Definitions

  • the present invention relates to closure latches for vehicle doors, and more particularly to closure latches for tall or wide vehicle doors, such as cargo doors on certain types of vans.
  • a typical vehicle door has a closure latch that includes a ratchet that captures a striker on the vehicle body during closure of the door so as to hold the door in a closed position.
  • Certain types of vehicle door are relatively tall or wide. While the door edge immediately adjacent the ratchet and striker is securely closed against the vehicle body, the portions of the door edge that are relatively far from the ratchet and striker are not as securely closed, and can be compromised either by sufficient force outwards by a load carried inside the vehicle, or by a vehicle thief from outside the vehicle.
  • EP 1 953 317 A2 discloses a double latch assembly for a motor vehicle having two pivotably mounted closure members, in which a sequencing lever is used to release first and second pawls used to hold first and second rotatable claws in respective latched positions.
  • a single actuator is used to release both of the pawls but because of the use of a disengageable coupling between the sequencing lever and the second pawl it is ensured that the first pawl is always released before the second pawl. Only a single actuator is required to release both pawls and no sensors are required to control the sequencing of the pawls.
  • EP 0 022 604 A1 discloses a dual latching mechanism for latching two spaced locations of a flexible lid to a pair of similarly spaced anchors of a compartment to which the flexible lid is movably mounted.
  • the latching mechanism has two latches mounted on the lid by housings each including a pawl pivotally mounted which is spring biased for movement, when released, to an anchor release position and a blocking dog which is spring biased to a pawl blocking position for locking the pawl to its respective anchor.
  • the latches are interconnected by a latch control which includes two rigid links each link having its outer end connected pivotally to a blocking dog and each having its inner end connected by way of an actuator pin to a key operated lock cylinder which is mounted on the flexible lid.
  • the rigid links are connected so as to maintain axial rigidity for operating the two latches concurrently while having the required flexibility necessary to operate two latches on a flexible lid.
  • DE 103 59 737 A1 discloses a motor vehicle locking device with an additional lock including a rotating trap that retraces swivel path of closing link of additional lock and is locked with link when main lock is released.
  • the invention is directed to a closure latch system for a vehicle door that is closable against two spaced apart strikers. Closing the door against the two spaced apart strikers permits a vehicle door that is relatively tall or relatively wide to more securely be closed.
  • the closure latch system includes two spaced apart ratchets which are mechanically connected and controlled via a single point. Both ratchets may be opened via a single outside door handle (if provided), or a single inside door handle (if provided), and are lockable and unlockable together (if locking is provided). However, each ratchet is openable and closable independent of the opening/closing state of the other ratchet so that there does not need to be precise timing or synchronization between the opening and closing of the two ratchets relative to each other.
  • the invention is directed to a closure latch system for a vehicle door including a first ratchet, a first pawl, a second ratchet, a second pawl and a common actuator.
  • the first ratchet is movable between a closed position wherein the first ratchet is positioned to retain a first striker and an open position wherein the first ratchet is positioned to permit release of the first striker.
  • the first ratchet is biased towards the open position.
  • the first pawl is movable between a ratchet locking position wherein the first pawl holds the first ratchet in the closed position and a ratchet release position wherein the first pawl permits the first ratchet to move to the open position.
  • the first pawl is biased towards the ratchet locking position.
  • the second ratchet is movable between a closed position wherein the second ratchet is positioned to retain a second striker and an open position wherein the second ratchet is positioned to permit release of the second striker.
  • the second ratchet is biased towards the open position.
  • the second pawl is movable between a ratchet locking position wherein the second pawl holds the second ratchet in the closed position and a ratchet release position wherein the second pawl permits the second ratchet to move to the open position.
  • the second pawl is biased towards the ratchet locking position.
  • the common actuator is movable between a rest position and an actuating position.
  • the common actuator In the rest position the common actuator permits each of the first pawl and second pawls to move between the ratchet locking and ratchet release positions independent of the other of the first and second pawls. In the actuating position the common actuator drives the first pawl to the ratchet release position and drives the second pawl to the ratchet release position.
  • the common actuator and the first pawl are rotatable about a common axis.
