Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a seat whose seat portion is configured to be freely ventilated as a measure to prevent stuffiness.

Prior Art In constructing this type of seat, it is conceivable to apply a highly breathable non-woven fabric to a portion corresponding to the seat portion during foam molding of the cushion pad and foam mold it integrally.

However, in this case, a large amount of foamed resin such as urethane that forms the cushion pad impregnates the nonwoven fabric, which causes the nonwoven fabric to lose its breathability, and also hardens and impairs the cushioning properties of the sheet. .

Problems to be Solved by the Invention The object of the invention is to provide a breathable seat that can maintain good cushioning properties and provide sufficient ventilation to the seat surface, and can be easily assembled.

Means for Solving the Problems In the breathable sheet according to the present invention, a thick breathable non-woven fabric made of a weldable material is interposed between the breathable skin material and at least a portion corresponding to the seating surface of the cushion pad. A backing material made of a material that can be welded to the back side of the cushion pad is provided, and a skin material and a nonwoven fabric that are partially invaginated from the suspension hole of the cushion pad to the back side of the cushion pad are welded and fixed to the backing material. It is assembled by

Function: In this breathable sheet, a breathable non-woven fabric is interposed between the upholstery material and at least a portion of the cushion pad that corresponds to the seat surface. Not only can breathability be imparted, but since the nonwoven fabric is thick, it maintains good cushioning properties together with the cushion pad, and the skin material and the nonwoven fabric can be inserted into the back side of the cushion pad through the hanging hole of the cushion pad. By welding and joining the backing material to the backing material, the skin material is suspended and fixed, so the three parts can be assembled together extremely easily.

Embodiments The following description will be made with reference to the accompanying drawings.

The illustrated embodiment is a case where a vehicle seat is constructed, and the seat cushion of the seat cushion is provided with breathability. As shown in FIG. 1, this seat cushion has a breathable nonwoven fabric 3 interposed between a skin material 1 and at least a portion corresponding to the seat surface of a cushion pad 2, and a backing material 4 between the skin material 1 and the nonwoven fabric 3. and the hanging part 5 of the skin material 1
It is assembled by welding and joining.

As the skin material 1, a breathable fabric such as a woven fabric, a non-woven fabric, or a knitted fabric is used, and the cushion pad 2 is made of foamed resin such as urethane. As the nonwoven fabric 3, it is preferable to use a polyester nonwoven fabric that can be welded by welding.
g/m ² and a thickness of about 10 to 17 mm, preferably 15
It is best to use a thick one with a thickness of mm. Similarly, the backing material 4 is made of a material that can be welded such as polyester nonwoven fabric.

To assemble a seat cushion from each of these members, the skin material 1 and the nonwoven fabric 3 are stacked one on top of the other and covered with the cushion pad 2.
The skin material 1 and the nonwoven fabric 3 are partially invaginated on the back side of the cushion pad 2 using a welder type through the hanging hole 6 formed through the thickness direction of the cushion pad 2, and the backing material prepared in advance on the back side of the cushion pad 2 is inserted. 4 to press it into contact. As a result of this pressure welding, the nonwoven fabric 3 and the backing material 4 are melted and welded to each other, and the skin material 1 is impregnated with the melted portion of the nonwoven fabric 3, so that the three materials including the nonwoven fabric 3 and the backing material 4 are welded together. It becomes fixed. If a welding member such as a polyester film is laminated to at least the suspended portion of the skin material 1, the skin material 1, the nonwoven fabric 3, and the backing material 4 can be welded together more reliably.

In addition, other than the hanging portion of the nonwoven fabric 3, the front end portions 3a and 3b can be fixed with double-sided tape 7 as shown in FIG. Further, in order to save the labor required for this attachment, the one end side 3a can be attached in advance by impregnating it with a foamed resin during foam molding of the cushion pad 2.

In a seat constructed in this way, sufficient air permeability can be imparted to the seat surface of the seat because it is interposed between the skin material 1 and the portion of the cushion pad 2 corresponding to the seat surface by making use of the breathable property of the nonwoven fabric 3. Furthermore, since the nonwoven fabric 3 is thick, it can maintain good cushioning properties together with the cushion pad 2. In addition, since the nonwoven fabric 3 is hung together with the seat skin 1, it can not only be interposed between the seat skin 1 and the cushion pad 2 to prevent it from shifting, but also the hanging portion 5 can be beautifully shaped as shown in FIG. Each member can be easily assembled without requiring hanging members such as a hanging bag, a resting wire, or a C-shaped ring.

In addition, although the above-mentioned embodiment illustrated a seat cushion, it can be similarly applied to constructing a seat bag, and can also be applied to assembling furniture seats other than those for vehicles.

Effects of the Invention As described above, the breathable sheet according to the present invention can be easily assembled, provides sufficient breathability, and maintains good cushioning properties.
