New description: 【New technical field】 This creative department has improved the structure of the back of the chair. The main back of the chair is composed of the back frame and the cushion m (four). The grain is the frame for the f plate. The body ' has a backrest corresponding to the waist of the user, and the cushioning bracket is fixedly connected via the base and extends upward to the rear end of the back frame, thereby facilitating the pivoting of the top end of the cushioning bracket and the indignation. And on the struts between the struts, the shackles that are connected via the elastic segments, so that the yokes are connected to the top end of the back frame and the rear end of the sinus, the lie can be lie on the backrest The force prompts (4) the money can be driven by the yoke and the _ elastic section is deformed forwardly, so that the top end of the seat back frame can swing forward, so that the limb change of the entire seat back frame can help the back of the langer. Keep the user in a good sitting position. [Prior Art] Although the seat has many structural types according to different usage requirements, it is necessary to provide a seat back under the requirement of comfort. Therefore, whether the design of the seat back is good or not will determine a seat. Comfort. In the design of the back seat structure, the main one is composed of a back frame with a back frame (the material of the back plate can be built-in foam or mesh), and the material is buffered to enhance the person. When you are lying down, it is the most common chair back design, but it can't have ergonomic performance. Therefore, even if the user's sitting position is not good, it can't have any positive effect of M336733. It is often the case that the user gets more and more tired, which is because the seat back of the conventional seat lacks the problems arising from the ergonomic design. In view of the above problems, the creator deeply feels that the seat back of the seat has a design that relies on the function of the back of the human body, and therefore it is necessary to have a guiding effect when the user is in a bad posture, so that the function of the seat back can be achieved. After getting the 'good performance, so I have been engaged in the professional design and manufacturing experience of the chair for many years, actively researching and improving, and under the careful consideration of various conditions, I finally created the composition of the structure and the structure, which will completely solve the problem. Missing. [New content] This creative department is a kind of chair back structure improvement. The chair back is mainly composed of a seat back frame and a cushion fixing frame. The seat back frame is a frame for setting the back plate, and the back cushion is arranged. There is a curved design of the forward embossing, and the cushioning is fixed by the base and extends upward to the rear end of the back frame, and the top and the middle sections of the smashing fixing are respectively provided with pivoting portions and The struts are complemented by the shaft section, which urges the _ wire to be pivotally connected to the top end of the chair's county and the rear end of the top of the back cushion, so the following effects can be achieved after implementation: The back of the chair is composed of a back frame and a cushioning bracket, and the back frame is inserted into the punching frame at the rear end position of the top end and the back end of the back cushion, and the back cushion is corresponding to the use. The position of the waist of the person, when the user's back is in a bowed state, the poor sitting position lies against the backrest. ·«. 'The top of the back frame can be M336733 to pull the elastic section again and again. Deformed forward, so that the top of the seat back frame produces a forward swing function, allowing the chair The frame angle can be more easily attached to & ^ Jie user 'thereby changes the angle of the entire seat back frame is generated by using hold back effect, promoting the user to maintain a good posture so. [Embodiment] In order to enable your review committee to clearly understand the structure of the creation and the benefits achieved by it, the rest will be accompanied by a diagram to illustrate the examples, and the details will be explained as follows: The back structure is improved, and the back of the chair is mainly composed of a seat back frame 1 and a cushion fixing frame 2 (as shown in the first and second figures), wherein: the chair frame 1· is - a frame for the back plate The body has a backrest 3 at the front of the user's waist, and pivot plates 11, 12 at the top end of the frame and the rear end of the top of the back cushion 3. The cushioning fixing wire 2 is a rod extending upwardly to the rear end of the seat back frame 1 via the base 4, and is provided with pivoting portions 2 1 and 2 2 at the top end and the middle portion, and the connecting rod therebetween The upper part is connected via the elastic section 23. With the above-mentioned components, the seat back frame P is pivotally connected to the splicing portions 21, 22 of the buffer fixing frame 2 by its pivoting plates, jade and work 2 (as shown in the third figure), and the seat back frame is urged. 1 The composition of the creation can be completed by forming a cushion on the chair by the buffer holder 2. Therefore, after the implementation, the seat back frame 2 can be used for the user's back to lean on the M336733.
