Description

[Detailed description of the invention] The present invention is a fixing structure for the skin of an automobile seat. Specifically, a roughly J-shaped hanging rod is provided along the end of the skin, and this hanging rod is placed inside the lower rod line. The present invention relates to a structure for fixing the skin of an automobile seat, in which the skin is fixed by hooking the skin to a trim wire arranged along the seat.

(Prior art) In the case where a substantially J-shaped hanging rod is attached by sewing or the like along the end of the skin, the hanging rod is placed inside the lower frame line at a predetermined interval. Since it can be easily hooked onto the trim wire, it is easy to fix the skin and the workability is very high. However, according to this method,
As shown in FIG. 5, at the intersection A of the trim wire 10 and the reinforcing wire 11 perpendicular to the trim wire 10, the latching rod 2 butts against the reinforcing wire 11, so there is a problem that the trim wire 10 cannot be latched. This is because the reinforcing wire 11 is attached to the trim wire 10 on substantially the same plane as shown in FIG. Therefore, it is not possible to use a single hanging rod 2 by sewing it along the end of the skin, so a large number of short hanging rods 2 cut at each attachment interval of the reinforcing wire 11 to the trim wire 10 are used to attach the reinforcing wire 11 to the trim wire 10. It was sewn to the terminal. Therefore, not only the workability of the sewing work is poor, but also the efficiency of the work of hooking the trim wire 10 is poor.

Note that the seat has a lower frame line 3 and a trim wire 10.
A cushion body 4 made of foam is integrally foamed onto a frame made of reinforcing wires 11 which are arranged orthogonally thereto and fixed by spot welding, and then the outer skin 1 is attached to the cushion body. 4, and the hooking rod 2 provided at the end of the skin 1 is hooked to the trim wire 10, thereby assembling the trim wire 10.

(Purpose) The purpose of the present invention is to eliminate such defects of conventional products. That is, the present invention is to attach a single hanging rod to the end of the skin by sewing or the like so that it can be hung on the trim wire.

(Structure) The present invention has the above-mentioned trim wire and a reinforcing wire installed orthogonally to the trim wire, so that the trim wire at the intersection thereof is directed toward the lower frame, and the reinforcing wire is directed toward the inside of the seat in a U-shape. The latching rod can be latched at the intersection of the reinforcing wire in the trim wire.

(Example) Fig. 1 is a perspective view showing an automobile seat (rear seat cushion) having a skin fixing structure according to the present invention turned over. A hanging rod is fixed along the end of the opening by sewing, high-frequency welding, adhesive, etc., and this hanging rod 2 is made of synthetic resin (polypropylene, polypropylene, etc.).
It is made of (vinyl chloride, etc.), is flexible in the longitudinal direction, and has a U-shaped hook integrally formed at its tip. In the figure, reference numeral 3 denotes a lower frame line that is bent and formed into the outer shape of the bottom of the seat, and trim wires 5 are arranged inside this lower frame line 3 at predetermined intervals. Note that 4 indicates a cushion body made of foam. The trim wire 5 and the lower frame line 3 are reinforced by reinforcing wires 6, 6, . . . . This will be explained in detail with reference to FIG.

FIG. 2 shows a frame assembly consisting of a lower frame line 3, a trim wire 5, reinforcing wires 6, 6, etc. showing the essential parts of the present invention, and the intersections of these wires are welded by spot welding. The intersection portions of the reinforcing wires 6, 6, . . .
6a..., 5a, 5a... are provided, and the epidermis 1
A latching rod 2 provided at the terminal of the holder is configured to be able to be latched. That is, the bent portions 6a, 6a of the reinforcing wires 6, 6... are U-shaped in the direction of the cushion body 4, and the bent portions 5a, 5 of the trim wire 5 are formed in a U-shape in the direction of the cushion body 4.
a... are each bent into a U-shape in the direction of the lower frame line (Fig. 4). In addition, the reinforcing wires 6, 6
... are spot welded at the intersections at the center of the bent portions 5a, 5a... of the trim wire 5.

FIG. 3 shows the state in which the retaining rod 2 is engaged with the trim wire 5. Since the reinforcing wire 6 is provided with a bent portion 6a that is bent in the direction of the cushion body 4, the long hanging rod 2 provided at the end of the skin 1 is hooked to the trim wire 5, so that the skin 1 is Once secured, the rear seat cushion shown in FIG. 1 is assembled.

Note that the locking rod 2 is not locked at the bent portion 5a of the trim wire 5, but is locked at other portions, so that it will not be removed. Moreover, since the cushion body 4 is pressed when the locking rod 2 is locked, the locking rod 2 is constantly pulled by the elastic force of the cushioning body 4, so there is no risk of it being removed. In addition, the latching rod 2 is attached to the first
As shown in the figure, it is optional to provide notches 2a, 2a, . . . to allow easy bending in the length direction.

(Effects) Since the present invention is configured as described above, it has the following effects.

(1) In the present invention, one hanging rod can be provided along the end of the skin, so there is no need to sew a large number of hanging rods to predetermined positions at the end of the skin, unlike conventional products. Therefore, the work of attaching the hanging rod to the skin can be improved.

(2) Since the present invention can use a single hanging rod, it can be continuously and easily fixed to the trim wire. Therefore, the workability of the fixing work is improved compared to the conventional product in which a large number of latching rods are respectively fixed to predetermined positions on the trim wire.

(3) Since the skin is fixed to the trim wire with a single hanging rod, the entire skin can be applied evenly. Therefore, unlike conventional products, wavy wrinkles do not occur near the ends of the skin, and the finish as a sheet is improved.
