Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle seat structure in which a driver's seat and a passenger seat located parallel to the driver's seat can be turned to face rearward.

In a seat structure where the driver's seat and front passenger's seat face rearward and face each other, if the passenger seat is left facing rearward while driving, the driver will be forced to The problem is that side visibility is severely restricted, making it impossible to drive safely.

The present invention is designed to solve this problem, particularly in the driver's seat and passenger seat.

An operating member is provided in the seat that operates according to the switching state, and the rotation control lever provided on each other seat can be operated by remote control from the operating member, and the rearward rotation of the passenger seat is controlled by the driver's seat. The rotation operation procedure is regulated on the assumption that the driver's seat is rotated backwards, and that the front passenger seat is rotated forward.

Next, details of the present invention will be explained with reference to embodiments shown in the drawings. In this embodiment, as shown in, for example, Japanese Utility Model Publication No. 51-31453, the seat cushion is floated during rotation, and this floating operation is used to determine the rotation operation procedure.

The driver's seat 7-cushion J is placed on the base portion 2 of the vehicle body, and is configured to be lifted from the key seat portion 2 when rotated rearward.

An operating lever 5 is rotatably supported on a pin 4 provided on the base portion 2. Operating lever 5 12 arms 5
a and 5b, and a spring 7 is passed between the base portion 2 and the pin 4 to rotate in the F direction.

As shown in FIG. 1, the actuating lever 5 is configured such that when the seat cushion 1 is placed facing forward without floating, one arm portion 5a fits into the through hole 1b provided in the bottom plate 1a of the seat cushion 1. It has become.

As shown in FIGS. 3 to 5, when the seat cushion 1 is rotated backward and placed in place without floating, the arm portion 5a is pressed against the bottom plate 1a of the seat cushion 1 against the bias of the spring 7. do. (In this case, the bottom plate 1 that the arm 5a touches)
This is because there is no through hole in part a. )
In other words, the operating lever 5 rotates in the direction opposite to F.

In addition, a control lever 10 for rotating the seat cushion 1 is rotatably supported at a shaft 79 provided on the base portion 2, and a sleeve 12 provided on the base portion 2 is connected thereto. The matching pin 14 is fitted. The engagement ring J4 is located on the side of the operating lever 10, and when protruded from the sleeve 12, it engages with the operating lever 10 and prevents it from being operated.

Similarly, the seat cushion 21 of the passenger seat is placed on a base portion 22 of the vehicle body, and is configured to be lifted from the base portion 22 when rotated rearward.

A pin 24 provided on the base portion 22 has an operating lever 2
5 is a pivot support that can be rotated freely. The actuating lever 25 has two arm parts 25a and 25t), a spring 27 is passed between it and the base part 22, and a G force is applied around the pin 24.
It is designed to be biased to rotate in the direction.

As shown in FIG. 5, the actuating lever 5 is used when the seat cushion 21 is rotated rearward and placed in place without floating.
One arm portion 25a is the bottom plate 21 of the seat cushion 21.
It is designed to fit into the through hole 2] 1) provided in a.

As shown in FIGS. 1 and 3, when the seat cushion 21 is placed facing forward without floating, the arm portion 25a is pressed against the bottom plate 21a of the seat cushion 21 against the bias of the spring 27. Pressure contact. That is, the operating lever 25 comes to rotate in the direction opposite to G.

Further, an operating lever 30 for rotating the seat cushion 21 is rotatably supported on a pin 29 provided on the base portion 22. Further, a retaining pin is fitted into a sleeve 32 provided on the base portion 22. The engagement pin 34 is located on the side of the operating lever 30, and when projected from the sleeve 32, engages with the operating lever 30, making it inoperable.

In this way, the operating levers and engagement pins provided on the driver's seat side and the passenger seat side are connected by a remote control wire.

That is, the arm portion 5b of the operating lever 5 on the driver's seat side and the engagement pin 34 on the passenger seat side are connected by a remote control wire 41, and the arm portion 25b of the operating lever 5 on the passenger seat side and the retaining pin on the driver's seat side are connected. 14 by a remote control wire 42.

1 to 5 show the procedure for sequentially rotating the driver's seat and passenger seat backwards.

In FIG. 1, both the driver's seat seat cushion 1 and the passenger seat seat cushion 21 face forward and are stationary without floating. The arm portion 5a of the actuating lever 5 is fitted into the through hole 1.1) K, and the actuating lever 5 is rotated in the F direction by the force of the spring 7. direction, thereby causing the engagement pin 34 to protrude, making it impossible to rotate the operation lever 30 on the passenger seat.

Therefore, the passenger seat cannot be rotated backwards.

On the other hand, the arm portion 25a of the operating lever 25 is pressed against the bias of the spring 27 by the bottom plate 2],a of the seat cushion 21 of the passenger seat, which is not lifted but is placed facing forward. That is, the operating lever 25 is rotated in the opposite direction to the direction G, and the remote control wire 42 is moved in the direction L, pulling down the engagement pin 14. Therefore, the operating lever]0 is in a state where it can be rotated.

FIG. 2 shows a state in which the operating lever 10 is moved, the seat cushion 1 is raised, and the seat cushion 1 is rotated rearward, compared to the state shown in FIG.

FIG. 3 shows a state in which the seat cushion 1 is rotated backwards and placed in place without floating. Since the operating lever 5 is in pressure contact with the bottom plate [a] of the seat cushion 1, the remote control wire 4
1 moves in the opposite direction to H and pulls down the locking pin 34. Therefore, the operating lever 30 is in a state where it can be rotated.

FIG. 4 shows a state in which the operating lever 30 is operated, the seat cushion 21 is raised, and the seat cushion 21 is rotated backwards in contrast to the state shown in FIG. 3. During this process, the actuating lever 25 is released from pressure by the bottom plate 21a, so the operating lever 10 on the driver's seat is rendered unrotatable by the engagement pin 14, and the seat cushion 1 remains rotated backwards. It looks like this.

Figure 5 shows the seat cushions 1 and 21 both rotated backwards and placed in place, and the operating lever 5 is fitted into the through hole 21b of the seat cushion 2, so it can be operated. is not rotatable by the engagement pin] 4, and on the other hand, since the operating lever 5 is pressed by the bottom plate 1a of the compression 1, the retaining pin 34 is pulled down and the operating lever 3O can be rotated. is in a state of

In addition, in this embodiment, the seat cushion is raised and rotated, but it is possible to rotate the seat without raising the seat cushion, or to rotate the seat by reversing the seat/cook rest. It is also possible to apply the present invention to a device that faces backward.

The present invention is for converting the driver's seat and the passenger's seat to face backwards, and since it is configured as described above, the steps shown in FIGS. 1 to 5 are followed, and furthermore, both To return the degree to a positive state, take the opposite steps. In other words, since the passenger seat is rotated backwards, the driver's seat must be rotated backwards before the passenger seat is rotated backwards, which has the advantage of preventing the vehicle from driving with the passenger seat facing backwards and ensuring safe driving. be.

[Brief explanation of the drawing]
