Abstract
The present invention is an orthopedic chair which may be used to assist an invalid to easily sit therein or to rise therefrom. The orthopedic chair includes a frame and a seat which is pivotally coupled to the frame at the front thereof, a back which is mechanically coupled to the frame, a right arm-rest and a left arm-rest both of which are mechanically coupled to the frame. The orthopedic chair also includes a spring tensioning mechanism which resiliently biases the seat, when it is in its first position, toward its second position and a releasing mechanism which releases the seat so that the spring tensioning mechanism moves the seat from its first position to its second position.

An orthopedic chair comprising:
- a. a frame;
- b. a seat which is pivotally coupled to said frame at the front thereof;
- c. a back which is mechanically coupled to said frame;
- d. a pair of arm-rests which are mechanically coupled to said frame;
- e. a pair of a springs each of which has a first end which is mechanically coupled to the base of said frame;
- f. a pair of cables the first end of each of which is mechanically coupled to a second end of one of said springs;
- g. a pair of pulley systems, each of which includes two pulleys which are disposed in series and mechanically coupled to said frame above said seat and through each of which the second end of one of said cables is threaded and wherein the second end of each of said cables is securably coupled to said seat whereby said springs resiliently bias said seat, when it is in its first position, toward its second position so that said seat may be used to assist an invalid to easily sit therein;
