Definitions

  • an invention provides a latch arrangement as defined in Section C.1 , Claim 1 , referred to as Claim C.1.1.
  • an invention provides an automobile door latch having a deadlocking arrangement, as defined in
  • an invention enables the number of key mechanisms to be reduced, by coupling plural latches to one key mechanism in accordance with the invention of Claim C.4.1.
  • Existing door latches for vehicles generally include components within a housing, and components extending outside the housing which make the arrangement bulky. As shown for example in Kiekert US Patent No. 5419597, the levers which cause the latch to release and the door to open, and which are connected to door handles by cables, generally project from the latch housing.
  • Door latches typically comprise housings to which components are permanently riveted, so that the door latch cannot be disassembled non- destructively.
  • An invention overcomes this problem, and also simplifies the process of assembly, by providing a latch assembly whose housing has a retaining means for retaining parallel plates releasabiy, in accordance with Claim C.6.1.
  • an invention enables such actuation to be continued fully to completion once the handle has been released, without the need to repeat the actuation.
  • the invention provides a latch arrangement as defined in Claim C.7.1.
  • an invention provides a latch assembly as defined in Claim C.9.1.
  • an invention as defined in Claim C.10.1 , provides for the selective coupling of interior or exterior door handles, for example, to the door opening mechanism of the latch arrangement, under the control of a common electric motor. This is particularly advantageous as it provides electric control independently of each door handle, and thereby avoids the need to use a mechanical control for child-safety locking. Accordingly, an invention provides a latch arrangement as defined in Claim C.10.1.
  • Some existing door latch arrangements provide for so-called panic door opening, by which the door can be unlocked by the operation of the interior door handle without the need to lift the interior door knob. The door then remains unlocked to ensure that the door can be opened by the exterior door handle. This prevents inadvertent locking out of the vehicle by the occupant.
  • the door latch will be unlocked when the vehicle is in motion, but there may be circumstances in which it is locked with the vehicle stationary or even moving.
  • the invention of Claim C.11.1 enables panic door opening to be provided in a latch arrangement of compact and simple design.
  • a particularly important invention is the combination of electric locking and electric door latch release (door opening) using a common electric motor, and this is provided by the invention of Claim C.12.1.
  • the invention of Claim C.13.1 also provides electrically-powered door closing, using the same electric motor.
  • latch arrangements provide selective electrical control of interior or exterior door handles, for example, for door opening, and preferably they also provide electrically-operable child-safety.
  • Latch arrangements typically comprise a latch bolt, for engaging a fixed striker in the door frame, and a latching pawl for releasably holding the latch bolt so as to latch the bolt. Electric door opening can then be achieved by actuating the latching pawl.
  • a particularly beneficial arrangement for electrical door latch release and door opening using a linear actuator acting directly on the latch pawl, this arrangement allowing independent door opening by external mechanical means such as the door handle.
  • This invention is defined in Claim C.16.1.
  • An alternative beneficial arrangement for electrical door latch release on manual door opening, using a rotary actuator acting directly on the latch pawl, is defined in Claim C.17.1.
  • anti-slam latching is achieved differently, by ensuring that an actuator is prevented from moving within the latching arrangement whenever the arrangement is unlatched and the door open.
  • the latching arrangement has a fixed formation which co-operates with the coupling actuator only at its unlocking configuration.
  • cables are used to link the latching arrangement with door handles and key mechanisms and the like.
  • Conventional means for coupling cable ends to actuator arms comprise special formations on the arms for engaging a cylindrical nipple at the end of the cable.
  • the invention of Claim C.22.1 enables the use of a simple planar blank to form the appropriate actuator arm. A flange at the end of the blank is folded over to define an appropriate formation for receiving and retaining the nipple whilst still allowing it to rotate freely.

  • Figure 50 is a perspective view of a clutch-actuating lever of the clutch mechanism shown in Figure 49.
  • Motor Vehicle with Central Locking Figures 1 and 2 illustrate a conventional arrangement for locking vehicle doors and other closures.
  • Latches L1 to L4 are bolted on to each of the four passenger doors, latch L5 on to the tailgate (boot) and latch L6 to the petrol locking cap.
  • the vehicle battery is connected to a central electronic control system 90 which in turn is connected by electric cabling (not shown) to the latches.
  • each door has interior and exterior handles, a key mechanism, usually in the form of a cylindrical key mechanism, and an interior door knob which is constrained to move linearly between an unlocked position, at which the knob projects from the door frame, and a locked position, at which it projects only slightly from the door frame.
  • a striker in the form of a cylindrical bar, is fixed vertically in the door frame.
  • the door latch arrangement L1 is bolted to the door such that a latch bolt, described in more detail below, engages the striker to hold the door in its closed position.
  • a door has a resiliently-deformable seal (not shown) which is deformed as the door closes against the frame, and which causes the door to open as soon as the striker is released by the latch bolt.
  • the latch bolt is normally spring biased to the open position so that it opens the door.
