Description of the invention: [Technical field of invention] The present invention is a cushion structure improvement of a chair, mainly in a seat back plate and a seat cushion plate. Elastic pads with wires on each side are operated. With the characteristics that the curvature of the elastic pad can be changed by the wire, it can be adjusted at any time according to the body shape of different users, so that the back of the chair can support and fit the waist of the user. On both sides, the seat cushion can be used for the contact of the thighs to achieve the purpose of correcting the sitting posture and improving comfort. [Prior Art] The cushion structure of the chair is mainly provided with a seat back and a seat cushion, and its function is to provide a swing, a support and a cushion for the weight of the human body, thereby improving the comfort of the chair. In the conventional cushion structure, the main layer is composed of a layer of elastic foam on the seat back board and the seat back board, and is covered by a cloth cover, and the fork pressure deformation and elastic force of the elastic foaming cotton are used. The function can be used for cushioning and elastic support when the user sits down on the hip and the back is lying down, but since each user's body shape is not the same, the comfort effect can be provided is not high. Therefore, in recent years, the flexibility of the interlocking operation of a wire is established; between the chair and the elastic foam, the 俾 can adjust the curvature of the elastic = = the curvature of the elastic foam should be used accordingly. The back of the person, so can be matched with the user of the second to achieve better benefits, but for the user's waist ° ° can not get the supporting role _ empty state (back of the chair, although April 15, 1998 repair (committee) The positive replacement page can be adapted to the user's back curve, but cannot fit the user's waist. Therefore, it is prone to backache after sedentary. In addition, although the general chair has the structural design of the lifting and lowering adjustment (especially the office chair), the table used in the general case cannot be adjusted in height, so the user can only adjust the height of the chair. The height of the table is adjusted, so for a taller user, when the foot is placed on the ground with a proper sitting posture, the lower part of the thigh is suspended above the seat cushion without any support, so often There is a problem of acid and tired legs. In view of the above problems, the inventor of the present invention deeply understands that the cushion structure design of the conventional chair can achieve the adjustment function conforming to the curve of the back of the human body, but the waist curve of the human body cannot be caught by the back of the chair, and the branch of the seat cushion The effect is also obviously insufficient. Therefore, with its many years of experience in the creation and design of chair sets, the company actively develops and improves. Under the careful consideration of various conditions, it finally creates the structure of the invention, which will be read. Missing. SUMMARY OF THE INVENTION The present invention is an improved cushion structure of a chair, which is mainly an elastic pad which is provided with wires on both sides of a seat back plate and a seat cushion plate, and can be respectively operated under the extension and contraction operations of the wires. Driven by the change of the elastic 塾 curvature of the seat back plate and the seat sill plate, the following effects can be obtained by the implementation of the following: The elastic back pad which is operated by the wire on both sides of the front side of the chair back plate of the present invention is relatively arranged.俾In order to replace the page position on the sides of the waist when the user sits down, 1373317 _ 98 April 2014 (*), the extension of the wire can be made when adjusting for different fat body users. Under the shrinking operation, the curvature of the elastic backing pad is changed to be arched inward or outwardly, thereby pushing and changing the curvature of the elastic foam to fit and bear the size of the user's waist, so that a complete branch can be provided. The purpose of the user's waist is selected, and in the seat cushion portion, the elastic pad on the seat cushion plate can also be arched through the wire operation, and the elastic foam can be pushed to fit and support the user's thigh. Significantly enhance the comfort of the child chair # 'and play a positive user guide sitting position function (the seat back to encircle the waist of the user and both sides remain upright), to prevent users from skewed because of sitting and influence the future development of bones. [Embodiment] In order to enable the examiner to clearly understand the structural composition of the present invention and the functional benefits that can be achieved, the rest will be described in detail