DETAILED DESCRIPTION

[0008] The present disclosure describes various embodiments of airbag assemblies for use with fixed structures (e.g., seat backs, partitions, etc.) of a vehicle (e.g., aircraft). In some embodiments, the airbag assembly can include an airbag configured to inflate and deploy in front of a seat occupant to provide a cushioning barrier between the occupant and, e.g., a strike hazard. In some embodiments, the airbag assembly is stowed in a portion of a seatback or partition in front of the occupant on an aircraft. A conduit extends from the stowed airbag to an inflator that can be mounted under the seat or in another suitable location. If the aircraft experiences an accident or other significant dynamic event (e.g., a rapid deceleration event) in which the occupant could be thrown forward against a strike hazard, the inflator rapidly releases compressed gas into the airbag via the conduit, causing the airbag to rapidly inflate and deploy in front the occupant.

[0009] As described in greater detail below, in some embodiments the airbag assembly includes a mounting structure or member (e.g., a plate, bracket, etc.) configured to be attached to a fixed structure (e.g., a seat back, wall, partition, etc.), an airbag attached to the mounting member, and a sleeve attached to or proximate the mounting member. The sleeve can surround at least a portion of the airbag in the stowed position. During deployment of the airbag, the sleeve can be configured to unravel in a manner that covers an opening, gap or other feature created by an adjacent structure, device or component (e.g., an entertainment module, tray table, etc.) that is adjacent the airbag assembly. Accordingly, the sleeve, and its positioning around the airbag, can prevent the airbag from deviating from the desired deployment path and getting hung up on the adjacent feature during deployment. Stated differently, the sleeve can help ensure that the airbag properly deploys to protect the occupant seated behind the airbag. Although referred to herein as a fixed structures for ease of reference, it will be understood that aircraft passenger seats that recline and/or move in other ways are nevertheless fixed structures for purposes of the present disclosure.

[0010] Certain details are set forth in the following description and FIGS. 1-4C to provide a thorough understanding of various embodiments of the disclosure. For example, several embodiments of airbag assemblies are described below in the context of commercial aviation aircraft. However, the airbag assemblies and aspects thereof disclosed herein may be used in a wide variety of other vehicles, including other aircraft (e.g., general aviation and military aircraft), ground vehicles (e.g., automobiles, trucks, buses, trains, and motor homes), watercraft, etc. To avoid unnecessarily obscuring the description of the various embodiments of the disclosure, some details describing well-known structures and systems often associated with airbags, related circuitry, inflators, etc., have not been described in detail below.

[0011] Furthermore, many of the details, dimensions, angles and other features shown in FIGS. 1-4C are merely illustrative of particular embodiments of the disclosure.

[0014] FIG. 1 is a partially schematic top isometric view of an airbag assembly 105 mounted to a fixed structure 100 in an aircraft seating area, configured in accordance with embodiments of the present technology. As shown in FIG. 1, a rear portion of the fixed structure 100 (e.g., a passenger seat) supports a cover panel 110 (e.g., a flap or door) disposed over the airbag assembly 105, and a component 115 (e.g., an entertainment module, display screen, tray table, etc.) positioned below the airbag assembly 105. The fixed structure 100 can be a passenger seat (as shown in FIG. 1), or other structure such as a wall, partition, etc. in front of or adjacent to a passenger 120 seated behind the structure 100. As described in more detail below, the airbag assembly 105 can be configured to deploy in front of the component 115 to prevent the passenger 120 from striking the component 115 during a crash or other rapid deceleration event.

[0015] FIG. 2 is a partially schematic isometric view of the airbag assembly 105 of FIG. 1 in a stowed configuration in accordance with embodiments of the present technology. The cover panel 110 and associated hardware has been omitted from FIG. 2 for purposes of illustration. In some embodiments, the airbag assembly 105 is positioned within a recess in the structure 100 above the component 115. The airbag assembly 105 can include a mounting bracket 210, an airbag 225 attached to the mounting bracket 210, and a sleeve 230 surrounding at least a portion the airbag 225. The sleeve 230 can be made of a flexible and/or bendable fabric material (e.g., woven nylon) or other suitable materials known in the art. The mounting bracket 210 can be formed from a suitable sheet metal and can include a plate portion 212, a first flange portion 214 extending upwardly from the plate portion 212 at an angle (e.g., between about 20 to about 160), and a second flange portion 216 extending downwardly from the plate portion 212 at an angle (e.g., between about 20 to about 160). The plate portion 212 can include a plurality of first fastener openings 218, and the first flange portion 214 can include a plurality of second fastener openings 220.

