Patent Application
20230358088
This application claims priority under 35 U.S.C. § 119 to the following Indian Patent Application No. 202211026107, filed on May 5, 2022, the entire contents of which are incorporated herein by reference thereto.
Exemplary embodiments of the present disclosure pertain to the art of vehicle windows and in particular window systems.
Window systems are adjusted for glass sealing by adjusting the regulator rails by means of slotted brackets or Jack screws.
However, this method can limit the stiffness of the system, is costly in tools and components, and can adversely affect the glass system deflection. In addition and when the adjustment is performed on the rail, additional clearances are needed in the door for rail packaging.
Disclosed is an apparatus for adjusting a location of a rail of a window regulator with respect to a vehicle door panel, the apparatus including: a jack-screw secured to a gear, the gear and the jack-screw being rotatably secured to the vehicle door panel; a worm rotatably secured to the vehicle door panel, the worm being configured to meshingly engage the gear; and a nut secured to the rail, the jack-screw threadingly engaging the nut, wherein when the worm is rotated the jack-screw will rotate in either a clockwise or counter clockwise direction which will cause the rail to move in a direction with respect to the vehicle door panel.
In addition to one or more of the features described above, the worm is accessible from outside of a vehicle door.
In addition to one or more of the features described above, the apparatus is located in a lower area of the rail.
In addition to one or more of the features described above, the vehicle door panel provides a guiding for a tool that is configured to engage a head of the worm in order to provide a rotational force to the worm.
In addition to one or more of the features described above, the apparatus is located in a lower area of the rail.
In addition to one or more of the features described above, the vehicle door panel provides a guiding for a tool that is configured to engage a head of the worm in order to provide a rotational force to the worm.
Also disclosed is a method for adjusting a location of a rail of a window regulator with respect to a vehicle door panel, including: rotatably securing a jack-screw and a gear to the vehicle door panel, the jack-screw being fixed to the gear; rotatably mounting a worm to the vehicle door panel, the worm being configured to meshingly engage the gear; and securing a nut to the rail, the jack-screw threadingly engaging the nut, wherein when the worm is rotated the jack-screw will rotate in either a clockwise or counter clockwise direction which will cause the rail to move in a direction with respect to the vehicle door panel.
In addition to one or more of the features described above, the worm is accessible from outside of a vehicle door.
In addition to one or more of the features described above, the gear and the worm are located in a lower area of the rail.
In addition to one or more of the features described above, the vehicle door panel provides a guiding for a tool that is configured to engage a head of the worm in order to provide a rotational force to the worm.
In addition to one or more of the features described above, the gear and the worm are located in a lower area of the rail.
In addition to one or more of the features described above, the gear and the worm are located in a lower area of the rail.
In addition to one or more of the features described above, the vehicle door panel provides a guiding for a tool that is configured to engage a head of the worm in order to provide a rotational force to the worm.
The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
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 an apparatus for adjusting the position of a rail of a window regulator with respect to a vehicle door panel.
In one embodiment, the window regulator is contemplated for use in a frameless door assembly for an automotive vehicle wherein the window has no frame surrounding its top and upper side portions of its sides when the window is in the closed position. As such, a window regulator for a frameless door assembly must provide window stability in all directions and effectuate movement of the window to and from its associated exterior seal on the vehicle as the window approaches and leaves its closed position.
The apparatus 14 and gear set up will allow for tuning of the rail 16 in the Y directed from outside of the vehicle door by rotating the worm in any direction between the Z and X directions illustrated in
The gear drive setup is self-locking due to worm/gear connection. The worm 28 can be driven by a Hexagon, Torx or Imbus tool with an appropriate length which turns the worm 28 which drives the gear 26. As mentioned above, the gear 26 will turn the jack-screw 24 which then moves the nut 30 in the Y-direction which is fixed to the rail 16. As such, rotation of the worm 28 causes adjustment of the rail 16 in the Y direction.
As illustrated, the apparatus 14 is located in a lower area (illustrated by the dashed lines in
In one non-limiting embodiment, the vehicle door panel 10 can provide guiding 32 for a tool 34 (illustrated by the dashed lines in
In one non-limiting embodiment, the vehicle door will have a hole aligned with the worm such that an individual will be able to do fine tune the location of the rail 16 by just removing a cover on the hole in the vehicle door without the need to disassemble the vehicle door trim.
The term “about” is intended to include the degree of error associated with measurement of the particular quantity based upon the equipment available at the time of filing the application. For example, “about” can include a range of ±8% or 5%, or 2% of a given value.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, element components, and/or groups thereof.
While the present disclosure has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the present disclosure without departing from the essential scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this present disclosure, but that the present disclosure will include all embodiments falling within the scope of the claims.
