Description

Technical FieldThe subject matter described herein relates generally to window assemblies, and more particularly, to sliding window assemblies for vehicles.BackgroundSome vehicles have window assemblies that open and close in a sliding manner. In some of these vehicles, the window assembly has a fixed panel mounted on the vehicle and a moving panel (moving panel) that slides behind the fixed panel to open the window. When the moving panel slides to close the window, the moving panel sits offset from the fixed panel. In other words, the moving panel is slightly closer to the front part of the vehicle than the fixed panel. Such arrangements may cause problems with the window assembly, including degraded aesthetic appearance of the window assembly, gaps between the movement panel and the fixed panel that cause leakage of air or other environmental elements into a passenger compartment of the vehicle, and / or jamming or sticking of the components that move the movement panel.SummaryExample systems and other embodiments relate to sliding window assemblies. As mentioned above, some window assemblies suffer from various difficulties. For example, some window assemblies have movement panels that are out of alignment with the rest of the window assembly, which can cause aesthetic and mechanical problems as well. Thus, in at least one arrangement, a window assembly is provided having an aligned closing movement panel. By means of a closing alignment (flush closing) with the remainder of the window assembly, the movement panel improves the aesthetic appearance of the window assembly, reduces an opportunity for gaps (gaps) between the movement panel and the remainder of the window assembly, and generally eliminates jamming and / or sticking in movement of the movement panel.In one embodiment, a window assembly includes a fixed panel defining an opening and a rail attached to the fixed panel. The window assembly also has a guide provided on the rail and defining grooves. The window assembly also has a shoe that at least partially (sectionally) overlaps with the guide and defines the slots. The window assembly further includes a movement panel supported by the shoe and interacting (cooperating) with the guide by pins extending through the slots and into the grooves such that the slots, together with the grooves, cause the movement panel to slide within the slots and relative to the fixed panel between a closed state in which the movement panel blocks the opening and substantially aligns with the fixed panel and an open state in which the movement panel does not block (uncovers) the opening.In another embodiment, a window assembly includes a fixed panel defining an opening and a rail attached to the fixed panel. The window assembly also includes a guide provided on the rail and defining grooves having substantially equal depths within the guide. The window assembly also has a shoe that at least partially (sectionally) overlaps the guide and defines slots that include a first slot and a second slot. The first slot and the second slot define different shapes. The window assembly further includes a movement panel supported by the shoe and interacting (cooperating) with the guide by pins extending through the slots and into the grooves such that the slots, together with the grooves, cause the movement panel to slide within the slots and relative to the fixed panel between a closed state in which the movement panel blocks the opening and substantially aligns with the fixed panel and an open state in which the movement panel does not block (uncovers) the opening.In yet another embodiment, a window assembly includes a fixed panel defining an opening and a rail attached to the fixed panel. The window assembly also has a guide provided on the rail and defining grooves including a first groove and a second groove. The window assembly also has a shoe at least partially (sectionally) overlapping the guide and defining slots facing away from the panel. The slots include a first C-shaped slot overlapping with the first groove and a second L-shaped slot overlapping with the second groove. The window assembly also has a movement panel supported by the shoe by pins extending through the slots and into the grooves such that the slots, together with the grooves, cause the movement panel to slide within the slots and relative to the fixed panel between a closed state in which the movement panel blocks the opening and substantially aligns with the fixed panel and an open state in which the movement panel does not block (uncover) the opening. The pins include a first pin sliding within the first groove and the first slot and a second pin sliding within the second groove and the second slot.Brief Description of the DrawingsThe accompanying drawings, which form a part of the specification, illustrate various systems, methods and other embodiments of the invention.

As mentioned above, some window assemblies suffer from various difficulties. For example, some window assemblies have movement panels that are misaligned with the remainder of the window assembly, which can cause aesthetic and mechanical problems as well. Thus, in at least one arrangement, a window assembly has been provided having an aligning closure movement panel. By closing in alignment with the remainder of the window assembly, the movement panel improves the aesthetic appearance of the window assembly, reduces opportunities for gaps (gaps) between the movement panel and the remainder of the window assembly, and generally eliminates jamming and / or sticking in movement of the movement panel.Referring to FIG. 1A, a portion of a vehicle 100 is shown. In the application provided herein, a "vehicle" is any form of powered transport means. In one or more embodiments, the vehicle 101 is a motor vehicle. While arrangements related to motor vehicles are described herein, it should be understood that the embodiments are not limited to motor vehicles. In some implementations, the vehicle 100 may be any robotic device or form of motorized transportation means, for example, having windows and thus taking advantage of the functionality discussed herein in connection with sliding window assemblies. As shown in FIG. 1A, the vehicle 100 is a pickup truck (open bed truck) having a driver side 110 and a passenger side 120. In examples where the vehicle 100 is a left-hand drive vehicle, the driver side 110 is the side of the vehicle 100 on which the driver sits, and the passenger