Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vehicle seat mounting structure, and more particularly to a vehicle seat mounting structure in which a floor panel of a single vehicle is formed of synthetic resin.

(Prior Art) In general, a vehicle seat is disposed on a floor panel, and is usually installed with consideration given to ensuring comfort, safety, etc. of the driver or passenger of the vehicle. As such, for example, Utility Model Application No. 61-734
Publication No. 42 discloses a structure in which a slide frame is fixedly mounted on a floor panel via a bracket, and a seat is mounted on the slide frame so as to be adjustable in its longitudinal position.

(Problem to be solved by the invention) By the way, as a recent trend, many synthetic resin parts are being used in car bodies in order to reduce the weight of vehicles and improve fuel efficiency. It is also being considered that the panels may be made of synthetic resin. However, panels made of synthetic resin have lower rigidity and strength than steel panels, and even if a seat is attached directly to a floor panel made of synthetic resin, the weight of the seat and the burden placed on the seat by the occupants will increase. There is a problem that the floor panel may not be able to withstand the weight of the person.

Therefore, in order to deal with this problem, it may be considered to provide ribs on the floor panel for reinforcement. However, even if you do this, the rigidity and strength of the floor panel itself will only improve; if a sheet is attached to this floor panel,
Since a large load consisting of the weight of the seat and the weight of the occupant is applied to the seat support portion of the panel, the problem remains that the strength of the seat support and support portions may not reach the required strength. .

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve the strength and rigidity of the floor panel itself in a vehicle in which the floor panel is made of synthetic resin, and to ensure the required strength particularly at the seat attachment portion.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized by the following configuration.

That is, in a vehicle in which a floor panel is made of synthetic resin, ribs extending in the vertical and horizontal directions are formed on the floor panel, a boss is provided at the intersection of these ribs, and the seat is attached to the boss. Configure it as follows.

(Function) According to the above configuration, since the floor panel made of synthetic resin is provided with vertical and horizontal ribs, the strength and rigidity of the floor panel itself is strengthened. . In addition, since a boss portion is further provided at the intersection of the vertical rib and the horizontal rib where the strength and rigidity are particularly high, the strength of the intersection is further increased, and the intersection, that is, the boss portion Since the seat is attached to the seat, even if a large load is applied to the seat attachment portion, it can withstand the load sufficiently.

are provided to protrude into the vehicle interior 1, and left and right front seats 6.6 (only one of which is shown) are installed at predetermined positions on the floor panel 2.

The floor panel 2 also includes vertical and horizontal ribs 2b...2b on the back side of the flat part 2a constituting the vehicle floor surface.
2c .
A tunnel portion 2e extending in the front-rear direction is formed in the center of. Then, among the intersections of the vertical and horizontal ribs 2b...2b, 2c...2c provided on the back surface of the floor panel 2, at each of the four intersections located below the sheet 6.6, Boss portions 2f configuring through holes 7 7...
2f are provided respectively.

Next, the structure of the installation of the sheet 6 to the floor panel 2 will be explained with reference to FIGS. 3 to 5.
... Of 2f, two boss parts 2f corresponding to the front and rear
, 2f, two reinforcing plates 8, 8 extending in the front-rear direction are arranged in parallel on the lower surfaces of the two longitudinal ribs 2b, 2b connecting the ribs 2b, 2f. As shown in FIG. 5, these reinforcing plates 8 have a concave cross section so as to cover the ribs 2b extending back and forth from the back side, and have the boss portions 2f, 2f at the front and rear ends. Circular recesses 8a, 8a are formed to cover the recesses 3a, 8a from below, and these recesses 3a,
At the center of 8a, upwardly protruding portions 8b, 8b are formed and project into the through hole 7.7 from below, and furthermore, bolt holes 8c, 8c are formed at the center of these protruding portions 8b, 8b. Weld nuts 9 and 9 are respectively fixed to the lower surfaces thereof.

On the other hand, the seat 6 has two slide members 10.10 fixed to its lower surface attached to two rails 12.12 arranged in parallel on the floor panel 2 via seat brackets 11...11. It is attached so that it can be engaged and slid back and forth. Each of the seat brackets 11 is composed of an upper flange portion 11a, a central vertical portion 11b, and a lower horizontal portion 11c.The flange portion 11a is joined to the lower surface of the rail member 12, and the horizontal portion 11c
A downward protruding portion l is provided at the center of the reinforcing plate 8 so as to correspond to the upward protruding portion 8b formed on the reinforcing plate 8.
