Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat device.

[0002]

2. Prior Art and Problems to be Solved by the Invention
As a seat device for a passenger, a so-called bench seat having a seat cushion and a seat back with a width for three, a seat cushion with a width for one seat and a seat for one seat, and a two-seater Seat device of a so-called 1.5-divided seat, which is divided into a seat cushion of a width for two persons and a seat for a seat back, and a seat cushion of a width for one person and a seat for one person of a seat back. A sheet device in which three of these are arranged is known. Also, in these seat devices,
It is also known that each seat cushion is supported by a slide mechanism that can slide back and forth.

The bench seat has the advantage that it has a small number of parts and can be constructed at low cost.
When sliding back and forth, there is no choice but to slide back and forth as a whole. In this structure, since the seat device is integrally configured, the divided seats are individually moved to move from the seats in the second row to the rear seats. I couldn't walk through to the seat because I couldn't secure a passage to walk through. Therefore, it has been desired to realize a walk-through between front and rear seats in order to improve convenience in the room.

Therefore, the seats in the second row are divided into three parts having the same width in the vehicle width direction, and the central seats of the seats in the second row are installed slidably in the front-rear direction. There has been a structure in which it is housed between the driver's seat of the row seats and the seat cushions of the passenger seats to secure a passage for walking through from the seats of the second row to the seats of the third row. In this structure, the width of each of the three-divided seats is narrowed due to the restriction of the limited vehicle width, and it is not possible to secure a comfortable seating space. In addition, there is a problem that the seating space of the driver's seat, which is required to have a sufficient space in view of maneuverability and safety, becomes narrow.

Therefore, in order to secure a seating space for the driver's seat, the seat width of the first row is set to a width that allows a comfortable seat,
The center seat of the second row seat is slidably installed to the rear end of the seat cushion of the first row seat, and the center seat is moved to the rear end position of the first row seat to Some have a structure that secures a passage for walking through from the seat to the seat in the third row.

However, in this structure, when the passage is used, the first row seats and the second row seats are installed with a large front and rear distance so that the central seats do not get in the way. There is a need to. Alternatively, it is necessary to slide the seats in the second row largely backward so as to secure a large front-back distance between the seats in the first row and the seats in the second row. Therefore, there is a problem that the total length of the vehicle becomes long.

Therefore, as a structure for securing a passage for a walk-through by sliding the central seat forward without increasing the distance between the first row seats and the second row seats, Japanese Patent Laid-Open No. 2000- Some are described in Japanese Patent No. 272385. As shown in the plan view of FIG. 6, according to this conventional technique, the central seat 02 between the right seat 021 and the left seat 022 of the second row of seats divided into the same width in the vehicle width direction is divided into three parts.
The seat back of No. 3 is tilted forward, and the seat cushion and the seat back are erected backward together with the seat back on top of the seat cushion. Then, only the base 0231 of the central seat 023 is housed between the seat cushions of the driver seat 011 and the passenger seat 012 of the first row of seats.

However, in this conventional technique,
In order to secure the passage for the walk-through, it is necessary to deform the center seat 023 and slide it forward, which is troublesome and troublesome. Further, since the seat back and the seat cushion are erected together during the walk-through in the central seat 023, when the accessory case is provided, the stored accessory may be scattered, which makes it difficult to provide the accessory case in the center seat. It was

Therefore, as a structure in which the central seat is slid forward from between the seats in the second row and is housed between the seats in the first row, as shown in FIG.
The one described in Japanese Patent No. 7 is known. This prior art is based on the right seat 0021 and left seat 00 of the second row of seats.
The seat cushion of No. 22 has a width that allows a comfortable sitting, and the right seat 0021 and the left seat 00 of the second row seat
The central seat 0023 installed between 22 is slid forward, and the driver seat 0011 and the passenger seat 001 of the first row of seats are slid forward.
It had a structure that could be stored between the two.

However, in this conventional technique,
If the central seat 0023 is fixed between the driver's seat 0011 and the passenger seat 0012 of the first row seat or between the right seat 0021 and the left seat 0022 of the second row seat and three seats are to be seated, the central seat Since the width of 0023 fits between the seat cushions of the driver's seat 0011 and the passenger seat 0012 of the first row of seats having a large width, a sufficient seating space for the central seat 0023 should be secured. There was a problem that it was difficult.

The present invention has been made by paying attention to the above-mentioned conventional problems, and secures a sufficient seat width as a driver's seat and a passenger seat of the first row of seats, and at the center of the second row of seats. The seats in the second row to the third row are seated even if the necessary seat width is secured for each of the seats including the seats and the front-back seats are not widened in the front-rear direction. It is an object of the present invention to provide a vehicle seat device capable of performing walk-through up to and including a simple operation and improving convenience.

