Description

[Detailed Description of the Invention] The present invention relates to a seat suitable for equipping special vehicles such as motorcycles, tillers, and automatic lawn mowers.

Generally, when constructing this type of seat, a cushion foam previously formed into a predetermined shape is placed on a bottom plate, and then a sheet skin covering the cushion foam is applied. Normally, the terminal is rolled inward from the edge of the bottom plate while adjusting the tensioned state, and secured with a fastening member such as a tassel. However, this not only requires a great deal of time and effort to assemble each member, but also requires a skilled technique since the seat skin must be evenly stretched over the entire circumference.

Conventionally, in order to simplify the assembly, a convex part and a convex edge were provided on the mating surface of the cushion body, which covers the cushion form with the seat skin, with the seat frame, and a convex part was placed on the back of the seat frame in a corresponding position. The cushion body can be attached by protruding it and abutting it against the body side.
No. 42764). However, with this seat, the cushion body is fixed simply by bringing the protrusions and protruding edges protruding from the back of the seat frame into contact with the body side and crushing them. There is a risk that the seat frame may fall out of the hole or recess of the seat frame. In particular, seats for motorcycles do not have a structure that comes into contact with the back side of the bottom plate, and the cushion form is relatively thin, so it is difficult to fit protrusions into holes in the bottom plate. It is not possible to securely fix the cushion body to the bottom plate just by aligning them together, and since the entire cushion form is covered with the sheet skin, air cannot be taken in and out, so the amount of deflection of the cushion form is small and the cushion is not easily fixed. There is no escaping the fact that one is inferior to one's sex.

An object of the present invention is to provide an improved seat that can be easily and securely assembled to a bottom plate even in a relatively flat cushion body such as one for a two-wheeled vehicle, and exhibits good cushioning properties.

That is, in the seat according to the present invention, a protrusion is provided by partially protruding from the bottom surface of a cushion body in which substantially the entire cushion form is covered with a seat skin, and the cushion body is placed on a bottom plate to form a protrusion. The end of the seat skin separated from the cushion foam is placed on the tip end side of the protrusion exposed through the hole and is fitted into the hole formed in the flat surface of the bottom plate, and the end of the seat skin separated from the cushion foam is applied to the back surface of the bottom plate and fixed with a stopper member. The cushion form is partially exposed on the back of the bottom plate to allow air to flow in and out.

This will be explained below based on the illustrated embodiments.

The cushion body A shown in FIG. 1 is formed to have a fixed shape by integrally molding a cushion foam 1 made of a single resin foam and a sheet skin 2 that covers almost the entire cushion foam. This cushion body A can be formed by simultaneously molding the cushion form 1 and the seat skin 2 using a mold. Further, the seat skin 2 can be formed separately into an upper side and a lower side, or the cushion form 1 can be formed by stacking several layers, and these can be formed by integrating them by stitching between the skins.

On the bottom surface of the cushion body A, a plurality of dowel-like protrusions 3, 3, . . . are provided at about four locations on the front, back, left and right sides. These protrusions 3, 3... can be formed by partially protruding the cushion form 1 and the seat skin 2 during mold molding, and since the cushion form 1 is solid, it is elastic and expandable. It's getting old. The bottom plate B has a planar space that can receive and place the bottom surface of the cushion body A over almost the entire surface thereof, and has rising flanges on the left and right sides in the longitudinal direction to support the cushion body A so as to prevent it from spreading. You can also do it. The plane has openings 4 into which the protrusions 3, 3... can be fitted at positions corresponding to the protrusions 3, 3... formed on the bottom surface of the cushion body A.
4... are provided. The cushion body A is placed on the bottom plate B, and the cushion body A is assembled by fitting and inserting the projections 3, 3, . . . on the bottom surface into the planar openings 4, 4, . At this time, the protrusions 3, 3... can be easily inserted into the openings 4, 4... of the bottom plate B by the reduction deformation of the cushion form 1, and after insertion, they bulge out somewhat due to elasticity. The cushion body A and the bottom plate B may be bonded together between their opposing surfaces with an adhesive. The seat skin 2 is separated from the cushion form 1 at the tip sides of the protrusions 3, 3, . The cushion body A is attached by applying it and fixing it with stop members 5, 5 such as tassels or hooks.

In the seat configured in this way, the protrusions 3, 3... of the cushion body A are connected to the holes 4, 3, etc. of the bottom plate B
Not only can the cushion body A of a certain shape be positioned and assembled to the bottom plate B by simply inserting it into the bottom plate B, but also the seat skin 2 covers almost the entire cushion form 1. Even if the skin 2 is not stretched, it can be firmly attached with appropriate tension by separating the ends of the protrusions 3, 3... and fixing the ends of the seat skin 2 to the bottom plate B with the fastening members 5, 5. can. Also, on the back side of the bottom plate B, there are openings 4, 4...
Since a part of the cushion form 1 is exposed through the cushion and air can be taken in and out from that part, the cushion form 1 can be greatly flexed and deformed in response to the load of the seater, thereby exhibiting good cushioning properties. It becomes like this.

As described above, according to the seat according to the present invention, the work of assembling the cushion body is extremely easy, and the degree of upholstery of the seat skin can be maintained constant over the entire circumference, and it can be installed securely. Furthermore, by allowing air to freely flow in and out of the cushion foam, cushioning performance can be improved.

Claims (1)

[Scope of utility model registration request] A protrusion is provided by partially protruding from the bottom surface of a cushion body in which almost the entire cushion form is covered with a seat skin, and the cushion body is placed on a bottom plate, and the protrusion is formed into a hole formed in the flat surface of the bottom plate. The end of the seat skin separated from the cushion foam is placed on the back side of the bottom plate on the tip end side of the protrusion exposed from this opening, and fixed with a stopper member, and the cushion foam is connected to the air outlet.
