New description: [New technical field] The present invention relates to a tilting linkage between a seat back and a seat cushion of a seat chair, that is, when the occupant leans back against the seat back and leans back, The seat portion also tilts slightly backwards, so that the occupant's back and buttocks are always in an optimal contact state without the discomfort of dislocation friction. [Prior Art] The back of the chair of the general office chair has the function of adjusting the reclining angle -·, but the seat cushion of the ride can be adjusted to the height of the ride. It is impossible to make further adjustments, that is, when the back of the chair is tilted backwards, the seat is still only placed in the original position, so the relative dislocation occurs when the back of the occupant leans against the back of the seat. In the mobile county, the relative displacement of the back of the silk-sitting person produces a relative displacement of friction. Even the occupant may cause the hips to slide due to the change in the posture. In addition, as for the patent of CN200820008020, it includes a front guiding groove at the front end of a base unit for the front end of the riding unit, and the front end of the county unit _ downward extension a rear portion of the rear end of the backrest unit is pivoted together with the extension portion _ and a member is placed on the V backrest unit to make the rod Both ends of the piece are placed in the rear guide groove on both sides of the rear end of the riding unit; therefore, when the seat back unit performs the tilting adjustment of the required angle, the relative position of the recording unit can be moved before and after the scale is near horizontal level. The original purpose is to make the occupant's hips, back and the unit and the chair # unit do not move and rub relative to the misalignment, and adjust the lin #. 3 M429421 M429421

The unit on the t is moved forward, which in turn makes the misalignment between the occupant's back and the chair f more serious. It also fails to meet the ergonomic 22nd. Even if the occupant can achieve the purpose of lying on his back, his body must also claim to be moving, or the back of the chair can be tilted to the required angle. Relaxing on the shot, so the above design does not meet the original ° ° ° ° purpose ' also failed to allow the occupant to completely adjust the operation. [New content] The reason is that in order to improve the linkage between the front and the back (10), it is impossible to meet the ergonomic design and the problem of moving in the same direction. The new type is between the back of the chair and the seat cushion. The mobile design is linked so that when the shot is tilted, the miscellaneous movement will move back and forth, and the occupant can adjust the tilt of the seat back. # The technical solution adopted by the present invention is that a seat cushion and a seat back are respectively disposed on the upper side and the side of the base, and the seat back is disposed through a pivotal fixing on the rear side of the base=the seat back support frame And at the lower end of the seat back support frame, a pivoting portion is further provided, and the front and rear portions of the seat (four) face are slightly divided, and the rear pivotal portion and the seat back support frame of the seat back are further provided. The frame joints are solidified together, and the front (four) portion of the seat cushion and the secret arm portion of the base _ are pivotally connected by an arm. In the above solution, the front axle of the base is provided with a pivot hole provided with a sleeve, and the corresponding end of the connecting arm is provided with a shaft portion that is inserted into the sleeve, and then a screw is arranged in the base. The shaft portion of the arm is locked to the sleeve. - Therefore, by the above-mentioned pivotal connection of the door, the seat cushion and the door back support frame 4 卞·1Λ!, when the shot is tilted backward, the _ 塾 will also move with the slightest movement The maintenance step and the same direction between the upper body and the lower body 'do not have the feeling of friction and discomfort, or the need to move the body to adjust the position' and the county's body will sink slightly, so that the legs can be Relax properly. Therefore, the present invention can be fully understood by the following solids and is implemented: [Embodiment] Referring to the first and second figures, the present invention includes an upper end of a chair. A base 1 for supporting the seat cushion 2 and the seat back 3 is provided, and the base 1 mainly includes a front axle pivot portion 11 and a rear axle pivot portion respectively (front and rear) (not fully disclosed in the drawings, but It is located at the lower end of the seat back support frame 31, and the base is fixed at the position of the upright position. The front side and the rear side of the back side of the record 2 are respectively provided with a front pivot portion 21 and a rear pivot portion. 22, and the seat back 3 is mounted on the aforementioned seat back support frame 31, and the lower end of the seat back support frame 31 is fixed on both sides of the rear side of the base 1 as described above, and the seat back is A pivoting portion 32 is further disposed on both sides of the lower end of the support frame 31, that is, the rear pivoting portion 22 of the seat cushion 2 is pivotally fixed to the frame portion 32, and the upper end of the connecting arm 4 is further fixed to the seat. The front end portion of the pad 2 is fixed to the front end portion of the base member. In addition, as shown in the third and fourth figures, the front axle pivot portion 11 of the base cymbal is pivoted, and a sleeve 51 is disposed in the hole, and the corresponding portion of the arm 4 is convex. A shaft portion 41 is then locked by a gasket set 53 and a screw 52 from the inner side of the base 1 to the shaft portion 41 of the connecting arm 4 together with the sleeve 51, thereby allowing the connecting arm 4 to be in the front pivot portion η. Swing freely. Therefore, please cooperate with the fifth figure, when the occupant's back rests on the back of the chair M429421 ί (0.11
........ 3上而向後傾仰時，由於座墊2的前端是透過連臂4樞接 於底座1的前側處，而座墊2的後端則是與椅背支持架31的 鄰近下端處樞固在一起，讓座墊2不但會隨之稍為向後移動， 同時也會保持在乘坐水平的狀態下，進而讓乘坐者的上半身雖 然隨著椅背3的後傾而位移，但其臀部也因座墊2的後移動 作，讓乘坐者的上半身與下半身之間保持和協平衡的移動，故 令乘坐者可以完全放鬆全身地倚靠在椅背上，並同時進行傾仰 的調整，而無須再移動或調整身體的任何部位，即可完成所須 的傾仰調整的動作；同時讓座墊2也會稍微地下降，讓乘坐者 的身體略微下沈，使得乘坐者的腿部可以更為放鬆，進而令乘 坐者的全身可以更為舒緩放鬆。 儘管，上述的實施例已對本新型有較佳具體化的揭露與詳 述’皆為熟悉該項技術人士者所能清楚了解，而其所做的各種 型式及方法局部的改變，應都是沒有脫離本新型精神與範畤。 【圖式簡單說明】 可 第一圖是本新型的立體示意圖。 第二圖是本新型的立體分解示意圖。 第三圖是本新型的側視圖。 第四圖是第三圖的Α_Α處局部斷面示意圖。 第五圖是本卿射傾仰與座塾之間的連動示意圖。 【主要元件符號說明】 2.座塾，21.前樞固部，22.後樞固部， ，32.樞合部，4.連臂，41.軸部，51套 1.底座，11.前轴樞部，2』 3.椅背，31.椅背支持架，: 筒，52.螺絲，53墊圈組。 6. . . 3 when tilting backwards, since the front end of the seat cushion 2 is pivotally connected to the front side of the base 1 through the connecting arm 4, and the rear end of the seat cushion 2 is the back support bracket The adjacent lower end of the 31 is pivoted together, so that the seat cushion 2 not only moves backwards slightly, but also stays in the horizontal position, so that the upper body of the occupant is displaced with the reclining of the seat back 3 However, the buttocks are also moved by the rear of the seat cushion 2, so that the occupant's upper body and the lower body are kept in a balanced movement, so that the occupant can completely relax and lean on the back of the chair and simultaneously lean down. The adjustment can be done without having to move or adjust any part of the body to complete the required tilt adjustment; at the same time, the seat cushion 2 will also be slightly lowered, allowing the occupant's body to sink slightly, making the occupant's The legs can be more relaxed, which in turn makes the occupant's body more relaxed.