  • Figure 1 shows a closure latch system 10 for a vehicle door 12 of a vehicle 16, in accordance with an embodiment of the present invention.
  • the vehicle door 12 is a cargo door of a van.
  • the closure latch system 10 permits the vehicle door 12 to close by engagement of a first ratchet 18 with a first striker 19, and by engagement of a second ratchet 22 with a second striker 23.
  • a closure latch system with first and second ratchets 18 and 22 which are at selected vertical positions on the vehicle door, provides more secure closure of the vehicle door 12.
  • the first and second ratchets 18 and 22 are connected by a mechanical linkage that further makes up part of the closure latch system 10 including a first pawl 20, a second pawl 24, a common actuator 26, an outside door release lever 28, an inside door release lever 30 ( Figure 5 ) and a door locking member 32.
  • the first ratchet 18 is movable between a closed position ( Figure 3a ) and an open position ( Figure 3d ). In the closed position, the first ratchet 18 retains the first striker 19. In the open position ( Figure 3d ) the first ratchet 18 is unengaged with the first striker 19.
  • a first ratchet biasing member 38 such as a suitable spring may be provided to bias the first ratchet 18 towards the open position.
  • the first pawl 20 is movable between a ratchet locking position ( Figure 3a ) and a ratchet release position ( Figures 3b and 3c ). In the ratchet locking position the first pawl 20 holds the first ratchet 18 in the closed position. In the ratchet release position the first pawl 20 permits the first ratchet 18 to move to the open position.
  • a first pawl biasing member 40 ( Figure 2a ) such as a suitable spring may be provided to bias the pawl 20 towards the ratchet locking position.
  • the second ratchet 22 may be similar to the first ratchet 18.
  • the second ratchet 22 is movable between a closed position ( Figure 4a ) and an open position ( Figure 4d ). In the closed position, the second ratchet 22 retains the second striker 23. In the open position ( Figure 4d ) the second ratchet 22 is unengaged with the second striker 23.
  • a second ratchet biasing member 44 such as a suitable spring may be provided to bias the second ratchet 22 towards the open position.
  • the second pawl 24 is movable between a ratchet locking position ( Figure 4a ) and a ratchet release position ( Figures 4b and 4c ). In the ratchet locking position the second pawl 24 holds the second ratchet 22 in the closed position. In the ratchet release position the second pawl 24 permits the second ratchet 22 to move to the open position.
  • a second pawl biasing member 46 such as a suitable spring may be provided to bias the second pawl 24 towards the ratchet locking position.
  • the common actuator 26 is operatively connected to both the first and second pawls 20 and 24 to move them to their respective ratchet release positions.
  • the common actuator 26 is a lever that is rotatable about a common actuator axis 48, and is movable between a rest position ( Figures 3a , 3d , 4a and 4d ), and an actuating position ( Figures 3b , 3c , 4b and 4c ).
  • a common actuator biasing member 50 such as a suitable spring biases the common actuator 26 towards the rest position.
  • the common actuator 26 contains a pair of slots 52 each of which are oriented about the common actuator axis 48. Each slot 52 is defined by a slot wall 54.
  • the first pawl 20 rotates about the same axis 48 as the common actuator 26, and so the common actuator axis 48 may also be referred to as a common axis, and as a first pawl axis.
  • the first pawl 20 has a pair of slot travelers 56 that are moveable in the slots 52, permitting the first pawl 20 to rotate from the ratchet locking position to the ratchet release position while the common actuator 26 remains in the rest position.
  • the common actuator 26 could alternatively be provided with one slot 52 and the first pawl 20 could be provided with one slot traveler 56 instead of two. Alternatively, some other number of slots 52 and slot travelers 56 could be provided. The engagement of the slot-travelers 56 and the slots 52 is discussed further below.
  • the common actuator 26 is connected to the second pawl 24 ( Figure 2a ) by means of a mechanical linkage 68.
  • the mechanical linkage 68 may be made up of any suitable combination of components.
  • the linkage 68 includes an intermediate release lever 70 and a cable 74 connected between the release lever 70 and the second pawl 24.
  • the intermediate release lever 70 is engaged directly by the common actuator 26.
