Definitions
- the present invention relates to a slider window assembly for a vehicle and, more particularly, a rear slider window assembly for a pickup truck or the like.
- slider window assembly for an opening of a vehicle, such as a rear slider window assembly for a rear opening of a pickup truck.
- Conventional slider window assemblies for rear openings of trucks or the like typically include three or more panels, such as two fixed window panels and a slidable window panel.
- the slidable window panel is supported by rails and may be moved along the rails to open and close the window.
- the present invention provides a rear slider window assembly having a drive system that uses a single flexible drive element to open and close the window.
- the window assembly and drive system include structure that limits flexing or bending of the drive element when pulling or pushing the movable window.
- the rear slider window assembly includes a frame portion having an upper rail and a lower rail, a fixed window panel (defining an opening) that is fixed relative to said frame portion, and a movable window panel that is movable along the upper rail and the lower rail.
- the movable window panel is movable between a closed position, where the movable window panel is disposed at the opening, and an opened position, where the movable window panel is disposed at least partially along the at least one fixed window panel.
- a drive system is operable to move the movable window panel between the opened and closed positions.
- the drive system comprises a single flexible drive element that, when the drive system is actuated to move the window panel in one direction, pulls the movable window panel along the lower rail, and when the drive system is actuated to move the window panel in the opposite direction, the drive element pushes the movable window panel along the lower rail.
- the lower rail of the frame portion comprises guide structure that limits flexing or bending of the drive element when the drive element pushes the movable window panel along the lower rail.
- the flexible drive element may comprise a flexible cable or tape, and the guide structure may comprise one or more channels disposed along or formed along the lower rail or a telescoping support or the like.
- rotatably driving the drive motor of the drive system in one direction causes movement of the flexible drive element in one direction to open the window
- rotatably driving the drive motor of the drive system in the opposite direction causes movement of the flexible drive element in the opposite direction to close the window.

- a rear slider window assembly 10 of a vehicle 12 (such as a pickup truck or the like) includes a window frame 14 , a fixed window panel 15 having an aperture that separates side window portions 16 , 18 and a movable window panel 20 that is movable relative to frame 14 and fixed window panel between an opened position and a closed position ( FIGS. 1-3 ).
- the movable window panel 20 is movable along the frame 14 (such as along upper and lower rails or channels of the frame) relative to the fixed window panel(s) via a drive system that pulls and/or pushes the movable panel in either direction to open and close the rear window, such as responsive to a user input or switch in the vehicle cabin.
- the drive system comprises a single flexible drive element, such as a flexible cable or tape or extending/retracting element that is disposed along the channel only on one side of the opening.
- the drive system does not have two cables that function to pull at the movable window panel in either direction to open or close the window. Instead, the drive system pulls the movable window in one direction and pushes it in the other direction to open and close the window.
- the window assembly and drive system include guide structure that limits or precludes flexing or bending of the flexible drive element as it moves along the lower rail of the window, particularly when pushing the movable window panel along the lower rail.
- the drive system comprises a drive motor 24 of a flexible helical cable drive system 26 ( FIGS.
- the drive systems and window panels and channels/frames may be similar construction across several or all of the window assemblies, such that detailed discussions of common or similar aspects may not be repeated throughout the disclosure.
- the drive system is mounted at the end of the lower channel or frame or rail 14 a , which comprises a plastic U-shaped channel portion 14 b (adhered to the interior surface of the fixed window panel) and an aluminum extruded channel 14 c , along which the movable window panel 20 and its carrier 20 a slidably move when opened and closed.
- the end of the lower rail 14 a at which the drive system is attached or mounted includes an end cap 14 d , which may be formed to accommodate or guide or support the cable or tape or tube of the drive system, as discussed below.
- the drive motor or actuator or housing of the drive system may be pivotally mounted at the lower corner of the fixed window panel, so that the drive motor and cable or tape may be flipped onto the interior surface of the window for packaging and transport of the window assembly.
- the motor is flipped down and affixed relative to the window (via attachment at a window mounting bracket and/or at a vehicle mounting bracket) in its use position (shown in the drawings).
- Such a pivotable attachment reduces the size of the window assembly during transport.
- the drive motor 24 of drive system 26 rotatably drives a gear that engages the flexible drive element or helical cable 26 a to move the cable in either direction along the lower rail or channel 14 a to move the movable window panel 20 relative to the frame 14 and fixed panel 15 .