side 120 is the side of the vehicle 100 opposite the driver side 110. However, the driver side 110 and the passenger side 190 may be reversed in another arrangement. In any case applied herein, the vehicle 100 is generally a left-hand drive vehicle. Among the other components of the pickup truck, the pickup truck has a bed (cargo bed) 130, a passenger compartment 140, a roof 150, and a window assembly 160. For example, in one embodiment, as shown, the window assembly 160 is a rear sliding window assembly 160 for the pickup truck. Here, "rear" means that the window assembly 160 faces the bed 130. However, in other embodiments, the window assembly 160 is aligned along a side of the vehicle 100, such as the driver side 110 or the passenger side 120.The window assembly 160 includes one or more panels. In one embodiment, the panels are glass panels. In other embodiments, the panels are of plexiglass, plastic, acrylic or other material suitable for use as a window. In other words, the panels may be formed of a substantially transparent and / or transparent material that closes the passenger compartment 140 while allowing light to pass through and provide vision to the exterior of the vehicle 100 for occupants within the vehicle 100. It should be understood that the panels may be formed of the same material, or the panels may be formed of different materials. Moreover, the panels are generally thin planar components that are substantially flat (planar) or slightly curved.In one embodiment, as shown in FIGS. 1A and 1B, for example, the window assembly 160 includes a fixed panel 170 and a moving panel (a moving panel) 180. In the present application, "fixed" means that the fixed panel 170 does not substantially move with respect to the vehicle 100. In one arrangement, the fixed panel 170 is attached to the vehicle 100 and defines an opening 190. As shown, the opening 190 is substantially centered within the fixed panel 170. However, in other arrangements, the opening 190 may be arranged differently with respect to the fixed panel 170 (e.g., the opening 190 may be arranged closer to one side of the vehicle 100 than to another side of the vehicle 100).The movement panel 180 moves with respect to the fixed panel 170 to block and clear the opening 190, in one example. In other words, the moving panel 180 moves to open and close the opening 190 of the window assembly 160. When the window assembly 160 is in a closed state, such as shown in FIGS. 1A, 1B, and 2A, the movement panel 180 fully or substantially covers the opening 190 to block the opening 190 from air, water, and other environmental elements passing through the opening 190. When the window assembly 160 is in an open state, such as shown in FIG. 2B, the movement panel 180 does not substantially cover the opening 190 or the movement panel 180 fully uncovers the opening 190 to allow air, water, and other environmental elements to pass through the opening 190.Referring back to FIG. 1B, when the window assembly 160 is in the closed state, the movement panel 180 substantially aligns with the fixed panel 170 (e.g., the movement panel 180 closes in alignment with the fixed panel 170). More specifically, when the window assembly 160 is in the closed state, the moving panel 180 is disposed substantially in the same plane as the fixed panel 170. In one example, the central axes of the planes are spaced approximately 0 mm in the general y-direction. In other words, the moving panel 180 and the fixed panel 170 appear as a continuous panel when the window assembly 160 is in the closed state. As a result, the window assembly 160 has a pleasing aesthetic appearance. For example, in the closed state, the window assembly 160 appears as a continuous panel and the motion panel 180 is not readily recognizable. As described in further detail below, the window assembly 160 has a drive system that allows the movement panel 180 to be aligned with the fixed panel 170.Referring again to the fixed panel 170, referring now to FIGS. 2A and 2B, the fixed panel 170 defines a perimeter (perimeter) 200. Perimeter 200 is, in one example, an edge of fixed panel 170 that substantially surrounds fixed panel 170. In some cases, the fixed panel 170 is attached to the vehicle 100 on the perimeter 200. Moreover, in one arrangement, perimeter 200 has a top edge 202, a bottom edge 204, a first side edge 206, a second side edge 208. In one arrangement, as described herein, the top edge 202 is disposed adjacent the roof 150 and the bottom edge 204 is disposed opposite the top edge 202 (e.g., adjacent the bed 130). Moreover, in an arrangement as described herein, the first side edge 206 is disposed on the driver side 110 and the second side edge 208 is disposed opposite the first side edge 206 (e.g., on the passenger side 120). However, in other arrangements, the first side edge 206 may be disposed on the passenger side 120 and the second side edge 208 may be disposed on the driver side 110. The fixed panel 170 also defines a back side and a front side 210. Here, reference is made to the rear side being viewed from the outside of the vehicle 100 (for example, the rear side faces the bed 130), and the front side 210 being visible from the inside of the vehicle 100 (for example, the front side 210 faces the passenger compartment 140). However, in other arrangements, the rear side faces the passenger compartment 140 and the front side 210 faces the bed 130.Referring back to the moving board 180, as mentioned above, the moving board 180 moves with respect to the fixed board 170. As will be described in more detail below, in one embodiment, the motion panel 180 slides with respect to the fixed panel 170. More specifically, in one arrangement, the motion panel 180 slides in a direction of the first side edge 206 and the second side edge 208. In one example, the movement panel 180 moves from the opening 190 to the first side edge 206 and back to the opening 190. In another example, the movement panel 180 moves from the opening 190 to the second side edge 208 and back to the opening 190. In other words, the movement panel 180 generally moves in a lateral direction (lateral direction) of the vehicle 100 (e.g., substantially along the x-axis of FIG. 1A ). In some examples, the location of the opening 190 within the fixed panel 170 and / or the direction of movement of the movement panel 180 is selected by the manufacturer of the original equipment of the vehicle 100 (OEM). The original equipment manufacturer (OEM) may select these features based on the type of vehicle 100, the manufacturing process of the vehicle 100, the customer demand, and / or other factors.To facilitate movement of the movement panel 180, in some examples, the window assembly 160 has a frame 212 for the movement panel 180. The frame 212 places the motion panel 180 under and connects the motion panel 180 to the rest of the window assembly 160. As described in more detail below, the frame 212 may assist in facilitating movement of the movement panel 180. In one embodiment, the frame 212 is an injection molded plastic part that substantially surrounds an edge of the movement panel 180. In another example, the frame 212 does not surround the edge of the movement panel 180, and instead is attached to only one side of the movement panel 180 by, for example, an adhesive. As such, the frame 212 not only facilitates the movement of the moving panel 180, but also helps protect the moving panel 180 from damage.As mentioned above, the window assembly 160 also has a drive system. The drive system includes drive components operable to move the motion panel 180 such that the motion panel 180 is in alignment with the fixed panel 170 in the closed position. To accomplish this, the drive system includes one or more components operable to move the motion panel 180 in multiple directions. More specifically, the drive system is operable to move the moving panel 180 substantially in the y-direction so that the moving panel 180 slides toward and away from the opening 190. The drive system is also operable to move the moving board 180 substantially in the x direction so that the moving board 180 slides and passes the fixed board 170. In other words, the drive system is operable to direct the moving panel 180 both substantially parallel to the fixed panel 170 and substantially perpendicular to the fixed panel 170. In one embodiment, when the window assembly 160 is in the closed state, the drive system is operable to direct the motion panel 180 away from the opening 190 in the substantially y-direction to clear the opening and create a clearance for the motion panel 180 to pass the fixed panel 170 in the substantially x-direction such that the window assembly 160 is in the open state. In contrast, in one embodiment, when the window assembly 160 is in the open state, the drive system is operable to pass the motion panel 180 past the fixed panel 170 substantially in the x direction toward the opening 190 and the drive system is operable to slide the motion panel 180 into the opening 190 generally in the y direction to block the opening 190 such that the window assembly is in the closed state. Further details of the propulsion system components are described in more detail below.In one embodiment, as shown in FIGS. 2A and 2B, the propulsion system includes a motor 214, cables, and rails. In one arrangement, the motion panel 180 is supported by the rails, the cables are directly or indirectly connected to the motion panel 180, and the motor 214 operates the cables such that the motion panel 180 slides along the rails. In one embodiment, as described in more detail below, the drive system is interfaced to the motion panel 180, for example, via the frame 212 to slide the motion panel 180. Each drive component and also the operation of the drive system is described in more detail below.As shown in the drawings, the motor 214 is mounted on the fixed panel 170. In one example, the motor 214 is adhered to the fixed panel 170. In another example, the motor 214 is disposed in a motor housing 216, and the motor housing 216 is attached to the fixed panel 170. The motor housing 216 is attached to the fixed panel 170 by an adhesive (in other words, the motor housing 216 is adhered to the fixed panel 170) in one embodiment. The motor 214 may be attached to the motor housing 216 by threaded fasteners in one example. The motor 214 (and similarly the motor housing 216) is mounted to the fixed panel 170 between the top edge 202 and the bottom edge 204. As shown, the motor 214 is mounted to the fixed panel 170 substantially equidistant from the top edge 202 and the bottom edge 204. However, in other arrangements, the motor 214 may be mounted along the fixed panel 170 closer to one of the top edge 202 and the bottom edge 204. Moreover, in some cases, the motor 214 is mounted to the fixed panel 170 adjacent to either the first side edge 202 or the second side edge 208. More specifically, the motor 214 may be mounted to the fixed panel 170 approximately a few inches from the first side edge 206 or the second side edge 208. As shown in the drawings, the motor 214 is mounted to the fixed panel 170 adjacent the first side edge 206.To provide power (power) to the engine 214 once the window assembly 160 is installed on the vehicle 100, the window assembly 160 also includes wiring harness (harness) 218 in one arrangement. The wiring harness 218, in one example, is mounted to the engine 214 and electrically connects the engine 214 to electrical components (e.g., a controller, a power source, etc.) of the vehicle 100. In one embodiment, the wire harness 218 is attached to the fixed panel 170 prior to installation on the vehicle 100. For example, the wiring harness 218 may be attached to the fixed panel 170 with a clip (clip) 220 or other attachment device before the window assembly 160 is installed on the vehicle 100. Other methods of securing the wire harness 218 to the fixed panel 170 include stitching, tape, etc.Referring now to the rails, in one embodiment, the window assembly 160 includes an upper rail 222 and a bottom rail (lower rail) 224. As shown, the upper rail 222 is disposed adjacent the upper edge 202, and the lower rail 224 is disposed adjacent the bottom edge 204. The rails 222 / 224 are attached to the front-fixed panel 170 by, for example, adhering. The rails 222 / 224 extend along the top edge 202 and the bottom edge 204 substantially along the x-axis. For example, in one arrangement, as shown, the rails 222 / 224 span a portion of the top edge 202 and the bottom edge 204. The rails 222 / 224 may be formed of metal, plastic, or other material having suitable stiffness to support the motion panel 180 as the motion panel 180 slides along the rails 222 / 224. Moreover, in one or more aspects (e.g., in terms of length, size, material, etc.), the rails 222 / 224 may be substantially identical, or the top rail 222 and the bottom rail 224 may be different in one or more of these