Abstract
A self-directed seating support and posture control assembly operable between fully seated and erect posture positions. A hand operated, hydraulic lift mechanism pivotally supports a cushioned seat and folding linkage from a base framework. A forward positioned upright utility platform includes a heighth and tilt adjustable tabletop. Depth controllable, cushioned knee/calf and mid-section supports extend from the platform uprights. An accessory, upper body exerciser detachably mounts to the chair back at pivotally mounted arm rests.
Claims10
Seating support apparatus comprising:
- a) a support framework having a fore and an aft end and including a plurality of frame members coupled to one another to form a base portion, an upright extensible means secured to said fore end and first and second stationary uprights mounted adjacent one another along one side of the framework;
- b) a tabletop secured to said extensible means;
- c) a cushion projecting from said extensible means and coupled to at least one arm having a plurality of notches in one surface and wherein said arm is mounted relative to a pair of pins secured to said extensible means such that a first one of said pins pivotally supports said arm relative a second pin which is selectively mountable within one of said plurality of notches upon rotating and extending said arm relative to said first pin and whereby the knees and calves of a user are selectively supported via said cushion;
- d) hydraulic pump means secured to said framework adjacent said first and second uprights including a hand pump lever and pressure release means for extending and retracting a piston;
- e) a support framework including a first member pivotally mounted between said first and second uprights, means for pivotally coupling said piston to said first member, a seat portion, a backrest portion, a follower member pivotally secured at one end to one of said first and second uprights and at an opposite end to said backrest portion, and wherein said seat portion is rigidly secured at a fore end to said first member and pivotally secured at an aft end to said backrest portion such that movement of the piston rotates said first member and seat portion with the backrest portion rotating in unison via said follower member between a first planar orientation wherein said seat and backrest portions are transverse to each other and a second planar orientation wherein said seat and backrest portions are parallel to one another.

Seating support apparatus comprising:
- a) a support framework comprised of a plurality of frame members coupled to one another to form a base portion and having fore and aft ends and including first and second columns, each column being comprised of a pair of upright frame members mounted in extensible relation to each other and the fore end, and third and fourth upright members mounted adjacent one another along one side of said framework;
- b) a tabletop mounted to said first and second columns;
- c) means transversely projecting from said first and second columns including a cushion for selectively extending said cushion to restrain the knees/calves of a user;
- d) means secured to said framework adjacent said third and fourth upright members including a hand pump lever and a hand release lever for raising and lowering a piston;
- e) support means including a seat portion, a backrest portion, means for pivotally coupling said piston to said seat, a follower member pivotally secured at one end to one of said third and fourth uprights and at an opposite end to said backrest portion, and wherein said seat portion is pivotally secured at a fore end to one of said third and fourth upright members and pivotally secured at an aft end to said backrest portion such that movement of the piston rotates said seat portion with the backrest portion rotating in unison via said follower member between a first orientation wherein said seat and backrest portions are transverse to each other and a second orientation wherein said seat and backrest portions are parallel to one another.