而提供良好的支撐力及舒適性，而在使用者的背部以曲弓 狀態的不良坐姿躺靠在背靠塾3時，由於背靠墊3是集中 受到壓迫力’而背靠塾3的位置又是位於樞接板工2的下 方，且因為緩衝固定架2兩樞接部2 1、22之間具有彈 性段2 3之設計，所以此—躺靠力將可推動椅背架i的底 端向後偏擺，而椅粒1的頂端可以受到此-旋動力而拉 動彈性段2 3向前撓曲變形（如第四圖所示），使得椅背架 1的頂端產生向前擺動之功能，讓椅背架1的角度可以更 容易貼合·者背部，藉糾整㈣料1㈣度變化產 纽住使用者背部的作用，促令使用者再度維持良好的坐 姿，而在者以射部上相靠射架丨上方時，則藉 由彈性段23可撓曲之特性可令椅背架^底端向前偏擺 (如第五圖所示）’促令背靠墊3可以往前支撐使用者，達 到良好的舒適性。Providing good support and comfort, and lying on the backrest 塾3 in the wrong sitting position of the user's back in the state of the bow, because the back cushion 3 is concentrated against the pressing force' while leaning against the 塾3 position It is located below the pivoting plate 2, and because of the design of the elastic section 23 between the two pivoting portions 2 1 and 22 of the cushioning bracket 2, the reclining force will push the bottom end of the seat back frame i Backward yaw, and the top end of the chair granule 1 can be subjected to this-rotational force to pull the elastic section 2 3 to flex forward (as shown in the fourth figure), so that the top end of the seat back frame 1 generates a forward swing function. The angle of the seat back frame 1 can be more easily fitted to the back of the person, and the effect of the user's back is promoted by the correction of the (four) material 1 (four) degree, so that the user can maintain a good sitting posture again, and the person is on the shooting part. When the top of the frame is close to the top of the frame, the bottom of the back frame can be deflected forward (as shown in the fifth figure) by the flexible deflection of the elastic section 23 (the backrest pad 3 can be supported forward). For good comfort.
另又，為因應不同使用者的體型不同，椅背架工的兩 側是各設有連續轉1 3 (如第六騎示），耐靠塾3兩 端則是對應設有凸弧段31，俾可經由壓條3 2把背靠墊 ^凸弧段31覆固於連續弧槽13中形成執接，藉以令 背罪墊3可以相對椅背架i進行上、下位置調整之功能者。 、、再者’背靠塾3是為内置泡棉之彈性緩衝材質，俾以 增進使用者躺靠的舒適性。 M336733 【圖式簡單說明】 第一圖：係本創作之組成狀態圖。 第二圖··係本創作之結構圖。 第三圖：係本創作之結構組成圖。 第四圖：係本創作之實施狀態圖。 第五圖：係本創作另一實施狀態圖。 第六圖··係本創作背靠墊之組成圖。 【主要元件符號說明】 1 :椅背架 1 1 •框接板 1 2 ·’柩接板 1 3 :連續弧槽 2:緩衝固定架 2 1 :樞接部 2 2 ·枢接部 2 3 :彈性段 3 :背靠墊 3 1 :凸弧段 3 2 :壓條 4 :底座 1 0 :椅背In addition, in order to adapt to the different body types of the different users, the sides of the back frame are provided with continuous rotations 1 3 (such as the sixth riding display), and the opposite ends of the 塾3 are correspondingly provided with the convex arc segments 31. The crucible 3 can be attached to the continuous arc groove 13 via the bead 3 2 to form a joint, so that the sin mat 3 can perform the upper and lower position adjustment functions relative to the seat back i. And, the backrest 塾3 is an elastic cushioning material for the built-in foam to enhance the comfort of the user.
