Abstract

The utility model discloses a self-tilting seat for automobiles and airplanes, additionally provided with a backrest self-tilting mechanism on the basis of the prior seat. While in use, the backrest of the seat can automatically tilt backward following the back of a person when the person tilts backward, and can automatically restore to the original position following the back of the person when the person sits up. The utility model has convenient operation, comfort, a simple structure, low cost and easy fabrication.

Description

Wantonly self tilting car or aviation seat

The utility model relates to a kind of seat, particularly random self emptying type automobile, aero seat.

Present automobile, it leans against seat on the aircraft some and can tilt, some then can not, the needs that can not the bevelled seat obviously can not satisfy people's journey, the people is sat feel very tired long afterwards, can the bevelled seat its all need operate proprietary mechanism when leaning against, because the using method difference of various leaning devices, the people of first contact does not damage these devices unavoidably, when particularly some seat back is by inclination, need take advantage of a person could realize that with bigger moment this often makes the old,weak,sick and disabled and children feel powerless, with the exception of this, what have seat now leans against leaning device behind repeated use, and very easily malfunctioning, service life is shorter; And the complex structure of these mechanisms own, productive costs and production difficulty are all higher.

The purpose of this utility model is to provide a kind of automobile, aero seat that can arbitrarily incline certainly that lean against easily simple in structure, comfortable, leaning against when the people swings back of this chair can recede automatically with people's back, when the people sits up, lean against and can automatically reply original position with people's back.

For achieving the above object, the solution that the utility model adopts is: by handrail, bogie side frame, side plate, the automobile that mounting and back of the body frame are formed, increasing by one on the aero seat again leans against from inclining mechanism, this mechanism mainly is made up of two slide bars and two guide holders that match with slide bar, two slide bars are separately fixed on mounting the right and left bottom surface, two guide holders are separately fixed on the transverse tube inboard, middle part of left and right side frame, slide bar is bent an angle, one side of its angle is vertical with the mounting of bearing, the mounting of another side and bearing tilts, one hole is arranged on the guide holder, be with the nylon duct ring in the hole, the sloping portion of slide bar can be enclosed within the centre hole of nylon duct ring with slidably reciprocating.

In the above-mentioned solution, the cross section of slide bar is circular, and there is a limiting stopper its terminal corner near slide bar of part that tilts.

In the above-mentioned solution, also be with nylon friction ring and bearing cap shim on the guide holder, the shape and the slide bar surface configuration of the part that contacts with slide bar on the friction ring match.

The utility model has been owing to increased by one and leaned against from the mechanism that inclines on the basis of original seat, thereby of the present utility model leaning against can satisfactory automatic hypsokinesis and reset, and has overcome the defective with front chair, makes the user feel convenient and comfortable.With the exception of this, this mechanism itself is simple in structure, cheap for manufacturing cost, is easy to produce.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is for leaning against the constructional drawing from the mechanism's part of inclining in the utility model.

Fig. 3 is the right elevation of guide holder part among Fig. 2.

Fig. 4 is the section-drawing of Fig. 3.

Fig. 1 is a structural representation of the present utility model, as can be seen from Figure, the utility model is mainly by handrail 1, bogie side frame 2, side plate 3, mounting 4, back of the body frame 5 with lean against from the mechanism 6 that inclines and form, wherein mounting 4 and back of the body frame 5 are lined with a laminate 11 and are surrounded by foam 9 and lining 10, lean against from the mechanism 6 that inclines and be installed in mounting 4 following the right and lefts, its structure such as Fig. 2, Fig. 3, shown in Figure 4, as can be seen from Figure, it comprises slide bar 6a, guide holder 6b, nylon duct ring 6c, friction ring 6d, limiting stopper 6e and bearing cap shim 6f, totally two of slide bar 6a are by 35 ^#Steel is made, its end is fixed on below the mounting 4 by screw 7, the other end directly is inserted in the pole socket 8 that is fixed on the mounting 4, its shape is bent as shown in Figure 2 an angle, one side of angle is vertical with the mounting of bearing 4, the mounting 4 of another side and bearing tilts, the angle that slide bar 6a is bent during concrete use the and the length on angle both sides are decided on leaning against 5 required sweptback angles, totally 2 of guide holder 6b, the slide bar 6a of each guide holder 6b and homonymy matches, its structure as shown in Figure 4, it comprises minor diameter one end and major diameter one end, minor diameter one end directly is inserted in the inboard of the middle part transverse tube 2a of bogie side frame 2, free to rotate behind its insertion transverse tube 2a, one its axis and the perpendicular hole of guide holder 6b axis are arranged on major diameter one end, be with nylon duct ring 6c in the hole, the sloping portion of slide bar 6a is enclosed within the centre hole of nylon duct ring 6c, and can in the hole of 6c, slidably reciprocate, the effect of nylon duct ring 6c is that the slip of slide bar 6a is steady, and its surperficial unlikely scratch after slide bar 6a is slided for a long time, failure-free guarantees in order to make this effect obtain more, on guide holder 6b, also be with a friction ring 6d, the shape of friction ring 6d as shown in Figure 3, on it with the contacted part of slide bar 6a be half arc surface, for making this arc surface and slide bar 6a surface closed contact, be equipped with a bearing cap shim 6f in the left side of friction ring 6d, nylon duct ring 6c and friction ring 6d will produce certain friction when slide bar 6a slides like this, make that the sliding velocity of slide bar 6a is suitable, the people can not produce sense of insecurity when taking layback, being that guide holder 6b was unlikely when slide bar 6a was slided in addition collides with corner slide bar 6a, end at slide bar 6a sloping portion has a limiting stopper 6e near the corner, limiting stopper 6e is cylindric, directly be enclosed within on the slide bar 6a, lean against 5 like this when backing tilt to maximum angle, guide holder 6b only contacts with limiting stopper 6e, thereby has guaranteed the service life of slide bar 6a.The centre hole section form of the cross section of slide bar 6a and nylon duct ring 6c both can be circle and also can be squarely, and the also available material that other has equivalent effect of friction ring 6d and duct ring 6c is made.

The side frames base was fixed on automobile or the aircraft by mounting screw when the utility model used, its working process is such: when the people takes layback, leaning against 5 recedes around its attachment point on bogie side frame 2, simultaneously with lean against 5 mountings that link to each other 4 owing to the slip of slide bar 6a to reach, shown in the long and two-short dash line among Fig. 1, when slide bar 6a slides into limiting stopper 6e and contacts with guide holder 6b, lean against 5 and tilt to maximum angle, the people can swing back and lie down this moment, and when the people sat up, slide bar 6a will be to lower slider, lean against 5 along with people's back homing gradually, whole process is steady, comfortable, need not operate any device, use very convenient.
