Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to a floorboard structure for a vehicle.

[Technical background and problems]

An example of a conventional vehicle floorboard structure is the one shown in Figure 9 (Nissan Motor Co., Ltd., Service Bulletin No. 471, No. 122, October 1988).
(see page). That is, in the one shown in FIG. 9, the center floorboard 1 is formed as a single plate, and the luggage room 4 is located on the same extended plane as the seat back 3 of the rear seat 2 which is horizontally folded forward.
Floor panel 6 is placed on the floor side box 5 inside.
They are placed at regular intervals. The center floorboard 1 is pivoted at its leading end to a bracket 7 that stands up from the floor panel 6 via a hinge 7a so as to be vertically movable, so that it can be opened and closed. A carpet 8 is laid over the upper surface of the center floorboard 1 and the back surface of the seat back 3 of the rear seat 2. A spare tire 9 is stored in a space formed by a center floorboard 1 and a floor panel 6. In this conventional example, since the center floorboard 1 is located on the same plane as the seatback 3 which is folded forward, the loading length of the luggage can be taken not only on the center floorboard 1 but also on the seatback 3. It is possible to load luggage. In addition, when a load is received from the rear side due to a rear-end collision, etc., the front end of the center floorboard 1 is fixed to the bracket 7 by the hinge 7a, so although the center floorboard 1 is deformed in a curved manner, The safety of the passengers is ensured without them jumping out.

However, in this case, since the center floorboard 1 is a single plate and is fixed via the hinge 7a, the center floorboard 1 cannot be removed, and the space under the center floorboard 1 is used. Not only will it not be possible to load tall items, but if a load is received from the rear side due to a rear collision, etc., the center floorboard 1
There was a drawback that the movement of the hinge 7 was blocked by the hinge 7, which hindered load absorption.

[Purpose of invention]

This idea was devised to solve the problem in view of the actual situation described above, and it is possible to ensure sufficient safety without reducing the safety, but it is also possible to load large items. The purpose of the present invention is to provide a vehicle floorboard structure that can be used in a vehicle.

[Summary of the idea]

This invention consists of floor side boxes that are placed opposite each other with a space in the center on both sides of the luggage room formed on the rear side of the rear seat, and that the luggage room is placed in a suspended manner on the floor side boxes. a center floorboard that divides the floorboard into upper and lower sections, and a carpet laid from the upper part of the back of the seat back to the rear of the upper surface of the center floorboard, and the floor side box supports the center floorboard from below and supports the center floorboard from below. A rail on which the center floorboard is placed so that it can slide back and forth, and a rail formed on the front side of the rail, with the center floorboard interposed between the rail and covering the upper surfaces of the left and right ends of the center floorboard. an insertion part, a stopper on the front side of the insertion part that prevents the center floorboard from moving forward under normal force and can be broken through by an excessive load from the rear in the event of a vehicle collision; The center floorboard includes a front board and a rear board that are divided into two parts in the longitudinal direction of the vehicle. A guide portion is formed to guide the rear board to move below the front board due to the excessive load from the rear due to a vehicle collision, and when the front and rear boards are combined, a single plate is formed. The carpet is fixed to the upper part and both side edges of the back of the seat bag, and is separated from the lower part of the back of the seat bag to form an opening into which the front board can be inserted. It is characterized in that it is supported by the seat bag so as to form a bag-shaped storage section together with the back surface of the seat bag.

〔Example〕

This invention will be explained based on an embodiment shown in FIGS. 1 to 8.

In FIG. 1, a rear seat 22 is provided at the rear of the cabin of a hatchback vehicle, and a seat back 23 of the rear seat 22 is pivotally supported so as to be adjustable in angle in the longitudinal direction. The lower end 23a of the seat bag 23 is formed into an R shape and is designed to be easily slidable. In the luggage room 24 behind the seat back 23, with the seat back 23 horizontally folded forward, a center floorboard 21 extending and located on the same plane is arranged with a vertical distance between it and the roof panel 30. . The floor portion of the luggage room 24 is divided into upper and lower sections by the center floor board 21. The center floorboard 21 is made of a suitable material such as wood, resin, metal, etc., taking into consideration strength and the like.

The center floor board 21 is divided into the front and rear parts of the vehicle, and is composed of a front board 21a and a rear board 21b. It is placed in a suspended manner on floor side boxes 25 that are placed opposite each other on the left and right with a space in the center, so that it can be easily attached and detached. The lower surface of the front end of the front board 21a is formed into an R-shaped sliding portion 31, and when it comes into contact with the R-shaped lower end 23a of the seat bag 23, it can easily slide on the lower end 23a. The front and back sides of the front board 21a and the rear board 21b are respectively formed in an inclined shape with a low front and a high rear, and are joined into a single plate shape without creating a gap.
The guide portion 32 is configured to guide the rear board 21b to move below the front board 21a when a load is applied to the rear board 21b from the rear side of the vehicle.