- the helical cable 26 a is routed from the drive motor 24 through a rigid cable tubing 26 b and into a receiving portion 26 c of the end cap attachment 14 d .
- the end of the cable 26 a attaches at a carrier attachment 26 d of the carrier 20 a of the movable window panel.
- the cable 26 a is routed along an extruded channel or passageway 26 e of the rail 14 a such that the cable 26 a does not bend or flex along the rail 14 a when the drive system is moving the movable window panel away from the drive motor to close the window.
- the drive motor 24 rotates the gear that engages the cable 26 a to move the cable in either direction through the rigid tubing 26 b and rail or channel 14 a , which moves the carrier and movable window panel 20 along the frame 14 .
- the drive motor 24 of the drive system 28 rotatably drives a reel that coils and uncoils a flexible cable 28 a .
- the cable 28 a includes notches along a side thereof for engaging teeth of the motor drive or reel 28 b to impart winding or unwinding of the cable 28 a from the reel.
- the cable is routed through a guide tube 28 c that connects between the reel and motor and the end of the rail or channel 14 a . The cable is further routed into a passageway of the end cap of the rail ( FIG.
- a connector or pin or element that is configured to connect the cable to the carrier of the movable window panel.
- the cable is connected to the connector/end of the carrier via a pin 28 e ( FIG. 15 ) that extends upward from the end of the cable and through a slot 28 f along the top of the passageway (see FIG. 21 ).
- the pin moves with the cable end and moves along the slot formed along the top of the passageway.
- the rail and extruded cable enclosure thus function to guide the cable and to limit or preclude flexing of the cable, which is flexible but sufficiently strong so as to be able to push the carrier and movable panel when the cable is unwound from the reel.
- the drive motor 24 of the drive system 30 rotatably drives a reel that coils and uncoils a flexible tape or strip 30 a (such as a flattened metallic strip that is flexible in one direction and not as flexible in another direction orthogonal to the one direction) via rotation of a reel 30 b ( FIG. 29 ).
- the reel 30 b has a toothed outer circumferential surface for engaging a drive gear of the motor, such that rotation of the drive gear rotates the reel about an axis normal to the axis of rotation of the drive gear.
- the tape 30 a comprises a generally U-shaped tape that allows for limited flexing of the tape.
- the tape 30 a is received and moves along a correspondingly formed or similarly formed passageway 30 c of the rail or channel 14 a , where the passageway 30 c limits flexing of the tape so that the tape is capable of pushing the carrier and movable panel along the frame and fixed window panel when the drive motor is actuated to uncoil the flexible tape from the reel.
- the tape 30 a is received through a passageway or guide portion 30 d of the channel 14 b ( FIG. 32 ) and then is received in the passageway 30 c of the extruded channel 14 c ( FIG.
- the end of the tape 30 a may connect to the carrier of the movable window panel via any suitable connection, such as a pin or connector that extends upward through a slot at the upper region of the passageway 30 c (such as in a similar manner as the pin 28 e moves along the slot 28 f for drive system 28 ).
- the drive motor 24 of the drive system 32 rotatably drives a drive gear 32 b that rotates a toothed wheel or gear 32 c that engages and moves a flexible notched tape 32 a .
- the toothed wheel or gear 32 c is disposed within the lower rail and is rotatable about a vertical axis and engages notches of the flexible notched tape 32 a , such that rotation of the drive gear and toothed wheel moves the tape 32 a around the toothed wheel in either direction.
- the motor 24 may rotatably drive the drive gear 32 b via an output drive gear that rotates about a horizontal axis, such as can be seen with reference to FIGS. 46 and 47 .
- the drive gearbox and gear 32 b and toothed wheel 32 c and the notched tape are disposed within the rail or within the profile of the rail and thus may be packaged within the rail for a reduced profile drive system.
- the notched tape 32 a is routed along channels 32 d , 32 e along opposite sides of the rail or channel 14 a ( FIG. 42 ).
- the channel 32 d is formed or extruded along the aluminum rail 14 c that is received in the molded lower rail or channel 14 b
- the channel 32 e is formed along the surface of the lower rail or channel 14 b that faces toward and is bonded to the interior surface of the fixed window panel 15 .
