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.

An apparatus for dynamically tilting a seatpan in an aircraft passenger seating assembly includes a seat frame, seatback, seat cushion, and cushion support structure (e.g., a seatpan), the seat cushion and seatpan together having a forward end and a rear end and together supporting a passenger occupying the seating assembly. Accelerometers may detect an inertial event such as a rapid deceleration that may cause the passenger to pitch forward; dynamic seatpan actuators (e.g., airbags or ballistic devices) connected to the accelerometers react to the inertial event by detonating, driving the seatpan and seat cushion upward. As a result, the head path of the passenger may be redirected upward, alleviating the risk of passenger injury and component damage. Additional airbags may react to the inertial event by tightening the passenger seatbelt.

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 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.

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.

An airbag system for a vehicle table is provided. The system includes a table disposed in front of a passenger and an airbag cushion that is provided inside the table. The airbag cushion expands while being deployed in a state in which a first end portion of the airbag cushion is fixed to an internal portion of an edge of the table to allow a second end portion to protrude above the table and to cover an upper surface of the table. The airbag cushion also includes a bottom surface portion that faces the table, which is positioned at an interval from the upper surface of the table while the airbag cushion is deployed. An inflator supplies gas to the airbag cushion to deploy the airbag cushion.

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.

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.

An airbag system for a vehicle table is provided. The system includes a table disposed in front of a passenger and an airbag cushion that is provided inside the table. The airbag cushion expands while being deployed in a state in which a first end portion of the airbag cushion is fixed to an internal portion of an edge of the table to allow a second end portion to protrude above the table and to cover an upper surface of the table. The airbag cushion also includes a bottom surface portion that faces the table, which is positioned at an interval from the upper surface of the table while the airbag cushion is deployed. An inflator supplies gas to the airbag cushion to deploy the airbag cushion.
