Disclosed is a personal flying machine using compressed air as power source, and an operation method thereof, the flying machine including a stationary rotor lift device in a cyclone duct, a seat frame and a compressed air supply device; wherein the stationary rotor lift device in a cyclone duct includes a cyclone duct, in-duct stationary rotors and in-duct compressed air artificial wind blowing ports; wherein the in-duct stationary rotor includes a stationary propeller hub and a plurality of stationary blades fixed connected around the stationary propeller hub and arranged radially; wherein the stationary blade is shaped as an airplane's wing having an airfoil, an angle of attack, a leading edge and a trailing edge; wherein the compressed-air supply device supplies compressed air to the in-duct compressed-air artificial wind blowing ports to eject airflows towards the leading edges of the stationary blades and form a cyclone to generate lift. The present application solves the problems of efficiency limitation, high cost, heavy structure and energy-environment issues related to the traditional personal flying machines of burning fossil fuels to do work, and overcomes their shortcomings and problems with the wingless or wing-movement to generate lift in relatively static air.

A passenger seat having a frame is proposed, wherein the frame is intended for securing to a floor of a passenger cabin, wherein the frame comprises a seat divider and beams that run transverse to the seat direction, wherein the seat divider is held by the beams, wherein a housing is disposed on the seat divider, wherein the housing at least partly surrounds a backrest. According to the invention, a structure component is disposed on the seat divider, with an attachment unit for a safety belt for a passenger disposed on the structure component.

The invention relates to a safety belt, which is in particular intended to be installed in an aircraft seat, comprising: a closing loop comprising a male element and a female element, a first strap which is connected to the male element and a second strap which is connected to the female element, the first strap and the second strap being capable of being attached together by means of the closing loop, which can change from an open state to a closed state through cooperation between the male element and the female element, the safety belt further comprising: a system for detecting that the safety belt is in the closed stated, the system being capable of generating an information item relating to a closed state of the safety belt, and a system for detecting that the safety belt is in a mechanically tensioned state, said system being capable of generating an information item relating to a mechanically tensioned state of at least one strap of the safety belt.

A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, receives sensor data from a plurality of sensors in an aircraft cabin; and employ an artificial intelligence (AI) program to train on input data comprising at least one of safety compliance data, aircraft system data, cabin environment data, cabin operations data, or aircraft operations data; and the AI program is configured to minimize a summed error of predictions of seatbelt compliance.

A seat usage prevention device is disclosed. The seat usage prevention deice includes at least one device component being configured to interact with one or more seat components of a first seat. The device component is configured to prevent usage of at least one of a seat pan or seatback of the first seat. The device component further separates a second seat from at least a third seat, wherein the third seat is proximate to at least one of the first seat or the second seat. The seat usage prevention device may include a device component that further includes a cushion, a base, an amenity console, or a vertical separator, or combination thereof.

A modal restraint system for an occupant of a seat of an aircraft. The modal restraint system includes a strap feeder unit and a strap selectively retractable into and extendable from the strap feeder unit. The strap feeder unit is adapted to switch between a plurality of modes including an unfixed mode and a fixed mode. The strap is extendable from and retractable into the strap feeder unit in the unfixed mode. The strap is substantially unextendable from the strap feeder unit in the fixed mode. The strap feeder unit is in the unfixed mode by default. The strap feeder unit is operable to switch from the unfixed mode to the fixed mode in response to a precautionary event including detection of an operational parameter that is beyond a predetermined threshold, thereby reducing freedom of movement of the occupant relative to the seat.

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 stowable cabin attendant seat assembly includes a frame assembly mountable within a wall recess, a backrest mounted for reciprocating vertical translation within the frame assembly, a seat pan mounted for pivoting motion relative to the frame assembly, and at least one link connecting the seat pan to the backrest. The at least one link coordinates the seat pan and backrest motions such that upward lifting motion on the seat pan pushes the backrest vertically up for compact stowing and downward pivoting motion on the seat pan pulls the backrest vertically down.

A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, generates a time-based record of the safety-compliance data. The computer system can use the time-based record to adapt cabin operations policy, including cabin temperature, cabin lighting, illumination of seatbelt signs, scheduling of meal or drink service, timing of inflight announcements, or the availability of in-flight entertainment.

A vertical take-off and landing (VTOL) aircraft provides transportation to users of a network system. The network system may include multiple aircraft or other types of vehicles to provide multi-model transportation. An aircraft may include a fuselage, a truss coupled to the fuselage, and multiple distributed electric propellers coupled to the truss. The distributed electric propellers may be positioned on at least two different planes. The fuselage may include a cabin having one or more seats for the passengers arranged in a configuration that has a compact footprint, provides legroom, provides visibility to surroundings of the aircraft, or facilitates convenient ingress or egress of passengers. The aircraft may open a port cabin door and starboard cabin door for simultaneous ingress or egress of passengers.
