bellcrank lever to rotate into its actuating position.
  • the handle when the motor vehicle door lock is unlocked, the handle is gripped by the user to open the motor vehicle door and is shifted from a rest position into an open position.
  • the handle has a handle hook on its back, which is kinematically coupled directly or indirectly to the bell crank.
  • the kinematic coupling of the handle to the bell crank causes the bell crank to rotate about its axis of rotation from the rest position to the Activated position of the bell crank causes the motor vehicle door to open when the motor vehicle door lock is unlocked.
  • the deflection lever and / or a handle which is coupled to the deflection lever, is preferably spring-loaded in the direction of the rest position. Such a spring loading of the bellcrank and / or handle ensures that the bellcrank and the handle are moved back into the rest position after being released by a user, since the bellcrank and the handle are indirectly or directly kinematically coupled.
  • the bell crank is coupled to the motor vehicle door lock via a push rod and / or a pull rod and / or a cable, whereby, when the motor vehicle door lock is not locked, the motor vehicle door lock is opened when the bell crank is rotated into its actuating position.
  • the bellcrank has at least one latching element which, when an external impulse occurs as a result of a side impact, engages with an accident lock and blocks a displacement of the bellcrank and the handle from the rest position into its actuation position.
  • the movable masses, any spring constants when a spring load is applied and the smoothness of the joints of the motor vehicle door handle arrangement and in particular the accident lock are selected so that when a pulse occurs, for example as a result of an accident, the accident lock is so smooth and has a corresponding inertia that first the accident lock comes into engagement with the locking element on the bell crank and thereby blocks the bell crank before the handle and bell crank could be shifted out of the rest position as a result of the pulse.
  • This accident prevention system reliably prevents the door from opening due to an impact or other event.
  • FIG. 1 shows the arrangement in the rest position during Fig. 2 the arrangement in the operating position shows in which the bell crank 10 according to the rest position Fig. 1 in the operating position according to Fig. 2 is displaced by rotation about its axis of rotation 11.
  • the handle 20, which is kinematically coupled to the bell crank 10 is also in Fig. 1 in the rest position, while the handle 20 in Fig. 2 by a rotation about its axis of rotation 23 in the actuating position for opening the motor vehicle door, not shown.
  • the bell crank 10 is kinematically coupled to the end of the mandrel 21 on the handle 20 by the axle stub 22 which engages in corresponding receptacles on the bell crank 10. This means that by moving the handle 20 from the rest position according to Fig. 1 in the Operating position according to Fig. 2 Via the kinematic coupling, the bell crank 10 simultaneously around its axis of rotation 11 from the rest position according to Fig. 1 in the operating position according to Fig. 2 is shifted.
  • the bell crank 10 is connected via a Bowden cable, not shown, to a door lock, not shown, of a motor vehicle door.
  • a door lock not shown
  • the bell crank 10 is shifted by rotation about its axis of rotation 11 into the actuating position according to FIG Fig. 2 If the door lock is not locked, the release of the lock is effected and the motor vehicle door (not shown) can be opened.
  • the handle 20 is in turn mounted rotatably about its axis of rotation 23 in a handle housing, not shown
  • Fig. 3 shows a side view of the area of the bell crank in an enlarged view in the rest position of the bell crank 10.
  • FIG. 3 drawn a section of the abutment 30.
  • the motor vehicle door handle arrangement is not plastically deformed as a result of an accident, so that the cam 12 of the bell crank 10 can pivot past the abutment 30 when the bell crank 10 is rotated about its axis of rotation 11 into the actuating position as indicated by arrow 31.
  • This pivoting of the bell crank 10 about its axis of rotation 11 takes place by corresponding actuation of the handle 20, which engages in corresponding receptacles on the bell crank 10 via the pins 22 arranged on the mandrel 21 and the bell crank 10 about its axis of rotation 11 as indicated by the arrow 31 against the Turned clockwise when the handle 20 is moved to its operating position.
  • Fig. 4 The operation of the abutment 30 is clearly shown in Fig. 4 , in which an enlarged section of the area of the bell crank 10 after a plastic deformation of the motor vehicle door handle arrangement as a result of an accident is shown.
  • the abutment 30 serves as a blocking element with respect to the cam 12 of the bell crank 10, so that turning the bell crank 10 into the actuating position about the axis of rotation 11 is no longer possible due to the interaction of abutment 30 and cam 12 of the bell crank 10.
  • the cam 12 can no longer pivot past the deflection lever 10 past the abutment 30, so that the deflection lever 10 accordingly corresponds to its rest position Fig. 1 is blocked.
