Linkage operated recliner chair having a TV position wherein a footrest is projected forwardly by a control handle while the seat and backrest undergoes slight reclining movement relative to a fixed base. However, due to linkage connected between the footrest linkage and the seal linkage, the seat and backrest which is pivotally mounted to the seat, also undergo forward translatory motion during movement of the footrest to extended position. Thus, while the seat and backrest undergo rearward and downward reclining movement, the backrest will not engage an adjacent wall due to the translatory movement. Such action in the trade is known as wall avoiding. Further, and more pronounced, wall avoiding action is achieved by the chair of the present invention when moving to further reclining positions beyond the TV position. These positions are obtained by the occupant exerting back pressure on the backrest which, while causing the backrest to pivot in a rearward direction relative to the seat to increase the angle therebetween, also causes the actuation of two closed linkages to project the seat forwardly and consequently the backrest connected to it with compounded wall avoiding action. To return the chair to normal or upright position with the footrest retracted, the occupant removes back pressure from the backrest which causes the chair and seat to return to TV position after which the control handle is operated to retract the footrest and move the backrest and seat to normal or upright position.
A wall-avoiding chair comprising in combination, a base, a seat, first linkage means mounting the seat relative to the base for movement between normal and reclining positions, a backrest, second linkage means mounting the backrest relative to the seat for movement relative to the seat between a generally upright position and a reclining position where the backrest extends at an incline relative to the seat, a footrest, third linkage means mounting the footrest for movement between a retracted position adjacent the seat and an extended position projected forwardly from the seat, a control handle connected to the third linkage means for moving the same between extended and retracted positions thereof, fourth linkage means connected between said first and third linkage means for moving the seat forwardly with wall-avoiding action relative to the base in response to movement of the footrest to extended position.
A linkage system for a wall-avoiding chair of the type including a base, a seat movably mounted on the base for wall-avoiding movement, a backrest connected to the seat and movable relative to the seat between generally upright and reclined positions by the occupant exerting back pressure on the backrest, a footrest movable between a retracted position adjacent the seat and an extended position projected forwardly of the seat;
A wall-avoiding chair comprising in combination, a base, a seat including rigid armrests, a first linkage means mounting said seat on the base for wall-avoiding movement, a backrest, second linkage means mounting the backrest relative to the seat for movement between generally upright and reclining positions, a footrest, third linkage means mounting the footrest relative to the seat for movement between extended and retracted positions, first actuating means for actuating said third linkage means to move the footrest between said extended and retracted positions thereof, second actuating means connected to said third linkage means for moving said first linkage means to impart initial wall-avoiding movement to the seat when the footrest is moved from retracted to extended position, and third actuating means including linkage connected to the backrest and to said first linkage means for imparting further wall avoiding movement to the seat following the initial movement and when the backrest is moved into a reclining position relative to the seat.
