DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a rear seat device for a van type vehicle.

In recent years, van-type vehicles have come to be used not only as commercial vehicles but also as camping cars. In order to use the vehicle as a camping car, conventional van-type vehicles have two rows of seats in the width direction of the vehicle in the rear cabin, and the seatbacks of each seat are folded back to create a bed. It is becoming possible to do this.

However, in conventional van-type vehicles like this, the tire house protrudes into the interior of the vehicle, and the seat in front of the tire house is usually long in the width direction of the vehicle to accommodate three people, so it is difficult to use the seat back. When I tried to make a bed by tilting it backwards, the seat back hit the tire house and became slanted, making it impossible to create a flat bed.

The present invention has been made in view of the above-mentioned conventional problems.A rear row seat is arranged between the left and right tire houses in the rear compartment of a van-type vehicle, and a wide seat is provided in front of the rear row seat. Front row seats consisting of a long main seat and a short sub-seat are arranged in a row in the vehicle width direction, and the sub-seats are foldable and erectable on the side of the main seat or the side wall of the vehicle body, and the main seats are arranged in a row in the vehicle width direction. By making the main seat freely movable between the reclining position and the reclining position in the center of the vehicle width by means of a moving means, and by making the seat back part of the main seat freely reclinable backwards to a horizontal position, the main seat is To provide a rear seat device for a van type vehicle which can be used as a bed by folding down to a horizontal position at the center of the width.