On the other hand, as shown in FIGS. 2 and 3, the floor side boxes 25 are arranged to face each other on the left and right with a space inside, and the front part is narrow because it is limited by a wheel house panel (not shown). It is widened and widened at the rear. A stepped portion is formed at the inner corner, and this stepped portion constitutes a rail 25a on which the center floorboard 21 is slid and placed. As shown in FIG. 4, the front side of the right rail 25a is formed into a U-shaped insertion portion 33 having a stopper 34 at the tip. This insertion part 33
As shown in FIG. 5, the insertion piece 33a of the front board 21a, which is formed with a step, is loosely fitted and is inserted into the front board 21a so that it can be freely inserted and removed. stoppa 34
is thin enough to prevent the front board 21a from moving forward during normal insertion, but to be pierced by the center floor board 21 when an excessive load is applied from the rear side of the vehicle. Note that the insertion portion 33 is not provided on the left rail 25a.

A trapezoidal guide groove 35 that expands inward is formed at the lower middle of the rail 25a, that is, below the guide portion 32 that is the joint portion between the front board 21a and the rear board 21b. The guide groove 35 is configured to assist the guide portion 32 and guide the rear board 21b below the front board 21a when an excessive load is applied from the rear side due to a rear collision or the like.

As shown in Figure 6, the floor side box 25
The rear part, which is wide and wide, is formed into a box part 36 with an open top for storing small items, and a side floor board 36b is placed on a step part 36a formed around the upper edge of the box part 36. It is closed so that it can be opened and closed freely.

The carpet 28 is attached to the front part 28 of the seat back 23.
a is fixed, and the center floorboard 21 and the floor side boxes 25 are fixed by the loosely fitted rear part 28b.
and covers the entire surface of the side floorboard 36b, that is, the entire luggage room 25. The front edge of the front portion 28a of the carpet 28 is fixed to the upper end of the seat bag 23 by a retainer 37, and the left and right edges are fixed to the left and right edges of the seat bag 23 and the floor side box 25 by suitable fasteners 38 such as fasteners or screws. However, the lower end position of the seat bag 23, that is, the front end side of the front board 21a is open. The front part 28a of the carpet 28 forms a bag-shaped part 39a on the back side of the seat bag 23, with the front edge of the front board 21a as an entrance. It is configured in a storage section 39 in which it is stored when it is received. On the other hand, the rear part 28 of the carpet 28
b is not fixed and has a loose fit, and the center floor board 21 and floor side boxes 2
5 and the side floorboard 36b. The strength of the carpet 28 is set so that it does not pop out even when the front board 21a is stored in the storage section 39.

The spare tire 29 is the center floorboard 21
and the floor panel 26.

Further, 40 is a hook-shaped lock rotatably attached to the lower surface of the rear end of the rear board 21b, and has a handle 40a, and this lock 40 is engaged with an engagement hole 42 provided in the rear end panel 41. The engagement and disengagement can be performed by inserting a hand through an opening 43 formed in the front board 21b, grasping the handle 40a, and rotating the handle 40a.
44 is a back door.

Next, the operation of this invention will be explained.

Center floorboard 21 and roof panel 30
In order to load tall luggage in the luggage room 24, which is larger than the effective loading height of the carpet, the rear part 28b of the carpet 28, which is in the form of a free strip, is first turned over and bundled on the seat back 23 side. Next, the carpet 28 is turned over and the exposed center floorboard 21 is adjusted to match the width, size, etc. of the loaded cargo.
The rear board 21b, the front board 21a, or both are removed as appropriate. At this time, the rear board 21
To remove b, first insert your hand through the opening 43,
When the handle 40a is grasped and rotated upward, the lock 40 is disengaged from the engagement hole 42 of the rear end panel 41. Next, the rear board 21b is slid rearward on the rail 25a and removed at the rear of the vehicle body. To remove the front board 21a, pull the front board 21a backward and pull it out from the insertion portion 33. The front part of the front board 21a has an R-shaped sliding part 31 on the lower surface of the front end, and an insertion part 3.
Since it is only removably inserted into 2 and not fixed, it can be easily carried out while sliding on the rail 25a. And the insertion part 3
The front board 21a extracted from the front board 3 is further pulled rearward, slid on the rail 25a, and removed at the rear of the vehicle body. In this way, when removing the center floorboard 21, the center floorboard 21 is only placed on the rail 25 and is not fixed, and moreover, the center floorboard 21 is separated from the front board 21 and the rear board 2b. This can be done extremely easily by pulling the center floorboard 21 rearward and sliding it on the rails 25a.

