Description of the Invention: [Technical Field] The present invention is an improved structure of a seeding structure, which is mainly provided with a pair of elastic backings which are provided with wires on both sides of the front side of the seat back plate for interlocking operation. , Jin X can change the curvature of the elastic backing when the wire is stretched and contracted, and the position where the elastic back is arched to the inner side of the seat back can be adjusted, so that the waist of the net person can be adjusted and fitted. The effect of the branch building, and the problem of the squat posture. [Prior Art] Since the structure of the chair has the purpose of conforming to the back of the human body to provide the supporting function, it is extremely important for the structural comfort of the entire chair. / In the conventional chair, the main part is made up of a layer of elastic foam on the back of the chair and then covered by a cloth cover, which is compressed by the elastic foam (4) force _, can be used The sealing material serves the purpose of cushioning and elastic support, but since each user's body shape is not the same, the comfort effect that can be provided is not high. Therefore, in recent years, the elastic backing pad that is made with the guide can be placed between the seat back plate and the elastic (four), which can change the curvature of the elastic foam in the arc of difficulty (four). In response to the user's back, it is better to match the _(four) _ better benefits, but for the user's waist, but it is not able to obtain the suspension of the supporting role (the chair back can be _ should The Ministry of Finance, but can not fit the user's waist), so it is prone to backache after sedentary. In view of the above problems, the inventor deeply understands that although the structural design of the back of the chair can achieve the adjustment function conforming to the curve of the back of the human body, since the waist curve of the human body cannot be supported by the back of the chair, the chair is engaged for many years. With the experience of creation and design, and actively researching and improving, under the careful consideration of various conditions, we finally create the structural composition of this creation, which will completely solve the above-mentioned shortcomings. SUMMARY OF THE INVENTION The present invention is an improved structure of a seat back, which is mainly provided by a flexible backing pad which is provided with wires on both sides of the front side of the seat back plate and is oppositely disposed, and the elastic backing pad can be driven by the extension and contraction operation of the wire. The arc changes to the inside and then moves to the inside. Therefore, after the implementation, the following effects can be achieved: Since the elastic back pads which are provided with the wires on both sides of the front side of the chair back plate of the present invention are relatively arranged, the user is seated in response to the user's seat. When the waist position on both sides is lower, 'when adjusting for different fat body users', the arc of the elastic back pad can be changed under the extension and contraction operation of the wire to be arched inward or outward, so as to cooperate The user's waist size is attached to the support and provides the full support of the user's waist. Therefore, the user's waist will not be suspended and cannot be supported by the seat back, so there will be no sedentary and backache. The problem, and because the elastic backs on both sides are set in the yam state, _ can naturally play the function of guiding the user's sitting position after the user is lying down, preventing Sitting with a person because of askew affect the future development of bones. [Embodiment] In order for the examiner to be able to clearly understand the structural composition of the present invention and the benefits that can be achieved by the present inventors, the rest of the drawings illustrate the examples, and the detailed description is as follows: The elastic backings 2, which are operated by the wires 3 on both sides of the front of the main county backboard, are arranged oppositely (as shown in the figure - 'adhesive/adhesive 5 attached to the front of the shooting plate i and the elastic backing 2 And the cover of the history of the story is a negligible structure, so I won't go into details.) You can use the adjuster 4 to pull the wire 3 to stretch and shrink to drive the miscellaneous back pad. ##合合使用The sides of the waist of the person are given a 'fit to achieve the purpose of assisting the posture of the person to continue to sit. With the composition of the above components, the elastic back pad 2 is an arc-shaped elastic plate (as shown in the second figure), and the two ends thereof are connected by the wires 3, and can be pulled down in the extension of the wire 3 and the length change. The distance between the ends of the (4) 2 is changed (as shown in the third figure), and then the curvature of the elastic backing pad 2 is adjusted to produce a change, so the elastic backing 2 which is disposed opposite to the front side of the shooting plate 塾 is provided. It can be connected to 1373318 via elastic foam. • Touch the sides of the user's waist. When adjusting, the wires 3 on both sides of the elastic back pad 2 can be adjusted synchronously through the adjuster 4 to make the elastic back pad. The curvature of 2 changes to the inner side or expands outward (as shown in the fourth figure), thereby changing the arc state of the elastic foam 5, so that the state of the elastic backing pad 2 can be adjusted to respond to the user's The width of the waist, which makes the elastic backing 2 can push the elastic foam 5 to deform and cooperate with the _ part, the (10), and the squat, providing the purpose of fully supporting the user's waist, so the user's waist will not And the back of the chair is vacant The phenomenon that can't be supported, so there is no problem of sedentary and causing backache. Furthermore, since the elastic back pads 2 on both sides of the seat back 10 are disposed in a relative state, the function of guiding the user's sitting posture can naturally be exerted after the wearer is lying down, thereby preventing the leader from being placed in a skewed posture. Affect the development of bones in the future. # Further, the seat back 1〇 structure of the present invention can be provided with an elastic backing 6 in an in-line state in the middle of the elastic backing 2 on both sides (as shown in the fifth figure).提供 Provides an adjustable pivotal effect on the waist and back of the user, respectively, to provide a more comfortable shot. In the above description, 'the elastic back pad 2 and the wire 3 on both sides and the middle can be more easily operated, and the adjuster 4 of the control wire 3 can be a conventional two-in-one structure, that is, the adjustment button The 4" mandrel 42 is optionally slidably embedded in the two worms 43, 44 - with 8 1373318 moving the side of the toothed reel 4 5, 4 6 (as shown in Figure 6), where the two sides The other end of the wire 3 of the elastic back pad 2 is combined with the same toothed reel 45 to be wound, and the wire of the intermediate elastic back pad 6 is coupled to the other toothed reel 46. When the reel 45 is driven by the adjusting button 41, the elastic back pads 2 on both sides can be synchronously adjusted, and the mandrel 42 of the adjusting button 41 slides into the other screw 44 to form an engagement to drive the toothed reel 4 6 . At this time, the intermediate elastic back pad 6 can be driven to produce a change in curvature (as shown in the seventh figure).
