Definitions
- the present invention relates to an aircraft seat, in particular one convertible to a bed.
- Convertible seats are well known. There is, however, a difficulty in arranging a maximum number of such seats in an aircraft cabin, in that they are not readily configured in lines abreast as regards access. A staggered or herringbone arrangement is preferred in terms of privacy and efficient arrangement of the seats in a cabin.
- An awkwardness of a herringbone arrangement of essentially rectangular seats along the edge of a cabin is that at one end - the head end in practice - a triangular area exists against the cabin wall beyond the end of the seat.
- the object of the present invention is to utilise the triangular area by accommodating part of the reclined seat forming the bed surface in the triangle.
- An alternative which we have adopted in the present invention is to lower the head rest into the triangular area. This makes for more efficient use of the space, but creates another problem in that the cabin wall is not vertical but curves inwards over the triangle. Lowering a full length seat backrest and head rest into the triangular space to make most efficient use of the space risks fouling of the top edge of the head rest with the cabin wall.
- an aircraft seat convertible to a bed which comprises:
- a seat having: • a squab and a backrest, both being movable;
- drive means for moving the headrest to foreshorten the combined length of the backrest and the headrest, for movement of the backrest between its dispositions for the sitting configuration and the bed configuration, and to extend the shortened length when the backrest is moved to its disposition for either of these configurations.
- the improvement allows the top of the headrest to be the head end of the bed and adjacent the cabin wall, i.e. in the area referred to above as the triangle, with the cabin wall being in the position of a bed head, albeit at an acute angle to the length of the bed. This is possible despite the cabin wall overhanging the head rest, since as the backrest is lowered, the top of the headrest is moved away from the cabin wall towards the seat squab.
- the drive means may manual, it is preferably power operated.
- the squab movement mechanism can be a linkage mechanism, in which a single actuator moves all parts of the seat in phase with each other between the different configurations of the seat, in the preferred embodiment, the mechanism includes a plurality of actuators under control of a control system programmed to synchronise the actuators.
- the headrest can be arranged to move translationally towards the seat squab general parallel to the backrest to achieve the foreshortening of the backrest and the headrest.
- the headrest is pivotally arranged on the backrest for foreshortening movement by angling of the headrest such that the front faces of the headrest and the backrest form an obtuse angle, the control system being programmed to achieve this obtuse angle during lowering of the backrest from the sitting configuration to bed configuration.
- the headrest is pivotally connected to the backrest at a pivot axis therebetween, close to the front of faces of these.
- the headrest may be connected to the backrest by legs which can be telescopically withdrawn (e.g. into tubes in the frame of the backrest) to bring the headrest closer to the backrest and thereby to foreshorten the combined length of the backrest and the headrest.
- the squab movement mechanism and the control system can be an integrated mechanism with a single actuator lowering both the seat backrest and inclining the headrest forwards during such lowering, with the control system being a simple up/down control.
- separate actuators are provided for the backrest and the headrest, typically electric motor and gearbox driven lead screw devices, and the control system is an electronic controller.
- hydraulic pump and ram devices can be used.
- the backrest actuator (and squab) actuators can be as described in our prior European Patent No 1 ,074,468 ("Our Earlier European Patent").
- the controller is programmed to allow the headrest to be raised for watching of television when the seat is fully reclined to bed configuration and adjusted to a convenient angle if the seat is stopped between sitting and bed configuration, with the proviso that it is not angled back to foul the cabin wall.
- the unit has a shelf surrounding the headrest in its lowered, bed position, with the shelf being at the same general level as the headrest surface, except that the shelf is recessed adjacent the headrest at least around part of the extent of the head-rest/shelf interface.
- an anti-entrapment collapsible device will normally be provided between the headrest and the recessed surface.
- This device can be a bellows device.
- the recessed surface can be open, to provide access to the void therebelow, but this is awkward to reach and is not preferred.
