Abstract
Abstract The multiple seat unit of a rocking or reclining type chair employs linkage mechanism therefor and for the leg rest which is similar to that used in a single unit chair construction. Some modification is required to the unit and mechanisms when two or more seating areas are provided for supporting the mechanisms between the side and center member of the unit. The end seating areas of a unit have tilting backs, movable seats and adjustable leg rests which operate independently of each other. The rocking type of multiple seating unit is a single construction which may be retained from rocking by locking it in tilted position at each side of the unit. The rocking unit will have a seating capacity for two or more occupants while the reclining unit for a plurality of occupants has only the end units which are reclinable and provided with leg rests, the seating portion therebetween has a rigid back and seat without leg rests.
