Patent abstract
A seat on a lift assist chair pivots between a lowered position in which a user can sit in the chair, and a raised position in which a seated user is helped out of the chair and into a standing position. A pair of arms is operatively attached to the seat. Responsive to the application of a user-applied downward force, the arms pivot about an axis thereby causing the seat to pivot between the lowered position and the raised position. First and second counterweights are also connected to the arms, and are axially adjustable relative to the axis about which the arms pivot. This movement permits the user to selectively alter the moment of the pivotable arms.
