Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to seats for automobiles, etc., and particularly relates to a cushion pad, a frame supporting the cushion pad, and a surface of the cushion pad. It pertains to a sheet consisting of a surface material that covers the

(Prior art and problems to be solved by the invention) Conventionally, this type of seat has a cushion pad made of a foam such as urethane, a surface material that covers the surface and side surfaces of the cushion pad, and a support for the cushion pad. It was equipped with a frame. The cushion pad, surface material, and frame were formed and assembled to constitute the sea ZOa as shown in FIGS. 1a to 1f. That is, as shown in FIG. 1a, the surface material 9 covers the top plate center part 1 and the top plate side parts 3 forming the seat surface of the seat, as well as the side parts of the cushion pad 7, and is latched to the frame. It has a gusset 5. Furthermore, a hanging bag 6 is sewn to the back surface of the central portion 1 of the top plate. The center part 1 of the top plate and the side parts 3 of the top plate are quilted with a pad 2 provided on the back side of the cloth 1a, as shown in FIG. 1b. Furthermore, the top plate center portion 1, top plate side portions 3, and gusset 5 are sewn together via the beaded edge 4, and the surface material 9 is formed as shown in FIG. 1C.

The cushion pad 7 is made of a foam such as urethane, and a wire 8 is insert molded into the foam (Fig. 1d).
. To assemble the surface material 9 to the cushion pad 7, the surface material 9 is turned over and the hanging bag 6 is secured to the wire 8 with a ring.

Thereafter, the surface material 9 was returned to its original position so as to cover the cushion pad 7, and the lower end of the gusset 5 was secured to a wire (not shown) of the seat frame with a ring (FIG. 1f).

For this reason, the surface layer material 9 was formed by cutting the central portion 1 of the top plate into a predetermined shape in advance, and then sewing it. Moreover, the surface material 9 had to be turned over once and assembled to the cushion pad, resulting in extremely poor workability.

Therefore, the technical objective of the present invention is to facilitate the assembly of the surface layer material.

[Structure of the invention]

(Means for Solving the Problems) The measures taken to solve the above problems are to hold the sides of the cushion pads by erecting side walls around the frame that supports the cushion pads, and to hold the sides of the cushion pads. A flange portion is formed extending outward from the flange portion, and the peripheral edge of the surface material is secured to the flange portion with a bead-like clip.

(Function) As a result, the surface layer material takes on a substantially planar shape and becomes easier to handle. Moreover, attachment of the surface layer material to the cushion pad is completed simply by locking the peripheral edge of the surface layer material to the flange portion of the seat frame using a bead-shaped clip. Therefore, even an unskilled worker can easily attach the surface material to the cushion pad.

(Example) An embodiment of the present invention will be described below based on the drawings.

The automobile seat illustrated in FIG. 2 includes a seat cushion 10 and a seat back 11.
・Cover 13 covering 12. and 12.
and. Seat cushion 10 which is the main part of the present invention
In addition, the seat hack 11 is configured as follows. Note that since the seat cushion 10 and the seat back 11 have substantially similar configurations, the following description will be based on the seat cushion 10.

As shown in FIGS. 3 to 7, the seat cushion 10 includes a top plate (surface material) 16, a cushion pad 18, and a seat frame 19. A flat pad 7 is provided on the lower surface of the top plate 16, and the top plate 16 is fixed to the cushion pad 18 at a band-shaped portion 26 by adhesive or high-frequency heat welding (see FIG. 4).

The seat frame 19 is made of synthetic resin and has a flat part 20 that supports the cushion pad 18 (FIG. 5).A side wall 21 is erected around the flat part 20 to hold the side part of the cushion pad 18. ing. A flange portion 22 extending outward is provided on the upper edge of the side wall 21, and
A protrusion 23 is formed on the lower surface of the flange portion 22 (
Figure 6). The peripheral edge of the top plate 16 is made of only a thin skin and covers the surface of the flange portion 22. A long beaded clip 24 having a C-shape is secured to the flange portion 22 through the skin of the periphery of the top plate 16 . Clip 24
has a meshing portion 25, and when the meshing portion 25 meshes with the protrusion 23, the clip 24 is securely fixed to the flange portion 22. Moreover, the periphery of the top plate 16 is the seat frame 1.
At the same time, the peripheral edge of the top plate is covered with the clip 24.

The seat cushion 10 is assembled as follows. That is, a top plate is fixed to the surface of the cushion pad 18,
After that, attach the cushion pad 18 to the seat frame 19.
(Figure 7).

The clip 24 is locked to the flange portion 22 via the outer skin of the periphery of the top plate 16. As a result, the assembly of the seat cushion 10 is easily completed (see FIGS. 6 and 7).

In the above embodiment, the surface material 16 is used as the cushion pad 1.
8 by welding or the like, but it may also be secured to the wire using a hanging bag. Alternatively, the surface layer 16 may be made of two members sewn together.

(Effect of the invention) As a means of easy assembly, it may be possible to fasten the top plate and the seat frame at the sides with a zipper, but the zipper may damage the clothes of the person sitting on the seat-H or cause injury to the human body. There is a risk that

However, according to the beaded clip of the present invention, the outer shape can be made into a soft and rounded shape, which has the advantage of not causing the above-mentioned problems.
