Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, a kind of folding seat of adjustable backrest angle, this folding seat comprises: backrest frames 1, seat cushion framework 2, a pair riveted joint bearing pin 3, back cushion 4 and seat cushion 5.Backrest frames 1 links together with seat cushion framework 2 is rotatable by a pair riveted joint bearing pin 3.It is outside that back cushion 4 parcel is arranged on backrest frames 1; It is outside that seat cushion 5 parcel is arranged on seat cushion framework 2.
This folding seat also comprises: the first Folding structure be connected with side, backrest frames 1 bottom, with backrest frames 1 bottom opposite side be provided with amount to limiting component 12 a pair first, the seat cushion framework 2 of the one end be connected with backrest frames 1 is provided with the second Folding structure.
As shown in Figure 3, the first Folding structure two ends are provided with a pair first spheres and amount to parts 111.Each first sphere amounts to parts 111 in eighth ball shape.One end that each first sphere amounts to parts 111 is connected with backrest frames 1, and the other end that this first sphere amounts to parts 111 is arranged in seat cushion framework 2.
In the present invention, amount on parts 111 end face at each first sphere and be provided with a first bearing pin mounting hole, a pair first bearing pin position of mounting hole one_to_one corresponding of formation.
As shown in Figure 1-Figure 3, each second Folding structure two ends are provided with a pair second spheres and amount to parts 211, and each second sphere amounts to parts 211 in eighth ball shape.
As shown in Fig. 2-1, each second sphere is amounted to parts 211 and is had double-decker.Be provided with gap between the double-decker that each second sphere amounts to parts 211, this second sphere is amounted to parts 211 one end and is provided with and opens limiting component 2112, and this second sphere is amounted to parts 211 other end and is provided with opening.
Second sphere is amounted to parts 211 and is provided with the one end of opening limiting component 2112 and is connected with seat cushion framework 2, and each first sphere of the first Folding structure is amounted to parts 111 coupling and is arranged on second Folding structure second sphere corresponding with it and amounts in the double-deck gap of parts 211.
In the present invention, amount on parts 211 end face at each second sphere and be provided with a second bearing pin mounting hole, a pair second bearing pin position of mounting hole one_to_one corresponding of formation.And make a pair first bearing pin mounting holes and a pair second bearing pin mounting hole 211 position one_to_one corresponding.
First Folding structure of correspondence is flexibly connected with the second Folding structure by the first bearing pin mounting hole, a second bearing pin mounting hole by each riveted joint bearing pin 3.
As shown in figure 3-1, the second Folding structure is also provided with a pair second and amounts to limiting component 22; Each second amounts to limiting component 22 is arranged on second sphere corresponding with it and amounts on parts 211.Amount to limiting component 12 correspondence for a pair first to be arranged on bottom backrest frames 1 dual-side.
When folding seat is in folded state, amounts to limiting component 12 for a pair first and with corresponding this, the second spacing parts 22 of amounting to are contacted completely respectively, restriction backrest frames 1 folding further.
In the present invention, backrest frames 1, first Folding structure, seat cushion framework 2 and the second Folding structure are all adopted made of plastic, effectively can alleviate seat-weight.
The folding seat of a kind of adjustable backrest angle provided by the invention, specific works principle is as follows:
