CONSTITUTION:A stay provided at the lower end of a seat back is connected in the pivotally supported state to a bracket 5L installed at a floor panel 4 and to a bracket on the side face of a seat cushion respectively by pins. The front part of the seat cushion is provided with a leg, and the leg is connected in the pivotally supported state to the seat cushion and the bracket respectively by pins so as to allow a rear seat to be stored in the overlapped state of the seat back and seat cushion. The locking part 16 of a tongue piece 15 at the front end of the lower end folded part 14 of the bracket 5L is engaged with a T-stud planted in a floor 4. The seat can be thereby held in an erected position, and fitting is facilitated to improve work performance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable rear seat mounting structure, and more particularly to a bracket mounting structure for pivotally connecting a seat back stay to a floor.

[0002]

2. Description of the Related Art The applicant has previously proposed a retractable rear seat having a four-bar rotary link mechanism and excellent in operability (see Japanese Patent Application No. 5-212675). In this seat, since the bracket supporting the stay of the seat back is arranged below the seat cushion, the bracket must be attached to the floor before the legs of the seat cushion. Therefore, the seat back is held at the upright position by the lock mechanism, the seat cushion is folded over the seat back and restrained by a belt or the like, and then the bracket is fixed to the floor with bolts. However, the fastening of the bolts must be performed while supporting the seat from trying to fall backward, and the workability is extremely poor. In view of such circumstances, an object of the present invention is to provide a mounting structure for a retractable rear seat in which a folded back seat and a seat cushion can be temporarily fixed in an upright state.

[0003]

DISCLOSURE OF THE INVENTION The present invention for solving the above-mentioned problems includes a stay extending downward from a lower end of a seat back, a bracket fixed to a floor for pivotally connecting the stay, and the seat back. In the retractable rear seat provided with a seat cushion pivotally connected to each other, a leg whose both ends are respectively pivotally connected to the seat cushion and the floor, and a lock mechanism for restricting rotation of the stay with respect to the bracket, It is characterized in that the T stud is scrambled and that the engaging portion engageable with the T stud is formed at the front end of the bracket.

[0004]

FIG. 7 shows a retractable rear seat according to the present invention. The seat 1 is provided with a stay 3 at a lower end of a seat back 2, and the stay 3 is pivotally connected to a bracket 5 installed on a floor panel 4 by a pin 6. On the other hand, the seat cushion 7 is provided with a bracket 8 on its side surface, and the bracket 8 is pivotally connected to the seat back 2 by a pin 9.
Further, the seat cushion 7 is provided with a leg 10 at the front part, and both ends of the leg 10 are pivotally connected to the seat cushion 7 and the bracket 13 by pins 11 and 12. That is, this rear seat 1 is installed on the floor panel 4 by a four-bar rotary link mechanism. By the way, the seat back 2 is held in an upright position by restricting its rotation with respect to the pin 6 by a lock mechanism (not shown).
Now, when the lock mechanism is released and the seat back 2 is tilted forward, the leg 10 also tilts forward, and the seat back 2 is folded and stored on the seat cushion 7 (see FIG. 8). The seat back 2 is constrained by the lock mechanism even at this position.

The seat back 2 is actually provided with stays 3 on the left and right as shown in FIG. 3, and the lock mechanism is installed on the left bracket 5L to restrict the rotation of the left stay 3L. I am doing it. The right stay 3R is simply pivotally connected to the bracket 5R. The left bracket 5L is provided with a bent portion 14 at the lower end, and a pair of tongue pieces 15 are extended at the front end of the bent portion 14 to form a locking portion 16.
Has been formed. On the other hand, the right bracket 5R is provided with a cut-and-raised piece 17 directed downward. The leg 10 is formed in a U shape, and brackets 13 are installed on both ends of the leg 10. Of these, the left bracket 13
A cut-and-raised piece 18 is provided in L downward.

The rear seat 1 is attached to the floor as follows. First, the seat back 2 is held at the standing position by the lock mechanism, and the seat cushion 7 is raised as shown in FIG. 1 to be folded over the seat back 2 and restrained by a belt or the like. Then, the engaging portion 16 of the left bracket 5L is engaged with the T stud 19 planted in the floor panel 4, and the cut-and-raised piece 17 of the right bracket 5R is engaged with the hole 20 of the floor panel. As a result, the left and right brackets 5L and 5R are also positioned while the seat 1 is held in the upright state. In this state, bolts (not shown) are passed through the holes 21 of the bracket 5 and the holes 22 of the floor panel 4,
The bracket 5 is fixed to the floor panel 4. Thereafter, as shown in FIG. 2, the seat back 7 is rotated forward to engage the cut-and-raised piece 18 of the left bracket 13L with the hole 23 of the floor panel, and then the left and right brackets 13 are similarly fixed with bolts. .

In this embodiment, the left side bracket 5L is made higher than the right side bracket 5 so as to correspond to the step portion 4a of the floor panel 4, but the present invention is limited to such a structure. is not. Also, of the floor panel 4,
The mounting surface of the bracket 5 on the rear side need not be inclined downward.

[0008]

According to the present invention, the seat can be held in the upright state only by engaging the engaging portion of the bracket with the T-stud planted on the floor, so that the bracket can be easily attached and the workability is improved. Can be greatly improved.
