Abstract:
PCT No. PCT/US93/07476 Sec. 371 Date Feb. 9, 1995 Sec. 102(e) Date Feb. 9, 1995 PCT Filed Aug. 10, 1993 PCT Pub. No. WO94/03087 PCT Pub. Date Feb. 17, 1994A lift seat includes a seating surface, for example, a toilet seat, mounted on a supporting frame by a four-bar linkage. The four-bar linkage includes a lower link fixed to the frame and an upper link fixed to the seat. An armrest is attached to a front link of the four-bar linkage for pivoting therewith against the bias of the spring 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 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 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.
