[0032] A detailed description of one or more embodiments of the disclosed apparatus and methods is given herein by way of example and not limitation with reference to the accompanying drawings.
[0033] According to the present disclosure, the ejector lever is riveted and pivoted into the take-up lever. The ejector lever will have a pivot riveted to the ejector lever that acts as a guide feature. In addition, the ejector lever will be spring loaded or biased so that whenever the take-up lever is rotated, it will fall into the bypass path unless it is redirected by the clutch lever.
[0034] Therefore, each time the take-up lever is turned, the ejection lever will follow two possible paths: an ejection path or a bypass path. The path the ejection lever will take will be determined by the latch position (e.g., held open). The pivot riveted to the ejection lever will slide through these paths.
[0035] The clutch lever is pivotally mounted on the latch and will move when the latch is in a hold open position. As used herein, hold open means when the latch's pawl is held in an open or disengaged position, wherein the pawl does not contact the latch's claw. The clutch lever will allow the ejector rod to follow the ejector path in the latch housing, thereby causing contact between the ejector rod and the claw.
[0036] If the latch is not in the hold open or open position, the ejector rod will only follow the bypass path.
[0037] Whenever the push-out rod contacts a blank portion of the claw, it will have the ability to move it out of the secondary position.
[0038] The design also eliminates the possibility of simultaneous tightening and assisted opening operations.
[0039] Now refer to Figure 1 , a vehicle latch assembly 10 is shown. The vehicle latch assembly 10 includes a vehicle latch 12 operably coupled to a remote tightening actuator 14 via a cable that is slidably received in a cable sheath 16 extending from the vehicle latch 12 to the remote tightening actuator 14. In one non-limiting embodiment, the vehicle latch assembly 10 is configured for use with a side door of a vehicle.
[0040] Figure 2The vehicle latch 12 is shown with the cover 18 removed from the latch housing 20. Referring now to Figure 1-Figure 4 ,in particular Figure 3 and Figure 4 , showing a portion of the vehicle latch 12. Specifically, Figure 3 and Figure 4 An exploded view of a portion or assembly of a vehicle latch 12 is illustrated. An override link 22, a back plate 24, a clutch lever 26, a clutch lever spring 28, a take-up lever 30, a take-up link 32, an ejector lever 34, and an ejector lever spring 36 are shown. The take-up lever 30 is pivotally or rotationally mounted to the latch housing 20 by a pivot 38. The take-up link 32 is pivotally mounted to the take-up lever 30 by a rivet 40, and the ejector lever 34 is pivotally mounted to the take-up lever 30 by a rivet 42. The ejector lever 34 has a pivot or feature 44 riveted thereto that will serve as a guide feature for the ejector lever 34. The clutch lever spring 28 provides a biasing force to the clutch lever 26, and the ejector lever spring 36 provides a biasing force to the ejector lever 34. The clutch lever 26 is pivotally mounted to the back plate 24. One end of the clutch lever spring 28 contacts or is fixed to the clutch lever 26, and the other end contacts or is fixed to the back plate 24. One end of the ejection rod spring 36 is in contact with or fixed to the take-up rod 30 , while the other end of the ejection rod spring 36 is in contact with or fixed to the ejection rod 34 .
[0041] Now refer to Figure 5 , shows an enlarged portion of the override link 22 and clutch lever 26. As shown, the clutch lever 26 has a protrusion or feature 46 received within a recess 48 of the override link 22 so that when the override link 22 is moved, the clutch lever 26 will rotate. The clutch lever 26 also has a guide feature or cam surface 50 that will interact with the pivot or feature 44 and cause the ejector rod 34 to follow one of two paths, namely a bypass path or an open auxiliary path, depending on the position of the clutch lever 26.
[0042] Figure 6-Figure 8 A tightening operation of the vehicle latch 12 is shown. Figure 6-Figure 8 is a bottom view of the latch housing 20 (relative to at least Figures 1 to 3 view of the mounting plate removed). Figure 6 In the embodiment, the pawl 52 is in the secondary position and the ratchet 54 is engaged with the pawl 52 so that it cannot be Figure 6 Position shown to open position or counterclockwise.