When the center floorboard 21 is removed, there is no extra gap between the center floorboard 21 and the spare tire 29, and the effective loading height is the sum of the effective loading height before removal and this gap. Therefore, if the luggage is placed on the floor panel 26 from the rear side of the vehicle, the luggage can be loaded without being obstructed in the height direction. Incidentally, if the spare tire 29 is not stored, it is of course possible to place taller cargo. In addition, in order to place the removed center floorboard 21 on the rail 25a again, insert the center floorboard 2 from the rear side.
1 on the rail 25a, and the front board 21
a is pushed forward until it is stopped by the stopper 34, and then the lock 40 is engaged with the engagement hole 42.

In addition, in order to load long luggage into the vehicle, the seat bag 23 is moved forward horizontally, as in the conventional case.
A seat back 23 and a center floorboard 21 are located on the same plane. Next, by loading luggage onto the center floorboard 21 and seat back 23 from the rear side of the vehicle body, the luggage can be loaded without being obstructed in the longitudinal direction.

Furthermore, the spare tire 29 can be easily loaded and unloaded by removing and attaching the rear board 21b.

If an excessive load is applied from the rear side due to a collision or the like, the vehicle body will collapse from the rear end panel 41 and the back door 44, and the center floorboard 21 will slide on the rail 25a and be pushed forward under the carpet 28, causing the center floorboard 21 to be pushed forward. At the same time, the lock 40 attached to the front board 21b and the engagement hole 42 formed in the rear end panel 41 are disengaged. At this time, as shown in FIG. 7, when the seat back 23 is horizontally tilted forward and the center floor board 21 is located on the same plane as the seat back 23, the rear board 21b is first pushed forward. However, the rear board 21b is blocked by the front board 21a, which is prevented from moving forward by the stopper 34, and is guided by the guide section 32 between the front and rear boards 21a and 21b to move forward. It slides under the front board 21a while absorbing the load, and is further guided by the guide groove 38 and stored in the lower surface side of the front board 21a, that is, in the space between the front board 21a and the floor panel 26 while absorbing the load. Ru. On the other hand, the front board 21
Since a is pressed from behind by the rear board 21b, the stopper 34 of the insertion part 33 provided on the right rail 25a is pierced, and the front board 21b pops out forward while absorbing the load. When the insertion part 33 pops out, the sliding part 31 formed in an R-shape of the front board 21a aligns with the R of the seat back 23.
It comes into contact with the lower end portion 23a formed in a shape. Then, following the contact, the sliding part 31 slides on the lower end part 23a under the carpet 28 while absorbing the load,
Furthermore, it slides from the middle part of the seat bag 23 to the upper end side while absorbing the load, and on the back surface of the seat bag 23, a bag-shaped part 39a is formed as a storage part 39 formed by the front part 28a of the carpet 28. 39 will be slid horizontally and stored while raising it.

Further, as shown in FIG. 8, when the seat back 23 is not folded forward and is in an upright state, the rear board 21b is guided by the guide portion 32 and moves downwardly to the front board 21a while absorbing the load. It moves, is further guided by the guide groove 38, and is stored in the space between the front board 21a and the floor panel 26. On the other hand, the front floorboard 21a also slides into the bag-shaped part 39a, which is the storage part 39 formed by the front part 28a of the carpet 28 in the seat back 23, as described above, but since the seat back 23 is in the upright position, As shown in FIG. 8, the front sliding portion 31 comes into contact with the R-shaped lower end portion 23a of the seat back 23 and immediately contacts the intermediate portion thereof. In this state, the front sliding part 31 is formed in an R shape and is easily slidable, so it slides on the middle part of the seat bag 23 while absorbing the load, raises the carpet 28, and makes the storage part 39 high in the front and low in the rear. stored inside.

In this way, when an excessive load is applied from the rear side of the vehicle, the rear board 21b is guided by the guide portion 32 and moves to the lower side of the front board 21a,
On the other hand, since the front board 21a is moved and stored in the storage section 39, the load is sufficiently absorbed and
The center floorboard 21 does not protrude from below the carpet 28 at all, and there is no danger to the occupants due to the center floorboard 21 protruding.

[Effect of idea]

As is clear from the above, according to this invention, when an excessive load is applied from the rear side, the rear board is guided by the guide section and moves below the front board, while the front board does not move. Since it is stored in the storage section, it can absorb the load and prevent the board from flying out from under the carpet, ensuring sufficient safety while also allowing the floor panel to be easily attached and detached. Therefore, there are effects such as being able to load tall cargo.
