As exemplified in FIGS. 1-4, the outlet 166 may face at least partially rearwardly and at least partially upwardly. As exemplified in FIGS. 1-4, the outlet 166 may face in an upward and rearward direction 138.

[0060] A control system 220 may control operation of one or more selectively activatable components, such as the fluid moving member 172 or a user interface 222. For example, a user interface 222 may include one or more LED status lights. In some examples, a user interface 222 may include one or more user control toggles for providing user input. The control system 220 may include one or more processor and one or more data storage device. The control system 220 may control when the activatable component is active (e.g., turning the activatable component on or off), and may control a setting of the component if the component includes more than one setting (e.g., switching the component between a first setting and a second setting, such as a first fan speed and a second fan speed).

[0061] In some examples, the armrest 140 includes a sensor bracket 224. In some examples, the armrest 140 includes a photoelectric sensor switch 226. In some examples, the armrest 140 includes a solenoid valve 228. In some examples, the armrest 140 includes a solenoid plug and cable 230. In some examples, the armrest 140 includes one or more push-to-connect tube fitting (e.g., with universal thread) 232. In some examples, the armrest 140 includes a control board (e.g., a PCBA) 234.

[0062] In accordance with an aspect, a fluid delivery system includes an air flow path and is arranged to direct an outlet air flow as a substantially laminar flow of air towards a user seated in the user seat. The air moving member may be an axial fan, and a louver assembly may be positioned in the air outlet 166 wherein the louver assembly is arranged to direct the expelled air as a substantially laminar flow of air towards a user seated in the user seat.

[0063] Referring again to FIG. 8, in some examples, the fluid flow path 162 is an airflow path, the fluid inlet 164 is an air inlet, the fluid outlet 166 is an air outlet, and the fluid moving member 168 is an air moving member. In some examples, an air moving member is a fan unit (e.g., a motor and fan assembly) contained within the housing and positioned in the airflow pathway, wherein the fan unit is operable to draw air in through the air inlet 164 and expel air through the air outlet 166. The exemplary member 168 includes an axial fan 172.

[0064] A louver assembly 174 is positioned at the air outlet 166. The exemplary louver assembly 174 of FIG. 8 is part of an outlet head 178. The louver assembly 174 is arranged to direct the expelled air as a substantially laminar flow of air towards a user seated in the user seat 110. Referring now to FIGS. 9-12, and particularly FIG. 10, the exemplary louver assembly 174 includes a plurality of foils 176. The foils 176 may be fixed in position within a head 178. The exemplary louver assembly 174 of FIG. 10 includes at least one plurality of generally parallel foils 176 (e.g., a set of generally horizontal foils 176a and/or a set of generally vertical foils 176b) to reduce a vortex air pattern that comes out of the axial fan 172. The foils are shaped to change the angle of an airflow to direct and concentrate the air towards the user. A foil 176 may be generally planar or may be curved. The exemplary vertical foils 176b of FIG. 10 are generally curved, with a concave surface facing inwards towards a centre of the assembly 174.

[0065] The exemplary horizontal foils 176a of FIG. 10 change angle and/or curvature from a point that is generally aligned with the centre of the axial fan 172 (e.g., the center of the louver assembly 174) out to the lateral edge, since air velocity and volume from the axial fan 172 are highest at the tips of the blades of the fan and less at the center of the fan. As exemplified in FIG. 10, the horizontal foils 176a may include a foil at a first lateral side 180 and another foil at a second lateral side 182 that slopes downstream and upwardly more than the foil at the first lateral side 180. The horizontal foils 176a may sequentially change stepwise from the angle at the first lateral side 180 to the angle at the second lateral side 182. The change in angel may be generally constant from one foil to the next. In some examples, the axial fan 172 mounted behind the louver assembly 174 rotates clockwise 184a in use. In some examples, the axial fan 172 mounted behind the louver assembly 174 rotates counterclockwise 184b in use. The change in angle and/or curvature of a set of generally parallel foils may follow the direction of rotation of the axial fan 172 or run counter to the direction of rotation of the axial fan 172.

[0066] In some examples, the exterior of the louver assembly 176 is shaped to reduce turbulence. In some examples, the exterior of the louver assembly 176 is shaped to produce an air inducement effect to pull surrounding air into the air stream. The exemplary louver assembly 176 of FIGS. 9-12 projects the outlet 166 downstream, e.g., beyond any other components to reduce turbulence. The exemplary louver assembly 176 of FIGS. 9-12 includes smooth surfaces curving out towards the outlet 166.

[0067] In some examples, the head 178 includes a closed region 186 overlying the centre of the axial fan 172 (e.g., in the centre of the head 178) to reduce turbulence. The closed region 186 may be the base of a cone shaped closed space within the coils 176.

[0068] It will be appreciated that the fluid flow path may be adapted for use with different seat configurations. For example, a fluid flow path may direct air flow to each of first and second adjacent seats, or only to one adjacent seat. A fluid flow path adapted to direct air flow to only one adjacent seat may be mounted at the first side 122 of the seat or at the second side 124 of the seat 110. Referring now to FIG. 8, illustrated are alternative exemplary louver assemblies 174a-174c for use with different seat arrangements.

