It is advantageous here that, if the nut 2 C is tightened by the transverse bolt in the corresponding recessed hole on the inner side of the frame strip, the nut can be fixed to the sheet I and the frame strip. According to another embodiment of the invention, the tensioning frame is provided with a tilt bearing such that the sheet can swing against the % month outer frame. It is advantageous here that the hand wheel can be arranged on the outer side of the seat back in the axial direction of the frame I. It is particularly advantageous to provide =H' to the left side of the seat back in the axial direction of the tensioning bearing of the tensioning frame. According to another embodiment of the invention, the tensioning bearing of the tensioning frame allows the elastic planar body to fit the back of the user. Adjusting the tilt position further enhances seat comfort. Therefore, the elastic flat body of the tension frame can be deformed on the one hand, and can be tilted with the back on the other hand to achieve high ergonomics and chair comfort. According to another embodiment of the present invention, the tilt bearing includes at least one (especially two) radial grooves on the side frame side frame strip of the seat back, at least one (especially two) guide rods passing through the groove Slots are connected to adjacent tensioning frame strips. This groove allows the tensioning frame to swing. The end of the groove constitutes the braking portion of the two guide rods, and the swinging motion of the tension frame can be restricted. According to an advantageous embodiment of the invention, a raft is provided on the inside of the tensioning strip, the guide rod being inserted into or connected to the cover. When the nut or threaded sleeve is placed on or inside the tensioning strip, it reduces the structure of the seat back and can be secured by the cover to prevent it from falling out. 1 312 ΧΡ / invention manual (supplement) /97-01/96138448 200836672 Particularly advantageous I, each with a - heart chair frame side frame and adjacent tension frame edge strip movement is shocked; , f: It is a rubber piece 'to make the tension of the tension frame flexible. Remarks: 3 series passed through the rubber piece. The rubber member is preferably a rubber member, so that the brakes in both directions of the guide rod are damped. A bearing, especially between the shaft hole of the side frame of the needle roller outer frame, is provided with f. When the upper part of the right outer frame is also provided with an elastic plane body, the seat comfort can be improved. According to the present invention, another right-hand apricot back frame, the back of the chair 4: two is set in a chair into the # use will touch the height of the seat back, and can be adjusted with the user's body south step by step Seat comfort. If:: There is a hand wheel on each side of the outer frame, which has reverse thread, also ^, work thread and - right thread, you can rotate the two hands / wheel ' in the same direction to relax or tension the elastic plane body . Also related to the back of the chair, which comprises a moon frame with two side frame strips, and a tension frame with two side strips in the outer frame of the seat back, wherein the two of the back frame are An elastic plane body is disposed between the side frame strips and the two side strips of the tension frame. The elastic flat body and the waist have high comfort.隹保月口ρ This invention relates to a type of seat, in particular a swivel chair having the above-described seat back. Such a seat or swivel chair has the advantages of the above-described seat back, and these advantages are not enumerated in order to avoid it. 312 ΧΡ / invention specification (supplement) / 97-01 / 96138448 200836672 The embodiment of the invention is described in detail. Figure 1 shows a perspective view of the seat back 100 of the present invention. The seat back (4) of the present invention comprises - strip 11, 12, and July outer frame 1, which has two side frame portions with an arc opening, an upper end, a curved upper horizontal frame strip, and an lower strip (1) 12: 'frame The strips are connected to each other. The lower horizontal frame strip 14 is connected to the side frame at the end of the section. There is a rotatable hand wheel 6a and 6b. In addition, the 'chair frame frame 包括 still includes one piece that protrudes into the side frame bar η, 12 and the lower part of the frame Ή 仏 仏 仏 仏 Α Α Α Α Α Α Α Α Α Α 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍The chair back frame 1 is disposed on the upper side of the side frame strips η, 12: a tensioned elastic first plane body 15 is formed between the chair frame 0 and the moon frame A (4) tensioning frame 4 is provided at the lower third of the 1 and the basin can be tilted. The 张-shaped tensioning frame 4 has two tapping strips 41, 42 parallel to the side frame strips /, 12, and a connection The horizontal strips 43 of the two side strips are bent backwards. A tensioned second flat body 44' is formed between the side strips 4b to form the waist. The hand wheel 6a and 6b can be used to adjust the n-shaped sheet. Edge strips 41, 42 of the frame 4; rotation The hand wheels 6a and 6b can open and close the side strips 41 and 42 to each other, so that the second plane body 44 can be relaxed or tensioned according to the needs of the user. Rotating the hand wheels 6a and 6b can make the side strips 41, 42 are opened and close to each other by the elastic deformation of the horizontal bar 43, thus changing the distance between the edge strips 41, 42 at 312/invention specification (supplement)/97-01/96138448 8 200836672. Each of the chair backs (10) of the embodiment of the invention can be moved by about G.8cm, so that the distance difference between the two handwheels 6a and 6b, 42 can be reached (5). Rubber edge = strip 42 Damping member. The boat takes the 41. In the example, the two handwheels 6a and 6b have reverse threaded left and right threads, so the two handwheels 6a and 6b can be rotated one by one. Or tensioning the second planar body 44.
