Definitions

• the invention is directed at storage systems, particularly load floor systems, for transportation vehicles, and, more particularly, to the covering of storage compartments in vehicles which may sometimes store fold-down or "stowable" seat assemblies.
• a number of vehicles have folding or removable seats in second and third rows to provide some of the advantages desired.
• the purpose of such seats is to adapt the automobile to multiple functions, such as carrying passengers and carrying cargo.
• the use of folding or removable seats has a number of advantages and disadvantages.
• a folding seat can require minimal actions on the part of the user, but afford only partial use of available vehicle volume for cargo.
• the cargo volume may also be uneven, providing a load floor having an irregular surface.
• a removable seat maximizes the availability of cargo volume, but requires much greater effort on the part of the user to physically remove the seat, and requires that the removed seat be stored outside the vehicle. The seat may thus not be readily available for conversion back to a passenger-carrying configuration.
• one or more rows of rear seat assemblies include a seat cushion and a seat back coupled to the seat cushion. Both the seat cushion and seat back may be pivoted forwardly providing more cargo volume in the vehicle.
• the seat cushion is pivotally coupled to the floor of the vehicle for movement between a generally horizontal seating position and a forwardly folded and upright position.
• the seat back is commonly pivotable between a generally upright seating position and a forwardly folded flat position adjacent the upright seat cushion.
• Fold flat means to have the seat cushion moveable between the seating position and a stowed position lying adjacent the floor of the vehicle and to have the seat back moveable between the upright seating position and a forwardly folded flat position overlying the seat cushion in the stowed position.
• Multiple or complex latching mechanisms are typically used for releasably locking the seat cushion and seat back in the respective seating positions.
• the seat assembly takes up storage space (cargo volume) in the vehicle and provides an uneven floor surface.
• United States Patent No. 6,705,658, entitled “Collapsible Vehicle Seat Assemblies” and assigned to Lear Corporation is directed at a collapsible vehicle seat assembly pivotable from an upright position into a collapsed position within a stowage cavity in the vehicle floor and a sliding cover operative as a vehicle load floor covering the folded seat.
• This design includes a pivot point above the load floor and thus does not allow for a flat load floor when the seats are folded down.
• a load floor system that allows seats to be out of the way so as to increase cargo space without the attendant complexity and awkwardness associated with the manual removal of heavy, bulky seats.
• a load floor system which may be readily incorporated into the existing floor of a motor vehicle and which covers recesses, tubs and potential storage compartments formed in the floor pan of a vehicle when the second and third rows of seats are upright, and which further allows the seats to be folded down and stored in the recesses to provide a relatively smooth durable load bearing surface over the folded seat.
• a load floor system which it is of improved construction and which preferably has hinged doors which allow second and third row seats in a vehicle to be pivoted and folded into a depression in the floor pan of the vehicle such that the hinged doors may overlie the folded seat and provide increased cargo space having a load bearing flat surface.
• It is a further object of the present invention to provide a load floor system comprising a space frame reinforced with metal brackets and wherein the doors are formed of a low density reinforced (RRIM) or structural reaction injection molded material (SRIM).
• RRIM low density reinforced
• SRIM structural reaction injection molded material
• the present invention is directed to a storage system for covering a recess in a vehicle, the system comprising a frame forming at least a portion of the periphery of the recess, one or more doors each of which includes one or more edges.
• the one or more doors are hingedly connected to the frame, wherein the doors are pivotable between a first position closing out the frame to cover the recess and a second position allowing access within the frame to the recess when the door is pivoted away from said frame.
• the system is capable of storing an article wherein the one or more doors comprise one or more panels hinged together.
• the present invention is directed at a closure for closing out a recessed compartment in a vehicle, the compartment capable of storing at least one article, the closure comprising one or more doors each of which includes one or more edges.
• the one or more doors are hingedly connected to the compartment along one or more edges, the doors pivotable between a first position closing out the compartment and covering the compartment, and a second position allowing access within the compartment when the door is pivoted away from the compartment.
• the one or more doors may further comprise two or more panels hinged together and may be capable of folding upon themselves to provide access to the compartment.
• the present invention is directed to a load floor system particularly for transportation vehicles which comprises a space frame including one or more hinged doors which overlies a recessed area or stowage compartment in a vehicle floor such that adjacent seats may be pivoted or folded down into the recessed area and the hinged doors lowered to provide a flat cargo area for the vehicle. Further, when the sets are in an upright or use condition, the doors overlie the recessed area providing an enclosed stowage area having load bearing properties.
• the load floor system may be further adapted to integrate the storage area or tub into the assembly, to provide both aesthetic and functional features to delight the occupants or even to be used in a vertical configuration on the sidewalls of a vehicle.

