In order to make the present invention more clear and detailed, the preferred embodiment and the following drawings are used to describe the structure and technical features of the present invention as follows: the direction indications mentioned in the specification, such as "front", " "Back", "Left", "Right", etc. all correspond to the direction recognition of the user in the use state.

As shown in FIGS. 1 to 5, the seat back structure of the present invention is an integrally formed structure comprising a base 10 and a seat back 20.

The base 10 is formed to be coupled to a seat 30, and the base 10 is provided with a plurality of slots 11 for corresponding combinations with the seat. The base 10 can be made of plastic.

The seat back 20 extends upward from one side of the base 10 and is formed as a saddle-shaped seat back. The shape of the seat back 10 is a concave surface (shown in FIG. 5) from a vertical axial direction of the seat 30, and is a convex surface as seen from the horizontal axial direction above the seat 30 (as shown in FIG. 4). The seat back 20 includes a seat back frame portion 21 and a backrest surface portion 22 that extend inside the seat back frame portion 21 and are alternately formed in a mesh structure. The seat back 20 is made of plastic of the same material as the base 10, and is integrally formed with the base 10, that is, the base 10 is integrated with the back frame portion 21 and the backrest portion 22 of the seat back 20. The side surface of the seat back frame portion 21 and the backrest surface portion 22 on the front side of the seat back 20 is a continuous same surface. The backrest surface portion 22 may be a mesh structure formed by laterally and longitudinally intersecting, but not limited thereto, such as a mesh structure formed by obliquely intersecting or a honeycomb structure having a honeycomb shape, and the foregoing mesh structure may be A network structure formed by uniformly arranging equidistantly or a network structure formed by non-uniformly non-uniform alignment. According to the needs of use, the back of the seat back 20 The thickness of the frame portion 21 can be selected to be larger than the thickness of the backrest portion 22, but not limited thereto, for example, the thickness of the back frame portion 21 is selected to be equal to the thickness of the backrest portion 22. As shown in FIG. 6, the backrest portion 22 of the seat back 20 is further provided with at least one pattern area 23 for indicating a predetermined or related text or figure, wherein the pattern area 23 is attached to the net of the backrest surface 22. The structure is integrally formed, and the surface of the pattern area 23 can be convex, concave or flush with the mesh 221 provided on the aforementioned mesh structure.

As shown in FIG. 1 , a space 24 is formed between the base 10 and the seat back 20 , and the space 24 is located at the lower end of the back frame portion 21 of the seat back 20 . The space 24 structure thus reduces the amount of material used, and thus the overall weight is reduced, and provides an effect of enhancing flexible bending when the seat back 20 is pressed against and pressed.

As shown in FIG. 7, in order to be more comfortable and beautiful, an outer sleeve 40 is sleeved on the outer side of the seat back 20, and the outer sleeve 40 includes a gas permeable member (such as a mesh cloth) or a cold-proof member. The outer sleeve 40 has a sleeve 41 through which the seat back 20 can be wrapped in the outer sleeve 40, and the outer sleeve 40 is sleeved on the seat back 20, and the outer sleeve is The sleeve 41 of the 40 is properly bundled and then stored in the space 24, and the seat 30 is fitted to cover the sleeve 41 of the outer sleeve 40 in the space 24. In this embodiment, the sleeve 41 of the outer sleeve 40 can be completely received in the space 24 without being exposed to enhance the appearance thereof, and in the prior art, the mesh cloth kit is used to cover the back frame, and then After the edge of the mesh kit is “fixed and fixed”, the “fixed edge” position will still be revealed, thus reducing the overall appearance.

As shown in FIG. 8 and FIG. 9, in order to be more comfortable, a pillow 50 is disposed in front of the seat back 20, and the pillow 50 is preferably elastically mounted on the front side of the seat back 20, as shown in the figure. The pillow 50 is correspondingly mounted on the backrest portion 22 of the seat back 20. The contour of the pillow 50 conforms to the backrest portion 22 of the seat back 20 and is substantially saddle-shaped. As shown in Figure 9, in order to make the pillow A plurality of fastening holes 51 are disposed on the rear side of the pillow 50, and each of the fastening holes 51 is provided with a buckle 52 that can be fastened to the fastening hole 51. The pillow 50 is fastened by the meshing hole 221 of the mesh structure of the backrest surface portion 22 by using the buckle hole 51 and the buckle 52 to sandwich the backrest surface 22 of the seat back 20 with the buckle 52 and the pillow 50. Between the pillow 50 and the backrest portion 22 is firmly coupled. In addition to the bonding technique using the buttonhole 51 and the buckle 52 as exemplified above, other bonding techniques that are known to those of ordinary skill in the art to which the present invention pertains may be applied to the present invention, and are not described herein.

According to the disclosure of the chair back structure of the present invention, when the person sitting on the seat 30 leans back against the seat back 20, the left and right sides of the seat back frame portion 21 can be adaptively wrapped around the occupant. The left and right sides thus enable the backrest portion 22 to support the spine and provide a positional support for the spine. By the shape and structure of the seat back 20, a person having extremely different body shapes can be comfortably supported while sitting on the seat 30.

According to the disclosure of the chair back structure of the present invention, the base 10 and the back frame portion 21 and the backrest portion 22 of the seat back 20 are integrally formed, and thereby reducing the number of parts, thereby facilitating assembly and reducing cost. Designed to reduce components and reduce assembly processes while saving manufacturing costs.

The above is only the preferred embodiments of the present invention, and is intended to be illustrative, and not restrictive, and it is understood by those of ordinary skill in the art that Many changes, modifications, and even equivalents may be made without departing from the scope of the invention.
