Creation instructions (3) The groove portion 31 is included in the U-shaped groove portion 31 on the rib portion 21 so that the swing arm 3 can be guided when it swings. The upper side of the upper arm of the swing arm 3 is provided with two opposite ear portions 3 2 convexly, and a lever 4 is pivotally fixed to the ear portion 3 with a pivot pin, and is sleeved on the pivot pin. The spring 35, and the two ends of the spring 35 are respectively pressed against the swing arm 3 and the handle 4 so that the toggle end of the handle 4 swings against the swing arm 3, and is also provided on the inner side of the swing arm 3. The ear part 41 is provided with a positioning post 3 4 to be pivoted on the ear part 41, and then the positioning post 3 4 is passed through the perforation 3 3 provided on the swing arm 3 and can be inserted into the side provided on the armrest 2 Any of the positioning holes 22 are on. In addition, a fan-shaped convex body 36 ′ is convexly protruded on the inner side surface of the upper end of the swing arm 3, and another fixing seat 71 is fixed on the seat back 5, and a corresponding one of the fan-shaped convex bodies 36 is disposed on the fixing seat 71. The fan-shaped groove 72 is provided with elastic elements 73, 74 at both ends of the inner portion of the fan-shaped groove 72, so that when the convex body 36 is inserted into the fan-shaped recess 72, the elastic elements 73 and 74 on both sides are just right Press tightly on the 7 ends of the convex body 36 to keep the convex body 36 in the middle of the fan-shaped groove 72, and then set a screw 6 from the swing arm 3 through the arc-shaped guide hole 2 3, and then screw into the fixed seat 7 丨The above structure is an elastic rotation device 7, so that the seat back 5 is maintained at a specific degree, and has a function of elastic rotation reset. P holds 1 疋 with 1 配合 and then cooperates with the third and fourth figures, as shown in the figure, when the occupant is fully seated at ^ ^ the last day ', you can manually pull the lever 4 on the swing arm 3 outward, and two = The post 34 exits the positioning hole 22 on the armrest 2, so that the swing arm 3 can be swung, so that the seat back 5 can be adjusted for the front and rear depth position. That is, after the month 5 is adjusted to the required depth position, Let the hand release the turning of the handle 4 to cause the positioning post 34 to be inserted into the other positioning hole 22 again, =
