Detailed Description

Reference will now be made in detail to embodiments of the present disclosure, examples of which are described herein and illustrated in the accompanying drawings. While the present disclosure will be described in connection with embodiments and/or examples, they are not intended to limit the present disclosure to these embodiments and/or examples. On the contrary, the present disclosure covers alternatives, modifications, and equivalents.

In an embodiment, such as generally shown in fig. 1A and 1B, the track system 100 may include a support assembly 102 and/or one or more track assemblies/rail assemblies 104. The support assembly 102 and/or the track assembly 104 may include and/or be connected to an electrical system (e.g., of the vehicle 108), which may include a controller and/or a power source.

In an embodiment, such as generally shown in fig. 1A and 1B, the track assembly 104 may be coupled to the mounting surface 106 (e.g., a floor of the vehicle 108) and/or disposed in the mounting surface 106 (e.g., a floor of the vehicle 108), and may facilitate selectively coupling one or more support assemblies 102 to the mounting surface 106. The track assembly 104 may facilitate adjustment of one or more support assemblies 102, for example, relative to a mounting surface 106 and/or within a vehicle 108. In an example, the track system 100 may include several track assemblies 104, and the track assemblies 104 may be configured to engage corresponding portions of the support assemblies 102. Several track assemblies 104 may be connected to a portion of the mounting surface 106 (e.g., floor, wall, ceiling, etc.), may extend parallel to one another, and/or may be offset from one another in a lateral direction/transverse direction (e.g., Y-direction), such that the track assemblies 104 may be generally/substantially aligned with respective outer sides of the support assemblies 102.

For embodiments, such as generally shown in fig. 2, the track assembly 104 may include an outer track 120 and/or an inner track 150. The outer rail 120 and/or the inner rail 150 may be elongate members extending generally in the X-direction (e.g., longitudinal direction). The outer rail 120 and/or the inner rail 150 may facilitate movement and/or adjustment of the support assembly 102 and/or the support member 200 along the rail assembly 104. For example, and without limitation, the support member 200 may roll along a top surface of the outer rail 120 via one or more rolling members 220, and/or the support member 200 may selectively engage the outer rail 120 and/or the inner rail 150 to selectively limit/control relative movement between the support assembly 102 and the rail assembly 104. The outer rail 120 and/or the inner rail 150 may comprise one or more of a variety of materials. For example, and without limitation, the outer rail 120 may comprise a first material (e.g., aluminum), the first material may be relatively light, and/or the inner rail 150 may comprise a second material (e.g., steel), which may be relatively strong compared to the first material.

For an embodiment, such as generally shown in fig. 2, the outer rail 120 may have a rail base portion 122 and two rail wall portions (e.g., a first rail wall portion 124 and a second rail wall portion 126) that protrude from the rail base portion 122 to form a generally U-shaped cross-section in the Y-Z plane (e.g., in a plane perpendicular to the X-direction). The U-shaped cross-section may define a track receiver 130, the track receiver 130 configured to receive and/or at least temporarily retain a portion of the support assembly 102. The first rail lip/wing 132 and the second rail lip/wing 134 may protrude inwardly from the first rail wall portion 124 and the second rail wall portion 126, respectively, toward each other. The rail opening 128 may be defined between two rail lips 132, 134. A portion of the support assembly 102 may be inserted into the rail opening 128 and selectively retained within the rail receiver 130. The outer track 120 may include a first rolling portion 136 and/or a second rolling portion 138, and the first rolling portion 136 and/or the second rolling portion 138 may be configured to engage one or more rolling members 220 of the support member 200. The first rolling portion 136 may be disposed on the first rail lip 132 and/or adjacent to the first rail lip 132 (e.g., at or near the top surface of the outer rail 120). The second rolling portion 138 may be disposed on the second rail lip 134 and/or adjacent to the second rail lip 134. The first rolling portion 136 and/or the second rolling portion 138 may be configured as ridges, for example, ridges protruding from the track assembly 104 in the Z-direction, and/or may extend in the X-direction substantially along part or all of the length of the outer track 120.

For embodiments, such as generally shown in fig. 2 and 3, the inner rail 150 may be partially and/or fully disposed within the rail receiver 130. The inner rail 150 may be disposed on the rail base portion 122 and/or one or more rail wall portions 124, 126 of the outer rail 120 and/or connected (e.g., secured) to the rail base portion 122 and/or one or more rail wall portions 124, 126 of the outer rail 120. The inner rail 150 may, for example, comprise a generally L-shaped cross-section. The inner rail 150 can include a hook portion 152, and the hook portion 152 can be disposed adjacent the first rail wall portion 124 and/or the first rail lip 132 and/or extend adjacent the first rail wall portion 124 and/or the first rail lip 132.

For an embodiment, such as generally shown in fig. 2 and 3, the track assembly 104 may include one or more toothed portions 154 (e.g., racks) that the toothed portions 154 are configured to engage the regulator pinion 250 of the regulator assembly 230. The toothed portions 154 may each include one or more orbital teeth 156. The toothed portion 154 may extend generally in the X-direction, for example, along a portion or the entire length of the inner rail 150. One or more (e.g., all) of the track teeth 156 may be arranged one after the other and/or extend in alignment with each other in the X-direction. The rail teeth 156 may extend and/or protrude from the toothed portion 154 generally in the Z-direction (e.g., extend and/or protrude downwardly in the Z-direction toward the mounting surface 106). The toothed portion 154 may be disposed within the track receptacle 130 and/or may be disposed on an underside (undeside) of the track assembly 104. The toothed portion 154 may be connected to the outer rail 120 and/or the inner rail 150 and/or formed as part of the outer rail 120 and/or the inner rail 150. For example, and without limitation, the toothed portion 154 may be connected to the inner rail 150 and/or integrally formed with the inner rail 150, such as at or near the distal end of the hook portion 152. The tooth portion 154 and/or the rail tooth 156 may be disposed adjacent to and/or generally aligned with (e.g., in the Z-direction) an edge of the first rail lip 132 that at least partially defines the rail opening 128.

In an embodiment, such as generally shown in fig. 2, the track assembly 104 may include one or more electrical conductors 160 (e.g., bus bars), the electrical conductors 160 being configured to selectively contact and/or engage (e.g., electrically connect) one or more contacts of the support assembly 102. For example, the conductor 160 may be an elongated member extending in the X-direction and/or may have a generally U-shaped cross-section that is open in the Y-direction (e.g., transverse direction). Conductors 160 may be operably connected to a controller and/or a power source. The conductor 160 may be connected to the first track wall portion 124 and/or the second track wall portion 126 of the outer track 120 and/or another portion of the track assembly 104. The conductor 160 may be connected to the track assembly 104 via an insulator 170, and the insulator 170 may be configured to electrically insulate/isolate the conductor 160 from other portions of the track assembly 104. The insulator 170 may be an elongated body that may extend in the X-direction and/or may be configured to receive and/or retain one or more conductors 160.

For an embodiment, such as generally shown in fig. 1A, 1B, 4, 12A, and 12B, the support assembly 102 may include a support member 200. The support assembly 102 and/or the support member 200 can be adjusted and/or moved along the track assembly 104 (e.g., in the X-direction) manually and/or via the adjuster assembly 230. The support member 200 may be configured to be coupled to the track assembly 104 and removed from the track assembly 104 (e.g., in a vertical/Z direction), such as at a plurality of locations along the track assembly 104. For example, and without limitation, support member 200 may include, be coupled to, and/or support a seat (e.g., a vehicle seat) and/or one or more other components (e.g., a console, cargo rack, etc.). The support assembly 102, support member 200, and/or one or more components connected thereto may include one or more electrical components (e.g., a controller, a power source, a seat heater, an airbag, a fan, etc.). For example, the support member 200 may be configured as a base, leg, and/or support structure.

For embodiments, such as generally shown in fig. 1A, 1B, 4, 12A, and 12B, the support member 200 may include one or more electrical connectors 210, which one or more electrical connectors 210 may be configured to selectively connect with the track assembly 104. The electrical connector 210 may be configured to selectively electrically connect with the track assembly 104, such as with a conductor 160 (e.g., a bus bar) of the track assembly 104. For example, one or more contacts of the electrical connector 210 may be rotated into and out of contact with one or more conductors 160. The electrical connection between the electrical connector 210 and the conductor 160 may allow power and/or one or more signals (e.g., control signals, sensor data signals, etc.) to be provided to the support member 200 (e.g., electrical components) and/or allow power and/or one or more signals (e.g., control signals, sensor data signals, etc.) to be received from the support member 200 (e.g., electrical components).

