Description of the Invention [Technical Field] The present invention relates to a chair having a mesh pad or a seat or a chair head. [Prior Art] More and more chair backs or seat or chair head mats are meshed, • that is, 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 tweezers, 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. The carrier and attachment method for load-bearing fabric is also to bond the mesh mat to a carrier and then fix the medium 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 having the seat with differential front and rear support portions secure the mesh mat to the frame. 5 I3604Q0 = The above-mentioned prior art has not shown that the mesh 塾 is directly fixed on one, and the frame includes a soft frame and a hard-soft frame and a hard-framed sheep 俨 μ φ 士 架 架...

The second frame includes a first frame and a second frame, and the first frame uses the material of the second frame. The reason is that the body that the frame is in contact with is therefore made of a soft material that makes the user feel comfortable. The sixth frame employs a relatively rigid material f such that the shape of the main frame is relatively strong and bears the weight of the user's body. The mesh pad of the mesh pad is placed at a position where the first frame and the second frame are joined or at an appropriate position of the first frame, or at an appropriate position of the second frame. When the first frame and the second frame are shot, i combines the mesh frames. Since the invention has novel construction, can provide industrial utilization, and has an improvement effect, it applies for an invention patent according to law. [Embodiment] Referring to Figure 1, the seat cushion 10 of the present invention may be a seat back 5 of a chair i, a seat 6 or a headrest 7. The seat cushion 1〇 mainly comprises a main frame 2〇 and a mesh pad 6 1360400 50. In addition, in the present specification, the mesh pad 50 means a cushion having a plurality of holes or a plurality of elongated groove-shaped holes, that is, a mesh pad. 50 series mats with good aeration 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 φ 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 frame 13 40 are integrally injection molded, and the mesh pad 50 of the mesh pad 50 is placed at the same time as the injection molding. The position between the joint surface 32 and the second joint surface 42 is such that when the first frame 30 and the second frame 40 are ejected, the mesh pad periphery 51 is joined to the main frame 20. Therefore, the mesh pad 5 can be secured not only to the main frame 20 but also with high manufacturing efficiency to reduce costs. Please refer to FIG. 3 regarding the second embodiment of the seat cushion 1A. The main difference between the second embodiment and the first embodiment is that the mesh dome 51 is fixed in the first frame 30. In the manufacture of the seat cushion 1a of the second embodiment, it is preferable that the first frame 3〇 and the second frame 40 are integrally injection-molded, and the mesh-like circumference of the mesh is formed at the same time as the injection molding. 51 is placed at the appropriate position of the first frame 3' so that when the first frame and the second frame 4 are ejected, the mesh pad periphery 51 is joined to the first frame 3A. 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 seat cushion 1b, it is preferred 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 second frame 40, when the first frame 3〇 and the second frame 4〇 are ejected, the mesh dome 51 and the second frame 4〇 are joined together. The effects of the above three embodiments are slightly different, and the description is as follows: The mesh pad periphery 51 of the mesh pad 5 of the seat pad 10a of the second embodiment is placed at an appropriate position of the first frame 30 because the first frame 3 is adopted. The softer material 'so the mesh 塾·50 can be deformed more when pressed. In the first embodiment and the third embodiment, the mesh 塾 5 承受 is directly received by the second frame 40 when pressed, so that the mesh pad 5 变形 is deformed less when pressed under the second embodiment. 8 1360400 It should also be noted that although FIGS. 2 to 4 are taken as an example of a sectional view of the seat back 5, the sectional view of the seat 6 or the headrest 7 is the same as that 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 merely for the purpose of illustration and description, and the scope of the invention is intended to be limited by the scope of the claims.
