Abstract: Some embodiments are directed to an indicator assembly for indicating an orientation between a vehicle seat back and a seat bottom. The indicator assembly can include an outer plate assembly that is configured to be supported by the seat bottom, and a movable plate that is movably supported by the outer plate assembly. A biasing device can apply a biasing force to bias the movable plate toward the seat back when the outer plate assembly is supported by the seat bottom to thereby define a projecting portion of the movable plate. The biasing device can enable the movable plate to move upon application of a force to the projecting portion that is greater than the biasing force. An indicator can indicate a relative orientation between the seat back and the seat bottom based on the amount of movement of the movable plate.
