New description: - [New technical field] 'This new type provides the seating part of the office chair, which can be used as an independent and backward movement and positioning control device, so that the seat back can be adjusted when the back of the chair is tilted at different angles. Get the right rider. [Prior Art] In addition to the adjustment of the back of the chair, the position of the seat can also be moved back and forth, and usually the seat is tilted with the back of the chair. The mechanism slides forward or backward, so the seat is unable to move forward and backward under the condition that the seat back does not move, so that the occupant independently adjusts the seat position, which greatly reduces the office chair. The convenience and variability of the adjustment, and the interlocking control between the above-mentioned seating position and the back of the chair also affects the distance that the riding portion can move, and thus the appropriate position of the riding portion, and the actual required requirements cannot be obtained. Therefore, some office chairs are also designed to be independently adjusted to the front and rear positions. However, different designs have different advantages, but their operation is mostly controlled by the side of the seat. , - Then, after the occupant releases the clamping of the riding part, the occupant can move the riding part by moving the waist and hips forward and backward, but since the chair of the office chair also slides, the ride Usually, the foot must be moved into the foot of the foot to move the seat smoothly, but the occupant's own weight is forced to the position of the seat, which may cause difficulty in moving the seat, so the occupant The buttocks will be lifted slightly to reduce the pressure on the seating area, and the hand will also grasp the movement of the front 5 M348541 end of the seating area. Therefore, when you want to adjust the seating position, you must first operate the side of the ride on the Qiu > ... position. 'The occupant's hand must be at the front end of the ride, so that the release can be repeated after the release, so that the hand can not be released. The pliers of the rider's seat is adjusted by the rider's section (4) or pulled, so that the operation is made:::=The push of the seat part is [new content] method, and the question is passed on the material port. Technical hand = 底 at the upper end of the chair foot and the ride single two, set with == to make the seat part can slide back and forth:: In the seat:! Pull the swing and - the end of the buckle with the buckle The shackle is fixed, and then the buckle can be included. The number of the corresponding position on the chassis of the door (4) is also set between the chassis of the present type and the seat portion, so that the seat portion can be automatically reset. According to the above-mentioned present invention, the fastening element provided at the front end of the seat portion = when the position adjustment is performed before and after the riding portion, the occupant can release the locking portion while pulling the fixed component while the hand is more pushable Or pull to assist the movement of the seat section' and also allow the occupant to stand up slightly in the mobile seating section, so that the center of gravity of the body is more stable, which makes the adjustment of the whole adjustment easier and smoother. The silk μ 'handle type can be fully understood by the lower touch _ and cooperated with it, and it is implemented according to the following: [Embodiment] M348541 ' Please refer to the first and second pictures, the office chair of this new pear The main body includes a chair leg 1 and a seating unit 2, wherein the upper end of the leg 1 is provided with a chassis 11 combined with the seating unit 2, and a locking portion 12 is disposed at the middle of the front end of the chassis 11, and is at the locking portion. 12 is provided with a plurality of positioning holes 13 , and the seating unit 2 includes at least a seat portion 21 and a seat back 22 , and a central portion of the front end of the seat portion 21 is provided with a pivot portion 211 and is pivoted - 211 The upper end of the fastening element 23 Φ is a grip portion 231, and a buckle portion 232 is protruded from the inner end end thereof, and the buckle portion 232 is correspondingly configured. After the fastening portion 232 passes through the positioning hole 13 at the same time, the buckle portion 232 can be inserted into the insertion hole 212 corresponding to the seat portion 21; and at the pivot portion 211. An elastic member 24 is disposed between the fastening member 23 so that the fastening member 23 can be made by the elastic tension of the elastic member 24. The end of the buckle portion 232 holds the swinging preload force that is pressed toward the lock portion 13. In addition, a sliding device 3 is disposed between the chassis U and the seat portion 21, and the sliding device 3 includes two sliding handles 31, and each of the sliding rails 31 is composed of two mutually fixed fixing portions 311 and sliding portions 312. And the sliding portion 312 can be slid on the fixed portion 311' and then the fixing portion 311 is fixed to the chassis 11, and the sliding portion 312 is fixed to the seating portion 21, thereby allowing the seating portion 21 to move back and forth . Next, a spring 4 is hung in the middle of the chassis 11, and the other end of the spring 4 is tightened to the seat portion 21 so that the seat portion 21 can be automatically reset by the elastic pulling force of the spring 4. 7 M348541 : Therefore, please refer to the third and fourth figures. When the occupant rides on the seat portion 21, the occupant can grasp the seat portion 21 regardless of whether the seat back 22 is to be tilted or not. The grip portion 231 of the locking member 23 at the front end causes the buckle portion 232 to be separated from the positioning hole 13, and the occupant can stand up and down to make the waist and hip move forward and backward, and at the same time, push or pull the hand in the hand. Under the action of the seat portion 21, the seat portion 21 can be moved forward or backward to a predetermined position. Then, the hand gripping the fastening member 23 is released, so that the buckle portion 232 can be re-fitted into the corresponding position. The hole 13 is also reinserted into the insertion hole 212, so that the seat portion 21 is fixed at the position to be adjusted; therefore, during the adjustment of the entire seat portion 21, the occupant uses the movement of the waist and hip, In addition to moving the seat portion 21, the hand is gripped on the front end of the seat portion 21, and the auxiliary movement of pushing or pulling is performed, which not only allows the movement of the seat portion to be smoother, but also allows the occupant to have a more center of gravity. Smooth, so the entire adjustment process is simpler . On the other hand, when the seat portion 21 is to be reset, the occupant's buttocks are separated from the occupant portion 21, and the buckle portion 232 is grasped by the hand to release the buckle portion 232 from the locating hole 13, thereby by the magazine 4 The elastic preload force causes the ride portion 21 to slide back to its original position. The above description of the embodiments of the present invention has been disclosed and described in detail as well as those skilled in the art, and the various changes in the various types and methods are not Leaving the spirit and scope of this new type.