For embodiments, such as generally shown in fig. 1A, 1B, 4, 12A, and 12B, the support member 200 may include one or more rolling members 220. The rolling members 220 may be configured to engage the first rolling portion 136 and/or the second rolling portion 138 of the track assembly 104 and/or to roll along the first rolling portion 136 and/or the second rolling portion 138 of the track assembly 104. The support member 200 may be configured to move along the track assembly 104 at least partially via one or more rolling members 220 (e.g., rolling members 220A, 220B). In an embodiment, the rolling members 220 may be configured to support at least a portion of the support assembly 102. The rolling members 220 may rotate as the support assembly 102 moves along the track assembly 104. The rolling member 220 may be rotatably connected to the body of the support member 200. For example, but not limited to, the first rolling member 220A may be rotatably connected at or near a first end of the support member 200 and/or the second rolling member 220B may be rotatably connected at or near a second end of the support member 200. One or more rolling members 220 (e.g., a first rolling member 220A and a second rolling member 220B) may be connected to the same lateral side (lateral side) of the support member 200. In such embodiments, the first rolling member 220A and the second rolling member 220B may both engage and/or roll along the same rolling portion (e.g., the first rolling portion 136, the second rolling portion 138, etc.). Additionally and/or alternatively, the rolling member 220 may be rotatably coupled on an opposite side of the regulator assembly 230 relative to the Y-direction such that the rolling member 220 may roll along the first rolling portion 136 and another rolling member 220 may roll along the second rolling portion 138.

For embodiments, such as generally shown in fig. 1A, 1B, 4, 12A, and 12B, the support member 200 may include an adjuster assembly 230, the adjuster assembly 230 configured to facilitate adjustment of the position (e.g., in the X-direction) of the support member 200 relative to the track assembly 104. For example, but not limiting of, the electric motor 232 of the adjuster assembly 230 may rotate the adjuster pinion 250, and the adjuster pinion 250 may engage the toothed portion 154 to adjust the position of the support member 200 relative to the track assembly 104, such as in the X-direction. The electric motor 232 may be disposed within the regulator assembly 230 and/or operatively connected to the regulator pinion 250 such that the regulator pinion 250 may be rotated by the electric motor 232. Additionally and/or alternatively, the electric motor 232 may be disposed within the support assembly 102 and/or operatively connected to one or more support members 200. For example, and without limitation, the support assembly 102 may include (i) two or more support members 200 arranged opposite each other (e.g., generally relative to the Y-direction) and/or (ii) an electric motor 232 arranged between the two support members 200 and connected (e.g., via respective flexible shafts (flex shafts)) to the regulator assembly 230 of one or both of the two support members 200, which in some examples may be curved and/or bent. In some cases, a transmission may connect the motor 232 to the regulator assembly 230.

For embodiments, such as generally illustrated in fig. 1A, 1B, 4, 12A, and 12B, the regulator assembly 230 may be adjustably connected to the body of the support member 200 such that the regulator assembly 230 may move and/or float, e.g., in the Z-direction, relative to the body of the support member 200. Additionally and/or alternatively, the adjuster assembly 230 may rotate relative to the support member 200 and/or the track assembly 104, such as about the adjuster axis 240. The regulator assembly 230 may be operably connected to the electrical components of the support member 200, such as by one or more wires. For example, but not limited to, electrical components may power the electric motor 232 of the regulator assembly 230 and/or control operation of the electric motor 232.

In an embodiment, such as generally shown in fig. 1B, the regulator assembly 230 may include one or more portions (e.g., tabs (tabs) 236) configured to contact and/or engage the slider 270 of the support member 200. For example, and without limitation, the protrusion 236 may be configured as a protrusion extending generally in the Z-direction (e.g., downward in the Z-direction toward the mounting surface 106). Additionally and/or alternatively, the protrusion 236 may be configured as a surface, edge, slot, recess, body, and/or any other structure configured to engage the slider 270.

For embodiments, such as generally shown in fig. 1A, 1B, 4, 12A, and 12B, the regulator assembly 230 may include one or more portions (e.g., flanges 242) configured to contact and/or engage the actuation body 330. The adjuster assembly 230 may be adjustable, such as in a generally Z-direction, by a flange 242. The flange 242 may extend generally in the Y-direction and/or may be disposed on the same side or an opposite side of the regulator assembly 230 relative to the regulator pinion 250. Additionally and/or alternatively, the flange 242 may be configured as a surface, edge, slot, groove, body, and/or any other structure configured to engage the actuation body 330.

For an embodiment, such as generally shown in fig. 4, 12A, and 12B, the support member 200 may include an adjuster pinion 250. The adjuster pinion 250 may be configured to engage the toothed portion 154 of the track assembly 104. The regulator pinion 250 may rotate about a regulator pinion axis 252, and the regulator pinion axis 252 may extend generally in the Y-direction (e.g., perpendicular to the longitudinal direction of the track assembly 104). The regulator pinion 250 may include one or more regulator pinion teeth 254, the one or more regulator pinion teeth 254 configured to engage one or more rail teeth 156 of the toothed portion 154. The regulator pinion teeth 254 may extend radially outward from the regulator pinion 250 relative to the regulator pinion axis 252. The regulator pinion 250 may be connected to the electric motor 232 directly and/or indirectly (e.g., via a flexible shaft). The electric motor 232 may be operably connected to the regulator pinion 250 such that the regulator pinion 250 is rotatable by the electric motor 232.

For embodiments, the adjuster pinion 250 (and the adjuster assembly 230, at least in some configurations) may be adjustable to engage and/or disengage the toothed portion 154 of the track assembly 104 (e.g., with or without the adjuster pinion teeth 254 engaging the track teeth 156). The adjuster pinion 250 and/or the adjuster assembly 230 may be adjusted generally downward in the Z-direction to disengage the track assembly 104, for example, and/or may be adjusted generally upward in the Z-direction to engage the track assembly 104. For example, the adjuster pinion 250 and/or the adjuster assembly 230, when disengaged from the toothed portion 154, may be adjusted (e.g., moved, slid, rotated) laterally in a generally Y-direction into and/or out of Z-direction alignment with the toothed portion 154 of the track assembly 104.

For embodiments, such as generally shown in fig. 1B and 8, the support member 200 may include a slider 270, and the slider 270 may be adjustable, movable, slidable, etc., for example, in a direction generally parallel to the X-direction. The slider 270 may be disposed between the top and bottom of the regulator assembly 230. The slider 270 may be configured to engage and/or facilitate adjustment of the adjuster assembly 230 and/or anchors 400, 400'. Additionally and/or alternatively, the slider 270 may be configured to engage and/or facilitate adjustment (e.g., rotation) of the electrical connector 210 to engage one or more contacts with a corresponding conductor 160. In an example, when the support assembly 102 is disposed on the track assembly 104 and/or connected to the track assembly 104, the slider 270 of the support assembly 102 and the toothed portion 154 of the track assembly 104 may be disposed on opposite sides of the track opening 128 relative to the Y-direction (e.g., the slider 270 may be disposed proximate/adjacent to the second track lip 134 and the toothed portion 154 may be disposed proximate/adjacent to the first track lip 132).

For embodiments, such as generally shown in fig. 1B and/or 8, the slider 270 may include a slider body 272, and the slider body 272 may be configured as an elongated member and/or may extend generally in the X-direction. The slider 270 may include a slider protrusion 274, and the slider protrusion 274 may extend generally in the Z-direction. The slider protrusion 274 may be disposed on the slider body 272 and/or connected to the slider body 272. The slider 270 and/or the slider protrusion 274 may include a guide surface 282, the guide surface 282 being configured to engage, contact, and/or abut the regulator assembly 230 (e.g., the tab 236). The guide surface 282 may extend generally in the X-direction and/or may generally face in the Y-direction. The guide surface 282 may include a first end 284, a middle section 286, and/or a second end 288.

