(57) [Abstract] [Purpose] To improve the shape retention of a pad of a vehicle seat without embedding it in the wire frame. [Structure] A cushion part (1) made of a molded product having raised portions on the left and right sides of a seating surface, and a frame part (2) made of a rigid foam integrally foamed in the same mold as the cushion part (1). ) And the shape retaining portions (22) and (22) are provided integrally with the frame portion (2).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention directly attaches to a vehicle body such as a foam pad for a vehicle seat such as an automobile seat (seat), specifically, a liya seat cushion (rear seat part), a liya seat back (rear seat back part), and the like. It relates to a pad in a supporting sheet.

[0002]

[Prior art]

 For this type of conventional liyaseat cushion and liyaseat back, a structure that supports the entire bottom surface or back surface of the seat on the vehicle body side has rigidity such as a frame made of sheet metal or a metal pipe. Instead, from the frame line and wire rods (straight line material, curved line material) arranged vertically and horizontally within the frame line in a pad made of foam (for example, urethane foam) that is molded into the outline shape of the sheet The wire frame made of is buried.

[0003] The liya seat cushion is formed by covering a pad in which a frame line or the like is embedded with a skin, and the pad is attached to the vehicle body.

[0004]

[Problems to be solved by the device]

 It is necessary to mold the above-mentioned LIA seat cushion and the like according to the structure of the vehicle body to which it is attached. Therefore, since the pad and the frame line are different for each vehicle body, there is a problem that the pad and the frame line molding die must be prepared respectively. Further, since the frame and the like are integrally embedded in the pad, the frame and the like are difficult to separate from the pad when the sheet is reused. Therefore, an object of the present invention is to reduce the number of conventional molding dies and facilitate the reuse of pads.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a cushion part made of foam and molded on the left and right sides of the seating surface, and a cushion body molding mold integrally formed on the body part of the cushion part. And a frame part made of a hard foam formed by molding, and the frame part is provided with a shape-retaining part formed so as to rise at least from the left and right of the frame part toward the ridge of the cushion part. It is a feature. It is desirable to form the above shape-retaining portion on the periphery of the frame portion. Further, it is preferable that the frame portion is formed of a foam having a density twice or more that of the cushion portion.

[0006]

[Action]

 Since the frame part is made of hard foam for the cushion part, it acts as a frame, and the shape retention part of the frame part keeps the ridges on the left and right of the flexible cushion part in shape retention. To be done.

【Example】

 An embodiment of the present invention will now be described with reference to the drawings. Figs. 1 to 3 show a pad (P) of a vehicle seat (a two-seat rear seat cushion for an automobile seat) according to the present invention. In the figure, (1) is a cushion part having raised portions (11) and (11) on the left and right sides of the seating surface which is the upper surface, and (2) is the cushion part using the same mold as the cushion part (1). (1) shows a frame part integrally foam-molded.

[0008] or more of the cushion portion (1) is molded by soft urethane foam having a density of about 35 Kg / m ³ to 45 Kg / m ^3, the center in the left and right direction of the ridge-like central portion (10) The seats (12) and (12) are provided on the left and right sides of the raised central portion (10). A frame portion (2) is integrally provided on the vehicle body side, which is the bottom side of the cushion portion (1).

[0009] frame section (2) is a rigid polyurethane foam comprising a density of about 80 Kg / m ³ to 100 Kg / m ^3, the wall thickness the same portions excluding the front edge and left and right side edges, were or front end The edges and the left and right side edges are formed thick to prevent deformation of the cushion portion (1).

The thickness formed along the front edge of the frame portion (2) is used as the front shape-retaining portion (21), and the thickness formed in a rising shape along the left and right side edges. The part is referred to as the shape retention part (22) (22). The front shape-retaining portion (21) described above reinforces the front side of the cushion portion (1) to prevent its deformation. Further, since the shape-retaining portions (22) (22) are formed so as to stand up in the direction of the raised portions (11) (11) of the cushion portion (1), the raised portions (11) (11) are directed outward. The shape is retained without falling.

Around the bottom surface of the frame part (2) shown in the figure, when the frame part (2) is foam-formed, a reinforcing cloth (5) (5) which is penetrated by the foaming liquid and fixedly attached is formed. It is provided. On the left and right of the bottom of the frame (2) on the bottom front side, hooks (4) formed by bending a wire into a substantially U shape are fixed to the frame (2) integrally by a mounting cloth (41). There is.

FIG. 4 shows a lyer seat cushion (SC) formed by using the pad (P), the pad (P) is covered with the skin (3), and the end of the skin (3) is reinforced with a reinforcing cloth ( 5) is integrally fixed by a tacker or the like, and the hooking piece (4) is inserted and locked in a locking hole provided in the vehicle body (B). The frame portion (2) of the pad (P) is directly supported by the vehicle body (B). In the figure, (SB) shows a rear seat back supported by the vehicle body (B), and the rear seat back (SB) has the same structure as the rear seat cushion (SC).

[0013]

According to the present invention, since the cushion portion is reinforced by the frame portion made of hard foam, the frame portion functions as a conventional wire frame. Further, the ridges of the cushion portion are retained by the ridges provided on the frame portion to prevent the deformation thereof. In addition, the frame part can be molded using the mold for cushion part molding, and since the wire rod frame is not used as in the past, the number of molds can be reduced compared to the conventional product and it is provided at low cost. In addition, since the wire frame is not embedded in the pad, the pad can be reused.
