    [0001] ASSEMBLY AND DOOR LATCHING SYSTEM BACKGROUND Embodiments of the present invention generally relate to locking devices and, more particularly, to locking devices for vehicles. Some known vehicles generally include movable panels such as doors, windows, a hood, a trunk lid, a tailgate and the like which are attached for articulated or sliding engagement with a vehicle body. Cooperating latch and latch systems are generally provided to ensure that these panels remain fixed in their fully closed position when the panel is closed. A locking device generally includes a fork bolt or fork that is pivoted between an unlocked position and a main locked position when the door is closed to lock the door in the closed position. The fork bolt is generally held in the main locked position by a lock lever or pawl that pivots between an engaged position and a disengaged position. The lock lever holds the fork bolt in the main locked position when in the engaged position and releases the fork bolt when in the disengaged position so that the door can be opened. The fork bolt is pivoted to the main locked position by a striker attached, for example, to an associated door post when the door is closed. Once in the main locked position, the lock lever engages the fork bolt to ensure that the assembly remains locked. In some known vehicles, the doors can be electrically closed automatically by a motor when the door is in a certain position, for example, a first safety position. Due to a large clearance during the transition to the locked closed position, a switch associated with the lock lever may not indicate when the door is closed. This can lead to engine operation in a locked position for an undesirable amount of time. Therefore, it is desirable to provide an improved locking assembly. SUMMARY OF THE INVENTION In a non-limiting embodiment, a locking assembly is proposed. The lock assembly includes a movable fork between a locked position and an unlocked position, and a movable pawl between a first position and a second position, the pawl engaging the fork and holding the fork in the locked position when the pawl is in the first position, the pawl disengaging from the fork for its movement to the unlocked position when the pawl is in the second position. The system also includes a ratchet elevation device operably associated with the ratchet, the ratchet elevation device being movable between an inactive switch position when the pawl is in the first position and an active switch position when the ratchet is in the second position, and a ratchet switch configured to generate a ratchet switch signal, the ratchet elevating device engaging the ratchet switch in an "active" condition when the ratchet elevating device is in the Active switch position, and the ratchet raising device disengages the ratchet switch in an "idle" condition when the ratchet lift device is in the inactive switch position.

DETAILED DESCRIPTION An example of a lock assembly which includes an integrated ratchet switch for use in detecting a true position of a vehicle door, such as an electric sliding door, is presented here. The ratchet switch is connected in parallel with a fork switch using existing electrical wiring so that the switches provide an electrical state of the lock device in different door positions. Referring now to the figures, an exemplary lock assembly 10 is illustrated in an open position (Fig. 1), an intermediate safety position (Fig. 2), and a closed position (Fig. 3). The lock assembly 10 can be integrated into a component of a vehicle, such as the door, the trunk, the frame surrounding the door opening or the trunk opening, or any other actuatable component of the vehicle , for example. The locking assembly 10 generally comprises a fork 12, a cooperating pawl 14, a switch cam 16, a ratchet raising device 18, a fork switch 20 and a pawl switch 22.
    [0004] The fork 12 is pivotally or rotatably mounted about a pin 56 which is received in an opening 24. The fork 12 is capable of rotating between an open or non-locked position shown in FIG. and a closed or locked position shown in Figure 3, on which the fork 12 rotates in the direction of the arrows 26.
