Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driver's seat in a one-box type vehicle in which a person with a lower limb disability can get into a vehicle in a wheelchair, move to a driver's seat and drive himself.

[0002]

2. Description of the Related Art A one-box type vehicle which can be equipped with a lift mechanism requiring a considerable space is suitable for a vehicle in which a disabled person gets in a wheelchair. Specifically, the driver once gets into the space behind the driver's seat and the passenger's seat from the rear gate opening or the side door opening, and then transfers to the driver's seat.

[0003]

At this time, in order to move from the wheelchair to the driver's seat, it is necessary to lay the wheelchair next to the driver's seat. Generally, the driver's seat is provided with a slide mechanism for sliding the seat back and forth, but the amount of slide is usually limited to about 200 mm. Therefore, even if the passenger seat is equipped with a slide mechanism, even if it is fully slid to the front end position, the gap between the driver's seat and the passenger seat is very small, and the wheelchair is placed behind the passenger seat. However, it cannot be laid on the driver's seat.

For this reason, it is conceivable that the passenger seat is inevitably removed and the wheelchair is laid sideways on the driver's seat. However, in this case, even if there is a passenger, the passenger is assisted from the passenger seat while traveling. Can not do.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned problems, and has as its object to provide a vehicle driver's seat apparatus capable of easily moving from a wheelchair while securing a passenger seat next to the driver's seat. Aim.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention has a normal driving position and a transfer position in which a wheelchair accommodated in a rear room of the vehicle behind the normal driving position can be transferred to a driver seat so as to be changeable. A seat moving means for moving the driver's seat between a normal driving position and a transfer position by a motor drive is provided. By moving the driver's seat to the transfer position by the seat moving means, the wheelchair can be laid sideways on the driver's seat, so that the driver can easily change in the passenger compartment.

In particular, the seat moving means is constituted by a long slide mechanism which allows a seat unit including a seat cushion and a seat back to slide back and forth, and the long slide mechanism includes a fixed rail extending parallel to the front and rear direction. A base frame, and a slide frame unit that supports the seat unit and slides along the fixed rail. The base frame is provided with a ball screw disposed parallel to the fixed rail and a motor that drives the ball screw to rotate. Since the slide frame unit is provided with a ball nut that engages with a ball screw, the driver's seat performs stable straight-line movement.

[0008] In particular, when the slide frame unit is at the rear end of the fixed rail, the above-mentioned transfer position is defined as the above-mentioned transfer position, and the height of the fixed surface of the wheelchair seated laterally with the seat surface of the seat cushion at the transfer position is changed. Preferably, it is inclined upward and backward so as to match. Since the height of the seat surface of the seat cushion matches the height of the seat surface of the wheelchair at the transfer position, the transfer between the seats is particularly easy.

A lock means for fixing the slide frame unit at the driving position and the transfer position can be provided between the slide frame unit and the base frame. This ensures that the driver's seat is held in position during driving or during a transfer.

[0010] Similarly, by providing shock absorbing means operating immediately before each of the driving position and the transfer position between the slide frame unit and the base frame, the shock at the time of stopping at each position is reduced. Further, the seat unit can be supported by the slide frame unit via a normal adjustment slide mechanism having a slide distance shorter than the slide distance of the long slide mechanism, thereby enabling fine adjustment of the seat position at the driving position. it can.
