Abstract

A seat for an aircraft has an open outer shell which embraces a seat portion, a seat back, a head rest and a foot rest when the seat is in an upright position. Also embraced by the shell are a pair of arm rests. The seat is reclinable into a bed configuration such that the seat portion is moved forwardly out of the open end of the shell. Simultaneously, the arm rests are movable between the raised position and the position substantially flush with the seat portion. In the bed configuration, the removal of the arm rests from the raised position significantly increases the width of the bed, thus enhancing the comfort of the user.

Description

Improved vehicle seat

The present invention relates to improved vehicle seat, the present invention is particularly useful for the seat of aircraft.

Generally in order to make seat keep leaning to, typical aircraft seat comprises that one sits body, a backrest, a leg by reaching pair of armrests.The backrest of stand can and tap into leaning between the position of level in the upright position and move.Leg leans against one against the anterior lower position of regaining of seat with the seat is formed between the raised position of effective elongation move.

Have its profile of more exquisite aircraft seat roughly to be bed, this is particularly useful for long-range aircraft, long-haul aircraft.Usually in the first that maximum seat is provided for every passenger, such setting is arranged.Although for each seat provides maximum space, space and weight still are restricted in first, must consider the design and the layout at seat in the main cabin.

Lean to position and leg when rising when backrest is in, the passenger on the seat can be to lean to that posture is had a rest and sleeping comfily.Although the first class seat is wideer than the seat of economy and business class, it can only be limited to bed.Constitute the handrail that chair component is housed in its of a part as seat and occupy certain width.It is generally acknowledged that handrail has the flap table of depositing and advantages such as seat and amusement control appliance.Yet, if there are other purposes will widen handrail, like this, for keeping the constant width that will reduce to sit body of overall width.

The object of the present invention is to provide a kind of seat unit that is more suitable for falling asleep than existing Recumbent seat.

On the one hand, the invention provides a kind of aircraft seat, it comprises that one sits body, at least one side arm and one and this side arm or the adjacent side part of each side arm, at least one side arm stretches out between a state and the retracted mode one and moves, when stretching out state, the upper surface of side arm is arranged to a handrail of seat, and side arm can make the seat broaden when being regained by the state that stretches out.

On the other hand, the invention provides a kind of aircraft passenger compartment seat, it comprises that one sits body, one by body and at least one side arm, by body at vertical position with lean between the position movable, sit body and can move forward to hold to make it to be in by body and lean to the position, described at least one side arm can move forward with sitting body.

The aircraft passenger seat that can lean to be the action that makes space of planes behind the chair back shift-in passenger on the other hand.Seat has constituted a zone by the chair back face of front seat to the chair back of this seat.When the chair back of passenger front seat by forward direction retread by the time, the passenger can feel that this field is occupied, even also can feel under the weather in looser first class.The passenger has paid extra-pay in order to obtain first-class tour condition, and its field is occupied less.

For this reason, suggestion constitutes the field that the passenger has by the stationary housing of a seat of portion's adjustment within it.The passenger can adjust seat in this housing institute limit scope, and does not need passenger's behind that any adjustment is arranged.Seat has a fixed space that is formed by housing, whenever, passenger's action can not change it.But the structure of the seat in the stationary housing may compare exquisiteness, complexity and price comparison costliness, owing to need extra covering also may increase its weight.Guaranteeing that housing is not that stationary housing also should be taken into account the multifunctionality that seat is adjusted under the excessive situation.

The present invention also aims to, the multi-functional adjustment of seat is provided and does not take the space that offers the passenger.

According to a further aspect in the invention, the interior row seat in the aircraft comprises the multiple row seat that is the converged state layout.

In addition, up to the present, in the servicing unit, as televimonitor, desktop, storage chamber etc., all adopt roughly the same scheme, for example, televimonitor or desktop are stored in the seat, then need a series of operation for placing it in the use location, therefore usually are not easy to use.Since the space need also it can be positioned on the side of seat for reduce the width of seat as far as possible.

The present invention also provides a kind of aircraft passenger seat, comprises the support before a seat and is positioned at seat, and described support comprises the servicing unit that uses for passenger on the chair.

