  • Patent number: 4189876
    Abstract: Seating for a telescoping row system or the like includes a chair back and seat mounted to a frame which automatically raises and lowers as the rows are opened and closed respectively. A pair of hinge mechanisms are clamped to the frame at the side of each chair for mounting the seats and backs while permitting them to rotate about a common axis which extends along the intersection of the hip and lumbar region of the occupant. The hinge mechanisms include one spring which normally biases the seat of the chair to the three-quarters fold position when it is unoccupied, but permits it to be lowered for an occupant or moved to the fully raised position for passing. In one embodiment, a second spring biases the back of each chair to the use position when the chair is raised. When the chair is folded for storage, the back and seat are rotated toward each other to a fully closed position.
