Abstract:
An assistive seating device ( 10 ) includes a frame ( 11 ) having a base ( 12 ) with rear legs ( 14 ) coupled to front legs ( 15 ) having lifting arms ( 21 ). The base also includes a first couplers ( 25 ) and second couplers ( 26 ). The frame also includes a seat portion ( 29 ) coupled to the base for reciprocal movement between a lowered, seating position and a raised, lifting position. Lifting cylinders ( 40 ) are pivotally coupled at a top end ( 41 ) to the seat portion. Each lifting cylinder also has a lower end ( 44 ) receivable within either the first or second tubular coupler. The force of the lifting cylinders upon the pivoting seat portion depends upon the selected coupling location of the lower ends of the lifting cylinders upon the base. The assistive seating device also includes a lock to prevent the seat portion from pivoting from its lowered, seating position to its raised, lifting position.

Claim (Index 22):
An assistive seating device comprising,\n a base having a pair of rear lower couplers adjacent a rear of said base and a pair of front lower couplers adjacent a front of said base; a seat portion pivotally coupled for reciprocal movement to said base, said seat portion having a pair of upper pivot mounts, the distance between said upper pivot mounts and said pair of rear lower couplers being generally the same as the distance between said upper pivot mounts and said pair of front lower couplers; a pair of laterally disposed lifting cylinders, each lifting cylinder having a first end coupled to said seat portion through said pivot mounts and a second end selectively coupled to said base at either one said rear lower coupler of said pair of rear lower couplers or one said front lower coupler of said pair of front lower couplers, whereby each lifting cylinder is selectively coupleable to the seat portion and the base at a plurality of different elevational angles which determines the lifting force of the lifting cylinders upon the seat portion, and whereby the distance between the pivots and the rear lower couplers and front lower couplers are the same so that a tilting of the seat portion does not occur should one lifting cylinder be coupled to a rear lower coupler and the other lifting cylinder be coupled to a front lower coupler.