    [0005] The lock assembly 10 is attached to a vehicle structure so that the fork 12 is moved between the open position (Figure 1) and the closed position (Figure 3) when a door, window, hatch, etc. is open and closed and the fork 12 engages with a striker (not shown) which is attached to the door, window, tailgate, etc. In the exemplary embodiment, the locking assembly 10 comprises a safety position (FIG. 2) which is an intermediate position between the open position and the closed position. In other embodiments, the lock assembly 10 is attached to the door, window, tailgate, etc., and the strike is attached to the vehicle body at an opening in which the door , the window, the tailgate, etc. is received. The cooperation of a fork and a strike is well known and should not be described in detail. The pawl 14 is pivotally mounted by a pin 28 received in a pin opening 30 formed in the pawl 14. The pawl 14 cooperates with the fork 12 in a well-known manner to hold the fork 12 in the safety position (Figure 2) and the closed position (Figure 3), or to release the fork 12 to return to the open position (Figure 1). That is, the pawl 14 pivots between a first released or disengaged position shown in Fig. 1 in the direction of the arrows 32, a second closed or engaged position shown in Fig. 2, and a third position. In the exemplary embodiment, the fork 12 is clockwise biased toward the open position shown in FIG. 1 or in the direction of the latch. arrow 34 by a biasing element (not shown, for example a helical or torsion spring or the like), one end of which is attached to the fork 12 and the other end is attached to a housing or other equivalent location. Likewise, a biasing member (not shown) urges pawl 14 in the direction of arrow 34A against one face of fork 12. In the exemplary embodiment, fork 12 has a surface 36 that slides along a surface 38 complementary to the pawl 14 when the fork 12 rotates from the open position (Figure 1) to the closed position (Figure 3). Once in the closed position (Fig. 3), a fork shoulder portion 40 engages a ratchet shoulder portion 42, thereby engaging fork 12 and securing it to the closed position when the striker is fixed in a receiving opening 44 of the fork 12. Once the locking assembly 10 is in the closed position, the pawl 14 is biased by spring in the direction of the arrow 34A and the shoulder 40 comes in engagement with the shoulder 42 so that the fork 12 can not rotate in the open position unless the pawl 14 is brought back to the release position (for example, by moving the shoulder 42 away from the shoulder 40 ) allowing the fork 12 to rotate in the direction of the arrow 34 in the open position.
    [0006] The fork 12 also includes a second shoulder portion 46 with which the ratchet shoulder portion 42 engages when the fork 12 has been engaged with the striker while the door is closed at the safety position ( Figure 2), at which point the door is still slightly ajar, with little or no compression of its seals (not shown), for example. Once in the safety position (FIG. 2), the second shoulder portion 46 of the fork engages the ratchet shoulder portion 42, thereby engaging the fork 12 and securing it to the fork first safety position. Once the locking assembly 10 is in the closed position, the pawl 14 is biased by spring in the direction of the arrow 34A and the shoulder 46 engages the shoulder 42 so that the fork 12 can not not turn in the open position unless the pawl 14 is returned to the release position (for example, by moving the shoulder 42 away from the shoulder 40), allowing the fork 12 to rotate in the direction of the arrow 34 in the open position. Further, in the exemplary embodiment, once the lock assembly 10 is in the first safety position, a controller 48 in communication with an electrical closure mechanism 49 (shown schematically) actuates the closure mechanism electrical 49 to pass the assembly 10 in the closed position (Figure 3). In the exemplary embodiment, the lock assembly 10 includes a ratchet sensing assembly 50 and a fork detecting assembly 52, which are in communication with the controller 48.