[0043] As used herein and as known in the related art, the primary position of the pawl 52 refers to the closed position of the vehicle latch 12, wherein the pawl 52 retains a striker (not shown), and the door with which the vehicle latch 12 is associated is fully closed, and the pawl 54 is in an engaged position that retains the pawl 52 in the closed or primary position. As used herein and as known in the related art, the open position of the vehicle latch 12 refers to the pawl 52 no longer retains the striker, and the door with which the vehicle latch 12 is associated is open or openable, and the pawl 54 has moved to a disengaged position so that the pawl 52 can be rotated from the closed or primary position to the open position. As used herein and as known in the related art, the secondary position refers to the partially closed position of the vehicle latch 12, wherein the pawl 52 retains the striker, and the door with which the vehicle latch 12 is associated is partially closed, and the pawl 54 is in an engaged position that retains the pawl 52 in the secondary position.
[0044] As such, the vehicle latch 12 is configured to perform a powered tightening operation wherein the pawl 52 is urged from the secondary position to the primary or closed position.
[0045] exist Figure 7 In the embodiment of the present invention, the tightening operation has begun, which may be referred to as when the rotational force is applied to the tightening rod 30 by the cable 31, which is fixed at one end to the tightening rod 30, and the drum (not shown) of the remote tightening actuator 14 is driven or rotated by the motor (not shown) of the remote tightening actuator 14, so that the cable 31 is wound around the drum and rotates the tightening rod. During this movement, the tightening link 32 contacts the surface 56 of the claw 52. Therefore, the tightening link 32 will rotate the claw to the position as shown in FIG. Figure 8 The primary or fully locked position is shown. In this position, the pawl 54 holds the pawl 52 in the primary or fully locked position. During this movement, the ejector lever 34 follows a bypass path and does not contact the pawl 52. This is due to the biasing force of the ejector lever spring 36 and the fact that the pivot or feature 44 is not redirected by the guide feature or cam surface 50 of the clutch lever 26. This is also due to the fact that the clutch lever 26 is not moved by the override link. See also Fig. 9 and Fig.10 , which shows the relative Figures 6 to 8 Movement on the other side of the vehicle latch 12 (cover removed). See also Fig. 9A and Fig. 10A , wherein only some components of the vehicle latch 12 are described with respect to at least Figures 6 to 8 This movement is on the opposite side of the vehicle latch 12 (the cover is removed).
[0046] Reference now Figures 11 to 13, the override link 22 moves in the direction of arrow 58. Due to this movement of the override link 22 in the direction of arrow 58, the clutch lever 26 is now moved to a position to prevent the biasing force of the ejector rod spring 36 from causing the ejector rod 34 to travel along the bypass path, where the ejector rod 34 would contact the pawl 52. This position of the clutch lever 26 can be referred to as at least Figure 2 , Fig. 9 , Fig. 9A , Fig.10 and Fig. 10A The non-bypass position or second position and the clutch lever 26 position shown in , may be referred to as the bypass position or first position.
[0047] Reference now Figures 11 to 16B , movement of the override link 22 in the direction of arrow 58 is facilitated by a power release operation, wherein a motor 60 rotates a worm 62, which rotates a power release gear 64, which has a cam feature 70, which contacts and rotates a power release lever 72. The power release lever 72 is operably coupled to a pawl release lever 74. The pawl release lever 74 has a protrusion 76 that is received within an opening 78 of the override link 22. The pawl release lever 74 is operably coupled to a pawl lifter 80, which is operably coupled to the pawl 54. As such, and when the pawl release lever 74 is rotated by the power release lever 72, the pawl 54 is in a position at least as Fig.14 and Fig.15 However, if Fig.14 and Fig.15 As shown, the claw 52 is still in the closed or main position. This may be due to the vehicle door associated with the vehicle latch 12 being frozen or stuck (as described above).
[0048] If this happens, by activating the remote tightening actuator 14, the tightening rod 30 can be moved as shown in FIG. Fig.12 and 13 , the pawl 52 of the vehicle latch 12 can be moved to the open position. However, now the override link 22 has moved in the direction of arrow 58. The clutch lever 26 is moved to the non-bypass position or the second position. This is because the movement of the override link 22 overcomes the biasing force of the clutch spring 28 (it will be appreciated that the clutch spring biases the clutch lever 26 to the bypass position or the first position of the clutch lever) due to the movement of the override link 22 in the direction of arrow 58, and the clutch lever 26 is rotated to the non-bypass position or the second position. When the clutch lever 26 is in the non-bypass position or the second position, and the take-up lever 30 is relative to at least Figures 11 to 13 When rotated clockwise in the view shown in FIG. 8 , the pivot or feature 44 will contact the surface 84 of the clutch lever 26 , and therefore, the ejector lever 34 will not be rotated into the bypass passage by the ejector lever spring 36 .