• Friction hinges of this type provide an anti-slam feature which eliminates pinch points by allowing the hinged door 70 to be placed at any attitude or position and allow the door 70 to remain in that position, either for access to the compartment 30 or for folding the seat 20, into the compartment 30. Once access is complete, the door 70 may be lowered into its horizontal position overlying the compartment 30. To allow room for the seat 20, to be folded into the compartment 30, the door 70 preferably also includes a second panel 74 which is attached along one edge to the first panel 72 by a piano or like hinge 64 (see FIG. 3A). This shortens the movement arm of the door 70 requiring less friction or torque to hold the door open and provides a shorter door which allows easier access to the compartment 30.

• FIG. 8 A second embodiment of the load floor system 1OA is shown in FIG. 8 wherein the tub, enclosure or compartment 3OA is attached to or preferably integrally molded with the space frame outer 14. This provides a modular assembly that may be easily installed in a vehicle and eliminate the mating to different vehicle surfaces, reducing tolerance problems and reducing gaps and uneven appearance.
• the floor of the vehicle may be of a somewhat different shape, and for conversion purposes to a "utility van" the seats and modular floor assembly may readily be removed.
• the construction of this second embodiment system 1OA is preferably quite similar to the first embodiment of the present invention in that the upper portion includes a space frame 12A extending around at least a portion of the system 1OA, the space frame preferably comprising a plastic outer molding 14A and one or more doors 7OA hinged to the space frame 12A.
• the doors 7OA preferably comprise a series of hinged panels 72 A, 74A, 76A for allowing access to or stowing foldable seats in compartment 3OA.
• Bracketry may be attached to or insert-molded into the space frame 12A when it is manufactured to provide support for the doors as well as load bearing capability and hinge attachment along the edges. While the compartment 3OA may be separately molded and attached to the space frame 12 A prior to assembly into the vehicle, it is preferred that the space frame 12 A and enclosure 3OA be molded as a single unit. Subsequently, the hinged doors 70, latches 9OA and hinges 62A, 64A, 66A along with door seals, bumpers, etc. may be attached.
• the molding comprise a thermoplastic or thermoset material for best strength to weight properties.
• Processes including, but not limited to, injection molding, blow molding, rotational molding, and hand-lay-up may be used, but preferably a reaction injection molding process (RIM) may be used to provide a thin-walled product of reduced density and high strength.
• RIM reaction injection molding process
• Either SRIM or RRIM formulations by including fillers and reinforcements may provide the high strength and low weight desired.
• the module, including the frame 12A and compartment 3OA may be formed in a single molding step and the metal reinforcement may be insert-molded in place. Further, either of the frame 12A and compartment 3OA may first be molded and then attached by molding the other of the frame or compartment against the first molding.
• either or both of the space frame 12 or compartment 3OA may be molded of glass fiber reinforced thermoplastic.
• the enclosure or compartment 30, 3OA whether a part of the vehicle floor or molded as an integral part of the load floor system 1OA, may include a variety of features to surprise and delight the vehicle owner.
• the 7OA may be decorated with carpet or other attractive and easy to clean materials.
• the doors may include hooks to hang grocery bags on when the doors are open.
• the compartment may include hooks, cargo nets, and reconfigurable panels or containers to assist in organizing that space.
• the compartment may be designated and tailored to store a spare tire, a laptop computer, electronic equipment and the like. Further, it may contain electronic features, such as a docking station, lighting, outlets, speakers or even be conditioned to store food and beverages.
• the doors 70, 7OA and compartment 30, 3OA of the present invention may further comprise sound reducing materials.
• sound reducing materials is therefore defined as any material which might absorb, attenuate, insulate or serve as a barrier to sound. This may include, but is not limited to, the inclusion of layers of foam, highly filled thermoplastics such as massback, and fibrous materials such as Maratex®, shoddy, polyester fibers, nylon fibers, bicomponent fibers and combinations thereof applied to the doors and/or tub. It is further contemplated that load floor systems 10, 1OA may find use in pickup trucks and the like to provide a decorative, secure storage compartment in the pickup bed, wherein the upper surface (doors, space frame) may function as a load floor.
• the present invention may be used in a vertical configuration to provide storage along the side walls of a SUV, minivan, truck, bus or other transportation vehicle. This provides an attractive, modular, secure storage capability which may be easily installed and accessed.
• door construction as described herein namely RRIM, long glass fiber reinforced thermoplastic or a thermoplastic molding attached to a steel stamping, may be used as a lid or cover for any compartment within the interior of a transportation vehicle and hingedly attached to a frame portion thereof.
