A motorized lifting and transfer chair includes a base having a front portion and an opposing rear portion, where the rear portion has a pair of foot rests. The chair also includes a plurality of wheels mounted to the base configured to be selectively locked, and a vertical post assembly secured proximate to the rear portion of the base and extending upwards from the base. In addition, the chair includes a seating platform cantilevered from the vertical post assembly, where the seating platform comprises two portions with an aperture formed along two adjacent edges of the two portions and the two portions are configured to swing open and closed about the vertical post assembly. The chair includes a motorized device that raises and lowers the seating platform, and a latch is configured to secure the two portions of the seating platform closed.

A seat apparatus for facilitating movement of a user from a sitting position to a standing position is provided. The seat apparatus includes a main body having a bottom surface, a back wall and a pair of lateral walls which are connected together and define a recessed region configured for sitting in. The main body further includes a seat projection extending upwardly from the bottom surface, between the lateral walls, whereby the seat projection is shaped and adapted to maintain thighs of a user separated on either side thereof. The seat apparatus also comprises a base provided below the main body and adapted to cooperate therewith. At least one of the base and main body has a convex and curved cross-sectional profile adapted to allow the apparatus to pivot about at least one axis in order to tilt the main body forward and urge a user in the standing position.

A rear side entry type wheelchair includes a driving device comprising a pair of driving frames provided on left and right sides thereof and driving wheels provided in the driving frames, respectively, a seat device including a pair of horizontal frames coupled to the driving device and saddles configured to be rotated about a vertical shaft on surfaces of the horizontal frames, a back support device including a back support opening/closing interworker provided on a rear side of the seat device and a back support provided in the back support opening/closing interworker configured to be foldable so as to be opened and closed, and a handle device provided on a front side of the seat device.

An external structural brace apparatus for supporting a user in a semi standing position on a surface includes first and second support extension beams that to attach to the surface, also included is a channel having a base with first and second legs, wherein the first and second legs extend in the same direction from opposing sides of the base, the first leg is affixed to the first support structure and the second leg is affixed to the second support structure, the channel can be lockably positioned along the first and second beams. In addition, a saddle seat with a midpoint extension portion, the saddle is attached between the first and second legs and positioned such that the midpoint extension extends opposite of the base, wherein operationally the user partially rests their buttocks on the saddle and leans their back against the base to assume a semi supported standing posture.

The invention concerns a wheelchair for assisting walking. The wheelchair comprises a chassis, a movable base that can move relative to the chassis between a low seating position and a high walking position, and a device for changing the position of the base. The device for changing the position comprises at least a first arm and a linear actuator. The arm forms a third-class lever. The linear actuator is configured to bias the movable base towards the high position by means of the arm.

An automatically adjusting comfort method includes measuring pressure applied by a user via a pressure-sensor array, determining a pressure profile based on measurements from the pressure-sensor array, comparing the pressure profile to a first limit, determining a cumulative pressure profile over a predetermined duration, comparing the cumulative pressure profile to a second limit, and adjusting one or more of a plurality of adjusting mechanisms configured to alter the pressure profile for increased comfort of the user when the pressure profile exceeds the first limit or the second limit. An automatically adjusting comfort system includes a pressure-sensor array communicatively coupled to a controller for determining a cumulative pressure profile over time, and a plurality of adjusting mechanisms configured to alter the pressure profile to increase a user's comfort, wherein the controller automatically adjusts one or more of the plurality of adjusting mechanisms based on the cumulative pressure profile.

A wheelchair includes massaging units integral with both the seat and the backrest. A first massaging unit includes a plurality of vibrating members positioned about the periphery of the backrest that can be activated simultaneously, sequentially, individually or in a random pattern to knead the user's back, shoulders and neck. A second massaging unit includes motorized massaging discs that rotate and linearly reciprocate to provide a unique “rolling” massage to the buttocks and thighs.

An external structural brace apparatus for supporting a user in a semi standing position on a surface includes first and second support extension beams that to attach to the surface, also included is a channel having a base with first and second legs, wherein the first and second legs extend in the same direction from opposing sides of the base, the first leg is affixed to the first support structure and the second leg is affixed to the second support structure, the channel can be lockably positioned along the first and second beams. In addition, a saddle seat with a midpoint extension portion, the saddle is attached between the first and second legs and positioned such that the midpoint extension extends opposite of the base, wherein operationally the user partially rests their buttocks on the saddle and leans their back against the base to assume a semi supported standing posture.

A wheelchair lift assembly includes a wheelchair. The wheelchair has a pair of seats and a frame. Each of the seats is hingedly coupled to the frame. Each of the seats is positionable in a stored position having each of the seats being horizontally oriented on the frame. Each of the seats is positionable in a lifted position having the each of the seats hinging upwardly from the upper front member. A lifting unit is coupled to the wheelchair. The lifting unit selectively urges each of the seats between the stored position and the lifted position. Thus, the lifting unit may lift a user thereby facilitating the user to exit the wheelchair.

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.
