2142194 9403087 PCTABS00030 A lift seat (10) includes a seating surface (12), for example, a toilet seat, mounted on a supporting frame (14) by a four-bar linkage (16, 18). The four-bar linkage includes a lower link (60) fixed to the frame and an upper link (68) fixed to the seat. An armrest (20, 22) is attached to a front link of the four-bar linkage for pivoting therewith against the bias of the spring (100) which loads the four-bar linkage as the seat is lowered from a raised position in a seating position. Energy stored in the spring is then available to lift the person from the seating position back to the raised position. A damper (140) is connected to the four-bar linkage to prevent abrupt movement of the seat as the four-bar mechanism collapses and expands, while a gas spring (120) is provided to initially resist movement of the four-bar linkage from either the expanded or the collapsed condition unless the armrest is initially rotated.
