DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rear seat structure for a vehicle, and more particularly to a rear seat structure for a vehicle, in which the rear seat is comprised of a plurality of seats divided into left and right sections.

(Prior Art) Generally, the rear seats of commercial vehicles, which have a luggage compartment formed at the rear, are bench-shaped and have a seat cushion provided with a seat back.

Such a bench type seat is, for example,
There is a vehicle seat device shown in Japanese Patent No. 0933, which consists of two seats divided into left and right halves, and each seat is individually movable back and forth on the floor. If the seat can be moved back and forth in this way, it is effective to expand the seat space and improve the comfort of the occupants.

However, commercial vehicles that have a cargo space behind the rear seats are intended to always have a certain amount of cargo space, so in order to expand the seat space, the rear seat must be slid into the rear cargo space. It was inconvenient to narrow the space. Therefore, in order to always ensure a constant cargo space, only one of the left and right seats is supported so that it can be moved backwards, and the seat back of the other seat is moved forward toward the seat cushion. The upper part of the back can be used as a luggage space, and a seat I/movement regulating means is provided that allows rearward movement of one seat only when the seat back of the other seat is folded forward. A new sheet has been developed.

(Problems to be Solved by the Invention) In order to improve the operability of moving the seat in such a rear seat structure of a vehicle, it is necessary to have a structure in which the direction in which the seat is moved can be easily recognized.

SUMMARY OF THE INVENTION In response to the above-mentioned demands, the present invention aims to provide a rear seat structure that has excellent operability and is suitable for a vehicle such as a commercial vehicle whose purpose is to secure a constant cargo space.

(Means for Solving the Problems) In the present invention, the rear seat is provided with at least two seats divided into left and right parts, and one seat is configured to be movable rearward only when the seat back of the other seat is folded forward. A rear seat structure for a vehicle, comprising: a first holding means for holding the front and rear positions of the one seat; a second holding means for holding the seat back of the other seat in an upright position; A release means for releasing the holding state of the holding means, and an urging means for urging the seat back of the other seat in the forward direction when the holding state is released by the release means. shall be.

(Function) Since the present invention has the above-described structure, the seat back held in the upright position is urged forward by the urging means at the same time as the second holding means is released, and the seat back is pushed forward in the direction of the seat movement operation. is shown.

(Embodiment) An embodiment of the vehicle rear seat structure of the present invention will be described below with reference to the drawings. FIG. 1 is a view of the vehicle 1 seen from above, and a rear seat is provided behind a driver's seat 2a and a passenger seat 2b, so that two passengers can ride in the vehicle.

This rear seat 3 is divided into two seats 3a on the left and right.

This rear seat structure is shown in FIG. One sheet 3a
The seat back 3c and the seat cushion 3d are integrally supported so as to be movable rearward (in the direction of arrow A). Specifically, slider members 5c and 5c' fitted to a lower rail 5b fixed to the vehicle floor la by a bracket 5a are fixed to the bottom of the seat cushion 3d, so that one seat 3a is formed to be able to freely move back and forth. ing.

The other seat Hb has a hinge bracket 3g so that the seat back 3f can be folded forward toward the seat cushion 3e.
is disposed, and when the seat back 3f of the other seat 3b is raised, it prevents the rearward movement of the one seat 3a and also prevents the seat back 3f of the other seat 3b from moving backward.
A seat movement regulating means 6 is provided that allows the one seat 3a to move backward when the seat f is folded forward.

This sheet movement regulating means 6 is formed integrally with the frame 7 of the seat hack 3f of the other seat 3b and is connected to a stopper locking portion 6a that projects toward one seat side and a slider member 50 inside one of the seats h3a. When the other seat 31) is raised, the stopper 6b is engaged by the stopper engagement portion 6a, thereby preventing the one seat 3a from moving backward. However, when the seat back 3f is rotated in the direction of arrow B, the frame 7
The stopper locking portion 6a, which is integrally provided with the seat 3a, also rotates and is removed from the contact position with the stopper 7, and the stopper 7 is unlocked, allowing one seat 3a to move backward (in the direction of arrow A). becomes.

That is, as shown in Fig. 3, the seat hack 3F of the other seat 3b is folded forward to create a cargo space 4' above the seat pack 3f, thereby moving one seat 3a rearward and expanding the seating space. Therefore, it is possible to improve the comfort of the seat while securing a certain amount of cargo space 4, 4' necessary for a commercial vehicle.

