Further, the front end portions of a plurality of third connecting members J3 extending in the front-rear direction are fixed (for example, sewn) to the upper and lower intermediate portions of the central base skin portion 25m, and these connecting members J3'... , respectively, and reach the rear surface of the back pad P2.

The locking pieces 27j and 27k provided at the rear end of the member main body Ja of the first to third connection members J1' to J3' for the seat back are basically used to lock the connection members J1 to J3 for the seat seat. A structure similar to that of the stoppers 17j and 17k can be applied. However, while the other pressure-receiving member was only the pan frame 11 in the seat portion S1, in the seat back portion S2, the pressure-receiving member was located at a position corresponding to each lead-in hole P2h of the back pad P2 (i.e., opposite to each lead-in hole P2h). The pressure receiving plate 24 and the wire 28 exist in the area or the vicinity thereof (hereinafter the same applies). Incidentally, if the wave spring 29 is disposed at a position corresponding to the retracting hole P2h of the back pad P2, the connecting members J1' to J3' may be locked and connected to the wave spring 29.

The pressure receiving plate 24 includes a substrate portion 24b formed generally flat along the back surface of the back pad P2, and left and right side plate portions 24s as inclined portions that rise forward and outward from both left and right sides of the substrate portion 24. It has both. The pressure receiving plate 24 is provided with through holes h1', h2' and a reinforcing bead 24bb similar to the through holes h1, h2 and reinforcing bead 11bb of the pan frame 11, and these through holes h1', h2' Of these, the locking pieces 27j and 27k of the connecting members J1' to J3' are locked and connected to the through holes h1' and h2' located at positions corresponding to the lead-in hole P2h of the back pad P2.

The locking and connecting structure of these locking pieces 27j and 27k to the pressure receiving plate 24 is similar to the locking and connecting structure of the locking pieces 17j and 17k of the seat connection members J1 to J3 described above to the pan frame 11. It is similar to For example, in FIG. 6(A), the hook-shaped locking piece 27j of the first connecting member J1' is locked and connected to the through hole h2' provided in the side plate part 24s as the inclined part of the pressure receiving plate 24. An example is shown, but instead of/in addition to this locking piece 27j, for example, a clip-shaped locking piece 27k (not shown) is used in the same locking manner as the locking piece 17k in FIG. 7(B). , may be fitted and locked into the through holes h1' and h2' of the pressure receiving plate 24.

Further, FIG. 6(B) shows an example in which the hook-shaped locking piece 27j of the first connecting member J1' is locked and connected to the wire 28.

The locking pieces 27j and 27k of the seat back connecting members J1' to J3' may be hooks or clips, similar to the locking pieces 17j and 17k of the seat seat connecting members J1 to J3. Alternatively, it may be of any other suitable shape, but especially when the opposing pressure receiving member is the wave spring 29 or the wire 28, locking is facilitated by using the hook-shaped locking piece 27j.

Furthermore, the base skin 25 and the easily removable skin 26 in the seat back portion S2 are removably connected by first to fourth fasteners f1' to f4' for the seat back. These fasteners f1' to f4' have basically the same structure as the above-mentioned first to fourth fasteners f1 to f4 for the seat portion, which connect the base skin 15 and the easily removable skin 16 in the seat portion S1. Therefore, further explanation will be omitted.

In the seat back portion S2 of this embodiment, the pressure receiving plate 24 and the wire 28 are installed on the back frame F2 to support the back pad P2, and are an example of the pressure receiving member of the present invention. Further, the back pad P2 is an example of a pad of the present invention, and the back frame F2 is an example of a frame of the present invention.

Next, the operation of the first embodiment will be explained. Regarding the base skin 15 of the seat skin C1, the outer circumferential base skin part 15z, the center base skin part 15m, and the left and right base skin parts 15s are sewn together, and the first to A base skin unit is made in advance by sewing the third connecting members J1 to J3 and the inner fastener pieces f1i to f4i of the first to fourth fasteners f1 to f4, and the base skin unit is attached to the seat pad P1. Place it so that it covers the top.