- Figure 1 is a perspective view of a seat unit incorporating convertible bed in accordance with the invention
- Figure 2 is a plan view of the seat unit of Figure 1 ;
- Figure 3 is a side view of the seat in Figure 1 in its normal sitting position;
- Figure 4 is a side view of the seat in a partially reclined position;
- Figure 5 is a side view of the seat in a further reclined position;
- Figure 6 is a side view of the seat in a fully reclined, bed position;
- Figure 7 is a side view of the seat in the bed position with headrest raised;
- Figure 8 is a scrap side view on a 1 arger scale of the head rest in its Figure 7 position.
- Figure 9 is a similar scrap side view of an alternative telescopic headrest.
- the seat unit there shown has a seat 1 divided from adjacent seats (not shown) by partitions 2, there being equal numbers of seats and partitions in a line of seat units, except that end seats will have special partitions. Therefore a line of n seats has n-1 partitions and two special partitions.
- the seat has a movable squab 11, a movable leg rest 12, and a fixed foot rest 14, which also are conventional.
- the movable backrest 15 of the seat is conventional, save that it has a headrest 17 pivotally connected to it about a pivot axis between them and close to the front face of the backrest and the headrest.
- a control panel 21 is provided on the partition 2 for controlling the disposition of the seat.
- the seat is supported on:-
- front legs 26 pivoted to the aircraft deck 27 and the underside of the front of the squab;
- the seat is actuated by a slide actuator 29 acting between the frame 23 and the front legs 26 and recline actuator 30 acting to extend or retract the rear legs.
- a further actuator (not shown) extends or retracts the foot rest.
- the pivoted head rest 17 is provided with a 41 rear crank pivotally connected to a lead screw 43 from an actuator 44 for rotating a non-shown screw nut.
- the arrangement is such that the headrest can be pivoted about an axis 45 to lie at an obtuse angle ⁇ (see Figure 5) with respect to the front face of the backrest or generally parallel therewith.
- the back of the headrest is provided with a collapsible bellows 46 and a movable back plate 47, normally urged away from the headrest by internal pressure or resilience, these components being shown in Figures 7 & 8 only.
- Figure 3 shows the normally sitting up position of the seat, in which the slide actuator 29 holds the squab back towards the cabin wall 48 and the recline actuators 30 are extended.
- Figure 4 shows the seat slightly reclined with the slide actuator 29 unadjusted and the rear legs 28 shortened by the recline actuators. As will be seen in Figure 4, further reclining of the seat, which is for rest only, is possible only with either sliding movement of the squab away from the cabin wall or forwards tilting of the head rest. In practice, both are required.
- a controller incorporated behind the control panel 29 co-ordinates the actuators whereby as the seat is reclined through the position shown in Figure 5, the head rest is kept clear of the cabin wall. The fully reclined position is shown in Figure 6.
- the head rest is lowered into a recess 51 in shelving 52 at the rear of the seat unit along the cabin wall, this shelving - including a trinket tray 53 - is set at the level of the reclined top surface 54 of the headrest and the backrest.
- the recess has a surface 55 just below the level of the back of the headrest, when fully lowered. In this position, the bellows 46 and back plate 47 are compressed between the headrest and the recess surface 55.
- Raising of the seat again is the reverse operation of reclining.
- the seat units are set as close to the cabin walls as possible with the width of the adjacent gangway being maximised. Equally it allows a longer bed for a given extension of the seat from the cabin wall and a given width of gangway.
- FIG 9 the alternative there shown is of a telescopically arranged headrest 117 on a backrest 115 similar the back rest 15.
- the headrest has a pair of legs 151 telescopically received in tubes 152 incorporated in the frame (not shown) of the backrest.
- a motor and reduction gear device 153 is also mounted in the backrest, with a lead screw 154 extending into a nut 155 fast with the bottom of one of the legs 151.
- the arrangement allows the controller to withdraw the head rest towards the backrest in the position equivalent to Figure 5 and enable the backrest to be moved between the sitting and bed configurations without fouling the cabin wall.
- the head rest can be manually operated, particularly in the Figure 9 embodiment by providing a manual lever in place of the motor drive 153.
- the head rest has a rounded top
- this can be modified to allow the very top to pivot forwards to give a more conventional appearance, with the top being folded up for use. This envisaged primarily as a matter of appearance as opposed to function.