[0016] As described in greater detail below, the airbag 225 is configured to be inflated from the stowed configuration shown in FIG. 2 to a deployed configuration as shown in FIGS. 4B and 4C. For airbag deployment, the airbag assembly 105 includes a hose or conduit 250 operably coupled to the airbag 225 and configured to deliver gas thereto. The conduit 250 can include tubing made from stainless steel or another suitable material that enables high pressure gas to flow from an inflator 252 to the airbag 225. In some embodiments, the conduit 250 can be a flexible fabric hose made from nylon or other suitable materials known in the art (e.g., Kevlar, polyurethane, etc.).

[0017] In some embodiments, the airbag assembly 105 further includes an electronics assembly 254 (shown schematically) operatively connected to the inflator 252 via a corresponding electrical link 253 (e.g., a wire, electrical line, retractile cord, connector, wireless communication link, etc.). The electronics assembly 254 (e.g., an electronics module assembly (EMA)), can include one or more sensor(s) 256 (e.g., a crash sensor, an acceleration sensor, a magnetic field sensor, etc.) and associated devices and circuitry configured to detect a rapid deceleration event above a preset magnitude, and transmit one or more corresponding signals to the inflator 252 via the electrical link 253 to initiate deployment of the airbag 225. During deployment of the airbag 225, high pressure gas flows from the inflator 252 to the airbag 225 via the conduit 250.

[0018] The inflator 252 can include a canister, cylinder, and/or other container filled with air or a substantially inert compressed gas (e.g., nitrogen, helium, argon, etc.). The gas can be released by a spike in internal pressure caused by a pyrotechnic, electric, or other initiation device that is activated by an electrical signal from the electronics assembly 254 in response to a crash, rapid deceleration event, or similar dynamic event above a preset level of deceleration. In other embodiments, the inflator 252 can include a propellant-based gas generating device and/or other gas sources suitable for airbag inflation.

[0019] As schematically illustrated in FIG. 2, the electronics assembly 254 can include a microprocessor 260 that receives electrical power from a power source 262 (e.g., one or more batteries). The one or more sensor(s) 256 can detect a rapid deceleration event and communicate this event to the microprocessor 260. For example, in operation, when the sensor(s) 256 detects a rapid deceleration or other crash event above a preset magnitude, one or more switches in the sensor(s) 256 can close and cause the microprocessor 260 to send a corresponding signal to a deployment circuit 258. Upon receiving the signal from the microprocessor 260, the deployment circuit 258 transmits a signal to the inflator 252 via the electrical link 253 to initiate deployment of the airbag 225 by discharging gas into the airbag 225 via the conduit 250.

[0020] FIG. 3A is a top isometric view of a portion of the airbag assembly 105 of FIG. 1 in a first stage of assembly, FIG. 3B is a side view of a portion of the airbag assembly 105 shown in FIG. 3A, and FIG. 3C is a side view of the airbag assembly 105 in the stowed configuration. In FIGS. 3A and 3B, the airbag 225 is extended generally flat and is not in the stowed configuration. As described above with the reference to FIG. 2, the airbag assembly 105 can include the airbag 225 and the sleeve 230 attached to the mounting bracket 210. As shown in FIG. 3A, the mounting bracket 210 can be attached to the fixed structure 100 (FIG. 1) with a plurality of fasteners 322 (e.g., rivets, screws, etc.) that extend through the second flange portion 216 and a plurality of fasteners 323 (e.g., rivets, screws, etc.) that extend through plate portion 212.

[0021] Referring to FIGS. 3A and 3B together, the airbag assembly 105 can further include a cap strip 330 configured to clamp and thereby attach a first end portion 331 of the airbag 225 and a first end portion 326 of the sleeve 230 to the mounting bracket 210. The cap strip 330 can include an elongate plate (e.g., a metal plate) having a plurality of openings along a length thereof. A plurality of fasteners 340 (e.g., rivets, screws, bolts, etc.) or other fixation devices can extend through the openings in the cap strip 330, the sleeve 230, the airbag 225 and the corresponding openings 218 in the mounting bracket 210 to thereby attach the cap strip 330, the sleeve 230 and the airbag 225 to the mounting bracket 210.

[0022] After securing the sleeve 230 and airbag 225 to the mounting bracket 210, the airbag 225 can be folded or rolled upon itself in a direction indicated by fold (F.sub.1) in FIG. 3A until the airbag 225 is in the stowed configuration shown in FIG. 3C. Once the airbag 225 is in the stowed configuration, the sleeve 230 can be wrapped around the airbag 225 in a direction indicated by fold (F.sub.2) in FIG. 3A, and the second end portion 327 of the sleeve 230 can be releasably attached to the first flange portion 214 of the bracket 210 by a plurality of fasteners 350 (e.g., rivets, screws, etc.) as shown in FIG. 3C. As explained in further detail below, the sleeve 230 can be releasably coupled to the flange 214 by the fasteners 350 so that the sleeve 230 can be easily detached from the flange 214 upon deployment of the airbag 225.