For embodiments, when the adjuster pinion 250 and/or the adjuster assembly 230 are not aligned in the Z-direction with the toothed portion 154 of the track assembly 104, the tab 236 may be disposed adjacent the first end 284 of the guide surface 282 and/or in contact with the first end 284 of the guide surface 282, and/or may extend obliquely relative to the slider protrusion 274. The adjuster assembly 230 may be biased, for example, generally in the Y-direction (e.g., about the adjuster axis 240) such that the tab 236 is biased into contact with the slider protrusion 274 and/or the guide surface 282. When the adjuster pinion 250 and/or the adjuster assembly 230 are aligned in the Z-direction with the toothed portion 154 of the track assembly 104 and disengaged from the toothed portion 154 of the track assembly 104 (see, e.g., fig. 12B), the protrusion 236 may be disposed between the first end 284 of the guide surface 282 and the intermediate section 286 and/or may extend generally parallel to the slider protrusion 274. When the adjuster pinion 250 and/or the adjuster assembly 230 are engaged with the toothed portion 154 of the track assembly 104, as generally shown in fig. 12A, the protrusion 236 may be disposed adjacent to the middle section 286 of the guide surface 282 and/or in contact with the middle section 286 of the guide surface 282, and/or may extend generally parallel to the slider protrusion 274.

For embodiments, such as generally shown in fig. 1B and 8, the slider 270 may include one or more slider channels (e.g., a first slider channel 298, a second slider channel 298 ') configured to engage and/or adjust one or more anchors 400, 400'. The slide channel 298 may be defined by one or more slide walls (e.g., a first slide wall 300 and a second slide wall 302) that may be disposed on the slide body 272 and/or connected to the slide body 272. The slider walls 300, 302 may extend generally in the X-direction along the slider body 272 and/or may extend parallel to one another. The slide channel 298 may be configured to receive an anchor tab 442 of a corresponding anchor 400. For example, and without limitation, the anchor protrusions 442 may be inserted into the slide channel 298 (e.g., generally downward in the Z-direction), may engage, contact, and/or abut one or more slide walls 300, 302, and/or may be adjustable (e.g., slidable) along one or more slide walls 300, 302 within the slide channel 298. The slide channel 298 may include a first section 298A, a second section 298B, and/or a third section 298C. The second section 298B may be disposed between the first section 298A and the third section 298C. The first and third sections 298A, 298C may be arranged offset from one another (e.g., generally in the Y-direction) such that the second section 298B extends obliquely to the X-direction and/or the Y-direction, which may facilitate adjusting (e.g., generally in the Y-direction) the anchor 400 into and/or out of Z-direction alignment with the toothed portion 154 of the track assembly 104. The slider walls 300, 302 may extend from the slider body 272 generally in the Z-direction. A portion of the slider walls 300, 302 (e.g., a portion of the slider walls 300, 302 defining the first section 298A and/or a portion of the slider walls 300, 302 defining the third section 298C) may extend generally farther from the slider body 272 in the Z-direction than another portion of the slider walls 300, 302 (e.g., a portion of the slider walls 300, 302 defining the second section 298B), which may facilitate (e.g., generally in the Z-direction) adjusting the anchor 400 into and/or out of engagement with the toothed portion 154 of the track assembly 104. The slider 270 may include a slider recess 304, which slider recess 304 may be configured to receive at least a portion of the anchor protrusion 442, which may facilitate adjustment of the anchor 400 into and/or out of engagement with the track assembly 104. The slide recess 304 may be disposed adjacent and/or near the slide channel 298 (e.g., the third section 298C).

In some examples, the slider 270 may include a second slider channel 298', a second channel first section 298A', a second channel second section 298B ', a second channel third section 298C', a first slider wall 300', a second slider wall 302', and/or a slider recess 304 'configured to engage a second anchor 400', some or all of which may be configured in the same or similar manner as corresponding features of the first slider channel 298. In other examples, the first slide channel 298 and the second slide channel 298' may be configured differently from one another.

For embodiments, such as generally shown in fig. 1B and/or 8, the slider 270 may include one or more toothed slider portions 276 (e.g., racks), which toothed slider portions 276 may be configured to engage a slider pinion 280 of the support member 200, which slider pinion 280 may include one or more slider pinion teeth 294. The toothed slider portion 276 may include one or more slider teeth 278. The toothed slider portion 276 may extend generally in the X-direction. One or more (e.g., all) of the slider teeth 278 may be arranged one after the other and/or aligned with each other in the X-direction. The slider teeth 278 may extend and/or protrude from the slider 270 and/or the toothed slider portion 276 generally in the Z-direction (e.g., extend and/or protrude upwardly away from the mounting surface 106 in the Z-direction).

For an embodiment, such as generally shown in fig. 1A and 1B, the support member 200 may include a slider pinion 280, the slider pinion 280 configured to engage the toothed slider portion 276. The slider pinion 280 may include one or more slider pinion teeth 294 configured to engage the one or more slider teeth 278. The slider pinion 280 may rotate about a slider pinion axis 290, the slider pinion axis 290 may extend generally in the Y-direction and/or may be generally coaxial with the engagement cam axis 314. The slider pinion 280 may be disposed on the engagement body 310 and/or the actuation shaft 292, connected to the engagement body 310 and/or the actuation shaft 292, and/or engaged with the engagement body 310 and/or the actuation shaft 292. The slider pinion 280 may be rotated by rotating the actuation shaft 292, rotating the engagement body 310, and/or adjusting the slider 270 (e.g., generally in the X-direction). Additionally and/or alternatively, the slider pinion 280 may be configured to move independently of the actuation shaft 292 and/or the engagement body 310 (e.g., the slider pinion 280 may rotate without causing the actuation shaft 292 and/or the engagement body 310 to rotate, and/or the actuation shaft 292 may rotate without rotating the slider pinion 280). In at least some instances, the rotating slider pinion 280 may rotationally engage the body 310, e.g., along with the slider pinion 280 and rotate relative to the actuation shaft 292.

For embodiments, such as generally shown in fig. 1B, the slider 270 may be actuated/moved in one or more of a variety of ways. For example, the slider 270 may be actuated by adjusting (e.g., rotating) the lever 212 of the support member 200, which lever 212 may be engaged with the slider 270 and/or connected to the slider 270. The slider 270 may be actuated, for example, by an actuation shaft 292 and/or a slider pinion 280 coupled to the actuation shaft 292, the slider pinion 280 may be engaged with the toothed slider portion 276 of the slider 270. Additionally or alternatively, the user may move the slider 270 directly and/or through a handle/joystick/link.

For embodiments, such as generally shown in fig. 1A, 12A, and 12B, the support member 200 may include an engagement body 310, which engagement body 310 may be configured to facilitate adjustment of one or more anchors 400, 400' into and/or out of engagement with the toothed portion 154 of the track assembly 104. The engagement body 310 may rotate about an axis extending generally in the Y-direction (e.g., the engagement cam axis 314). The engagement body 310 may be operably connected to one or more engagement members 350, 350 'such that rotating the engagement body 310 adjusts the engagement members 350, 350' generally in the X-direction. The engagement body 310 may be disposed on the actuation shaft 292, the engagement cam 312, and/or the slider pinion 280, connected to the actuation shaft 292, the engagement cam 312, and/or the slider pinion 280, and/or engaged with the actuation shaft 292, the engagement cam 312, and/or the slider pinion 280. The engagement body 310 may be rotated by rotating the engagement cam 312 (e.g., by rotating the actuation shaft 292) and/or rotating the slider pinion 280 (e.g., by adjusting the slider 270 with the lever 212). Additionally and/or alternatively, in at least some instances, the engagement body 310 may be configured to rotate independently of the actuation shaft 292, the engagement cam 312, and/or the slider pinion 280. For example, rotation of the slider pinion 280 (e.g., by longitudinal movement of the slider 270) may result in rotation of the engagement body 310 relative to the actuation shaft 292 and/or the engagement cam 312, which may move the anchors 400, 400' without moving the adjuster assembly 230 (e.g., to maintain the adjuster assembly 230 in the disengaged position).

