Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a seat skin end fixing structure that can be applied to, for example, assembling seats for special vehicles such as lawn mowers and tractors.

BACKGROUND TECHNOLOGY Conventionally, when assembling the above-mentioned seat, as shown in FIG. 3, the end of the seat skin 4 is applied to the stepped portion 2 of the bottom frame 1 with a belt molding 5, and the belt molding 5 is opened with a slit along the longitudinal direction. The end of the seat skin 4 is fixed to the bottom frame 1 by driving a tassel needle 6 into the bottom surface from the inside.

Problems to be Solved by the Invention However, in this seat skin end fixing structure, when the load of the occupant is applied to the seat surface, the seat skin 4 is pulled and the cushion pad 3 is compressed inward, causing the belt molding to tighten. 5 is exposed on the front side, which is unfavorable in terms of appearance, and the tensile force applied to the seat skin 4 from the point where the seat skin 4 is fixed to the bottom frame 1 with the tassel needle 6 is applied to the fixing hole of the tassel needle 6. There is a possibility that the end of the seat skin 4 may be cut out from this location due to concentration. In addition, when the seat is exposed to rainwater, it is impossible to prevent the rainwater seeping into the gap between the seat skin 4 and the belt molding 5 from going around to the lower surface side of the seat skin 4 and penetrating into the cushion pad 3.

An object of the present invention is to provide a seat skin end fixing structure that can maintain the appearance well and prevent the end of the seat skin from breaking and rainwater from entering the cushion pad.

Means for Solving the Problems In the seat skin end fixing structure according to the present invention, the cushion pad is covered with a belt molding provided along the longitudinal direction with a slit that can be flipped open near the upper end of the vertical wall. Hold the end of the seat skin in your mouth, lock the end of the seat skin with the slit edge of the vertical wall, fix it to the inner side of the belt molding, and attach the end of the seat skin to the peripheral edge of the bottom frame via this belt molding. When attaching the seat skin and belt molding, use a tatker needle driven from the inside of the belt molding to fix the end of the seat skin together with the belt molding to the peripheral edge of the bottom frame. Moreover, this belt molding can be assembled by fitting and fixing it to a step provided along the peripheral edge of the bottom frame.

Function: With this seat skin end fixing structure, the end of the seat skin is gripped by the belt molding and secured at the slit edge of the standing wall, so even if the seat skin is pulled due to the load of the occupant, the standing wall maintains its rigidity. By being able to hold it against the seat, the appearance can be maintained well without exposing the thickness of the belt molding to the front side or opening the belt molding with a slit, and the tensile force applied to the seat skin can be dispersed by the standing wall part. This prevents stress from concentrating on the stopper hole even when the end of the seat skin is fastened with a tatker needle, which prevents the end from breaking.Furthermore, even if rainwater enters the interior through the gap between the seat skin and the belt molding, it will not cause damage to the vertical wall. It can be prevented from entering the cushion pad from the place where it can be blocked. In addition, when assembling this, by providing an L-shaped notch in the peripheral edge of the bottom frame and fixing the belt molding against it, you can not only position and fix the belt molding, but also
Since the belt molding can be installed without exposing the thickness of the belt molding to the rear side, it can be assembled in the most aesthetically pleasing manner.

Embodiment The most preferred embodiment will be described below with reference to FIG. 1.

This end-fixing structure of the seat skin can be applied to assembling seat backs or seat cushions for seats equipped on special vehicles such as lawn mowers and tractors. When a cushion pad 11 made of urethane foam or the like is placed on the bottom frame 10 and a seat skin 12 made of polyvinyl chloride or the like is applied to the seat side, the seat skin 1 is
This can be applied to fixing the terminals of No. 2 to the peripheral edge of the bottom frame 10.

The bottom frame 10 is provided with a stepped portion 13 by notching the peripheral edge in an L-shape.
Further, a belt molding 14 is fitted and fixed to this stepped portion 13, and holds the end of the seat skin 12 covering the cushion pad 11. As the belt molding 14, it is possible to use a hollow resin member having a substantially housing-shaped cross section and having a slit 14b along the longitudinal direction near the upper end of the standing wall portion 14a, the inside of which can be flipped open. This belt molding 1
4 has a slit 14b on the end side of the seat skin 12.
The seat skin 1 is inserted into the inside of the vertical wall portion 14a and is locked with the slit edge of the vertical wall portion 14a, and the seat skin 1 is inserted along the inner bottom surface of the vertical wall portion 14a.
2 terminals are fixed. Further, by positioning and fixing this belt molding 14 to the step portion 13, the end of the seat skin 12 is fixed together with the belt molding 14 to the peripheral edge of the bottom frame 10. To fix it, by bending and deforming the upper part from the slit 14b, the belt molding 14 is fixed to the bottom frame 10 together with the end of the seat skin 12 using the tacker needle 15 driven into the inner bottom surface from the inside. be able to.

With the seat skin end fixing structure configured in this way, even if the seat skin is pulled due to the load of the occupant, the vertical wall portion 1 of the belt molding 14 will absorb the tensile force.
Since the shape can be maintained by opposing the belt moldings 4a, at least the thickness of the belt molding 14 will not be exposed to a large extent on the front side.In addition, if the step part 13 is formed on the peripheral edge of the bottom frame 10, the belt molding 14 can be fitted and fixed, so the assembly can be assembled into an extremely aesthetically pleasing item without exposing the thickness on the rear side. In addition to this, the seat skin 12
Even if the terminal is fixed with the tack needle 15, the tensile force applied to the seat skin 12 can be received by the vertical wall portion 14a, so stress is not concentrated at the fixing hole of the tack needle 15, thereby preventing the end of the seat skin 12 from being cut. Furthermore, even if rainwater enters through the gap between the seat skin 12 and the belt molding 14, the cushion pad 11 can be prevented by the vertical wall portion 14a.
Since it is possible to prevent the rubber from penetrating into the skin, it is possible to maintain good cushioning properties for many years.

Effects of the invention As described above, according to the seat skin end fixing structure according to the present invention, the end of the seat skin can not only be fixed to the bottom frame with good appearance and mechanical strength, but also can be attached to the cushion pad. It also prevents rainwater from entering, making it possible to maintain good cushioning properties for many years.
