Abstract: A seat unit and a lower structure thereof that are not restricted in their positional relationship with seat tracks provided in advance in the airframe. One representative seat unit of the present invention and the lower structure thereof includes a hollow structure integrally formed using a composite member. The hollow structure is hollow in a front direction of the seat unit. The hollow structure has a quadrilateral shape in the front direction of the seat unit. In addition, a partition plate is disposed in the hollow structure. Furthermore, the lower structure includes attachment points to an aircraft at three locations on its bottom. In addition, a block is embedded in the composite member at the attachment point, and a thickness of the composite member around a bracket coupled to the block is less than thickness at other locations.

Abstract: In order to improve ease of maintenance of an aircraft passenger seat, the aircraft passenger seat 100 is adapted to be changeable between an upright position and a bed mode position at which the backrest is folded forward. A mechanism for locking the seat at each of the positions is provided with lock pins 350 provided on both sides of the backrest, a handle unit 200 mounted to a rear face of the backrest, and two wires 300 for connecting the handle unit 200 and the lock pins 350. A structure for connecting the wires 300 to the handle unit 200 is improved to facilitate the maintenance of the wires and to make the handle unit lightweight.

Abstract: An aircraft passenger seat (100) is fixed to a floor via a seat track fitting (110), and a reclining assembly of the seat is supported by pipes (130, 132) passed through left and right legs (120) and spreaders (170). A linear actuator (300) operates a reclining motion. A curved arm for deformation is provided to a mount (320) on which the actuator (300) is mounted, and a slit (145) is provided in a link plate (140) to which a rod is connected, and in a state where a forward force F is applied, the curved arm deforms and absorbs the impact. An impact absorbing structure is also provided to the legs (120).

Abstract: An aircraft passenger seat (100) has a seat bottom frame (150), and the seat bottom frame (150) is supported by an eccentric cam (210). A seat back frame (170) which rotates about a support point (250) is provided with a damper mechanism (300). When the seat back frame (170) is tilted forward from an upright position about the support point (250), a gas damper (310) is compressed and prevents rapid tilting. This energy assists force for returning the seat back to the upright position. The eccentric cam (210) rotates and lowers the seat bottom frame (150) so as to prevent cushions from being collapsed. A lock mechanism (400) highly rigidly retains the seat back frame at a bed mode position.

Abstract: A divider unit (100) for a passenger seat has a slide rail (120) that is fixed onto a side shell (12) surrounding the seat. A plate-like divider (150) is equipped with two linear guides (170) inserted in the slide rail (120) and slides within the slide rail (120). A stopper (130) attached to a front end of the slide rail (120) has, a tapered surface (132), and the divider (150) is stopped when a front end of the divider (150) rides over the tapered surface (132), thereby preventing generation of collision noise.
