[0001] Related applications

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 568,609, filed on March 22, 2024, entitled “Seating Apparatus with Accessory Rail System,” which is hereby incorporated by reference in its entirety. Background Art

[0003] Seating comfort is often expressed in one of several ways. First, a seat with minimal yield can be comfortable, such as a hard-back chair designed to conform to the body shape of a typical user. Second, a seat may lack a specifically designed contour but offer excellent yield, as seen in a foam-padded seat. Suspended fabrics, or suspended fabrics, have emerged as a common alternative to hard surfaces and foam padding in seating.

[0004] Specially designed suspended fabric surfaces can provide the comfort of foam padding at a weight similar to that of a hard plastic seat and at a relatively low cost. Notably, suspended fabric seats enhance comfort through preset tensions in the fabric that can be adjusted to meet comfort targets, providing regional tension on the seat surface. When placed within a curved frame, this design adds a stylish feature and an ergonomic profile that facilitates reclining movement. An example of such a seating arrangement utilizing suspended fabric is described in detail in commonly owned U.S. Patent No. 11,452,380, entitled "Seat Comprising Suspension Fabric with Compression Limiters."

[0005] Despite the advances in comfort achieved to date, there remains a need for an improved seating arrangement that allows for easy user and / or customer customization or modification, such as easy installation of accessories for specific use cases. Summary of the Invention

[0025] The disclosed rail system allows the user to easily attach and detach accessories as needed, providing flexibility and convenience in a variety of environments. The rail system described herein provides a practical and versatile solution for attaching accessories (such as headrests, cup holders, charging ports) to a seating arrangement. The rail system and the secure attachment mechanism provide convenience, stability, and compatibility in a variety of applications. Although generally shown and described with respect to a seating arrangement, the rail system can be used with a variety of objects, and thus the rail tracks can be mounted on a variety of objects, including but not limited to vehicles, furniture, strollers, bicycles, and fitness equipment.

[0026] In some examples, the seating arrangement is an office chair, a stadium seat, or a vehicle seat.

[0027] Figure 1a and Figure 1b An example seating arrangement 100 having a rail system 124 according to one aspect of the present disclosure is shown. As will be appreciated, the rail system 124 implements a standardized attachment design that enables accessory attachment and, in some cases, can be configured to conceal wiring harnesses and communication conductors from view and protect such conductors from tampering and abuse. For example, Figure 1a A rear perspective view of the first seating arrangement 100 with a wheeled base 132 is shown. Figure 1b A rear perspective view of the seating arrangement 100 is shown with a fixed base 140. Figure 6a 、 Figure 6b 、 Figure 7a and Figure 7b Additional examples are shown and described.The seating arrangement 100 generally comprises a seat section 100a and a support section 100b.

[0028] The illustrated seating arrangement 100 generally includes a seat assembly 104 and a back support assembly 102. In some examples, the seating arrangement 100 further includes a headrest assembly 114, a cup holder assembly 122, a charging port assembly 500, and one or more armrests 128. The headrest assembly 114, the cup holder assembly 122, and / or the charging port assembly 500 are removably coupled to a track system 124 of the seating arrangement 100 via one or more attachment mechanisms 120. The seat assembly 104 and the back support assembly 102 can be adjustable relative to each other (e.g., the angle at which they are arranged) and relative to the ground (e.g., the height between the seat assembly 104 and the ground).