  • This position sensing provides the necessary information for the control of most electrical functions connected with door locking, closing and opening, and, although not always specified in the following description, it is included in most latch arrangements.
  • the electric motor is controlled to operate the pawl to release the latch bolt, for electrical door opening. It is also controlled to selectively couple the exterior handles and knobs to operate the pawl appropriately. However, in some arrangements, separate electric motors may be provided for this purpose, depending on design requirements and space availability.
  • the central electronic control circuit 90 is shown in Figure 4, together with the electric motors shown as A for the four doors and the tailgate and filler (petrol) cap catch; also for the engine compartment catch (bonnet catch).
  • the interior lock is operated simply by an electric switch R6, avoiding the need for an interior door knob, although such a knob could also be provided.
  • the function of this circuit need not be described in detail here, but is described more fully in WO97/28338, referred to above.
  • the electrical control system will now be described with reference to
  • the microswitch actuators are at the top right hand corners of the cam tracks shown in Figure 6. As the door begins to close, their relative positions move in the direction shown by Letter L, to the positions shown as A, B, C in Figure 6. At this point, the door is fully closed.
  • NO represents the normally open terminal
  • NC represents the normally closed terminal
  • C represents the common terminal.
  • the microswitch actuators are at positions A, B and C in Figure 6, and all microswitches are off. Movement towards the opening position causes motion of the microswitch actuators in the arrow K of Figure 6, and after a small neutral movement, microswitch 130 is switched on, as actuator 131 rides up the ramp E.
  • This provides power assisted door opening. Whilst the door is being opened, the door hazard light control microswitch comes on, as actuator 111 rides up its own ramp. When the door has reached the end of the power assisted motion, the door opening microswitch 130 is switched off, and only the door hazard light remains on. As the door is reclosed, the door closing control microswitch is immediately switched on, as the actuator 121 rides up its ramp from line F of Figure 6. During door closure, the hazard light is switched off.
  • FIG. 10 An alternative form of door opening arrangement is shown in Figure 10.
  • the electric motor 70 output drive takes the form of a rack and pinion arrangement 31 producing linear drive in the direction D1 , with part of the rack abutting against the pawl 20.
  • the electric motor is either switched off, or else powered in the reverse direction, to bring the rack 31 back to its neutral position as shown in Figure 10.
  • the rack remains in its door-opening position until the door is shut. Shutting the door causes the pawl to rotate to its latch engaging position, simultaneously driving the rack back to its neutral position. This is assisted by the spring biasing of the pawl 20.
  • Tailgate and boot latch bolts differ from that illustrated, in that they normally only one notch 13, for fully latching the bolt. Again, various alternative gearing arrangements would of course be possible.
  • This arrangement is capable of being accommodated in a single housing which is compact and simple to produce, improving on sound proofing and reducing manufacturing costs.
  • the latch arrangement of Figure 12 is a variant of that of Figure 11 , for door opening and closing.
  • the actuator plate 41 which replaces plate 38, is arranged to slide over the pivot axis 43 of the rotary indexing and driving member 50; it has a slot 45 which guides it over the pivot 43.
  • the actuation plate 41 has an end flange 44A depending downwardly for abutting engagement with the pin 34 of the rotary member 50.
  • the actuator plate 41 is capable of sliding between positions C and C1 , corresponding to the latched and unlatched positions respectively of the pawl 20.
  • This arrangement has the further advantage of complete independence of the mechanical door opening and closing from the electrical arrangement, at all stages of electrical door opening. It also has the advantages of enabling use with a relatively small motor, due to the high gearing ratio, and is extremely adaptable and simple.
  • the compression-tension spring provides an anti-backlash arrangement which reduces noise by absorbing the inertia of the mechanism after the motor has been switched off; this also prolongs the life of the drive mechanism.
  • FIG. 17 A further modification of the previously-described electrical door opening and closing latch arrangements is shown in Figure 17.
  • the actuator plate 202 is connected pivotally at 203 to the pawl 20 near to the point of engagement with the latch bolt 11. It therefore operates in the reverse direction, as there is no lever action.
  • This actuator plate 202 is constrained to rotate about the pivot axis of the rotary indexing and driving mechanism 50, or to move linearly in the actuation direction D4, by virtue of an end fork with limbs 205 and 206 on either side of the pivot axis.
  • the cam pin 34 is replaced by an arrangement of radial cams all integral with the rotary mechanism 50 and arranged in two separate planes normal to the pivot axis.
  • the latch arrangement of Figure 18 importantly illustrates the use of one electric motor 70, and one rotary indexing and driving mechanism 50, to control independently the door opening and closing mechanism on the one hand, and electric locking, on the other hand.
  • the door opening and closing mechanism involves a shuttle 215 constrained to move linearly, and coupled to a tension- compression spring 218, as previously described in relation to Figure 14.
  • the rotary member 50 has a single cam pin 34 which is rotatable in either direction D1 , D5 between two neutral positions Np1 and Np2, at which it is retained respectively by W-shaped fixed springs 220 and 219.