with reference to the drawings, and the detailed description will be as follows: • The present invention is a cushion for a chair. The body structure is improved, mainly in the front side of the chair back plate 1 covered by the elastic foam 5, and the elastic 塾 2 is arranged in the opposite direction (as shown in the first figure, attached to the chair back plate) The elastic foam 5 and the covered cloth cover of the raw mat 2 are the inevitable structure of the conventional one, so they will not be described again), and the guide wire 4 can be controlled to extend through the adjuster 4, The contraction operation is used to drive the curvature of the elastic jaw 2 to be supported and attached to both sides of the user's waist to achieve the purpose of the auxiliary bridge sitting posture. 5 April 15, 1998 repair (熹) replacement page by the composition of the above components, the elastic pad 2 is an arc-shaped elastic plate (as shown in the first figure), the two ends of which are connected by wires 3 In the change of the extension and contraction length of the wire 3, the distance between the two ends of the elastic pad 2 is changed (as shown in the third figure), and then the curvature of the elastic full arch is adjusted to produce a corresponding change, so it is set on the back of the chair. The elastic pad 2 which is oppositely disposed on both sides of the front side of the plate 1 can be in contact with the sides of the user's waist via the elastic foam 5, and when the adjustment is made, the wires of the elastic ridges 2 on both sides can be synchronously adjusted via the adjuster 4. 3 stretches and contracts, so that the curvature of the elastic pad 2 changes and expands inward or outward (as shown in the fourth figure), thereby changing the arc state of the elastic foam 5, so that it can be adjusted via the elastic pad 2 In order to adjust the width of the waist of the user, the elastic pad 2 can push the elastic foam 5 to deform and fit the waist of the user to support and support the waist of the user, so that the user's waist Will not be presented with the back of the chair It is suspended and cannot be supported, so there is no problem of sedentary and sedentary. Furthermore, since the elastic ridges 2 on both sides of the back of the seat back are disposed in a relative state, the user can naturally play the function of guiding the position of the squatting seat after lying down, preventing the squatting person from sitting in a skewed posture. It affects the development of bones in the future. In addition, in the structure of the seat back 10 of the present invention, an elastic pad 6 (shown in FIG. 5) in an up-and-down state can be added in the middle of the elastic pads 2 on both sides, and the cymbals are respectively provided corresponding to the waist and the back of the user. Adjusted support to provide a more comfortable seat back design. On April 15, 1998, the repair (US) is replacing the page. In the above description, the wires 3 of the elastic pads 2, 6 on both sides and in the middle can be operated more easily, and the adjuster 4 of the control wire 3 is controlled. The conventional two-in-one structure can be adopted, that is, the mandrel of the adjustment button 4 is a tooth that can be selectively inserted into one of the two worms 4 3, 4 4 to drive the side of the tooth 5L reel 4 5, 4 6 (As shown in the sixth figure) 'The other end of the wire 3 connecting the elastic pads 2 on both sides is combined with the same toothed reel 45 and can be wound up' and the wire of the intermediate elastic pad 6 is combined with another - On the toothed reel 4 6 , after the toothed reel 45 is driven by the adjusting button 4 i, the elastic 塾 2 on both sides can be synchronously adjusted, and the mandrel 4 of the adjusting button 41 enters the other screw 4 4 . When formed to drive the toothed reel 46, the intermediate elastic pad 6 can be driven to produce a change in curvature (as shown in the seventh figure). Furthermore, the cushion structure of the chair of the present invention can be a design of the seat cushion 2 ,, and the elastic cushion 2 which is connected with the wire 3 on both sides of the front edge of the upper edge of the 弹1 (As shown in the eighth figure), the wire can be controlled by the adjuster 4; 3 is extended and contracted to drive the curvature of the elastic pad 2 to change, so that the elastic pad 2 on the seat pad 201 is arched.俾 Push the elastic foam 5 pairs to fit and the thigh of the user of the branch (as shown in the ninth figure), thus greatly improving the comfort of the chair. Further, the elastic pad 2 on the seat cushion 20 is disposed in a juxtaposed state on the front edge of the seat cushion 201, so that the curvature of the elastic pad 2 has a more direct bulging effect when pushed against the elastic foam 5. . 1373317 April 15th, 1998 曰 repair (*) is replacing page [Simple description of the drawing] The first figure: is the structural diagram of the present invention.