[0049] Therefore, and as the take-up lever 30 is rotated, the distal end 86 of the ejector lever 34 will contact the protrusion or blank 88 of the pawl 52, and the rotational force of the take-up lever 30 will be applied to the pawl 52 to move it to the open position. Fig.15 and Fig.16 The force applied to the pawl 52 by the ejector rod 34 can be used to break a frozen state in which the door secured by the vehicle latch 12 is frozen in a closed position. The distal end 86 of the ejector rod 34 can have a curved surface configured to engage the curved surface of the protrusion or blank 88.
[0050] In one non-limiting embodiment of the present disclosure, and to provide power assistance for opening the vehicle latch 12, actuation of the remote tightening actuator 14 occurs only when the pawl 54 is in the disengaged position and the pawl 52 is still in the primary or closed position (see at least Fig.14 and Fig.15 ). As a result, the remote tightening actuator 14 will be activated and the ejector rod 34 will contact the pawl 52 and push it from the main position to the open position. When the first switch determines that the pawl 54 is in the disengaged position and the second switch determines that the pawl 52 is still in the main position, activation of the remote tightening actuator 14 will occur. The first switch and the second switch are each operably connected to a controller, which is operably connected to the motor of the remote tightening actuator 14.
[0051] Thus, the remote tightening actuator 14 can perform two functions: 1) where the pawl 52 is tightened closed from the secondary position to the primary position, or 2) where the pawl is pushed open from the primary position. The type of activation applied by the remote tightening actuator 14 will be based on the position of the clutch lever 26, which corresponds to the position of the pawl 54.
[0052] Reference now Figure 2 and Figures 18 to 21 , showing an alternative embodiment of the present disclosure. Here, the vehicle latch 12 includes an electronic child lock feature. It should be understood that the vehicle latch 12 can be configured to have an electronic child lock feature in combination with a remote tightening actuator 14 with bypass and non-bypass operation to provide tightening and / or assisted opening, or the remote tightening actuator 14 with bypass and non-bypass operation to provide tightening and / or assisted opening can be unique to the vehicle latch 12. In other words, various embodiments of the present disclosure contemplate a vehicle latch 12 that only has a remote tightening actuator 14 with bypass and non-bypass operation to provide tightening and / or assisted opening, and does not have an electronic child lock feature.
[0053] like Figure 2 and Figures 18 to 21As shown, the motor 100 provides drive to a worm 102, which is operably coupled to a sector gear 104, which is pivotally mounted on an actuator housing 104 of the vehicle latch 12. The actuator housing 104 is fixed to the latch housing 20, or the actuator housing 104 and the latch housing 20 are formed together as a single component.
[0054] The child bypass lever or bypass lever 106 is pivotally mounted to the inside release lever 108. The inside release lever 108 is also pivotally mounted to the actuator housing 104. The child bypass lever 106 has an arm 110 that passes through an opening 112 in the inside release lever 108. The arm 110 is operably coupled to a child lock link 114, which is operably coupled to the other end of the sector gear 104. The arm 110 has a mid-piece portion 116 and a distal portion 118. The distal portion 118 engages the child lock link 114, and the mid-piece portion 116 engages a protrusion 120 of the power release lever 72.
[0055] Thus, when the child bypass lever 106 is in the first position (see Fig.18 ), and when the inside release lever 108 rotates in the direction of arrow 122, the intermediate portion 116 contacts the protrusion 120 of the power release lever 72, thereby causing the power release lever 72 to rotate in the direction of arrow 122, and then the pawl release lever 74 rotates the pawl lifter 80, which rotates the pawl 54. In other words, this movement opens the vehicle latch 12.
[0056] On the other hand, if the motor 100 is activated and the sector gear 104 is rotated, the child lock link 114 will move in the direction of arrow 124 and the child bypass lever 106 will rotate in the direction of arrow 122. This causes the arm 110 to move in the opening 112 so that the middle portion 116 of the arm 110 does not contact the protrusion 120 of the power release lever 72 when the inner release lever 108 rotates in the direction of arrow 122. See Figures 1 to 21 Thus, in this position, operation of the inside release lever 108 will not open the vehicle latch 12 .
[0057] Although the present disclosure has been described in detail with respect to only a limited number of embodiments, it should be readily understood that the present disclosure is not limited to such disclosed embodiments. Rather, the present disclosure may be modified to include any number of variations, alterations, substitutions, or equivalent arrangements that have not been described to date but are commensurate with the spirit and scope of the present invention. Furthermore, although various embodiments of the present disclosure have been described, it is to be understood that aspects of the present disclosure may include only some of the embodiments described. Therefore, the present disclosure should not be construed as being limited by the foregoing description, but only by the scope of the appended claims.
