DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat back carpet mounting structure. More specifically, a pair of left and right seat backs are provided so as to be independently tiltable back and forth, and a carpet is provided on the rear side of the seat back. To a carpet mounting structure of a seat back to which each is mounted.

[0002]

2. Description of the Related Art Generally, a pair of left and right seatbacks of a rear seat of a vehicle seat are provided so as to be independently tiltable back and forth, and the luggage is placed on the rear side of the seatback by tilting the seatback forward. The seating space and the luggage space in the vehicle cabin can be changed as appropriate.

[0003] A carpet is mounted on the rear side of the seat back because luggage and the like are placed when the seat back is moved forward. As shown in FIG. 6, the terminals 3a on the sides of the carpet 3 are attached to the board 5, and are respectively wrapped around the back side of the board 5 so as to protrude outward from the side ends 1a of the seat back 1. Flexible part 3 which is fixed and does not have board 5 on carpet 3
b is formed, and the length L1 of the flexible portion 3b where the board 5 does not exist is formed large. The configuration of the pair of left and right seatbacks 1 and 1 is also substantially the same.

If there is a large gap between the mutually adjacent side ends 1a, 1a of the pair of left and right seatbacks 1, 1 to which the carpets 3, 3 are respectively attached, objects may fall from the gap. In addition, there is a risk that dust or the like may fall and contaminate the seat cushion. If there is no gap, mutual frictional resistance increases, and it becomes difficult to independently tilt the seat backs 1, 1 back and forth. Had disadvantages. For this purpose, flexible portions 3b, 3b without the boards 5, 5 are formed on the carpets 3, 3, and the flexible portions 3b, 3b are overlapped with each other, so that the pair of left and right seat backs 1, 1 is independently formed. Side ends 1 that can be tilted back and forth and are adjacent to each other
There is a seat back carpet mounting structure that does not expose the gap between the a and la and improves the appearance.

[0005]

However, in the conventional carpet mounting structure for a seat back, the carpets 3, 3 projecting outward from the rear side end portions 1a, 1a of the seat backs 1, 1 are provided. Flexible part 3b,
When the flexible portions 3b, 3b are formed large, there is a drawback that the amount of use of the carpet 3 increases, and further, the carpet 3 is folded to a portion where the board 5 does not exist. The work is complicated,
There is a possibility that a dimensional error may occur, and there is a disadvantage that the assembly cannot be performed easily and quickly. In addition, since the flexible portions 3b overlap each other, the flexible portions 3b, 3b are greatly deformed, deteriorating the appearance of the back side of the seat back 1 and failing to improve the appearance. Was.

SUMMARY OF THE INVENTION It is an object of the present invention to ensure that the carpet can be folded back at the side edge of the board, the assembling operation can be performed easily and quickly, the amount of carpet used can be reduced, and a flexible portion can be used. It is an object of the present invention to provide a seat back carpet mounting structure which is capable of preventing deformation of the seat back and improving the appearance of the rear side of the seat back and which is excellent in economic efficiency.
