Embodiments of the present disclosure relate generally to valves that provide controlled inflation. The valves are designed to allow inflation of one or more inflatable devices and to stop inflation once a desired inflation level has been reached. This can allow the valve to be used with a single inflation source in order to inflate a plurality of inflatable devices. In a specific example, this disclosure provides systems and methods for inflating an ejector bag for door-mounted or fuselage-mounted inflatable evacuation slides or slide/rafts used for evacuating passenger vessels, such as aircraft. Other examples relate to sustaining the inflation of individual tubes that communicate with one another in evacuation slides, evacuation slide/rafts, life rafts and/or other inflatable devices.

An adaptive force vehicle airbag (AFVA) system includes airbag(s) stowed in a compressed state within an interior of a vehicle. An impact sensor detects a change in motion of the vehicle indicative of a collision. Selectable force gas generator(s) (SFGGs) gas-generating propellant cells that are individually fired. The SFGGs have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate at least one of the airbag(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the SFGGs. The controller enables the AFVA system to: (i) receive an inflation signal from the impact sensor; and (ii) fire a selected number of the gas-generating propellant cells to at least partially inflate the at least one airbag.

To provide a drone with an airbag that can eliminate the danger of the drone injuring a person in the event of the drone crashing mid-flight including during takeoff and landing. The present invention is equipped with an airbag 3 for reducing the impact of a crashed drone 2 colliding with a person. Prior to the drone 2 taking off, the airbag 3 can be inflated by being supplied with gas. Once the drone 2 has taken off and reached a required altitude, the airbag 3 deflates due to the gas being exhausted. When the drone 2 is mid-flight and in danger of crashing, the airbag 2 can be inflated instantly by being supplied with gas. Prior to the drone 2 landing, the airbag 3 can be inflated by being supplied with gas.

An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a plurality of shock absorbers including a first shock absorber and a second shock absorber different from the first shock absorber, the first shock absorber defining a first gas chamber containing a first gas that is less dense than air; and a release unit that is disposed on the first shock absorber and configured to release the first gas contained in the first gas chamber at a predetermined timing.

An aircraft cabin includes at least one seat able to receive at least one passenger; at least one table arranged opposite the seat; and a safety device able to be mounted on the table, below the table or received in the table. The safety device includes a deployable protection assembly including an airbag deployable from a retracted idle configuration to a deployed safety configuration, and a system for controlling the deployment of the or each airbag, able to trigger the deployment of the airbag beyond a threshold deceleration value of the aircraft.

Airbags for use in aircraft and other vehicles are described herein. In some embodiments, an airbag can deploy from a structure forward of a seated occupant at a generally upward angle relative to a longitudinal axis of the aircraft. The distal end portion of the airbag can include a recessed impact surface portion configured to receive the head and/or neck of the seat occupant.

The present disclosure relates to a cargo protection method, device and system, and a non-transitory computer-readable storage medium, relating to the technical field of unmanned aerial vehicles. The method of the present disclosure includes: determining whether an unmanned aerial vehicle is in a falling state or not according to a current acceleration in a vertical direction of the unmanned aerial vehicle and a current vertical distance from the unmanned aerial vehicle to the ground; and opening at least one airbag in a cargo hold of the unmanned aerial vehicle in a case where the unmanned aerial vehicle is in the falling state to protect a cargo in the cargo hold.

A monument mounted airbag system for arresting passenger movement during a sudden acceleration/deceleration event of a moving vehicle includes an airbag assembly including at least one airbag on a first portion of a monument structure, the airbag assembly having a housing at least partially defined by a space between an external member and the monument structure.

Airbag systems for use in aircraft are described herein. In some embodiments, an occupant restraint system for use with a passenger seat on an aircraft includes an under-seat airbag having a leg restraint portion. The under-seat airbag can be stowed approximate to a seat pan prior to use. In operation, the under-seat airbag can inflate to reduce occupant forward head path excursion and/or forward extension of the occupant's legs during a crash or other rapid deceleration event.

Airbag systems for use in aircraft are described herein. In some embodiments, an occupant restraint system for use with a passenger seat on an aircraft includes an under-seat airbag and a lap belt airbag. The lap belt airbag can be operably positioned on a lap belt configured to be fastened around a seat occupant, and the under-seat airbag can be positioned proximate to a seat pan. In operation, the under-seat airbag and the lap belt airbag can inflate simultaneously, or at least approximately simultaneously, to reduce occupant forward head path excursion during a crash or other rapid deceleration event.
