  • Patent number: 9849989
    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.

  • Patent number: 9731830
    Abstract: Provided is an improved reclining mechanism for an aircraft passenger seat. An aircraft passenger seat (100) is provided with a seat bottom frame (152) which constitutes a seat surface, and a seat back frame (162) which constitutes a back rest, wherein cam followers (240, 242) provided on both sides of the seat back frame (162) slide within cam grooves (132) on spreaders (130) supporting both sides of a seat mechanism. When an actuator (200) expands and pivots a link arm (230) in the direction of an arrow R1 to cause the seat back frame (162) to start reclining, a link plate (270) extends in the direction of an arrow F1, and pivots a head rest frame (172) in the ? direction. This operation prevents the line of sight of the passenger from being deviated from a video device provided on a back of a front seat.

  • Patent number: 9567085
    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.

  • Patent number: 7251952
    Abstract: The invention provides an improved air chiller unit mounted on an aircraft for sending cooled air to service carts for serving meals. An air chiller unit is equipped with a refrigeration cycle unit disposed on a casing. The refrigeration cycle unit is equipped with a compressor, a condenser, an evaporator and so on for a refrigerant, and the cooled air is sent via a blower device 60 to a galley etc. A housing 630 of the blower device 60 has an inlet and two outlets 650, 652 for cooled air. A duct member is inserted to one of the two outlets 650 and 652, and the other outlet is sealed. The casing 10 is formed of a honeycomb panel. Since the honeycomb panel has high flexural rigidity, the base plate can support the refrigeration cycle unit by itself. Further, since the panel has superior heat insulating property, the air cooling efficiency can be improved.
