Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat mounting structure mounted on an upper surface of a floor of an automobile or the like via an engaging member and an engaging member.

2. Description of the Related Art As a conventional mounting structure for a vehicle seat of this kind, for example, a structure described in Japanese Utility Model Publication No. 1-150508 is known.

In brief, the hook mail, which is an engaging member attached to the mounting hole of the floor panel, is formed of a synthetic resin material and has a fitting member having a long hole in a direction perpendicular to the shaft, and an upper surface of the fitting member. It becomes a seat portion, a main body having a fitting shaft on the lower surface of the seat portion, a flat head portion having a larger diameter than the shaft diameter on the head portion, and the fitting member and the main body are formed at the hole edge of the mounting hole. And a pin member that is integrally fixed. On the other hand, the hook member, which is an engagement member attached to the mounting hole of the floor sheet, has a circular head, a neck at the lower end of the head, and a neck that engages with the mounting hole, and is provided at a lower end of the neck. And a stem portion having a substantially horizontal C-shaped cross section and having an opening ring fitted on the head of the fitting member on the inner periphery of the lower end.

Then, the hook mail is inserted into the mounting hole of the floor panel at the same time that the fitting member, the main body, and the pin member are assembled, and mounted on the edge of the hole. On the other hand, the floor sheet to which the hook mail is attached in advance is placed on a predetermined upper surface of the floor panel, and each hook mail is pushed from above in accordance with the corresponding hook mail to lock the two together. here,
If the center positions of the hook mail and the hook mail do not match, the fitting member is slid in the diametric direction via the long hole to adjust the positional deviation and match the relative position to attach the floor sheet. It is designed to make work easier.

Problems to be Solved by the Invention However, in the conventional seat mounting structure,
Since the relative positions of the hook mail and the hook mail are adjusted using the mobility of the hook mail on the floor panel side, such a position adjustment operation is extremely difficult. That is, since the hook mail cannot be seen from the outside at the time of position adjustment, the entire floor sheet must be moved to adjust the approximate relative position of the hook mail and the hook mail first after the floor mat is put on. In addition, even when the relative position is finely adjusted by sliding the hook mail after the completion of such a rough relative position adjustment, the entire floor sheet may have to be moved. Therefore, the efficiency of the floor sheet mounting operation is reduced.

In addition, since the fitting member merely slides only in the determined diameter direction via the long hole, when the entire floor sheet expands and contracts in a free direction due to the thermal influence of the vehicle,
The fitting member cannot follow the expansion and contraction movement, and free deformation of the floor sheet is regulated around the hook mail, and there is a possibility that distortion or wrinkles may occur.

Means for Solving the Problems The present invention has been devised in view of the above-mentioned conventional problems, and in particular, for example, a flexible portion having a bent cross-sectional shape is integrally formed around an engaging member of a vehicle body floor sheet, for example. It is characterized by doing.

Operation According to the above configuration, for example, when the floor sheet is attached, the floor sheet is put on the predetermined position on the upper surface of the floor panel. Here, when the center positions of the engaging member and the engaging member do not match each other, the entire floor sheet is not moved, and only the engaging member is moved freely in the radial direction via the flexible portion. To the center position of. That is, the position can be adjusted by freely moving the engaging member. Therefore, the work of attaching the floor sheet becomes extremely easy.

Moreover, even if the floor sheet expands and contracts due to heat after the two members are engaged, the flexible portion absorbs and allows the thermal deformation, so that distortion and the like of the floor sheet are prevented.

Examples Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

1 to 3 show one embodiment of a seat mounting structure according to the present invention. In the drawings, reference numeral 1 denotes a hook mail as an engaging member mounted on a floor panel 2 of a vehicle body, and 3 denotes vacuum forming or hot pressing. A hook female as an engaging member attached to a vinyl chloride floor sheet 4 integrally formed by molding, wherein the hook male 1 is a synthetic resin that is engaged with an edge of the mounting hole 2a of the floor panel 2. It is composed of a main body 1a of a material and a pin member 1c for press-fitting into the central hole 1b of the main body 1a to expand the main body 1a in the radial direction.

