Description

[Detailed description of the invention] (Industrial application field) This invention is applicable to vehicle seats such as automobiles,
More specifically, the present invention relates to a suspension structure for a skin member in a sheet having decorative grooves on its surface.

(Technology of conventional products and their problems) Conventional automobile seats have a hanging member sewn to the back side of a skin member that makes up the front surface of the seat, and this hanging member is sewn to the foam covered by the skin member. The skin member is suspended along the surface of the cushion material by being tied with a hogging ring to an insert wire embedded in the body cushion material, and decorative grooves are created on the seat surface by hanging with this suspension member. is forming.

By the way, this skin member is made by sewing the left and right edges of the body part to the frame part that forms the raised bank part.
Since the structure is such that the body part is suspended between the left and right seam parts, the hanging part of the skin member lifts up, causing wrinkles in the body part and the frame part that spoil the appearance of the sheet. In addition, in this structure, the suspension member provided on the back side of the skin member is pulled into the concave groove of the cushion material, and is tied to the insert wire etc. with a hogging ring, so there is a problem that the workability is significantly reduced. Ta.

(Means to Solve the Problems) Therefore, it is an object of the present invention to provide a sheet that has good assembly properties and has decorative deep grooves on its surface that improve the appearance of the sheet.

Therefore, the present invention connects only a part of the body part of the outer skin member to the frame part, but separates the other part, and connects the divided end of the frame part and the body part to a cushion that is divided corresponding to the outer skin member. They are inserted into the gaps between the materials and secured to a frame structure or the like.

Therefore, since the body part and the frame part of the skin member are hung independently, wrinkles do not occur in the body part and the frame part, and decorative objects can be used along the hanging part between the body part and the frame part. A deep groove is formed.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows an automobile seat according to the present invention,
The surface of the seat bag shown in A in the figure has decorative deep grooves a and a in the vertical direction, and the seating part b
Raised side support parts c, c are arranged on the left and right sides of the seat, and by operating the operating handle, these side support parts c, c rotate in opposite directions to hold the sides of the body of the seated person. It is composed of

Hereinafter, the present invention will be explained in detail based on FIGS. 2 to 7. In the figures, 1 is a skin member constituting the outer surface of the seat bag A, 2 is a cushion material made of a foam such as urethane foam, Central part 21
and an outer peripheral part 22 which is integrally connected to the upper end of the central part 21 and is covered with the frame part 12 and the gusset part 13 of the skin member 1. Further, numeral 3 in the figure is a frame structure that supports the cushion material 2 and fixes the end of the skin member 1.

The skin member 1 has a body part 1 as shown in FIG.
1, and a frame part 12 which has only the upper part of the body part 11 sewn together and has a gusset part 13 on its periphery, and the body part 11 has the frame parts 1 on its left and right sides.
2 and 12, and the end portions 11a and 11a are formed in a central portion 21 of the cushion material 2.
It is formed to a size that covers the side surfaces, and in the illustrated example, the terminals of both left and right end portions 11a, 11a are tied together with hogging rings, but these terminals are tied to the trim wires 36, 38 of the frame structure 3. Wearing it is also optional. Further, the lower end 17 of the body portion 11 is folded back and tied to the trim wire 35 of the frame structure 3 with a hogging ring. Bag-shaped hanging cloths 15, 15 with a core material inserted laterally inside are integrally sewn on the back side of the boundary between the body part 11 and the frame part 12 and on the back side of the body part 11. There is. And the frame part 12 of the skin member 1,
The ends of the ends 12a, 12a of the trim wires 12 are sewn to the trim wires 36, 38 of the frame structure 3, respectively, with hogging rings.

In the figure, 14, 14 are the ends 12 of the frame parts 12, 12
a, 12a to attach the central part 2 of the cushion material 2.
1. The cover pieces 14, 14 are used to prevent the frame structure 3 inside the seat back from being seen from the deep groove a. It is designed to prevent injury even if it is inserted by mistake.

Further, the gusset part 13, which is sewn integrally with the outer peripheral edge of the frame part 12 except for the lower part, covers the back surface from the outer peripheral surface of the outer peripheral part 22 of the cushion material 2, and the ends 13a, 13a are shown in FIG. Tie it to the trim wires 36 and 38 as shown, or attach it to the outer periphery 2.
It is fixed to the back side of 2. In addition, as shown in FIGS. 3 and 5, a hook 16 is sewn to the end of the upper gusset 13, and the member 33 of the frame structure 3
It is designed so that it can be hung on a.

As shown in FIG. 6, the cushion material 2 has a center portion 21 corresponding to the body portion 11 of the outer skin member 1 that is divided into right and left sides with respect to an outer peripheral portion 22, and only the upper portion thereof is foamed integrally with the outer peripheral portion 22. ing. and,
Insert wires 21a are buried vertically and laterally in this central portion 21, and a recessed groove (not shown) for hanging is carved on the surface of the central portion 21 along the insert wire 21a, and a recessed groove (not shown) for hanging is carved in this recessed groove. The skin member 1 is fixed by inserting the hanging cloth 15 of the skin member 1 and sewing the tip of the hanging cloth 15 together with the core material to the insert wire 21a with a hogging ring.

As shown in FIG. 7, the frame structure 3 has
Back frame 31 with a pipe bent into a substantially U-shape
Side frames 32, 32 constituting a side support device are rotatably arranged on the left and right sides of the back frame 31, and a reinforcing rod 34 is installed on the open end side of the back frame 31, and a trim wire 35 is fixed above the reinforcing rod 34. Furthermore, members 33a and 33b are installed on the upper and lower parts of the back frame 31, and
It has a structure in which trim wires 36, 37, 38 are welded vertically between the members 33, 40, and S springs 39, 39 are stretched across the trim wires 36. When the cushion member 2 is supported and the skin member 1 is fixed as described above, the seat bag A shown in FIGS. 2 and 3 is assembled.

Therefore, decorative deep grooves a, a are formed in the vertical direction between the seating part b of the seat back A and the side supports c, c, and the cushion material 2 has a central part 21 and side frames 32 on its left and right sides. Since the outer peripheral portions 22, 22 provided with the side support device are formed independently, the operability of the side support device is also improved. In the figure, 40 indicates a backboard.

(Effects) According to the present invention, the body part and the frame part of the skin member are separated from each other except for a part, and the cushion material corresponding to the divided parts of the body part and the frame part of the skin member are also divided in the same way. Because it is divided
A sheet having decorative deep grooves on its surface is assembled by fixing the divided ends of the body part and the frame part of the skin member to a frame structure or the like.
Therefore, since the body part and the frame part are attached separately, wrinkles that spoil the appearance of the sheet do not occur on the sheet surface, and the work of attaching the skin member is easy, and the ease of assembling the sheet is improved. In addition, since decorative deep grooves are formed on the sheet surface, the appearance of the sheet is improved and a sheet with excellent appearance quality can be provided.
