A passenger vehicle is provided with a seating row oriented in a passenger compartment and adjacent to a storage compartment. The seating row has a seat back that is pivotally connected to a vehicle body. A battery is disposed within the storage compartment. A tray is provided with a forward end that is pivotally connected to the seat back, and a rearward end that is supported slidably on the vehicle body. The tray is movable in a fore-and-aft direction as the seat back pivots on the vehicle body between a collapsed position and an upright position. The tray is disposed over the seat back and the battery when the seat back is in the collapsed position for providing a raised platform that extends into the passenger compartment.
