BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of an embodiment for carrying out the present invention, and the parts denoted by the same reference numerals as those in FIGS. 3 to 5 represent the same parts.

The present embodiment relates to a vehicle floor structure in which a vehicle seat adopting a double fold as a storage system is mounted, and a storage hole is provided at an appropriate position on the floor 5 so that the seat belt buckle 3 can be laid down and stored. 6 is opened, and the opening position of the storage hole 6 is set to a closed cross section by the floor reinforcing material 7.

That is, the storage hole 6 of the floor 5 is formed by II in FIG.
-II is defined by a floor reinforcing member 7 having a substantially U-shaped cross-sectional shape (see FIG. 2) when viewed from the direction of the arrow and extending the lower surface of the floor 5 in the vehicle front-rear direction (left-right direction in FIG. 1). It is opened at a position where the closed cross section is opened. Although the floor reinforcing member 7 is illustrated as a longitudinal member extending in the vehicle front-rear direction, it goes without saying that it may be a cross member extending in the vehicle width direction.

Further, in the example shown here, a structure is adopted in which a cover panel 8 forming a recess for accommodating the seat belt buckle 3 is mounted in the storage hole 6, and more specifically, the cover is provided. The outer edge portion of the panel 8 is formed as a flange portion along the lower surface of the outer peripheral portion of the storage hole 6, and the flange portion is fixed to the floor 5.

Here, the seat belt buckle 3 is mounted such that its base end portion is tiltable with respect to the seat belt anchor 9 via a tilt shaft 10. The seat belt anchor 9 is located at the rear portion of the storage hole 6. To the floor 5 immediately after the storage hole 6
It is arranged over the upper surface and is bolted to the floor 5 together with the reinforcing patch 8a integrally formed on the rear flange portion of the cover panel 8.

A seat leg 12 that supports the lower end of the seat back 2 via a tilting shaft 11 is disposed behind the seat belt anchor 9, and the seat leg 12 has the cover. The reinforcing patch 8a integrally formed on the panel 8 is further bolted to the floor 5 together with the reinforcing patch 8b integrally formed on the rear side.

With this structure, when the seat back 2 is laid down and folded forward, the seat belt buckle 3 is pushed down by the seat back 2 and stored in the storage hole 6 of the floor 5. Even if the pocket 4 is not provided in the seat back 2, the interference between the seat back 2 and the seat belt buckle 3 can be avoided.

Therefore, according to the above-described embodiment, the conventional pocket on the side of the seat back 2 is unnecessary, and the appearance of the seat back 2 is not impaired, and the seat back 2 and the seat belt buckle 3 interfere with each other when the seat is stored. Can be surely avoided.

Further, for example, even if an attempt is made to form the storage recess of the seat belt buckle 3 on the floor 5 by sheet metal work, the drawing amount is regulated at each place of the floor 5, and it is difficult to reduce the shape. It is assumed that it is difficult to obtain a storage recess having a size large enough to completely accommodate the seat belt buckle 3, and the storage hole 6 is opened in the floor 5 in this way to store the seat belt buckle 3. According to the method, a sufficient accommodation space can be easily secured without any particular restriction when forming the storage hole 6.

Further, particularly in this embodiment, the storage hole 6
Since the opening position of is set to the closed cross-section portion by the floor reinforcement 7, it is possible to suppress the strength reduction due to the opening of the storage hole 6 in the floor 5 to a minimum, and further, to secure the seat belt buckle 3 Since the cover panel 8 forming a recess that can be accommodated is attached to the storage hole 6, it is possible to substantially completely prevent sound, water, dust, and the like from entering the vehicle interior from under the floor 5, and further, It is possible to prevent a problem that when an object is dropped in the room, the dropped item falls under the floor 5 from the storage hole 6 and cannot be recovered.

Even if the cover panel 8 is not installed in the storage hole 6, if the opening position of the storage hole 6 is set to a closed cross section of the floor reinforcement 7, the sound from the bottom of the floor 5 will be heard. It is possible to reduce intrusion of water, dust, and the like into the vehicle interior as much as possible.

Further, in this embodiment, since the seat belt anchor 9 and the reinforcing patches 8a and 8b of the seat leg 12 are integrally formed in the rear portion of the cover panel 8, the seat belt anchor 9 and the seat leg are formed. The number of parts can be reduced as compared with the case where the twelve reinforcing patches 8a and 8b are formed as separate parts, and the assembling property can be significantly improved.

The vehicle floor structure of the present invention is not limited to the above-described embodiment, and the cover panel does not necessarily have to be integrally formed with reinforcing patches for both the seat belt anchor and the seat leg. Needless to say, it is only necessary that the reinforcing patch of the seat belt anchor is integrally formed, and in addition, various changes can be made without departing from the scope of the present invention.