For embodiments, such as generally shown in fig. 1A, 12A, and 12B, the support member 200 may include an engagement cam 312, which engagement cam 312 may be configured to facilitate adjusting the adjuster assembly 230 and/or the adjuster pinion 250 into and/or out of engagement with the track assembly 104. The engagement cam 312 may rotate about an engagement cam axis 314, and the engagement cam axis 314 may extend generally in the Y-direction. For example, the engagement cam 312 may be adjustable (e.g., rotatable) to a first position (see, e.g., fig. 12B) and/or a second position (see, e.g., fig. 12A). Engaging cam 312 may include engaging cam hub 316 and/or engaging cam projection 318. Engagement cam protrusion 318 may extend radially from engagement cam hub 316 relative to engagement cam axis 314. The engagement cam 312 may be disposed on the actuation shaft 292, connected to the actuation shaft 292, and/or engaged with the actuation shaft 292 such that, for example, the engagement cam 312 may be rotated by rotating the actuation shaft 292. The engagement cam 312 may be connected to the engagement body 310 and/or engaged with the engagement body 310.

For embodiments, such as generally shown in fig. 1A and 1B, the engagement body 310, the engagement cam 312, and/or the slider pinion 280 may be rotatably connected to the support member 200 (and/or a second support member 200 disposed opposite the first support member 200). In an example, the engagement body 310, and/or the slider pinion 280 may be connected to the actuation shaft 292 of the support member 200, and the actuation shaft 292 may be configured to rotate the engagement body 310, the engagement body 312, and/or the slider pinion 280 about the engagement cam axis 314. For example, and without limitation, the actuation shaft 292 may be configured to simultaneously engage and/or rotate the slider pinion 280 and/or engage the cam 312. For example, the actuation shaft 292 may be actuated manually and/or by a powered actuator (e.g., an electric motor).

For an embodiment, such as generally shown in fig. 1A, 12A, and 12B, the support member 200 may include an actuation body 330. The actuation body 330 may have an actuation body axis 332 and/or may be rotatable about the actuation body axis 332, which actuation body axis 332 may extend generally in the Y-direction. For example, the actuation body 330 may include a first actuation portion 334, the first actuation portion 334 configured to engage, contact, and/or abut the regulator assembly 230, such as the flange 242. The actuation body 330 can include a second actuation portion 336, the second actuation portion 336 being configured to engage, contact, and/or abut the engagement cam 312 (e.g., the engagement cam protrusion 318). The actuation body 330 may include a third actuation portion 338, which third actuation portion 338 may engage and/or be connected to a biasing member 344 (e.g., a spring). Additionally and/or alternatively, the biasing member 344 may be connected to the body of the support member 200, such as at an end opposite the actuation body 330. The biasing member 344 may bias the actuation body 330 about the actuation body axis 332, which may bias the second actuation portion 336 into contact with the engagement cam 312.

For embodiments, such as generally shown in fig. 1A, 4, 12A, and/or 12B, the support member 200 may include one or more engagement members 350, the engagement members 350 configured to engage corresponding anchor cams 470. The engagement member 350 may be an elongated member that may extend generally in the X-direction. The engagement member 350 may include an engagement member toothed portion 352 (e.g., a rack), and the engagement member toothed portion 352 may be configured to engage an anchor cam tooth 478 of an anchor cam 470. The engagement member toothed portion 352 may generally extend in the X-direction and/or may include one or more engagement member teeth 354, which engagement member teeth 354 may be arranged one after the other and/or aligned with each other in the X-direction. The engagement member teeth 354 may extend and/or protrude from the engagement member 350 and/or the engagement member toothed portion 352 generally in the Z-direction (e.g., downward in the Z-direction toward the mounting surface 106). The engagement member 350 may be operatively and/or adjustably connected to the engagement body 310, such as on a side of the engagement body 310 opposite the engagement cam 312. For example, but not limiting of, the engagement member 350 may adjustably engage a slot or recess of the engagement body 310, which may be inclined toward the engagement cam axis 314 such that rotation of the engagement body 310 adjusts, moves, etc., the engagement member 350 toward and/or away from the engagement cam axis 314. The engagement member 350 may be operatively and/or adjustably connected to the anchor cam 470. For example, and without limitation, the engagement member 350 may be adjusted, moved, slid, etc., generally in the X-direction by the engagement body 310, which may cause the engagement member toothed portion 352 to engage and/or rotate the anchor cam 470.

In an embodiment, the support member 200 may include a first engagement member 350 configured to engage a first anchor cam 470 of a first anchor 400 and a second engagement member 350' configured to engage a second anchor cam 470' of a second anchor 400 '. The second engagement member 350' may include engagement member toothed portions 352' and/or engagement member teeth 354', some or all of which may be configured in the same or similar manner as corresponding features of the first engagement member 350. A cross-sectional view of the engagement members 350, 350' (e.g., in a plane perpendicular to the Y-direction) of the support member 200 is generally shown in fig. 4 to provide a clear view of the engagement between the engagement members 350, 350' and the anchor cams 470, 470 '.

For embodiments, such as generally shown in fig. 1A, 1B, and 4-14B, the support member 200 may include one or more anchors 400 configured to engage and/or connect, secure, mount, or otherwise connect the support member 200 to the track assembly 104. Anchor 400 may be adjustable generally in the Z-direction, may be adjustable generally in the Y-direction, and/or may be rotatable about an anchor axis 402, and anchor axis 402 may extend generally in the X-direction. The anchor axis 402 may be disposed at or near a first end/tip 404 of the anchor 400, and the first end/tip 404 of the anchor 400 may be disposed opposite a second end/tip 406 of the anchor 400. Anchor 400 may include an anchor body 410, a toothed anchor portion 412 (e.g., a rack), and/or an anchor member 414. Toothed anchor portion 412 and/or anchor member 414 may be connected to second end 406 of anchor 400. The anchor member 414 may be connected to the toothed anchor portion 412 such that, for example, the toothed anchor portion 412 is disposed between the anchor body 410 and the anchor member 414. Anchor body 410, toothed anchor portion 412, and/or anchor member 414 may collectively form hooked portion 408 of anchor 400. In examples, such as those in which anchor 400 is adjustable via slide channel 298 (see, e.g., fig. 5A-8 and 10-11B), anchor 400 may be biased into engagement with slide channel 298 (e.g., generally downward in the Z-direction) such that when slide 270 is moved and anchor protrusions 440 and/or anchor protrusions 442 are aligned with second section 298B, anchor 400 may be moved downward to a disengaged position. In other examples, such as those in which anchor 400 is adjustable by engaging body 310 (see, e.g., fig. 1A, 1B, 4, 8-9C, and 12A-14B), anchor 400 may be biased generally upward in the Z-direction (e.g., toward the engaged position), in the Y-direction toward toothed portion 154, and/or about anchor axis 402, such as by anchor biasing member 456. The anchor biasing member 456 (e.g., a spring) may be connected to, disposed on, and/or engaged with a portion of the engagement support member 200 (e.g., the body of the support member 200) and/or a portion of the anchor 400 (e.g., the body of the support member 200).

For embodiments, the hooked portion 408 of the anchor 400 formed by the anchor body 410, the toothed anchor portion 412, and/or the anchor member 414 may provide better space efficiency than an anchor 400 formed from a single piece (e.g., having a portion bent into a U-shaped configuration). For example, bending a piece of metal into a U-shape may result in rounded portions and/or a minimum radius, which may increase the width of the hook portion 408 in the Y-direction and/or impair the connection/formation of the anchor teeth 416. The hook portion 408 having a greater width may require further rotation to engage and/or disengage the track assembly 104, which may use more space and/or a longer actuation distance, one or both of which may increase the overall size and/or weight of the track system 100.

For embodiments, anchor 400 may include an anchor adjustment portion 444, and anchor adjustment portion 444 may be configured to engage anchor cam projection 480, which may facilitate adjustment of anchor 400 generally in the Z-direction (see, e.g., fig. 13A and 13B). Anchor 400 may include an anchor opening 446, which anchor opening 446 may be configured to at least partially receive an anchor cam base 482 (see, e.g., fig. 13A and 13B). The anchor 400 may include a ramped protuberance 448, which ramped protuberance 448 may be configured to engage the anchor cam protuberance 476 to limit and/or prevent movement/adjustment of the anchor 400 generally in the Z-direction and/or to cause the anchor 400 to be ramped/rotated about an axis that may extend generally in the Y-direction (see, e.g., fig. 14A and 14B). The anchor adjustment portion 444 and/or the angled protrusion 448 may extend from the anchor 400 (e.g., the anchor body 410) generally perpendicular to the anchor 400 and/or may be disposed adjacent to/near the anchor opening 446. Additionally and/or alternatively, anchor adjustment portion 444 and/or sloped protrusions 448 can be configured as surfaces, edges, bodies, and/or any other structure configured to engage anchor cam protrusion 480 and/or anchor cam protrusion 476.

