[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat formed by bonding a skin to a foam pad.

[0002]

2. Description of the Related Art A conventional automobile seat has a foam pad having a raised portion on the left and right with respect to the center of the upper surface and a concave groove in the front-rear direction of the upper surface, and is adhered to the upper surface of the pad. There is a body and a bag-shaped skin having a frame.

[0003] The skin in the above-mentioned conventional products uses a shrinkable fabric (for example, knit, knit).
This is because the skin can be adhered along the uneven upper surface of the pad without causing wrinkles and blemishes. A decorative pattern is formed on the surface of the sheet by providing a concave groove on the upper surface of the pad in the front-rear direction and biting and bonding a part of the skin into the concave groove. .

[0004]

Accordingly, an automobile sheet formed by bonding the skin to a pad having an uneven top surface is a non-excellent sheet having excellent appearance quality such as a moquette other than a skin having elasticity. There was a problem that the elastic skin could not be used. Therefore, an object of the present invention is to make it possible to use a non-stretchable skin.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a foam pad having a raised portion on the left and right sides with respect to the center of the upper surface and a concave groove in the front and rear direction of the upper surface. In a vehicle seat comprising a body bonded to the upper surface of the pad and a bag-shaped skin having a picture frame, a body or a frame of the skin corresponding to a center part in the front-rear direction of the groove is formed by a central part of the groove. A shrinking portion formed by shrinking the skin in the left-right direction is provided on the body or frame of the skin corresponding to the end side of the groove, and the shrunk portion is attached to the end of the groove. It is characterized in that it is adhered inside the part.

[0006]

The outer dimensions of the body or the frame are shortened due to the contraction. For this reason, the size of the area to be sewn to the terminal is substantially the same as that of the area, and no wrinkles or bulges are generated on the body or the frame side of the frame. Further, the contracted portion provided on the frame of the body is adhered in the concave groove of the pad and is not exposed to the outside.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an automobile seat according to the structure of the present invention, in which (SC) is a seat cushion, (1) is a skin made of a non-stretchable fabric such as a moquette, and (2) is a pad made of foam. , (3) indicates a frame, and (4) indicates a spring material for supporting the pad (2). On the seating surface of the seat cushion (SC), decorative patterns (a), (a), and (a) are formed in the front-rear direction, and the left and right patterns (a) and (a) are provided in a curved shape.

In the pattern (a), a part of the skin (1) is bitten into the grooves (201) and (202) provided on the upper surface of the pad (2) molded into a substantially seat cushion outer shape. It is formed by bonding. As shown in FIG. 4, the skin (1) has the upper surface (2) of the pad (2).
2) It is sewn in a bag shape so as to cover (21) and the side surface (23).

As shown in FIG. 4, the pad (2) has a concave groove (202) along a boundary between a central portion (21) (21) of the upper surface and raised portions (22) (22) provided on the left and right sides thereof. ) (2
02), and a concave groove (201) is formed in the center part (21) in the front-rear direction. Each of these grooves (20
1) (202) is molded with the same groove width and the same depth as a whole. (23) in the figure is the side surface of the pad (2).

The illustrated skin (1) has a body (11) covering a central portion (21) (21) of the pad (2), and a raised portion (22) of the pad (2) integrated with the body (11). )
The frame (12) covering the (22) and the body (1)
A town (1) covering the side surface (23) of the pad (2) by sewing together before and after 1) and on the left and right sides of the picture frames (12) and (12).
3).

A contraction portion (A) formed by contracting a part of the skin in the left-right direction is formed on the front side or the front side and the rear side of the body (11) and the frame (12) of the above-mentioned skin (1).
(A) (A) is provided. Each of the contracted portions (A) is formed in a portion corresponding to the end of the concave groove (201) (202) of the pad (2).

As shown in FIG. 5, the contracted portion (A) is provided with a part of the epidermis (1) by pinch or stitch sewing, or as shown in FIG. 6, the body (11) of the epidermis (1). ), Notches (A ′), (A ′) and (A ′) are provided in advance in the frames (12) and (12), and the notches (A ′)
The left and right edges are stitched or joined together.

Due to the contracted portion (A), the dimensions of the outer peripheral surface of the body (11) and the frame (12) of the skin (1) are as follows:
Since the size of the town (13) to be sewn to the outer peripheral surface is the same as the size of the town (13), the body (1
1) When the picture frame (12) is joined, no wrinkles or bulges are formed at the joining portion between the two.

The above-mentioned skin (1) has its body (11), frames (12) and (12) pressed on the entire upper surface of the pad (2) and bonded with an adhesive, and the end of the town (13) is a hog ring. Then, the sheet is formed by binding to a trim wire or the like provided on the frame (3).

The body (11) and the frame (12) (1)
When bonding 2) to the pad (2), the center of the body (1) is inserted into the groove (201) of the pad (2), and the body (11) and the frame (12) are inserted into the groove (202). ) Adhesion is made by biting the portion along the boundary of (12). And since the said contraction part (A) is located in the edge part side of the part which bites into these groove | channels (201) and (202) and adheres, this contraction part (A) is formed by the groove | channel (201) ( 202). Thereby, the decorative patterns (a) shown in FIG. 1 are formed on the upper surface of the seat cushion (SC).

[0016]

According to the present invention, since a contraction portion is provided on the skin, a skin made of a non-stretchable fabric such as a moquette can be used. When adhered to a pad having a direction, no wrinkles or blemishes occur on the skin. Then, by adjusting the degree of contraction of the skin formed by the contracted portion in the left-right direction, the sheet can be adhered to a pad having a deep concave groove without wrinkles or bulges, and a sheet having excellent appearance quality can be provided.
