Abstract

The utility model belongs to the field of sofa manufacture and in particular relates to a horned zigzag spring assembly for a sofa seat frame. The horned zigzag spring assembly for the sofa seat frame comprises horned zigzag springs; each horned zigzag spring comprises an S-shaped zigzag spring section with the front end connected with a wooden batten in the front of a seat, a vertical section formed by bending the S-shaped zigzag spring section downwards, a hook formed by horizontally bending the vertical section, and a pothook on the hook; each pothook comprises a hooking part connected with the corresponding hook and a beam part fixed on a back seat wooden batten through a spring fastener. According to the technical scheme provided by the utility model, the continuity of elastic force of the spring assembly in the seat frame can be effectively ensured, the height of the back part of the sofa seat can be ensured, and the sitting feel can be ensured and controlled well; since the height of the back part of the seat increases due to the horned zigzag spring, the usage amount of fillers in the back part of the seat can be reduced.

Description

A kind of band for sofa seat frame angle snake spring assembly

Technical field

The utility model belongs to sofa and manufactures field, is specifically related to a kind of band for sofa seat frame angle snake spring assembly.

Background technology

Sofa mainly comprises seat, handrail and backrest, the fabric that wherein seat comprises seat frame, is fixed on spring assembly in seat frame, is arranged on the inserts on spring assembly and is coated with part forms, and wherein the comfort of spring assembly and structure thereof and sofa is closely related.

As shown in Figure 1, prior art medi-spring assembly comprises the spring 101 of a plurality of parallel arrangements, spring 101 1 ends are by the fixing present front Wooden Batten 102 of snak link 104, spring 101 other ends are by the fixing present rear Wooden Batten 103 of snak link 104, between spring 101, by paper bag steel wire in seat 105, reinforce, described spring 101 is generally snake spring or flat spring, it in figure, is the snake spring, the snake spring is the S Linear spring that a plurality of bend unit that join end to end form, radian after snake spring or flat spring are fixing is too low cause after taking excessively flat, subsides power without issue, and the seat sense of sofa seat rear section is partially hard and seat sense control effect is undesirable, the fixing means of snak link 104 causes snake spring length shorter.

The utility model content

Technical problem to be solved in the utility model be current snake spring radian too low, make sofa paste without male offspring power, it is partially hard that sense is sat in the sofa rear section, the fixing means of snak link causes snake spring length shorter, in order to overcome above deficiency, provides a kind of band for sofa seat frame angle snake spring assembly.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: described a kind of band for sofa seat frame angle snake spring assembly comprises band angle snake spring, describedly with angle snake spring, comprise the S type snake spring section that front end is connected with Wooden Batten before seat, by S type snake spring section, bent out downwards vertical section, the crotch folded by vertical section horizontal curved and be arranged on the hook on crotch, described hook comprises the section that links be connected with crotch and is fixed on the crossbeam section on the back seat Wooden Batten by snak link, vertically section has increased the radian of spring assembly, improved subsides power after sofa, increased human comfort, hook connects has increased snake spring length.

Further, the knuckle between described snake spring section and vertical section is 90 °.

Further, the knuckle between described vertical section and crotch is 90 °.

Further, the described width that links section is less than the width of crossbeam section.

Further, described snake spring section arranges the reinforcing of paper bag steel wire with a vertical section joint.

The technical scheme that the utility model provides can effectively guarantee the elastic force continuation of seat frame inner spring assembly, guarantee the height of sofa seat rear section, can be good at guaranteeing and control block sense effect, and band angle snake spring assembly has promoted the rear height of seat, can reduce the use amount of the inserts of a rear section.
