Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat body mounting structure that is applied to attach and fix a seat body consisting of a cushion foam and a seat skin to a bottom plate.

Conventionally, when constructing various types of sheets, a cushion foam formed into a predetermined shape is placed on a bottom plate, and then a sheet skin covering the cushion foam is applied, and the skin is While adjusting the tensioning state, the terminal is rolled inward from the edge of the bottom plate and fixed by driving with a tack or the like. However, this assembly work is done entirely by hand and is extremely time-consuming, and it also requires considerable skill and skill to ensure that the seat skin is evenly covered all around. is needed.

An object of the present invention is to provide a mounting structure for a sheet body that is ingeniously devised to eliminate such drawbacks.

That is, in the mounting structure of the seat body according to the present invention, the entire cushion form is covered with the seat skin, and the cushion form and the seat skin are made to partially protrude so that projections are placed at appropriate locations on the bottom surface. The protrusions of this sheet body are fitted into the openings formed in the plate surface of the bottom plate to protrude to the back side, and the tip end of the protrusion is fixed to the back side of the bottom plate to form a sheet. It is constructed by attaching the body to the bottom plate.

This will be explained below based on the illustrated embodiments.

In this embodiment, a sheet body A having a predetermined shape is constituted by a cushion foam 1 made of two resin foams and a sheet skin 2 molded to cover the entire cushion foam 1. This sheet body A is
It can be formed by simultaneously molding the cushion form 1 and the seat skin 2 using a mold. In addition, the cushion foam 1 and the seat skin 2 can be integrated into one by forming the seat skin 2 separately into an upper and a lower part, or by forming the cushion foam 1 by stacking several layers and sewing the seat skins together. It is also possible to form the sheet body A into a cushion form 1.
It is sufficient if they are integrally molded by covering the entirety with the sheet skin 2.

A plurality of dowel-shaped protrusions 3, 3, . . . are provided on the bottom surface of the sheet body A at about four locations on the front, rear, left and right sides. These protrusions 3, 3... are formed by partially protruding the cushion form 1 and the seat skin 2 during mold molding, and since they are solidly formed from the cushion form 1, they are elastic and expandable. It's summery. The bottom plate B has a planar space that can receive the bottom surface of the sheet body A over almost the entire surface,
Upright flanges b ₁ and b ₂ are provided on the left and right sides in the longitudinal direction, so that the sheet body A can be supported to prevent it from spreading. Also, on the plane, sheet body A
Openings 4, 4... are provided at positions corresponding to the protrusions 3, 3... formed on the bottom surface.

For this bottom plate B, sheet body A
is mounted, and the protrusions 3, 3... on the bottom surface thereof are inserted into the openings 4, 4... on the plate surface. When assembling the seat body A, since the seat body A is previously formed into a predetermined shape, the attachment state can be regulated by the bottom frame. In addition, when inserting and inserting the projections 3, 3, etc., the cushion form 1 can be easily inserted by reducing and deforming, and after insertion, the sheet body A is elastically expanded, so that the sheet body A can be inserted into the bottom plate B.
Temporary fixing can be determined individually. In order to integrally attach this sheet body A to the bottom plate B, the opposing surfaces may be bonded together with adhesive, and the tip ends of the protrusions 3, 3, etc. may be pressed against the back side of the bottom plate B. It is also possible to fix it with hooks 5, 5 protruding from the back surface of the bottom plate B (see Figures 1 and 2). Instead of that hook 5, 5, tatsuker 6,
6 can also be used, in which case protrusions 3, 3
It is only necessary to apply the pressed edge of the tip to the back surface of the bottom plate B and drive the tassels 6, 6 into the bottom plate B (see Fig. 3). Also,
The protrusions 3, 3... can cut off the seat skin 2 to expose the cushion form 1, and the cushion form 1 may be configured to allow air to enter and exit freely. In this case, the cut end of the seat skin 2 can be fixed to the bottom plate B with hooks 5, 5 or tassels 6, 6 (fourth
(see figure).

In the seat body mounting structure configured in this way,
In order to form a sheet body A having a certain shape by applying the seat skin 2 to the entire cushion form 1 in advance, the sheet body A is placed on the plane of the bottom plate B, and the protrusions 3, 3... into the openings 4, 4... of the bottom plate B, and the seat body A can be mounted and positioned on the bottom plate B by simply inserting them. Further, since the seat skin 2 is also present on the contact surface of the bottom plate B, the seat body A can be fixed to the bottom plate B using the bottom surface or the protrusions 3, 3, . . . There is no need to perform upholstery work on the seat skin.

As described above, according to the seat body mounting structure according to the present invention, various seat assembly operations can be performed extremely easily, and the degree of tensioning of the seat skin can be maintained constant over the entire circumference.
