This invention relates to vehicles, such as vans, mini-vans and sport utility vehicles, having a multi-use compartment that can be alternately configured for seating of passengers or carrying cargo, and more particularly to passenger seating that can be optionally stowed on-board such vehicles, for providing expanded cargo carrying capacity.
In vehicles such as vans, mini-vans and sport utility vehicles, it is desirable that passenger seating arrangements be optionally stowable on-board the vehicle, in a manner that provides a large, unimpeded volume for carrying cargo. It is also desirable that the stowable passenger seating arrangements have cushions that support passengers at a height above the floor that is approximately at the same level as the driver and any front seat passengers, so that the passengers seated on the stowable seats can enjoy the view through vehicle windows and enter and exit the stowable seats, when the stowable seats are deployed, without having to step up out of a seating well in the floor. It is especially desirable that the floor of the cargo area be flat when the seating is stowed, to facilitate loading and carrying large sized cargo, such as sheets of plywood, large cartons, or bulky items such as bicycles or other recreation equipment.
U.S. Pat. No. 6,416,107 B1, to Kanaguchi, et al., discloses a forward facing bench-type seat mounted as the rearmost-row seat on a raised portion of a floor surface extending rearwardly from the rearmost-row seat, toward the rear of a vehicle. A seat receiving recess is formed in and extends downwardly from the raised floor surface extending rearwardly from the rearmost-row seat. The rearmost row seat can be folded in such a manner that a seat back thereof is brought down forwardly to be laid on a seat cushion thereof, and the folded seat can be turned rearwardly about rotation shafts to be received in the seat-receiving recess. The raised floor surface, in which the seat receiving recess is formed, is disposed at a level higher than a foot-resting floor seat for the rearmost-row seat. The rotation shafts on the seat cushion of the rearmost-row seat are disposed at a level that is lower than the floor surface, in which the seat-receiving recess is formed and also is lower than an upper side of the receiving recess.
The approach to providing stowable seating disclosed in Kanaguchi is less than desirable, because the seat must be mounted on a raised floor surface. The raised floor surface consumes space inside the vehicle that could be used for carrying cargo, and results in a floor surface that is stepped up at the rear, rather than being totally flat.
What is needed, is a new approach to providing passenger seating that can optionally be stowed on-board the vehicle in a manner providing the desired features and functionality described above.
Our invention provides a stowable, folding seating apparatus, for a vehicle having a floor defining a floor surface that may be entirely flat when the seating apparatus is stowed. The seating apparatus includes a stowable seat having a seat cushion supported on one or more legs above the floor, and a seat receiving recess in the floor for on-board stowage of the seat. The seat may also include a seat back that is foldable upon the seat cushion for stowage of the seat in the seat receiving recess.
In one form of our invention, the stowable seating apparatus includes a seat receiving recess in the floor, extending downward from the floor surface and opening upward through the floor surface, and a seat having a seat cushion and a leg operatively attaching the seat cushion to the floor for selective movement of the seat with respect to the seat receiving recess between a deployed position of the seat and a stowed position of the seat in the seat receiving recess.
The seat cushion has an upper surface for receiving the buttocks of a passenger when the seat is in the deployed position, and a lower surface facing the floor surface when the seat is in the deployed position. The seat cushion is inverted when the seat is in the stowed position with the upper surface of the seat cushion facing downward in the seat receiving recess and the lower surface of the seat cushion facing upward in the seat receiving recess.
The leg includes an upper pivot operatively attached to the lower surface of the seat cushion and a lower pivot operatively attached to the floor, for selective pivoting movement of the seat between the deployed and the stowed positions of the seat, by pivoting the seat cushion about the upper pivot, and pivoting the leg about the lower pivot between a substantially vertical deployed position of the leg and a substantially horizontal stowed position of the leg, with the leg in the substantially horizontal stowed position extending into the seat receiving recess in a direction substantially parallel to the floor surface.
In another form of our invention, the seat receiving recess extends downward from the floor surface and opens upward through the floor surface. The seat has a seat cushion, a foldable seat back, and a leg operatively attaching the seat cushion to the floor for selective movement of the seat, with respect to the seat receiving recess, between a deployed position of the seat, an intermediate position of the seat, and a stowed position of the seat.
The seat cushion includes an upper surface for receiving the buttocks of a passenger when the seat is in the deployed position, and a lower surface facing the floor surface when the seat is in the deployed position. The foldable seat back is pivotably attached to the seat cushion to be foldable upon the upper surface of the seat cushion to a folded position of the seat back, and openable to an open position of the seat back for supporting the back of a passenger seated upon the cushion.
The leg has an upper pivot operatively attached to the lower surface of the seat cushion and a lower pivot operatively attached to the floor for selective movement of the leg between a substantially vertical deployed position of the leg, for supporting the seat cushion in the deployed position of the seat whereat the seat cushion extends substantially perpendicular to the leg, and a substantially horizontal stowed position of the leg whereat the leg extends into the recess in a direction substantially parallel to the floor surface.
The seat cushion is operatively attached to the upper pivot of the leg for selective movement with respect to both the seat receiving recess and the leg, between the deployed position of the seat, whereat the seat cushion extends substantially perpendicular to the leg with the leg in the deployed position of the leg and the seat back is in either the open or the folded position, and the intermediate position of the seat whereat the seat cushion with the seat back folded thereupon extends substantially perpendicularly to the leg with the leg in the stowed position of the leg.
The seat cushion with the seat back folded thereupon is foldable from the intermediate position of the seat to the stowed position of the seat within the seat receiving recess, by pivoting the seat cushion with the seat back folded thereupon about the upper pivot of the leg and into the seat receiving recess.
In some forms of our invention, the seat does not extend above the floor surface when stowed in the seat receiving recess in the floor. The seating apparatus may include a cover for closing the seat receiving recess, with the cover having an upper surface thereof extending substantially parallel to the floor surface when the cover is closing the seat receiving recess.
A seating apparatus, according to our invention, may include a passenger seat in which the seat cushion, seat back and leg are foldable in a forward direction in the vehicle, for stowage in a seat receiving recess located forward of the deployed position of the seat. In alternate forms of our invention, the seat cushion, seat back and leg are foldable in a rearward direction in the vehicle, for stowage in a seat receiving recess located rearward of the deployed position of the seat. In yet other forms of our invention, the seat cushion, seat back and leg are foldable in a transverse direction in the vehicle, for stowage in a seat receiving recess located beside the deployed position of the seat.
Our invention may also take the form of a method for operating a seating apparatus according to our invention, as described above or in the subsequent detailed description.
The foregoing and other features and advantages of our invention will become further apparent from the following detailed description of exemplary embodiments, read in conjunction with the accompanying drawings.
