Dynamic furniture for supporting a seated or reclining user includes a base, an actuator assembly supported by the base, a front boom in circular orbital connection to a portion of the base, a rear boom in circular orbital connection to another portion of the base, a seat platform supported by the actuator assembly, and a back platform supported by the actuator assembly. The seat platform and the back platform are capable of remaining stationary relative to the actuator assembly while the actuator assembly moves relative to the base. The seat platform and the back platform are also capable of moving relative to the actuator assembly while the actuator assembly remains stationary relative to the base. The seat platform and the back platform are also capable of moving relative to the actuator assembly while the actuator assembly moves relative to the base.

A wheelchair apparatus is provided for raising and lowering a user of the wheelchair, while allowing the user to manually move the wheelchair at any height.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame.

The present invention discloses a moving mechanism including a support; a driving device mounted on the support; a controller arranged on the support; two sets of moving assemblies respectively mounted at two ends of the support; wherein each of the moving assemblies includes a track and two synchronous wheels of different diameters arranged inside the track, such that the moving mechanism could be functioned and run freely over stairs, rugged road surface and all-terrain ground under the action of the driving device and the controller. The present invention also discloses electric vehicles and toys equipping the moving mechanism. The moving mechanism of the present invention overcomes shortcomings of conventional moving mechanisms by making use of a breakthrough composite structure of a half-wheel-half-track configuration in combination with an additional omni-directional wheel, whereby the moving mechanism and the electric vehicles and toys equipping the same are adaptable to different road surfaces and stairs of various angles, and also very convenient and reliable to use.

An adjustable wheelchair includes a base frame having a first guide portion defining a first arcuate channel, and a seat frame having a second guide portion defining a second arcuate channel confronting the first arcuate channel. A first bearing assembly is secured to a front end of the first arcuate channel and extends into bearing engagement with the second arcuate channel. A rear bearing assembly is secured to a rear end of the second arcuate channel and extends into bearing engagement with the first arcuate channel. The seat frame is slideable in an arcuate path defined by the first and second arcuate channels for adjustment of a tilt angle of the seat frame with respect to the base frame.

Embodiments herein are directed to systems and methods of a wheelchair that includes a frame and a pair of armrests. The pair of armrests includes an arm pad, a sleeve configured to store a plurality of telescoping segments, and a pivot portion positioned between the arm pad and the sleeve. The plurality of telescoping segments is configured to extend in a system vertical direction. The pair of armrests is releasably coupled to the frame at the sleeve via a release mechanism. The pair of armrests is pivotable between a first position and a second position wherein when in the first position the pair of armrests is in an armrest position and in the second position the pair of armrests is pivoted in the system vertical direction such that the pair of armrests is a pair of crutches independently operable from the wheelchair.

By programming position parameters corresponding to user support surfaces of a power driven wheelchair, movement of the user support surfaces is automated. The user support surfaces can be positioned individually, as part of a sequence or as part of a series of sequences. Accordingly, with little effort, a user can position the user support surfaces of the wheelchair to a predefined position.

An adjustable chair assembly comprising a frame, a seat assembly, a back assembly and at least one of a seat space-filling element and a back space-filling element. The seat assembly extends along a seat plane and comprises a first seat element and a second seat element adjustably positionable with respect to one another along the seat plane and together defining a support surface of the seat assembly. The back assembly extends along a back plane and comprises a first back element and a second back element adjustably positionable with respect to one another along the back plane and together defining a support surface of the back assembly. A central gap is defined in at least one of the support surfaces and the at least one of the seat space-filling element and the back space-filling element is removably insertable in the central gap of the corresponding support surface.

A medical chair having a plurality of adjustable positions includes a seat, a platform configured to support the seat, and a pillar. The pillar includes nested supports, in which a first one of the supports is fixedly coupled to the platform and a second one of the supports is operatively coupled to the seat, wherein the nested supports extend telescopically as the seat is positioned with respect to the platform. A linked cable carrier is located within a housing, wherein the housing extends from the base toward the seat and is disposed adjacently to the pillar. A leg rest and a back are each pivotably coupled to seat. A seat position actuator is centrally located on the seat and a leg rest actuator and a back actuator are located on opposite sides of the seat position actuator.

A combined lift and tilt system including a lower frame, an upper frame, a first lever arm rotatably connected to the lower frame, and a second lever arm rotatably connected to the first lever arm and to the upper frame and in sliding engagement with the lower frame. The system further including a first linear power source rotatably connected to the lower frame and to the first lever arm, and a second linear power source rotatably connected to the upper frame and to the second lever arm.