[0023] FIGS. 4A and 4B are side views of the airbag assembly 105 attached to the structure 100 in accordance with embodiments of the present technology. FIG. 4A shows the airbag assembly 105 with the airbag 225 in the stowed configuration, and FIG. 4B shows the airbag assembly 105 with the airbag 225 in the deployed configuration. As shown in FIG. 4A, the fixed structure 100 includes a rear surface portion 406, and the component 115 (e.g., an entertainment screen) is attached to the rear surface portion 406 and defines a gap or opening (0) therebetween. The airbag assembly 105 is generally positioned above the opening (0) and includes (a) the mounting bracket 210 attached to the fixed structure 100 via the fasteners 323, 322, (b) the airbag 225 in the folded and packed configuration, and (c) the sleeve 230 disposed at least partially around the airbag 225. The airbag 225 and the first end portion 331 of the sleeve 230 are attached to the mounting bracket 210, and thus to the fixed structure 100, via the fasteners 340. Furthermore, the second end portion 327 of the sleeve 230 is releasably attached to the mounting bracket 210 via the fasteners 350. In other embodiments, the second end portion 327 of the sleeve 230 may not be attached to the mounting bracket 210 via the fasteners 350. For example, in such embodiments the second end portion 327 may be tucked between the mounting bracket 210 and the adjacent portion of the airbag 225.

[0024] The cover panel 110 can include a first edge or end portion 462 releasably attached to the mounting bracket 210 and/or the adjacent structure 100 via one or more releasable fasteners, adhesive, etc. (not shown). The cover panel 110 can further include a second edge or end portion 463 supported by a bracket 480 mounted to the rear surface portion 406. As shown in FIG. 4A, the cover panel 110 and the bracket 480 together can enclose the airbag 230. The cover panel 110 can be made of a relatively durable material, such as a hard plastic, aluminum, or combinations thereof.

[0025] As described in more detail below with reference to FIG. 4B, the cover panel 110 can be releasably attached to the mounting bracket 210 and/or the fixed structure 100 and configured to be displaced during airbag deployment so as to not impede the airbag 225 from inflating to the deployed state. In some embodiments, the cover panel 110 can be attached to the mounting bracket 210 and/or the fixed structure 100 (and/or to the sleeve 230) by a strap or tether 466 that restrains the cover panel 110 during displacement. The tether 466 can be made of a strip of flexible and/or bendable fabric material, such as nylon or other suitable materials known in the art. In some embodiments, a first end portion of the tether 466 can be attached to the mounting bracket 210, and a second, opposing end portion of the tether 466 can be attached to the cover panel 110 at or near the second end portion 463. During airbag deployment, the tether 466 can help ensure the cover panel 110 does not become a hazardous flying object to the occupant 120 (FIG. 1). In other embodiments, the first end portion 462 of the cover panel 110 can remain coupled to or near the first flange portion 214 of the mounting bracket 210 during airbag inflation, and the cover panel 110 can be configured to bend upwardly and away from the deployment path of the airbag 225 so that it does not impede the airbag 225 from inflating to the deployed state.

[0026] FIG. 4B shows the airbag system 400 with the airbag 225 inflated to the deployed configuration. As previously described, the airbag 225 can be inflated via compressed gas that is released from the inflator 252 (FIG. 2) and passes through the conduit 250 (FIG. 2) to the airbag 225. In operation, the inflating airbag 225 pushes the cover panel 110 and the second end portion 327 of the sleeve 330 away from the structure 100 and detaches the second end portion 327 of the sleeve 330 from the mounting bracket 210. The airbag 225 and the first end portion 326 of the sleeve 230 remain attached to the mounting bracket 210 during and after deployment of the airbag 225. As a result, the sleeve 330 unravels to be disposed between the airbag 225 and the opening (0) and/or the component 115. Stated differently, the sleeve 330 is positioned around the stowed airbag 225 such that deployment of the airbag 225 causes the sleeve 330 to detach from the first flange 214 of the mounting bracket 210 and cover the opening (0) and/or the component 115. By covering or otherwise extending over the opening (0) and/or the component 115, the sleeve 330 can prevent the airbag 225 or a portion thereof from inflating into or toward the opening (0) and potentially getting hung up on an edge portion of the component 115, with could undesirably impede proper inflation of the airbag 225. As shown in FIG. 4B, the tether 466 remains attached to the cover panel 110 even after deployment of the airbag 225 to prevent the cover panel 110 from flying away from the structure 100.

[0027] FIG. 4C is a top isometric view of the deployed airbag 225 of 4B. Referring to FIGS. 4B and 4C together, the deployed airbag 225 includes a rear face portion 432a facing toward the seat occupant 120 (FIG. 1), and a front face portion 432b (FIG. 4B) having a vent 434 (e.g. a hole). The vent 434 allows gas to rapidly escape from the airbag 225 after inflation. In some embodiments, the vent 434 can help limit rebound of the occupant from the airbag 225 and rapidly deflate the airbag 225 to allow egress for the occupant shortly after inflation.
