Fig. 1 is the overall structure diagram of the present invention；

Fig. 2 is the structural schematic diagram of the flower-shaped tubing of the sun.

Specific implementation mode

To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing Step ground detailed description.

Overall structure diagram of the invention shown in referring to Fig.1.

A kind of profile structure aircarrier aircraft passenger seat of the embodiment of the present invention, chair framework both sides include intermediate oblique Upper tripod structure and intermediate cant beam 1, base cross members 4 and the composition of back leg 5 that beam 1, upper beam 2 and preceding chair leg 3 form Lower foot rest structure, be connected as one respectively by front beam 6, rear cross beam 7 between the both sides of chair framework.

Form tripod structure, the intermediate cant beam 1 of lower tripod, upper beam 2, preceding chair leg 3, base cross members 4, back leg 5 And pass through front-axle beam multiple way union 8, back rest multiple way union 9, front foot multiple way union between front beam 6, rear cross beam 7 respectively 10, the connection of rear foot multiple way union 11 is integral, as shown in Figure 1.

Front-axle beam multiple way union 8, back rest multiple way union 9, front foot multiple way union 10, rear foot multiple way union 11 are distinguished Each component is fixed by connecting bolt.

Connecting has handrail connecting plate 12 on the back rest multiple way union 9 of rear cross beam 7, setting is rotated on handrail connecting plate 12 There is handrail 13.

Handrail 13 uses proximate matter integral structure, i.e., entire handrail to be made of one piece of plate muscle part, substantially reduces part Number so that the assembly simpler convenience of seat.

It is rotatably connected on handrail 13 and helps arm 14, arm 14 is helped to be rotatablely arranged at handrail connecting plate by connecting axis pin 15 On 12.

Chair framework rotation is provided with backrest 15, and action barrel 16 is provided between 15 handrail connecting plate 12 of backrest, by dynamic Make cylinder itself Telescopic and realizes back tilting angular adjustment.Preferably, action barrel 16 is hydraulic cylinder, and action barrel is by internal Hydraulic pressure is scalable by control button, is rotated around the axis pin at action barrel both ends when stretching, and realizes that backrest inclination angle is adjusted.

The rear foot multiple way union 11 of chair framework rear lower by 17 attachment screw 11a of link block be fixed on guide rail it On, the front foot multiple way union 10 of front lower portion is fixed on by screw 10a on guide rail.

Change seat layout when, chair leg can be made to be slided in track, tripod structure can securing device passenger does not carry For more leg movements spaces.

12 top of handrail connecting plate is rotatably connected to folding dining table plate 18, even if the used time extensible drives to front, when not used Dining table conjunction can be packed up to return on the chair back.

It is additionally provided with the luggage shelves item 19 of U-shaped below chair framework, luggage position is limited by ground, both sides chair leg, is prevented The random mobile ad-hoc of luggage is to move forward.

It is respectively arranged with cushion cloth casing on front-axle beam multiple way union 8, back rest multiple way union 9 before and after chair framework 20, cushion cloth 21 is supported by between cushion cloth casing, and the back of the body is respectively arranged on front-axle beam multiple way union 8, back rest multiple way union 9 To curved support seat.

With reference to structural schematic diagram shown in Fig. 2.

Tripod structure, lower foot rest structure, front beam, rear cross beam are that the flower-shaped tubing of the sun is constituted by section, the pipe Material has inside and outside concentric drums 22, is constituted with the reinforcing rib 23 that several radial radiation shapes are distributed between inside and outside concentric drums 22 The characteristics of sector structure has bending resistance, resistance to compression, torsional strength high, rice heavy and light.

In the present embodiment, the seat cushion back cushion of seat is respectively in accordance with the head of people, and back, buttocks line design is at different Three-dimensional structure is to better adapt to the curve of people, and if backrest is set as rear female, and neck is equipped with front projecting type cushion.

In the present embodiment, all metal materials of seat use aluminum alloy materials, due to the atomic number of aluminium element Smaller, alloy material lighter weight fully mitigates aircraft own wt, reduces the load-bearing pressure of aircraft.

It is above disclosed to be only a preferred embodiment of the present invention, the power of the present invention cannot be limited with this certainly Sharp range, therefore equivalent changes made in accordance with the claims of the present invention, are still within the scope of the present invention.
