Abstract

The disclosure is directed to an improved rear seat arrangement for use in a motor vehicle and the like in which a seat cushion and a corresponding seat back are simultaneously divided laterally into two portions, respectively capable of being altered in their positions independently of each other so as to meet such a demand as for further carrying persons in addition to loading of long length items, etc. on the motor vehicle.

Claims

1. A rear seat arrangement for use in a motor vehicle and the like which comprises a first seat and a second seat provided at a left side and a right side of the motor vehicle by dividing a sheet cushion member and a seat back member into corresponding two portions for said first and second seats, each of said first and second seats further comprising a seat cushion portion pivotally connected at its forward lower portion to a seat floor surface so as to be rotated for being erected at a forward position of said seat, about the pivotal connection at said forward, lower portion, and a seat back portion having a first pivot provided at its lower portion in a position higher than a surface of a load carrying platform at a rear portion of said seat, and pivotally connected to the seat floor surface so as to be rotatable for inclination in the forward direction through connecting members for guiding said first pivot to a position lower than the surface of said load carrying platform, the connecting members are each connected at a first end to the seat back portion and at a second end to the seat floor, respectively, the first end supporting the first pivot and the second end movably supported with respect to the seat floor, the connecting members permitting the first pivot to move from a position higher than the surface of the load carrying platform to a position lower than the surface of the load carrying platform, said divided first and second seats being respectively arranged to be independently changed over to an ordinary position wherein said cushion portion is held horizontal, with said seat back portion held in an erect state, so that the seat cushion portion and the seat back portion for one of said divided first and second seats may form the same continuous plane with respect to the sheet cushion portion and seat back portion for the other corresponding one of said first and second seats, and to a first folded position wherein the seat back portion is folded upon the upper surface of the seat cushion portion through rotation of said seat back portion about said first pivot for inclination thereof in the forward direction when said first pivot is located at a position higher than the surface of said load carrying platform, and also, to a second folded position wherein said seat cushion portion is erected through rotation thereof, about said pivotal connection, with said seat back portion being folded into a recess formed on the seat floor surface by the erection of said seat cushion portion, through rotation of said seat back portion by the movement of the connecting members, the first pivot is displaced to a position lower than the surface of said load carrying platform.

2. A rear seat arrangement as claimed in claim 1, wherein said connecting members are pivotally supported at the first end by the lower portion of said seat back portion through said first pivot, with said second end being pivotally supported by the seat floor surface through a second pivot, said first pivot being located in a position higher than the surface of the load carrying platform and said second pivot lower than the surface of the load carrying platform at ordinary positions of said rear seat arrangement, said connecting members being provided with a first restricting portion for restricting a rearwardly inclining angle of the seat back portion about the first pivot, and a second restricting portion for restricting the rotational angle about the second pivot.

3. A rear seat arrangement as claimed in claim 1, wherein a rear end of said seat cushion portion is held in contact with a lower end of said seat back portion in said ordinary position of said rear seat arrangement.

4. A rear seat arrangement as claimed in claim 3, wherein the forward lower portion of said seat cushion portion is hingedly connected to the seat floor surface through link arm members to provide said pivotal connection thereat.

5. A rear seat arrangement as claimed in claim 1, further including a locking means for locking said seat back portions to a vehicle body in said ordinary position of said rear seat arrangement.

6. A rear seat arrangement as claimed in claim 1, further including side cushion members fixed to a vehicle body in positions on ends of the seat back portions at the left and right sides and inner walls of a vehicle body.