  • Movement of the common actuator 26 to the actuating position ( Figure 4b ) drives the intermediate release lever 70 from a rest position to an actuating position, which in turn pulls the cable 74, which in turn pulls the second pawl 24 to the ratchet release position, which permits the second ratchet 22 to move to the open position ( Figure 4c ), thereby releasing the second striker 23.
  • An intermediate release lever biasing member 76 such as a suitable spring, biases the intermediate release lever 70 towards its rest position permitting the second pawl 24 to return towards its ratchet locking position under the urging of the second pawl biasing member 46.
  • the vehicle door 12 When a person opens the vehicle door 12 (eg. by pulling on the door handle 75 ( Figure 1 ) they may received a greater amount of tactile feedback relating to the release of the first ratchet 18 than they receive concerning the second ratchet 22.
  • One or more factors may cause this. For example there may be a more direct connection between the outside door handle 75 and the first ratchet 18 than there is between the door handle 75 and the second ratchet 22.
  • the first ratchet 18 may be positioned relatively close to the door handle 75, whereas the second ratchet 22 may be positioned relatively far away proximate the top of the door 12.
  • a person may have a tendency to pull the door 12 open as soon as they sense the release of the first ratchet 18, since they may be accustomed to opening a typical vehicle door, which only has one ratchet. If the second ratchet 22 were not open when the person pulls on the door 12, their force on the door 12 could in some embodiments prevent the second ratchet 22 from opening. To reduce the likelihood of this from occurring, the movement of the common actuator 26 towards its actuating position causes the second pawl 24 to release the second ratchet 22 before the first pawl 20 releases the first ratchet 18.
  • the outside release lever 28 has a pivot connection with an outside link 58, though which it is removably engageable with the common actuator 26.
  • the inside release lever 30 ( Figure 5 ) has a pivot connection with an inside link 78, through which it is removably engageable with the common actuator 26.
  • the positions of the outside link 58 and the inside link 30 are controlled by a locking member 80 that passes through them.
  • a first cam portion 82 on the locking member 80 controls the position of the outside link 58.
  • a second cam portion 84 on the locking member 80 controls the position of the inside link 78.
  • the first and second cam portions 82 and 84 move both the outside link 58 and the inside link 64 to disengaged positions, so that both the outside and inside release levers 28 and 30 are disengaged from the common actuator 26.
  • the position of the locking member 80 may be controlled by an electric motor (not shown) or by some other means.
  • the outside release lever 28 is movable between a rest position ( Figure 3a ) and an actuating position ( Figure 3b ). In the rest position, the outside release lever 28 permits the common actuator 26 to be in its rest position.
  • movement of the outside release lever 28 from the rest position to the actuating position drives the common actuator 26 from the rest position ( Figure 3a and 4a ) to its actuating position ( Figures 3b , 3c , 4b and 4c ), releasing the first striker 19 from the first ratchet 18 ( Figure 3c ) and releasing the second striker 23 from the second ratchet 22 ( Figure 4c ), thereby opening the vehicle door 12.
  • An outside first release lever biasing member 60 biases the outside release lever 28 to its rest position.
  • the outside release lever 28 is itself actuatable by the outside door handle 75 (through any suitable direct or indirect connection).
  • the locking member 80 is in the outside locking or double locking positions (not shown), the movement of the outside release lever 28 to its actuating position does not move the common actuator 26 from its rest position.
  • the operation of the inside release lever 30 may be similar to the operation of the outside release lever 28, although the inside release lever 30 continues to be able to move the common actuator 26 to the actuating position when the locking member 80 is in the outside locking position.
  • the first ratchet 18, the first pawl 20 and the common actuator 26 are in the positions shown in Figure 3d and the second ratchet 22, and the second pawl 24 are in the positions shown in Figure 4d .
  • the slot travelers 56 are positioned away from the ends of the slots 52.
  • Closing the vehicle door 12 causes the first and second strikers 19 and 23 to drive the first and second ratchets 22 to their closed positions, not necessarily at precisely the same instant.
  • closing of either of the first and second ratchets 18 and 22 can take place independent of the position of the other of the first and second ratchets 18 and 22.
  • one or both of the first and second ratchets 18 and 22 can be in a secondary closed position (ie. not fully closed) without affecting the position of the other.