- One end of the notched tape 32 a (such as the end of the portion of the tape that is in channel 32 d ) is connected to or attached to the carrier 32 f of the movable window panel (such as via a pin or tooth or pins or teeth being received in notches at the end of the tape), such that movement of the tape (via rotation of the toothed wheel 32 c ) moves the end of the tape and the movable window panel along the frame and fixed window panel.
- the other end or portion of the tape (see FIGS. 46 and 47 ) is disposed in and moves along the channel 32 e of the lower rail or channel 14 b , which functions to guide and support the tape during operation of the drive system 32 .
- the channels 32 d , 32 e function to allow for movement of the tape in either direction but limit or preclude flexing of the tape so that the tape can function to push the carrier and movable window panel along the frame.
- the end of the tape attached to the carrier moves along the channel 32 d and pulls at the carrier and movable window to open the window, with the other end of the tape moving along channel 32 e away from the toothed wheel.
- the toothed wheel is rotated in the clockwise direction in FIG. 43
- the end of the tape attached to the carrier moves along the channel 32 d and pushes at the carrier and movable window to close the window, with the other end of the tape moving along the channel 32 e toward the toothed wheel.
- the drive motor 24 of drive system 34 winds and unwinds a flexible cable 34 a about a spool or reel 34 b .
- the cable 34 a is received in or disposed in a telescoping support tube or enclosure or construction 34 c that telescopingly extends when the cable is uncoiled or unwound and telescopingly retracts when the cable is coiled or wound.
- the cable is a flexible cable to allow for coiling at the reel or spool, yet is sufficiently resistant to flexing (when restrained by the tube) as it is extended and pushes the innermost section of the telescoping support tube outward.
- the telescoping tube support 34 c comprises three sections (a base section that receives a middle or intermediate section that receives an innermost section).
- the telescoping support tube 34 c is disposed along the channel or rail 14 a and, when extended, the end of the innermost section of the support tube reaches to around the mid-point of the window assembly (see FIGS. 50 and 51 ).
- the movable window panel can be fully opened, whereby the middle of the movable window panel and the end of the innermost tube section approaches and is at or near the end of the base section of the tube.
- the base section may be smaller in length (and the tube may comprise four or five sections) to provide clearance at the base end between the carrier and end of the rail for the telescoping tube (when it is retracted).
- the telescoping tube is received in or at an end cap attachment 34 d , which guides and supports at least the base of the tube along the rail or channel 14 a .
- the base portion of the tube may be further supported via formed (extruded or molded) receiving portions along the rail or channel, and additional supports may be formed along the rail or channel to guide and/or support the extended portions of the telescoping tube when the tube is at least partially extended.
- the drive systems of the present invention provide for opening and closing the rear slider window assembly via a single flexible drive element or cable or tape or strip or the like that pulls the movable window panel in one direction (such as to open the window) and pushes the movable window panel in the other direction (such as to close the window).
- the drive systems include guides or structure that guide and support the flexible cable/tape to limit flexing or bending of the flexible cable/tape along the lower rail, particularly when the drive system is extending or uncoiling the flexible cable/tape to push the movable window panel along the frame.
- the drive motor assembly and rail configurations may utilize aspects of the drive assemblies of the types described in U.S. Pat. Nos. 4,920,698; 4,995,195; 5,146,712; 5,531,046; 5,572,376; 6,955,009; 7,073,293; 8,151,519 and/or 8,938,914, and/or U.S. Publication Nos. US-2017-0356231; US-2004-0020131 and/or US-2008-0127563, which are all hereby incorporated herein by reference in their entireties.
- the window assembly comprises a hole-in-glass window configuration, where a single fixed glass panel has an aperture or hole or opening established therethrough to define separate spaced apart fixed window panels or panel portions, such as in a similar manner as the window assemblies described in U.S. Pat. No. 8,881,458, which is hereby incorporated herein by reference in its entirety.
- the window assembly may include two fixed window panels that are spaced apart so as to define an opening therebetween.
- the fixed window panels may comprise two separate spaced apart fixed window panels that define the opening therebetween (and with upper and lower appliqués or trim or filler panels or elements disposed at the upper and lower regions of the opening and between the fixed window panels, and thus with the lighting device disposed behind the upper appliqué or the like).
- vehicular movable window assemblies other than a rear slider window assembly for a pickup truck or the like, such as (for example) a slider window assembly suitable for use as a movable side window for a vehicle such as a van or a bus.

