Abstract

<P>PROBLEM TO BE SOLVED: To reduce the bleeding of a urethane liquid to the surface of a non- woven fabric at the time of molding, and to prevent noises by the friction with a steel material such as a spring from being generated for a seat pad equipped with the non-woven fabric as a backing material. <P>SOLUTION: This seat pad 1 is obtained by setting the non-woven fabric 4 in a molding die 5, injecting an expandable urethane liquid 8 and performing expansion-molding. In this case, the non-woven fabric 4 is expanded integrally with the surfaces of areas which come into contact with the steel material such as the spring 2 in the expansion-molded polyurethane foam for the seat pad 1. In the seat pad 1, as the non-woven fabric 4, a non-woven fabric being constituted of a fiber of which the cross sectional shape is flat, and of which the air permeability is 20 to 200 cc/cm<SP>2</SP>/second is used. <P>COPYRIGHT: (C)2004,JPO

2. Description of the Related Art As a seat pad used for a vehicle or furniture seat, a flexible polyurethane foam molded article obtained by injecting a foamable urethane liquid into a molding die and foaming is mainly used. Such a seat pad is usually assembled on a seat frame provided with a spring and configured as a seat. Therefore, the back surface of the seat pad is always in contact with and rubbed with a steel material such as a spring or a frame, and the durability cannot be ensured by the soft polyurethane foam alone. Therefore, conventionally, a reinforcing base cloth such as a non-woven fabric is provided as a backing material on the back surface of the seat pad that comes into contact with a spring or the like to ensure durability.

When the back surface of the seat pad is reinforced with a non-woven fabric as described above, it is desired that the non-woven fabric is sufficiently impregnated with the urethane liquid from the viewpoint of merely enhancing the reinforcement effect. If it leaches out, there is a problem that the polyurethane film formed thereby rubs against a steel material such as a spring, resulting in abnormal noise. While such noise is required to be quiet in particular in recent years, it can be reduced as much as possible in vehicle seats such as automobiles where friction between a seat pad and a spring is likely to occur due to vibration during traveling. It has been demanded.

In Japanese Patent Laid-Open No. 1-299009, in order to prevent the generation of such abnormal noise, a urethane liquid is impregnated only in a portion other than the surface of a non-woven fabric provided in a portion in contact with a steel material such as a spring. It is disclosed. However, the publication does not disclose a specific structure of the nonwoven fabric for that purpose. If the thickness of the non-woven fabric is sufficiently large, it is possible to suppress the exudation of the urethane liquid to the non-woven fabric surface to prevent abnormal noise in the non-woven fabric of a thickness that does not impair the good cushioning properties of polyurethane foam. It is not easy to prevent.

The present invention has been made in view of the above circumstances, and in a seat pad provided with a non-woven fabric as a backing material, the exudation of urethane liquid onto the surface of the non-woven fabric at the time of molding is reduced to prevent a spring or the like. The purpose is to prevent the generation of abnormal noise due to friction with the steel material.

The seat pad of the present invention is a seat pad obtained by setting a non-woven fabric in a molding die, injecting a foamable urethane liquid and foam-molding the foamed polyurethane. In a sheet pad in which the non-woven fabric is integrally foamed on the surface of a portion of the foam that contacts the steel material such as a spring, the non-woven fabric is a non-woven fabric composed of flat fibers having a cross-sectional shape.

The nonwoven fabric used as the backing material for the seat pad in the present invention has a low air permeability because each fiber has a flat cross-sectional shape. Therefore, the urethane liquid is less likely to seep out to the surface of the nonwoven fabric during foam molding, and therefore abnormal noise due to friction with the steel material such as the spring can be prevented.

In the seat pad of the present invention, it is preferable that the nonwoven fabric has an air permeability of 20 to 200 cc / cm 2 / sec. As a result, the inside of the non-woven fabric is appropriately impregnated with the urethane liquid. Therefore, while the adhesive strength of the non-woven fabric to the polyurethane foam is sufficiently ensured, the leaching of the urethane liquid onto the non-woven fabric surface can be prevented.

BEST MODE FOR CARRYING OUT THE INVENTION The non-woven fabric used as the backing material in the seat pad of the present invention is a non-woven fabric composed of fibers having a flat cross section. This nonwoven fabric has a low air permeability because each of the constituent fibers has a flat cross-section.
The flatness of the constituent fibers, that is, the ratio of the minimum dimension to the maximum dimension in the cross-sectional shape of the fiber (minimum dimension / maximum dimension) is 8
It is preferably in the range of -12. It is preferable that all the fibers constituting the non-woven fabric are the above-mentioned flat fibers, but non-flat fibers may be mixed within a range not impairing the effect of the present invention.

The air permeability of the above nonwoven fabric is 20 to 200 cc /
It is preferably in the range of cm 2 / sec. Here, the air permeability is a value measured by a method using a Frazier type tester specified in JIS L 1096 6.27.1 A method. When the air permeability of the non-woven fabric is less than 20 cc / cm 2 / sec,
The urethane liquid may not be sufficiently impregnated into the nonwoven fabric during foam molding, so that sufficient adhesive strength between the polyurethane foam and the nonwoven fabric may not be obtained. On the other hand, the air permeability is 200
If it exceeds cc / cm 2 / sec, the amount of the urethane liquid leaching to the surface of the nonwoven fabric during foam molding may increase, and a sufficient noise preventing effect may not be obtained. The more preferable range of air permeability is 50 to 80 cc / cm 2 / sec.

As the above-mentioned non-woven fabric, a long-fiber non-woven fabric made of polyolefin fiber, more preferably polypropylene fiber is preferable. By using the long fiber non-woven fabric, abrasion resistance can be secured as a backing material. It is preferable that the nonwoven fabric is not needle-punched, and in that case, since it has no needle hole, it is possible to secure the shielding property for preventing the urethane liquid from seeping out.

When molding the seat pad (1), the upper mold (7) is opened to set the non-woven fabric (4), and a foaming urethane liquid (8) is applied to the lower mold (6) by an injection device (not shown). Is injected in a predetermined amount and the upper mold (7) is closed. The injected foamable urethane liquid (8) fills the mold (5) while foaming, whereby the flexible polyurethane foam is foam-molded in the mold (5). At that time, the urethane liquid (8) that expands while expanding reaches the position of the nonwoven fabric (4) and impregnates the nonwoven fabric (4), but the nonwoven fabric (4) is composed of flat fibers as described above. The urethane liquid (8) hardly leaks to the surface of the nonwoven fabric (4) because of its low air permeability. Therefore, generation of abnormal noise due to friction with the spring (2) is prevented.