For embodiments, such as generally shown in fig. 4-14B, the toothed anchor portion 412 may be configured to engage the toothed portion 154 of the track assembly 104. The toothed anchor portion 412 may be an elongated (e.g., planar) member and/or may include one or more anchor teeth 416. The toothed anchor portion 412 may extend generally in the X-direction. One or more (e.g., all) of the anchor teeth 416 may be arranged one after the other in the X-direction and/or aligned with each other in the X-direction. The anchor teeth 416 may extend and/or protrude generally in the Z-direction from the anchor 400 and/or the toothed anchor portion 412 (e.g., extend and/or protrude upwardly in the Z-direction away from the mounting surface 106). The toothed anchor portion 412 may be configured as a separate component from the anchor body 410 and/or the anchor member 414 (see, e.g., fig. 5A-8). Additionally and/or alternatively, the toothed anchor portion 412 may be integrally formed with the anchor body 410 and/or the anchor member 414 and/or protrude from the anchor body 410 and/or the anchor member 414. For example, as generally shown in fig. 9A-9C, the toothed anchor portion 412 may be stamped into the anchor body 410 and/or the anchor member 414 and thus configured as a stamped portion 418 of the anchor body 410 and/or the anchor 400.

For embodiments, such as generally shown in fig. 4-14B, the anchor member 414 may be configured to facilitate and/or maintain alignment (e.g., generally in the Y-direction) and/or engagement of the toothed anchor portion 412 and the toothed portion 154 of the track assembly 104. The anchor member 414 may be an elongated (e.g., planar) member that extends generally in the X-direction. In some examples, anchor member 414 may extend generally upward in the Z-direction beyond toothed anchor portion 412 and/or extend farther than toothed anchor portion 412 such that a gap 420 (e.g., space) is defined between anchor member 414 and anchor body 410 (e.g., generally in the Y-direction). Additionally and/or alternatively, gap 420 may be defined and/or disposed above toothed anchor portion 412 relative to the Z-direction. The gap 420 may be configured to at least partially receive the toothed portion 154 of the track assembly 104 and/or guide the toothed portion 154 of the track assembly 104 into engagement with the toothed anchor portion 412, e.g., generally in the Z-direction.

In at least some examples, the anchor recesses 422A, 422B may extend into the anchor body 410, the toothed anchor portion 412, and/or the anchor member 414 (e.g., generally in the Y-direction) and/or extend through the anchor body 410, the toothed anchor portion 412, and/or the anchor member 414 (e.g., generally in the Y-direction). One or more anchor connectors 424A, 424B (e.g., pins, bolts, screws, fasteners, etc.) may be disposed in the corresponding anchor recesses 422A, 422B and/or engage the corresponding anchor recesses 422A, 422B to connect the anchor body 410, the toothed anchor portion 412, and/or the anchor member 414 to one another.

For embodiments, such as generally shown in fig. 7, anchor 400 may include one or more anchor receptacles 430A, 430B, 430C, 432A, 432B and/or one or more anchor protrusions 434A, 434B, 434C, 436A, 436B. To connect the anchor body 410, the toothed anchor portion 412, and/or the anchor member 414 to one another, for example, the first anchor protrusions 434A, 434B, 434C may be configured to engage the corresponding first anchor receptacles 430A, 430B, 430C, and/or the second anchor protrusions 436A, 436B may be configured to engage the corresponding second anchor receptacles 432A, 432B. The first anchor receptacles 430A, 430B, 430C may be disposed in the anchor body 410. The second anchor receptacles 432A, 432B may be disposed in the anchor member 414. The first anchor protrusions 434A, 434B, 434C and/or the second anchor protrusions 436A, 436B may be disposed on (e.g., on opposite sides relative to) and/or connected to (e.g., on opposite sides relative to) the toothed anchor portion 412 and/or may be differently configured from one another to facilitate, for example, proper assembly of the anchor 400. Additionally and/or alternatively, one or more anchor protrusions 434A, 434B, 434C, 436A, 436B may be disposed on the anchor body 410 and/or the anchor member 414. The anchor protrusions 434A, 434B, 434C, 436A, 436B disposed on the anchor body 410 may, for example, be configured to engage corresponding anchor receptacles 430A, 430B, 430C, 432A, 432B disposed in the toothed anchor portion 412 and/or the anchor member 414. The anchor protrusions 434A, 434B, 434C, 436A, 436B disposed on the anchor member 414 may, for example, be configured to engage corresponding anchor receptacles 430A, 430B, 430C, 432A, 432B disposed in the toothed anchor portion 412 and/or the anchor body 410. One or more anchor protrusions 434A, 434B, 434C, 436A, 436B may be configured as separate, individual components or may be integrally formed with anchor 400 (e.g., toothed anchor portion 412).

For embodiments, such as generally shown in fig. 5A-8, 10-11B, and 13A-14B, anchor 400 may include an anchor protrusion 440, which anchor protrusion 440 may be configured to engage slider 270. Anchor protrusions 440 may extend from anchor 400 (e.g., anchor body 410) generally in the Y-direction. The anchor protrusions 440 may include anchor protrusions 442, and the anchor protrusions 442 may be configured to engage corresponding slide passages 298. Anchor protrusions 442 may be disposed on anchor protrusions 440 and/or connected to anchor protrusions 440, such as at or near an end of anchor protrusions 440 opposite anchor body 410. The anchor protrusions 442 may extend generally in the Z-direction, for example, from the anchor protrusions 440 (e.g., downwardly in the Z-direction toward the mounting surface 106).

For embodiments, such as generally shown in fig. 9A-9C, 12A, 12B, 14A, and 14B, the anchor 400 may include a ramp portion 450 configured to engage a corresponding anchor cam 470. Ramp portion 450 may protrude from anchor 400 (e.g., anchor body 410) generally in the Y-direction. Ramp portion 450 may extend along anchor 400 in a curved manner, such as from a first ramp end 452 to a second ramp end 454. The first ramp end 452 may be disposed above the second ramp end 454 relative to the Z-direction, and/or the second ramp end 454 may protrude further from the anchor 400 in the Y-direction than the first ramp end 452 such that the ramp portion 450 is inclined generally downward in the Z-direction and generally away from the anchor 400 in the Y-direction.

In an embodiment, the support member 200 may include a first anchor 400 and a second anchor 400'. The second anchor 400' may include a second anchor axis 402', a first end 404', a second end 406', a hooked portion 408', an anchor body 410', a toothed anchor portion 412', an anchor member 414', an anchor tooth 416', a gap 420', anchor recesses 422A ', 422B ', anchor connectors 424A ', 424B ', anchor protrusions 440', anchor protrusions 442', anchor adjustment portions, anchor openings, inclined protrusions, anchor biasing members, ramp portions 450', a first ramp end 452', and/or a second ramp end 454', some or all of which may be configured in the same or similar manner as corresponding features of the first anchor 400. For example, the first anchor axis 402 and the second anchor axis 402' may be substantially coaxial.

For embodiments, the anchors 400, 400' may be adjusted to an engaged position (see, e.g., fig. 4, 10, 11A, 12B, 13A, 14A) in which the anchors 400, 400' (e.g., the toothed anchor portions 412, 412 ') are engaged with the toothed portions 154 of the track assembly 104 (e.g., the anchor teeth 416, 416' are engaged with the track teeth 156) and/or a disengaged position (see, e.g., fig. 1A, 1B, 11B, 12A, 13B, 14B) in which the anchors 400, 400' (e.g., the toothed anchor portions 412, 412 ') are disengaged/disengaged from the toothed portions 154 of the track assembly 104 (e.g., the anchor teeth 416, 416' are not engaged with the track teeth 156). The disengaged position may include, for example, a misaligned position in which the anchor 400, 400 'is disengaged and misaligned (e.g., relative to the Z-direction) with the toothed portion 154 and/or an aligned position in which the anchor 400, 400' is disengaged and aligned (e.g., relative to the Z-direction) with the toothed portion 154. When in the misaligned position, anchors 400, 400' may be disposed and/or extended obliquely or perpendicular to the Z-direction. When in the aligned and/or engaged position, the anchors 400, 400' may be disposed generally parallel to the Z-direction. For example, anchors 400, 400' may be adjustable generally downward in the Z-direction toward the disengaged position, and/or may be adjustable generally upward in the Z-direction toward the engaged position. When the anchors 400, 400 'are disengaged from the toothed portion 154, for example, the anchors 400, 400' can be adjusted (e.g., moved, slid, rotated) generally laterally in the Y-direction toward the aligned position and/or the misaligned position.