aspects.Referring now to the cables (wires), in one embodiment, the window assembly 160 includes an upper cable 226 and a bottom cable (lower cable) 228. In the arrangement shown, the upper cable 226 is disposed within the upper rail 222 and the bottom cable 228 is disposed within the bottom rail 224. Moreover, in one application, the upper cable 226 is disposed closer to a central portion of the fixed panel 170 while the bottom cable 228 is disposed closer to the perimeter 200. However, in other arrangements, the upper cable 226 may be disposed closer to the perimeter 200 and the bottom cable 228 may be disposed closer to the central portion of the fixed panel 170. In either case, the cables 226 / 228 are directly and / or indirectly connected to the motor 214 and the movement panel 180, and are operable by the motor 214 such that the movement panel 180 slides along the rails 222 / 224. More specifically, in one arrangement, the cables 226 / 228 are connected to the motor 214 and to the frame 212. In one example, the cables 226 / 228 define grooves and the motor 214 includes a drive gear that drives the cables 226 / 228 through the grooves. However, the motor 214 and the cables 226 / 228 may interface in another manner. Also in one arrangement, the motor 214 rotates clockwise and / or counterclockwise to actuate the cables 226 / 228 in a push-pull manner to slide the motion panel 180.Referring again to FIGS. 2A and 2B, operating the motor 214 in a pushing manner slides the motion panel 180 toward the first side edge 206 to clear the opening 190, while operating the motor 214 in a pulling manner causes the motion panel 180 to slide toward the opening 190. However, it should be understood that the push-pull manner may be reversed. For example, in another arrangement, operating the motor 214 in a pulling manner slides the movement panel 180 toward the first side edge 206 to clear the opening 190, while operating the motor 214 in a pushing manner causes the movement panel 180 to slide toward the opening 190. The direction of the push-pull operation can be decided by the OEM.The cables 226 / 228, in one embodiment, extend to the rails 222 / 224 substantially following the perimeter 200 and offset from the perimeter 200. As such, cables 226 / 228 generally follow perimeter 200 such that cables 226 / 228 do not substantially interfere (do not interfere) with the viewing area through fixed panel 170. In some cases, the cables 226 / 228 are generally flexible, and accordingly, the cables 226 / 228 must be directed to follow the paths shown in the drawings. As such, in one embodiment, the window assembly 160 may include tubes / hoses. The tubes / hoses may house the cables 226 / 228 and direct the cables 226 / 228 from the motor housing 216 to the rails 222 / 224. In one example, the window assembly 160 includes a first tube (hose) 32, a second tube (hose) 232, a third tube (hose) 234, and a fourth tube (hose) 236. As shown, the first tube 230 accommodates a portion of the upper cable 226, the second tube 232 accommodates the remainder of the upper cable 226, the third tube 234 accommodates a portion of the ground cable 228, and the fourth tube 236 accommodates the remainder of the ground cable 228. However, it should be understood that the tubes 230-234 may accommodate the cables 226 / 228 in other ways. In any event, the tubes 230-234 may be substantially rigid and hollow in such a manner that the tubes 230-234 locate the cables 226 / 228 in the arrangements shown in the drawings, while the cables 226 / 228 may slide within the tubes 230-234. More specifically, in one arrangement, tubes 230-234 extend between motor housing 216 and rails 222 / 224 by following perimeter 200 and being offset from perimeter 200. Moreover, as mentioned above, the motor 214 may be housed in a motor housing 216. Accordingly, in one embodiment, the cables 226 / 128 are configured to pass through the motor housing 216 such that the cables 226 / 228 may be in contact with the motor 214. Accordingly, the cables 226 / 228 extend from the rails 222 / 224, through the tubes 230-234, and into the motor housing 216.As mentioned above, the drive system is operable to slide the moving board 180 in multiple directions. As described above, the drive system is operable to slide the motion panel 180 along the rails 222 / 224 generally in the x-direction and substantially parallel to the fixed panel 170. In addition, the drive system is operable to slide the moving board 180 generally in the y direction and substantially perpendicular to the fixed board 170. Accordingly, in addition to the motor 214, the cables 226 / 228, and the rails 222 / 224, the drive system includes one or more other components that facilitate movement of the motion panel 180 in a plurality of directions. These components are described in more detail below.Referring now to FIGS. 3A and 3B, a close up of a portion of the bottom rail 224 and the motion panel 180 is shown. In one embodiment, the window assembly 160 includes a guide 300 and a shoe 310, see FIG. 3B. The guide 300 and the shoe 310 function with each other to dictate the movement of the movement panel 180. In one arrangement, the guide 300 is provided on the bottom rail 224 and includes grooves that guide the moving panel 180 when the moving panel 180 slides in the direction of the bottom rail 224. As shown in FIG. 3A, the grooves include a first groove 320 and a second groove 330. The first groove 320 may be disposed closer to the second side edge 208 of the fixed panel 170 than the second groove 330, and the second groove 330 may be disposed closer to the first side edge 206 than the first groove 320. Further details of the grooves 320 / 330 are described in more detail below and in conjunction with FIGS. 4A and 4B.In one embodiment, the guide 300 is an injection molded or 3D printed component that is manufactured separately from the bottom rail 224 and is attached to the bottom rail 224. The guide 300 may be attached to the bottom rail 224 by adhesive, by snap-in or snap-in structure, by fasteners, or other methods of attachment. The production of the guide 300 separately from the bottom rail 224 can be advantageous if the guide 300 and the bottom rail 224 are formed from different materials. For example, the guide 300 may be injection molded from plastic, plastic, etc., while the bottom rail 224 is formed from metal such as steel. In another embodiment, the guide 300 and the bottom rail 224 are integrally formed (as a unit) as a single component. For example, the guide 300 and the bottom rail 224 may be injection molded or manufactured by 3D printing with each other, which may provide the advantage of lower manufacturing cost, shorter manufacturing times, etc. In any event, in one embodiment, the guide 300 is static with respect to the bottom rail 224 and the motion panel 180 slides along the guide 300 without causing movement of the guide 300.As mentioned above, with reference to FIG. 3B below, the window assembly 160 also includes a shoe 310. In one embodiment, the shoe 310 slides along the bottom rail 224 to guide movement of the movement panel 180 along the bottom rail 224 and the guide 300. The shoe 310 includes slots similar to the grooves of the guide 300 that direct movement of the movement panel 180. In one embodiment, the slots include a first slot 340 and a second slot 350. The first slot 340 may be disposed closer to the second side edge 208 of the fixed panel 170 than the second slot 350, and the second slot 350 may be disposed closer to the first side edge 206 than the first slot 340. Moreover, in an arrangement, the first slot 340 overlaps with the first groove 320, and the second slot 350 overlaps with the second groove 330. Further details of the slots 340 / 350 are described in more detail below in connection with FIGS. 4A and 4B.As described in more detail below, in some cases, the shoe 310 moves with respect to the motion panel 180 (e.g., the shoe 310 slides along the floor rail 224 while the motion panel 180 remains at substantially the same location), and in other cases, the shoe 310 and the motion panel 180 move with each other (e.g., the shoe 310 presses or pulls the motion panel 180). As described in more detail below, the ground cable 228 is connected to the shoe 310, and movement of the ground cable 228 causes the shoe 310 to slide. Moreover, as will be described in more detail below, the shoe 310 is provided at least partially (sectionally) on the floor rail 224. In one example, the shoe 310 is supported by both the guide 300 and the floor rails 224. Like the guide 300, the shoe 310 may be injection molded, manufactured by 3D printing, or manufactured by another method. The shoe 310 may be made of a plastic material, a plastic material, a metal material, or another material.As mentioned above, the slots 340 / 350, along with the grooves 320 / 330, cause the movement panel 180 to slide along the bottom rail 224. As such, the movement panel 180 is supported by the guide 300 and within the shoe 310. In one embodiment, the window assembly 160 also has pins attached to the frame 212 that supports the movement panel 180 on the guide 300, thereby allowing the movement panel 180 to slide along the floor rail 224 within the shoe 310. More specifically, in one arrangement, the pins extend through the slots 340 / 350 and seat within the grooves 320 / 330. In one embodiment, the pins include a first pin 360 and a second pin 370. The first pin 360 and the second pin 370 may be attached to the frame 212 at opposite sides of the movement panel 180. For example, the first pin may be attached to one side of the frame 212 closer to the second side edge 208 of the fixed panel 170 than the second pin 370, and the second pin 370 may be attached to the other side of the frame 212 closer to the first side edge 206 than the first pin 360. In the embodiment shown, moreover, the first pin 360 extends through the first slot 340 and sits within the first slot 320, while the second pin 370 extends through the second slot 350 and sits within the second slot 330. Accordingly, the first pin 360 slides within the first groove 320 and the second slot 350, and the second pin 370 slides within the second groove 330 and the second slot 350. As the motion panel 180 passes along the grooves 320 / 333 and the slots 340 / 350, the grooves 320 / 330 and the slots 340 / 350 direct the motion of the motion panel 180 in a plurality of directions, as discussed above. The direction of movement of the movement panel 180 is achieved due to the shapes of the grooves 320 / 330 and the slots 340 / 350, as described in more detail below in connection with FIGS. 5A and 5B.Referring now to FIGS. 4A and 4B, further details of the window assembly 160 are described below. FIG. 4A shows a cross-sectional side view along the bottom rail 224, while FIG. 4B shows a perspective view of various components of the propulsion system. FIG. 4A shows an example of an adhesive 400 that secures the bottom rail 224 to the fixed panel 170. It should be understood that the upper rail 222 may be similarly secured to the fixed panel 170. FIG. 4A also shows an example of a weather strip 410 for the window assembly 160. The weather strip 410 is attached to the frame 212 in one embodiment. As such, and as described above, when the movement panel 180 moves to the closed state for the purpose of blocking the opening 190, the weather strip 410 substantially seals the space between the frame 212 and the opening 190, thereby substantially preventing air, water, or other environmental elements from entering the vehicle 190 through the opening 190. Further details of the weather strip 410 are described in more detail below.Figure 4A also shows the motion panel 180 in both the closed aligned position within the opening 190 and the position offset from the fixed panel 170 (shown in phantom lines). As mentioned above, when the moving panel 180 is displaced from the fixed panel 170, the moving panel 180 has a clearance to slide along the bottom rail 224 to block and release the opening 190. Further details of the movement of the movement panel 180 are described in more detail below.Referring now to FIG. 4B, an example of the second pin 370 is shown extending through the second slot 350 and seated within the second groove 330. FIG. 4B also shows a cable channel 420. The cable channel 420 receives the ground cable 228 and allows the ground cable 228 to slide within the ground rail 224. Sliding the ground cable 228 within the rail 224 causes the shoe 310 to slide when the ground cable 228 is in contact with the shoe 310.Referring now also to Figures 5A and 5B, the guide 300 and shoe 310 are shown in greater detail individually. Referring now to FIG. 5A, as mentioned above, the guide 300 includes a first groove 320 and a second groove 330. The first groove 320 may generally span a first half of the guide 300 (e.g., a half of the guide 300 proximate the second side edge 