Abstract
The utility model discloses a back frame structure of a seat. The back frame structure of the seat comprises a back bent tube (1), back coiled springs (5), back nailing wires (7), and headrest guide tubes (9). Side plate support wires (2) and small lateral back-connecting plates (3) are arranged on left and right sides of the back bent tube (1) respectively. A back wire (4) is disposed at the bottom of the back bent tube (1). Back support wires (6) and wires (8) are arranged on the back bent tube (1) in crisscross form. The wires (8) are straight. An original bottom support plate is omitted from the back frame structure of the seat, a combination of the side plate support wires and the small lateral back-connecting plates replaces an original lateral connecting plate for an angle regulator, the bend of the upper support wire of the back is modified into straight shape, and accordingly manufacturing cost is reduced effectively, mould and tooling costs are reduced, frame weight is reduced, and the seat is lightened.
Description
Technical field
The utility model relates to a kind of seat back-rest framework structure.
Background technology
Original existing backrest frames structure structure shown in Figure of description 1, connected seven parts such as side plate, bottom support plate, backrest S-shaped spring, backrest nailing steel wire, backrest upper support steel wire and headrest conduit by backrest bend pipe, recliner and hang the assembly structure that forms by welding and drawing, play the effect of supporting backrest and connection cushion.Yet there is following shortcoming in existing backrest frames in production and use procedure: owing to use large-area punching press sheet metal component, so that backrest frames weight is higher, be unfavorable for the operation assembling of field worker 1.; 2. use large tracts of land punching press sheet metal component to cause manufacturing cost too high, increase production cost; 3. mould and frock cost are high.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of seat back-rest framework structure for problems of the prior art, its objective is by improving the structure of backrest frames, alleviates the weight of seat back-rest framework, realizes the lightweight of seat.
The technical solution of the utility model is that this kind seat back-rest framework structure comprises backrest bend pipe, backrest S-shaped spring, backrest nailing steel wire and headrest conduit, the right and left of described backrest bend pipe is respectively equipped with the side plate supporting steel wire and is connected little side plate with backrest, the bottom of described backrest bend pipe is provided with the backrest steel wire, also is provided with in length and breadth back rest supports steel wire and the steel wire of cross-distribution on the described backrest bend pipe.
Described steel wire be shaped as straight steel wire.
Has this kind seat back-rest framework structure of said structure by having cancelled original bottom support plate, and the sub-assembly that utilizes the side plate supporting steel wire to be connected little side plate with backrest has replaced original recliner connection side plate, and changed the bending part of backrest upper support steel wire into straight steel wire, effectively saved manufacturing cost, mould and frock cost have alleviated the lightweight that skeleton weight has realized seat.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of prior art.
Fig. 2 is the utility model lateral cross section structural representation.
In Fig. 1-2,1: the backrest bend pipe; 2: the side plate supporting steel wire; 3: backrest connects little side plate; 4: the backrest steel wire; 5: the backrest S-shaped spring; 6: the back rest supports steel wire; 7: backrest nailing steel wire; 8: steel wire; 9: the headrest conduit.
The specific embodiment
Figure 1 shows that the structural representation of prior art, connected seven parts such as side plate, bottom support plate, backrest S-shaped spring, backrest nailing steel wire, backrest upper support steel wire and headrest conduit by backrest bend pipe, recliner and hang the assembly structure that forms by welding and drawing, play the effect of supporting backrest and connection cushion.Yet, owing to use large-area punching press sheet metal component, so that backrest frames weight is higher, be unfavorable for the operation assembling of field worker; Increase simultaneously production cost and mould and frock high cost.
Fig. 2 is structural representation of the present utility model, this kind seat back-rest framework structure comprises backrest bend pipe 1, backrest S-shaped spring 5, backrest nailing steel wire 7 and headrest conduit 9, the right and left of backrest bend pipe 1 is respectively equipped with side plate supporting steel wire 2 and is connected little side plate 3 with backrest, the bottom of backrest bend pipe 1 is provided with backrest steel wire 4, also be provided with in length and breadth back rest supports steel wire 6 and the steel wire 8 of cross-distribution on the backrest bend pipe 1, steel wire 8 be shaped as straight steel wire.Effectively saved manufacturing cost, mould and frock cost have alleviated the lightweight that skeleton weight has realized seat.