For embodiments, such as when in a misaligned position (see, e.g., fig. 11B), the anchors 400, 400' may be inserted into the track assembly 104 and/or removed from the track assembly 104, such as inserted into the track receptacle 130 through the track opening 128 and/or removed from the track receptacle 130. When in the aligned position, the anchors 400, 400' may (i) limit and/or prevent removal of the support member 200 from the track assembly 104 (e.g., in the Z-direction), and/or (ii) facilitate adjustment of the support member 200 along the track assembly 104 (e.g., via the adjuster pinion 250, via manual movement of the support assembly 102 by a user, etc.). When the anchors 400, 400 'are in the engaged position (see, e.g., fig. 11A), the anchors 400, 400' may connect, secure, and/or mount the support assembly 102 and/or the support member 200 to the track assembly 104 such that X-directional movement, Y-directional movement, and/or Z-directional movement of the support member 200 relative to the track assembly 104 is limited and/or substantially prevented.

For an embodiment, when the anchors 400, 400' are in the disengaged position (see, e.g., fig. 12A), the adjuster assembly 230 may be engaged with the track assembly 104 such that the support member 200 is connected/secured to the track assembly 104 and/or adjustable along the track assembly 104, such as by operation of the electric motor 232, which may cause the adjuster pinion 250 to rotate about the adjuster pinion axis 252, which may cause the adjuster pinion teeth 254 to engage the toothed portion 154 of the track assembly 104, which may cause the support member 200 to move along the track assembly 104. Additionally and/or alternatively, when the anchors 400, 400' are in the misaligned position, the adjuster assembly 230 may be out of alignment with the Z-direction of the track assembly 104 and/or out of alignment with the Z-direction of the track assembly 104 such that the support member 200 may be removed from the track assembly 104 and/or inserted into the track assembly 104 at a plurality of positions along the track assembly 104. When the anchors 400, 400' are in the engaged position (see, e.g., fig. 12B), the adjuster assembly 230 may be disengaged from the track assembly 104, which may protect the adjuster assembly 230 (e.g., the adjuster pinion 250) from damage (at least to some extent) in the event of a collision and/or application of abnormal stresses to the support assembly 102 and/or the track assembly 104 (e.g., stresses that exceed those that occur during normal use and/or operation). For embodiments, the adjuster assembly 230 and/or the adjuster pinion 250 may default to an aligned position and/or the anchors 400, 400' may default to an engaged position.

For embodiments, such as generally shown in fig. 1A, 4, 12A, and 12B, the support member 200 may include anchor cams 470, and the anchor cams 470 may be configured to engage the respective anchors 400 and/or facilitate adjustment of the respective anchors 400. The anchor cam 470 may be rotatably connected to the support member 200. The anchor cam 470 may rotate about an anchor cam axis 472, and the anchor cam axis 472 may extend generally in the Y-direction. The anchor cam 470 may include an anchor cam hub 474 and/or an anchor cam projection 476. Anchor cam projection 476 may extend radially from anchor cam hub 474 relative to anchor cam axis 472. Anchor cam projections 476 may be configured to contact, abut, and/or engage ramp portions 450 of corresponding anchors 400. Anchor cam 470 may include an anchor cam protrusion 480, and anchor cam protrusion 480 may be connected to anchor cam base 482 and/or extend radially from anchor cam base 482. Anchor cam projection 480 may be configured to contact, abut, and/or engage anchor adjustment portion 444 of a corresponding anchor 400. Anchor cam base 482 extends at least partially through anchor opening 446 of anchor 400 (e.g., generally in the Y-direction). Anchor cam lobe 476 and anchor cam lobe 480 may be disposed at opposite ends of anchor cam base 482 and/or connected to opposite ends of anchor cam base 482 such that, for example, anchor cam lobe 476 and anchor cam lobe 480 may be disposed on opposite sides of anchor 400. The anchor cam 470 may include one or more anchor cam teeth 478, the anchor cam teeth 478 may extend radially relative to the anchor cam axis 472, and the anchor cam 470 may engage the engagement member toothed portion 352 of the corresponding engagement member 350 via the anchor cam teeth 478. In an example, the anchor cam 470 may be connected to the engagement member tooth 352 of the engagement member 350, which engagement member tooth 352 may be configured to rotate the anchor cam 470 about the anchor cam axis 472.

In an embodiment, anchor cam 470 may be configured such that when anchor 400 is disengaged from track assembly 104, anchor cam protrusion 480 may adjust anchor 400 generally downward in the Z-direction to disengage anchor 400 from toothed portion 154 of track assembly 104 (e.g., by engaging anchor adjustment portion 444) before anchor cam protrusion 476 adjusts anchor 400 generally in the Y-direction away from toothed portion 154 (e.g., by engaging ramp portion 450). Additionally and/or alternatively, the anchor cam 470 may be configured such that when engaging the anchor 400 with the track assembly 104, the anchor cam protrusion 476 may adjust the anchor 400 generally in the Y-direction toward the toothed portion 154 of the track assembly 104 and/or allow the anchor 400 to adjust generally in the Y-direction toward the toothed portion 154 of the track assembly 104 (e.g., by disengaging and/or applying a biasing force to the anchor biasing member 456) before the anchor cam protrusion 480 adjusts the anchor 400 generally upward in the Z-direction and/or allows the anchor 400 to be generally upward in the Z-direction to engage the anchor 400 with the toothed portion 154 (e.g., by disengaging and/or applying a biasing force to the anchor biasing member 456).

In an embodiment, the support member 200 may include a first anchor cam 470 configured to engage the first anchor 400 and a second anchor cam 470 'configured to engage the second anchor 400'. The second anchor cam 470' may include a second anchor cam axis 472', an anchor cam hub 474', an anchor cam projection 476', an anchor cam tooth 478', an anchor cam projection, and/or an anchor cam base, some or all of which may be configured in the same or similar manner as the corresponding features of the first anchor cam 470.

For an embodiment, such as generally shown in fig. 12B, when the engagement cam 312 is in the first engagement cam position, the regulator assembly 230 and/or the regulator pinion 250 may be disengaged from the track assembly 104 and/or the support member 200 may be secured (e.g., mounted) to the track assembly 104, and adjustment and/or removal of the support member 200 from the track assembly 104 may be restricted and/or prevented by the anchors 400, 400'. In the first engagement cam position, the second actuating portion 336 may be biased into contact with the engagement cam projection 318 (e.g., generally downward in the Z-direction), the first actuating portion 334 may (or may not) contact the adjuster assembly 230 (e.g., flange 242), the anchor cams 470, 470 'may be oriented such that (i) the anchor cam projection 480 does not engage/contact (or contacts to a lesser extent than in the second engagement cam position) the anchor adjustment portion 444 (see, e.g., fig. 13A) and/or (ii) the anchor cam projections 476, 476' do not engage/contact (or contacts to a lesser extent than in the second engagement cam position) the ramp portions 450, 450 'and/or the engagement ramp projections 448 (see, e.g., fig. 14A), the adjuster assembly 230 and/or the adjuster pinion 250 may disengage from the track assembly 104 (e.g., the toothed portion 154), and/or the anchor 400, 400' may engage (e.g., be disposed in the engaged position) with the toothed portion 154 of the track assembly 104.