208) and the second groove 330 may generally span a second half of the guide 300 (e.g., a half of the guide 300 proximate the first side edge 206). For example, as shown, in one embodiment, the grooves 320 / 330 define different shapes. In other words, the first groove 320 defines a different shape than the second groove 330. In one example, the first groove 320 is substantially J-shaped and the second groove 330 is substantially S-shaped. Further details of each mold are described below.In one arrangement, the first groove 320 defines a J-leg 500, a J-bend 502, and a J-end 504. In one arrangement, the second groove 330 defines an S-leg 506, an S-bend 508, and an S-end piece 510. For example, in one embodiment, as shown, the J-foot 500 is substantially straight and spans most of the first half of the guide 300 and the S-foot 506 is substantially straight and spans most of the second half of the guide 300. As such, the J-foot 500 and the S-foot 506 direct the first pin 360 and the second pin 370, respectively, such that the motion panel 180 moves substantially parallel to the fixed panel 170 when the window assembly 160 performs a motion between the closed state and the open state. Moreover, in one embodiment, the J-bend 502 and the S-bend 508 bend from the J-foot 500 and the S-foot 506, respectively, toward the fixed panel 170. As a result, the J-bend 502 and the S-bend 508 direct the first pin 360 and the second pin 370, respectively, such that the motion panel 180 moves in both the x-direction and the y-direction. More specifically, as the pins 360 / 370 move along the J bend 502 and the S bend 508 during opening of the window assembly 160, the J bend 502 and the S bend 508 orient the pins 360 / 370 and thus the movement panel 180 away from the fixed panel 170 and the opening 190. In contrast, when the pins 360 / 370 move along the J bend 502 and the S bend 508 during closing of the window assembly 160, the J bend 502 and the S bend 508 direct the pins 360 / 370 and thus the movement panel 180 toward the fixed panel 170 and the opening 190.Referring now to J-end 504 and S-end piece 510, J-end 504 and S-end piece 510 are disposed at a position on guide 300 such that when first pin 360 and second pin 370 are positioned on J-end 504 and S-end piece 510, respectively, travel panel 180 is flush with fixed panel 170 within opening 190. Moreover, the J end 504 and the S end piece 510 are disposed closer to the fixed panel 170 and the opening 190 than the J leg 500, the J bend 502, the S leg 506, and the S end piece 510. As such, in one embodiment, the J-end 504 and the S-end piece 510 are substantially aligned with the sides of the opening 190. On the other hand, the J-leg 500 and the S-leg 506 are disposed farther away from the fixed panel 170 and the opening 190 than the J-end 504 and the S-end 510. In other words, the J-foot 500 and the S-foot 506 are offset from the fixed panel 170 by a distance. Moreover, the distance between the J end 504 and the J foot 500 and / or the distance between the S end piece 510 and the S foot 506 is at a minimum of the depth of the fixed panel 170 and the motion panel 180 (in other words, the distance is the minimum amount that the motion panel 180 must move in the y direction to move from the flush closed position to behind the fixed panel 170). However, some additional distance between the J end 504 and the J foot 500 and between the S end piece 510 and the S foot 506 is advantageous to allow play for the motion panel 180 to pass the fixed panel 170 as the motion panel 180 is guided within the grooves. Further details of the J-end 504 and the S-end 510 are described in more detail below in connection with FIG. 7.Referring again to FIG. 5A, in one arrangement, the guide 300 defines a wall 512 between the first groove 320 and the second groove 330. The wall 512 separates the first groove 320 and the second groove 330 such that the first pin 360 does not slide within the second groove 330 and the second pin 370 does not guide within the first groove 320. The guide 300 may define the wall 512 via injection molding, or the wall 512 may be a separate component attached to the guide 300. Moreover, in one embodiment, the grooves 320 / 330 have substantially equal depths. For example, the grooves 320 / 330 may have a depth of a few millimeters, a few centimeters, etc. However, in some cases, the grooves 320 / 330 do not extend all the way through the guide 300. Moreover, the depths of the grooves 320 / 330 correspond to the lengths of the pins 360 / 370 in one case. Accordingly, in one arrangement, the pins 360 / 370 also define substantially equal lengths.Referring now to FIG. 5B, as mentioned above, the shoe 310 may include a first slot 340 and a second slot 350. In one embodiment, the slots 340 / 350 extend through the shoe 310 such that the pins 360 / 370 extend through the shoe 310 and into the guide 300. Moreover, in one arrangement, the first slot 340 and the second slot 350 define different shapes. In other words, the first slot 340 defines a different shape than the second slot 350. In one example, the first slot 340 is substantially C-shaped and the second slot 350 is substantially L-shaped. The C-shape of the first slot 340 and the L-shape of the second slot 350 may face away from the fixed panel 170. In other words, looking at the shoe 310 from above and from inside the passenger compartment 140 of the vehicle 100, the C-shape and the L-shape are rearward (rearward). Further details of each shape of the slots 340 / 350 are described below.Referring now to the first slot 340, in one arrangement, the first slot 340 defines a first C-end 514, a C-curve 516, and a second C-end 518. The first C-end 514 is, in one embodiment, closer to the fixed panel 170 than the second C-end 518, and the C-curve 516 bends between the first C-end 514 and the second C-end 518. When the moving panel 180 moves along the bottom rail 224 as the window assembly 160 moves from the closed state to the open state, the C-curve 516 pulls the first pin 360 away from the fixed panel 170 and the opening 190 such that the moving panel 180 inclines away from the fixed panel 170. Tilting the motion panel 180 away from the fixed panel 170 allows the motion panel 180 to move from an aligned closed position within the opening 190 to a position offset from the opening 190 such that the motion panel 180 can slide along the rail to clear the opening 190. In contrast, when the moving panel 180 moves along the bottom