    [0007] The ratchet sensing assembly 50 includes a ratchet switch 22 and a ratchet elevating device 18, which facilitates the transition of the ratchet switch 22 between an "active" condition and an "inactive" condition for communication with the ratchet switch 22. The ratchet elevating device 18 is pivotally or rotatably mounted by a pin 28 received in a stud opening 30, and the pawl raising device 18 is rotatable with the pawl 14 during the rotation of the ratchet. Ratchet Lift Device 18. In the exemplary embodiment, the ratchet lift device 18 includes an engagement surface 54 configured to selectively engage with the ratchet switch 22. In the embodiment open position (Fig. 1), the engagement surface 54 does not contact the pawl switch 22 so that the pawl raising device 18 is in the switch position active. The engaging surface 54 is in contact with the pawl switch 22 when the fork 12 is in the safety position (Fig. 2) and in the closed position (Fig. 3) so that the pawl raising device 18 is in an inactive switch position. The fork detection assembly 52 includes a fork switch 20 and a switch cam 16, which facilitates the transition of the fork switch 20 between an "active" condition and an "inactive" condition for communication with the controller. The switch cam 16 is pivotally or rotatably mounted by a pin 56 received in a fork opening 24, and the switch cam 16 is rotatable with the fork 12 during rotation of the switch cam 16. In As an exemplary embodiment, the switch cam 16 includes a contact surface 58 configured to selectively engage the fork switch 20. In the open position (Fig. 1) and in the safety position (Fig. 2). ), the contact surface 58 is in contact with the fork switch 20 so that the switch cam 16 is in an active switch position. The contact surface 58 is not in contact with the fork switch 20 when the fork 12 is in the closed position (Fig. 3) so that the switch cam 16 is in an inactive switch position. In the exemplary embodiment, the fork switch 20 and the ratchet switch 22 are each micro-switches that provide a signal to the controller 48, as described herein in more detail. However, switches 20 and 22 may be any suitable switch or sensor that allows the assembly 10 to operate as described herein. The fork switch 20 is positioned to engage the switch cam 16 so that rotation of the fork 12 from the closed position to the safety position and / or to the open position causes the fork switch 20 move from an "inactive" position to an "active" position. Although described as "inactive" and "active" positions, the fork switch 20 may have any suitable position or condition that allows the system 10 to operate as described herein. In the "idle" position, the fork switch 20 sends a signal (or indicates a lack of a signal) to the controller 48 to indicate that the lock assembly 10 is in the closed position (Fig. 3). In the "on" position, the fork switch 20 sends a signal (or indicates a lack of a signal) to the controller 48 to indicate that the lock assembly 10 is in the safety position (Fig. 2) or the open position (Figure 1). In the exemplary embodiment, the pawl switch 22 is positioned to engage the pawl raising device 18 so that the pawl 14 is rotated from the first position (Fig. 1) to the second position. (Figure 2) or to the third position (Figure 3) causes the ratchet switch 22 to move from an "active" position to an "inactive" position. Although described as "inactive" and "active" positions, the ratchet switch 22 may have any appropriate position or condition that allows the system 10 to operate as described herein. In the "idle" position, the ratchet switch 22 sends a signal (or indicates a lack of a signal) to the controller 48 to indicate that the lock assembly 10 is in the first safety position (FIG. the closed position (Figure 3). In the "active" position, the ratchet switch 22 sends a signal (or indicates a lack of a signal) to the controller 48 to indicate that the lock assembly - 10 is in the open position (FIG. 1). As shown in FIG. 4, the lock assembly 10 includes an electrical circuit or latch connector 60 where the ratchet switch 22 is connected in parallel with the fork switch 20 so that only two wires A, B are necessary to communicatively couple switches 20 and 22 to controller 48. FIG. 5 illustrates another embodiment of lock connector 60 which includes a resistor 62 connected in series with fork switch 20, which facilitates the detection by the controller 48 that the locking assembly 10 is in the safety position (Figure 2). As such, a different voltage is present on the wire because of the resistor 62, which provides at least three different types of signals to the controller 48. For example, with reference to Figures 6 and 8, a signal 0 (zero) can indicate a lack of resistance, a signal 0.5 may indicate an intermediate resistance and a signal 1 may indicate a high resistance. The controller 48 can then transform these signals to determine the position or condition of the lock assembly 10. Referring to Figures 6-9, an exemplary operation of the lock assembly 10 is described herein. Figures 6 to 9 illustrate the correlations between the position of a vehicle door corresponding to the position of the lock assembly 10, the output signal from the fork switch 20, the output signal from the ratchet switch 22 and a result of the signals on the B wire of the lock connector 60. Figures 6 and 7 illustrate the correlations when the lock connector 60 does not include a resistor 62, and Figures 8 and 9 illustrate the correlations when locking device connector 60 includes a resistor 62. In the exemplary operation, fork 12 begins in an unlocked position (Fig. 1) corresponding to a component such as a vehicle door in an open position . The switch cam 16 is oriented in the active switch position so that the contact surface 58 of the switch cam is in contact with the fork switch 20 in the "active" state where the fork switch 20 sends a signal to the controller 48 indicating that the vehicle door is in the open / security position. The pawl 14 is in the first position and the pawl raising device 18 is oriented in the active switch position so that the engagement surface 54 of the pawl raising device is not in contact with the pawl raising device. Pawl switch 22. As such, the pawl switch 22 is in the "active" state where the pawl switch 22 sends a signal to the controller 48 which indicates that the vehicle door is in the open position. Therefore, the switches 20, 22 indicate to the controller 48 that the vehicle door is open.
