A lap expanding reactionary airbag apparatus includes separate expanding lap and chest portions of the airbag. When loaded in a frontal or oblique crash event, the two portions act as a reactionary surface against each other, reducing the chest velocity of a vehicle occupant, thereby reducing the forward movement of the occupant. This restriction in forward movement results in reduced lumbar injuries.

An aircraft seat backrest with a lifesaving function, including a backrest body and a back plate assembly, wherein a containing cavity is arranged in a front face of the backrest body, the back plate assembly includes a back plate covering the containing cavity and a lifesaving parachute pack that is arranged on a back face of the back plate and contained in the containing cavity, the back plate is fixedly connected with the backrest body through a quick release mechanism in a quickly separable manner, lifesaving straps of the lifesaving parachute pack pass through strap through holes in the back plate, and an occupant leans against the back plate and is connected with the back plate and the lifesaving parachute pack through the lifesaving straps when riding.

Multi-chamber airbag systems for use in aircraft and other vehicles are described herein. In some embodiments, an occupant restraint system includes a multi-chamber airbag that deploys from an occupant restraint (e.g., a lap seat belt) in an aircraft. The multi-chamber airbag can include a first portion that inflates generally upward in front of the occupant's torso, and a second portion that inflates in front of the first portion. The first portion and/or the second portion can include multiple chambers (e.g., generally cylindrical-shaped chambers) that, when inflated, provide the airbag with a shape and/or contact surfaces which can help to maintain the position of the airbag between the occupant and a strike object or hazard. In other embodiments, multi-chamber airbags configured in accordance with the present disclosure can me mounted to a structure (e.g., a monument, console, seat back, etc.) positioned generally in front of the occupant. The structure-mounted airbag can deploy generally toward the occupant in the event of a vehicle impact or other potentially harmful event to protect the occupant from impact injury.

Vehicle occupant restraint systems that include a compact, web-mounted airbag that can be deployed during a crash event are described herein. In some embodiments, the web (e.g., a shoulder belt) passes through the stowed airbag during normal use and, when the airbag inflates and deploys, the airbag extends along the length of the web (for example, along the entire length, or at least most of the length, of the web) to protect the occupant. In some embodiments, the restraint systems include shoulder belts having first and second overlapping web portions, and when the airbag inflates and deploys, the airbag extends along the length of the first web portion between the first web portion and the second web portion.

An inflatable pillow, having a predetermined shape when inflated, such that the bottom face of the pillow sits securely on an airplane table tray, the pillow's back face, above the arm space, leans fully against the seat back that the table tray is mounted on, providing lateral stability for the upper region of the pillow, unique over the prior art, and an angled front face upon which the confined traveler can lean forward from their seated position and get full support for their upper torso and head so they can comfortably rest or sleep. The pillow is composed of flexible, air-retentive material and has a valve for inflating and deflating the pillow. In its deflated state the pillow is compact enough to fit in most carry-on bags for ease of transport and storage. A simple bellows is provided with the pillow for inflating the pillow. An arm space is provided behind the pillow along the table tray for the users forearms to be folded there, allowing the user to lean onto the front face of the pillow and hug the pillow, providing physical and psychological security for the passenger.

Structure mounted airbag assemblies and associated systems and methods are described herein. An airbag system configured in accordance with an embodiment of the present disclosure can include, for example, a housing having a cavity and an opening in communication with the cavity, an airbag assembly within the cavity, and an inflator operably coupled to the airbag assembly. The airbag assembly can include an airbag configured to deploy through the opening of the housing during a crash event. The airbag system can further include a door removably positioned across the opening and configured to move away from the opening during airbag deployment. The housing can be affixed to an interior portion of an aircraft, forward of and offset from an aircraft seat.

A protective cover that is resistant to absorption and transfer of heat resistant to shocks and penetration of sharp objects and damping shocks at the events, Which combined with the seat fully covers the passenger, and protects him/her against shocks, burns and sharp objects in accidents and is searchable by location-finders.

Various embodiments of vehicle occupant safety systems having extendable restraints for use with, for example, airbags are described herein. In one embodiment, for example, the disclosed technology includes a 2-point occupant restraint that secures an occupant in an aircraft seat. In this embodiment, the aircraft seat is positioned in a seating area that includes a forward monument housing a stowed airbag. In the event of a crash or other significant dynamic event that causes, for example, a rapid deceleration of the aircraft above a preset magnitude, the airbag deploys between the occupant and the monument as the dynamic forces cause the occupant to pitch forward. The forward momentum of the occupant's body creates a significant tension load in the 2-point restraint, which causes the restraint to extend by a preset amount, thereby allowing the occupant to move forward in the seat more than the occupant would have moved had the occupant been wearing a conventional, non-extending 2-point restraint. Although the occupant is allowed to move forward, the occupant remains secured to the extended restraint by means of non-extending webbing that is secured around the waist of the occupant. Allowing the occupant to move forward in this manner enables the occupant's upper torso to impact the airbag at a reduced or otherwise more favorable angle. This can reduce both the speed and the angle at which the occupant's head impacts the airbag, thereby reducing the likelihood of injury.

A divan for installation in an aircraft cabin in relation to an emergency exit. In embodiments, the divan includes at least two seats wherein one seat is positioned directly in front of the emergency exit and includes a lower frame assembly and an upper frame assembly. The upper frame assembly includes a seat pan subassembly configured to raise and lower relative to the lower frame assembly, and a backrest subassembly rotatably attached to the seat pan subassembly. In use, the backrest rotates to a position overlaying the seat pan subassembly and the seat pan subassembly lowers toward the floor to achieve a step-up height of not more than 20 inches to comply with the step-up height requirements for a Type-III emergency exit.
