Definitions

  • This invention relates to a reclining seat
  • Airline Economy Class Seating is, by definition, less spacious than Business, Club or First Class seating.
  • Minimum seat pitch see Figure 1 MSP
  • the distance between the back of your seat and the back of the seat in front ranges amongst the 29 largest scheduled and charter airlines from 737 mm to 864 mm.
  • Personal passenger space (Figure 1 PPS) is the seat pitch reduced by the thickness of the seat back, often circa 51 mm, and this space is reduced again when the seat in front is reclined for comfort (Figure 1. RPPS).
  • the average seat pitch in business class rose from 36" to 55", while in economy class it fell from 34" to 32".
  • Seats which more fully recline, such as may be found in premium cabins require a greater seat pitch, ie more horizontal space, in order to provide additional rake for the seat back and additional space for a leg-raising support panel to be activated.
  • An object of this invention is to provide a reclining seat in which an internal seat cushion, back cushion and neck cushion assembly is permitted to move relative to an outer rigid seat chassis and relative to an outer back frame provided with limited rake adjustment, in such a way as to move the passenger from an upright sitting position to a reclined position and so that the inner back cushion assembly can recline at a greater angle from the vertical than the limited rake-adjustable outer back frame and the seat cushion assembly can move forward and downward relative to its original upright position, effectively lowering the torso closer to the floor and thereby effectively raising the occupant's legs relative to the floor, so that the seat will fully support the head and neck, the entire spine and the upper legs, alleviating pressure on the buttocks and the base of the spine, substantially reducing pressure points and stress on the lower limbs and feet and reducing the potential of restricted blood flow which may occur when the front edge of the seat presses into the back of the leg and achieving such movement, if used in an aircraft environment, within the seat pitch afforded to conventional fixed seats

  • an adjustable seat comprising a back rest portion coupled at its upper portion to a first guide inclined at a first angle to the horizontal to constrain the back rest portion at the point of coupling, for movement along said first guide, a seat portion pivotally coupled to a lower portion of the back rest portion and coupled to a second guide inclined at a second angle to the horizontal such that as it moves along the second guide the attitude of the seat portion remains substantially constant, the said second angle being smaller than the first angle.
  • the first angle is substantially twice the magnitude of the second angle.
  • the first angle is in the range of from 1.25 to 2.25 of the second angle.
  • the second angle lies preferably in the range of from 30° to 40°.
  • the first guide comprises a dog-legged guide including an upper section inclined at the first angle, and a lower section articulate with the upper section and inclined at a third angle intermediate between the first and second angles.
  • first, second and third angles are preferably between 80° and 90°, 65° and 75°, and 33.5°and 43.5° respectively.
  • a headrest may be provided that is pivotally connected to the backrest portion.
  • the first guide is advantageously a track, and the upper portion of the back rest is coupled to the track by a runner secured to the back rest, and engaging the track.
  • the second guide is advantageously a track and the seat portion has a runner rigid supported thereon and engaging the track.
  • the track may comprise a slot or a rail with a corresponding runner imprisoned therein or thereon.
  • the first and second guides may each comprise a pair of spaced tracks each coupled to a respective back rest portion and seat portion.
  • the seat portion includes at least one triangular support plate having one edge supporting a horizontal part of the seat portion and another edge carrying a pair of spaced runners engaging the track.
  • the back rest portion carries a neck support cushion and a lumbar support cushion.
  • the adjustable seat may include drive means for driving the upper portion along the first guide and/or driving the seat portion along the second guide.
  • the drive means may take the form of a rack and pinion driven by an electric motor. Instead, the drive means may comprise a hydraulic or pneumatic piston and cylinder arrangement.
  • the back rest portion carries a pair of pivotal arm rests.

  • All components should be manufactured from suitable materials that are light but robust, and the chassis and frames may be fitted with fairing panels that enclose as far as possible any moving or exposed parts and protect the occupant from access to any cavities created when the mechanism is activated.
  • Cushion assemblies should be upholstered in appropriate materials, which may be flame retardant. All of the various seat components should be able to withstand appropriate industry stress and performance tests.
  • the seat mechanism should be aligned to permit the functions to be operable, if used within aircraft, within the seat pitch afforded to conventional fixed seats and without impinging to any greater extent than a conventional design upon the personal space of the seats fore and aft of it.

  • the cavity between adjacent seat cushions may be fitted with a pad that will provide a continuous cushion or lower arm rest when the upper arm rest is retracted.
  • the back of the seat may be fitted with a retractable stowable tray and the rear of the head rest may be fitted with a television or plasma screen.
  • the seat frame may be independent, or connected to adjacent seats in such a way as to provide uninterrupted leg room for the passenger behind, in which case offset floor anchors can mount the assembly of seats into floor mounting tracks.
  • the mechanism should permit the passenger's legs and feet to occupy a space under the seat in front that is not normally generally accessible and the slim design of the seat cushion support should create additional vertical space when the seat mechanism in front is also activated.
  • An additional pivoting or massaging foot support may improve comfort and circulation by exercising the calf muscle.