Another purpose of the present invention is, servicing unit and setting easily in the aircraft seat useful space are provided.

Therefore, one storable desk also is provided according to the present invention, the wallboard that comprises a table support, the desk upper end is articulated on the wallboard, can between use location and the storage location in the wallboard groove, rotate around pivot, recess is arranged in the wallboard, and the desk upper end is inserted recess and is kept level, makes desk be in the use location.

Constitute problem of tilting seat existence of the shape of bed, promptly produce significantly fluctuating by being in different azimuth by body, seat body and leg.Common bed is flat, and the cushioning effect of bed course has adapted to the bodily form variation of human body like this.Tilting aircraft seat is different with common bed, and the structure of seat is wanted more complicated, and it should make seat-assembly be suitable for lying low.Complex structure will produce take up space and strengthen and the shortcoming of weight increase.

Have crest and trough if the fluctuating of seat regarded as, the aitch bone that leans to the passenger then leans against on the crest that the leg of seat end leans on, this be should by the bed course buffering of seat but incompressible end that bed course does not cushion again.Similarly, the waist of human buttock top falls in, and waist can lean against the trough of the chair back and seat body junction, if the passenger towards the overlong time of simultaneously lying on one's side, will feel the backbone ache.

More complicated is, seat must be able to place the crossover position between the state of complete erectility and bed.For this reason, the shape of the body-accommodating of posture rather than back floating position should be able to is arranged to and lean to seat-assembly.

Therefore, an object of the present invention is to provide a kind of seat, it can change over the shape of bed, and can make the people who leans to feel comfortable.

The present invention also provides a kind of aircraft seat, comprise that one sits body and by body, by body relative to sitting body at erectility with lean between the state and move, sit body and move forward the body that leans on that leans to hold, described seat further comprises first assembly that is installed in seat body front portion, can compensate the fluctuating of seat when leaning on body tilting by the support of adjusting this assembly.

The auxiliary equipment relevant with aircraft seat generally includes a desk, and this desk is collapsible when not using.Folding table generally leaves in the zone of seat, but recognizes now, desk is not deposited as the component parts of seat can make armchair structure that greater flexibility is arranged.

Therefore, the present invention also aims to provide a kind of desk of depositing that is used for the aircraft freight space, the placement of this desk can not influence the structure of seat.

Although be sitting in aircraft first sensation than much loose in business class or economy class, embarking on journey is provided with seat and also is unfavorable for not disturbing mutually between the passenger.Small baffle can be installed between the seat, and dividing plate can arbitrarily be risen or fall to arbitrary passenger.But the action of rising dividing plate can be seen as unhandsome behavior, makes some represent silence to using dividing plate.Be preferably in when placing seat the hidden of necessity can be provided, also needing simultaneously can be by the concealed device of passenger's setting.

Further aim of the present invention is to provide a kind of seat aligning method, to obtain arranging hidden greatly than the seat that generally adopts in the cabin.

Use existing support when support, recovery, installation and mobile seat unit, all trouble can be arranged.For the landing time that guarantees aircraft the least possible, require to finish as early as possible these operating procedures.For ease of fixing the assembly that each seat unit particularly installs the back fast, be preferably in a support behind and the interval of one 3 inches (7.5 centimetres) arranged between the fore-stock of its back device, this makes bolt or other securing members be easy to contact, and provides the operating space for instrument.The body that leans on of the inherent seat of known package unit is equipped with fixing housing afterwards, and the problem of this structure is that when particularly surpassing the seat unit of some, the utilized space in it reduces.

The present invention also aims to provide aircraft seat fast a kind of and that move or safeguard easily.

The invention provides a kind of aircraft seat, comprise one sit body, one can upright and lean to move between the state place the housing that leans against by body and by the body back, the lower position of housing can move backward to hold the body that leans on of the state of leaning at least.

Therefore, when stand up position, kept certain activity space leaning against the housing back, still, when seat moves to when leaning to the position, this space is filled, and the result is easy to that seat rear is fixed and the cabin space that can not reduce to hold the passenger.
