Abstract

The utility model relates to a folding chair for airplanes, in particular to an airplane chair which can be folded for the second time. The folding chair comprises a back, folding legs, a cushion, a primary unfolding shaft and a secondary unfolding shaft, the cushion is foldably mounted on a supporting structure through the primary unfolding shaft, the back is foldably mounted on the cushion through the secondary unfolding shaft, and the outer side of the cushion is provided with the folding legs. The folding chair overcomes the limitation of mounting a chair in a cramped space, the application range of the chair is greatly broadened, and because all the folding parts of the folding chair are provided with locking mechanisms, the chair is firm and reliable, and cannot be easily deformed when in use.

Description

A kind of aircraft folding seat

Technical field

The utility model relates to a kind of aircraft folding seat, especially a kind of seat that can twice-folded.

Background technology

Folding seat mostly is preparations such as bus attendant, observer on the existing aircraft, its folding direction be " hinge " formula, once folding perpendicular in the chair back plane, be difficult to find suitable position that a folding seat is installed for the less aircraft of free space, and a traditional folding seat folding direction is had relatively high expectations to the locus of selected installation bearing surface, sometimes be difficult to choose this chair mounted requirement of suitable both adaptations, can satisfy the dual-purpose position of the visual field direction requirement of passenger again.

Summary of the invention

At existing aircraft, the deficiency that a folding seat can not be installed because the narrow and small and specific line of vision in space requires in some position, the utility model provides a kind of position use narrow and small in the space that both be adapted to, and can satisfy the twice-folded seat of passenger line of vision requirement again.

The technical scheme that the utility model is taked is: a kind of aircraft folding seat, comprise the chair back, collapsible chair leg, chair cushion, axis of dilatation, secondary axis of dilatation, chair cushion is by folding being installed on the supporting construction of axis of dilatation, the chair back is installed on the chair cushion by the secondary axis of dilatation is folding, and the bottom of chair cushion has folding chair leg.

Further, for better implement the utility model, has the rotation locking device between above-mentioned chair cushion and the supporting construction.

Further, for better implement the utility model, has the rotation locking device between the above-mentioned chair back and the chair cushion.

Further, for better implement the utility model, the rotation locking device between the above-mentioned chair back and the chair cushion is static stall and pin.

Further, for better implement the utility model, above-mentioned chair leg has the rotation locking device.

The utility model is taked the twice-folded design, overcome the restriction that seat is installed for small space, strengthened the range of use of seat greatly, the folding place of folding seat all has locking device in addition, makes seat solid and reliable in use not yielding.

The specific embodiment

Describe the utility model in detail below in conjunction with Figure of description, please refer to Figure of description 1～Fig. 4.

A kind of aircraft folding seat, comprise the chair back 1, chair leg 2, chair cushion 3, axis of dilatation 5, secondary axis of dilatation 6, chair cushion 3 is by axis of dilatation 5 folding being installed on the supporting construction 4, the chair back 1 is by secondary axis of dilatation 6 folding being installed on the chair cushion 3, and the bottom of chair cushion 3 has collapsible chair leg 2.Two hinged points of design on aircraft supporting construction 4, support structure point as the fastening aircraft folding seat, be connected on the joint of correspondence position on the chair cushion 3, hinged point and joint form an axis of dilatation 5, chair leg 2 is connected on the chair cushion 3 with the hinge form, can be to launch in the opposite direction with the seat side of opening, and when a seat is opened, chair leg 2 is launched to be fixed on the floor 7, the chair back 1 is connected with the form of chair cushion 3 by hinge, this connection structure forms secondary axis of dilatation 6, it can be put into the certain position finger lock at the chair back 1, forms the twice-folded seat of the deployed condition with solid form.More than hinged point can be the ear form of inserting, also can be bearing type.The collapsible chair leg that install the bottom of chair cushion, can be because of the different designs of different aircaft configuration forms different supporting forms is as designing the strong point on two framing members nearby.

Further, for better implement the utility model, above-mentioned collapsible chair leg has the rotation locking device.

Side direction twice-folded seat can be installed in the plane, the forward sight visual field of passenger, once launch the edge perpendicular to preceding apparent direction, the mounting plane direction that promptly is parallel to a folding seat of tradition, secondary launches to turn down the chair back backward along being parallel to forward sight visual field in-plane, can design gear and gear lock in secondary axis of dilatation mechanism.

During use, at first be that folding seat is put down along an axis of dilatation 5, chair leg 2 expansion this moment, chair cushion 3 puts down fully by the time, and chair leg 2 also launches fully; In use can be as required to fixing between chair leg 2 and the floor 7, as shown in Figure 2;

Secondly, the chair back 1 is launched along secondary axis of dilatation 6, till vertical with chair cushion 3, and lock, as shown in Figure 3, folding seat is in running order with regard to opening fully like this, and Fig. 4 is its secondary expansion side direction view.

Use same quadrat method, can reverse folding seat.

This folding seat is not limited to install aboard, also can be used for being installed on the folding occasion of packing up of needs, and such as automobile, factory building etc., especially all the more so at small space, all this kind all is subjected to protection of the present utility model.