Conventional slider window assemblies for rear openings of trucks or the like typically include three or more panels, such as two fixed window panels and a slidable window panel. The slidable window panel is supported by rails and may be moved along the rails to open and close the window.
- The present invention provides a rear slider window assembly having a drive system that uses a single flexible drive element to open and close the window. The window assembly and drive system include structure that limits flexing or bending of the drive element when pulling or pushing the movable window.
- According to an aspect of the present invention, the rear slider window assembly includes a frame portion having an upper rail and a lower rail, a fixed window panel (defining an opening) that is fixed relative to said frame portion, and a movable window panel that is movable along the upper rail and the lower rail. The movable window panel is movable between a closed position, where the movable window panel is disposed at the opening, and an opened position, where the movable window panel is disposed at least partially along the at least one fixed window panel. A drive system is operable to move the movable window panel between the opened and closed positions. The drive system comprises a single flexible drive element that, when the drive system is actuated to move the window panel in one direction, pulls the movable window panel along the lower rail, and when the drive system is actuated to move the window panel in the opposite direction, the drive element pushes the movable window panel along the lower rail. The lower rail of the frame portion comprises guide structure that limits flexing or bending of the drive element when the drive element pushes the movable window panel along the lower rail.
- The flexible drive element may comprise a flexible cable or tape, and the guide structure may comprise one or more channels disposed along or formed along the lower rail or a telescoping support or the like. Thus, rotatably driving the drive motor of the drive system in one direction causes movement of the flexible drive element in one direction to open the window, and rotatably driving the drive motor of the drive system in the opposite direction causes movement of the flexible drive element in the opposite direction to close the window. The flexible drive element may be coiled or spooled when retracted, or may be routed along another side region of the lower rail (so that the entirety of the flexible drive element is disposed along the rail).

slider window assembly 10 of a vehicle 12 (such as a pickup truck or the like) includes awindow frame 14, a fixedwindow panel 15 having an aperture that separatesside window portions movable window panel 20 that is movable relative to frame 14 and fixed window panel between an opened position and a closed position (FIGS. 1-3 ). Themovable window panel 20 is movable along the frame 14 (such as along upper and lower rails or channels of the frame) relative to the fixed window panel(s) via a drive system that pulls and/or pushes the movable panel in either direction to open and close the rear window, such as responsive to a user input or switch in the vehicle cabin. - The drive system comprises a single flexible drive element, such as a flexible cable or tape or extending/retracting element that is disposed along the channel only on one side of the opening. In other words, the drive system does not have two cables that function to pull at the movable window panel in either direction to open or close the window. Instead, the drive system pulls the movable window in one direction and pushes it in the other direction to open and close the window. The window assembly and drive system include guide structure that limits or precludes flexing or bending of the flexible drive element as it moves along the lower rail of the window, particularly when pushing the movable window panel along the lower rail. The drive system comprises a
drive motor 24 of a flexible helical cable drive system 26 (FIGS. 2-12 ) or a flexible cable drive system 28 (FIGS. 13-24 ) or a flexible tape drive system 30 (FIGS. 25-34 ) or a flexible notched tape drive system 32 (FIGS. 35-48 ) or a telescoping cable drive system 34 (FIGS. 49-58 ), as discussed below. The drive systems and window panels and channels/frames may be similar construction across several or all of the window assemblies, such that detailed discussions of common or similar aspects may not be repeated throughout the disclosure. - The drive system is mounted at the end of the lower channel or frame or rail 14 a, which comprises a plastic
U-shaped channel portion 14 b (adhered to the interior surface of the fixed window panel) and an aluminum extrudedchannel 14 c, along which themovable window panel 20 and itscarrier 20 a slidably move when opened and closed. The end of thelower rail 14 a at which the drive system is attached or mounted includes anend cap 14 d, which may be formed to accommodate or guide or support the cable or tape or tube of the drive system, as discussed below. - Optionally, and desirably, the drive motor or actuator or housing of the drive system may be pivotally mounted at the lower corner of the fixed window panel, so that the drive motor and cable or tape may be flipped onto the interior surface of the window for packaging and transport of the window assembly. When the window assembly is to be installed in the vehicle, the motor is flipped down and affixed relative to the window (via attachment at a window mounting bracket and/or at a vehicle mounting bracket) in its use position (shown in the drawings). Such a pivotable attachment reduces the size of the window assembly during transport.
