Description

[Detailed Description of the Invention] The present invention relates to a structure for preventing foam breakage in hanging portions of various sheets.

Conventionally, in order to prevent the seat skin from sliding when constructing a seat for a two-wheeled vehicle, for example, a button 2 or a pinch-stitched portion is provided on the surface side of the seat skin 1 with a retaining ring 2a inserted therein as shown in the first figure. Attach the inner hook of the button 2 or hook one end to the retaining ring 2a of the inner hook of the pinch stitched part, pull the hanging wire 3, and pass the axial part through the opening 4a of the cushion form 4. The seat skin 1 is suspended and stretched by fixing the end side to the bottom frame 5. However,
Even when suspended in this way, the seat skin 1 slides on the cushion form 4 due to the load of the occupant, and at that time, the suspension wire 3 that suspends the seat skin 1 may tilt diagonally. The cushion foam 4 is stretched and starts to dig into the foam layer through the openings 4a of the cushion foam 4, and if this biting becomes excessive, the foam will break. This form breakage occurs because the sliding movement of the seat skin 1 is not necessarily in one direction, but acts on the suspension wire in many directions, which causes the cushion form 4 to gradually collapse from the opening 4a. .

The present invention provides a structure for preventing the suspension from breaking due to the above-mentioned suspension wire, which is ingeniously devised to prevent the cushion foam from being cut by the suspension wire.
With the goal.

That is, in the structure for preventing form breakage of the suspension part according to the present invention, a tubular member having a relatively large diameter through which the suspension wire is passed is attached on the axis of the suspension wire,
By positioning the tubular member in the opening of the cushion form and inserting the suspension wire into the opening of the cushion form, the seat skin is suspended and fixed to the bottom plate by the suspension wire. ing.

Hereinafter, this will be explained based on the diagram shown in FIG. 2 as follows.

This embodiment constitutes a seat for a two-wheeled vehicle, and the suspension of the seat skin 1 is constructed in the same manner as that shown in the first figure.

The sheet skin 1 is made up of a skin material 1a and a backing sheet material 1.
It is formed of a trim cover with a foam material 1c interposed between it and the seat cover 1, and in order to suspend the seat skin 1, retaining rings 2a for the buttons 2 are provided at important points on the surface.
There is a small hole for inserting. The button 2 is constructed by inserting a retaining ring 2a into the seat through a small hole in the seat skin 1, and by twisting and securing one end of a hanging wire 3 such as a thread or wire to the retaining ring 2a, the suspending wire 3 is pulled downward. It is designed to be attached and fixed to the surface of the seat skin 1 with a tension of . The hanging wire 3 is tensioned by inserting the downwardly pulling axis into the vertical hole 4a formed in the cushion form 4, and connecting and fixing the lower end to the button 6 which is placed against the lower surface of the bottom plate 5. It is set up and arranged. In this suspension structure, a tubular member 7 is attached to the axis of the suspension wire 3 passing through the vertical hole 4a of the cushion form 4. The tubular member 7 can be formed of PO, rubber, or the like into a cylindrical columnar shape, a truncated cone, or a cylindrical bellows structure with a relatively large diameter. The axis of the hanging wire 3 is inserted into the diameter, and in the illustrated embodiment, the upper end of the tube is fixed to the retaining ring 2a of the button 2, and the lower end of the tube is clipped onto the axis of the hanging wire 3. , a tubular member 7 is attached on the axis of the suspension wire 3.

With the structure for preventing foam breakage of the hanging portion configured in this way, even if the seat skin 1 slides on the cushion form 4 and the axis of the hanging wire 3 is pulled diagonally, the tubular member 7 This prevents the suspension wire 3 from digging into the foam layer when it hits the cushion foam 4, and since the tubular member 7 has a relatively large diameter, simply denting the foam layer will cause the foam to break. You can prevent it from happening.

As described above, according to the structure for preventing form breakage of the hanging part according to the present invention, it is possible to completely prevent the form from being cut by the hanging wire with a relatively large diameter tubular member attached on the axis of the hanging wire. , which improves the durability of the sheet in use.