    [0008] As the vehicle door moves from the open position (FIG. 1) to the safety position (FIG. 2), the fork 12 rotates counterclockwise and the pawl 14 rotates from the first position (FIG. 1) where it is disengaged from the fork 12 to the second position (FIG. 2) where the pawl shoulder 42 is engaged with the fork shoulder 40 to prevent accidental movement of the vehicle door to the position opened. As such, the contact surface 58 remains in contact with the fork switch 20, and the pawl 14 has rotated clockwise, causing the engaging surface 54 to contact the switch. pawl 22, thereby causing switch 22 to enter the "idle" condition. As such, the fork switch 20 sends a signal to the controller 48 indicating that the vehicle door is in the open or safety position, and the ratchet switch 22 sends a signal to the controller 48 which indicates that the vehicle door is in the safety position or closed. The controller 48 may subsequently actuate the motor of the electric closing mechanism 49 to initiate an electrical closing operation where the fork 12 is rotated counterclockwise in the locked position (FIG. 3) to secure safe way the door in a closed position. As the vehicle door moves from the safety position (Fig. 2) to the closed position (Fig. 3), the fork 12 rotates to the locked position and the pawl 14 rotates to the third position (Fig. 3). Therefore, in the closed door position, the engaging surface 54 remains in contact with the pawl switch 22, and the switch cam 16 has been turned out of engagement with the fork switch 20, making this switch switch 20 to the "idle" condition. As such, the fork switch 20 sends a signal to the controller 48 which indicates that the vehicle door is in the closed position. The controller 48 can then stop the electrical closing operation and stop the motor of the electrical closing mechanism. As the vehicle door returns to the open position (Fig. 1), the pawl 14 disengages from the fork 12, and the fork 12 rotates clockwise from the locked position (Fig. the unlocked position (Figure 1). As such, the contact surface 58 engages the fork switch 20 indicating to the controller 48 an open or safety door position, and the ratchet elevating device 18 rotates out of engagement with the ratchet switch. 22, indicating to the controller 48 an open door position. Operation of the lock assembly 10 can then be repeated as the door moves back from the open position (Fig. 1) to the safe position (Fig. 2), and to the closed position (Fig. 3). A lock assembly for detecting a position of a vehicle door is described herein. The lock assembly includes a fork switch and a ratchet switch connected in parallel. Economically, the fork switch and the ratchet switch can be coupled in parallel using only two wires. The switches are communicatively coupled to a controller (e.g., vehicle electronics) and parts of the lock assembly selectively engage therewith to indicate various positions of the vehicle door as the switches are in an "active / inactive" condition. In addition, a resistor can be coupled in series with the fork switch. Therefore, the two switches provide a better indication of the position of a door, and thus, better door operation, greater security of door closure and greater safety of the occupants of a vehicle.
    [0009] Although the invention has been described with reference to an exemplary embodiment, those skilled in the art will understand that various changes may be made and that equivalents may be substituted for the elements thereof without departing from the scope of the invention. In addition, many modifications can be made to adapt a particular situation or material to the teachings of the invention without departing from the essential extent thereof. Therefore, it is intended that the invention is not limited to the particular embodiment presented as the best mode contemplated for carrying out the present invention.
