JP-A-10-309991 can be mentioned. Here, cover the spare tire storage room with the main deck board,
A technique is disclosed in which a sliding sub-deck board can be pulled out from a main deck board, and the sub-deck board is also pulled out when the re-ash is moved forward. With such a configuration, a wide rear deck is formed from the rear part of the re-ash, that is, from the back of the seat back to the rear end of the passenger compartment, and a large amount of luggage is loaded by using the rear deck.

[0003]

The above-mentioned prior art has the following problems. Since the deck board is a combination of a main deck board and a sub-deck board in a draw-out manner, a guide mechanism such as a slide rail is required between the two boards, which is disadvantageous in terms of simplification of the structure and weight reduction. At the same time, because of such a polymerized structure,
In order to increase the size of the deck board in the thickness direction as well as to enlarge the vertical space of the luggage room even a little,
After all it is disadvantageous. In addition, since only the spare tire is used as the object storage function, other small items cannot be stored, and further improvement is required in terms of usefulness.

[0004] On the other hand, the rear deck needs a flat luggage loading portion having an area as large as possible.
In order to secure such a loading surface using the back surface of the seat back, it is necessary to dispose each member in accordance with the height of the back surface of the seat back. Furthermore, noise entering the room through the floor panel must be reduced with a structure that is as rational as possible. Front sheet and riyashi-
The sound absorbing material installed on the floor panel near or in the vicinity can maintain high sound absorption at the front of the cabin, but the rear deck at the rear of the liar ash will have sufficient sound insulation unless special sound absorbing measures are taken. It is not a measure.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems and requirements described above. According to the first aspect of the present invention, there is provided a vehicle in which a releasable slidable in the front-rear direction is provided, and a deck board is disposed at the rear thereof, wherein a hinge having a rotation axis in a vehicle width direction is provided at a front end of the deck board. When the auxiliary board was attached, the auxiliary board was put on the deck board when not used, and when the auxiliary board was used, the auxiliary board was rotated forward around the hinge and the front portion of the board was tilted forward. It is characterized in that it is configured to be placed on the back of the seat back.

Accordingly, the rear surface of the seat back slid forward is flat and continuous to the rear end of the deck board, so that a large load area can be secured. Further, since the auxiliary board is attached by the hinge, the structure required for installing the auxiliary board may be only the hinge, which is suitable for simplifying the structure. The auxiliary board can be stored on the deck board body when not in use by being superimposed on the deck board body, so that the size of the deck board in the thickness direction can be minimized.

According to a second aspect of the present invention, in the first aspect, the storage portion of the auxiliary board is formed one step lower than the general surface of the deck board, and when the auxiliary board is not used, the back surface of the auxiliary board and the general surface are flush with each other. Is characterized in that it is located at By doing so, when the auxiliary board is not used, the entire deck board has a flat deck surface with no steps, and the stability of the load is improved. Also, because it looks flat and neat,
This is effective for improving the appearance quality.

A third aspect of the present invention is characterized in that, in the first or second aspect, the deck board functions as a lid of a storage box. Since the size of the lid in the thickness direction is minimized as described above, it is effective to increase the vertical depth of the storage box even if it is small. The greater the lid thickness, the more the effective depth of the storage box is sacrificed.

According to a fourth aspect of the present invention, in the third aspect, the storage box is placed on a spare tire. Generally, the recess for the spare tire formed in the rear floor panel is deepened to such a level that the minimum ground clearance is not hindered, and the indoor space in the vertical direction is enlarged as much as possible. Since the storage box is arranged in the enlarged space, the storage container can be successfully arranged on the rear deck. In particular, the seat back of the fallen re-yacht is located quite high from the floor panel, so that the deck board also needs to be adjusted to the height. In such a situation, since the storage box is placed on the spare tire, the deck board can be arranged at a high position. Further, since the storage box is mounted on the spare tire, the shock to the storage box can be reduced by the buffering action of the spare tire, which is convenient for the stored articles.

