Abstract

An aeroplane seat 1 is provided with a rocking facility (6,10; 8,12) whereby the position of the seat from the upright position is changed by pivoting the whole of the seat about a virtual axis (14), the seat support portion (4) and the seatback (2) remaining in a prescribed relationship one to the other and a pivotable armrest 20 which is foldable into an unobtrusive position in the seatback. The armrest is formed in two pivoted parts, locked in one position when acting as a support and mated one in the other when folded for parking.

Description

IMPROVEMENTS IN OR RELATING TO
AEROPLANE SEATS
This invention concerns improvements in or relating to aeroplane seats.
In particular, but not exclusively, the invention has reference to such seats as are deployed in the economy class areas of conventional l0 passenger-carrying aircraft.
A known attribute of current aircraft seating is inherent and acute discomfort which is characterized by the pitch of the seating, the usually well-worn upholstery, the disposition of the armrests and the difficulty of 15 moving from a trapped non-aisle seat, e.g. a window seat, to the aisle and back. Furthermore, the seat geometry can only be changed by movement of the seatback with little accompanying improvement in the position and posture of the passenger.
20 An object of the present invention is to provide an improved aeroplane seat which at least addresses the problems outlined above and provides for an enhanced level of passenger comfort.
According to the invention an aeroplane seat is provided with a rocking 25 facility whereby the position of the seat from the upright position is changed by pivoting the whole of the seat about a virtual axis, the seat support portion and the seatback remaining in a prescribed relationship one to the other, and an armrest, the armrest being in two parts, one part being pivoted to the seatback and lockable in an open operative position, 30 the two parts being pivoted one to the other whereby
in the open operative position the parts are locked to provide support, and in the closed parked position the two parts pivot to fold closed one mating with the other.
The seat is provided with appropriate extensions which may be in the form of lugs and which are adapted to locate in or on arcuate guides at either side of the seat for the seatback and the seat support portion.
10 The prescribed relationship between the seatback and the seat support portion may be variable and may be varied by the passenger according to requirements. A recessed region between the seats at the level of the armrests is 15 provided whereby the armrests are not intrusive into the seat back area.
By way of example one embodiment of each of the aspects of aeroplane seat according to the invention is described below with reference to the accompanying drawings in which: 20 Figure 1 is a perspective view of a seat in the reclined position; Figure 2 is a perspective view of the seat of Figure 1 in an upright position; Figure 3 is perspective view of an armrest in a partially closing position; and 25 Figure 4 is a perspective view of the armrest of Figure 3 in a closed position adjacent the seatbacks of adjacent seats; Referring first to Figures 1 and 2 of the drawings, an aeroplane seat is shown at 1 and includes a seatback 2 in fixed relationship with a seat 30 support portion 4. The seatback 2 and the portion 4 each have a lug 6,
8 extending outwardly therefrom on each side thereof, and each lug 6, 8 engages an arcuate guide 10, 12 respectively.
The interrelationship as between the lugs 6, 8 and the guides 10. 12 is 5 such as to give the seat 1 a virtual axis 14 of rotation about which the seat 1 is adapted to move as and when desired, the seat being lockable in any desired position at and between fully reclining and fully upright.
The advantage of the seat according to the invention is that of enhanced 10 comfort whereby the seat essentially rocks into the desired position.
Referring now to Figures 3 and 4, the armrest 20 comprises two parts 22, 24, the part 22 being hollow to accommodate the other part 24 in the closed, parked, position (Figure 4). The part 24 is pivoted to the side of 15 the seat 1 and the part 22 is in turn pivoted to the part 24 as shown, the parts being lockable in the open position to provide the requisite support for an arm. The adjacent seatbscks 2 are recessed as at 26 to accommodate the closed armrest 20 as shown in Figure 4. The arrow A'/'B' indicate the manner of closure from the open position, the parts 20 essentially folding one into the other as in the manner of a penknife.
The improved armrest is not intrusive into the seating area or into the seatback per se.

Claims (4)

CLAIMS:
1. An aeroplane seat includes a rocking facility whereby the position of the seat from the upright position is changed by pivoting the whole of 5 the seat about a virtual axis, the seat support portion and the seatback remaining in a prescribed relationship one to the other, and an armrest, the armrest being in two parts, one part being pivoted to the seatback and lockable in an open operative position, the two parts being pivoted one to the other whereby in the open operative position 10 the parts are locked to provide support, and in the closed parked position the two parts pivot to fold closed one mating with the other..
2. A seat according to Claim 1 in which the seat is provided with
extensions adapted to locate in or on arcuate guides at either side of 15 the seat for the seatback and the seat support portion.
3. An aeroplane seat according to Claim 1 or 2 in which a recessed region is provided to accommodate the armrest in the closed parked position.
4. An aeroplane seat substantially as hereinbefore described with reference to the accompanying drawings.