In such a rear seat structure, the back and forth movement of one seat 3a is restricted in order to prevent the seat back 3r of the other seat 3b from tipping forward due to vibration while the vehicle is running, and to reliably restrict the movement of the rear seat 3. A first holding means 9a for holding the other seat 3b in a predetermined position and a second holding means 9b for holding the other seat 3b in an upright position are integrally connected to the release lever 10. The following description will be made with reference to FIG. 2, FIG. 4 which is a plan view of one of the seats 3a, and FIG. 5 which is a front view. Note that the lock plate 15 is omitted in FIG. 4.

The second holding means 9b holds the other sheet 3 as shown in FIG.

It consists of a striker I2 which is disposed at a position corresponding to the seat upright of this locking part 11 and is fixed to the vehicle body, and the locking part 11 locks the striker 12 to hold the frame 7 in the seat pack 3f standing position. be.

This lock portion 11 is connected to the release lever 10 by a cable 13.

As shown in FIGS. 6, 7A, and 7B, this locking portion 11 includes a plate llb that is biased in the direction of arrow C by a spring lla, and a plate lid that is biased in the direction of the arrow C by a spring llc. By engaging the hook llf of the plate lid with the striker 12, the frame 7 is locked in the above-mentioned upright position. When the cable 13 is pulled in the direction of the arrow E, the lock portion 11 is activated by the play 1-1. Ib is the support point 11.
It rotates around e in the pulling direction of the cable 12. As a result, the plate 11d is disengaged from the plate 1.1d, and the plate 11d is rotated about the support point 11g to a position where it contacts the stopper llh due to the biasing force of the spring Lie. Therefore, as shown in FIG. 7B, the structure is such that the striker 12 is unlocked.

Further, the first holding means 9a that holds the front and rear positions of one seat 3a and fixes the seat 3a in a predetermined position locks the locking claws 14a and 14b, which are disposed in one direction on the slider members 5c and 5c', into the slider members 5c and 5c'. The slider member has a structure in which the slider member is locked by engaging with an opening in a lock plate 15 disposed along the line 5c' and fixed to the vehicle body. A rotating member L6a is fixed to an insertion portion 10a that is continuous with the release lever 10 that is rotatably provided downward (in the direction of arrow F) and extends toward the rear of the vehicle body. This rotating member 16a has a shape that allows the insertion portion 10a to fit therethrough, and when the release lever 10 is operated, the insertion portion 10a is inserted into the rotation member 16a.
It rotates integrally with 0a, and there is a lock claw 14 at the bottom.
a is provided and is made to protrude toward the plate 15 side.

Both the outer slider member 5C and the inner slider member 5c'
A lock plate 15 and a rotating member 16b having a lock claw 14b protruding toward the plate 15 are provided, and two rotating members 16a and 18 are provided.
b are interlockably connected by a connecting rod 17. Further, the end portion of the cable 13 is fixed to the rotating member 1.6b without bending when the seat back 3r is in the upright state.

When one seat 3a is in the forward position as shown by the chain line in FIG. 8, the lock claws 14a and 14b are engaged with the openings formed in the lock plate 15, thereby being locked and held. .

In this state, when the release lever 10, which is the release means for these holding means 9a and 9b, is pushed down in the direction of arrow F, the first. The holding of the second holding means 9a, 9b is released.

That is, when the release lever 10 is pushed down (in the direction of arrow F), the rotating member L6a rotates to the position shown by the two-dot chain line as the insertion portion 10a rotates. Along with this, the connecting rod 17 is pulled by the arrow G toward the slider portion H5c'.

For this reason, the rotating portion 4418b rotates about the center l[ic to the position indicated by the two-dot chain line, and accordingly, the cable 13 is pulled toward the slider member 5c' by an arrow G'.

As the cable 3 is pulled, the engagement between the lock portion 11 and the striker 12 is disengaged as described above.

Therefore, the other seat 3b is unlocked.

Further, a biasing means 19 made of a spring as shown in FIG. 2 is disposed in the hinge bracket 3g of the frame 7 so as to tilt the seatback 3f forward (in the direction of arrow B).
Since the frame 7 is biased, at the same time as the lock is released, the frame 7 is biased by the biasing means 19 in the direction of the arrow B as shown by the solid line in FIG. 8, and rotates elastically.
The direction of operation movement is indicated.

