Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a passenger seat for an automobile, and is particularly suitable for application to a passenger seat for a truck.

In automobiles, the driver's seat is located off to either the right or left side, resulting in poor visibility for the driver on the opposite side, which causes inconvenience when making a curve to the opposite side of the driver's seat.

For this reason, in large trucks, etc., a small window is installed in the lower half of the door opposite to the driver's seat to prevent visibility from the side opposite to the driver's seat. The disadvantage was that the front part obstructed visibility and did not function adequately.

Therefore, conventional seats of this type have been proposed in which the front part of the seat cushion can be flipped up. The back surface was exposed, which caused problems in terms of appearance quality.

In view of the above, the present invention provides a passenger seat for an automobile, which allows the driver to have sufficient visibility through a small window for visibility when making a curve, without impairing the appearance quality.

That is, the present invention raises the rear part of the seat cushion of the passenger seat and moves it rearward with the front surface of the seat cushion positioned on the front side, so that driving can be performed using a small window for visibility when making a curve. This is to ensure sufficient visibility for the person.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the figure, 1 indicates the entire passenger seat for a car,
2 is a seat cushion, and 3 is a seat bag. This seat bag 3 is connected via a reclining device 4 to a frame 5 fixed to the floor side. The front portion 2a of the seat cushion 2 is provided with a slider 6 that is slidable in the front and rear directions with respect to the frame 5.
It is tiltably supported. That is, brackets 7a and 7b fixed to the lower surface of the front portion 2a of the seat cushion 2 and brackets 8a and 8b fixed to the slider 6 are rotatably connected by a pivot shaft 9. The biasing force of the coil springs 10a and 10b inserted into the pivot shaft 9 causes the rear portion 2b of the seat cushion 2 to jump up with the pivot shaft 9 as the center of rotation.

Normally, the rear part 2b of the seat cushion 2 is controlled by an engaging piece 11 provided on the lower surface thereof being engaged with a catcher spring 12 disposed corresponding to the frame 5 side. The catching force of the catcher spring 12 is the same as that of the coil spring 10.
The strength is set to be able to withstand the jumping force of the rear portion 2b of the seat cushion 2 due to the biasing force of the portions a and 10b. Further, the rear part 2b of the seat cushion 2 is provided with cushioning rubbers 13a, 13b on both sides of the engagement piece 11, and a support bracket 14a, which is provided on the frame 5 side via the rubbers 13a, 13b.
14b, and a handle 15 is arranged on the side.

On the other hand, the slider 6 supporting the front part 2a of the seat cushion 2 has two roller shafts 16 at the front and rear.
a, 16b are fixed, and this roller shaft 16a,
Roller 1 rotatably provided at both ends of 16b
7a, 17b and 18a, 18b are frame 5
The guide rails 19a and 19b are disposed parallel to each other in the front-rear direction on the left and right sides of the guide rails 19a and 19b, and are slidable in the front-rear direction along the guide rails 19a and 19b. One ends of links 20a and 20b are engaged with the left and right sides of the rear roller shaft 16b to assist the balance when the slider 6 slides, and the other ends of the links 20a and 20b are pivotally supported at the bottom of the frame 5. It is pivotally connected to a rod 21, and is configured to swing around the rod 21 as the slider 6 slides back and forth. Further, lugs 22a and 22b are protruded from the left and right sides of the center of the slider 6, and a lever rod 23 is inserted into these lugs 22a and 22b through the bracket 8a. is fixed. The engaging pieces 24, 25 have front engaging parts 24a, 25a and rear engaging parts 24b, 25b, respectively, and are rotatable by lever rods 23. A stopper is provided on the frame 5 side correspondingly. That is, a front stopper 26 is arranged at a position corresponding to the front engaging parts 24a, 25a, and a support bracket 14a is arranged at a position corresponding to the rear engaging parts 24b, 25b when the slider 6, which will be described later, is slid backward. , 14b
A rear stopper 27 is fixed to the rear stopper 27, and the front engaging portions 24a and 25a are engaged with the front stopper 26 in a normal state.

Next, the operation of the seat according to this example configured as above will be explained.

First, hold the handle 15 and press the seat cushion 2.
When the rear part 2b of the seat cushion 2 is lifted upward and the engagement between the engagement piece 11 and the catch spring 12 is released, the rear part 2b of the seat cushion 2 is rotated about the pivot 9 by the biasing force of the coil springs 10a and 10b. jumps up into an upright state, and the surface portion of the seat cushion 2 is located on the front side.

(Illustrated with a dashed line in FIG. 1) After that, with the rear part 2b of the seat cushion 2 in an upright position, the lever rod 23 is operated in the direction of arrow a as shown in FIG. The engagement between the engagement parts 24a and 25a and the front stopper 26 is released, and the guide rail 19 of the slider 6 is released.
Seat cushion 2 by sliding along a and 19b.
When it moves backward and reaches the rear end, the engaging piece 2
4 and 25, the rear engaging portions 24b and 25b engage with the rear stopper 27, and the rear portion 2b of the seat cushion 2 is fixed in an upright state.

(Illustrated with two-dot chain lines in Figure 1) When returning the seat cushion 2 to its normal state, operate the lever rod 23 in the direction of arrow b to connect the rear engaging portions 24b, 25b of the engaging pieces 24, 25. Release the engagement with the rear stopper 27 and move the slider 6.
After moving the seat cushion 2 forward and engaging the front engaging parts 24a, 25a of the engaging pieces 24, 25 with the front stopper 26, the rear part 2b of the seat cushion 2 is moved forward by the coil springs 10a, 10.
It is tilted against the biasing force b, and the engaging piece 11 is engaged and fixed to the catcher spring 12.

Incidentally, the above-mentioned tilting operations such as raising and tilting the seat cushion 2 and operations for moving the seat cushion 2 back and forth using the slider 6 are performed by grasping the handle 15 arranged on the side surface of the seat cushion 2.

As described above, in this example, the rear part 2b of the seat cushion 2 is raised up, and the seat cushion 2 is moved rearward and fixed by the slider 6 in the erected state, so that the back surface of the seat cushion 2 is exposed. It does not spoil the appearance.

It should be noted that the configuration according to this example does not specify the present invention, and it goes without saying that various configurations are possible depending on the situation of the automobile without departing from the gist of the present invention.

As described above, according to the present invention, in a passenger seat for an automobile, the rear part of the seat cushion is raised up, and while the rear part of the seat cushion is raised, it is moved rearward and locked. , the driver's visibility through the small window for visibility when making curves is sufficient, improving safety, and the back side of the seat cushion is not exposed compared to conventional front flip-up seat cushions. This allows us to provide seats with high appearance quality in a simple configuration.
In addition, since there is no need to move the seat back, it is easy to operate and can be used conveniently even in a narrow vehicle interior, making it particularly effective when applied to the passenger seat of a truck.
