Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a vehicle seat device, and particularly to a vehicle seat device suitable for sleeping on the seat.

<<Prior Art>> FIG. 3 shows an example of a conventional vehicle seat device.

In FIG. 3, seats 1 and 2 are installed in the front and rear of the vehicle, and at least the seat back 3 of the front seat 1 is constructed so that it can be tipped backwards by operating a reclining device 4, as shown by the dashed line in FIG. There is. If you want to take a rest or take a nap in the car, you can do so by reclining the seat.

<<Problems to be solved by the invention>> However, in the conventional structure, the headrest 5 of the front seat 1 is connected to the rear seat 2 when reclining.
The seat cushion 6 cannot be fully reclined. For this reason, the headrest 5 had to be removed each time, which was troublesome. In order to solve this problem, for example,
As can be seen in Japanese Patent No. 52-46423, there is a structure in which a part of the seat cushion 6 of the rear seat 2 is folded back and released, the seat bag 3 is placed in the recessed part, and the folded part is used as a pillow. Proposed. However, even in this structure, the downward rotation is restricted by the seat cushion 6 of the rear seat 2, so the adjustment range is small, and the seat back 3 cannot be sufficiently adjusted to a desired position.

The present invention was developed in view of the above problems, and provides a vehicle seat device that has a structure that allows for a large space in the rear of the seat back and allows the seat to be adjusted to fall until it touches the floor even with the headrest attached. The purpose is to provide.

<Means for Solving the Problems> In order to achieve the above object, the present invention is a vehicle seat device in which seats are installed at the front and rear inside the vehicle, and at least the seat back of the front seat can be tipped backwards. A seat cushion of the seat is provided so as to be reversible toward the seat back side of the rear seat, and a blind device that can be deployed when the seat cushion of the rear seat is reversed is provided on the left and right sides of the lower surface of the seat cushion of the rear seat, The seat cushion of the rear seat can stand up along with the seat back of the rear seat when the seat cushion of the rear seat is reversed. <<Operation>> According to the above configuration, when the seat cushion of the rear seat is reversed toward the seat back side and released, a space is formed at the rear of the seat back of the front seat, and this space is used to move the seat cushion of the front seat. can fall until it hits the floor while wearing a headrest. Therefore, the range of fall adjustment is expanded, and it can be adjusted to the desired position.

<<Example>> Hereinafter, an example of the present invention will be described using the drawings.

FIGS. 1 and 2 schematically show the structure of the main parts inside an automobile to which a vehicle seat device according to an embodiment of the present invention is applied.

In FIGS. 1 and 2, the vehicle seat device includes a pair of front seats 12 located on the left and right sides of the front of a vehicle,
A rear seat 13 is arranged on the rear side.

Each front seat 12 includes a seat cushion 16 attached to the floor 15 via a seat adjuster 14, a seat back 18 attached to the seat cushion 16 so as to be able to fall down via a reclining device 17, and 18 and a head rest 19 attached to the upper part of the headrest 18.

On the other hand, the rear seat 13 includes a seat back 21 fixed on the floor 15 and a seat cushion 22 reversibly attached to the floor 15 via a hinge 20. The seat cushion 22 can be folded into a state in close contact with the front surface 23 of the seat bag 21 by inverting the seat cushion 22 upward using the hinge 20 as a fulcrum.

Further, on the lower surface 25 of the seat cushion 22, blind devices 24 are provided on the left and right sides corresponding to the front seat 12.
are provided for each. This blind device 24 includes a recess 26 provided on the lower surface 25 of the seat cushion 22.
Usually stored within. Then, when the seat cushion 22 is turned over toward the seat back 21 and is in the folded state, it can be pulled out from within the recess 26 and unfolded for use.

In the vehicle seat device configured as described above, when the seat back 18 of the front seat 12 is not toppled backward, the seat cushion 22 of the rear seat 13 is moved to the floor 15 as shown by the solid line in FIG.
Place it on top and use it as a regular cushion.
When the seat back 18 of the front seat 12 is to be fully reclined rearward, the seat cushion 22 of the rear seat 13 is first flipped upward, and the seat cushion 22 is brought into close contact with the front surface 23 of the seat back 21. to form a space on the rear side of the front seat 12. Next, when the seat back 18 of the front seat 12 is pushed backward, the headrest 19 falls down without colliding with the rear seat 13 until it collides with the floor 15 and reaches a regulated full reclined state. Of course, it can be stopped in the middle of this process.
When the headrest is fully reclined, the blind device 24 is placed in the position corresponding to the headrest 19.
is placed. In this state, a person can lie down and sleep on the front seat 12. Furthermore, if the outside light is dazzling when you sleep, you can pull out the blind device 24 to cover your face with the blind device 24 as shown by the dashed line in FIG. 1 and the solid line in FIG. 2. If you want to return it to its original state again, perform the reverse operation to return it to the state shown by the solid line in FIG.

Therefore, in the vehicle seat device configured in this way, the seat back 18 of the front seat 12,
Alternatively, the seat back 18 can be folded down until the headrest 19 comes into contact with the floor 15, so the adjustment range is widened, the seat can be freely adjusted to a desired position, and the user can take the most comfortable posture.

Note that although the above embodiment discloses a structure in which a blind device 24 is provided on the lower surface 25 of the seat cushion 22, this blind device 24 is not necessarily required.

<<Effects of the Invention>> As explained above, according to the vehicle seat device according to the present invention, it is possible to overturn the seat bag of the front seat backward until it collides with the floor while the headrest is attached. This expands the range in which the device can be adjusted, allowing people to freely fall it to their preferred position and take a rest or sleep in the most comfortable position.

Furthermore, the vehicle seat device according to the present invention allows the seat bag of the front seat to be tipped backward until it collides with the floor while the headrest is attached, thus expanding the range in which tipping adjustment can be performed. This allows the seater to freely tilt it to their desired position and take a rest or sleep in the most comfortable position.

In addition, in the present invention, the seat cushion of the rear seat is reversed and raised along the seat back, and a blind device is installed on the back side of the seat cushion, so that when the seat cushion is raised,
A blind device installed on the back side of the seat can be expanded to block out external light while the seated person sleeps, ensuring a good night's sleep.