When the seat back 3r of the other seat 3b is folded forward in this manner, the movement restriction of the one seat Ha by the seat movement restriction means 6 described above is released. At the same time, due to the rotation of the rotating members lea and 16b as described above, the lock claws 14a and 14b are removed from the fitting position with the opening of the lock plate 15, so that the slider members 5c and 5c are removed.
' is unlocked and one of the seats 3a becomes able to move forward and backward. Therefore, the seating space can be expanded by pushing one seat 3a rearward as shown by the solid line in FIG. In addition, if the openings of the lock plays H and 5 are provided at several locations on the rear side of the vehicle body of the plate 15, the rear position of one of the seats 3a can be set arbitrarily. That is, after performing such a release, the release lever lO

It is easier to operate if you set it up.

In the embodiment described above, only the other seat 3b is provided with the biasing means 19 for instructing the direction of the seat movement operation when unlocking, but the biasing means 19 for instructing the forward and backward movement of one seat 3a is also provided. It is preferable to provide one. Such an embodiment will be described below.

Note that members having functions similar to those in the middle of the drawings are designated by similar numbers.

A second embodiment of the rear seat structure shown in FIG. 9 is comprised of a rear seat structure substantially similar to that shown in the first embodiment, but with a different biasing means 20. This biasing means 20 is different from the biasing means 19 of the first embodiment in that it can instruct the movement direction of both seats 3a, 3b when the first and second holding means 9a, 9b are released. Yes, this floor plan is the first
Shown in Figure 0.

The biasing means 20 includes a spring 22 wound around a spring guide 21 fixed to the vehicle body by a fixed portion 21a. The rear end of this spring 22 is fixed to a fixing plate 23 provided on the rear side of the vehicle body of the spring guide 21, and the fixing plate 23 is connected to the slider member 5c'.
It is fixed by welding, etc. The front end of this spring 22 is connected to the frame 7 via a connecting rod 24. One end 24a of this connecting rod 24 is fixed to the frame 7, and the other end 24b is attached to a holding part 2 provided at the front end of the spring 22.
It is rotatably supported by 2a.

As shown by chain lines in FIG. 8, first and second holding means 9a,
When one seat 3a is held in the forward position by 9b and the seat back 3r of the other seat 3b is held in the upright position, the other end 24b of the connecting rod 24 is held in the frame 7 as shown by the solid line in FIG. Since the spring 22 is attracted to the rear side of the vehicle body due to the upright shape, the holding portion 22a of the connecting rod 24 applies pressure to the spring 22, and the spring 22 is in a contracted state. As mentioned above, release lever 1
When the holding of the first and second holding means is released due to the operation 0, the spring 22 elastically expands in the directions of the arrows H and H' and urges the fixing plate 23 and the holding portion 22a. Therefore, the connecting rod 24 is pushed forward as shown by the dotted chain line, and the frame 7 is elastically moved in the forward direction, thereby indicating the seat movement direction of the seat back 3f. For this reason, the sheet movement regulating means 6
The prevention of rearward movement of one of the seats 3a is released, the locking of the stopper 6b is released, and the slider member 5 integrated with the fixing plate 23 is pressed by the spring 22 against the fixing plate 23.
c' moves elastically backward, and the direction of movement of one seat 3a is instructed.

By further stretching the spring 22 to the position shown by the two-dot chain line, the seat back 7 of the other seat 3b and the one seat! - 3a can be easily moved to the final position (double-dashed line) in each movement direction.

(Effects of the Invention) The vehicle rear seat structure of the present invention includes a first holding means for holding the front and rear positions of the one seat, and a second holding means for holding the seat back of the other seat in an upright state.
a release means for releasing the holding state of the first and second holding means; and a lever stage for urging the seat back of the other seat in the forward direction when the holding state is released by the release means. Since the present invention is characterized in that it is equipped with the following, it is possible to easily recognize the direction in which the seat back of the other seat is operated, and operability is improved.

Furthermore, since the present invention has a rear seat structure in which one seat can be moved backward only when the seatback of the other seat is moved, it is possible to simultaneously satisfy the advantages of securing a certain amount of luggage space and improving seat comfort. Furthermore, the present invention is very effective in that it is possible to improve the operability as described above while ensuring that the seat is held in a predetermined position by the holding means.
