Definitions

  • the invention relates to a lock for the door of a motor vehicle of the kind which comprises a locking pawl articulated on an axis and suitable for retaining, in the locking position, a bolt cooperating with a strike, the lock comprising means for drive of the pawl suitable for erasing it to release the bolt and allow the opening of the door, said lock further comprising electrical control means to ensure deadlocking by making the drive means without effect on the pawl and preventing the opening of the lock from inside the vehicle, in particular by action on a frieze zipper or equivalent member, the lock being arranged so that in the event of an electrical failure the deadlock can be mechanically cleared using 'a key.
  • a motor vehicle door lock comprising a release lever for releasing the pawl, and a locking lever articulated around an axis and carrying an axis passing through a L-shaped opening in the release lever.
  • the "inactive" position of the locking lever as shown in FIG. 1, it is possible to release the pawl, the axis carried by the lever being in the narrow part of the L-shaped opening; in the "active" position of the locking lever, as shown in FIG.
  • This device has, however, the disadvantage of only providing the locking function, that is to say the prohibition of opening the lock by the external control lever while the opening by the internal control is always possible; in addition, it does not provide for the motorization of the conviction and super-conviction functions.
  • the object of the invention is, above all, to provide a lock of this kind which is simple and reliable to manufacture and which requires only a minimum of parts to carry out the addition, in addition to the locking function (cancellation of the external control), of the deadlock function (cancellation of the internal control), the two functions being able to be implemented in a voluntary and distinct manner.
  • the subject of the invention is a lock for a motor vehicle door, comprising a locking pawl articulated on an axis and suitable for retaining, in the locking position, a bolt cooperating with a keeper, the lock comprising means for driving the pawl suitable for erasing it to release the bolt and allow the door to be opened, said lock further comprising control means to ensure deadlocking by making the drive means have no effect on the pawl, the drive means of the ratchet comprising an arm which can move between an active position where this arm can control the rotation of the ratchet, and an inactive position where this arm has no effect on the ratchet, the passage of the arm from the active position to the inactive position being ensured by the deadlock control means, clutch / disengage means being provided between the pawl and the arm, these means being actuated by the displacement t of the arm, and comprising, on the side of one of the two elements constituted by the pawl and the arm, a pin and on the side of the other element a
  • the pin is provided on the pawl and the window is provided on the drive part.
  • the window has an effective zone of reduced angular extent and a neutral zone, closer to the pivot axis of the pawl, of angular extent greater than the possible angular movement of the arm so that the pawl of the pawl cannot reach the ends of this neutral zone when the arm is actuated.
  • the passage of the arm from the active position to the inactive position is controlled by a member pivoting about an axis parallel to the pivot axis of the pawl, this pivoting member having two branches, one of which has an elongated window in which is engaged a lug carried by one end of the arm, opposite the window.
  • the window of the pivoting member has a sufficient angular extent to allow the movement of the arm allowing the opening of the lock, by driving the pawl.
  • the pivoting member is driven by a lever itself driven by a rack, the movements of which are controlled by an electric deadlock motor.
  • the aforementioned lever can be located outside of a sealed housing in which is placed the deadlocking motor and another lever engaged with the rack, and wedged, at its end opposite to the rack, on a journal passing through so watertight a wall limiting the watertight zone where the deadlock motor is located, this pin carrying, on the outside, the drive lever of the pivoting member.
  • the pivoting member may include a tab allowing mechanical action by means of a key, for unlocking the lock in the event of a breakdown of the electric superchanging engine.
  • Figure 1 of these drawings is a partial elevational view of a lock according to the invention, in a state where the arm controlling the pawl is in the active position.
  • Figure 2 shows, similarly to Figure 1, the elements of the lock in the deadlock state, the arm being in the inactive position.
  • FIG. 3 finally, is a partial perspective view of the lock of the invention.
  • a lock S for a motor vehicle door comprising a locking pawl 1 articulated on an axis 2 provided on the vehicle door.
