Total Claims: 17
Claim 1
Independent Claim
277 words
A reclining chair having relatively moveable base, seat and back portions and an extensible and retractable legrest, said chair being operable between an upright position with the legrest retracted, a semireclined position with the legrest extended, and a fully reclined position with the back portion tilted rearwardly with respect to the seat and base portions; interconnecting means between the base, seat and back portions for actuating the seat portion to a raised, fully reclined position with respect to the base portion as the back portion is tilted to its fully reclined position; said interconnecting means including an expandable and contractable linkage between the base and seat portions; said linkage being expandable to move the seat portion to the raised position in response to rearward tilting of the back portion and including a pair of support links each having one end operatively connected with the base portion and its other end operatively connected with the seat portion, each of said other ends being swingable about its respective one end upon movement of the seat portion to its raised position relative to the base portion; said support links being pivotally connected to each other intermediate their ends for movement between an expanded position when the seat is in its raised position and a collapsed position when the seat portion is not in the raised position; a base bracket mounted on the base portion, said one end of said support links being connected with said base bracket; said one ends of said support links being pivotally connected with said base bracket; and said one end of at least one of said support links being slidably connected with said base bracket.
Claim 2
Dependent Claim
277 words
A reclining chair having relatively moveable base, seat and back portions and an extensible and retractable legrest, said chair being operable between an upright position with the legrest retracted, a semireclined position with the legrest extended, and a fully reclined position with the back portion tilted rearwardly with respect to the seat and base portions; interconnecting means between the base, seat and back portions for actuating the seat portion to a raised, fully reclined position with respect to the base portion as the back portion is tilted to its fully reclined position; said interconnecting means including an expandable and contractable linkage between the base and seat portions; said linkage being expandable to move the seat portion to the raised position in response to rearward tilting of the back portion and including a pair of support links each having one end operatively connected with the base portion and its other end operatively connected with the seat portion, each of said other ends being swingable about its respective one end upon movement of the seat portion to its raised position relative to the base portion; said support links being pivotally connected to each other intermediate their ends for movement between an expanded position when the seat is in its raised position and a collapsed position when the seat portion is not in the raised position; a base bracket mounted on the base portion, said one end of said support links being connected with said base bracket; said one ends of said support links being pivotally connected with said base bracket; and said one end of at least one of said support links being slidably connected with said base bracket.
Claim 3
Dependent Claim
118 words
A reclining chair having relatively movable base, seat and back portions and an extensible and retractable legrest; an expandable and contractable linkage between the base, seat and back portions for selectively operating the chair between an upright position in which the seat and back portions are in the normal seating positions and the legrest is retracted; a semireclined position iN which the seat portion is shifted rearwardly with the back portion remaining substantially in an upright position and the legrest is extended; and a fully reclined position in which the seat portion is in a raised position with respect to the base portion with the back portion tilted rearwardly to a reclined position and the legrest is extended.
Claim 4
Dependent Claim
118 words
A reclining chair having relatively movable base, seat and back portions and an extensible and retractable legrest; an expandable and contractable linkage between the base, seat and back portions for selectively operating the chair between an upright position in which the seat and back portions are in the normal seating positions and the legrest is retracted; a semireclined position iN which the seat portion is shifted rearwardly with the back portion remaining substantially in an upright position and the legrest is extended; and a fully reclined position in which the seat portion is in a raised position with respect to the base portion with the back portion tilted rearwardly to a reclined position and the legrest is extended.
Claim 5
Dependent Claim
