By the way, there is a demand for a rear seat that can adjust the seat position in the vehicle length direction for reasons such as the physique of passengers and the ease of getting on and off. However, the above-mentioned conventional technique is intended for a rear seat that does not have a sliding structure, and it is difficult to apply it to a seat that can move forward and backward in the vehicle length direction.

The present invention has been made in response to this type of request, and accommodates a seat having a seating portion and a backrest portion, which is capable of advancing and retreating in the vehicle length direction, easily and reliably with a simple structure. An object of the present invention is to provide a vehicle seat storage structure that can be used.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a seat is configured to be capable of advancing and retracting in the vehicle length direction under the guiding action of a fixed side rail member and a movable side rail member. In the state where the backrest is folded, the fixing of the seat portion by the locking means is released, and the seat portion is further swung about the swing fulcrum. Therefore, the seat that can move forward and backward in the vehicle length direction can be easily and surely stored with a simple structure, and the convenience and the functionality of the luggage carrier can be effectively improved.

At this time, since the swing fulcrum is arranged between the movable side rail member and the engaging portion of the movable side rail member, the swing fulcrum is firmly held without being shaken left and right. As a result, the seat can be swung smoothly and accurately in a wide swing range, and the size can be easily reduced.

Further, since the seat storage portion is provided on the swing fulcrum side at a position lower than the floor on which the fixed side rail member is disposed, the folded seat is stored in the seat storage portion. It becomes possible to secure a relatively large space above the seat.

Further, when the seat is stored in the seat storage portion provided at the rear, the bottom surface of the seating portion and the floor are flush with each other. As a result, the cargo space from the floor to the bottom of the seat is effectively expanded, and the workability of handling luggage and the like is improved all at once.

Furthermore, if the fixed side rail member and the movable side rail member are integrally covered with the side lining member, when the folded seat is swung, the fixed side rail member and the movable side rail member are indoors. Never exposed to.

Moreover, since the side panel is provided with the concave portion for disposing the fixed side rail member and the movable side rail member, the side liner member has no convex portion.
Therefore, the sheet width can be set large.
