連動桿組320的多數連動桿除了以其一端匯集於聯結體326之外，多數連動桿的另一端即外端部則組設於撓性椅背200的後表面240，且其中至少一連動桿的外端部係浮動地推頂於撓性椅背的後表面。Most of the linkage rods of the linkage rod set 320 are assembled on the rear surface 240 of the flexible seat back 200, and at least one linkage rod is disposed at the other end of the plurality of linkage rods. The outer end is floatingly pushed against the rear surface of the flexible seat back.
在第1圖至第6圖所示的實施例當中，係顯示多數連動桿為一X形連動桿，其包括由聯結體326分別向左上方與右上方突伸的一第一連動桿321與一第二連動桿322，以及由聯結體326分別向左下方與右下方突伸的一第三連動桿323與一第四連動桿324。第一連動桿321與第二連動桿322的外端部分別連結於撓性椅背200之後表面240之上端部210的左側部260與右側部270(即大約對應於人體背部兩 側肩胛骨的部位)；第三連動桿323與第四連動桿324的外端部則分別浮動地推頂於撓性椅背200之後表面240之護腰部230的左側部260與右側部270(即大約對應於人體背部兩側之擴背肌的部位)。依此，使得人體的背部、腰部及其兩側較為突出的擴背飢及肩胛骨皆有所依靠及支撐。In the embodiment shown in FIGS. 1 to 6, it is shown that the plurality of linkage rods are an X-shaped linkage rod, and the first linkage rod 321 protrudes from the coupling body 326 to the upper left and the upper right respectively. A second linkage rod 322 and a third linkage rod 323 and a fourth linkage rod 324 protrude from the coupling body 326 to the lower left and the lower right respectively. The outer end portions of the first linkage rod 321 and the second linkage rod 322 are respectively coupled to the left side portion 260 and the right side portion 270 of the upper end portion 210 of the rear surface 240 of the flexible seat back 200 (ie, approximately corresponding to the back of the human body) The outer end portions of the third linkage rod 323 and the fourth linkage rod 324 are respectively floatingly pushed up to the left side portion 260 and the right side portion 270 of the waist guard portion 230 of the rear surface 240 of the flexible seat back 200 (ie, Approximating the part of the back muscles on both sides of the back of the human body). Accordingly, the back of the human body, the waist and the sides of the waist and the scapula are more prominent and supportive.
進一步，就支撐連動單元300其中第三連動桿323及第四連動桿324與撓性椅背200的浮動式接觸而言，係於第三連動桿323及第四連動桿324的外端部各樞設有一擴背肌支撐墊340，其分別浮動地推頂於撓性椅背200之後表面240之護腰部230的左側部260與右側部270。依此，第三連動桿323及第四連動桿324的外端部在相對於撓性椅背200所對應之人體的擴背肌部位乃可轉向，並給予浮動式的推頂支撐，因此，撓性椅背200在此部位乃可依人體背部姿態的調整而作相應的變化，並隨時提供有力的支撐。Further, in the supporting linkage unit 300, the floating contact between the third linkage rod 323 and the fourth linkage rod 324 and the flexible seat back 200 is at the outer end portions of the third linkage rod 323 and the fourth linkage rod 324. A reaming back muscle support pad 340 is pivotally mounted to the left side portion 260 and the right side portion 270 of the waist portion 230 of the rear surface 240 of the flexible seat back 200, respectively. Accordingly, the outer end portions of the third linkage rod 323 and the fourth linkage rod 324 are steerable with respect to the expanded muscle portion of the human body corresponding to the flexible seat back 200, and are provided with floating ejector support. The flexible seat back 200 can be correspondingly changed according to the adjustment of the human body's back posture, and provides strong support at any time.
