Description of the Related Art Generally, in an automobile called a wagon type, an engine 2 is mounted horizontally on a front portion of a vehicle body 1 to drive front wheels 3, 3 as shown in FIGS. In the body 1 of the FF vehicle, the first row of seats 6 including the driver's seat 4 and the passenger's seat 5 and the second and third rows of seats 7 and 8 each including a bench seat are provided on the floor. 9 is provided on the front and rear.

[0003] In an automobile having such a seat arrangement, the occupants of the second and third rows of seats 7 and 8 pass through doors provided on the side of the vehicle body beside the second row of seats 7. Getting on and off is performed.

In the above-described seat arrangement, even if the third row of seats 8 generally has a width that can be seated by three occupants, the getting on / off passage 10 for the third row of seats 8 can be used.
The second row of seats 7 is formed to be narrower than the third row of seats 8 in a form in which the door-side portion thereof is cut off to form a two-seat seat. Usually, the number of passengers is usually seven.

As shown in FIG. 7, the lower portion of the front end of the seat cushion 8a of the third row of seats 8 is
When the rear of the second row of seats 7 is used as a luggage compartment, the seat back 8b of the third row of seats 8 is tilted forward to place the seat back 8b on the seat cushion 8a. Then, the seat cushion 8a is raised forward with the seat back 8b around the pivot shaft 11 to lean against the rear of the seat 7 in the second row (double action field). .

In Japanese Utility Model Laid-Open Publication No. 3-47825, for example, a seat cushion is provided on a floor via a parallel link mechanism, and when a seat is folded, a seat back is turned forward on the seat cushion, and then a parallel link mechanism is provided. Discloses a foldable seat configured to expand the luggage compartment by translating the entire seat downward.

[0007]

By the way, in the conventional double action folding type folding seat structure as shown in FIG. 7, the rear of the second row of seats 7 is used as a luggage compartment. When the sheets 8 in the third row are folded, the folded sheets 8 in the third row remain in the luggage compartment area, so that there is a problem that the effect of enlarging the luggage compartment portion is reduced accordingly.

If the seats 6 and 7 in the first and second rows have two seatable persons, respectively, the third row of seats 8 having three seatable persons is folded and The number of personnel must be limited to four, and an increase in the number of passengers in this case has been demanded.

In view of the above circumstances, the present invention relates to a vehicle in which a plurality of rows of seats are arranged on the floor in front and rear,
It is an object of the present invention to provide a vehicle seat structure capable of further expanding a luggage room area when a part of a seat is folded to enlarge a luggage room, and capable of minimizing a decrease in occupant capacity.

[0010]

A vehicle seat structure according to the present invention comprises a seat cushion and a seat back on a floor.
Front row seat having a seat cushion, a seat cushion and a seat
It has a back and can be boarded from the front row seat
A vehicle with a large number of rear row seats arranged in front and back
The seat back of the front row seat can be tilted forward
As well as the seat
When placed on the floor, it is almost parallel to the floor
The back row sheet is a sheet of the front row sheet.
Seat back of the front row seats on the cushion
It is configured to be movable on the surface opposite to the backrest surface of the
And can be seated when moved on the surface

It is characterized by the following.

[0011]

According to the present invention, when a part of a seat is folded to expand the luggage compartment, the front row seat is folded and the rear row seat is moved above the folded front row seat. Since the seat can be held at the moving position, the capacity of the luggage compartment can be increased as compared with the conventional case where the back row seat is folded.

When the number of seats capable of seating in the rear row seats is larger than the number of seatable staffs of the front row seats, a decrease in the number of seats that can be loaded when the luggage compartment is expanded is minimized while always securing a passage for getting in and out of the rear seats. Can be minimized.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing one embodiment of a vehicle seat structure according to the present invention, and FIG. 2 is a plan view thereof.

The seat arrangement of this embodiment is the same as that of FIGS. 5 and 6 described above, and corresponding parts are denoted by the same reference numerals.

As shown in FIGS. 1 and 2, the seat cushion 7a of the second row of seats 7 composed of two bench seats has relatively short and straight links at the front and rear positions on both sides thereof. The link members 12a, 12b are supported on the floor 9 by the members 12a, 12b.
The lower end of b is connected to the floor 9 via pivot shafts A and B, respectively, and the upper end is connected to the side surface of the seat cushion 7a via pivot shafts C and D, respectively, to form a parallel link mechanism. .

Further, between the intermediate position of the front link member 12a and the floor 9 behind the pivot shaft A, a stay 13 which can be folded in two in a jackknife manner is obliquely connected, and the stay 13 is extended. When locked, the link member 12
a is locked in the upright posture shown in FIG. 1, whereby the seats 7 in the second row are configured to maintain the seatable state shown in FIG.

The seat back 7b of the second row of seats 7 is pivoted about the pivot axis L as a seat cushion 7b.
a, when the seat 7 is pushed backward, and after the stay 13 is unlocked to make it bendable in two, the seat 7 is pushed backward.
The link members 12a and 12b are respectively moved substantially 90 ° rearward around the pivot shafts A and B until they become parallel to the floor 9 surface.
By pivoting, the second row of seats 7 translates rearward and downward to bring the lower surface of the seat cushion 7a into close contact with the floor 9 as shown in FIG. It is in a folded state with the back side facing upwards horizontally.

On the other hand, on both sides of the seat cushion 8a of the third row of seats 8 consisting of three bench seats,
The link members 14a and 14b are connected to the floor 9 via pivot shafts E and F, respectively. , Upper ends are pivot shafts G and H respectively
And is connected to the side surface of the seat cushion 8a via a parallel link mechanism.

The floor 15 at the portion where the third row of seats 8 is provided is one step higher than the floor 9 in front of it, and the seat cushion 8a of the third row of seats 8 is As shown in FIG. 4, the rear link member 14b supported on the floor 15 is locked by a releasable automatic lock mechanism 16 erected on the floor 9 as shown in FIG. The seat 8 is locked in the rear position shown in FIGS.

After the second row of seats 7 is folded into the state shown in FIG. 3, the lock of the link member 14b by the lock mechanism 16 is released, and the third row of seats 8 is pulled upward and forward. And the link members 14a and 14b pivot forward about the pivot shafts E and F, respectively, so that the third row of seats 8 translates forward and the folded second row of seats 8 moves. The seat 7 is placed on the seat back 7b. At the same time, the rear link member 14b is engaged and locked with the releasable automatic lock mechanism 17 erected on the floor 9, whereby the third row of seats 8 is moved to the second row. The seat can be held at a position above the eye sheet 7.

Further, in this case, the seat cushion 8a of the seat 8 in the third row is supported on the floor 15 at the rear position shown in FIGS. 1 and 4, and is folded at the front position shown in FIG. Since the link members 14a and 14b are placed on the second row of sheets 7 so that no load is applied to the link members 14a and 14b, the link members 14a and 14b are lightweight.
