Abstract

(57) [Abstract] [Purpose] To prevent peeling of a cushioned body with a skin from a terminal in a seat from a blow-molded frame and a cushioned body with a skin fixed to the frame. [Structure] Blow-molded frame (1) with skin (3)
It is characterized in that a substantially V-shaped fitting groove (11) for fitting the end (21) of the attached cushion body (2) is formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a structure of a synthetic resin frame integrated type seat for automobile seats (seats), and more specifically, it is made of foam with a skin that is integrally fixed to a hollow frame formed by blow molding into a substantially sheet outer shape. The present invention relates to a fixing structure of a cushion body to a terminal frame.

[0002]

[Prior art]

 In order to reduce the weight of conventional seats, there is a sheet that uses a hollow frame molded by blow molding and has a cushion cushion made of foam laminated to the seating surface side of this frame. The cushion body and the foam cushion body with skin are fixed to the hollow synthetic resin frame in this seat by using a velvet fastener for the cushion body and the frame.

[0003]

[Problems to be solved by the device]

 By the way, in this conventional seat, the integrity of the pair of cushions with skin on the frame is poor, and the cushion with skin may be peeled from the end of the seat. There was a defect that could not be retained. Then, this invention aims at eliminating the malfunction in such a conventional product.

[0004]

[Means for Solving the Problems]

 According to the present invention for achieving the above object, a substantially V-shaped fitting groove is provided in an annular shape along the periphery of a seating surface of a blow-molded frame, and the cushion with skin is provided in the fitting groove. It is characterized in that the terminal of the body is engaged. It is desirable that the above cushion body with skin be integrally bonded in the blow mold during blow molding.

[0005]

Since the end of the cushioned body with the skin is engaged in the substantially V-shaped fitting groove of the frame, it does not project beyond the surface of the frame and the body of the seated person is not caught.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a seat according to the present invention, in which a seat back and a seat cushion (SC) are integrally molded by a synthetic resin frame (1), and a seating surface of the frame (1) is covered with a skin. (3) Attached cushion body (2) is integrally fixed. In the figure, (L) shows a leg attached to the frame (1).

The structure of this sheet will be described with reference to FIGS. 2 to 4. The frame (1) is a blow molding type and is blow molded into a substantially seat (seat back and seat cushion integrated type) outer shape. At that time, the molding die is provided with a projection at a portion corresponding to the end of the cushion body (2) with the skin (3), and a substantially V-shaped fitting groove (11) is formed in the frame (1). To do so. Therefore, the fitting groove (11) is formed in a ring shape along the periphery of the cushioned body (2) with the skin (3). The frame (1) is formed in a hollow shape except for a connecting portion of the seat back (SB) and the seat cushion (SC).

The cushion body (2) with a skin (3) is a urethane foam slab material obtained by laminating a skin made of a synthetic resin film on the surface or adhering a skin such as a woven fabric to the surface. When the frame (1) is blow-molded, the cushion body (2) is housed in a blow mold and fixed integrally with the frame (1). At that time, the cushion body (2) with the skin (3) is joined to the projection of the blow mold. Therefore, after blow molding, the end (21) of the cushion (2) with the skin (3) is fixed to the frame (1) while being engaged in the fitting groove (11) of the frame (1). . In the illustrated example, the cushion body with skin is fixed to the frame as a unit during molding of the frame, but the cushion body with skin may be bonded to the frame with an adhesive after the frame is molded.

Thus, the cushion body (2) with the skin (3) has the entire back surface integrally fixed to the frame (1), and the terminal (21) has the fitting groove (11) of the frame (1). ) Inside and does not protrude from the seating surface of the frame (1).

[0010]

[Effect of device]

 According to the present invention, since the end of the cushion body with skin is engaged in the substantially V-shaped fitting groove provided in the frame, the end of the cushion body with skin does not protrude from the seating surface of the frame. Therefore, since the terminal of the cushioned body with the skin is not scratched by the body of the seated person, it is not peeled off from the terminal, and the terminal is not visible from the outside, so that the appearance quality is improved.
