DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle floor structure.

[0002]

2. Description of the Related Art Conventionally, seats in a third row of a one-box car and seats in a second row of a two-box car have been provided with the configuration shown in FIG.
As shown in FIG. 4, the seat cushion 1 is raised from the front end side (left side in the figure) as a base point and the rear end side (right side in the figure) is raised, and then the seat back 2 is moved forward. There is a storage type called a double fold, in which a luggage compartment at the rear of the vehicle can be expanded by folding down and folding.

When such a double fold is employed, in order to prevent the seat back 2 and the seat belt buckle 3 from interfering with each other when the seat is stored, the seat belt buckle 3 is twisted up and down in a vertically tiltable structure. The urging means such as a spring always urges the user to stand up to the upper use position, and the pocket 4 is recessed at a position corresponding to the seat belt buckle 3 in the seat back 2, and the seat back 2 is moved forward. The seat belt buckle 3 is accommodated in the pocket 4 when it is turned down.

[0004]

In such a conventional structure, however, as shown in FIG.
In the normal use state in which the pocket 4 is
However, there is a problem in that it looks like a large hole opened in the seat back 2 and the appearance is significantly impaired.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to prevent interference between a seat back and a seat belt buckle during storage of a seat without impairing the appearance of the seat back. I do.

[0006]

SUMMARY OF THE INVENTION The present invention is configured so that a seat back is folded down by laying down on the front with a seat cushion standing upright, and a seat belt buckle can be tilted beside the seat back. A vehicle floor structure including a mounted vehicle seat, wherein a storage hole is opened at an appropriate position on the floor so that a seat belt buckle can be folded down and stored.

[0007] According to this structure, when the seat back is laid forward and folded down, the seat belt buckle is pushed down by the seat back and stored in the storage hole of the floor, so that a pocket is provided in the seat back. Even if it is not recessed, interference between the seat back and the seat belt buckle can be avoided.

Further, in the present invention, the opening position of the storage hole is preferably set to a closed cross-section by the floor reinforcing material, and in this case, the strength reduction due to the opening of the storage hole in the floor is minimized. In addition, entry of sound, water, dust, etc. from under the floor into the vehicle interior is reduced.

Further, in the present invention, it is preferable that a cover panel forming a concave portion capable of accommodating a seat belt buckle is mounted in the storage hole, so that a vehicle such as a sound, water, dust or the like from below the floor can be provided. It is possible to almost completely prevent intrusion into the cabin, and when objects are dropped in the cabin, there is a problem that the dropped items fall down from the storage hole to the floor and cannot be collected. Is prevented.

In addition, it is preferable that at least a reinforcing patch for the seat belt anchor is integrally formed on the cover panel. In this case, the reinforcing patch for the seat belt anchor is compared with a case where the reinforcing patch is formed as a separate part. Thus, the number of parts can be reduced, and the assemblability can be improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention, in which the same reference numerals as in FIGS. 3 to 5 denote 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 stored in a folded state. 6, and the opening position of the storage hole 6 is set to a closed cross section by the floor reinforcing member 7.

That is, the storage hole 6 of the floor 5 is
-II Defined by a floor reinforcing member 7 having a substantially U-shaped cross-sectional shape (see FIG. 2) as 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 to open the closed cross section. Although the floor reinforcing member 7 is illustrated as a longitudinal member extending in the vehicle front-rear direction, it is needless to say that a cross member extending in the vehicle width direction may be used.

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

Here, the seat belt buckle 3 is attached at its base end to a seat belt anchor 9 via a tilt shaft 10 so as to be tiltable. From 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 flange portion behind the cover panel 8.

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

Thus, with this configuration, when the seat back 2 is folded down by falling 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 recessed in the seat back 2, interference between the seat back 2 and the seat belt buckle 3 is avoided.

Therefore, according to the above embodiment, the pocket on the side of the seat back 2 unlike the related art is not required, and the interference between the seat back 2 and the seat belt buckle 3 when the seat is stored without impairing the appearance of the seat back 2. Can be reliably avoided.

Further, for example, even if an attempt is made to form the storage recess of the seatbelt buckle 3 on the floor 5 by sheet metal work, the amount of drawing is regulated for each location of the floor 5 and it is difficult to form and 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, but the storage hole 6 is opened in the floor 5 to store the seat belt buckle 3. If it is a system, when forming the storage hole 6, a sufficient accommodation space can be easily secured without any particular restriction.

In this embodiment, in particular, the storage hole 6
Is set to the closed cross-section by the floor reinforcing member 7, so that the strength reduction due to the opening of the storage hole 6 in the floor 5 can be suppressed to a minimum, and the seat belt buckle 3 Since the cover panel 8, which forms a recess that can be accommodated, is mounted in the storage hole 6, sound, water, dust and the like from under the floor 5 can be almost completely prevented from entering the vehicle interior. When an object is dropped indoors, it is possible to prevent a problem that the dropped object falls below the floor 5 from the storage hole 6 and cannot be collected.

Even if the cover panel 8 is not attached to the storage hole 6, if the opening position of the storage hole 6 is set to the closed cross section by the floor reinforcing member 7, sound from below the floor 5 can be obtained. It is possible to minimize intrusion of water, dust and the like into the vehicle interior.

In this embodiment, since the seat belt anchor 9 and the reinforcing patches 8a and 8b for the seat leg 12 are integrally formed on the rear portion of the cover panel 8, respectively, the seat belt anchor 9 and the seat leg are formed. Compared with the case where the twelve reinforcing patches 8a and 8b are formed as separate parts, the number of parts can be reduced, and the assemblability can be greatly improved.

It should be noted that 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 integrally form the reinforcing patches for both the seat belt anchor and the seat leg. Needless to say, it is only necessary that at least the reinforcing patch of the seat belt anchor is integrally formed, and various changes can be made without departing from the scope of the present invention.

[0025]

According to the vehicle floor structure of the present invention described above, various excellent effects as described below can be obtained.

(I) According to the invention described in claim 1 of the present invention, when the seat back is folded forward by falling down forward,
Since the seat belt buckle can be pushed down by the seat back and stored in the storage hole of the floor, a pocket on the seat back side as in the conventional case is not required, and the seat back and the seat at the time of seat storage are maintained without impairing the appearance of the seat back. Interference with the belt buckle can be reliably avoided.

(II) According to the first aspect of the present invention, even if an attempt is made to form a recess for storing a seat belt buckle on a floor by sheet metal work, for example, the amount of squeezing is regulated for each location on the floor. It is assumed that it is difficult to obtain a storage recess large enough to completely accommodate the seat belt buckle due to the fact that it is difficult to reduce the shape and make it difficult to attach it. Therefore, a sufficient storage space can be easily secured without special restrictions when forming the storage holes.

(III) According to the second aspect of the present invention, a decrease in strength due to the opening of the storage hole in the floor can be suppressed to a minimum, and sound and water from below the floor can be suppressed. Intrusion of dust and the like into the vehicle interior can be reduced as much as possible.

(IV) According to the third aspect of the present invention, intrusion of sound, water, dust, etc. from under the floor into the vehicle interior can be almost completely prevented. When the object is dropped, it is possible to prevent a problem that the dropped item falls below the floor from the storage hole and cannot be collected.

(V) According to the invention as set forth in claim 4 of the present invention, the number of components can be reduced as compared with the case where the reinforcing patch of the seat belt anchor is formed as a separate component. , Its assemblability can be greatly improved.