  • the axis 2 is provided on the edge of the door, this axis being horizontal and substantially parallel to the mean plane of the door.
  • the pawl 1 has a hooking spout 3 and is subjected to the action of an elastic return means (not shown) tending to rotate the pawl 1 around the axis 2 in the locking direction, ie in the clock direction according to the representation of FIGS. 1 and 2.
  • the pawl 1 is suitable for retaining, in the locking position illustrated in FIG. 1, a bolt 4 in the form of a fork comprising two branches limiting between them a passage 5.
  • the bolt 4 is rotatably mounted about an axis 6, parallel to axis 2, and also carried by the door.
  • the bolt 4 has, on its periphery, two notches 7 and 8. In the locked position, the spout 3 hooks the second notch 8 of the bolt and retains the bolt in the closed position illustrated in FIG. 1.
  • the bolt 4 is intended to cooperate with a keeper 9 fixed to the vehicle body and constituted, for example, by a rod or an axis 9 perpendicular to the plane of the figure.
  • a keeper 9 fixed to the vehicle body and constituted, for example, by a rod or an axis 9 perpendicular to the plane of the figure.
  • the lock S comprises drive means E of the pawl 1.
  • These drive means E comprise an arm 10 mounted pivoting about the axis 2 of the pawl thanks to an oblong opening 11 whose width is equal to the diameter of the axis 2 but whose length is greater than this diameter, in particular greater than twice the diameter of the axis 2.
  • the longitudinal ends of the oblong opening 11 have the shape of semicircles suitable for conforming to the contour of the axis 2 about 180 °.
  • the arm 10 is thus mounted on the axis 2 with a possibility of translation corresponding to the displacement which brings the axis 2 from the support against one end of the opening 11 (see FIG. 1) to a support against the other end of said opening 11 (see Figure 2).
  • the control in rotation of the arm 10 around the axis 2 is ensured, in particular, by a linkage T schematically shown, which connects a pin 12 to control means of the exterior door handle and / or interior door handle or pull tab type frieze (not shown).
  • the pin 12 is able to move in an elongated window 13, in the shape of an arc of a circle.
  • the window 13 is located above the opening 11, as shown in FIG. 1.
  • clutch / disengage means between the pawl 1 and the arm 10.
  • These clutch / disengage means comprise, on the side of the arm 10, a window 14 having two zones, namely an effective zone 15 and a neutral zone 16.
  • the effective zone 15 is more radially distant from the opening 11 than the neutral zone 16.
  • the angular extent of the zone 15 is less than that of the zone 16.
  • the clutch / declutching means comprise, on the side of the pawl 1, a pin 17 secured to the pawl and engaged in the window 14.
  • the pin 17 cooperates, that is that is to say is in abutment, against a radial edge 15a of the zone effective 15.
  • the pin 17 is in the neutral zone 16 where it can move without cooperating with one of the radial edges of said zone so that a rotation of the arm 10 is not transmitted to the pawl 1.
  • the angular extent of the neutral zone 16 is greater than the possible angular movement of the arm 10 controlled by the linkage T so that the pin 17 of the pawl cannot in any case reach the radial ends of the neutral zone 16 in the event of actuation of the arm 10, using the linkage T, while this arm 10 is in the deadlocking position illustrated in FIG. 2.
  • the passage of the arm from the active position of FIG. 1 to the inactive position of FIG. 2 is controlled by a member 18 mounted to pivot around an axis 19 parallel to the axis 2 of the pawl. This axis 19 is also provided on the door.
  • the member 18 has two branches 20, 21 forming between them an angle of about 80 ° in the example illustrated in the drawings; this member 18 is articulated at the top of the angle formed by the two branches 20, 21.
  • the branch 20, of greater width, is slightly inclined on the horizontal when the arm is in the active position of FIG. 1.
  • This branch 20 comprises, towards its end remote from the axis 19, an elongated window 22, the large dimension, substantially horizontal, is oriented in the direction of the length of the branch 20.
