The skin material mounting construction includes a pair of fastening members (i.e., right and left side fastening members) mounted along the left and right side end portions of the skin material, respectively, and at least one connecting member for connecting the pair of fastening members to each other. In a state where each end of the skin material is located on the back surface of the seat base, the skin material covers the surface of the seat base by attaching a pair of fastening members and connecting the attached pair of fastening members to each other with a connecting member. Thus, the skin material is mounted in a low-cost, easy-to-handle and quality-stable manner.

As shown in fig. 3, the pair of fastening components includes a partially rigid first member 130 extending along the left and right side ends of the skin material, respectively, and a second member 140 attached to the first member 130. The first member 130 is made of a cloth material and a resin material injected onto the cloth material, and the cloth material and the skin material are sewn and fixed together. The second member 140 may be snapped onto the first member 130 at one or more mounting points. In one example, the second member 140 is removably snapped onto the first member 130. In fig. 3, three mounting points are shown, one on each of the left and right sides. More mounting points may be provided as needed to help provide a multi-point secure attachment. The left second member 140 and the right corresponding second member 140 may be connected to each other by a connection member 200.

Figures 4 and 5 show perspective and plan views, respectively, of an enlarged detail of the part identified by a in figure 3; FIG. 6 shows a perspective view of a first member of the fastening component; fig. 7 and 8 show a perspective view and a plan view, respectively, of a first embodiment of a second member of the fastening component. Referring to fig. 6, the first member 130 is an elongated molding member extending longitudinally along the left and right side ends of the skin material. The first member 30 has rigidity in the left-right direction as indicated by arrow a (i.e., the direction in which the first member and the second member are attached) to avoid bending, thereby making the tension at the skin material uniform to ensure the appearance quality of the skin material is stable; and may not have rigidity in the front-back direction as indicated by arrow B because there is no tension. The first member 130 includes an attachment portion 132 molded with the cloth material and a snap-in portion 136 to be received by the second member 140. The shape of the first member 130 is not limited to the shape shown in fig. 6, and may have other shapes having similar functions.

Referring to fig. 7 and 8, in one example, the second member 140 includes a receiving portion 150 for receiving the snap portion 136 of the first member 130 and a hooking portion 160 for hooking the connection part 200. The receiving portion 150 of the second member 140 is made of a material having suitable elasticity, and the inner space enclosed by the receiving portion 150 is adapted to the contour of the clamping portion 136 of the first member 130, so that the receiving portion 150 can easily clamp the clamping portion 136 and can be firmly held on the clamping portion 136. A reinforcement part 170 may be provided at a suitable position of the receiving part 150, and the catching part 136 may be provided with a recess, the reinforcement part 170 and the recess cooperating, thus preventing the second member from sliding against the first member. An escape prevention portion 180 may be provided at a proper position of the hooking portion 160 to prevent the connection part 200 from escaping from the second member 140.

The second member 140 shown in fig. 7 and 8 is a bilaterally symmetrical structure, and thus includes two symmetrical hooking portions 160 (i.e., in an installed state, the hooking portions include an inner hooking portion and an outer hooking portion), so that the attachment 200 can be selectively hooked on either of the hooking portions 160. Also, when the receiving portion 150 of the second member 140 is attached to the catching portion 136 of the first member 130, the attachment is directly performed without considering the installation direction of the second member.

The connection member 200 may be a string-shaped member. As shown in fig. 3, the string-shaped members may be loop-shaped string-shaped members that hook the hooking portions 160 of the second members 140 of the pair of fastening parts, respectively. At the time of attachment, it is preferable that the looped string-like member is twisted at the middle portion at least one turn (one turn as shown in fig. 3), and then the looped end portions of the left and right sides respectively catch the corresponding hook portions 160 of the second members of the pair of fastening parts, thereby making the looped string-like member less likely to be disconnected. There are several alternative ways of attachment when the looped cord-like member is attached to the hook portion 160 shown in fig. 7 and 8. For example, the looped string-like member may be hooked on the inner hook portion of the second member on both left and right sides to prevent the looped string-like member from being dropped by an unintended collision. Alternatively, a looped string-like member may be hooked on the outer side hook portion of the second member on both left and right sides to facilitate the attaching operation. Alternatively, the looped string-like member may be hooked on the inner side hooking portion on one side and the outer side hooking portion on the other side of the left and right sides, thereby both preventing the looped string-like member from being dropped by an unintentional collision and relatively facilitating the attaching operation.

The attachment member 200 may be a cord-like member (not shown) having loops only at both ends, the opening of the loop being adjustable in size to fit snugly over the corresponding hook portion 160 of the second member of the pair of fastening components.

In addition, the connection member 200 may be provided with a length adjustment portion to adjust the connection tightness of the skin material as needed. The rope-like member is readily available on the market and inexpensive.

Fig. 9(a) -9(c) show perspective views of other embodiments of the second member of the fastening part of the cover material fixing construction according to the present invention. In particular, these second members are characterized by an asymmetrical structure, having only a single hook portion 160. The second member having a single hook portion is not limited to the specific configuration shown in the figures, and other second members having a receiving portion and a hook portion are possible. When the second member shown in fig. 9(a) to 9(c) is to be engaged with the first member, it is necessary to determine the engagement direction of the second member according to the manner of connection with the connection part. For example, the individual hook portions of the second members of the pair of fastening components may each be disposed outwardly, inwardly, or one of outwardly and the other inwardly.

In mounting the skin material, the skin material is first fitted over the front surface of the seat base, then the left and right sides of the skin material, which have been extended to the back surface of the seat base, are sewn together with the cloth material of the first members 130 of the fastening parts (alternatively, this sewing step may be performed between the fitting steps), then at least one second member 140 of the fastening parts is respectively snapped onto the first members 130 of the pair of fastening parts at desired mounting points, then the respective second members 140 of the pair of fastening parts are connected to each other with the connecting parts, and optionally the length of the connecting parts is appropriately adjusted, so that the skin material can fit and firmly cover the front surface of the seat base, providing an aesthetically pleasing seat.

For CN103121417B, according to the utility model discloses a skin material fixed knot constructs, owing to only need set up fastening components in the left and right sides of seat base member and need not to set up fastening components in the upper and lower both sides of seat base member, has saved the material and has reduced the installation complexity. In addition, since the fastening member has rigidity and extends along the end portion of the skin material, and the tension of the end portion of the skin material is uniform, the skin material at the straight portion is not easily bent, so that the appearance quality is stable.

Compared with CN112004443A, according to the skin material fixing structure of the present invention, since it is not necessary to form the groove 2A in the seat base, the manufacturing cost can be saved; since the link member 200 does not need to be disposed in the groove 2A, it does not need to be operated in the groove, and it can be operated on the back surface side of the seat base body to make the attachment easier to operate; the operation is more convenient and simple because the pair of fastening parts are directly connected by the connecting part.
