Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a surface skin fastening structure for fastening the seat skin to an inner peripheral wire frame that is in direct contact with the back side of a seat pad.

Conventionally, when attaching the seat skin etc. to the seat frame etc., as in the conventional example shown in FIG. A wire made of iron wire, paper, resin, etc. is passed through as a core wire 2, and this core wire 2 is passed through a bag portion 3 to the inner wire frame 4 of two wire frames that are in direct contact with the back side periphery of the seat pad of the seat. It is common practice to drive a hog ring 5 across the core wire 2 and the wire frame 4 with an air tool to bind them together and attach them to the seat skin or the like.

Generally, when using an air tool to drive hog rings, the air tool is heavy, which causes worker fatigue and reduces work efficiency.
The edges of the seat skin, etc., which are secured with hog rings at multiple locations, have the disadvantage that the portions between the hog rings are pulled and curl up, resulting in a wavy phenomenon, and the edges of the seat cannot be finished smoothly.

This invention facilitates the work of securing the seat skin, etc., improving work efficiency, and also supports the edges evenly with the appropriate length of the securing device, thereby preventing the waving phenomenon of the edges of the seat skin, etc. The purpose of this is to provide a smooth finish to the edges of the seat skin, etc.

For this reason, this device is designed to use a long belt-shaped locking device that connects the seat skin, etc., with a flat plate portion that makes surface contact with the surface of the seat pad, and a locking protrusion that locks onto an object. Fix the attachment to the peripheral edge of the seat skin, etc., fold it back so as to wrap the edge of the seat skin, etc. inward, and then insert the fastening device in the direction in which the skin, etc. receives tensile force. It is characterized in that it is inserted between a sheet pad made of urethane or the like and a wire frame that directly contacts the inner circumferential edge of the back side of the sheet pad.

Next, embodiments of this invention will be described with reference to the accompanying drawings, FIGS. 2 to 8.

FIG. 2 is a perspective view of a rear seat suitable for implementing the fastening structure of this invention, in which 11 is a seat cushion, 12 is a seat back,
In either case, the seat skin is stretched over a seat pad made of urethane or the like without using springs or the like.

FIG. 3 is a perspective view showing the seat cushion 11 turned over, in which a seat skin 14 is stretched over the surface of the seat pad 13 made of urethane material, and the edge part 15 of the skin is It is attached in a fixed configuration.

FIG. 4 is a longitudinal sectional side view of a portion of the seat showing the state in which the skin of the seat is engaged, and 16 is a fastening device.

This fastening device 16 has a T-shaped cross section as shown in FIG. Weld and fix.

Further, the locking protrusion 18 projecting perpendicularly from the flat plate portion 17 is set to have a height comparable to the diameter and height of the hanging wire or the like that is the object to be locked.

When the anchoring device 16 is used for anchoring,
As shown in FIG. 4, the periphery 15 of the seat to which the fastening device 16 is fixed is once folded back, and the space between the seat pad 13 of the seat and the inner wire frame 19 that is in direct contact with the periphery of the back side of the seat pad 13 is folded back. At this time, the flat plate portion 17 of the fastening tool 16 comes into contact with the back side of the seat pad 13, and the fastening tool 16 is inserted so that the fastening protrusion 18 is fastened to the wire frame 19.

That is, the anchoring tool 16 is pressed by the weight of the seated person via the seat cushion so that the flat plate portion 17 does not rotate.
The locking protrusion 18 of 6, one side of the flat plate part 17, and the folded seat skin 14 fixed thereto surround the wire frame 19, and the seat skin is further pulled. The locking protrusion 18 is pressed against the skin of the sheet to ensure its locking to the wire frame 19.

Next, an anchor 1 having a J-shaped cross section as shown in FIG.
The case where 6 is used will be explained.

Similar to the fastening tool 16 shown in FIG. 5, the fastening tool 16 shown in FIG.
are fixed by the same means.

However, the locking protrusion 2 protruding from this flat plate part 17
0 is bent into a semicircular arc shape (or hook shape, etc., although not shown) to match the shape of the wire frame 19, etc., so that it can be bent into the shape of a hook 16 as shown in FIG. The band-shaped flat plate part 17 comes into contact with the surface of the seed pad 13, and the locking protrusion 20 bent into a semicircular arc locks the wire frame 19 so as to wrap around it. Since it is folded back and wrapped, the attachment can be made more secure.

Note that the fastening tool 16 shown in FIG. 6 has the same structure as the one shown in FIG. 5, such as being a long belt-like object.

The above-mentioned fastening device 16 is attached to the entire edge circumferential side of the seat skin, but if the edge circumferential side of the skin is continuous by a corner with a relatively large radius, The above-mentioned fastening tool 16 is bent along the corner and attached continuously.

However, if the corner is an acute angle, it is also possible to install it separately before and after the corner.
Further, they can also be attached at appropriate intervals even on straight sections.

As described in detail above, according to the fastening structure of the present invention, the work process using air tools can be omitted, and since the fastening tool is continuous to an appropriate length, the first end can be connected to the back surface of the seat pad and the wire frame. Once inserted between the two, all you have to do is gently push it in toward the rear end, and it will be engaged continuously in a linear manner, making it easy to attach the skin, etc., and improve work efficiency.

Further, since the folded portion of the seat skin that forms a bag on the circumferential edge of the seat can be omitted, the amount of expensive skin material used can be reduced and costs can be reduced.

Furthermore, since the seat skin, etc. is attached to the seat by means of an appropriate length of anchoring device attached to the entire edge of the seat, the tension applied to the seat skin, etc. is supported evenly across the entirety of this attachment part. The skin, etc. of the seat does not roll up in a wavy manner, and the outer shape of the seat and the ends of the skin, etc., are smooth and beautifully finished.

In addition, when this fastening device is engaged with the wire frame, its belt-like flat plate portion is constantly pressed in the plane direction by the seat pad and rotation is prevented, so that separation from the wire frame is almost completely prevented. The skin is securely attached to the wire frame with the seat pad covering it. In particular, when the seat is seated, the fastening device is pressed even more strongly in the plane direction, completely preventing its rotation, so there is no risk of it accidentally coming off even when seated roughly, and the skin remains secure without peeling. It has the effect of being retained and attached to.