- Referring to
FIGS. 2-12 , thedrive motor 24 ofdrive system 26 rotatably drives a gear that engages the flexible drive element orhelical cable 26 a to move the cable in either direction along the lower rail orchannel 14 a to move themovable window panel 20 relative to theframe 14 and fixedpanel 15. As shown inFIGS. 6 and 7 , thehelical cable 26 a is routed from thedrive motor 24 through arigid cable tubing 26 b and into a receivingportion 26 c of theend cap attachment 14 d. The end of thecable 26 a attaches at acarrier attachment 26 d of thecarrier 20 a of the movable window panel. - The
cable 26 a is routed along an extruded channel orpassageway 26 e of therail 14 a such that thecable 26 a does not bend or flex along therail 14 a when the drive system is moving the movable window panel away from the drive motor to close the window. Thus, during operation of thedrive system 26, thedrive motor 24 rotates the gear that engages thecable 26 a to move the cable in either direction through therigid tubing 26 b and rail orchannel 14 a, which moves the carrier andmovable window panel 20 along theframe 14. - Referring now to
FIGS. 13-24 , thedrive motor 24 of thedrive system 28 rotatably drives a reel that coils and uncoils aflexible cable 28 a. As shown inFIG. 19 , thecable 28 a includes notches along a side thereof for engaging teeth of the motor drive or reel 28 b to impart winding or unwinding of thecable 28 a from the reel. As shown inFIG. 23 , the cable is routed through aguide tube 28 c that connects between the reel and motor and the end of the rail orchannel 14 a. The cable is further routed into a passageway of the end cap of the rail (FIG. 23 ) and along apassageway 28 d formed with therail 14 a (such as extruded with the aluminum rail or channel, as can be seen inFIG. 21 ), with the passageway along the rail receiving the cable therein and having side walls or structure that limits or precludes any flexing of the cable so that the cable can function to push the movable panel along the frame and fixed window panel. - At the end of the cable is a connector or pin or element that is configured to connect the cable to the carrier of the movable window panel. In the illustrated embodiment, the cable is connected to the connector/end of the carrier via a
pin 28 e (FIG. 15 ) that extends upward from the end of the cable and through aslot 28 f along the top of the passageway (seeFIG. 21 ). When the cable is wound and unwound at thereel 28 b by the drive motor, the pin moves with the cable end and moves along the slot formed along the top of the passageway. The rail and extruded cable enclosure thus function to guide the cable and to limit or preclude flexing of the cable, which is flexible but sufficiently strong so as to be able to push the carrier and movable panel when the cable is unwound from the reel. - Referring now to
FIGS. 25-34 , thedrive motor 24 of thedrive system 30 rotatably drives a reel that coils and uncoils a flexible tape or strip 30 a (such as a flattened metallic strip that is flexible in one direction and not as flexible in another direction orthogonal to the one direction) via rotation of areel 30 b (FIG. 29 ). As shown inFIGS. 32 and 33 , thereel 30 b has a toothed outer circumferential surface for engaging a drive gear of the motor, such that rotation of the drive gear rotates the reel about an axis normal to the axis of rotation of the drive gear. - As shown in
FIG. 31 , thetape 30 a comprises a generally U-shaped tape that allows for limited flexing of the tape. Thetape 30 a is received and moves along a correspondingly formed or similarly formedpassageway 30 c of the rail orchannel 14 a, where thepassageway 30 c limits flexing of the tape so that the tape is capable of pushing the carrier and movable panel along the frame and fixed window panel when the drive motor is actuated to uncoil the flexible tape from the reel. As can be seen with reference toFIGS. 32 and 33 , thetape 30 a is received through a passageway or guideportion 30 d of thechannel 14 b (FIG. 32 ) and then is received in thepassageway 30 c of the extrudedchannel 14 c (FIG. 33 ). The end of thetape 30 a may connect to the carrier of the movable window panel via any suitable connection, such as a pin or connector that extends upward through a slot at the upper region of thepassageway 30 c (such as in a similar manner as thepin 28 e moves along theslot 28 f for drive system 28). - Referring now to