According to a fifth aspect of the present invention, there is provided a storage box in which a rear slidable rear slat is provided and a rear deck is formed as a rear deck. Are arranged. The noise during running, such as the differential device, the suspension device or the rolling noise of the tire, enters the room from the rear deck as a transmitted sound,
Since a storage box made of a material having good sound absorbing properties is installed, transmitted sound is absorbed here, which is effective for keeping the room quiet. Furthermore, when the storage box is covered with the deck board, the enclosed space in the storage box becomes a sound absorbing space, so that a further sound insulation effect can be obtained.

A sixth aspect of the present invention is characterized in that, in the fifth aspect, the storage box is placed on a spare tire. Therefore, in addition to the effect of the fifth aspect, the buffer effect of the spare tire is added to the storage box, so that a more excellent sound insulation effect can be obtained.

[0025]

According to the present invention, in a type in which a re-seat which is slidable in the front-rear direction is provided and a deck board is disposed behind the re-seat, a pivot shaft in the vehicle width direction is provided at the front end of the deck board. When the auxiliary board is not used, the auxiliary board is attached to the deck board, and when the auxiliary board is not used, the auxiliary board is turned around the hinge when the auxiliary board is used, and the front portion of the board is moved forward. It is characterized in that it is configured to be placed on the back of a seat back that has been folded down.

Therefore, the rear surface of the seat back slid forward becomes flat and continuous up to the rear end of the deck board, so that a large load area can be secured. In addition, since the auxiliary board is attached by the hinge, the structure required for installing the auxiliary board is only the hinge, and the simplification of the structure can be achieved by avoiding the use of the rail mechanism as in the prior art. Since the auxiliary board can be stored when not in use by being superimposed on the deck board body, the size of the deck board in the thickness direction can be minimized. This is effective for reducing the dimension in the thickness direction as much as possible to expand the vehicle interior space.

The storage portion of the auxiliary board is formed one step lower than the general surface of the deck board. When the auxiliary board is not used, the rear surface of the auxiliary board and the general surface are arranged on the same plane. When used, the entire deck board has a flat deck surface with no steps, improving the stability of the load. In addition, since the appearance is flat and clear, it is effective for improving the appearance quality.

[0028] The deck board is characterized in that it functions as a lid of a storage box. Since the size of the lid in the thickness direction is minimized as described above, it is effective to increase the vertical depth of the storage box even if it is small. The greater the lid thickness, the more the effective depth of the storage box is sacrificed.

The storage box is characterized in that it is mounted on a spare tire. Generally, the recess for the spare tire formed in the rear floor panel is deepened to such a level that the minimum ground clearance is not hindered, and the indoor space in the vertical direction is enlarged as much as possible. Since the storage box is arranged in the enlarged space, the storage container can be successfully arranged on the rear deck. Above all,
Since the seat back of the fallen re-yacht is located quite high from the floor panel, the deck board also needs to be adjusted to the height. In such a situation, since the storage box is placed on the spare tire, the deck board can be arranged at a high position. Furthermore, since the storage box is mounted on the spare tire, the shock of the storage box can be reduced by the buffering action of the spare tire, which is convenient for the stored articles.

The above points are favorable for the layout design of the floor panel. That is, if the rear floor panel is set at a position as low as possible, it becomes difficult to match the height of the deck board disposed above the rear panel with the rear surface of the seat back of the ream. Such a height problem is solved by the intervention of a storage box. Therefore, the degree of freedom in designing the rear floor panel can be increased.

A rear slidable rear slat is provided, and the rear deck is provided with a rear deck. In the rear deck, a storage box made of a material having good sound absorbing properties is provided. The noise during running, such as differential gears, suspension equipment, or rolling noise of tires, enters the room from the rear deck as transmitted sound, but a storage box made of a material with good sound absorption is installed. The transmitted sound is absorbed here, which is effective in keeping the room quiet. Furthermore, when the storage box is covered with the deck board, the enclosed space in the storage box becomes a sound absorbing space, so that a further sound insulation effect can be obtained. By providing sound insulation measures for the rear deck in this manner, excellent comfort can be obtained in combination with sound insulation measures for the front sheet and re-leased parts.

The storage box is made of a sound-absorbing material, which is mounted on a spare tire. Therefore, in addition to the above-described sound absorbing effect, the buffer effect of the spare tire is added to the storage box, so that a more excellent sound insulating effect can be obtained.