From this state, part of the skin of the base skin unit is pulled into the first to third retraction grooves g1 to g3 on the upper surface of the seat pad P1, respectively. Then, the first to third connecting members J1 to J3 connected to each retractable portion are extended to the back side of the seat pad P1 through the retracting hole P1h, and the locking pieces 17j and 17k at the extending ends are connected to the pan frame 11. It is locked and connected to the through holes h1 and h2 existing at the position corresponding to the lead-in hole P1h.

After that, the outer periphery of the lower half of the outer periphery base skin part 15z of the base skin unit described above is fixed (for example, glued) to the left and right side frames 10 so as to wrap around the lower surface thereof, and the front of the seat pad main body P1m is , and fixed (for example, by gluing) to the rear end portions so as to wrap around their lower surfaces.

In this way, the base skin unit including the base skin parts 15m, 15s, and 15z of the base skin 15 is fixed to the seat pad P1 so as to cover it. In this case, the state in which a part of the base skin 15 is drawn into the first to third retraction grooves g1 to g3 is maintained by the connecting members J1 to J3 being locked and connected to the pan frame 11. , it is possible to effectively prevent the occurrence of misalignment, loosening, wrinkles, etc. in the base skin 15 due to long-term use.

On the other hand, the easily removable skin 16 of the seat skin C1 is sewn between the center easily removable skin part 16m and the left and right easily removable skin parts 16s, and the An easily removable skin unit is prepared in advance by sewing the outer fastener pieces f1o to f4o of the fasteners f1 to f4, and the easily removable skin unit is placed over the base skin 15 previously fixed to the seat pad P1. Place it like this.

From this state, by sequentially connecting the outer fastener pieces f1o to f3o and the inner fastener pieces f1i to f3i of the first to third fasteners f1 to f3, a part of the easily removable skin 16 is connected to the first to third retraction grooves. Pull into each of g1 to g3. After that, by connecting the outer fastener piece f4 and the inner fastener piece f4i of the fourth fastener f4, the easily removable skin 16 can be connected and fixed to the base skin 15. In addition, when removing the easily removable skin 16 from this state, the procedure is reversed to that described above.

Thus, attachment of the seat skin C1 to the seat pad P1 is completed. Also, when attaching the base skin 25 and the easily removable skin 26 of the seat back skin C2 to the back pad P2, the installation work can be performed using the same installation procedure as for the seat skin C1 described above.

In the seat portion S1 and the seat back portion S2 having the above structure, the easily attachable and removable skins 16 and 26 are attached to the base skins 15 and 25 fixed to the seat pad P1 and the back pad P2, respectively, using fasteners f1 to f4, f1' to f4' allows it to be easily attached and detached at any time. For this reason, the easily removable skins 16, 26 may be replaced with other easily removable skins 16, 26 with different colors, patterns, textures, etc. depending on the season, or the dirty easily removable skins 16, 26 may be removed and cleaned. It is possible and convenient.

In the present embodiment, a pan frame 11, a pressure receiving plate 24, and a wire 28, which serve as pressure receiving members that support the seat pad P1 and back pad P2, respectively, are installed on the seat frame F1 and the back frame F2. In particular, in the seat portion S1, a connection member in which a retracted portion of the skin C1 (more specifically, the base skin 15) into each of the retraction grooves g1 to g3 of the seat pad P1 passes through the retraction hole P1h. It is locked and connected to the pan frame 11 via J1 to J3. As a result, the connecting members J1 to J3 can be easily connected to the pan frame 11, which is located closer to the lead-in hole P1h than the seat frame F1, and the connecting members J1 to J3 are made smaller and lighter and have a simpler structure. is achieved, and the weight and cost of the seat portion S1 can be reduced accordingly.

On the other hand, in the seat back portion S2, a connection member in which a portion of the skin C2 (more specifically, the base skin 25) that is retracted into each of the retraction grooves g1' to g3' of the back pad P2 passes through the retraction hole P2h. It is locked and connected to the pressure receiving plate 24 and the wire 28 via J1' to J3'. As a result, the connecting members J1' to J3' can be easily connected to the pressure receiving plate 24 and the wire 28 which are located closer to the lead-in hole P2h than the back frame F2, and the connecting members J1' to J3' can be made smaller.
