Systems and methods for fluid delivery in seat systems

## Abstract

The present invention relates to systems and methods of delivering fluid from one or more armrests of seat systems. In a feature, the system includes a seat support assembly with armrests with one or more fluid nozzles mounted on one or more of the armrests, a fluid delivery system coupled to the one or more fluid nozzle(s), wherein the fluid nozzles are mounted on an end of the armrest that slopes upward to direct fluid toward the viewer. In another feature, the system includes a controller (e.g., a network server) configured to communicate on and off commands that correspond to events on a timeline of a movie to actuate the fluid delivery system to deliver fluids to the nozzles.

## Background
BACKGROUND
The present invention relates to systems and methods of fluid delivery for effects for a viewer in a seat system.
Disney's Star Tours and Universal Studio's The Simpsons Ride, commercial movie theaters, gaming environments, and training centers (e.g., military, law enforcement, and flight schools) use effects to produce the sensation that one is immersed in the reality displayed on a movie screen.
A motion effect is implemented by synchronizing the seat motion of the viewer to correspond to the displayed scenes. The motion seat systems can be adapted to receive motion signals that move seats to correspond (e.g., synchronize) to other signals (e.g., video and/or audio signals) that are perceived by person(s). For example, the seat system may synchronize seat motions with the displayed motions in a theater to simulate the forces one would experience seated in a vehicle in a chase scene where the vehicle races around a city street.
Another effect is to deliver fluids such as a water mist, a blast of air, wind, and one or more scents to the viewer with the displayed scenes. For example, a system may deliver an orange scent to the viewer while movie displays a character traveling through an orange orchard, deliver a water mist to the viewer when the character travels through a rainy jungle or wind in a storm scene. To the inventors' awareness, the wind effect is implemented by fans hanging in a theater, but this may distract from the viewer's experience and may be noisy. The water mist and scents have been implemented by installing nozzles in a front rail in front of a row of seats or installing the nozzles into the back of the seats in front of the viewers, but either approach is expensive to implement and not practical because the motion of the seats affects the directionality of the fluid delivery. In short, the motion seats may move the viewer out of the path of fluid delivery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description includes the best mode of carrying out the invention. The detailed description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is determined by reference to the claims. Each part is assigned its own part number throughout the specification and drawings.
FIG. 1 illustrates a seat support assembly that is suitable for the system. In this embodiment, the system 10 includes a seat support assembly 42 that includes a top frame 36 and a bottom frame 40. Front actuators 15 and 19 and a back actuator 23 provide structural support between the top and bottom frames 36 and 40. The actuators also provide motion to the seat support assembly 42. U.S. Pat. No. 8,585,142 B2 to Jamele et al., Motion Seat Systems and Methods of Implementing Motion in Seats, which is incorporated by reference herein, describes motion seat systems that are suitable with the systems.
FIG. 1 also illustrates that in an embodiment a seat frame 32 is secured (e.g., bolted and welded) to the top frame 36. The seat frame 32 has four spaces 14, 16, 18, and 20 for the seats. Armrests 12, 17, 22, 28, and 34 are secured (e.g., bolted and welded) to the seat frame 32. A seat 21 in space 16 illustrates how the other seats (not shown) fit and are secured in spaces 14, 16, 18, and 20 on the seat support assembly 42.
In an embodiment, the seat support assembly 42 contains space for a fluid delivery system 24 (shown in FIG. 5) and a programmable controller 13. FIGS. 5-6 and the accompanying specification will describe both in detail.
FIG. 2 illustrates a back side view of the system shown in FIG. 1. As shown, the armrest 22 includes a set of nozzles 44, 46, 50, and 52 that reside in holes in a sloped plate 48 at the end of armrest 22. The nozzles 50 and 52 will be used to distribute fluids such as air, water, and/or scents to a viewer in seat 21, while the nozzles 44 and 46 will be used to distribute fluids such as air, water, and/or scents to a viewer in a seat (not shown) that will occupy space 18. A suitable water nozzle is the Hago water nozzle MW5 that can be obtained from the Hago Manufacturing in Mountainside, N.J. A suitable air nozzle is the SMC muffler ASP-2 that can be obtained from SMC in Noblesville, Ind. This fluid distribution will be described in detail in connection with FIGS. 4A-5.
Similarly, the armrest 17 includes a set of nozzles 54, 56, 60, and 62 that reside in holes in a sloped plate 58 at the end of the armrest 17. The nozzles 54 and 56 will be used to distribute fluids such as air, water, and/or scents to a viewer in the seat 21, while the nozzles 60 and 62 will be used to distribute fluids such as air, water, and/or scents to a viewer in a seat (not shown) that will occupy space 14.
FIG. 3 is an external view of the armrest 17 apart from the seat support assembly 42 (FIGS. 1-2). A cover 64 adjacent to or integral with the nozzle plate 58 is a protective enclosure for the nozzles 54, 56, 60, and 62 and their respective fluid lines. A suitable fluid line is plastic tubing such as Festo PUN-6x1 plastic tubing from Festo in Esslingen am Neckar, Germany.
