New type description: [Technical field of new type] This creation refers to the back plate of the kind, especially the back plate of the human body. [Prior Art] By pressing the user who is sitting on the seat for a long time, the back panel is usually additionally used as a support for the waist or the back to achieve long-term comfort. At present, there are many kinds of backplanes, which are mainly made of human spine scales. However, in order to increase the contact area of the back, the backboard usually only bends slightly and is slightly flat. When the human body is sideways or other curved parts. Abutting against the backboard 2, the backboard will only directly abut against the most protruding part, and affect the supporting effect and the comfort of the sin. H' and the force of the fork is concentrated in a specific area, and it is easy to cause the force part for a long time (4) Damage, therefore, the current backboard is only suitable for abutting against the back. If the user leans against other more curved parts, it will not be able to obtain a good branch effect and is likely to cause injury. [New content] In view of the above _, the main purpose of this creation is to provide a kind of backboard, in addition to the user to abut the back, when it is abutted at other parts, it also has a good branch effect to avoid Damage caused by uneven force. In order to achieve the above object, the present invention provides a back sheet comprising a body. The body of the sinus extends from the top toward the bottom with a predetermined curve, and the body extends longitudinally along the top and bottom to have a 镂 line, so that the human body can abut against the edge of the hollow portion, and the contact area of the abutment is increased. M429420 uses this to make the f-sulfur rely on the curved design of the body, which can provide the good (four) cutting effect of the back; the human body can be more convex when the other curved parts are like the side body against the body. The part is placed in the inner space, and the periphery of the part is used to abut against the edge of the hollow scent P to stagger the more convex part, thereby improving the supporting effect of the abutment, and increasing the contact area of the abutment, thereby avoiding The uneven power of the voyage, in order to make the financial (4) it meets the part of the song, 'can also obtain a stable support effect' has excellent comfort. [Embodiment] The following is a description of the structural features of the present invention and its intended success, which are not intended to limit the scope of the present invention. Please refer to FIG. 1 to FIG. 3, which is used for the human body to abut, and includes a body 1. The body 1 is preferably made of hard wood (other hard materials). The rigid body 1 has a top n and a bottom 12, and the top and bottom have different widths to facilitate the use of the body. As the identification function of the upper and lower placement positions. In detail, the bottom 12 width is slightly larger than the top u. When the profit body is placed longitudinally, the bottom portion 12 of the larger width provides a larger support area, so that the force received by the body is more dispersed. Moreover, the body 1 extends from the top U toward the bottom portion 12 in a predetermined curve, so that the body 1 is curved from the side, as shown in FIG. 3, and the body 1 extends longitudinally along the top and bottom to form an elliptical embodiment. The hollow portion 2' is provided for the human body to abut against the edge of the hollow portion 2, and the contact area is abutted; in the embodiment, the hollow portion 2 includes a first end 21 - the body V * - 4 M429420 end 22' the first end 21 and the second end 22 have a cross-sectional shape that is curved and the left and right sides of the hollow portion 2 are parallel to each other, and the top and bottom ends of the f portion 2 are slightly parallel to each other. The flat shape _, in line with the body's side chest, waist and body shape '咕 抵 抵 蚊 , , 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供 提供Or Shi Xi = enter the coating - green layer (such as foaming material " 7 ^ body to # hard material comfort. Better, soft layer outer surface material package S - through Lin (domain cloth, ΓΓ breathable effect , for a long time to make (four) wealth accounting __ no: 7, the real _ for the effect of massage, on the outer surface of the body 2 convex outward ^ also form the surface massage parts 3, each of the massage parts 3 into a semi-spherical shape (may also be /, 匕), and is disposed adjacent to the hollow portion 2, distributed around the hollow portion 2, for the user to directly abut the massage member 3 (as shown in Figure 4) to increase Massage area in the lower back, and each of the massage parts = Γ and facing different directions, relatively enhance the stimulation of the massage: spoon 2, choose whether to be covered by the recording layer or the breathable layer, if you choose ^,, The massage piece is not in disregard of the body, and the massage piece is hidden. The material of the wrong body is curved, and when the slightly curved part (such as the part) is pressed against the body, the supporting effect can be obtained. When used with a seat, as shown in Figure 5, the body can be placed on the seat in a slightly inclined manner, so that the body i Located between the back of the chair and the human body, the waist and hips of the human body are 5 P month b on the main body to improve the comfort of the ride. In addition, when changing the sitting position, the position angle of the body can be difficult. When the body 1 is placed on the seat at a relatively oblique angle, as shown in FIG. 6, the user can simultaneously abut the body and the seat in a rearwardly inclined posture. Adjust the position of the body according to the use condition, so that the user can obtain good support effect and comfortable comfort when correcting the angle. Monthly V refers to Figure 7 'When the user is more curved or vulnerable When the part (such as lying on the side) abuts against the backboard, the part 4 can be placed in the hollowed portion 2, and the part 4 is prevented from directly being pressed against the body, and the other relatively flat or recorded can be used instead. She leans on the edge of the body to cast 2 edges or other surfaces, which can increase the contact area of the abutment to avoid damage caused by uneven force and improve the overall support effect and the comfort of the abutment. It is mentioned that the curvature of the body is exactly the same as the back. The curvature of the back is extended, and the user can lean back (such as lying down) to abut the massage piece on the backboard, as shown in Fig. 8, to massage the specific part to achieve the effect of eliminating stiffness. In addition, the back can be stretched to relax the back, and has the effect of relaxing the muscles and promoting blood circulation, and also has the effect of stretching and relaxing while massage. To summarize the above, the back panel of the creation can be used by the user. A variety of postures, with a variety of use conditions, and can avoid the more fragile or protruding parts by the hollow part. In addition to avoiding the damage to the part, it can also enhance the effect of the choice of the abutment. The good comfort is really a progressive effect.