For embodiments, such as generally shown in fig. 1A, 1B, and 12A, when the engagement cam 312 is in the second engagement cam position, the adjuster assembly 230 and/or the adjuster pinion 250 may be engaged with the track assembly 104, and/or removal of the support member 200 from the track assembly 104 may be restricted and/or prevented by the adjuster assembly 230 (e.g., depending on the position of the adjuster assembly 230), and/or the support member 200 may be adjusted relative to the track assembly 104, such as by actuating the motor 232 of the adjuster assembly 230 and/or rotating the adjuster pinion 250. In the second engagement cam position, second actuating portion 336 may be disposed adjacent to engagement cam hub 316 and spaced apart from engagement cam hub 316, first actuating portion 334 may, for example, engage, contact, and/or press against adjuster assembly 230 (e.g., flange 242) generally in the Z-direction, anchor cams 470, 470 'may be oriented such that (i) anchor cam protrusions 480 engage and/or contact anchor adjustment portions 444 (e.g., fig. 13B) and/or (ii) anchor cam protrusions 476, 476' engage and/or contact ramp portions 450, 450 'and/or disengage sloped protrusions 448 (see, e.g., fig. 14B), anchor 400, 400' may disengage toothed portions 154 of track assembly 104 (e.g., disposed in the disengaged position), and/or adjuster assembly 230 and/or adjuster pinion 250 may engage toothed portions 154 of track assembly 104. Additionally and/or alternatively, second actuating portion 336 may contact engagement camming hub 316 and/or be biased against engagement camming hub 316 when engagement cam 312 is in the second engagement cam position.

For embodiments, such as generally shown in fig. 12A and 12B, engaging and/or connecting the support assembly 102 to the track assembly 104 may include inserting (e.g., moving, sliding, rotating, etc.) the adjuster pinion 250, the adjuster assembly 230, and/or one or more anchors 400, 400 'into the track receptacle 130, and adjusting the adjuster pinion 250, the adjuster assembly 230, and/or the one or more anchors 400, 400' generally in the Y-direction into Z-direction alignment with the toothed portion 154 of the track assembly 104, which may include rotating the adjuster assembly 230 (e.g., about the adjuster axis 240) and/or the anchors 400, 400 '(e.g., about the anchor axes 402, 402'), such as by rotating the anchor cams 407, 407 'and/or by adjusting, sliding, moving, etc. the adjuster assembly 230, the anchors 400, 400', and/or the slider 270. Engaging and/or connecting the support assembly 102 to the track assembly 104 may include adjusting the adjuster pinion 250, the adjuster assembly 230, and/or one or more anchors 400, 400 'into engagement with the toothed portion 154 of the track assembly 104, such as by adjusting (e.g., moving, sliding, rotating, etc.) the adjuster pinion 250, the adjuster assembly 230, and/or the anchors 400, 400' generally upward in the Z-direction, which may include adjusting (e.g., rotating) the actuating body 330, adjusting (e.g., rotating) the engagement cam 312, and/or adjusting (e.g., sliding) the slider 270. Disconnecting and/or disconnecting the support assembly 102 and the track assembly 104 may include, for example, adjusting (e.g., moving, sliding, rotating, etc.) the adjuster pinion 250, the adjuster assembly 230, and/or the anchors 400, 400' in opposite directions, which may involve the above-described process occurring in an opposite manner.

For embodiments, such as generally shown in fig. 5A-8 and 10-11B, the regulator assembly 230, the regulator pinion 250, and/or the anchors 400, 400' may be adjusted to an engaged position, an aligned position, and/or a misaligned position by actuating the actuation shaft 292. Actuating actuation shaft 292 may include rotating actuation shaft 292 (e.g., about engagement cam axis 314), which may cause rotation of slider pinion 280, which may cause slider pinion 280 to engage toothed slider portion 276 (e.g., via slider pinion teeth 294 and slider teeth 278), which may slide, displace, move, etc., slider 270 relative to adjuster assembly 230 and/or anchors 400, 400' (e.g., generally in the X-direction), which may (i) adjust adjuster assembly 230 and/or adjuster pinion 250 from a misaligned position to an aligned position (e.g., via engagement protrusions 236) and/or (ii) adjust anchors 400, 400' from a misaligned position to an aligned position and/or to an engaged position (e.g., via engagement of anchor protrusions 442, 442 '). Continued rotation of the actuation shaft 292 (e.g., in the same direction) may (i) adjust the regulator assembly 230 and/or the regulator pinion 250 from the aligned position to the engaged position (e.g., by rotating the engagement cam 312 from the first engagement cam position to the second engagement cam position) and/or (ii) further adjust the slider 270 (e.g., generally in the X-direction), which may adjust the anchors 400, 400' from the engaged position to the disengaged position (e.g., by engaging the anchor protrusions 442, 442' with the slider recesses 304, 304 '). The actuation shaft 292 may be rotated in an opposite direction, for example, to engage (and/or subsequently disengage) the anchors 400, 400' with the track assembly 104 and/or disengage the adjuster assembly 230 and/or adjuster pinion 250 from the track assembly 104, which may involve the process described above being performed in an opposite manner.

For embodiments, such as generally shown in fig. 1A, 1B, 4, 8-9C, and 12A-14B, the regulator assembly 230 and/or the regulator pinion 250 may be (i) adjusted to an aligned position and/or a misaligned position by actuating the lever 212, and/or (ii) adjusted to an engaged position and/or an aligned position by rotating the actuation shaft 292. In such embodiments, the anchors 400, 400' can be adjusted to the engaged, aligned, and/or misaligned positions by actuating the lever 212 and/or rotating the actuation shaft 292. In some cases, rotation of the actuation shaft 292 may be limited and/or prevented when the regulator assembly 230 and/or the regulator pinion 250 are in a misaligned position (e.g., not in an aligned position or an engaged position). Additionally and/or alternatively, in some cases, actuation of the lever 212 may be limited and/or prevented when the regulator assembly 230 and/or the regulator pinion 250 are engaged with the toothed portion 154 (e.g., not in an aligned position or a misaligned position).

For an embodiment, actuation (e.g., adjustment, rotation, etc.) of the lever 212 of the support member 200 may cause the lever 212 to contact and/or press against the slider 270, which may cause the slider 270 to slide, shift, move, etc., relative to the regulator assembly 230 and/or anchors 400, 400 '(e.g., generally in the X-direction), which may cause the toothed slider portion 276 of the slider 270 to engage the slider pinion 280 (e.g., via the slider pinion teeth 294 and the slider teeth 278), which may cause the slider pinion 280 to rotate about an axis (e.g., the engagement cam axis 314), which (i) may not cause the actuation shaft 292 to rotate such that the engagement cam 312 is not adjusted and does not adjust the regulator assembly 230, and/or (ii) may cause the engagement body 310 to rotate, which may adjust the anchors 400, 400' to an engaged position, an aligned position, and/or a misaligned position. Additionally and/or alternatively, adjustment of the slider 270 by actuating the lever 212 may cause the slider 270 to (i) engage the protrusion 236 of the adjuster assembly 230, which may adjust the adjuster assembly 230 and/or the adjuster pinion 250 to an aligned position and/or a misaligned position, and/or (ii) engage the anchor protrusions 442, 442', which may adjust the anchors 400, 400' to an engaged position, an aligned position, and/or a misaligned position, and/or facilitate adjustment of the anchors 400, 400' to an engaged position, an aligned position, and/or a misaligned position. For example, and without limitation, the passages 298, 298' of the slider 270 may engage the anchor protrusions 442, 442' to adjust and/or guide the anchors 400, 400' from the misaligned position to the aligned position and/or from the aligned position to the engaged position, which may supplement the anchor biasing member 456, the anchor biasing member 456 may (e.g., simultaneously) adjust/bias the anchors 400, 400' (e.g., by providing a biasing force that biases the anchors 400, 400' toward the engaged position).

For an embodiment, the rotary actuation shaft 292 may rotationally engage the cam 312, and the engagement cam 312 may adjust the regulator assembly 230 and/or the regulator pinion 250 to the engaged position and/or the aligned position. Additionally and/or alternatively, rotating the actuation shaft 292 may rotationally engage the body 310 (e.g., by rotating the engagement cam 312), which (i) does not cause rotation of the slider pinion 280 such that movement of the slider 270 is not caused by rotation of the actuation shaft 292, and/or (ii) may adjust the engagement members 350, 350' and/or the anchor cams 470, 470' to adjust the anchors 400, 400' to the engaged, aligned, and/or misaligned positions. For example, by configuring the actuation shaft 292 to simultaneously rotationally engage the body 310 and/or engage the cam 312, one or more anchors 400, 400' may be disengaged from the track assembly 104 and/or the adjuster assembly 230 may be engaged with the track assembly 104 (or vice versa) by a single action (e.g., rotating the actuation shaft 292), which may facilitate adjustment of the support assembly 102 relative to the track assembly 104.

