Description of the Invention [Technical Field] The present invention relates to a chair having a mesh pad or a seat or a headrest. [Prior Art] More and more chair backs or seat or chair heads use mesh mats, which include mats with multiple holes or a plurality of long slotted holes, because the mesh mat has ventilation effect. In addition, the mesh mat can provide appropriate flexibility without the need for thick mats, so there is also the concept of environmental protection. The structure in which the mesh pad is fixed to the frame is very important because it involves the firmness of the mesh pad, manufacturing efficiency, and the like. U.S. Patent No. 6,588,842 (Backrest) incorporates a mesh-like crucible into a one-piece carrier member and secures the vehicle to the frame. Car US Patent No. 7096549 (Carrier and attachment method for load-bearing fabric) also bonds the mesh mat to a carrier » and then fixes the vehicle to the frame. US Patent No. 6,957,861 (Structure of a mesh back of a chair) sandwiches a mesh mat on two frames. U.S. Patent No. 6,439, 665 (Ergonomic chair with mesh seat and back)' and US korea No. 6254190 (Chair having a seat with differential front and rear support portions) secures the mesh raft to the frame. 5 201000051 However, the above-mentioned various techniques have not shown that the mesh potential is directly fixed to a frame, and the frame includes a soft frame and a hard frame, and there is no integral body = frame and hard frame forming, and _ also _ pad combination The present invention is directed to providing a mesh mat that can be secured to the main frame and that increases manufacturing throughput. Dry uy, Wang Hui ❹ ❹ In order to achieve the above object, the seat cushion of the present invention comprises a 塾 塾 and the seat cushion can be a back, a seat or a chair 塾. The main material of the net is: (2) mining: to the weight: the shape of the winning frame _ net = the mesh around the first frame and the second frame combined with the position $ ^ a proper position of the frame, or the second frame The right place. In the case of the first (fourth) and the second frame, and the surrounding area of the mesh and the main body, the present invention is novel in construction, can provide industrial use, and does have an improvement effect, so the invention patent is applied according to law. [Embodiment] Referring to FIG. 1 , the seat cushion 1 of the present invention may be a chair back 5, a seat 6 or a seat cushion 7 . The seat cushion 10 mainly includes a main frame 2 〇 and a mesh pad 6 . 201000051 50, additionally, in the present specification, the meaning of the mesh pad 50 includes a mat having a plurality of holes or a plurality of elongated slot-shaped holes, that is, the mesh pad 50 is a mat having a good ventilation effect. There are three preferred embodiments in the following, which are respectively shown in Fig. 2, Fig. 3 and Fig. 4. Please refer to Fig. 1 below. Please refer to FIG. 2 for the first embodiment below. The main frame 20 includes a first frame 30 and a second frame 40, and the material of the first frame 30 is softer than the material of the second frame 40. The first frame 30 includes a first outer side surface 31 and a first joint surface 32. The first frame 30 is made of a soft material because the first outer side surface 31 of the first frame 30 contacts the user's body. The soft material makes the user feel comfortable. The material of the first frame 30 is, for example, a soft thermoplastic elastomer such as thermoplastic rubber or polyurethane. The second frame 40 includes a second outer side surface 41 and a second joint surface 42. The second frame 40 is harder than the material of the first frame 30, so that the shape of the entire main frame 20 is relatively fixed and can withstand The weight of the user's body. The material of the second frame 40 is, for example, a relatively hard plastic such as polypropylene, polyamide or a composite material thereof. The mesh pad 50 includes a mesh pad perimeter 51 that is coupled to the main frame 20, as shown in FIG. 2. In the first embodiment, the mesh pad perimeter 51 is located on the first bonding surface 32 and Between the second joint faces 42. Further, the first joint surface 32 and the second joint surface 42 are in a coupled state, and the first joint surface 32 and the second joint surface 42 are substantially all smooth surfaces such as a flat surface or a curved surface. In the manufacture of the seat cushion 10, it is preferred that the first frame 30 and the second 7 201000051 frame 40 are integrally injection molded, and the mesh pad periphery 51 of the mesh pad 50 is placed on the first joint surface while being injection molded. The position between the 32 and the second joint faces 42 is such that when the first frame 3〇 and the second frame 4〇 are ejected, the mesh pad periphery 51 is joined to the main frame 2〇. Therefore, the mesh pad 5 can be secured not only to the main frame 20 but also with high manufacturing efficiency to reduce costs. Referring to Figure 3, the second embodiment of the seat cushion 1A is shown. The main difference between the second embodiment and the first embodiment is that the mesh pad periphery 51 is fixed in the first frame 30. In the manufacture of the second embodiment of the seat cushion 1A, it is preferable that the first frame 30 and the second frame 40 are integrally injection molded, and the mesh pad periphery 51 of the mesh pad 50 is placed at the same time as the injection molding. At the appropriate position of the first frame 3', when the first frame 3'' and the second frame 40 are ejected, the mesh pad periphery 51 is joined to the first frame 3''. Please refer to FIG. 4 regarding the seat cushion 1b of the third embodiment. The main difference between the third embodiment and the first embodiment is that the mesh pad periphery 51 is fixed in the second frame 40. In the manufacture of the second embodiment of the chair frame 1b, it is preferable that the first frame 30 and the second frame 4 are integrally formed by injection molding, and the mesh pad periphery 51 of the mesh pad 50 is formed while the injection port is formed. Positioned in the appropriate position of the second frame 40, so when the first frame 30 and the second frame 40 are ejected, the mesh pad periphery 51 is joined to the second frame 40. The effects of the above three embodiments are slightly different, as explained below: The mesh pad periphery 51 of the mesh pad 50 of the seat cushion 10a of the second embodiment is placed at an appropriate position of the first frame 30 because the first frame 30 is soft. The material is so that the mesh pad 50 can be deformed when pressed. In the first embodiment and the third embodiment, the mesh pad 50 is directly received by the second frame 40 when pressed, so that the mesh pad 50 is deformed less when pressed under the second embodiment. 8 201000051 It should be noted that FIGS. 2 to 4 are taken as a cross-sectional view of the seat back 5, but the sectional view of the seat 6 or the headrest 7 is the same as the sectional view of the seat back 5. To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examinations and grant the patents as soon as possible. It is to be noted that the various embodiments described above are intended to be illustrative only, and the scope of the invention is intended to be limited by the scope of the appended claims.