[0029] Depending on the application, the seat assembly 104 and the back support assembly 102 can be supported relative to the ground via, for example, a wheeled base 132 or a fixed base 140. For example, the seat assembly 100 can be an office chair using a wheeled base 132, which is composed of a frame 134, a plurality of wheels 138, and a chair hydraulic cylinder 136. Additionally, the seat assembly 100 can be configured to adjust between various ergonomic positions. In another example, the seat assembly 100 can include a fixed base 140, which can include one or more supports 142 (e.g., legs, frame structures, etc.) and feet 144 (e.g., slide bars, sliders, brackets, foot plates, etc.). In some examples, the seat assembly 100 can be secured to the ground at the feet 144 (e.g., via one or more tracks or fasteners, such as bolts). By way of illustration, the seat assembly 100 can be positioned in a manner such as Figure 7b The transportation facilities shown (e.g., airplanes, trains, buses, cars, etc.) or Figure 1b 、 Figure 6a and Figure 6b The disclosed rail system 124 is shown secured to the ground in the context of public venue installations (e.g., stadium seating, theater seating, etc.). Thus, the disclosed rail system 124 may be applied to a variety of industries requiring better suspended seating integration, such as transportation applications, residential uses, public spaces, large venues (e.g., stadiums and arenas), houses of worship, educational institutions, entertainment venues, offices, and the like.

[0030] The illustrated back support assembly 102 includes a back frame 110 that generally defines a back opening 130, which can be oval, quadrilateral (e.g., rectangular, square, etc.), or other desired shape. A suspended seat fabric can be stretched or otherwise extended across the back opening 130 to define a back support surface 112. The back support surface 112 can be secured to the back frame 110 along a perimeter (e.g., the entire perimeter) of the back support surface 112.

[0031] In this example, the back frame 110 is configured to define or otherwise function as a rail system 124 that is configured to be compatible with a wide variety of objects and accessories, allowing an end user to customize its configuration by attaching various accessories as desired. That is, the rail system 124 can be integrally formed with the back frame 110.

[0032] Each of the one or more attachment mechanisms 120 can be configured as a first bracket 120a that is secured to an accessory (e.g., integrated with, part of, or otherwise attached to the accessory) and a second bracket 120b that is complementary to the first bracket 120a. The first bracket 120a and the second bracket 120b are configured to clamp and retain the rail system 124 (e.g., via fasteners 120c). In some examples, the first bracket 120a and the second bracket 120b can be hingedly coupled to each other in a clamshell arrangement for ease of installation.

[0033] The illustrated seat assembly 104 includes a seat frame 106 that generally defines a seat opening, which may be oval, quadrilateral, or another desired shape. A suspended seat fabric may be stretched or otherwise extended across the seat opening to define a seat support surface 108. Like the back support surface 112, the seat support surface 108 may be secured to the seat frame 106 along its perimeter (e.g., its entire perimeter).

[0034] The illustrated headrest assembly 114 includes a headrest frame 116 that generally defines a headrest opening, which may be oval, quadrilateral, or another desired shape. A suspended seat fabric may be stretched or otherwise extended across the headrest opening to define a head support surface 118. The head support surface 118 may be secured to the headrest frame 116 along a perimeter (e.g., the entire perimeter) of the head support surface 118.

[0035] In some examples, the seat frame 106 and / or the headrest frame 116 can also be configured to define or otherwise function as a rail system 124 to enable an end user to attach various accessories to the seat assembly 104 (e.g., an under-seat fire extinguisher, a life vest, etc.) and / or the headrest assembly 114 (e.g., for attaching headphones). The back frame 110, the seat frame 106, and / or the headrest frame 116 can be manufactured using relatively durable materials such as plastic, metal, or composite materials.

[0036] Figure 2a and Figure 2b A cross-sectional view of the back frame 110 of the back support assembly 102 taken along section line AA (FIG. 1A) is shown illustrating the rail system 124 and its rail tracks 202 according to one aspect of the present disclosure, and Figure 2c A cross-sectional view of the back frame 110 of the back support assembly 102 is shown, taken along section line BB (FIG. 1A).

[0037] As shown, the rail system 124 can be or include a rail track 202 positioned along the perimeter of the backrest opening 130. In the example shown, the rail track 202 is formed around the entire perimeter of the backrest opening 130. The rail track 202 provides a convenient way to customize and enhance the functionality of the seating arrangement 100 by allowing a user to attach accessories to the backrest assembly 102 or elsewhere.

