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 converted to face rearward.

In a seat structure where the driver's seat and front passenger's seat face rearward and face the rear seat, if the driver is to drive with the front passenger's seat facing rearward, the driver will have to worry about the backrest of the front passenger seat and the passenger. As a result, there is a problem in that side visibility is greatly restricted and safe driving is not possible.

The present invention has been made to solve such problems, and is provided with actuating members that operate according to the switching state on each of the driver's seat and the passenger's seat, and a rotary operation lever provided on each of the other seats. It can be operated by remote control from the actuating member, and the rearward rotation of the passenger seat is based on the backward rotation of the driver's seat, and the forward rotation of the driver's seat is made on the premise that the front passenger seat is rotated. It is designed to regulate operating procedures.

Next, details of the present invention will be explained with reference to embodiments shown in the drawings. This embodiment is, for example,
As shown in Japanese Patent No. 31453, the seat cushion is made to float during rotation, and this floating operation is used to determine the rotation operation procedure.

A seat cushion 1 for a driver's seat is placed on a base part 2 of a vehicle body, and is configured to be lifted from the base part 2 when rotated rearward.

An operating lever 5 is rotatably supported on a pin 4 provided on the base portion 2. The actuation lever 5 has two arm parts 5a and 5b, and has a base part 2.
A spring 7 is stretched between the pin 4 and the pin 4 so that the pin 4 is biased to rotate in the F direction.

As shown in FIG. 1, when the seat cushion 1 is placed facing forward and not floating, one arm 5a of the actuating lever 5 fits into the through hole 1b provided in the bottom plate 1a of the seat cushion 1. It's becoming like that.

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 resists the biasing force of the spring 7 and the bottom plate 1a of the seat cushion 1 press against. (In this case, this is because there is no through hole provided in the portion of the bottom plate 1a that the arm portion 5a contacts.) That is, the operating lever 5 comes to rotate in the opposite direction to F.

Further, an operating lever 10 for rotating the seat cushion 1 is rotatably supported on a pin 9 provided on the base portion 2. Further, an engagement pin 14 is fitted into a sleeve 12 provided on the base portion 2. The engagement pin 14 is located on the side of the operating lever 10, and when projected from the sleeve 12, engages with the operating lever 10, making it inoperable.

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.

An operating lever 25 is rotatably supported on a pin 24 provided on the base portion 22. The actuating lever 25 has two arm parts 25a and 25b, and a spring 27 is stretched between the arm part 25a and the base part 22, so that the actuating lever 25 is biased to rotate in the G direction around the pin 24. There is.

As shown in FIG. 5, when the actuating lever 5 rotates the seat cushion 21 backwards and sets it in place without floating, one arm 25a of the actuating lever 5 fits into the through hole 21b provided in the bottom plate 21a of the seat cushion 21. It's starting to fit in.

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. do. That is, the operating lever 25 comes to rotate in the direction opposite to G.

In addition, the pin 29 provided on the base portion 22 has
Operation lever 30 that rotates the seat cushion 21
is rotatably supported. Furthermore, the base portion 22
An engaging pin 34 is fitted into a sleeve 32 provided in the sleeve 32. 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 remote control wire 41 connects 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.
and the arm 25 of the operating lever 25 on the passenger seat side.
b and the engagement pin 14 on the driver's seat side are connected by a remote control wire 42.

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

In Figure 1, seat cushion 1 of the driver's seat
The seat cushion 21 on the passenger seat also faces forward and is fixed without floating. The arm portion 5a of the operating lever 5 is fitted into the through hole 1b, and the operating lever 5 is rotated in the F direction by the bias of the spring 7, so the remote control wire 41 moves in the H direction. However, since this causes the engagement pin 34 to protrude, the operation lever 30 on the passenger seat cannot be rotated. Therefore, the passenger seat cannot be rotated backwards.

On the other hand, due to the bottom plate 21a of the passenger seat seat cushion 21, which is placed facing forward without floating,
The arm portion 25a of the operating lever 25 is pressed against the bias of the spring 27. In other words, the operating lever 25 is G
The remote control wire 42 moves in the K direction and pulls down the engagement pin 14. Therefore, the operating lever 10 is in a state where it can be rotated.

FIG. 2 shows the operation lever 10 in the state shown in FIG.
The figure shows the state in the process of lifting the seat cushion 1 and rotating it backwards by operating the seat cushion 1.

FIG. 3 shows a state in which the seat cushion 1 is rotated backwards and fixed without floating. Since the operating lever 5 is in pressure contact with the bottom plate 1a of the seat cushion 1, the remote control wire 41 is moved in the direction opposite to H. move and pull down the engagement pin 34. Therefore, the operating lever 30 is in a state where it can be rotated.

FIG. 4 shows the operating lever 30 in the state shown in FIG. 3.
The figure shows the process of lifting the seat cushion 21 and rotating it backwards. During this process, the actuating lever 25 is released from the pressure applied by the bottom plate 21a, so the operating lever 10 for the driver's seat is rendered unrotatable by the engagement pin 14, and the seat cushion 1 remains rotated rearward. It's becoming like that.

FIG. 5 shows a state in which the seat cushions 1 and 21 are both rotated backwards and placed in place, and since the operating lever 25 is fitted into the through hole 21b of the seat cushion 21, the operating lever 10 is not engaged. pin 1
4 makes it unrotatable, and on the other hand, the operating lever 5 is pressed by the bottom plate 1a of the seat cushion 1, so the engaging pin 34 is pulled down and the operating lever 30 becomes rotatable. ing.

In this way, in this embodiment, the seat cushion is floated and rotated.
It is also possible to apply the present invention to a vehicle in which the seat is rotated without lifting the seat cushion, or a vehicle in which the seat faces rearward by reversing the seat backrest.

The present invention is for converting the driver's seat and the front passenger's seat to face backwards. Since the present invention is configured as described above, the steps shown in FIGS. To return the seat to a forward-facing position,
We will take the opposite procedure. 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.
