RECLINING CHAIR WITH TILTING ACTION TO PROVIDE HEART-REST POSITION
First Claim
1. A reclining health-care chair, comprising:
- a base configured to rest on an underlying surface;
a frame including a pair of opposed arms;
a seat;
a backrest;
a footrest;
a tilting mechanism comprising a plurality of pivotally interconnected links, the tilting mechanism attached to the base and to the seat and configured to control movement of the seat relative to the base;
a reclining mechanism comprising a plurality of pivotally interconnected links, the reclining mechanism attached to the backrest, footrest, seat, frame and tilting mechanism to control relative movement of the backrest, footrest, frame and seat relative to the base; and
a power actuating unit attached to the seat and to the tilting mechanism;
wherein the chair is movable between (a) an upright position, in which the footrest is retracted beneath the seat, the seat defines an angle α
relative to the underlying surface, and the backrest defines an angle ε
relative to the underlying surface, and (b) a fully reclined position, in which the footrest is extended in front of the seat, the seat defines an angle γ
relative to the underlying surface that is greater than the angle α
, the backrest defines an angle δ
relative to the underlying surface that is less than the angle ε
, and the footrest is positioned such that an occupant'"'"'s feet are higher than the occupant'"'"'s heart.