For example, but not limiting of, upon insertion of the support assembly 102 into the track assembly 104, the anchors 400, 400', the adjuster assembly 230, and/or the adjuster pinion 250 may be disposed in or near a misaligned position to facilitate insertion/connection. The lever 212 may then be actuated to adjust the slider 270, which may (i) adjust the adjuster assembly 230 and/or the adjuster pinion 250 from the misaligned position to the aligned position (e.g., via the engagement tab 236) and/or (ii) adjust the anchors 400, 400 'from the misaligned position and/or the aligned position to the engaged position (e.g., via the anchor biasing member 456, engage the anchor tabs 442, 442' and/or rotate the slider pinion 280 to rotate the engagement body 310 without rotating the actuation shaft 292). Subsequently, the actuation shaft 292 may be rotated, which may (i) adjust the adjuster assembly 230 and/or the adjuster pinion 250 from the aligned position to the engaged position (e.g., by rotating the engagement cam 312) and/or (ii) adjust the anchors 400, 400' from the engaged position to the aligned position and/or the misaligned position (e.g., by rotating the engagement cam 312 to rotationally engage the body 310 without rotating the slider pinion 280), which may unlock the support assembly 102 from the track assembly 104 to facilitate movement of the support assembly 104 along the track assembly 104 via the adjuster assembly 230. The actuation shaft 292 may be rotated in the opposite direction, or the lever 212 may be actuated in the opposite direction, e.g., to engage the anchors 400, 400' with the track assembly 104 and/or disengage the adjuster assembly 230 and/or the adjuster pinion 250 from the track assembly 104, which may involve one or more portions of the above-described process occurring in the opposite manner.

For embodiments, such as generally shown in fig. 1B, adjusting the adjuster pinion 250 and/or the adjuster assembly 230 to be Z-directional aligned with the toothed portion 154 of the track assembly 104 and/or not Z-directional aligned with the toothed portion 154 of the track assembly 104 may include rotating the adjuster pinion 250 and/or the adjuster assembly 230 about the adjuster axis 240, such as by adjusting, sliding, moving, etc., the adjuster assembly 230 and/or the slider 270. The slider 270 and/or the regulator assembly 230 may be adjusted, moved, slid, etc. (e.g., generally in the X-direction), which may cause the protrusion 236 to engage the guide surface 282 and/or slide along the guide surface 282, which may cause the regulator assembly 230 and/or the regulator pinion 250 to adjust (e.g., rotate) toward and/or away from the toothed portion 154 of the track assembly 104. Adjusting the slider 270 and/or the adjuster assembly 230 to adjust the adjuster pinion 250 into a Z-direction alignment with the toothed portion 154 of the track assembly 104 may include actuating the lever 212 and/or rotating the actuating shaft 292, which may cause the slider 270 to slide, shift, move, etc. relative to the adjuster assembly 230 (e.g., generally in the X-direction), which may cause the tab 236 to slide along the guide surface 282 toward the middle section 286 (e.g., from the first end 284), which may cause the adjuster assembly 230 to rotate about the adjuster axis 240, which may adjust the adjuster pinion 250 generally in the Y-direction toward the toothed portion 154 of the track assembly 104 (e.g., away from the slider 270). The slider 270 and/or the adjuster assembly 230 may be adjusted/moved, for example, in an opposite direction to adjust the adjuster assembly 230 and/or the adjuster pinion 250 out of Z-direction alignment with the toothed portion 154 of the track assembly 104, as well as to the process described above that proceeds in an opposite manner.

For embodiments, such as generally shown in fig. 12A and 12B, adjusting the adjuster pinion 250 and/or the adjuster assembly 230 into and/or out of engagement with the toothed portion 154 of the track assembly 104 may include adjusting the adjuster assembly 230 generally in the Z-direction, such as by rotating the actuating body 330 and/or engaging the cam 312. When the engagement cam 312 is adjusted to engage the regulator assembly 230 and/or the regulator pinion 250 with the toothed portion 154 of the track assembly 104 (e.g., adjust the regulator assembly 230 from the position of fig. 12B toward the position of fig. 1A, 1B, 12A), the engagement cam 312 may be rotated about the engagement cam axis 314, such as by rotating the actuation shaft 292, which may cause the second actuation portion 336 of the engagement cam protrusion 318 to adjust, move, slide, move away from the engagement cam protrusion 318 (e.g., to a position where the second actuation portion 336 is disposed slightly spaced from and/or in contact with the engagement boss 316), which may cause the actuation body 330 to rotate about the actuation body axis 332 (e.g., clockwise in the view of fig. 12B), which may cause the first actuation portion 334 to move generally upward in the Z-direction, such that the first actuation portion 334 adjusts, presses, pushes, etc. the flange 242 of the regulator assembly 230 generally upward in the Z-direction, which may cause the regulator assembly 230 and/or the regulator pinion 250 to move generally upward in the Z-direction to engage the toothed portion 154. The actuation shaft 292, engagement cam 312, and/or actuation body 330 may be adjusted, moved, rotated, etc., e.g., in opposite directions to disengage the regulator assembly 230 and/or regulator pinion 250 from the toothed portion 154 of the track assembly 104 (e.g., adjust the regulator assembly 230 from the position of fig. 12A to the position of fig. 12B), which may involve the above-described process occurring in an opposite manner.

For embodiments, such as generally shown in fig. 8, engaging and/or disengaging the anchors 400, 400 'with the toothed portion 154 of the track assembly 104 may include adjusting, sliding, moving, etc. the anchors 400, 400' and/or the slider 270. The slider 270 may be adjusted, moved, slid, etc. (e.g., generally in the X-direction), such as by rotating the actuation shaft 292 and/or actuation lever 212, which may cause the anchor protrusions 442, 442' to engage the slider channels 298, 298' and/or slide along one or more slider walls 300, 302, 300', 302', which may cause the anchors 400, 400' to adjust (e.g., rotate, slide, raise, lower, etc.) toward the aligned position, the misaligned position, the engaged position, and/or the disengaged position, which may connect (e.g., temporarily secure) and/or disconnect the support member 200 and the track assembly 104. In an example, adjustment of the anchor protrusions 442, 442' within the passages 298, 298' may supplement the anchor biasing member 456 and/or may be supplemented by the anchor biasing member 456, the anchor biasing member 456 may adjust/bias the anchors 400, 400' toward the engaged position.

For embodiments, such as generally shown in fig. 8, adjusting, moving, and/or sliding the slider 270 and/or anchors 400, 400 'such that the anchors 400, 400' engage the toothed portion 154 of the track assembly 104 (e.g., toward the position of the anchors 400, 400 'shown in fig. 11A) may include adjusting/moving the anchor protrusions 442, 442' within the first sections 298A, 298A 'of the slider channels 298, 298 (e.g., toward the second sections 298B, 298B').

In an embodiment, further adjustment of the slider 270 (e.g., generally in the X-direction) and/or the anchors 400, 400 'may cause the anchor protrusions 442, 442' to adjust/move within the second sections 298B, 298B 'of the slider channels 298, 298' (e.g., toward the third sections 298C, 298C '), which may cause the anchors 400, 400' to adjust generally downward in the Z-direction away from the toothed portion 154 of the track assembly 104 at least to some extent, which may facilitate rotation of the hook portion 408 under the toothed portion 154. Additionally and/or alternatively, adjusting/moving the anchor protrusions 442, 442 'within the second sections 298B, 298B' of the slide channels 298, 298 '(e.g., toward the third sections 298C, 298C') may cause the anchors 400, 400 'to rotate about the anchor axes 402, 402', which may adjust the toothed anchor portions 412, 412 'generally in the Y-direction toward the toothed portion 154 of the track assembly 104 (e.g., away from the slide 270), which may cause the toothed anchor portions 412, 412' to be disposed in Z-direction alignment with the toothed portion 154.