[0012]

In order to achieve the above object, the present invention provides, behind a first row of seats (1) provided with a driver's seat (11) and a passenger seat (12), A seat (2) of a second row is provided, and the seat (2) of the second row is arranged in the vehicle width direction, and includes a right seat (21), a left seat (22), and the right seat (21). And a central seat (23) narrower than the left seat (22),
In a vehicle seat device in which the central seat (23) is slidably supported on a floor of a passenger compartment through a slide means, a seat cushion (111) of the driver seat (11) and the passenger seat (12). The width of the rear portion of the seat cushion (121) is smaller than the width of the front portion, and the seat cushion (111) of the driver seat (11).
And the seat cushion (1) of the passenger seat (12)
21) The rear part of the storage space (13) formed between the rear seat and the rear seat is formed slightly wider than the central seat (23).
When the central seat (23) is slid forward,
The vehicle seat device is characterized in that the front portion of the seat cushion (231) of the central seat (23) can be stored in the storage space (13).

In the invention according to claim 2, when the central seat (23) is aligned with either the right seat (21) or the left seat (22), the two seats are combined into two. The feature is that the width is formed so that a person can sit down.

[0014]

According to the first aspect of the invention, the second row of seats is provided behind the first row of seats where the driver's seat and the passenger seat are provided, and the second row of seats is provided. A right seat, a left seat, and a central seat that is narrower than the right seat and the left seat are arranged side by side in the vehicle width direction, and the central seat is front and rear through slide means on the floor of the passenger compartment. In a vehicle seat device slidably supported on the vehicle seat device, a rear portion of the seat cushion of the driver seat and a seat cushion of the passenger seat is formed to be narrower than a front portion thereof, and a rear portion of the seat cushion of the driver seat. And a rear portion of the seat cushion of the passenger seat, the width of the storage space formed between the central seat and the rear is slightly wider than the width of the central seat, when the central seat is slid forward, Sheet of The front of the ® emission lies in the possible received in the receiving space.

For this reason, when performing a backward walk-through from the seats in the second row, the central seat, which is narrower than the left and right seats in the seats in the second row, is the driver seat only at the front of the seat cushion. In the second row of seats, the seats in the second row are slid forward until they are inserted into the accommodation space provided between the seat cushions of the passenger seats, and between the front end portions of the left and right seats and the rear end portions of the central seats, and the left and right seats. A space for a walkthrough is formed between the two so that the walkthrough can be performed.

As described above, at the time of walk-through, the walk-through can be achieved only by sliding the central seat of the second row of seats forward, and the operation for folding or standing up the central seat is not necessary and the operability is excellent.

Further, in achieving the walk-through as described above, the central seat, which is narrower than the left and right seats of the second row of seats, has only the front portion of the seat cushion only for the driver's seat and the assistant of the first row of seats. Since the seat is stored between the rear part of the seat cushion and the whole central seat is not moved between the driver's seat and the passenger's seat, the seat width is narrowed in the driver's seat and the passenger's seat, especially in the driver's seat. The seat width can be prevented and the seat width sufficient to take the driving posture can be secured without widening the vehicle width.

That is, with respect to the driver's seat, the driving posture is such that both legs are lightly opened to the left and right, and in this posture, the seat width required to support the buttocks and thighs with the seat cushion is thighs. The front part of the seat cushion that supports the lower part needs a wider width, but the rear part of the seat cushion that supports the buttocks does not require a wider seat width than the front part. Therefore, ensure a sufficient seat width for taking a driving posture, and provide a storage space for storing the front part of the center seat of the second row of seats between the rear part of the seat cushions of the driver's seat and the passenger seat. It is possible to achieve both.

Further, the central seats of the seats in the second row are arranged such that the front part thereof overlaps with the seats in the first row in the vehicle front-rear direction during the walk-through, so that the seats in the first row and the seats in the second row are arranged. The distance between the seat and the seat in the front-rear direction is shorter than the size of the front-rear length of the central seat plus the front-rear length of the space for walk-through, and the walk-through can be achieved. It does not require a wide front-to-back space with the seat.

According to the second aspect of the invention, the center seat of the second row of seats has such a width that two seats can be seated together when they are aligned with either the right seat or the left seat. It has been formed.

Therefore, the seats in the second row can be seated by one to three people when the seats are used side by side, and when one of the left and right seats is independently slid back and forth. Even if there are three seats in the second row, a total of three people can be seated, and the number of seated passengers does not decrease.

The second row of seats is for one person or two people.
In the case of a person, the left and right seats having a sufficient seat width for one person can be comfortably seated.

As described above, according to the present invention,
The seat width required for the driver's seat and the passenger seat is ensured and the seat width required for each seat of the second row is ensured in the limited vehicle width and the vehicle longitudinal length. Even if the longitudinal distance between the seats in the second row and the seats in the second row is not set wider than the front-rear length of the seats in the second row, the walk is performed by simply sliding the center seat of the seats in the second row forward. It is possible to obtain the effect of being able to provide a new vehicle seat device that can achieve through.
