A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
The present disclosure is directed to a cursor with four main elements: a cursor body that is configured to slide along a rail; a pivoting plate or swing plate with a threaded adjuster; a clamping plate; and an isolator which is captured in the assembly by a clamp screw which is partially installed into the sub assembly for ease of assembly at the original equipment manufacturer (OEM).
Referring now to the FIGS. and in particular the FIGS., a pivoting cursor 10 for use with a window regulator 12 of a vehicle door module 14 in accordance with various embodiments of the present disclosure is illustrated. Referring now to the embodiment illustrated in at least
In one embodiment, the pivoting plate or swing plate 18 is rotationally or pivotally mounted to the pivot pin 19 or a shaft, rod or elongated member 19. The pivot pin 19 is secured to a connecting member 21 that is secured to the main body portion 16 via a second adjusting screw 23 or second threaded adjuster 23. The second adjusting screw 23 or second threaded adjuster 23 threadingly engages the connecting member 21 for adjusting the location of the main body portion 16 with regard to the connecting member 21. The second adjusting screw 23 or second threaded adjuster 23 has a flange 25 for engaging the main body portion 16 and a locking nut 27 for maintaining the second adjusting screw or second threaded adjuster 23 in a desired position once the cursor 10 has been adjusted via rotational movement of the second adjusting screw or second threaded adjuster 23.
In one embodiment, the first adjusting screw or first threaded adjuster 26 includes a first threaded portion 30 for threadingly engaging a threaded opening 32 of the cursor body 16. In addition, the first adjusting screw or first threaded adjuster 26 also includes a flange portion 34 that is larger than an opening 36 in the clamping plate or glass clamping plate 22. The first adjusting screw or first threaded adjuster 26 also includes a second threaded portion 28 that threadingly engages threads 40 of the locking nut 28.
A portion of a vehicle window 42 is located between the pivoting plate or swing plate 18 and the glass clamp plate 22. A seal or isolator 24 is located between the window 42 and the pivoting plate or swing plate 18 and the glass clamp plate 22. In order to secure the window 42 to the pivoting cursor 10, a glass clamp screw threadingly engages a threaded opening in the pivoting plate or swing plate 18.
Once the pivoting plate or swing plate 18 is secured to the main body portion 16 via the first adjusting screw or first threaded adjuster 26 engaging threaded opening 32, rotation of the first adjusting screw or first threaded adjuster 26 about axis 54 will cause the pivoting plate or swing plate 18 and glass clamp plate 22 to move in the directions of arrows 56 along axis 54. This movement will cause the pivoting plate or swing plate 18 to pivot about axis 20 about pivot pin 19, which will in turn cause movement of the window 42 in order to provide an adjustment in the Y-direction when installing the window 42 in a vehicle. This is particularly useful in a frameless door window design. In addition and by configuring the cursor 10 such that the first adjusting screw or first threaded adjuster 26 can be rotated by a tool from an inboard side of the vehicle allows for convenient access when the vehicle window 42 is being installed in a vehicle.
Still further, further adjustment may be provide by rotating the second adjusting screw or second threaded adjuster 23. Rotation of the second adjusting screw or second threaded adjuster 23 about axis 29 will cause the cursor body 16 to move in the directions of arrows 31 along axis 29.

In one non-limiting embodiment, a window regulator 12 for a front door assembly only uses the pivoting cursor 10 for the rear portion of the window 42 while a separate non-pivoting cursor is used for the forward portion of the window 42 each being slidably secured to a respective one of the guide rails 70. In another non-limiting embodiment, the window regulator 12 for the front door assembly uses a pivoting cursor 10 for both the rear portion of the window 42 and the forward portion of the window 42 each being slidably secured to a respective one of the guide rails 70. In yet another non-limiting embodiment, the window regulator 12 used with a rear door assembly employs the pivoting cursor 10 for both the forward portion of the window 42 and the rear portion of the window 42, each being slidably secured to a respective one of the guide rails 70. Still further and in yet another alternative embodiment, the window regulator for a rear door assembly may use a pivoting cursor for only the rear portion of the window 42 and a separate non-pivoting cursor for the forward portion of the window 42 each being slidably secured to a respective one of the guide rails 70. In yet another alternative and in either the front door assembly or the rear door assembly the pivoting cursor may be used for the forward portion of the window 42 and a non-pivoting cursor may be used for the rear portion of the window each being slidably secured to a respective one of the guide rails 70.
The pivoting cursors 10 are adjustable from an inboard side of the vehicle with or without the door closed. The first adjusting screw or first threaded adjuster 26 and the second adjusting screw or second threaded adjuster 23 may be rotated to adjust the location of the pivoting cursor 10 and accordingly window 42. Once the adjustment corresponding to the precise and actual geometry of the vehicle which variates due to construction tolerances, the first adjusting screw or first threaded adjuster 26 is held in position by a first tool inserted into opening 72 while the locking nut 28 is tightened with a second tool such that position of the pivoting plate or swing plate 18 with respect to the main body portion 16 is maintained and any further rotation of the first adjusting screw or first threaded adjuster 26 is prevented. In addition and once the desired positioned position of the second adjusting screw or second threaded adjuster 23 is provided, the second adjusting screw or second threaded adjuster 23 is held in position by a first tool inserted into opening 73 while the locking nut 27 is tightened with a second tool such that position of the main body portion 16 defined with respect to the connecting member 21 and any further rotation of the second adjusting screw or second threaded adjuster 26 is prevented.
In one alternative embodiment, the guide rail 70 is a hollow tube or structure formed from a metal such as aluminum, steel, metallic alloys or the hollow tube formed from a plastic material, or a plastic composite material. Still further and in one nonlimiting embodiment, the main body portion 16 of the pivoting cursor 10 or a portion thereof is configured to completely surround a periphery of the guide rail 70. As such, the portion of the main body portion 16 of the pivoting cursor 10 surrounding the guide rail 70 will have multiple contact points with the guide rail in order to prevent twisting of the pivoting cursor as it slides up and down the guide rail 70.
In one non-limiting embodiment, the main body portion 16 of the pivoting cursor 10 is formed from an easily molded material such as plastic of nylon and the main body portion 16 is configured to have a have an insert or inserts 80 such as a polyoxymethylene (POM) insert that defines an opening for the guide rail 70 to slide therethrough.
