Abstract

PROBLEM TO BE SOLVED: To form a simplified bed by rotating a seat whose recessed part stores a seat frame for changing its direction and forming a wide luggage compartment. SOLUTION: The first recessed part 12a is formed at the front end of a floor panel higher than the front, and the first seat cushion is stored through the first seat frame 21a. This structure is provided with a moving means 41 for locating the first seat frame 21 a vertically, a rotating means 61 for conducting horizontal rotation, and a fixing means 71 for fixing its movement and rotation. The moving means and the rotating means consists of a shaft 13 vertically-mounted on the seat frame and a shaft case 14 embedded in the recessed part. The fixing means is preferably constituted of an annular groove 13a, a hole to be locked, and a locking pin formed in the shaft, and a pin inserting/removing means for inserting and removing the locking pin. By forming the first and second seat frames roughly flush with each other, a bed plate may be bridged over the seat frames.

The shaft 13 is inserted into the shaft case 14 via an auxiliary spring 15. Auxiliary spring 1
5 has a force slightly larger than the force for supporting the second seat 21, and biases the shaft 13 so as to push it up when the shaft 13 is inserted. Accordingly, the first seat frame 21a can be easily moved up and down, and is supported rotatably in the horizontal direction with respect to the floor panel 12. As shown in FIG. 3, the fixing means 71 includes an annular groove 13a provided in the shaft 13 and locked holes 13b, 13b, a locking pin 71a configured to be inserted into and removed from the locking hole 13b, and the locking pin 71a. It is composed of a pin insertion / removal means 72 for inserting / removing the locking pin 71a. Locking pin 71a
Is made of a steel material having sufficient strength and is configured to be inserted into or removed from the annular groove 13a or the locked hole 13b of the shaft 13 by penetrating through the pin hole 14b provided in the side portion of the shaft case 14. To be done. The locking pin 71a is configured to regulate the height and rotation of the first seat frame 21a (FIG. 1) when inserted in the locked hole 13b of the shaft 13 and to allow the movement thereof in the disengaged state. The insertion / removal of the locking pin 71a is performed by the pin insertion / removal means 72.

The pin insertion / removal means 72 is shown in FIGS. 1 and 2 in which a spring 73 is urged to insert the locking pin 71a into the annular groove 13a or the locked hole 13b and the locking pin 71a is pulled out. And a knob 74. The knob 74 is provided on the floor panel 12 at the front end of the first recess 12a and is configured so that an occupant can operate it with his / her hand. One end of a wire 74a is fixed to the knob 74, and the knob 74 is connected to the locking pin 71a shown in FIG. 3 via the wire 74a. Wire 7
The other end of 4a is fixed to a locking pin 71a inside the pin case 71b, and the locking pin 71a is adapted to interlock with the movement of the wire 74a. The wire 74a is protected by the coating tube 74b, and the coating tube 74b is locked to the pin case 71b. The locking pin 71a is provided with a disk-shaped stopper 71c, and a spring 73 for urging the locking pin 71a to be inserted into the annular groove 13a or the locked hole 13b is provided between the stopper 71c and the pin case 71b. It is provided.

The above-mentioned first seat frame 21a and second seat frame 31a are moved upward and fixed by the fixing means 71.
In the state of being fixed by, they are configured to have substantially the same height. On the other hand, as shown in FIG.
A storage member 92 is provided on the ceiling 10a of 0, and the storage member 92 stores a bed plate 91 of a size that can be passed over the first seat frame 21a and the second seat frame 31a. Although not shown, the bed plate 91 is a plywood made of lightweight wood, and a thin cushion material is attached to the surface thereof. The storage member 92 is provided with members having an L-shaped cross section at four positions on the ceiling, and the squares of the bed plate 91 are hooked at their ends to be stored on the ceiling 10a of the vehicle 10. Bed plate 91 is the first when used
It is hung over the seat frame 21a and the second seat frame 31a via the first seat cushion 21b and the second seat cushion 31b so that the occupant can sleep on it, and when not in use, the storage member 92 is used. It is configured so that it can be stored on the ceiling 10a of the vehicle 10.

In the vehicle seat mounting structure thus configured, the locking pin 71a is disengaged from the locked hole 13b of the shaft 13 when the occupant pulls the knob 74 which is the pin insertion / removal means 72, and the shaft 13 Is the shaft case 14
It is possible to freely move and rotate inside. In this state, the occupant moves or rotates the second seat frame 21a up and down to position the second seat frame 21a at a desired position. After the second seat frame 21a is positioned at the desired position, the knob 74 is returned with the locked hole 13b at that position corresponding to the locking pin 71a. When the knob 74 is returned, the spring 73 provided in the pin case 71b
Attaches the locking pin 71a to the locked hole 1 via the stopper 71c.
Bias to insert into 3b. The locking pin 71a is inserted into the locked hole 13b by the bias of the spring 73 to prevent the shaft 13 from moving and rotating. As a result, the second seat 21 is fixed in that state. The usage state of the vehicle having the second seat 21 and the third seat 31 will be described below.

As shown in FIG. 6, by moving the third seat 31 upward and raising the second seat back 21c, many passengers can board. Also,
As shown in FIG. 7, when the occupant is absent, the third seat 31 is stored in the second recess 12b, and the seat cushion 21b of the second seat 21 is erected to raise the seat back 21.
By laying down c, the luggage compartment at the rear of the vehicle can be enlarged. Further, as shown in FIG. 8, when an occupant is boarding, the third seat 31 is moved upward to erect the second seat back 31c, and the second seat 21 is moved upward and rotated by 180 ° to become a seat for seating. Can be changed. As a result, smooth communication of the occupant on the anti-seat seat while traveling can be achieved. In this case, by providing a table 22 between the second seat 21 and the third seat 31, it can be used as an outdoor living room. Further, as shown in FIG. 9, the third seat 31 and the second seat 21
Is moved upward and positioned at approximately the same height, and the bed plate 91 housed in the ceiling 10a of the vehicle 10 is taken out and hung over the respective seat frames 21a and 31a to easily create a bed for sleeping. can do.

[0017]

As described above, according to the present invention, the moving means for vertically positioning the vehicle seat, the rotating means for rotating the vehicle seat in the horizontal direction, and the movement and rotation of the seat are fixed at predetermined positions. Since the seat has a seat frame in the recess, the seat can be rotated to change its direction by moving the seat upward. However, the height position of the seat does not change. In addition, the seat back is attached to the seat cushion so that it can be laid down, and the back of the laid-down seat back has the same plane as the floor panel, so that it can be used as a contra-seat seat when the occupant is on board, and the occupant is absent. Sometimes it can be a large luggage compartment. Further, the first seat frame and the second seat frame are configured to have substantially the same height by the fixing means in a state where the first seat frame and the second seat frame are moved upward, and the bed plate is hung over the first seat frame and the second seat frame. If so configured, a bed for sleeping can be easily made. As a result, it is possible to secure a bed in which an occupant can sleep even when the luggage is accommodated in the floor panel, and there is also an advantage that it can be used as a camping car.
