Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a vehicle seat such as an automobile.

[0002]

[Prior art]

 FIG. 5 is a partially cutaway perspective view of a conventional vehicle seat. As shown in FIG. 5, a seat 21 is composed of a seat cushion 22 and a seat back 23. In this seat cushion 22, a seat frame 24 that is a framework is formed. A seat pad 25 is provided surrounding the seat frame 25, and a trim cover 26 encloses the seat frame 24 and the seat pad 25. FIG. 6 shows this hooked state.

In FIG. 6, the four side ends 26 a of the trim cover 26 are folded back and sewn together, and the metallic wire 28 is housed in a long bag-like shape. A plurality of locking holes 24a are provided on the peripheral edge of the bottom surface of the seat frame 24 by cutting and raising a part of the frame 24, and the wire 28 of the terminal portion 26a and the locking holes 24a of the seat frame 24 are folded into the bottom surface side. The trim cover 26 was locked to the seat frame 24.

Further, FIG. 7 shows a sheet with improved holding performance in the prior art, and the same components as those in FIG. 6 are denoted by the same reference numerals.

A seat as shown in FIG. 7 is used in a sports type passenger car or the like, and a supporting member 33 is welded to a seat frame 24. By covering the supporting member 33 with a seat pad 34, The support portion 35a is formed on the side end portion of the seat cushion 35 so that it can be adapted to a complicated shape.

[0006]

However, in the above-mentioned conventional seat, the shape of the gusset portion is held by the seat pad and the trim end stopper, and therefore the frame structure must be changed depending on the shape of the seat pad. However, there is a problem in terms of cost, and in the sheet shown in Fig. 7, the shape of the seat pad is peculiar, so if the seat frame alone is used to stop the terminal or maintain the shape, the structure becomes complicated. There was a problem.

The present invention has been made in view of the above problems, and prevents the structure of the gusset portion from becoming complicated due to the shape of the seat pad, and changes the frame structure depending on the type of seat. It is an object of the present invention to provide a vehicle seat that does not require.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention places a cushion material on the upper part of a seat frame, encloses the seat frame and the cushion material with a skin material of a seat, and between the seat frame and the cushion material. It is characterized in that a shape-retaining plate is provided which is a base of the surface shape of the seat cushion and has a locking portion for locking the end portion of the skin material.

[0009]

[Action]

 Therefore, according to the present invention, since the surface shape of the seat cushion is formed by the shape maintaining plate and the cushion material, it is not necessary to match the structure of the seat frame with the shape of the cushion material, and the shape maintaining play is eliminated. The structure of the gusset portion can be simplified by hooking the skin material on the toe.

【Example】

 Hereinafter, a vehicle seat according to the present invention will be described with reference to FIGS. 1 is a partially broken perspective view of a vehicle seat according to the present invention, FIG. 2 is an exploded perspective view of the same, and FIG. 3 is a cross-sectional view taken along line 1A-A of FIG. 3, the vehicle seat 1 is composed of a seat back 2 and a seat cushion 3, and in this seat cushion 3, it is a skeleton of the seat cushion 3 and a joint member with a vehicle body (not shown). A shape-retaining plate 5 that serves as the shape of the seat cushion 3 is fixed to the seat frame 4 with fixing screws 6, and the shape-retaining plate 5 is covered with a seat pad 7 that is a cushioning material. The seat cushion 3 is constructed by surrounding the shape retaining plate 5 and the seat pad 7 with a trim cover 8 and attaching the ends to the shape retaining plate 5.

The seat frame 4 is a tray-shaped member, the upper end peripheral portion is folded back to the outside, and an abutting portion 4a for supporting the shape holding plate 5 is formed, and the rear portion of the bottom surface is joined to the body of the vehicle body. Is provided with a joint portion 4b, and a screw hole 4c for attaching the shape retaining plate 5 with the fixing screw 6 is provided in the front portion of the bottom surface.

A locking portion 5a that is folded back inward and locks the trim cover 8 is formed at the lower end of the shape-retaining plate 5, and the upper end has a shape suitable for the purpose of the seat. Hold portions 5b are formed, and screw holes 5c for fixing to the seat frame 4 are provided between the hold portions 5b, and a fixing screw 6 that penetrates the screw holes 5c is attached to the seat frame 4 The shape retaining plate 5 is fixed to the sheet frame 4 by being screwed into the side screw hole 4c.

The seat pad 7 is a flexible member such as urethane and has a shape corresponding to the shape retaining plate 5. The shape retaining plate 5 is surrounded by the seat pad 7, and the shape retaining plate 5 and the sheet The pad 7 is covered with the trim cover 8, the end portion of the trim cover 8 is folded into the locking portion 5a of the shape retaining plate 5, and then the locking portion 5a is crushed, so that the end portion of the trim cover 8 is crushed. The shape retaining plate 5 is engaged with the engaging portion 5a, and the sheet pad 7 is crimped to the shape retaining plate 5 by engaging both end portions of the trim cover 8, and the structure of the gusset portion 9 is also simplified. Has been transformed.

FIG. 4 shows a seat with improved side support according to the present invention. In such a vehicle seat 11, both side parts 13a of a seat cushion 13 are raised to form a seat. The surface shape of the cushion 13 is more complicated than that of the ordinary vehicle seat 1, but in the present invention, the shape can be changed by changing the shape of the hold portion 15a of the shape retaining plate 15, and the seat frame 4 can be used for ordinary vehicles. It uses the same one as Seat 1.

[0015]

[Effect of device]

 As described above, according to the present invention, since the surface shape of the seat cushion is formed by the shape retaining plate and the cushion material, it is not necessary to match the structure of the seat frame with the shape of the seat pad, and the structure of the seat frame is changed. It can be used for various types of seats without any problem, and by locking the trim cover to the shape retaining plate, the structure of the gusset part can be simplified and workability during seat manufacturing is improved.
