Abstract

PURPOSE:To permit the selective use of a bench type seat and separation type seat by allowing the right and left independent seats to be aslantly slided so as to be positioned to the center side of the car body as the seats are set forwardly and connecting the right and left independent seats at the forwardly slided position. CONSTITUTION:Each independent seat 3R, 3L, 4R, and 4L can be slided, and at the rearward slided position, the right and left independent seats 3R, 3L and 4R, 4L of the seats S2 and S2 are set apart. When the independent seats 3R, 3L, and 4R, 4L are slided forward from this state, these seats are set into the advance slide position. At this position, the right and left independent seats 3R, 3L and 4R, 4L are connected, and one bench type seat is constituted. Therefore, the seats behind a driver's seat can be switched selectively into a connected bench type seat and a separation type seat.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an automobile seat device.

(Prior Art) Seats in automobiles, particularly one-box type automobiles, are often designed to be usable for multiple purposes. For example, in a vehicle that has two rows of seats behind the driver's seat, the front seat can be turned rearward at will, so that those seated in the front and rear seats can face each other. be. Furthermore, as shown in Japanese Patent Application Laid-Open No. 61-37547, the seat on the side of the entrance/exit for the seat behind the driver's seat is divided into left and right configurations, and the split seat on the entrance/exit side of this divided seat is horizontally divided. Some vehicles are designed to be able to slide in different directions, making it easier to get on and off the vehicle. Recently, there have been an increase in the number of cars in which the front row seat where the driver's seat is located and the seat to the right of the driver's seat form a large continuous flat surface (flat seat).

(Problem to be Solved by the Invention) By the way, for example, the seat behind the driver's seat in an L-box car is composed of a pair of left and right independent seats that are widely spaced from each other in the left and right direction in order to ensure a comfortable sitting position. While there are some types, there are also bench types that are continuous in the left and right direction to provide a flat seat or to seat three people.

In this case, it would be more convenient if it were possible to arbitrarily switch and select between the separated type separated left and right and the bench type continuous left and right. In order to realize this idea, it is conceivable to make the independent sheet slidable in the left and right direction. However, in the case of a bench type, it is desirable to have a relatively forward position (closer to the M transfer seat) in order to create a flat seat, while in the case of a left and right separated type, it is desirable to have a relatively forward position (closer to the M transfer seat). It is desirable to have a large foot space, that is, to position the vehicle at a rear position relatively far from the driver's seat. Therefore, it is impossible to satisfy the above-mentioned requirements simply by sliding the left and right independent sheets in the left-right direction.

The present invention was made in consideration of the above circumstances, and
It is an object of L1 to provide a seat device for an automobile in which the seat behind the driver's seat can be made into a bench type in the forward position, and can be made into a left-right separated type with a large distance left and right in the rear position. shall be.

(Means and operations for solving the problems) In order to achieve the above-mentioned object, the present invention has the following configuration. In other words, the seat located behind the driver's seat is
It is a separate type with a left independent seat and a right independent seat that are independent of each other, and the left and right independent seats can be slid diagonally toward the center of the vehicle as they move forward, and in the rear sliding position. The left and right independent seats are left and right separated from each other by a large distance, and at the forward sliding position, the left and right independent seats are connected to form one bench seat.

With this configuration, a bench-type seat can be obtained in the forward position by the extremely simple operation of diagonally sliding the independent seat, and a separate type with a large distance left and right in the backward position can be obtained. be able to.

(Example) Examples of the present invention will be described below based on the attached drawings.

In Fig. 1, a car A, which is an l-box type, has a first row seat S1, a second row seat S2, and a third row seat S3 on its floor surface F) from the front side of the vehicle body to the rear side. have.

As shown in FIGS. 2 and 3, the first row of seats S1 includes a driver's seat 1 and a passenger seat 2 for two people. Seats s2 and S3 in the second and third rows are left independent seats 3L and 4L and right independent seats 3, which are independent from each other on the left and right.
It is composed of R14R. Each independent sheet 3L, 3
R14L and 4R include a seat cushion 5 and a seat back 6, as well as a pair of left and right armrests 7. Then, the independent seats 3L and 3R of the second row seat S2
are respectively attached to the floor surface F via the known rotary base 8 (see Fig. 1 and Fig. 6), so that the Both positions can be taken arbitrarily.

