Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a trim cover forming apparatus for a vehicle seat, and more particularly, to a trim cover forming apparatus for covering a foam cushion body molded into a seat shape of a substantially seat.

[0002]

[Prior art]

 The seating surface of the cushion body is recessed in the center and is formed in a raised shape on the left and right sides to improve the seatability of the seated person. The cushion body is covered with a trim cover, and the trim cover is attached to the cushion body with an adhesive to assemble the seat.

The above-mentioned trim cover is formed by pressing a flat cloth on the upper and lower molds before adhering to the cushion body so that it is covered with wrinkles and slacks along the uneven seat surface shape of the cushion body. Is used to form the uneven shape by pressing to correspond to the uneven seat surface shape of the cushion body.

By the way, the molding of the trim cover with a press is performed by placing the trim cover on the lower mold and pressurizing (or pressurizing and heating) it with the upper mold. The trim cover is placed on the lower mold so that there is a gap between the trim cover and the pressing surface of the lower mold, which is formed to match the finished shape of the trim cover in consideration of the degree of extension. After that, the upper mold is lowered and the entire trim cover is simultaneously pressed against the pressing surface of the lower mold.

[0005]

[Problems to be solved by the device]

 However, at this time, the timing of the upper mold contacting the center part of the trim cover and both sides causes a deviation due to the dimensional variation of the trim cover and the gap between the trim cover and the lower mold. There was a problem that the cover could not be positioned at the specified position and the trim cover could not be molded properly. Therefore, the present invention aims to eliminate such defects of the conventional products.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the trim cover molding apparatus according to the present invention is provided with a positioning guide projecting from the pressure surface of either the lower mold or the upper mold and projecting the guide. In either direction by a spring, or one of the upper die and the lower die is supported by an elastic body, and the base end is fixed to the base on this die, and the tip protrudes from the pressing surface of the die. It is a structure that penetrates the guide. It is preferable that the guides are arranged at least at two places on the pressing surface of one mold.

[0007]

[Action]

 When one of the molds is moved in the other mold direction to pressurize the trim cover, first, a part of the trim cover is brought into contact with the positioning guide to position the trim cover on the other mold side. In this positioned state, the trim cover is pressed by the pressing of one mold against the other pressing surface, and the trim cover is formed in an uneven shape.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of the present invention. In this embodiment, a guide (5) is embedded in an upper mold (1) with its tip freely retractable, and then embedded in the upper mold (1). The guide (5) is formed so that its tip projects from the pressing surface of the upper mold (1) by the elastic force of the spring (3), and the guide (5) is mounted on the lower mold (2). It is arranged so as to correspond to the joining point (60) of 7). In addition, a protrusion (20) having a mountain-shaped cross section is provided at a contact portion (60) of the trim covers (6) and (7) on the pressing surface (22) (23) of the lower mold (2).

The pressing surfaces (22) and (23) of the lower mold (2) are attached to the central portion (22) so as to coincide with the surface of the foam cushion body foam-molded into the seating surface shape of the seat. The left and right parts (23) and (23) are formed in a raised shape, and the pressing surface of the upper die (1) is also formed to correspond to the pressing surface of the lower die (2).

The trim covers (6) and (7) are synthetic resin woven fabrics and films having elasticity, and the frame (7) and (7) are integrally joined to the body (6). In the trim covers (6) and (7), as shown in FIG. 1, the stitching points (60) and (60) of the trim covers (6) and (7) are located on the protrusions (20) of the lower mold (2). The lower mold (2) is then turned over and placed. In this state, the guides (5) (5) of the upper mold (1) are located on the protrusions (20) (20) of the lower mold (2), and the guides (5) (5) are metal, It is made of a rigid material such as hard synthetic resin and is molded into a plate that is attached by hand without falling off the upper mold (1). In FIG. 1, (4) in the figure shows a base for supporting the lower mold (2), and (41) shows a mounting seat for fixing the lower mold (2) to the base (4).

FIG. 2 shows a state in which the upper die (1) is lowered from the state of FIG. 1, and when the upper die (1) is lowered, the elastic force of the spring (3) applies a force to the upper die (1). The guide (5) whose tip projects from the pressure surface first contacts the protruding portion (21) of the lower mold (2) with the jointing portion (60) which is a part of the trim cover (6) (7). Press. As a result, the trim covers (6) and (7) are positioned with respect to the lower mold (2) and the upper mold (1).

Further, when the upper mold (1) is lowered, as shown in FIG. 3, the trim covers (6) and (7) are positioned, and the entire trim covers (6) and (7) are added. By pressing, the trim covers (6) and (7) are formed into the shapes of the pressing surfaces (22) and (23) of the lower mold (2). At that time, the tip of the guide (5) is submerged in the upper mold (1) against the elastic force of the spring (3). After forming the trim covers (6) and (7) in a concavo-convex shape, the upper mold (1) is raised and removed from the lower mold (2) to obtain a vehicle seat trim cover. The vehicle seat is assembled by adhering the cover to the foam cushion body.

4 to 6 show a second embodiment of the present invention, in which a lower mold (20) is mounted on a pedestal (40) and a compression spring, a foam or a rubber cushion is used. From the protrusions (21) and (21) provided on the pressing surfaces (22) and (23) of the lower mold (20) while supporting them through elastic bodies (30) (30) (30) such as materials. A slit (24) is provided on the lower side, and an upright guide (50) (50) having a base end fixed on a base (40) is passed through the slit (24), and the guide (50) ( The tip of the protrusion (50) is projected upward from the protrusions (21) and (21), while the protrusions (21) and (21) of the lower mold (20) are attached to the pressing surfaces (11) and (13) of the upper mold (10). ) Corresponding to the groove (12) (12).

FIG. 4 shows a state in which the trim covers (6) and (7) are placed on the lower mold (20), and the joining points (60) of the trim covers (6) and (7) are shown in FIG. As described above, the guides (50) (50) projecting from the protrusions (21) (21) of the lower mold (20) are locked to the tips.

When the upper die (10) is lowered from the state shown in FIGS. 4 and 5, first, the protrusions (21) (21) are used to join the trim covers (6) and (7) to the joining points (60) (60). ) Abuts on the upper mold (10) side, and by this upper mold (10) and the lower mold (20), the joining point which is a part of the trim covers (6) (7) is located on the upper mold (10). It is positioned in the groove (12) (12).

After that, when the upper mold (10) is further lowered, the trim covers (6) and (7) are in a fixed state, and the entire pressure surfaces (11) and (13) of the upper mold (10) are entirely covered with the trim cover ( 6) (7) is joined, and the lower mold (20) also resists the resilience of the elastic bodies (30) ... As shown in FIG. By the upper mold (10) and the upper mold (10), the trim covers (6) and (7) are formed in an uneven shape.

[0017]

[Effect of device]
