Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle seat that is mounted on a vehicle and is convertible and reclinable.

As shown in FIGS. 1 and 2, a conventional three-way seat 1 for a vehicle is installed on a floor 3 in a passenger compartment 2 of a large vehicle, and its structure is as shown in FIG. This allows passengers to sit facing forward, which is the same direction of travel of the vehicle. However, since the backrest 5 is common, there is a drawback that it cannot be reclined. Further, in the triple seat 1' shown in FIGS. 4 and 5, the backrest 5' is divided and can be reclined by a reclining mechanism 6. However, since it was not convertible, passengers had to ride backwards depending on the direction in which the seat was installed.

The object of the present invention is to provide a high-performance vehicle seat that can be changed according to the direction of travel of the vehicle and can be reclined.

As mentioned above, conventional three-way seats for vehicles have the drawback that those that can be converted cannot be reclined, and those that can be reclined cannot be replaced. Therefore, we believe that a seat that combines these two features can be expected to improve the performance of the vehicle, and the present invention has developed a seat that can be converted and reclined, with the function of reversing the backrest portion and the seat futon portion. It is a seat that can be used as a seat.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Figures 6 and 7 show an overall view of the triple seat, and Figures 8 and 9 show detailed views thereof. The seat 1'' is fixed to the floor 3 of the vehicle via a mounting base 7, and its frame 9 is swingable on the mounting base 7 by a pin 8 that serves as a fulcrum during conversion.The frame 9 has a reversing pin 12. When the inverted futon 11 is rotatably attached and the frame 9 is turned over, the inverted futon 11 is flipped up and inverted by the roller 19 located above the reclining handle 10 and the locking device 10A and engaged with the groove 20 of the inverted futon 11. The reversing futon 11 has a symmetrical shape in front and behind the reversing pin 12, and constitutes a seat cushion and a backrest, and an oil damper 15 is installed between the central part of the reversing futon 11 and the mounting base in order to smooth the reversal and reduce the impact. The frame 9 is provided with an armrest 13 having an armrest locking device 14, and when the frame 9 is turned, the armrest 13 is unlocked and automatically points downward. A pillow 16 and a handle 18 are attached to the upper part, and an interlocking pin receiver 17A and an interlocking pin 17 for connection to the frame 9 of an adjacent seat are provided at the lower part.

First, the operation during reclining will be explained. In the solid line state shown in the figure, when the locking device 10A is unlocked using the reclining handle 10 and pulled upward and the body weight is applied to the rear, the reversible futon 11 reclines smoothly due to the cushioning action of the oil damper 15, as indicated by the two-dot chain line. The position is determined by the locking device 10A. If you want to return to the forward reclining position, release the lock using the reclining handle 10 and push it down, and the push-down force and the return spring built into the oil damper 15 will return it to the solid line state. However, interlocking pin receiver 1
There is a gap between 7A and the interlocking pin 17, so that the adjacent frame 9 does not move when reclining.

Next, when converting, the locking device 10A is left in the locked state and the handle 18
to pull it in the direction of the arrow. Then, the reversible futon 11 is pushed up and reversed by the roller 19 provided in the locking device 10A moving in the groove 20 cut under the reversible futon 11, and when it crosses the dead point, it is on the reversible side. Inverted futon 1 on top of lock device 10A'
1 (the part that used to be the backrest) falls, and the other roller 19 enters the groove 20 of the inverted futon 11, stops at the tip of the groove 20, and is positioned as shown by the dotted line. In this case, when the inverted futon 11 starts to invert, the armrest 13 locks the armrest locking device 1.
4 automatically comes off and rotates downward around the armrest locking device 14. Therefore, when in use, if it is lifted and positioned again using the armrest locking device 14, it will be in the state shown by the dotted line, and the top and bottom sides will be reversed from the state shown by the solid line.

For triple simultaneous conversion, interlocking pin 17 and interlocking pin receiver 1
Force is transmitted and converted between adjacent frames 9, 9 via 7A. Therefore, the interlocking pin 17
By changing the state of engagement between the pin receiver 17A and the interlocking pin receiver 17A, it is possible to make it an individual type or a double type on either the left or right side. Moreover, it can also be installed in advance as a two-unit system.

Since the armrest 13 and the pillow 16 are used vertically and front and rear, they are vertically and horizontally symmetrical. With the above functions, the seat can be turned over and reclined, making it possible to achieve high performance.

According to the present invention, a vehicle seat can be provided with both converting and reclining functions, which were conventionally available only separately, and the performance of the vehicle seat can be greatly improved. In addition, they can be used individually, in pairs, or in triplicates without any modification.