FIGS. 35-48 , thedrive motor 24 of thedrive system 32 rotatably drives adrive gear 32 b that rotates a toothed wheel orgear 32 c that engages and moves a flexible notchedtape 32 a. As shown inFIGS. 43 and 44 , the toothed wheel orgear 32 c is disposed within the lower rail and is rotatable about a vertical axis and engages notches of the flexible notchedtape 32 a, such that rotation of the drive gear and toothed wheel moves thetape 32 a around the toothed wheel in either direction. Themotor 24 may rotatably drive thedrive gear 32 b via an output drive gear that rotates about a horizontal axis, such as can be seen with reference toFIGS. 46 and 47 . The drive gearbox andgear 32 b andtoothed wheel 32 c and the notched tape are disposed within the rail or within the profile of the rail and thus may be packaged within the rail for a reduced profile drive system. - The notched
tape 32 a is routed alongchannels channel 14 a (FIG. 42 ). In the illustrated embodiment, thechannel 32 d is formed or extruded along thealuminum rail 14 c that is received in the molded lower rail orchannel 14 b, while thechannel 32 e is formed along the surface of the lower rail orchannel 14 b that faces toward and is bonded to the interior surface of the fixedwindow panel 15. One end of the notchedtape 32 a (such as the end of the portion of the tape that is inchannel 32 d) is connected to or attached to the carrier 32 f of the movable window panel (such as via a pin or tooth or pins or teeth being received in notches at the end of the tape), such that movement of the tape (via rotation of thetoothed wheel 32 c) moves the end of the tape and the movable window panel along the frame and fixed window panel. The other end or portion of the tape (seeFIGS. 46 and 47 ) is disposed in and moves along thechannel 32 e of the lower rail orchannel 14 b, which functions to guide and support the tape during operation of thedrive system 32. - The
channels FIG. 43 , the end of the tape attached to the carrier moves along thechannel 32 d and pulls at the carrier and movable window to open the window, with the other end of the tape moving alongchannel 32 e away from the toothed wheel. When the toothed wheel is rotated in the clockwise direction inFIG. 43 , the end of the tape attached to the carrier moves along thechannel 32 d and pushes at the carrier and movable window to close the window, with the other end of the tape moving along thechannel 32 e toward the toothed wheel. - Referring now to
FIGS. 49-58 , thedrive motor 24 ofdrive system 34 winds and unwinds aflexible cable 34 a about a spool or reel 34 b. Thecable 34 a is received in or disposed in a telescoping support tube or enclosure orconstruction 34 c that telescopingly extends when the cable is uncoiled or unwound and telescopingly retracts when the cable is coiled or wound. The cable is a flexible cable to allow for coiling at the reel or spool, yet is sufficiently resistant to flexing (when restrained by the tube) as it is extended and pushes the innermost section of the telescoping support tube outward. In the illustrated embodiment, thetelescoping tube support 34 c comprises three sections (a base section that receives a middle or intermediate section that receives an innermost section). - The
telescoping support tube 34 c is disposed along the channel orrail 14 a and, when extended, the end of the innermost section of the support tube reaches to around the mid-point of the window assembly (seeFIGS. 50 and 51 ). By connecting the cable or end of the innermost section of thetelescoping tube 34 c to the middle region of the carrier of the movable window panel, the movable window panel can be fully opened, whereby the middle of the movable window panel and the end of the innermost tube section approaches and is at or near the end of the base section of the tube. Optionally, if the tube were to connect at the end or side of the movable window panel, the base section may be smaller in length (and the tube may comprise four or five sections) to provide clearance at the base end between the carrier and end of the rail for the telescoping tube (when it is retracted). - As shown in
FIG. 55 , the telescoping tube is received in or at anend cap attachment 34 d, which guides and supports at least the base of the tube along the rail orchannel 14 a. The base portion of the tube may be further supported via formed (extruded or molded) receiving portions along the rail or channel, and additional supports may be formed along the rail or channel to guide and/or support the extended portions of the telescoping tube when the tube is at least partially extended. - Thus, the drive systems of the present invention provide for opening and closing the rear slider window assembly via a single flexible drive element or cable or tape or strip or the like that pulls the movable window panel in one direction (such as to open the window) and pushes the movable window panel in the other direction (such as to close the window). The drive systems include guides or structure that guide and support the flexible cable/tape to limit flexing or bending of the flexible cable/tape along the lower rail, particularly when the drive system is extending or uncoiling the flexible cable/tape to push the movable window panel along the frame.
