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 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.

A protection device having a set of inflatable protection members including a neck airbag, a left lower airbag, a left upper airbag, a right lower airbag, and a right upper airbag. The protection device has a lower pocket provided with a lower base forming the neck airbag and two lower lateral branches forming the left lower airbag and the right lower airbag. An upper pocket at least partially secured to the lower pocket is provided with an upper base forming a head airbag and two upper lateral branches forming the left upper airbag and the right upper airbag. At least one longitudinal internal wall provide at least two “tubes” in each upper airbag, the upper pocket being in fluid flow communication with the lower pocket.

The invention provides a cover for an aircraft passenger using a bed surface of an aircraft passenger seat, comprising an attachment mechanism for attaching the cover to the seat, an inflatable bladder, and a trigger mechanism for triggering inflation of the bladder, the bladder being configured to cover a knee region of the bed surface. The invention also provides a harness for the aircraft passenger, comprising an attachment mechanism for attaching the harness to the seat, a number of straps for extending around the passenger, and a fastening mechanism for fastening one or more of the straps in place around the passenger, wherein the number of straps includes at least one of a crotch strap and a torso strap. The invention also provides an aircraft passenger seat unit comprising a seat convertible to a bed, the bed being provided with a cover or harness.

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.

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.

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.

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.

Occupant restraint systems for use in aircraft and other vehicles are described herein. In some embodiments, the occupant restraint systems include an under-seat airbag positioned below a seat cushion having a separation feature extending laterally therethrough. The separation feature enables a front cushion portion to move upwardly and away from a seat pan by a greater distance than a rear cushion portion upon inflation of the under-seat airbag, thereby favorably positioning the seat occupant's thighs relative to the seat occupant's torso.

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.
