DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle seat, particularly a two-way vehicle seat in a one-box car or the like.

Conventionally, as shown in FIG. 1, seats for vehicles such as one-box cars are provided with a first seat 2 and a second seat 3 at the rear of a box 1 in the engine storage area.
A rotation mechanism (not shown) is provided between the legs 4 of the seat 2 and the seat cushion 5 so that the seat 2 can be seated opposite to the second seat 3.

However, with the above-mentioned two-person seats, the occupants can simply face each other,
In addition, the seats in a one-box car usually seat only about three people in a row, so only about six people can sit facing each other.Furthermore, these seats are not equipped with tables or the like, which is inconvenient. Also,
Conventional vehicle seats lack luxury even when seated in a swivel manner, and have the disadvantage that occupants cannot feel comfortable and relaxed.

The purpose of this invention is to divide the front seat and rear seat of a vehicle seat into three parts, and to make the seat cushion part and the seat back part rotatable or slidable respectively, so as to provide a lounge-style chair and table using the vehicle seat.

The front seat 10 is divided into three parts, and the seat back parts 12, 12 of the first divided seats 11, 11 on both sides are reclined to the rear side so that they become horizontal via a reclining mechanism (not shown). , 11a, and cushion bodies 13, 13 are provided on the side walls of the vehicle of the first divided seats 11, 11, respectively.
As shown in FIG. 6, the seat cushion part 15 of the central second divided seat 14 of the front seat 10 has its front end side connected to the upper end of the legs 15m, 15m which are provided upwardly projecting from the floor S. It is pivotally connected via a shaft 15f, and is rotatable in the front and rear directions. In this case, a pin 15x is provided protruding from the side surface of the seat cushion part 15, and when the seat cushion part 15 is rotated forward about the shaft 15f and is in a horizontal state, a notch in the leg 15m The seat cushion portion 15 is locked to the seat cushion portion 15n.
maintains a horizontal state. This second divided sheet 14
The bottom side of the seat cushion portion 15 is also a cushion body on which the user can sit. Normally, the seat cushion part 15 has a leg 15m long.

Further, as shown in FIG. 3, pins 20 are provided on both sides of the lower side of the seat back portion 16 of the seat cushion portion 15, and these pins 20 are provided on the rear side of the adjacent seat cushion portions 11a, 11a. The seat back part 16 can be moved upward by engaging with the guide groove 17 of the guide plate 18, which is positioned so that the tip side thereof protrudes toward the ceiling. A third lock portion L3 is provided to hold the seat back portion 16 in a horizontal state when the seat back portion 16 is rotated forward and reversed, and furthermore, the seat back portion 16 can be rotated vertically so that the seat back portion 16 can be seated. A fourth lock portion L4 for holding is provided. Note that the guide plate 18 has a pin 19 at the lower end, and the seat cushion portions 11a on both sides are connected via this pin 19.
It is pivoted to the 11a side and can be rotated to a substantially upright position, and is locked in the substantially upright position by a locking means (not shown). Note that this guide plate 18 may be fixed while maintaining a substantially upright position. The pins 21 on both sides of the seat cushion portion 16 are engaged with the notches 18a and held in a horizontal state, thereby forming the third lock portion L3. Also, pin 22
A fourth lock portion L4 is configured, which is engaged with the notch portion 18a to maintain a vertical position in which the seat can be seated.

The rear seat 30 is also divided into three parts, and the seat cushion parts 32, 32 of the first divided seats 31, 31 located on both sides are the first part of the front seat 10.
When the seat back portions 12 of the divided seats 11, 11 are folded back, they are continuous without any gap, and the seat cushion portion 3 of the second divided seat 33 in the center
As shown in FIGS. 4a and 4b, the rear side of 4 is connected to the seat cushion portion 3 of the first divided seats 31, 31.
One end of the link rod 36 is rotatably connected to the side surface of the front end of the link rod 36 with a pin 35, and the other end of the link rod 36 is pivotally connected with a pin 37, and a notch is provided at the lower end of the link rod 36 near the pin 37. A fixing pin 38 is provided on the upper side of the link rod 36 of the seat cushion portion 34 at an equal distance from the notch 36a around a pin 37. A pin 3 protruding from the side surface of the seat cushion portion 32 is provided to hold the link rod 36 in an almost upright state with a slight forward inclination.
A lock portion L5 is configured. Further, the pin 38 and the notch 36a constitute a sixth lock portion L6. Further, the bottom surfaces of the seat cushion portion 34 and the seat back portion 16 are formed into tables 34a and 16a made of a hard member. Further, the second divided seat back portion 40 is connected to the seat back portions 32a, 32a of the adjacent first divided seat through a reclining mechanism (not shown), and can be rotated toward the rear side to maintain a horizontal state. There is.

With the above configuration, the operation of the vehicle seat according to the present invention will be explained. In normal use, as shown in FIG. When using the front seat 1 as a lounge-style seat, as shown in Figure 5,
The seat back parts 12, 12 of the first divided seats 11, 11 of No. 0 are folded backward, the seat cushion part 15 of the second divided seat 14 is rotated and reversed forward, and the cushion body on the bottom side is positioned upward; The seat back part 16 of the second divided seat 14 is slid upward and rotated backward to maintain a horizontal state, and the table 16a on the back side of the seat back part 16 is fixed upward. Next, the link rod 36 of the seat cushion part 34 of the second divided seat 33 of the rear seat 30 is linked forward, and then the seat cushion part 34 is rotated and reversed, so that the table 34a on the bottom side faces upward and remains stationary. , and further the second divided sheet 3
The seat back portion 40 of No. 3 is tilted backward and held in a horizontal state. By doing this, at least eight people can surround the tables 16a, 34a in a circle and have a chat, resulting in a lounge-style vehicle seat that is much more usable than a two-person seat.

As explained above, according to the vehicle seat according to the present invention, the front seat and the rear seat of the vehicle seat are each divided into three parts, and the seat cushion part and the seat back part are respectively rotatable or slidable to form a lounge-style vehicle seat.
