Abstract: A vehicle seat assembly has a hidden storage compartment disposed in a seat member of the seat assembly. The seat member is pivotally connected to a support mounted on a vehicle floor and is pivotable between forward and rear positions. The seat member has a seating side which faces upward in the rear position and an oppositely facing storage side which faces upward in the forward position. The storage side includes a recess in the seat member internally defining a storage compartment and has an openable cover normally closing the storage compartment and openable to allow access thereto. The cover forms a storage floor surface when the seat member is in the forward position. The assembly has a releasable latch for retaining the cover in a closed position and preventing spilling of the contents therefrom when the seat member is inverted in the rear position. When the seating member is in the rear position, the storage compartment is hidden from view.
