Abstract: The invention is based on an apparatus for adjusting a vehicle seat, the position of which can be adjusted via one or more geared motors (8, 38, 41, 42), wherein the geared motors (8, 38, 41, 42) can be actuated via a control (24). A vehicle seat underbody (3, 32, 45) is supported at at least three points by means of driven lifting spindles (16), driven guide bars (28, 39, 40) or sliding fixtures (34, 35, 43), wherein at least one support point (16, 29, 34) can be varied relative to the other remaining support points of the vehicle seat in such a fashion that a spherical seat adjustment results.

Abstract: The ergonomic chair of the present invention provides a seating system that allows an occupant, while seated, to shift his or her position while exercising major muscle groups. The present invention chair includes a seat support frame that supports a seatrest and a backrest. The seatrest and the backrest are connected so that they can pivot relative to each other. The backrest of the invention chair can move along backrest tracks mounted to the frame between a lower resting position and a raised extended position. Because the seatrest is hinged to the backrest, it moves with the backrest by translating and rotating in relation to the frame. The seatrest is supported by the seat support frame so that the seatrest can slide and rotate in relation to the seat support frame. The occupant of the invention chair can push against the backrest, translate the backrest along the backrest tracks, stretch out into the extended position and then return to the resting position.

Abstract: A wheelchair is provided, having a recline mechanism for the chair back and wherein the seat is repositioned forward in response to recline to reposition the user's weight relative to the supporting wheels. The chair is also independently equipped with a weight-shifting tilt mechanism. Moreover, a bilateral tracking mechanism (i.e., controlled motion is transmitted to both sides) is used to reposition the seat. This avoids torque due to uneven loading of the chair. Back canes of the chair and/or brackets on the chair back are slotted to enable infinite adjustment of chair arms, ventilator trays, and other accessories.

Abstract: A chair seat tilt lock mechanism has a detent to latch an actuating lever in a locked and unlocked position. When the lever is moved to a locking position, a spring urges a moveable locking member toward a locking position, however, the moveable locking member only moves to its locking position when the chair is tilted to properly register the moveable locking member with a fixed locking member. When the lever is moved to an unlocking position, another spring urges the moveable locking member to an unlocking position. The moveable locking member may be a slider which slides under a fixed abutment to lock the chair from tilting. Alternatively, the moveable locking member may be a pivoting arm with a series of openings which may receive the forked end of a tongue in a locked position.

Abstract: A simplified reclining mechanism, as for chairs and seating, is herein described. The balanced design of such a reclinable chair for yard or patio usage is herein described. The reclining mechanism is an integral part of the chair or seat. The contoured design of the seat, back, legs and headrest gives firm, comfortable support to all parts of the body in both positions. What makes this chair stand above the rest is its unique 2 position balanced design. In the upright position it functions as a chair with head and legrest. Balance is the key to this design. By slightly throwing or shifting your weight backwards, this chair teters, giving a feeling of weightlessness and falling backwards until it lands solidly on its rear legs. In this position, every part of the occupant's body is cradled by the design. This chair also has the health advantage of having your legs lifted and held at heart level.

Abstract: A chair including a power-assisted linear actuation drive mechanism having a cam guide which is linearly movable upon retraction of a shaft for selectively actuating a lift and tilt linkage mechanism, and for causing forward lifting and tilting movement of the chair when a motor of the mechanism is operated in a first direction. Extension of a shaft in a second opposite direction acts to lower the chair to a normal seating position. Continued extension in the second direction causes a first cam block pivotably mounted to the cam guide to engage a first follower assembly for causing extension of a leg rest assembly. Further extension in the second direction causes a second cam block pivotably mounted to the cam guide to engage a second follower assembly for causing reclining movement of the chair. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.

Abstract: The chair disclosed includes a power-assisted linear actuation drive mechanism having a lead screw nut which is linearly movable upon rotation of a power screw for selectively actuating the lift and tilt linkage mechanism for causing forward lifting and tilting movement of the chair when the motor is operated in a first direction. Rotation of the screw shaft in a second opposite direction acts to lower the chair to the normal seating position. Continued rotation in the second direction causes a first cam block pivotably mounted to the lead screw nut to engage a first follower assembly for causing extension of the leg rest assembly. Further rotation in the second direction causes a second cam block pivotably mounted to the lead screw nut to engage a second follower assembly for causing reclining movement of the chair. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.
