ABSTRACT:
A seating assembly, such as for use in auditorium seating, includes a pair of spaced frame assemblies and a seat and back, each of which is mounted between the frame assemblies. The seat assembly is mounted to the frame assemblies by means of an internal pivoting arrangement providing movement of the seat between an occupied position and an unoccupied, storage position in which the seat is substantially vertical. A biasing arrangement, such as a counterweight, moves the seat toward its storage position. The back is mounted between the frame assemblies by a pivoting back mounting arrangement, providing articulating movement of the back according to the position of the sitter's back. A biasing arrangement, such as a torsion spring, is associated with the back mounting arrangement for moving the back toward a storage position when the seat is unoccupied. The storage position of the back is substantially vertical, to provide a thin depth of approximately 13 inches to the seating assembly when the seat and back are both in their storage positions.