rail 224 as the window assembly 160 moves from the open state to the closed state, the C-curve 516 presses the first pin toward the fixed panel 170 and the opening 190 such that the moving panel 180 inclines toward the fixed panel 170. Tilting the motion panel 180 toward the fixed panel 170 facilitates closing the motion panel 180 in alignment with the fixed panel 170 within the opening 190. Further details of the first slot 340 are described in more detail below.Referring now to the second slot 350, in one arrangement, the second slot 150 defines a first L-end 520, a long arm 522, a corner 524, a short arm 526, and a second L-end 528. The first L-end 520 is, in one embodiment, closer to the fixed panel 170 than the second L-end 528. Moreover, in one arrangement, the long arm 520 extends from the first L-end 520 to the corner 524, and the short arm 526 extends away from the fixed panel 170 from the second L-end 528 to the corner 524. In some cases, the long arm 522 is longer than the short arm 526. Also, in some cases, the long arm 522 is substantially parallel to the fixed panel 170, while the short arm 526 is substantially perpendicular to the fixed panel 170 and the long arm 522. The different geometries of the second slot 350 serve different purposes during opening and closing of the window assembly 160. For example, the short arm 526 pushes and pulls the second pin 170 during opening and closing of the window assembly 160, thereby pushing and pulling the moving panel 180 along the bottom rail 224. In another example, the second pin 71 sits within the long arm 522 when the window assembly 160 is in the closed state. Since the long arm 522 is substantially parallel to the fixed panel 170, when the second pin 170 is seated within the long arm 522 when the window assembly 160 is in the closed state, the long arm 522 prevents the second pin 370 from moving substantially in the y direction with respect to the fixed panel 170. In this manner, the long arm 522 prevents the movement panel 180 from sliding in a direction substantially perpendicular to the fixed panel 170, such that the movement panel 180 is locked to the fixed panel 170 within the opening 190 in the closed state. As a result, if a person or object outside the vehicle 100 were to press on the motion panel 180 in a direction substantially perpendicular to the plane of the motion panel 180, the motion panel 180 would not open.As just described, the shapes of the slots 340 / 350 and the grooves 320 / 330 serve different purposes during opening and closing of the window assembly 160. Moreover, the shapes of the slits 340 / 350 and the grooves 320 / 330 function with each other so that the moving panel 180 slides in a plurality of directions to change the state of the window assembly 160 between the open and closed states. In addition to the open and closed states described above, the window assembly 160 also has a ventilation state and a sliding state. In the ventilating state, the moving panel 180 is inclined away from the fixed panel 170, but is still generally disposed at a position aligned with the opening 190. In the sliding state, the moving panel 180 slides with respect to the fixed panel 170 between the open state and the closed state. Each state of the window assembly 160 is described in more detail below in conjunction with the movement of the movement panel 180 in conjunction with Figs. 6A to 6E.Referring first to FIG. 6A, an example of the window assembly 160 is shown in a closed state 600. In the closed state 600, the first pin 360 is disposed within the first C end 514 and the J end 504, while the second pin 370 is disposed within the first L end 520 and the S end piece 510. As a result, in the closed state 600, the moving panel 180 is locked at a location where it is aligned with the fixed panel 170 within the opening 190, thereby blocking the opening 190.Referring now to FIG. 6B, with FIG. 6B showing an example of the window assembly 160 moving from the closed state 600 to the venting state. In other words, the window assembly 160 is in a first intermediate state 610. In the first intermediate state 610, the shoe 310 has started to slide along the bottom rail 224 substantially in the x-direction, and the movement panel 180 has not substantially moved within the opening 190. In the first intermediate state 610, the first pin 360 moves along the C-curve 516 from the first C-end 514 to the second C-end 518. Moreover, in the first intermediate state 610, the first pin 360 moves along the J-bend 502 from the J-end 504. With respect to the second pin 370, in the first intermediate state 610, the second pin 370 slides along the long arm 522 from the first L end 520 to the corner 524, and the second pin 370 is located within the S end piece 510. Accordingly, in the first intermediate state 610, the motor 214 operates to move the ground cable 228 such that the shoe 310 slides along the ground rail 224 and the shoe 310 slides first in front of the movement panel 180.Referring now to FIG. 6C, an example of the window assembly 160 is shown in a venting state 620. In the ventilation state 620, the moving panel 180 is inclined away from the fixed panel 170 toward the passenger compartment 140. In other words, in the ventilation state 620, one side of the moving panel 180 is offset from the opening 190 so that air, water, and other surrounding elements can pass through a narrow space between the moving panel 180 and the opening 190 on the side of the moving panel 180 inclined away from the fixed panel 170. Accordingly, in the ventilation state 620, the plane of the moving panel 180 is substantially not aligned with the plane of the fixed panel 170. Instead, the plane of the moving panel 180 is angled from the plane of the fixed panel 170. In the venting state 620, the first pin 360 is disposed within the second C-end 518 and the J-bend 502, and the second pin 370 is disposed within the corner 524 and the S-end 510.Referring now to FIG. 6D, with FIG. 6D showing an example of the window assembly 160 moving from the venting state 620 to the sliding state. In other words, the window assembly 160 is in a second intermediate state 630. In the second intermediate state 630, the second pin 370 is pulled away from the fixed panel 170 in a direction toward the passenger compartment 140. Accordingly, in the second intermediate state 630, the motion panel 180 is rotated such that the plane of the motion panel 180 is re-aligned with and substantially