Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a trim terminal fixing structure for a vehicle seat.

[0002]

[Prior art]

 Conventionally, an automobile seat is composed of a seat cushion 1, a seat back 2 and a headrest 3 as shown in FIG. 4. For example, the seat cushion 1 is a synthetic resin seat as shown in FIG. The surface of the pad 5 set on the frame 4 is covered with a trim 6, and the end 6a of the trim 6 is fixed to the bottom of the seat frame 4 by a number of metal staples (steaples) 8.

[0003]

[Problems to be solved by the device]

 However, the trim 6 is manually fixed by pulling the trim 6 toward the end while providing the tension, while fixing the end 6a to the seat frame 4 with the stop needle 8. Due to variations in the fixed position of the needle 8, the trim line is apt to be twisted, and the trim 6 is apt to be wrinkled, which deteriorates the appearance. In addition, there is a problem that it is difficult to fix the trim 6 with the stop needle 8 while pulling the trim 6.

Therefore, an object of the present invention is to provide a trim terminal fixing structure for a vehicle seat, which has an improved appearance and can easily fix the trim terminal.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a trim terminal fixing structure for an automobile seat in which the surface of a pad set on a seat frame is covered with a trim and the end of the trim is fixed to the seat frame. A plate having fixing holes formed at predetermined intervals is attached to the terminal, the fixing holes of the plate are fitted from above into the seat frame, and a positioning protrusion capable of being heat-squeezed is formed at the upper end. It is characterized by that.

[0006]

[Action]

 According to the present invention, a plate having a fixing hole is attached to the end of the trim in advance, and the upper end of the protrusion is heat crimped while the fixing hole of the plate is fitted into the positioning protrusion of the seat frame.

By fitting the plate into the positioning protrusion of the seat frame, the trim is pulled toward the end to provide a uniform tension, and in this state, the protrusion may be heat caulked to fix the plate to the seat frame. Therefore, the pulling force of the trim does not vary, and the fixing position by the protrusion does not vary, so the trim line does not twist and wrinkles do not occur in the trim, improving the appearance. Further, the trim terminal can be easily positioned by simply inserting the fixing hole of the plate into the protrusion of the seat frame, and the protrusion is simply heat-crimped, so that the fixing work can be performed easily and accurately. Furthermore, the number of parts is reduced because a large number of stop needles are not required.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. As shown in FIGS. 1 and 2, a pad 11 is set on the upper surface of a seat frame 10 made of synthetic resin of the seat cushion 1, and the surface of the pad 11 is covered with a trim 12.

A rectangular plate 13 is sewn on the upper surface of the end 12a of the trim 12 with a sewing thread (not specifically shown) at an appropriate pitch. The plate 13 is manufactured, for example, by extrusion molding of synthetic resin and cut into a suitable length. The plate 13 may be attached to the upper surface of the end 12a of the trim 12 with an adhesive or the like. Fixing holes 13a are formed in the plate 13 at predetermined intervals, and the fixing holes 13a penetrate the end 12a of the trim 12.

On the upper surface of the seat frame 10, there is provided a positioning protrusion 10a into which the fixing holes 13a of the plate 13 can be fitted from above at a position where the trim 12 is pulled toward the end to provide a uniform tension. It is formed integrally.

With the above configuration, the plate 13 is attached to the upper surface of the terminal 12a of the trim 12 in advance by sewing or the like.

By covering the surface of the pad 11 with the trim 12 and fitting the fixing hole 13a of the plate 13 into the positioning protrusion 10a of the seat frame 10 from above, the trim 12 is moved toward the end of the plate 13 by the plate 13. It is pulled to give a uniform tension. In this state, as shown in FIG. 3, when the upper ends 10b of the positioning protrusions 10a of the seat frame 10 are caulked by heat and expanded to a head shape, the plate 13 is fixed to the seat frame 10 by the respective protrusions 10a. Like

Since the plate 13 is positioned by the protrusion 10a of the seat frame 10, the pulling force of the trim 12 does not vary, and the fixing position by the protrusion 10a does not vary, so that the trim line is It is not twisted, and the trim 12 is not wrinkled. From these points, the appearance is improved.

On the other hand, the terminal 12a of the trim 12 can be easily positioned by simply inserting the fixing hole 13a of the plate 13 attached to the upper surface of the terminal 12a of the trim 12 into the positioning protrusion 10a of the seat frame 10. Further, since the positioning protrusion 10a of the seat frame 10 is merely caulked, the fixing work can be performed easily and accurately. Moreover, since a large number of retaining needles as in the conventional case are unnecessary, the number of parts is reduced.

[0015]

[Effect of device]

 As is clear from the above description, in the trim terminal fixing structure of the present invention, the plate having the fixing holes is previously attached to the end of the trim, and the fixing holes of the plate are fitted with the positioning projections of the sheet frame. In this state, the upper ends of the protrusions are heat-crimped.

Therefore, by fitting the plate into the positioning protrusion of the seat frame, the trim is pulled toward the end to provide a uniform tension, and in this state, the protrusion is heat-staked to fix the plate to the seat frame. Since the pulling force of the trim does not fluctuate and the fixing position by the protrusion does not fluctuate, the trim line does not twist and wrinkles do not occur on the trim, improving the appearance. Come to do. In addition, the trim end can be easily positioned by simply inserting the plate fixing hole into the seat frame protrusion, and the protrusions can be heat crimped so that the fixing work can be performed easily and accurately. . Furthermore, since a large number of stop needles are not required, the number of parts can be reduced.
