Systems and methods are provided for inflatable air pads for aircraft. One embodiment is an apparatus that includes an air pad affixed to a mount within an interior of an aircraft. The air pad includes a front face, a bladder that is inflatable within the air pad, and sides that constrain the front face of the air pad to extend a uniform distance outward from the mount when the bladder is inflated. The apparatus also includes an inflator that is coupled with the air pad and is configured to inflate the bladder from an undeployed volume to a deployed volume.

A stowable harness fan assembly for a low-back divan is disclosed. In embodiments, the stowable harness fan assembly includes one or more vertical support members, a horizontal support member, and a repositionable harness fan. The horizontal support member is coupled to the one or more vertical support members. The horizontal support member includes an opening and a pivot disposed at one end of the opening. The repositionable harness fan is coupled to the horizontal support member by the pivot and is at least partially disposed within the opening so that the repositionable harness fan can rotate between an open (e.g., raised) configuration and a closed (e.g., stowed) configuration with respect to the opening.

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.

An electronic module assembly (EMA) for use in controlling one or more personal restraint systems. A programmed processor within the EMA is configured to determine when a personal restraint system associated with each seat in a vehicle should be deployed. In addition, the programmed processor is configured to perform a diagnostic self-test to determine if the EMA and the personal restraint systems are operational. In one embodiment, results of the diagnostic self-test routine are displayed on a display included on the electronic module assembly. In an alternative embodiment, the results of the diagnostic self-test routine are transmitted via a wireless transceiver to a remote device. The remote device can include a wireless interrogator or can be a remote computer system such as a cabin management computer system.

A three-place aircraft divan configured to be installed side-facing in an aircraft and track between an upright sitting position and a berth position. Seat bottom and backrest portions of the divan are movably supported on a static frame and track together. The divan includes inflatable passenger restraints at each seat place and a leg flail prevention device at one end of the frame triggered to actuate in response to an event sensed by a mechanical crash sensor. The inboard leg arrangement of the divan accommodates the installation of two containers for containing high-capacity life rafts under the seat bottom frame, among other equipment.

A seat control system of an air vehicle for urban air mobility (UAM)UAM is provided. When the air vehicle turns strongly to one side during rotor failure of the air vehicle for UAM, side pads and air cells prevent the head and the body of a passenger seated on a seat in the air vehicle from being sharply tilted to the one side. Additionally, air bags of the side pads prevent and cushion impact energy applied to the head of the passenger at the moment when the air vehicle lands on the ground.

Adjustably positionable airbag assemblies and associated systems and methods are described herein. An occupant restraint system configured in accordance with embodiments of the present technology can include, for example, an airbag stowed and carried on a seat belt web of the occupant restraint system in an aircraft. The occupant restraint system can further include a fastening assembly configured to receive a web of the occupant restraint system. In a first mode, the fastening assembly is slidable along at least a portion of the web. In a second mode, the fastening assembly is coupled to the airbag and secured (e.g., clamped) to the web in a selected position. The airbag is configured to inflate in response to a rapid deceleration event and deploy in front of a seat occupant.

This invention relates to any field where crafts (such as avionics) where inhabitants of volumes like passage compartments can be found where the area is subject to extreme conditions such as explosion, fire or other traumatic activity linked with a crash, and more specifically a process and method for the protection of inhabitants or passengers in the volume in the craft using a system for the protection of the inhabitants or passengers in the volume using both an anti-trauma apparatus for blast release of a first chemical within the volume for shock protection and for an anti-explosion apparatus for the blast-release of a neutralizing chemical compound within the fuel tank reservoir in a craft to neutralize the inflammability and explosion capacity of the fuel in the tank to avoid detonations and damage to an adjacent volume.
