New description: [New technical field] The present invention relates to a seat back adjustment structure. The footrest, seat cushion and back of the chair are equipped with an adjustment device. The movable seat and the sliding seat are composed of the first pole and are fixed on the through holes of the living seat and the two sides of the base, and the yellow rod is worn in the base, and the second pole is arranged to be worn. Between the through hole and the limit groove on both sides of the movable seat and the base, the movable seat is pivoted on the base, and then the sliders on both sides of the sliding seat are swept into the sliding slot of the movable seat ► inside and the rod is worn by the adjusting rod The invention can be assembled by pivoting between the opposite through holes of the movable seat and inserting a fixed rotating shaft with a carding rib when entering the living contact. [Prior Art] In daily life, whether it is at home or at work, the chair can provide a comfortable space for the user to use, so the chair is an indispensable piece of furniture for our daily life, and the chair is bought when it is bought. And the shots are all determined, so that the makers will have an uncomfortable feeling when riding, and when the makers are still growing children, the chairs that are purchased by the equipment are often unable to be tested due to the growth of the users. The domain _ chair, so not only makes it impossible for a chair to occupy the living space, and its support (four) must be spent outside. In view of this, the creator developed a seat back that can be adjusted to the front and rear distance of the seat, and adjust the height of the seat back when moving, and the seat back can be adjusted or elastically oscillated according to requirements, in order to effectively improve The lack of knowledge. [New content] The main purpose of this creation is to provide a chair back adjustment structure. The chair's tripod, seat cushion and chair system are equipped with adjustment devices. The adjustment device is made up of the base and M337300 movable seat. And a sliding seat, which is formed by the first struts on the through holes of the movable seat and the sides of the base, and the spring is disposed at the bottom, and the second struts are placed on the movable seat and • Between the through holes on both sides of the base and the limit slots, the movable seat is turned over, and then the two sides of the slide are slid into the sliding slot of the movable seat, and the adjusting rod is worn and the green is fixed. When the movable seat is between the opposite through holes, and when it is inserted into the movable seat, a fixed rotating shaft with a carding rib is additionally worn, and when the card of the fixed rotating shaft is locked or loosened, The slider is moved in the chute to adjust the position of the seat back, and when the back of the seat is stressed, the movable seat is rotated around the first pole, and the second pole is rebounded by the spring force. , thereby causing the back of the chair to sway, and when the positioning rod passes through the base and wears the fixing hole of the movable seat, the fixed seat can be fixed The back can't shake. [Embodiment] The details of the creation and the technical means are described in detail with reference to the following figures: Please refer to the first and second figures, the chair's tripod 2, seat 塾 3 and seat back 4 The interlacing device is provided with an adjusting device 1 〇〇, which is composed of a base iq, a movable seat 20 and a sliding seat 30, wherein: the base 10 opens a plurality of relatively through holes on both sides. , the work 2 and the limit groove 3, and a rib 14 is protruded on one side. The movable seat 2 defines a plurality of opposite through holes 2 2, 2 3, and 2 4 on the side flaps 21, and another limiting slot 25, a fixing hole 26 and an opening slot 2, and two sides of the bottom end. There is a chute 28 . The sliding block 30 is provided with a plurality of connecting ends 3丄 on both sides, and is embedded in the recess 33 of the M337300 slider 32 by the connecting end 3 i, and a fixing portion 34 is protruded. When combining, the movable seat 2 〇 is sleeved on the lower end of the base work, and the first struts 4 〇 are inserted into the movable seat 20 and the base 10 - the through holes 22, 11 of the side, and then the - spring 5 . Then, it is fixed through the base 10 and the movable seat 2 〇 the other side through holes 11 and 22, and the 7th pedestal cup 41 is inserted into the movable seat 2 〇 and the through hole 2 3 of the side of the base 1 、, the limiting slot 13 'There is a limit slot for the other base 1 and the movable seat 2〇. The through hole ^ is pierced out and the mouth is fixed, and the end of the magazine 5 which is worn by the first rod 4 is clamped to the base 1 0. The rib 14 is attached to the second rod 41. And the positioning rod 42 is inserted into the limiting slot 25 of the movable seat 2 and the base! Through the hole! 2, the movable seat 2 is fixed on the base 1 Q' and then the sliding seat 30 is gradually inserted into the sliding seat 2 8 of the movable seat 2 Q and penetrated by an adjusting rod 43 It is fixed between the opposite through holes 24 of the movable seat 20, and when the tooth is inserted into the movable seat, the fixed rotating shaft with the locking ribs 45 can be worn, and the cost is created by the device (10) (such as the third _ The lower end of the base 1Q of the light device 1 〇0 is fixed to the stand 2, and the upper end is provided with a seat cushion 3, and the seat back 4 is fastened on the slide base 3. Continued to participate in the _ four words, the tank rod 4 3 fixed rotation shaft 4 4 card lion 4 5 not - with the seat 3 0 fixed part 3 4 card, the slide 3 〇 can be used in the movable seat 2 The end chute = 8 left and right adjustment position (as shown in the fifth figure), and the seat back 4 will move with it. When the seat back 4 is adjusted to the desired position, the adjusting rod 4 is rotated to fix the rotating shaft 4 Rotation, let the fixed _4 4 card _ 4 5 (4) can be clamped on the fixed part 3 1 of the sliding seat 3 Q to achieve the clamping effect, and because the sliding seat 28 of the movable seat 2 is inclined, When the seat back 4 is adjusted, the width of the cover can be adjusted and recorded, and the height can be adjusted (as shown in the sixth M337300), so that the user can use it according to the requirements. Further, as shown in the seventh figure, when the user rides and leans against the back of the chair 4, since the movable seat 2曰0 is pivoted on the bottom phantom Q, the first struts 4 Q are rotated, so that The second talent 4 1 and the spider 4 2 move downwards in the limit slots u and 2 5 of the base 1 and the movable seat 2 Q respectively, and the second pole 41 can be lifted by the elastic force of the spring 5 Q Back (as shown in the eighth and ninth figures), which in turn causes the movable seat 2◦ and the sliding seat 3〇 to sway, by which the seat back 4 will be swayed back and forth to provide a comfortable multiplication range, and when the positioning rod 4 2 When the base 10 is worn out and penetrated into the solid red 26 of the movable seat, the seat back can be shaken. , /τ, combined with the above-mentioned 'The creation of the Shina structure has indeed turned to the 2 sense of the breakthrough formula, and has the implementation direction of the first creation, while at the same time able to achieve the practical blood on the production # is more suitable for industrial use The principle is novel and progressive, and it is in line with the requirements of patent application. In addition, the specific embodiment of the present invention is not limited to the embodiment of the invention, and the content of the technical section is used for the implementation of other equal functions.