  • This window 22 receives a cylindrical lug 23 fixed to the end of the arm 10 remote from the window 14.
  • the window 22 is slightly curved to allow a angular movement of the lug 23, inside this window, when the arm is driven in the opposite direction of the clock by the linkage T for unlocking the bolt 4 (FIG. 1).
  • the angular movement of the part 18 around the axis 19 is controlled by an electric motor 24, called a deadlock motor, with a vertical axis.
  • the lower end of the motor shaft is provided with a pinion 25 of small diameter cooperating with a toothed sector 26 of larger diameter.
  • the sector 26 is integral in rotation with another pinion 27, coaxial (see FIG. 3), which meshes with a rack 28 which can move in translation in a horizontal direction parallel to the plane of Figure 1, that is to say orthogonal to the direction of the axes 2 and 19.
  • the rack 28 is integral with a part 29 having a notch 30 in which is engaged the rounded end 31 of a lever 32. This lever 32 is locked in rotation, at its opposite end, on a pin 33 perpendicular to the plane of the lever.
  • the assembly of parts formed by the motor 24 and the mechanical transmission 25 to 32 is advantageously enclosed in a sealed casing very roughly suggested by walls W in FIG. 3.
  • the pin 33 passes in leaktight manner through one of the partition walls W for transmit outside (in a non-sealed area where the member 18, the arm 10, the pawl 1 and the bolt 4 are located) the rotational movement imparted by the lever 32 from the translational movements of the rack 28
  • FR-A-2 656 030 For more details concerning such an arrangement, reference may be made to FR-A-2 656 030.
  • the pin 33 is integral in rotation with another lever 34 (Figure 3) which extends substantially parallel to the lever 32 and in the same direction, but whose length is shorter.
  • lever 34 has a lug 35 protruding from the side opposite the lever 32, parallel to the pin 33. This lug 35 is received in a notch 36 provided at the end of the branch 21.
  • the notch 36 has a length greater than the height of the lug 35 to allow a certain longitudinal movement while the width of this notch corresponds substantially to the thickness of said lug 35.
  • a rotation of the lever 34 ensures the drive of the member 18 in rotation around axis 19.
  • the member 18 further comprises, on the upper edge of its branch 20, a projecting tab 37 extending perpendicular to the mean plane of the branch 20.
  • the tab 37 is intended to cooperate with its own mechanical means (not shown) to be controlled by a key actuated manually to allow unlocking of the lock in the event of an electrical failure at the level of the overlocking motor 24.
  • Figure 1 corresponds to the normal operating state of the lock.
  • the arm 10 is in the active position. If the user acts on the linkage T from inside or from outside the vehicle, it causes the arm 10 to rotate in a counterclockwise direction around the axis 2. The cooperation of the edge 15a of the zone 15, with the pin 17, causes the pawl 1 to rotate in the counterclockwise direction around the axis 2, which ensures the release of the bolt 4 and allows the door to be opened.
  • the user controls the deadlocking by starting the electric motor 24, for example using a remote control.
  • the motor 24 starts to rotate in the proper direction and drives [by the transmission mechanism constituted by the pinion 25, the toothed sector 26 and the pinion 27 (FIG. 3)], the rack 28 to the right, in the example considered, as illustrated in Figure 2.
  • the lever 32 pivots clockwise around the geometrical axis of the pin 33.
  • This pin 33 drives the other lever 34 (see FIG. 3) which, by cooperation with the branch 21, makes the member 18 rotate in clockwise around the axis 19.
  • the amplitude of this movement is such that the upper end of the opening 11 bears against the axis 2 as illustrated in FIG. 2.
  • This movement of the arm 10 has released the pin 17 from the zone 15 to make it enter the neutral zone 16 where it is substantially in the middle part, when the arm 10 is not actuated by the linkage T.
  • the authorized user can erase the deadlock corresponding to the representation of FIG. 2, using a key which acts on a mechanism cooperating with the lug 37.
  • the member 18 is then mechanically brought back from the position of FIG. 2 to that of FIG. 1.