  • the pawl 20 can alternatively be released manually by externally operable means such as the handle through a lever 246 and cable 245.
  • the distal end 20A of the pawl 20 is elevated by bending so that it can override the latch bolt extension 37.
  • This particular arrangement enables a reduction in the drive torque and renders it more adaptable.
  • the arrangement of Figures 19-21 provides electric door opening by which the pawl is first released and then the latch bolt is driven under electric power to ensure that it opens fully.
  • the arrangement also provides for powered door closing, as with arrangements described above.
  • Notch 13 is for locking the latch bolt at a latching rotary position, which retains the striker 10 and maintains closed the vehicle door.
  • the door is capable of being opened, towards the right in Figure 1 , by releasing the pawl 20 from its locking position in notch 13, allowing the striker 10 to drive the latch bolt 11 clockwise 18 under the camming action of the indentation 12, until it is no longer detained by the striker 10.
  • the locking pawl 20 is allowed to engage the further notch 14, at a so-called half latch position, then the door can be half latched, partially open.
  • the locking pawl 20 is mounted pivotally at 21 , and pivot points 15 and 21 are both fixed to a latch housing (not shown).
  • the latch bolt 11 is coupled drivingly to an electric drive motor 70, of the type commonly used for the central locking of vehicle doors.
  • This coupling arrangement also incorporates an arrangement for releasing the pawl.
  • Electronic position sensors to be described below, cause the motor drive to switch off at the point that the vehicle door is partially open, and has passed its unlatched position. The door can then conveniently be opened fully by the passenger or driver.
  • a portion 244 of the pawl is connected by a link 245 to an external manual control such as a handle through a lever 246, to enable the door to be opened provided first the latch has been unlocked by a key mechanism, an interior door knob or an electrical control (not shown).
  • the nut 243 and shuttle returns after each actuation to its neutral position, as shown, by at least one of the following mechanisms: a return spring acting on the nut; a return nut acting on the pawl; and repowering the motor so as to cause the nut to move in direction D6.
  • the nut 243 is constrained to move linearly, by suitable means such as rails fixed to the housing.
  • the leadscrew 240 meshes with an internal thread 241 in the rotary drive gear 50, and the leadscrew is formed integrally with the shuttle 242. Further mechanical equivalent configurations will occur to the skilled reader.
  • the rotary coupling member 300, 400 comprises two components connected pivotally at the pivot axis 21 but capable of sliding movement, normal to the pivot axis, by virtue of an oval slot formed in both components 300, 400.
  • Locking member 300 is constrained to move linearly between the left-most position as shown in Figure 24, at which the door is unlocked, and a right-most position at which the door is locked because the pawl release lever 225 is no longer coupled to the pawl 20, i.e. it is rendered neutral.
  • each latch arrangement has a further lever 900 connected to an external control mechanism through a cable 901 , such as to a child-safety switch, or an interior door knob, depending on whether the arrangement is to be used in a rear door or a front door.
  • This further lever 900 has a pivot point at 902 within the housing, and is connected to a lever arm with an end pin 903 coupling with an appropriate one of the rotary coupling members.
  • Rotary coupling member 350, 450 has a lug 451 on the left-hand side which is capable of being driven clockwise by notch 702 on pawl release lever 700. As mentioned above, it is also coupled pivotally to lever 900 through pin 903.
  • the rotary sliding member 450 is formed with a notch 452 capable of being driven clockwise by a lug 802 on the pawl release lever 800. It is also formed with the notch 453 which drives lug 410 of the other rotary sliding member 400, when at its left-most position.
  • the cam pin 30 In order to allow the passage of the cam pin 30, they are resiliently moveable outwardly to the corresponding extreme positions A, A3, B and B3.
  • the resilience is achieved, as shown in Figure 35, by arranging for the projection on the locking members 300, 350 to take the form of a toggle 1050 pivoted at 1052 and biased into its central position by torsion spring 1053 disposed on the pivot and held by and held by fixed block 1054.
  • the toggle or finger 1050 can be displaced rotationally to position P1, to be returned to its neutral position P, by spring arm 1051.
  • it can be displaced to position P2 to be returned to its neutral position by spring arm 1055.
  • a conventional key mechanism is coupled to the latch by means of a cable or a rod or lever.
  • Some cylinder key mechanisms as shown in Figure 44 have a radial arm
  • Two parallel guide rails 458, 459 are fixed to the latch housing, and are of equal length but displaced linearly as shown.
  • the door In the unlocked position as shown in Figure 45, the door can be locked by the key mechanism moving in direction D1 , causing the pin 457 to follow line BB. It can then only be unlocked by the key mechanism, by reversing the process. If unlocking is attempted by lifting the interior door knob 452 in direction D3, the lever 453 is rotated in direction D4 so that the pin moves to position 457A at which it abuts and is retained by the right hand guide rail 458. This constitutes double locking, dead locking or super locking.