亦即，在乘坐於座椅期間例如在辦公期間，人體常有半轉身、後仰伸懶腰或因久坐而調整坐姿的動作，支撐連動單元300除了能以其第一連動桿321及第二連動桿322提供人體肩胛部堅實的依靠之外，並能因連動桿組320與滑塊310活動樞接的設置，以及因人體倚靠於撓性椅背200的自然施力，使得第三連動桿323及第四連動桿324的外端部能以樞軸330為軸而相對產生一向前的推頂力量，且能以擴背肌支撐墊340之360度的轉動調節，而隨時穩實地支撐人體背部最大區域之擴背肌的部位，使人體在乘坐上極為舒適。That is, during the seated period, for example, during the office, the human body often has a half-turned body, a back-slung, or a sedentary posture, and the support linkage unit 300 can be linked with the first linkage rod 321 and the second linkage. The rod 322 provides a solid support for the shoulder portion of the human body, and can be pivotally connected by the linkage rod set 320 and the slider 310, and the natural linkage force of the human body leaning against the flexible seat back 200, so that the third linkage rod 323 And the outer end portion of the fourth linkage rod 324 can relatively generate a forward pushing force with the pivot shaft 330 as an axis, and can adjust the 360 degree rotation of the back muscle support pad 340 to support the human body back at any time. The largest area of the back muscles makes the body extremely comfortable to ride.
此外，依支撐連動單元300的設計，其連動桿組320係設於滑塊321而可隨其移動，當滑塊310及連動桿組320上下移動產生垂直位移時，由於其垂直位置的變化，又因撓性椅背200的下端部220已被固定，便可造成撓性椅背200水平縱深方向之距離的變化，從而使得撓性椅背200之護腰部230的位置產生了變化。亦即，使用者可調動支撐連動單元300，使其滑塊310於支柱100之滑槽121上下滑動，而相對地帶動撓性椅背200以其下端部220為支點，使其上端部210作上下的相應動作及變形，以及使其護腰部230作前後的相應動作及變形。In addition, according to the design of the support linkage unit 300, the linkage rod set 320 is disposed on the slider 321 and can be moved therewith. When the slider 310 and the linkage rod group 320 move up and down to generate a vertical displacement, due to the change of the vertical position thereof, Moreover, since the lower end portion 220 of the flexible seat back 200 has been fixed, the distance of the flexible seat back 200 in the horizontal depth direction can be changed, so that the position of the waist portion 230 of the flexible seat back 200 is changed. That is, the user can adjust the supporting linkage unit 300 to slide the slider 310 up and down in the sliding slot 121 of the strut 100, and relatively move the flexible seatback 200 with the lower end portion 220 as a fulcrum, so that the upper end portion 210 is made Corresponding actions and deformations of the upper and lower sides, and corresponding movements and deformations of the waist guard 230.
因此，依據支撐連動單元300及撓性椅背200的設計，可據以調整撓性椅背200之護腰部230的前後及高低位置，以配應使用者因不同高矮、或不同坐深位置、或因不同坐姿所產生之腰部所處的不同位置。例如，當人體乘坐於椅座500且其坐深處於較後位置時，使用者可將本發明其中之支撐連動單元300的滑塊310沿著支柱100的滑槽121往上調整，而相對帶動撓性椅背200的護腰部230往後調整，以支撐人體此時向後的腰部；當人體乘坐於椅座500上的坐深處於於較前位置時，則使用者可將本發明其中之支撐連動單元300的滑塊310沿著支柱100的滑槽121往下調整，而相對帶動撓性椅背200的護腰部230往前調整，以支撐人體此時向前的腰部。因而，不論人體處於何種姿態或坐深位置，依支撐連動單元300的調整，皆能使得人體的腰部獲得撓性椅背200之護腰部230有效的支撐及依靠，減低人體腰部的負擔，並使其乘坐舒適。Therefore, according to the design of the support linkage unit 300 and the flexible seat back 200, the front, rear, and high and low positions of the waist guard 230 of the flexible seat back 200 can be adjusted to match the user's different heights or different depth positions. Or the different positions of the waist due to different sitting postures. For example, when the human body is seated on the seat base 500 and the seat depth is in the rear position, the user can adjust the slider 310 of the support linkage unit 300 of the present invention upward along the sliding slot 121 of the pillar 100, and relatively move. The waist portion 230 of the flexible seat back 200 is adjusted backward to support the rearward waist of the human body; when the sitting depth of the human body on the seat 500 is in the front position, the user can support the invention.