FIG. 4A is an internal view of the armrest shown in FIG. 3. The cover 64 of armrest 17 is partly removed to reveal that the nozzles 54 and 56 residing in nozzle plate 58 are secured to the mounting plate 68 and coupled to nozzle fittings 66 and 70, which in turn are coupled to a first fluid line 72 and a second fluid line 74. A suitable water nozzle fitting is the SMC KQ2K06-01AS and a suitable air nozzle fitting is the SMC KQ2F07-35, both from SMC in Noblesville, Ind.
FIG. 4B is an internal view of the components in the armrest. The front cover 64 is fully removed from armrest 17 to reveal that the nozzles 54, 56, 60 and 62 are secured to the mounting plate 68 and are coupled to the nozzle fittings 66, 70, 76, and 78, which in turn are coupled to the fluid lines 72, 74, 80, and 82.
FIG. 5 illustrates an embodiment of a fluid delivery system that can be used to distribute water, air, and scents to the nozzles shown in FIGS. 2-4B.
As illustrated, the fluid delivery system 24 includes a valve array 88. A suitable valve array can be assembled from Festo valve manifold VABM-L1-14S-G14-5 and Festo valves VUVG-L14-T32C-AT-G18-1P3, which can be obtained from Festo, Esslingen am Neckar, Germany. The valve array includes an air inlet 85, a high flow air outlet 98, a low flow air outlet 96, a first scent outlet 94, a second scent outlet 92, and/or an air outlet 99.
An air supply source (not shown), e.g., an air compressor at 100 psi, supplies air to the air inlet 85. In an embodiment, a high flow air line 124 is connected from the air outlet 98 through a high flow air regulator 114 to the fluid line 72. A low flow air line 122 is connected from the air outlet 96 through a low flow air regulator 112 to the fluid line 72. A first scent line 120 is connected from the air outlet 94 through a first scent flow regulator 110 and a first scent tank 89 to the fluid line 72. A second scent line 118 is connected from the air outlet 92 through a second scent flow regulator 108 and a second scent tank 90 to the fluid line 72. As a result, the first fluid line 72 is able to deliver high air flow (e.g., air blast), a low air flow (e.g., wind), and scent(s)(e.g., freshly cut grass) through a single air nozzle 56 (FIG. 4B). A suitable flow regulator is the SMC AS2051FG-08 Inline Flow Control from SMC in Noblesville, Ind. A suitable scent tank is the Clear Inline DI Filter Cartridge 214 that can be obtained from Filter Direct in Santa Ana, Calif. A suitable scent source is the Scent Sleeve from Escential Resources FX from Torrance, Calif.
In additional embodiments, the air flow regulators 108, 110, 112, 114, and 116 can be replaced by pressure regulators. A suitable pressure regulator is the SMC AW30-N03-Z Filter Regulator from SMC in Noblesville, Ind. In another embodiment, the air flow regulators 108, 110, 112, 114 and/or 116 and/or the pressure regulators can be omitted. In other embodiments, the air flow regulators 108, 110, 112, 114, and 116, or the pressure regulators, can be positioned anywhere along their respective air lines 118, 120, 122, 124, and 126, or can be positioned upstream from the air inlet 85.
A water pump (not shown), e.g., 30-70 psi, supplies water to the water inlet 102 of the water valve 101, which couples the water line 128 from the water outlet 100, through a shut-off valve 103, to the fluid line 74. An atomizing air line 126 is coupled to the air outlet 99 and to an air flow regulator 116. The atomizing air line 126 is coupled to the fluid line 74. As a result, the fluid line 74 is able to deliver a fine spray of atomized water (e.g., mist) and/or water through a single water nozzle 56 (FIG. 4B). When the atomized water is delivered both the air outlet 99 and the water valve 101 are opened. A suitable water valve is the SMC water valve VDW22AA from SMC in Noblesville, Ind.
Many of the parts of the systems can be purchased and implemented with high strength steel, but the person of ordinary skill would readily understand the materials and parts to use after review of the specification. Further, the choice of materials and conventional parts is not essential to the invention.
FIG. 6 is a flowchart of the process and hardware transmitting commands from the controller to valves to control the fluid delivery system. In an embodiment, using known conventional techniques, the system can include a controller 130 that transmits a digital command to a programmable controller 132, which in turn transmits an analog voltage to an electrical terminal 134, which in turn sends the analog voltage to the valve array 88 (FIG. 5) and/or the water valve 101, collectively called valves 136, to actuate the valve(s). As indicated in FIG. 6, one or more of the hardware components 130, 132, and 134 can be omitted from the control process. In an alternative embodiment, an operator will manually actuate the valves 136 to achieve the desired effects.
FIGS. 1-6 illustrate the fluid delivery systems and methods of fluid delivery in a four-seat support assembly. However, the inventors recognize the fluid delivery system may be implemented for one or more seats, and each seat may include one or more armrests. Furthermore, the system may be implemented by an operator rather than a controller (e.g., a network computer), which is also referred to as a central controller. It is also recognized that the system is not limited to seating designed for commercial theaters, theme parks, exhibits, home theaters, and gaming. For example, it may be used in any environment where fluid effect will enhance or change the experience of the viewer in the seat.
Thus, the systems and methods described also eliminate the need for mounted fans to produce in-theater effects such wind. In addition, the system eliminates the need for rails mounted in front-row seats and water jets on the back of each additional row. Instead, the effects (e.g., air blasts, wind, water, mist and scents) are implemented at the armrest of the seat of the viewers. If the seat also moves, the effects move along with the viewer.
The design of the system allows unlimited configurations as to the number of seats, and also may provide each rider with the same experience at a relatively low cost.
