Description
Technical field
The utility model relates to a kind of automotive seat, particularly the mounting structure of backrest grid and backrest side board.
Background technology
As shown in Figure 1, car seat back frame 1 comprises both sides side plate 1a, and both sides side plate 1a is symmetrical set, and is provided with backrest grid 2 in backrest frames 1, backrest grid 2 be each side provided with two cylindrically coiled springs 4, the two ends of cylindrically coiled spring 4 are provided with hook.Both sides side plate 1a is provided with equal with cylindrically coiled spring 4 quantity, that position is corresponding grid hanging point 5, this grid hanging point 5 is shaping with side board 1a integrated punching.Wherein one end of cylindrically coiled spring 4 is hooked on backrest grid 2, and the other end is hooked on grid hanging point 5, thus achieves the installation of backrest grid 2 and backrest frames 1.
The subject matter that this structure exists is: direct punching grid hanging point 5 on side board 1a, adds the complexity of side board diel; In use, cylindrically coiled spring 4 and grid hanging point 5 are metal piece, easily produce abnormal sound in friction process, the traveling comfort that impact is driven; Each attachment point of backrest grid 2 will arrange a cylindrically coiled spring 4, adds the complexity of installation, number of parts and product weight.
Utility model content
The utility model aims to provide the hanging structure of a kind of back of seat grid and backrest side board, simplified structure, expendable weight, reduces number of parts simultaneously, improves the comfort feature of installation, reduces manufacturing cost, improves the traveling comfort driven.
For this reason, the technical scheme that the utility model adopts is: the hanging structure of a kind of back of seat grid and backrest side board, comprise backrest frames (1) and backrest grid (2), described backrest frames (1) comprises the symmetrically arranged side board in the left and right sides (1a), it is characterized in that: each side board (1a) is provided with about at least two spaced apart plastic grid suspension members (3), described plastic grid suspension member (3) is made up of " U " shape link (3a) and the semicircle anti-drop block (3b) that is arranged on " U " shape link (3a) two ends, described side board (1a) is provided with grid suspension member mounting hole, when two semicircle anti-drop blocks (3b) are closed up, just in time synthesize a nahlock mated with grid suspension member mounting hole, after described nahlock passes grid suspension member mounting hole from the inner side of side board (1a), hang on the outer wall of side board (1a) by two semicircle anti-drop blocks (3b) separately again, described backrest grid (2) is provided with equal with plastic grid suspension member (3) quantity, the hook (2a) that position is corresponding, and hung on corresponding " U " shape link (3a) by hook (2a).
Preferred as such scheme, described backrest grid (2) is bilateral symmetry, and plastic grid suspension member (3) quantity on two side boards (1a) is equal, position is corresponding.
Further, the width of described " U " shape link (3a) is increased to open end gradually by bottom.Increase the elasticity of plastic grid suspension member, more laborsaving when making installation, install after more difficult drop-off.
The beneficial effects of the utility model: arrange separately the hanging point of plastic grid suspension member as backrest grid, avoid punching hanging point on side board, thus decrease the complexity of diel; Plastic grid suspension member is connected with the backrest Net hanging hook of metal, and friction can not produce abnormal sound; On backrest grid, directly arrange hook be connected with plastic grid suspension member, eliminate cylindrically coiled spring, decrease number of parts, alleviate product weight, reduce manufacturing cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation before improving.
Fig. 2 is the structural representation after improving.
Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 2, the hanging structure of a kind of back of seat grid and backrest side board, forms primarily of backrest frames 1, backrest grid 2 and at least four plastic grid suspension members 3.
Backrest frames 1 is the closed frame structure surrounded by pipe frame 1b on both sides side plate 1a, backrest and backrest foam lower support cylinder 1c, and overall symmetrical.Side board 1a is shaping by steel plate punched, and on backrest, pipe frame 1b is formed by steel pipe bending, and on backrest, pipe frame 1b is downward opening " U " shape pipe, and backrest foam lower support cylinder 1c is formed by steel plate bending, is the semicircular cylinder of upper end open.Two recliner 2 are arranged on the bottom of both sides side plate 1a respectively, and be connected by recliner trace (invisible in figure), recliner trace covers by backrest foam lower support cylinder 1c from bottom to top, when by External Force Acting, first contact with backrest foam lower support cylinder 1c, thus achieve the available protecting to recliner trace; And make the backrest foam bottom of support also rounder and more smooth.The structure of backrest frames 1 is not limited thereto, as long as with the closed frame structure of both sides side plate 1a.
Each side board 1a is provided with about at least two spaced apart plastic grid suspension members 3.Plastic grid suspension member 3 is made up of " U " shape link 3a and two semicircle anti-drop block 3b.Two terminations of " U " shape link 3a respectively arrange a semicircle anti-drop block 3b.Side board 1a is provided with grid suspension member mounting hole, when two semicircle anti-drop block 3b close up, just in time synthesize a nahlock mated with grid suspension member mounting hole, after nahlock passes grid suspension member mounting hole from the inner side of side board 1a, reach the outside of side board 1a, then hung on the outer wall of side board 1a by two semicircle anti-drop block 3b separately.Backrest grid 2 is provided with equal with plastic grid suspension member 3 quantity, that position is corresponding hook 2a, and is hung on corresponding " U " shape link 3a by hook 2a.
Preferably, backrest grid 2 is bilateral symmetry, and plastic grid suspension member 3 quantity on two side board 1a is equal, position is corresponding.In addition, the width of " U " shape link 3a is increased to open end gradually by bottom.