The armrest 7 is constructed by dividing the left and right end portions of the seat back 6, and is rotatably connected to the side surface of the lower end portion of the seat back 6. As a result, it can take a forward position (see FIG. 4) that functions as an armrest and an upright position (see FIG. 5) that functions as a seat back. In order to prevent the armrest 7 from falling backward relative to the seatback 6 when it functions as a seatback, for example, locking pins for supporting the armrest 7 may be provided on both sides of the seatback 6, which can be freely retracted. Alternatively, locking step portions may be formed on both sides of the seat back 6 to partially support the back surface of the armrest 7. The armrest 7 is placed on the seat cushion 5 in its forward position where it functions as an armrest. In other words, the overall width of the seat back 6 and both armless doors is set to be approximately the same as the width of the seat cushion 5.

Each independent sheet 3R13L, 4R14L is
In the forward facing position shown in the figure, it is slidable in the direction shown by the arrow. That is, Figure 2 shows the forward slide position, and Figure 3 shows the rear slide position, and as the independent seats (3L, 3R, 24L, and 4R) move forward, they move toward the center of the vehicle body. .

In the above configuration, the independent sheets 3L, 3R14
In the state shown in FIG. 3 in which L and 4R are in the rear slide position, the left and right independent seats 3L and 3R of the seats S2 and S3 and the left and right independent seats 3R and 4L and 4R are largely separated from each other in the left-right direction.

At this time, the distances between the left and right independent seats 3L and 3R and between 4L and 4R are from the first row seat Sl to the third row seat S1.
It becomes the movement path X for the passengers up to S3. In this state, the independent seat 3 of the second row seat S2 is
A large amount of leg space is secured in the L and 3R directions in the front and rear directions. Moreover, as shown in FIG. 4, the user can fully relax by using the art rest 7.

From the state shown in Figure 3, move the independent sheets 3L and 3 in the direction of the arrow in the figure.
When R14L and 4R are slid, the forward slide position shown in FIG. 2 is achieved. In this position, the left and right independent seats 3L
, 3R, 14L, and 4R are connected to each other to form one bench type seat. Of course, at this time, at least the armrest 7 on the center side of the vehicle body is in the upright position and functions as a seat pack. in this case,
It is possible to seat three people.Also, since it is close to the first row seat Sl, with all the armrests 7 in the upright position, the seat packs in the seats 51, S2, and S3 of each row A so-called full flat seat is constructed by tilting the seat 6 backward until it is almost horizontal.

In addition, in the rear sliding position shown in FIG. 3, by making the amount of rearward sliding of the third row seat 53 larger than the rearward sliding amount of the second row seat S2, the leg space in the third row seat S3 can be reduced. You can also make it bigger. If the slide hardness is to be different, the inclination angle in the slide direction may be set so that the left and right positions of the seats S2 and S3 in the second and third rows are the same at the rear slide position.

A specific example of making the independent seat slidable as described above will be explained with reference to FIG. 6, focusing on the independent seat 3R. In FIG. 6, a pair of guide rails 1 are mounted on the upper base frame ll of the rotating base 8.
2 are configured. This guide rail 12 consists of an upper rail 12a and a lower rail 12b that are slidably fitted together as is known, the lower rail 12b is fixed to the upper surface of the upper base frame 11, and the upper rail 12a
is fixed to the lower surface of the frame of the independent sheet 3R (not shown). Such a guide rail 12 is inclined at an angle θ with respect to the longitudinal direction of the vehicle body.
2 is the sliding direction shown in FIGS. 2 and 3.

In addition, 13 in FIG. 6 is the lower base frame (
(7 base frames 11 are horizontally rotatably connected), and 14 is a cable for operating a locking mechanism for locking and unlocking the slide of the independent seat 3R at least at its front and rear stroke ends. be.

FIG. 7 shows an example of application of the present invention, in which the third row seat S
3 is also made horizontally rotatable using a rotating base 8. In this case, each independent sheet 3L,
Using the rotation of 3R14L, 4R and the slide by the guide rail 12, each independent seat is turned toward the side of the vehicle body, while the rear independent seats 3L, 4L are moved toward the vehicle body with respect to the front independent seat 3R14R. It is designed to be offset in the front and back direction. Let me elaborate on this point.

For the right independent seats 3R and 4R, space for their feet can be ensured by sliding corresponding to the backward slide position while facing the -side a1 (securing the space between them and the side wall al). In addition, left independent seats 3L and 4L
, by sliding from the rotational position yE (broken line in Figure 7) toward the side wall al, which corresponds to the forward slide position, the foot space can be secured and the right independent seat 3L,
The front view (view through the window on the side wall AL) is secured without being obstructed by 3R.

(Effects of the Invention) As is clear from the above description, the present invention allows the seat behind the driver's seat to be selectively switched between a bench type that is connected to the left and right and a separate type that is widely separated from the left and right. .

In addition, when selecting the bench type and when selecting the separated type, the front and rear positions are optimally set, and the bench type is preferable for creating a flat seat, and the separated type is preferable for securing leg space. becomes.
