Description

[Detailed explanation of the idea] The present invention relates to a seat for a vehicle or the like.

As shown in FIG. 1, in a seat, particularly a vehicle seat 1, recesses 2 of various shapes are formed in the seat surface from the viewpoint of comfort and design.

This recess is formed by suspending and bonding the seat skin to the seat pad within the seat.

In this case, the hanging and binding is carried out by using a special means such as a so-called insert wire embedded in the seat pad, a spring, etc., and suspending and binding the skin from this.

Similarly, the seat skin is wrapped around and secured to the seat pad by, for example, tying the periphery of the seat skin to an insert wire or the like provided on the seat pad so that the skin tightly covers the surface of the seat pad. ing.

An example of a conventional vehicle seat will be described with reference to FIG. 2. In the figure, numeral 3 indicates a seat pad, and numeral 4 indicates its skin.

The seat pad 3 is made of a foam molded body of a resin material such as urethane, and at the same time as this molding, a notch 5 is formed at a portion where the seat is suspended to form the recess 2 in the seat surface.

A wire 6 is embedded in this notch 5.

On the surface 3a of the seat pad 3 on the side forming the seat surface, for example, an inner lining 4a and an outer lining 4 forming part of the outer skin 4 are disposed.
A seat skin portion consisting of a relatively hard elastic sheet 7 sandwiched between portions b is covered, and a so-called hanging bag 8 is sewn to the portion corresponding to the notch 5 at the position indicated by number a.

This hanging bag 8 is made of a piece of cloth that is folded in half and its both edges are sewn to the seat skin, and a wire 9 is passed through the folded portion as shown in FIG. By inserting and wrapping the hog rings 10, they are locked together and the skin 4 is suspended and tied.

On the other hand, a wire 11 is inserted into the periphery of the seat skin 4, and this wire 11 is similarly secured and tightened to a wire 12 embedded in the periphery of the seat pad 3, for example, the lower surface, by winding a hog ring 10 around it.

In this way, in a normal seat, hanging binding is used to form a recess of a desired shape in the part of the skin, especially the part that becomes the seat surface, and the fixing of the skin to the seat pad is done using, for example, a method embedded in the seat pad. It is secured to the wire with a hog ring.

However, the work of inserting and locking the hog ring 13 into the wire embedded in the seat pad in this way is extremely complicated.

The present invention provides a seat for a vehicle, etc., in which the above-mentioned recess can be formed on the seat surface by, for example, hanging and tightening the seat surface easily. be.

An example of the present invention will be described with reference to FIG. 4. In FIG. 4, parts corresponding to those in FIGS. 1 to 3 are designated by the same reference numerals, and redundant explanation will be omitted.

In the present invention, in particular, when molding the seat pad 3, that is, when foam molding it, the constituent material of the seat pad, that is, urethane resin, is applied to the surface opposite to the surface 3a that forms the seat surface. A sheet body to be impregnated, for example, a fixed sheet 14 embedded with gold mine and integrated with the seat pad 3
Configure.

In this way, the adhesive sheet 14 impregnated with resin is
This creates a strong sheet with plenty of rigidity.

This fixed sheet 14 has, for example, a bent portion 1 on its periphery.
4a, and a part thereof is provided with a strip-shaped tongue piece 15 as shown in FIG. 5 or a plurality of cut and raised tongue pieces 15 as shown in FIG. It penetrates through the inside and exposes the suspension notch 5 on the seat surface provided in the pad 3.

And the tongue piece 15 of the sheet 14 facing into the notch 5 of the pad 3
For example, a plurality of hog rings 5 are inserted and wound around the wire 9 in the hanging bag 8 so as to bend the tip of the hog ring 5 and the wire 9 in the hanging bag 8 is engaged.

On the other hand, the wire 11 wrapped around the periphery of the skin 4 is wound around the periphery of the fixing sheet 14, and the hog ring 13 is similarly inserted and engaged to bring the skin 4 into close contact with the surface of the pad 3.

According to the above-mentioned configuration of the present invention, in the work of covering and binding the skin to the pad, especially in the work of securing the skin and suspending the skin to form a recess on the seat surface, the adhesive that serves as the suspension binding part of the skin is used. The upper end of the cut and folded part of the sheet is exposed to the outside of the bat, allowing the operator to see it directly, compared to the case where the worker wraps the hog ring around the wire embedded in the pad. The work becomes extremely simple, the work efficiency is significantly improved, and the skin is securely adhered to the pad, resulting in an extremely good finished appearance.

Further, since the fixing sheet 14 can be formed at the same time as the pad 3 is molded, the number of man-hours does not increase due to the provision of the fixing sheet 14, and the benefits of the fixing sheet 14 are enormous in practical use.