[0038] Using the guide rails 202 and one or more attachment mechanisms 120, various accessories can be easily attached to the backrest assembly 102. These accessories include a headrest assembly 114, a cup holder assembly 122, a charging port assembly 500, a head restraint, a tray, a cell phone charger (both wired and wireless), a book support (e.g., for religious texts), a kick plate, a slide for the telescopic structure, an entertainment screen (similar to the screen in a car), waste and garbage containers / bags, food containers, toys, books, comfort protection devices, bar codes and venue digital information. Additionally, the seating arrangement can implement chair-to-chair connections (e.g., for rows of seats), lumbar support assemblies, game controllers, computers, local interconnect network (LIN) communication modules, piezoelectric modules for massage and comfort enhancement, heating and cooling modules, and duct systems for forced air directional features. These accessories enhance the diversity and functionality of the seating arrangement, thereby catering to a wide range of user preferences and needs.

[0039] like Figures 2a to 2c As best shown, the back frame 110 generally includes a body 206 having a guide rail 202 positioned on a first side (outside of the back frame 110) and a fabric slot 208 positioned on a second side (inside of the back frame 110). The fabric slot 208 is configured to secure a perimeter of a suspended seat fabric to define a back support surface 112 (an example of which is shown in FIG. Figure 3b ). The cross-sectional profile of the guide rail 202 of the back frame 110 can be substantially the same around the perimeter of the backrest opening 130, for example, to allow attachment of accessories at any location around the perimeter of the backrest opening 130. In this example, the attachment mechanism 120 generally employs a C-clamp design theme. The illustrated guide rail 202 includes a bulbous portion 202a having a generally circular or oval cross-section, which is coupled to and spaced apart from the body 206 via a neck portion 202b. The bulbous portion 202a allows the accessory to be repositioned at any location around the perimeter of the backrest opening 130.

[0040] In some examples, the guide rail 202 can further include a series of attachment point features along its perimeter to mitigate slippage or sliding along the guide rail 202. The attachment point features can be positioned or formed in or on the ball portion 202a and / or the neck portion 202b. The attachment point features can be, for example, slots, protrusions, or other features to increase friction along the guide rail 202, thereby mitigating slippage of the attachment mechanism 120 relative to the guide rail 202. In examples where the attachment point features are omitted, the outer surface of the guide rail 202 is substantially smooth along its perimeter.

[0041] The described rail system 124 offers numerous advantages, including versatility, convenience, stability, and compatibility. The rail system 124 accommodates a variety of accessories, allowing users to customize their setup for different purposes. The attachment mechanism enables quick and easy installation and removal of accessories, enhancing user convenience. The secure fastening mechanism ensures that attached accessories remain securely in place during use, preventing accidents or dislodging. The rail system 124 is compatible with a wide range of objects and accessories, providing flexibility in different applications.

[0042] In some scenarios, the guide rail 202 (such as the ball portion 202a) and / or the attachment mechanism 120 may include electrical conductors 204 to enable electrification (e.g., for charging) and data communication. Figure 2a and Figure 2b , the bulbous portion 202a may contain embedded electrical conductors 204 that are introduced or formed during the molding process of the back frame 110. This integration allows the suspension frame resin to encapsulate the conductors 204, thereby enhancing durability and resistance to weather and abuse. In this arrangement, as will be combined Figure 5a and 5b As discussed in the example of FIG, when the attachment mechanism 120 is fully clamped, it can establish contact with the electrical conductor 204 in the ball portion 202a, thereby effectively clamping the ball portion 202a. To prevent accidental grounding or shorting, the positive and negative electrical conductors 204 are electrically isolated. Additionally, multiple electrical conductors 204 can be embedded to support functions such as a local interconnect network (LIN), a universal serial bus (USB), or multi-line digital communication (e.g., an Ethernet 8-wire system).

[0043] Figure 3a A rear perspective view of a headrest assembly 114 according to one aspect of the present disclosure is shown, and Figure 3b A cross-sectional view of the interface between the headrest assembly 114 and the back frame 110 of the back support assembly 102 is shown in accordance with an aspect of the present disclosure.

