Abstract: A passenger seat assembly for a vehicle, particularly an aircraft, which is adapted to provide self-contained, individual seating and sleeping accommodation for a passenger, said seating assembly includes a supporting structure (42) for supporting said assembly off the floor of a vehicle; one or more movable, passenger-bearing, structural components (71,72); and means for connecting said movable, structural components to said structure such that said components can be selectively moved between a seat configuration, in which a plurality of passenger-bearing surfaces on said one or more structural, movable components (71,71) or said supporting structure form a seat for the passenger, and a bed configuration, in which a plurality of said bearing surfaces (47,48,67,74,76) are disposed substantially coplanarly and substantially contiguously to form a bed for the passenger; characterized in that at least one of said movable components (72) is double-sided, comprising first and second opposite sides, one of said sid

Abstract: A passenger accommodation cabin for a vehicle, particularly an aircraft includes a wall defining a passenger accommodation area; a plinth disposed substantially at floor level and adapted to support a mattress within the accommodation area to provide at least one substantially flat bed; a false floor that is selectively movable between a deployed position in which the false floor at least partially covers the mattress and a retracted position for allowing use of the bed; and a seating system having at least one seat and associated supporting structure for supporting the seat within the accommodation area generally above the mattress.

Abstract: An airway for insertion into the mouth to provide a passage for air or anaesthetic gas into the trachea. In order to prevent damage to the teeth of the patient which can occur owing to involuntary clamping of the jaw during anaesthesia, the airway is adapted to hold the mouth open to prevent excessive force being exerted between the upper and lower front teeth. In the described embodiment, the airway has bracing portions in the form of two-section tubes (14) adapted to fit between the upper and lower molar teeth on each side of the mouth, the tubes also providing part of the passage for air or gas. The bracing tubes (14) are connected to a third tube (12) which is curved so as to extend into the orapharyngeal space. The airway may be formed in one piece from plastics material, and may be reusable or disposable.

Abstract: A retractible leg rest for an aircraft chair which is stowed beneath the seat when not in use. The leg rest is mounted on a platform attached to an articulated frame mounted beneath the chair. The reticulated frame includes two quadrant plates which are pivoted at their centers about a horizontal bar extended beneath the front of the seat. The platform quadrant plates are connected by linkage arms and link members so that when the platform is drawn outward from beneath the chair, the quadrant members are swung upward by the link members and the linkage arms elevate the rear of the platform along an arcuate path which passes clear of the front of the seat of the chair so that the leg rest is brought into leg-support relationship with the seal of the chair. The angle of the leg rest to the seat is adjustable by means of an array of notches with quadrant members.

Abstract: The invention provides for automatically discharging aerosol cans and further includes the provision for controlling the time at which such discharge takes place.
