Abstract

PURPOSE:To stabilize the locus of the rear seat when stored, and facilitate the storing operation by energizing the seat cushion in the forward-inclined direction, and at the same time, providing a stopper means to keep the angle between the seat cushion and the leg to the specified value. CONSTITUTION:At first, a seat back 8 is collapsed forward to be folded onto a seat cushion 2, and the engagement of a latch mechanism 5 with a striker 4 is released by an operation lever 6. Then a leg 3 is collapsed forward, and the seat cushion 2 is stored in a recessed part 7 in the forward-inclined position. Then, the energizing force of a spring 13 pushes down the rear part of the seat cushion 2 to the position of inversion. This allows the seat back 8 to be stored. In this storing operation, the seat back 8 is pushingly pressed onto the bottom surface of the recessed part 7 by means of the spring 13, and wobbling during traveling is prevented, decreasing the danger of the hand and foot of the passenger being caught.

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 mounted on a luggage-carrying vehicle such as a van or a one-box car.

[0002]

2. Description of the Related Art The applicant previously proposed a rear seat that can be easily stored (see Japanese Utility Model Application No. 2-120970). As shown in FIG. 5, this rear seat has legs 3 pivotally connected to the floor panel 1 and the seat cushion 2 at both ends.
Is equipped with. Further, the seat operation 2 is provided with a striker 4 on the back surface, and the striker 4 is engaged with the latch mechanism 5 to set the rear seat. Then, when the engagement of the latch mechanism 5 is released by the operation lever 6 and the leg 3 is tilted forward, the rear seat is stored in the recess 7 of the floor panel 1 as shown by the chain double-dashed line.

[0003]

However, since both ends of the leg 3 are pivotally connected to each other in the rear seat, the locus during storage is not stable, and when the front seat is slid backward, The headrest 9 of the back 8 hits the front seat, making it difficult to store.

Further, since it is designed to be lifted from the bottom of the recess 8 for setting, the setting is not easy.

In view of the above circumstances, the present invention has an object of providing a retractable rear seat having excellent operability.

[0006]

According to the present invention for solving the above-mentioned problems, a rear seat accommodating recess is provided in a floor panel, and a rear portion of a seat cushion is placed and held at an opening rear edge of the recess, and both ends of the recess are accommodated. In a retractable rear seat having legs that are rotatably connected in the front-rear direction to the back surface of the seat cushion and the bottom surface of the recess, respectively, a spring is installed between the seat cushion and the legs to tilt the seat cushion forward. It is characterized in that a stopper means for urging the seat cushion and the leg at a predetermined value is provided.

[0007]

1 shows a retractable rear seat of the present invention. In this rear seat, one end of the leg 3 is pivotally connected to the frame 2a of the seat cushion 2 by a first pin 10. A second pin 11 is planted in front of the first pin 10 on the frame 2a. In addition, as shown in FIG. 3, a third pin 12 having a large diameter portion 12a is provided in the vicinity of the first pin 10 of the leg 3 so as to penetrate between the pin 12 and the second pin 11. A spring 13 is installed between them. Further, one end of an arm 14 is rotatably attached to the opposite side of the third pin 12. This arm 1
4 has a long hole 14a at the end opposite to the pin 11, and a fourth pin 15 planted in the frame 2a is engaged with the long hole 14a (see FIGS. 4 and 5). .. As a result, the seat cushion 2 is biased in the forward tilting direction (direction of arrow C in the figure) by the spring 13, but the frame 2a and the leg 3 of the seat cushion 2 are connected to each other by the arm 14 (stopper means). , Frame 2a
The angle between the leg 3 and the leg 3 does not become smaller than that at the time of setting shown in FIG. That is, at this time, the fourth pin 15 engages with one end of the elongated hole 14a of the arm 14 to prevent the seat cushion 2 from rotating, as shown in FIG. On the other hand, at the time of storage, the first pin 10 is located below the line connecting the second and third pins 11 and 12, and the spring 13 biases the seat cushion 2 in the direction of arrow D in the drawing. It is designed to be pressed against the panel 1. It should be noted that when the rear portion of the seat cushion 2 is slightly lifted from here, the three pins 10, 11, 12 are aligned, and the biasing direction of the spring 13 is reversed. The other members have the same structure as the conventional example shown in FIG.

Since the rear seat is constructed in this way, it can be stored as follows. First, the seat back 8 is tilted forward and folded over the seat cushion 2, and the operation lever 6 is used to strike the striker 4 of the latch mechanism 5.
To disengage. Next, the leg 3 is tilted forward, the seat cushion 2 is put in the recess 7 in a forward tilted posture as shown by the chain double-dashed line in FIG. 1, and then the rear portion of the seat cushion 2 is moved to a position where the biasing force of the spring 13 is reversed. Just push it down.

On the other hand, when setting, when the rear portion of the seat cushion 2 is lightly lifted, the rear seat jumps up as shown by the chain double-dashed line, so that the leg 3 is raised and the striker 4 is engaged with the latch mechanism 5. Good.

This rear seat has a spring 1 when stored.
Since it is pressed against the bottom surface of the concave portion 7 by 3, the rattling at the time of traveling can be prevented, and the risk of the occupant's limbs being pinched is reduced. If the seat cushion 2 is fixed to the bottom surface of the recess 7 at the time of storage, it is not necessary to arrange the first to third pins 10, 11, 12 as described above.

[0011]

In the rear seat of the present invention, the angle between the seat cushion and the leg is maintained at a predetermined value by the spring and the stopper means, so the locus at the time of storage can be stabilized, and Easy to operate.

Further, since the seat cushion is biased in the forward tilting direction by the spring, the seat cushion can be jumped up from the recessed portion by simply lifting the rear portion thereof at the time of storage, and the setting operation becomes easy.