parallel to the fixed panel 170. However, unlike the first intermediate state 610, in the second intermediate state 630, the moving panel 180 is substantially not aligned with the fixed panel 170, but rather is offset from the fixed panel 170. In the second intermediate state 630, the motion panel 180 slides in the y-direction and rotates rather than moving substantially in the x-direction. Accordingly, in the second intermediate state 630, the first pin 360 is disposed within the second C-end 518 and within the J-foot 500, while the second pin 370 is disposed within the short arm 526 and the S-bend 508.Referring finally to FIG. 6E, an example of the window assembly 160 is shown in a sliding state 640. In the sliding state 640, the motion panel 180 is either ready to slide in the x direction, slides in the x direction, or is located at a position within the J foot 500 and the S foot 506 offset from the fixed panel 170 and substantially parallel to the fixed panel 170. In the sliding state 640, the first pin 360 is disposed within the J-foot 500 and the second C-end 518, while the second pin 370 is disposed within the S-foot 506 and the second L-end 528. As a result, the second L-end 528 pulls and presses the movement panel 180 when the shoe 310 is operated to slide along the floor rail 224.As shown in FIGS. 6A to 6E, the shoe 310 is operated to slide substantially in one direction, the x direction. In other words, the shoe 310 is operated to slide substantially in one direction along the bottom rail 224. However, as a product of the shapes of the grooves 320 / 330 and the slots 340 / 350, movement of the shoe 310 in the x-direction causes movement of the movement panel 180 in two directions - both in the x-direction and in the y-direction. As a result, as mentioned above, the moving board 180 may pass along the fixed board 170 to block and release the opening 190, and the moving board 180 may also slide into the opening 190 to close in alignment with the fixed board 170.Referring now to FIG. 7, in one embodiment, the first slot 340 and the second slot 350 cooperate with each other to accommodate manufacturing variability (tolerance) in the window assembly 160. In some cases, manufacturing tolerances are permitted in the manufacture of one or more components of the window assembly 160. For example, the motion panel 180 defines a motion panel width 700 that may have a tolerance of, for example, a few millimeters. Moreover, the weather strip 410 may have a tolerance in the thickness of the material of the weather strip 410, the width of the weather strip 410, etc. In yet another example, the opening 190 also defines a width that may also have a tolerance. In some cases, if the dimensions of the components of the window assembly 160 fall within these tolerances, the movement panel 180 may not seat perfectly within the opening 190 and align with the fixed panel 170. This may result in gaps (gaps) between the movement panel 180 and the fixed panel 170, allowing air, rain, or other environmental elements to enter the passenger compartment 140, or this may result in the movement panel 180 not being able to seat entirely within the opening 190 for blocking the opening 190. Accordingly, as mentioned above, the first slot 340 and the second slot 350 are configured to accommodate this variability (tolerance).As mentioned above, when the window assembly 160 is in the closed state 600, the first pin 360 seats within the J-end 504 of the first groove 320. The J-end 504 defines a J-end width 710 that is substantially equal to or only slightly greater than a diameter of the first pin 360. As a result, when the first pin 360 is seated within the J-end 504, the first pin 360 will not substantially move within the first groove 320 in the generally x-direction. As a result, the J end 504 fixes the position of the moving board 180 with respect to the fixed board 170 at a location near the J end 504. On the other hand, the S-end 510 of the second groove 330 defines an S-end length 720. The S-end 510 extends substantially parallel to the fixed panel 170, and the S-end length 720 is substantially greater than the J-end width 710 compared to the diameter of the second pin 370. For example, the S-end piece 510 may have a length of about 3 times the diameter of the second pin 370. As a result, when the window group 160 is in the closed state 600, the S-tail length 720 accommodates various locations where the second pin 370 can sit with respect to the first pin 360, which may be due to manufacturing variations in the moving panel width 700, the width of the weather strip 410, the width of the opening 190, etc.While FIGS. 3A-7 show a bottom portion of the window assembly 160 (e.g., the bottom rail 224, the bottom cable 228, the guide 300, the shoe 310, the pins 360 / 370, etc.), it should be understood that the window assembly 160 may also include such components at an upper portion of the window assembly 160. For example, a second guide and shoe may be provided on the upper rail 222, the frame 212 may include upper pins disposed within grooves of the second guide and slots of the second shoe, and the upper cable 226 may cause sliding of the second shoe. In this manner, the window assembly 160 may be mirrored in substantially one or more relationships about a center, a longitudinal axis of the window assembly 160 (e.g., a central axis of the window assembly 160 extending substantially in the x-direction). The components at the upper portion of the window assembly 160 may function exactly as described with respect to the components shown in Figures 3A-7.The arrangements described herein provide the advantage of an aligned closing sliding window assembly. The flush-closing window assembly improves the aesthetic appearance of the window assembly by, for example, appearing as a continuous panel rather than two separate panels that are offset from each other. Moreover, the arrangements described herein provide the advantage of sealing the window assembly even when manufacturing tolerances are present in the components of the window assembly. Finally, the arrangements described herein provide the advantage of an aligning sliding window assembly that operates in a smooth manner without the components of the window assembly blocking or sticking.Detailed exemplary embodiments are described above.

In one embodiment, a window assembly includes a fixed panel (fixed panel) 170 defining an opening and a rail 224 attached to the fixed panel 170.
