Description

[Detailed description of the invention] (Industrial application field) This invention is applicable to vehicle seats such as automobiles,
Specifically, the width of the body part is constant, the frame part is sewn on both sides of the body part, and the seam allowance is an outer skin that protrudes to the back side, and the outer skin is covered with this skin and is spaced at intervals equal to the width of the body part. This invention relates to an improvement in a vehicle seat comprising a foam part having a groove on its surface into which the seam allowance is inserted.

(Prior art) Conventionally, this type of sheet is made by inserting the seam allowance between the body part and the frame part in the outer skin into the concave groove of the part.
The seam allowance prevents protrusions from protruding onto the surface of the epidermis.

By the way, in a seat bag A shown in FIG. 6, for example, in which decorative vertical patterns A, I, etc. are arranged vertically on the body part 1a of the outer skin 1, the overall width L of the body part 1a is is formed in a constant manner. Therefore, there are frame parts 1 on both sides of this body part 1a.
When b and 1b are sewn together to form the outer skin 1, seam allowances RO and RO are created at the ends of both parts, but the distance between these left and right seam allowances RO and RO is also constant. In the figure, 1c is the gusset part.

On the other hand, the foam parts 2 covered with the outer skin 1 are provided with spaces equal to the width of the body part 1a so that the left and right seam allowances protruding from the back side of the outer skin 1 can be inserted into the surface of the foam parts 2. Concave grooves 21, 21 are provided with openings. Note that the grooves 21, 21 are recessed in a substantially U-shape.

When the seat bag A is assembled by covering the surface of the pad 2 with the skin 1, the structure will be as shown in FIGS. 8 to 10.

That is, the hanging cloth 5 is sewn to the body part 1a of the outer skin 1, and the part where the body part 1a is suspended by the hanging cloth 5 has a seam allowance R in the grooves 21b, 21b, as shown in FIG.
However, in the upper part, the seam allowances R and R are shifted to the outside of the concave grooves 21c and 21c, as shown in FIG. 9, and in the lower part, as shown in FIG. There is a problem that it cannot be inserted into the grooves 21c, 21c... This is the concave groove 21
The surface of the pad 2 between c and 21c is flat, and the body part a is pulled left and right, so it becomes as shown in Fig. 9. Further, as shown in FIG. 8, grooves 21a, 2
This is because when the surface of the pad 2 between the parts 1a is uneven, the body part 1a is drawn inward by the difference in level between the unevenness.

In the figure, reference numeral 3 indicates a frame, and reference numeral 4 indicates a spring member such as an S spring that supports the pad 2.

(Effects) The present invention solves the above-mentioned problems in the conventional products, namely, in a vehicle seat where the width of the body part of the outer skin is constant and a groove is formed on the surface of the part to insert the seam allowance between the body part and the frame part. The entire seam allowance is inserted into the groove, and the purpose is to prevent protrusions from occurring on the surface of the skin due to the seam allowance.

(Structure) Therefore, the present invention is characterized in that the groove of the part is formed with an enlarged opening on one side, and the part surface between the left and right grooves is flat. In this case, the opening of the concave groove is formed in an enlarged shape toward the outside of the part, and if the part surface between the left and right concave grooves is uneven,
The opening of the groove is cut out in an enlarged manner toward the inner side of the part.

Therefore, by forming the opening of the concave groove in this enlarged shape, the seam allowance of the outer skin is inserted into the concave groove, so that no protrusion is generated on the surface of the outer skin due to the seam allowance as in the conventional product.

(Example) An example of the present invention will be described based on FIGS. 1 to 5.

Fig. 1 shows a part 2 used in the present invention, in which grooves 2 are bored at intervals L equal to the width of the body part 1a, as in the conventional part. The groove 21a' above the position where the hanging cloth 5 is provided is formed as shown in FIG. That is, the groove 21a' is cut out in an enlarged manner outward by an angle θ relative to the conventional groove 21a.

Further, as shown in FIG. 5, the lower groove 21c' is enlarged inward by an angle θ relative to the conventional groove 21c.

That is, since the openings of the grooves 21c' and 21a' are cut out wider than those of the conventional product, the openings of the grooves 21c' and 21a' are wider than those of the conventional product.
As shown in FIG. 3, the seam allowances of the body portion 1a and the frame portion 1b of the outer skin 1 are inserted into grooves 21a' and 21a' having enlarged openings, respectively.

Note that the grooves 21b, 21b into which the seam allowances on both sides of the hanging cloth 5 are inserted are formed in a substantially U-shape as in the conventional product.

The outer skin 1 covering the pad 2 has a body portion 1a, frame portions 1b, 1b, and gusset portions 1c, 1c sewn in the same manner as in the past.

Therefore, the present invention can be obtained by making wide notches on the inside or outside of the concave groove 21 provided in the conventional part 2 at the portions 21a and 21c.

In FIGS. 1 to 5, the same reference numerals as in FIGS. 6 to 10 indicate the same members.

(Effects) As mentioned above, the present invention simply cuts out one side of the opening in the concave groove of the part in an enlarged shape, so that the seam allowance between the body part of the outer skin and the frame part becomes an enlarged concave groove. inserted into.

Therefore, unlike the conventional products, the seam allowance does not protrude from the concave groove of the padding, causing protrusions on the surface of the outer skin, or the body part of the outer skin does not come into close contact with the surface of the padding and rises. Therefore, it is possible to provide a vehicle seat that has a better appearance and constant quality than conventional products.
