An electronic module assembly for controlling the deployment of one or more airbags in an aircraft includes a power source, a crash sensor configured to produce a signal in response to a crash event and an accelerometer that is configured to produce a signal in response to a crash event. A processor starts a timer upon detection of the signal from the crash sensor. When the processor receives a signal from the crash sensor, the processor is configured to determine if a signal has also been received from the accelerometer and if signals from both the crash sensor and the accelerometer indicate a crash event then the processor reads a memory associated with an inflator. The processor reads a timing value selected for the inflator and fires the inflator when the timer has a value equal to the timing value selected for the inflator.

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.

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.

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.

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.

In a triggering system for activating a safety device, an acceleration sensor outputs a signal for a time duration in which an acceleration impulse exceeds an acceleration magnitude threshold. A first switching device receives the signal output by the acceleration sensor, and electrically connects a power supply to at least one safety response device for the time duration. A time delay device, upon completion of a delay time after receiving the signal output by the acceleration sensor, outputs a signal for the time duration. A second switching device receives the signal output by the time delay device, and electrically connects the power supply to the at least one safety response device for the time duration. When the time duration exceeds the delay time, the first switching device and the second switching device concurrently electrically connect the safety response device to the power supply, activating the safety response device.

A safety system includes a safety response device positioned proximal to an aircraft seat. The safety response device is operable to deploy thereby controlling the leg extension condition of legs of an occupant of the aircraft seat. A triggering system is operable to activate the safety response device when a deceleration is detected. The safety response device can be operable to maintain the legs of a seated occupant in an un-extended condition thereby protecting the legs from extending when a rapid deceleration occurs. The safety response device can be operable to transition the legs of a seated occupant from an un-extended condition to an extended condition at a predetermined rate. The safety response device can be, for example, and airbag or a kick plate. The device may automatically return to a stowed condition a predetermined time after deployment to permit egress from the seat and aircraft.

Airbag assemblies having sleeves and other flexible guide members and associated systems and methods are described herein. Airbag assemblies configured in accordance with some embodiments of the present technology can include a mounting bracket configured to be attached to a structure in an aircraft, such as a passenger seat back or a partition wall, adjacent to a component, such as a display screen. The airbag assemblies can further include an airbag and a guide sleeve attached to the mounting bracket. The airbag is configured to be inflated from a packed or stowed configuration to a deployed configuration. In the stowed configuration, the sleeve at least partially surrounds the airbag. Inflating the airbag to the deployed configuration causes the sleeve to extend between the airbag and at least a portion of the adjacent component to prevent the component or an associated opening from interfering with proper deployment of the airbag.

A method for controlling deployment of an airbag relative to ground contact includes retrieving a predicted ground contact time for an aircraft from a crash prediction module, retrieving seat position measurements and occupant data for a seat in the aircraft, and comparing the predicted ground contact time, the seat position measurements and the occupant data to pre-established data to determine a custom airbag deployment time with respect to the predicted ground contact time, for at least one airbag on the aircraft. The method includes sending a signal to deploy the at least one airbag based on the custom airbag deployment time.

An inflatable pod system on an aircraft includes an inflatable pod including a nozzle to receive air for inflation of the inflatable pod, and a hose assembly including a first end having an adaptor fitting that is configured to press fit with an air duct nozzle of an air duct of the aircraft and a second end having an adaptor configured to couple to the nozzle. In an example, the hose assembly delivers bleed air from the air duct, as provided by an environmental control system (ECS) of the aircraft, to the inflatable pod to inflate the inflatable pod. In another example, an air duct assembly line couples the ECS with the inflatable pod, and a control system triggers inflation via the air duct assembly line based on receipt of an electronic inflation signal.
