Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a pad for a cushion used in a vehicle seat such as an automobile.

<Prior art> In general, cushion pads for vehicle seats are
It is assembled so as to be supported by a cushion spring that extends over the seat frame, and the load of the seated person is received by the elasticity of the pad and the deflection of the cushion spring, resulting in good cushioning performance. ing. The pad body of such a cushion pad may be worn or damaged due to contact with the cushion spring, and the cushion spring may give a feeling of being a foreign body when seated. For this reason, a protective cloth made of woven band cloth is stretched over the surface that comes into contact with the cushion spring by adhesive, integral molding, or the like. Conventionally, this protective cloth was woven using flame-retardant cloth, or sprayed with a flame retardant on a fabric made of untreated flame-retardant cloth, in line with recent efforts to make seats flame-retardant as a result of vehicle safety standards. , it has flame retardant properties when applied by dipping. For example, as an example of the latter, cheesecloth soaked in a vinyl chloride flame retardant is used.

<Problems to be solved by the invention> However, since conventional protective cloths are entirely flame-retardant, they are extremely expensive, and flame-retardant fabrics are difficult to obtain, leading to shortages.

The present invention has been devised in consideration of the above circumstances, and provides a cushion pad in which inexpensive and easily available protective cloth can be used.

<Means for solving the problem> The present invention uses a mixed woven fabric of a flame-retardant treated band cloth and a non-flame-retardant treated band fabric as a protective cloth. A protective cloth made of a mixed weave of and a flame-retardant untreated belt cloth is stretched over the surface that comes into contact with the cushion spring.

<Function> The protective cloth is formed by alternately weaving flame-retardant treated band fabric and non-flame-retardant treated band fabric.
Further, such a mixed woven fabric has flame retardancy as a whole and does not fall below safety standards.

<Examples> The present invention will be specifically described below with reference to illustrative examples.

FIG. 1 is a perspective view of a protective cloth applied to an embodiment of the present invention. The protective cloth 1 is constructed by interweaving warp cloth 2 and weft cloth 3. That is, the warp cloth 2 and the weft cloth 3 are woven in perpendicular directions, and are knitted so that one warp cloth 2 and the adjacent warp cloth 2 sandwich the weft cloth 3 from above and below. The weft cloth 3 is also knitted together with the adjacent weft cloths 3 so as to sandwich the warp cloth from above and below, whereby the warp cloth 2 and the weft cloth 3 are alternately interwoven to form the protective cloth 1. Here, the warp cloth 2 and the weft cloth 3 are made of band cloth made of a polyolefin synthetic resin such as polyethylene or polypropylene, and are imparted with abrasion resistance and strength. Further, the warp cloth 2 is made of such synthetic resin band cloth that has been treated with flame retardant treatment, while the weft cloth 3 is a band cloth that has not been subjected to flame retardant treatment. Flame retardant treatment can be carried out by kneading a chlorine-based flame retardant or a bromine-based flame retardant into the synthetic resin when it is dissolved to make it flame retardant at the same time as the band is formed. You may let them. Through such treatment, the warp cloth 2 is made flame retardant, and by interweaving this with the weft cloth 3 which has not been subjected to flame retardant treatment, the entire protective cloth 1 is made flame retardant. As a result of examining the flammability of the mixed-weave protective cloth 1 in accordance with the "FMVSS No. 302 Flammability of Interior Materials" test, a test value that satisfactorily passed this test was obtained. Therefore, by using such a protective cloth 1, the flame retardance of the sheet is maintained. In addition, not all of the protective cloth 1 is made flame retardant, but a part of it, the warp cloth 2 in this example, is flame retardant, and the other part, the warp cloth in this example, is flame retardant. 3 uses materials that are not subjected to flame retardant treatment, so it is possible to reduce costs, and
There is no shortage of materials.

FIG. 2 is a perspective view of the above protective cloth 1 attached to the pad 4 of the seat. The pad 4 of the embodiment is used for a bench seat of an automobile, and is formed into a predetermined shape by foam molding of polyurethane resin. This pad 4 has a recess formed on its lower surface (the illustrated embodiment shows the overturned state), and a cushion spring (none of which is shown), which is stretched around the seat frame, supports the recess. ing. The protective cloth 1 is stretched by adhesion, integral molding, etc. in the recessed part where the cushion spring comes into contact, and the stiffness prevents direct contact between the cushion spring and the pad 4, suppressing wear of the pad, and also protects the cushion. The feeling of a foreign body in the spring is reduced.

Note that various modifications can be made to the present invention. The weft cloth 3 may be subjected to flame retardant treatment, or the warp cloth 2 or the weft cloth 3 may be subjected to flame retardant treatment at intervals of one piece. Further, the weaving method of the protective cloth is not limited to that shown in the drawings, and other weaving methods may be used. Furthermore, when applied to a pad for a seat back, the protective cloth is stretched on the back of the pad.

<Effects of the invention> As described above, according to the invention, since the protective cloth is formed by interweaving the flame-retardant treated band cloth and the non-flame-retardant treated band cloth, the amount of protective cloth supplied to the market can be secured. It is effective because it can be provided at low cost.
