New description: [New technical field] This creation is about a seat structure, especially a seat that can be applied to a variety of seat cushions and seat backs, and can provide a large angle of the seat back. The designer of the seat joint structure lying on and lying. [Previous technology] \ Press, the types and styles of the current seats are various, and the structure of a seat can be lying on the back as shown in the first figure, which is a pedestal 2 spring and base 2 0 Pivot joints, the pivot joint is the front pivot joint, and the middle of the swing seat 2 2 is attached to the pivot seat 2 〇 2 fixed on the rear end of the base 2, and the pivot joint is set as the rear The pivot point, and then the front end of the swing seat 2 2 is pivotally connected to the base 2 1 , and the pivot joint is a central joint, and the seat cushion is fixed on the base 20 , and the seat back is fixed on the seat The seat 2 2 is placed; therefore, when the occupant intends to lie back, the base 2 of the fixed seat is tilted downward at the center of the previous pivot point, and the swing seat 2 2 is connected to the center of the center joint. The hem swings, creating an angle between the seat cushion and the back of the chair, and automatically adjusts appropriately as the occupant's posture changes. [New content] Although the seat cushion joint of the formula can be automatically adjusted according to the change of the occupant's posture, only because the seat 2 2 is pivotally connected to the rear end of the base 2, the seat 2 is 2 will be affected by the base 2 2 and limited to the angle of the recline. The reason is that the main purpose of this creation is to provide a seat structure for the seat reclining angle, which mainly includes a seat cushion base, a seat back mount M325779, a stepless positioning device and a torsion spring; The rear end of the base of the seat cushion is pivoted to the seat back mount, and the base of the cushion base is transversely disposed with a stepless positioning device, and the torsion spring 4 is sleeved on the pivot shaft, and the two ends respectively are respectively offset by $ The seat back base and the seat back fixing seat are provided on the bolt shaft for the stepless positioning device positioning piece bushing, and the seat cushion base and the seat back fixing seat are used to release the stepless positioning device with the pivot axis as the axis. The reclining angle of the seat back mount can be provided by the elastic force of the torsion spring. Therefore, since the joint seat of the present invention is a separate device, it can be applied to a seat in which the seat cushion and the seat back are separated, and the seat back can be provided due to the unrestricted characteristics of the joint of the present creation. The larger reclining angle, in addition, since the joint of the present invention has a segmentless positioning device, the reclining angle can be positioned by the stepless positioning device when the angle of the reclining is appropriate. The following is a further description of the preferred embodiment of the present invention, so that those skilled in the art of the present invention can be implemented according to the statements in this specification. [Embodiment] As shown in the first to second figures of the present invention, the present invention provides a joint structure for a seat reclining angle. The joint 10 includes a seat cushion base and a seat back mount 12. A stepless positioning device 13 and a torsion spring 14; wherein: ~ the seat cushion base 1 1 is generally a door shape, and the upper end edge thereof is formed with a plurality of fixing holes ii 与 for locking with the seat cushion, and At the rear end, a seat back fixing seat 1 2 is vertically pivoted by a pivot 1 1 1 , and a stepless positioning device 1 3 is disposed transversely in the seat cushion base 1 1 ; 6 • M325779 The chair (3) The solid seat 1 2 ' is pivotally connected to the rear end of the seat base 1 1 , and can be formed into a plug groove shape, and can accommodate a plug seat which is connected with the back of the seat and is locked after being placed. Further, at the lower end position thereof, a bolt shaft 1 2 1 which is coupled with the positioning piece 13 0 sleeve of the stepless positioning device 13 is provided; the stepless positioning device 13 is horizontally disposed in the base of the seat cushion base ( Since this is a conventional technique, it will not be described here, and the tension positioning action can be controlled by a lever 131. _· The torsion spring 14 is sleeved on the seat base 丄i and the pivot 1 1 1 of the seat back fixing seat 12, and the two ends thereof are respectively abutted on the seat cushion base worker and the seat back fixing seat 1 2- For the stepless positioning device 3, the positioning piece 3 is connected to the bolt shaft 121 of the bushing, and the seat cushion base ii and the seat back fixing seat 12 are disengaged with the pivot 1 1 1 as the axis. When the positioning device 丄3 is used, the reclining angle of the seat back mount i 2 can be provided by the elastic force of the torsion spring 14. With the above-mentioned components, please refer to the fourth and fifth maps. This creation can have the following advantages: 1. Since the joint 1 of this creation is a separate device, it can be applied. On a seat with a variety of seat cushions and seat backs. 2. Because of the unrestricted nature of the joints of this creation, it is possible to provide a larger reclining angle of the seat back. 3. Furthermore, since the joint of the present invention has a stepless positioning device 13, the position of the reclining angle can be positioned by the stepless positioning|positioning 1 to the appropriate reclining angle. x In summary, this creation has its excellent progress in the same kind of products. It also uses the technical information about such structures at home and abroad. The same structure does not exist in the literature. Therefore, this creation has already possessed new types of patents, and applied for it according to law. The above-mentioned ones are only the preferred and feasible embodiments of the present invention. Therefore, the equivalent of the application of the present specification and the scope of the patent application should be included in this creation. Within the scope of the patent.