On the other hand, the hook female 3 has the same configuration as the conventional one, and has a circular head 3a and a mounting hole formed at a lower end of the head 3a and drilled at a predetermined position of the floor sheet 4. 4a, a stem 3b provided at the lower end of the neck 3b, and a stem 3c having a substantially horizontal C-shaped cross section. An opening ring 3d fitted on the bulging head of 1a is provided.

In the floor sheet 4, a flexible portion 5 is formed around the mounting hole 4a, that is, around the hook female 3. The flexible portion 5 is formed in a ripple shape around the hook female 3, and the upper and lower end portions 5a and 5b are formed in an arc-shaped cross section (bent cross-sectional shape) so as to facilitate bending deformation. Therefore, it is formed to be able to bend and deform in any radial direction of the whole.

Therefore, according to this embodiment, when the floor sheet 4 is attached to the floor panel 2 of the vehicle body, the floor sheet 4 is first put on the upper surface of the floor panel 2 at a predetermined position. Here, when the center positions of the hook mail 1 and the hook mail 3 do not coincide, the floor sheet 4 is not moved in its entirety, and only the hook mail 3 is held and freely moved in the radial direction via the flexible portion 5. Move to match the center position of hook mail 1. That is, as shown in FIG. 4, the hook mail 3 can be freely moved in any radial direction to adjust the position relative to the hook mail 1. Thereafter, when the hook ring 3 is pressed from above and the opening ring 3 d is fitted to the head of the main body 1 a of the hook mail 1, the floor sheet 4 is securely attached to a predetermined position on the upper surface of the floor panel 2. Therefore, the work of attaching the floor sheet 4 becomes extremely easy.

In addition, even if the floor sheet 4 expands and contracts due to thermal influences after the floor sheet 4 is attached, the deformation is absorbed through the flexible portion 5 to allow the deformation movement. The occurrence of distortion, wrinkles, and the like of the floor sheet 4 due to the movement restriction of the mail 3 is reliably prevented.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the upper and lower ends 5a and 5b of the flexible portion 5 are bent in a rectangular shape. Therefore, in this embodiment, the upper and lower ends 5a, 5b
Bends around the periphery of the, relatively easy bending deformation can be obtained.

FIG. 6 shows a third embodiment of the present invention, in which the lower end portion 5b of the flexible portion 5 is bent in a substantially V-shape, and in this case also, the lower end edge becomes a fulcrum and is bent and deformed. Therefore, the bending deformation is further facilitated.

FIG. 7 shows a fourth embodiment of the present invention, in which a flexible portion 5 is formed in a stepped shape from the hook female 3 to the outer periphery, and a felt portion 6 is formed on the lower surface of the floor sheet 4 other than the flexible portion 5. Are provided integrally. In this manner, by forming the flexible portion 5 in a step shape, the entire flexible portion 5 is easily deformed flexibly in the vertical and radial directions, so that the mobility of the hook female 3 is further improved.

Further, the heat transfer from the floor panel 2 to the floor sheet 4 is cut off by the felt portion 6, and the thermal deformation of the floor sheet 4 is controlled.

The present invention is not limited to the configuration of the above-described embodiment. The cross-sectional shape of the flexible portion 5 can be further changed, and the configurations of the hook mail 1 and the hook mail 3 are also arbitrarily changed. It is possible to

Further, in each of the embodiments, the case where the present invention is applied to the floor sheet of the vehicle body is shown. However, the present invention is not limited to this and can be applied to other seats and the like.

Advantageous Effects of the Invention As is clear from the above description, according to the seat mounting structure of the present invention, a flexible portion having a bent cross-sectional shape is formed integrally around the engaging member of the sheet, especially when the seat is mounted. In order to align the center positions of the engaging member and the engaging member, the operator visually checks the position of the engaging member from the upper surface side of the sheet while using only the engaging member by utilizing the bending deformability of the flexible member. The relative position can be adjusted by freely moving in any direction. Also, when engaging the engaging member and the engaging member, the engaging member can be easily pushed in the axial direction by utilizing the characteristics of the flexible member having the bent cross-sectional shape.
Therefore, the work of mounting the seat is extremely easy, and the efficiency of the mounting work can be improved.

In addition, even when the sheet is expanded and contracted due to thermal influence, the flexible portion allows the thermal deformation to be absorbed.
The occurrence of sheet distortion and wrinkles is prevented.
