Description

[Detailed description of the invention] The present invention relates to a rear seat for a vehicle, for example a van-type vehicle such as a passenger/freight vehicle, and more specifically, two rows of seats, front and rear, are arranged on the floor at the rear of the vehicle. This invention relates to a storage structure for a double-row folding seat.

Two types of double-row seats that are usually installed in the rear compartment of a van-type vehicle include those in which the front row is fixed and the rear row is foldable, and those in which both the front and rear rows are foldable. Although double-row folding seats that can be folded both front and rear are advantageous in that they can provide a large cargo space, the reality is that the folding position, or storage form, is not always effective. It is. Figure 13 shows a conventional example of a double-row folding seat, in which a second seat 3 that has been folded horizontally is stacked above the first seat 2 that has been folded upside down. However, as you can see from the diagram, both seats 2 and 3 could not be stored compactly, and it was almost impossible to get between the driver's seat and the rear compartment. .

The purpose of the present invention is to solve the above-mentioned drawbacks of the conventional technology.
To provide a storage structure for a double-row folding seat for a vehicle, in which the seat can be stored compactly and a space for a luggage compartment can be effectively obtained.

In order to achieve the above object, the present invention includes a first seat in which the backrest and rear legs are foldable to the lower surface of the cushion, and the backrest is foldable to the upper surface of the cushion. and a second seat whose rear legs are foldably attached to the lower surface of the cushion portion, and which are disposed in the front-rear direction on the floor surface at the rear of the vehicle. The lower ends of the front legs of the seat are attached so as to be able to rise and fall on the floor surface, and a storage arm is provided below the first seat that extends in the front-rear direction of the floor surface and whose front end is attached so that it can rise and fall on the floor surface. In addition, the rear end of the storage arm and the front part of the cushion portion of the second seat are connected by a front leg made of an inversion link, so that the second seat can be folded and stored at a position below the first seat. In addition, the first seat and the second seat can be folded forward and stored upside down.

A locking mechanism 21 (details not shown) is provided for holding the cushion portion 18 in a position substantially perpendicular to the cushion portion 18. The front legs 22 of the second seat 3 are constructed with reversible links formed in a U-shape in plan view. That is, the front legs 22 are arranged on the floor surface 1 between the rear end of the first seat 2 and the front end of the second seat 3, and both rear end portions, which are open sides, are bent upward. The upper end is rotatably connected to the frame 18a at the front end of the cushion section 18 in the second seat 3 by a pin 23. Further, both sides of the front end of the front legs 22 are fixed with bolts 25a to the left and right rear ends of a storage arm 24, which is arranged to extend on the floor surface 1 below the first seat 2 and is formed into a U-shape in plane. It is rotatably supported by a pair of upper and lower arm brackets 25. The storage arm 24 has brackets 26 on both sides of its front end, and the brackets 26 are rotatably supported by a pin 9a of a hinge 9 for supporting the front legs 8 of the first seat 2. Also,
The front end of the front leg 22 for the second seat 3 lies on the floor surface 1 in parallel with the lower end of the rear leg 10 for the first seat 2, and partially overlaps the locking plate 17. A stop plate 27 with a hole is provided in a protruding manner, and when the rear leg 10 is fixed by the lock plate 15, the rear leg 10 is locked to the lock plate 17 together with the rear leg 10.

In addition, the front legs 22 for the second seat 3 include
A hook 28 is provided for fixing the to the floor 1. The hook 28 has a pin 2 on the bottom of the vertical part of the front leg.
9, and has a claw 31 at its lower end that can be engaged with and detached from a locking plate 30 with square holes fixed to the corrugated floor surface 1.
The hook 28 is constantly applied with rotational force in the locking direction by the tension spring 32, and the front leg 28 is moved so as to engage with the arc-shaped elongated hole 33 formed at the upper end.
The rotation range is regulated by a stopper pin 34 protruding from 2. The lock release lever 35, which is arranged parallel to the vertical part of the front leg 22, has an upper end attached to the frame 18a of the cushion part 18 with a pin 3.

and a rubber cushion 45, and a tension spring 46 applies rotational force in two directions: front and rear.

The double-row folding seat of this embodiment constructed as described above is set in the rear compartment of a vehicle as shown in Fig. 9, and the method of folding it will be explained below based on Figs. 10 to 12. explain.

When folding the second seat 3 in the back row, first fold the backrest 19 of the second seat 3 over the upper surface of the cushion part 18, then operate the lock handle 16 to fold the rear legs 10 and the second seat in the first seat 2. After operating the lock handle 44 of the rear leg 40 of the seat 3 to release the lock by the lock plates 15, 43, the entire first seat 2 is moved from the front leg 8 to the floor surface 1 as shown by the imaginary line in FIG. Lean forward around the fulcrum. Next, when the rear end of the cushion part 18 of the second seat 3 is lifted, the cushion part 18
rotates around the pin 23 which is the connection point with the front leg 22, and accordingly the lock release lever 35 is pulled up as shown by the imaginary line in FIG. 6, causing the hook 28 to rotate against the tension spring 32. It is released from the locking plate 30. At this time, the edge of the elongated hole 33 of the hook 28 comes into contact with the stopper pin 34, and the movement of the hook 28 and the lock release lever 35 is restricted, so in this state, the second seat 3 is further lifted and moved forward. When moving, the front leg 22 is flipped forward using the front end supported by the storage arm 24 as a fulcrum. After that, when the first seat 2 which was tilted forward is returned to its original position, the second seat 3 is moved as shown in Fig. 7 and 1.
As shown in Figure 0, it is folded horizontally and stored directly below the first seat 2, so in this case, the area behind the first seat 2 can be effectively used as a cargo space.

Furthermore, when folding both the first and second seats 2 and 3, with the second seat 3 folded as described above, first fold the backrest 5 of the first seat 2 horizontally backwards, and then fold the entire seat back. As shown by the solid line in FIG. 11, the lower end of the front leg 8 is used as a fulcrum and the lower end of the front leg 8 is used as a fulcrum to rotate it forward to stand upside down, and then fold the back leg 10 over the lower surface of the cushion part 4 and lower the backrest part 19 of the second seat 3. Once rotated in the upright direction, the backrest 5 of the first seat 2 is folded over the lower surface of the cushion 4, and then the backrest 19 of the second seat 3 is folded over the cushion 18 again. , when the rear part of the second seat 3 is lifted, the second seat 3 is moved together with the storage arm 24.
The first seat 2 is rotated forward using the front end of 4 as a fulcrum.
(See FIGS. 8 and 12). In other words, the first seat 2 and the second seat
The seats 3 are stacked against the front side of the rear compartment and stored upside down in a horizontally stacked manner. By folding in this manner, a compact storage position with no dead space is achieved, thus providing effective cargo space and allowing access between the driver's seat and the rear compartment.

Note that assembly of the seat is achieved by performing the folding operation in the reverse order as described above.

As described above, the present invention enables the second seat in the back row of a double-row folding seat to be stored below the first seat in the front row, and also allows both seats to be folded together and stored upside down, which is an improvement over the conventional method. It is a useful idea as a storage structure for double-row folding seats, as it can more effectively secure cargo space when stored than the previous model, and also allows access between the driver's seat and the rear compartment.
