As a result, the lock lever 17 is given the tendency to rotate counterclockwise in FIG. Further, the lock lever 17 is formed with an upper lock groove 19 and a lower lock groove 20 that are spaced apart vertically, and either of these lock grooves 19 or 20 is engaged with the lock pin 5 by the action of the spring 18 described above. can do.

On the other hand, as shown in FIG. 2, the rotating means 7 has the aforementioned lower disk 13 fixed to the upper end of the movable column 12, and the upper disk 21 fixed to the bottom surface of the seat cushion 2, and between these. It has a plurality of rollers 22 arranged,
The upper and lower disks 13.degree. 21 are connected via a center pin 23 located at the center thereof, and the upper disk 21 can freely rotate around the center pin 23 with respect to the lower disk 3. Such a rotating means 7 is conventionally known as a turntable.

Further, as shown in an enlarged view in FIG. 2a, the locking pin 2G is fitted into the locking hole 29.30 formed in the lower disk 21.13 so as to be slidable in the axial direction. Stop pin 26
A compression coil spring 28 wound around the locking pin 26 is disposed between the spring receiver 27 fixedly attached to the upper disk 27 and the upper disk 2. As a result, the locking pin 26 is urged to the right in FIGS. 2 and 2a, and the tip of the locking pin 26 can be engaged with the locking hole 30 of the lower disk 13.

The configurations of the elevating means 6 and the rotating means 7 are as described above,
In addition, assistant seat 1 to seat 1 and driver seat 1a
are each provided with reclining means 31, 31a (FIG. 1) for tilting the seats 3, 3a rearward. These reclining means 31.31a are well known per se, and therefore a detailed explanation of their construction will be omitted.

During normal use of assistant seat 1 and driver seat la, these seats f, 1. la faces forward as shown in FIGS. i and 2, and the locking pin 26
is engaged in the locking hole 29.30 of the upper and lower disks 21.13 by the action of the spring 28, and rotation of the upper disk 21 is prohibited. Rotating means 7 on the driver seat 1a side
The same applies to a. Therefore, both seas 1-1. la remains facing forward and is locked in this position. At this time, the assistant seat 1 occupies the lowered position shown by the solid line in FIG. prohibited. FIG. 3(a) shows the state of the movable column 12 at this time. The same applies to the driver seat 1a side.

When the occupant seated on the assistant seat 1 or the driver seat 1a wants to lie down, the lock lever 17 is rotated clockwise in FIG. 2 against the action of the spring 18. As a result, the lock pin ↓5 comes off from the lock groove 20 on the lower side of the lock lever F. Therefore, the movable column 12 is released from the restraint by the lever 17 and becomes free. Therefore, the movable column 12 is pushed upward by the spring mechanism, and the assistant seat 1 is lifted together with its rotating means 7 to the raised position shown by the dashed line in FIG.

The passenger can lie down here.

When tilting seat back 3 in the direction of arrow B, assistant 1
~Since the entire seat 1 is held in the raised position and raised, the seat back 3 does not interfere with the console box 4, etc. Further, since the driver seat 1a is also in the 2-up position, the seats 1 to 2a and the seatbacks 3 of the seats 1 to 1 are substantially continuous and flush.

As described above, the occupant can lie down from the assistant seat 1 or the driver seat 1a without moving his or her body backwards. Furthermore, since the bed surface is formed by the assistant seat 1 and the driver seat la, the above-described configuration can also be applied to a vehicle without a rear seat. Of course, this invention can be applied to both vehicles with and without a nap bed at the rear.

In the illustrated embodiment, since the driver seat 1a is also provided with the rotating means 7a and the reclining means 31a, the driver seat 1a can be rotated toward the seat 1 so that the back surface of the back 3a faces the seat cushion 2 of the assistant seat 1. It is also possible to form a bed surface 1 by tilting the seat back 3a to the rear side, but it is also possible to attach the rotation means to only one of the seats 1 to 1 or la, and to attach the reclining means to the seat provided with the rotation means. Even if this is done, the intended purpose of the present invention can be achieved. The lifting means is for both seats 1. It is necessary to provide it in la.

〔Effect of the invention〕

According to the present invention, a bed surface can be formed by the assistant seat and the driver seat, and the occupant can lie down from the assistant seat or the driver seat without moving his/her body behind the assistant seat or the driver seat.
