An aircraft that includes a body that defines a cabin interior, front and back rows of seats positioned in the passenger zone, a forward door that is pivotable between a closed position and an open position, and an aft door that is pivotable between a closed position and an open position. The cabin interior includes a pilot zone, a passenger zone positioned aft of the pilot zone, and a cargo zone positioned aft of the passenger zone. The pilot zone and the front row of seats are accessible and the back row and cargo zone are inaccessible from an exterior of the body when the aft door is in the closed position and the forward door is in the open position. The back row and cargo zone are accessible and the pilot zone and the front row of seats are inaccessible from the exterior of the body when the aft door is in the open position and the forward door is in the closed position.

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 conformal seat insert for an adjustable vehicle seat, the conformal seat insert comprising an insert frame, the insert frame having one or more insert reference features for locating the insert frame on a seat frame of the vehicle seat in a predetermined position relative to the seat frame, and a contoured support surface formed in the insert frame, the contoured support surface having a crew reference point corresponding to an acromial point of a shoulder of a seat occupant of the adjustable vehicle seat, the crew reference point being a datum from which an eye position of the seat occupant is established relative to instrumentation of an aerospace vehicle in which the adjustable vehicle seat is located.

Web pretensioning system devices for increasing the amount of web retracted by a given pretensioning stroke are disclosed. In some embodiments, the disclosed web pretensioning systems can include a pretension multiplier configured to receive a web of an aircraft passenger seat occupant restraint system. The pretension multiplier can include a web guide and a web coupling that is operably connected to a pretensioner. In operation, the pretensioner rapidly pulls or otherwise moves the web coupling away from the web guide a first distance, thereby retracting a loop of the web through the web guide. As a result of retracting the loop of web through the web guide, the overall retracted length of the web is equal to a second distance that is greater than the first distance.

An adaptive belt is attached to a vehicle seat and includes a first section (101), a second section (102), and a third section (103). The adaptive belt includes a retracted configuration and a fully extended configuration. In the retracted configuration, the adaptive belt is folded between the first section and the second section such that a first attachment attaches the first section to a first portion of the second section. In the retracted configuration, the adaptive belt is also folded between the second section and the third section such that a second attachment attaches a second portion of the second section to a first portion of the third section. In the fully extended configuration, all of the attachments fail thereby increasing a length of the adaptive belt. In response to a threshold loading condition, the adaptive belt changes from the retracted configuration to the fully extended configuration.

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.

Disclosed is a modular seat for aircraft. The system has a frame that is able to be interconnected with other frames laterally. Since each lateral frame has the same pivot points (when viewed from the side), the linked seats rotate together. The seats also include buckle lugs which enable a particular seat to be used on either side of the aircraft.

An aircraft passenger seat including decoupled seat back and seat bottom elements configured to be selectively positioned with respect to spaced seat elements to allow the seat to be used for seating or storage as desired. The passenger seat is convertible by repositioning the seat back and seat bottom elements to provide conventional forward-facing seating, face-to-face seating with a longitudinally aligned and adjacent seat, or seat storage as desired. The seat back and seat bottom elements track along a track assembly affixed along facing inboard sides of fixed seat elements such as arm rest assemblies.

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.

A safety seat for an occupant includes a front shell secured to a bulkhead. The front shell has an outer edge and an inner edge. The inner edge defines an opening. The safety seat includes a seat base having a first side and a second side opposite the first side. The seat base has a first position and a second position. In the first position, the first side is flush with the inner edge and in the second position; the second side supports the occupant.