[0069] The fluid delivery system 154 of FIGS. 9-12 is adapted to be mounted between a first adjacent seat 110a and a second adjacent seat 110b (FIG. 1). The fluid delivery system 154 of FIGS. 9-12 is includes a first air outlet 166a in the airflow path and a second air outlet 166b in the airflow path. The first air outlet 166a is arranged to direct a portion of the air moved by the axial fan 172 to a user on the first adjacent seat 110a. The second air outlet 166b is arranged to direct a portion of the air moved by the axial fan 172 to a user on the second adjacent seat 110b.

[0070] The exemplary head 108 of FIGS. 9-12 includes a first louver assembly 174a positioned at the first air outlet 166a and a second louver assembly 174b positioned at the second air outlet 166b. The first louver assembly 174a is arranged to direct air from the airflow path through the first air outlet 166a towards the first user seat 110a. The second louver assembly 174b is arranged to direct air from the airflow path through the second air outlet 166a towards the second user seat 110b. Referring to FIGS. 8 and 12, a divider 190 is positioned in the airflow path 162, wherein the airflow path 162 has a combined upstream portion 192a that extends between the air inlet 164 and the divider 190, a first downstream portion 192b that extends between the divider 190 and the first air outlet 166a, and a second downstream portion 192c that extends between the divider 190 and the second air outlet 166b.

[0071] Alternatively, an airflow path 162 may be arranged to direct air to only a single adjacent seat 110 (e.g., for use at a lateral end of a seat bank). Referring again to FIG. 8, the exemplary heads 178a and 178b each include only a single louver assembly 174. The exemplary head 178a of FIG. 8 includes the first louver assembly 174a for use at the second side 124 of a seat 110. The exemplary head 178b of FIG. 8 includes the second louver assembly 174b for use at the first side 122 of a seat 110.

[0072] In accordance with an aspect, a fluid delivery system includes a liquid flow path. The liquid flow path includes a liquid delivery nozzle operable to deliver liquid. The liquid deliver nozzle may be adjacent an air outlet. Expelled air from the air outlet may cooperate with expelled liquid from the liquid delivery nozzle to carry the expelled liquid toward the user.

[0073] Referring to FIG. 8, the exemplary fluid delivery system 156 includes a liquid delivery nozzle 200. The liquid delivery nozzle 200 is operable to output liquid (e.g., water or a scented liquid). In some examples the liquid delivery nozzle 200 is a mist nozzle operable to expel the liquid as a mist. The liquid delivery nozzle 200 is arranged to direct the liquid towards a region forward of an expected user position of the user seated in the user seat 110. It will be appreciated that the liquid delivery nozzle 200 is at the outlet end of a liquid flow path 202, such as a path through water tube. A liquid moving member such as a pump may be in the liquid flow path to move liquid through the liquid flow path. Also, or alternatively, the liquid may be delivered to the liquid flow path under pressure. In some examples, the liquid flow path 202 includes a valve to control delivery of the liquid to the nozzle.

[0074] Water and scent effects delivered by the liquid nozzle may utilize the air stream to be directed towards the users. The liquid delivery nozzle 200 may be adjacent an air outlet whereby when the fan unit is operating to expel air through the air outlet, the expelled air generates a region of low pressure that draws the liquid towards the user. The exemplary head 178a of FIGS. 8-12 includes the liquid delivery nozzle 200 adjacent a louver assembly 174.

[0075] Referring now to FIG. 10, in some examples, the fluid delivery system 154 includes a first liquid delivery nozzle 200a adjacent to the first air outlet 166a, wherein the first liquid delivery nozzle 200a is operable to output liquid towards a first region of the first user seat 110a and a second liquid delivery nozzle 200b adjacent to the second air outlet 166b, wherein the second liquid delivery nozzle is operable to output liquid towards a second region of the second user seat 110b. The first and second nozzles 202a, 202b may open from a common liquid flow path (e.g., a path branching towards the two nozzles) or from separate liquid flow paths (e.g., independently controllable).

[0076] It will be appreciated that a fluid delivery system 156 may alternatively be provided with only an air flow path. For example, a head 178 may include only an air flow outlet 166 or outlets 166a and 166b (i.e., without any nozzle 200). Exemplary head 178d of FIG. 8 includes first and second air flow outlets 166a and 166b and no liquid delivery nozzles 200.

[0077] In some examples, the fluid delivery system 156 is communicatively coupled to a user occupancy sensor. A fluid flow path may be active only when the user occupancy sensor detects a user in a seat towards which the flow path is directed. For example, an air flow path and/or liquid delivery nozzle may be active only when the user occupancy sensor detects a user in cooperating seat. The user occupancy sensor may be included as part of the armrest 140. In some examples, the user occupancy sensor includes the photoelectric sensor switch 226.
