Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention covers an automobile seat (seat), more specifically, a seating surface side of a foam pad, a vertical groove for decoration, and a horizontal groove whose end is connected to the vertical groove to cover the pad. The present invention relates to a seat formed by adhering a surface skin to a seating surface of a pad and forming a groove pattern for decoration on the seating surface of the seat.

[0002]

[Prior art]

 FIG. 4 shows a seat back (SB) and a seat cushion (SC) in a conventional seat of this type. In the figure, (10) is a decorative groove-shaped lateral pattern provided on the seating surface of the seat, (20). ) (20) show the same vertical pattern, and wrinkles (a) ... which impair the appearance quality of the sheet are generated on the vertical pattern (20) side of the horizontal pattern (10).

FIG. 5 shows a pad (P) before covering the seat back (SB) and seat cushion (SC) shown in FIG. 4 with a non-stretchable skin such as moquette and adhering the skin, Horizontal grooves (1) and vertical grooves (2) and (2) are formed at the same depths at locations corresponding to the horizontal patterns (10) and vertical patterns (20). (2) The horizontal pattern (10) and the vertical patterns (20) and (20) are formed by pressing and adhering the epidermis to the (2). In the figure, (30) indicates a central portion of the seating surface, and (31) and (31) indicate raised portions on the left and right sides of the central portion (30), respectively. The above wrinkles (a) occur when the epidermis is adhered to the pad (P) on the epidermis adhered to the end of the lateral groove (1) on the longitudinal groove (2) side.

[0004]

[Problems to be solved by the device]

 Then, this invention aims at removing the inconvenience of the said conventional product in the sheet | seat which adheres such a non-stretchable outer_skin to a pad, and forms the groove-shaped pattern for decoration on the surface.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is directed to a sheet in which a skin is adhered to a pad having a lateral groove and a vertical groove on the seating surface, and the depth of the lateral groove provided in the pad is measured in the end direction. It is formed gradually shallower.

[0006]

[Action]

 A non-stretchable skin is coated on the seating surface side of a pad having vertical and horizontal grooves on the seating surface, and a part of the skin is inserted into the vertical and horizontal grooves and bonded to obtain a horizontal pattern and vertical pattern. As a result, wrinkles do not occur on the vertical pattern side of the horizontal pattern.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 show a pad (P) used in the present invention. FIG. 1 is a portion of the pad (P) shown in FIG. 5 taken along the line AA, and FIG. 2 is taken along the line BB. Sectional views of each part are shown. As usual, the pad (P) is molded with a foamed material such as urethane foam, and at the time of molding, the lateral groove (1) and the vertical groove (2) are simultaneously molded.

The horizontal groove (1) and the vertical groove (2) are provided at the positions shown in FIG. 5 in the pad (P), and the entire vertical groove (2) is formed to the same depth as in the conventional case. It is provided along the boundary between the central portion (30) and the raised portion (31). The lateral groove (1) is provided so as to extend between the left and right vertical grooves (2) and (2).

As shown in FIGS. 1 and 2, the lateral groove (1) is formed such that the end portion (11) on the vertical groove (2) side is gradually shallowed toward the vertical groove (2). The part in contact with (2) is formed so as not to have the same groove shape as the surface of the central part (30). The central portion (30) of the pad (P) is formed in a concave and convex shape in the left-right direction. In FIG. 1, (41) in the figure shows a frame for supporting the pad (P), and (42) shows a supporting member made of the same spring.

FIG. 3 shows a part of the sheet formed by adhering the skins (3A) and (3B) to the above pad (P). The skin (3A) is inserted into the lateral groove (1) and adhered. . Then, the joint points of the outer skins (3A) and (3B) are inserted into the vertical grooves (2) and adhered, and the ends of the outer skin (3B) are provided on the frame (41) side with a hog ring or the like. It is integrally attached to the trim wire.

The above skin (3A) is a non-stretchable cloth such as moquette that is not sewn together, and has the same width in the direction orthogonal to the lateral groove (1). That is, a skin (3A) having the same width is used for the adhesive portion at the end (11) of the lateral groove (1) and the portion for adhering to the central portion of the lateral groove (1) in the groove direction. The part bonded to the part (11) side is not processed to be wide.

[0012]

[Effect of device]

 According to the present invention, since the depth of the lateral groove provided on the seating surface of the pad is gradually reduced toward the end portion, a part of the epidermis is inserted into the lateral groove and the longitudinal groove of the pad to attach the epidermis to the pad. When adhered to the seating surface of the pad, the skin adhered to the end of the lateral groove of the pad is pulled to the skin adhered to the longitudinal groove of the pad.

However, the end portion of the lateral groove of the pad is formed to be gradually shallower in the vertical groove direction. Therefore, since the outer skin bonded to the end of the lateral groove has a margin, the pad on the peripheral side of the end of the lateral groove is not crushed by the outer skin. That is, since it is not pulled by the skin adhered in the vertical groove, wrinkles and tarmi that deteriorate the appearance quality of the sheet do not occur in the portion corresponding to the end of the horizontal groove in the pad unlike the conventional product shown in FIG. .