[0044] The attachment mechanism 120 is configured to securely fasten the accessory to the guide rail 202, thereby preventing accidental detachment or slippage during use. In this example, the attachment mechanism 120 includes a first bracket 120a and a second bracket 120b, which are configured to clamp and hold the ball portion 202a of the guide rail 202 (e.g., via a fastener 120c). To this end, the first bracket 120a includes a first recess 302a and the second bracket 120b includes a second recess 302b, which cooperate when assembled to define a channel 302 that generally corresponds to the outer shape of the ball portion 202a in the clamping arrangement. Although illustrated using a clamping arrangement with a threaded fastener 120c, the attachment mechanism 120 can include locking features, such as a spring-loaded pin, a latch, etc., to ensure a stable connection between the attachment mechanism 120 of the accessory and the guide rail 202. For ease of assembly, the first bracket 120a may be attached to the second bracket 120b via, for example, a living hinge to form a clamshell arrangement.

[0045] Figure 4a A front perspective view of a cup holder assembly 122 according to one aspect of the present disclosure is shown. Figure 4b A cross-sectional view of the interface between the cup holder assembly 122 and the back frame 110 of the back support assembly 102 is shown in accordance with an aspect of the present disclosure.

[0046] The cup holder assembly 122 is configured to securely hold cups, bottles, and similar containers, thereby enhancing the usability of the object equipped with the rail system 124, thereby providing ease of use and adaptability in different applications. The cup holder assembly 122 is configured to be removably mounted on the rail track 202. The cup holder assembly 122 includes a cup holder component 402 having a cavity or holder for receiving a container 126 (e.g., a cup, bottle, or other container). The cup holder assembly 122 further includes an attachment mechanism 120 that engages with the rail track 202, such as a point along the rail track 202 and / or an attachment point or slot formed in or on the rail track 202.

[0047] Figure 5a A front perspective view of a charging port assembly 500 according to one aspect of the present disclosure is shown, and Figure 5b A schematic cross-sectional view of the interface between the charging port assembly 500 and the back frame 110 of the back support assembly 102 is presented.

[0048] The charging port assembly 500 is configured to provide power through one or more charging ports 504, thereby enabling a user to charge or power an electrical device. These charging ports 504 can be configured to supply AC or DC power, thereby drawing power from the guide rail 202 or an alternative power source (e.g., a wall plug connected to mains electricity). For example, the charging port 504 can include an AC socket 504a (e.g., a 120V AC or 240V AC socket) and / or a DC socket 504b (e.g., a 5V DC universal serial bus (USB) port, a barrel plug, etc.). In some examples, the charging port assembly 500 can additionally or alternatively provide data communication via one or more charging ports 504. For example, the DC socket 504b (e.g., in the case of USB) can also be configured to perform data communication between the user device and the seat device 100.

[0049] The source power can then be converted or inverted by the charging circuitry 506 to deliver the desired current, voltage, and power type (AC or DC). The charging circuitry 506 can utilize step-down and step-up converters, as well as buck-boost converters that can both step up and down the voltage. For AC and DC conversion, an inverter converts DC to AC, a rectifier converts AC to DC, and an AC-AC converter modifies the AC voltage or frequency.

[0050] The charging port assembly 500 also includes an attachment mechanism 120 that engages the guideway rail 202 at a designated point or via an attachment point or slot formed on the guideway rail 202. The assembly is configured to be removably mounted on the guideway rail 202. Where applicable, it features a housing 502 with an internal cavity to house the charging circuit 506 and retain the charging port 504. The charging port assembly 500 receives power from positive and negative electrical conductors 204 embedded in the guideway rail 202. In some examples, at least a portion of the electrical conductors 204 may be flush with the surface of the guideway rail 202 or include an electrical bridge between the electrical conductors 204 and contacts (e.g., metal contact pads) on the surface of the guideway rail 202, thereby allowing the charging port assembly 500 to electrically connect to the electrical conductors 204 via contacts (e.g., spring pins or other electrical connectors) positioned on the inner surface of the attachment mechanism 120 (e.g., on the first bracket 120a along or in the first recess 302a).
