A modular linking system provides a positioning and supporting structure for mounting various components, particularly on a wheelchair structure. A wheelchair kit includes such a modular linking system and further wheelchair includes at least one modular linking system or at least one wheelchair kit.

A convertible wheelchair is provided. The convertible wheelchair can have a wheelchair configuration and a walker configuration to allow a user to alternately sit and stand, and can include a frame supporting a chair. The chair can be foldable and can include a chair back and a chair seat. The convertible wheelchair can include support and stability mechanisms accessible in the wheelchair configuration and the walker configuration including one or more torso supports, a fall seat, and stability bars.

A lifting mechanism has a base to which a pivot of a parallelogram structure. A spring extends from a first link of the parallelogram to an adjustable termination point on a second link of the parallelogram to form a lifting triangle. The spring termination point is displaced from a main pivot of the parallelogram to create an adjustable “lever arm” to vary the lifting force. A lifting power adjustment mechanism adjusts the position of the spring termination point. An extension is in fixed relation to one of the parallelogram links and maintains its angle with respect to the horizontal when angles of the parallelogram are varied upon raising or lowering the lifting mechanism between a sitting mode and a standing mode. The extension serves as a base for a rear seat section. A front seat section is pivotally attached to the rear seat section allowing it to swing downward upon elevation of the lifting mechanism.

An electric mobility vehicle including a front-wheel-side body, a rear-wheel-side body, a seat on which a passenger sits in an in-use state, and a linking mechanism that links the front-wheel-side body with the rear-wheel-side body so as to be pivotable about a pivoting axis extending in a vehicle width direction. The electric mobility vehicle is foldable by pivoting the front-wheel-side body and the rear-wheel-side body relative to each other in a vehicle front-to-rear direction. The electric mobility vehicle includes a footrest provided in the front-wheel-side body, a front-end roller or a front-end caster provided in the front-wheel-side body and disposed at a vehicle front side relative to a front end of the front wheel in the in-use state, and comes into contact with the floor surface in the folded state to make the electric mobility vehicle stand alone.

A patient transport apparatus operable by a user for transporting a patient along stairs. A seat section is coupled to a support structure supporting a track assembly having a belt. A motor selectively generates torque to drive the belt. A user interface is arranged for engagement by the user, and has a direction input control for selecting a drive direction of the motor, and an activation input control for operating the motor to drive the belt. A controller in communication with the motor and the user interface is configured to limit operation of the motor in response to user engagement of the activation input control preceding engagement of the direction input control to prevent driving the belt, and to permit operation of the motor in response to user engagement of the activation input control following engagement of the direction input control to drive the belt in a selected drive direction.

A wheeled personal conveyance has a rear portion and a front portion, the front portion being configured to receive into the wheeled personal conveyance the rear portion of a like wheeled personal conveyance such that the like wheeled personal conveyance is at least partially nested within the wheeled personal conveyance. By one approach, a body frame as comprises the wheeled personal conveyance has a front portion that is laterally wider than a part of the body frame that comprises a part of the aforementioned rear portion of the wheeled personal conveyance. So configured, the wheeled personal conveyance can have a passenger area that is wider towards the front than towards the back. By one approach, arm rests are provided that connect to a seat of the wheeled personal conveyance and that move in conjunction with the seat as the seat pivots.

A foldable electric wheelchair that includes an array of support frame members strategically joined together at hinge joint points to allow the support user seat, a back support frame, a main support frame and a lower support frame to be easily manually folded into an array that are substantially parallel in the same plane occupying a small volume. The electric motors are powered by a pair of batteries each of which is mounted inside hollow main frame support members out of the way to reduce the overall volume and weight of the electric wheelchair

A folding wheelchair comprising a luggage compartment, a collapsible frame and wheels, the wheels being mounted to a chassis of the collapsible frame for supporting the folding wheelchair in use, the collapsible frame having a first support pivotally mounted to the chassis at a first end of the first support, the first support and chassis being configured to rotate relative to one another between a stowed position, in which the chassis and the first support are adjacent, and an erect position in which the first support extends away from the chassis to support a seat and handles for pushing the folding wheelchair.

A rollable user-support device comprising a rigid frame with first legs and second legs, each with a rollable and swivelable wheel, a seat with a seat folding mechanism and/or a seat manipulation mechanism. The seat manipulation mechanism can be operable to move the seat, with a user seated thereon, between a lower rearward seating position and an elevated forward seating position, and the seat folding mechanism can be operable to move the seat between the elevated forward seating position and a folded position, at least one of the devices being connected to a swivel prevention mechanism associated with the first wheels. The device can constitute a bi-directional rollable user-support device operable in three modes.

A folding electric wheelchair with elevating seat that provides the user an electronic driving system powered by two lithium-ion batteries that is sealed to be weatherproof, able to drive over different terrain types and slope grades on any given day whether it's raining or sunny, lightweight, and portable for transportation, travel-friendly, compact in overall size when in the folded position to fit into a small space for storage. An ergonomically contoured seat with an actuator that can raise and lower the seat base overall height. A bump dampening and terrain vibration system with the supporting frame pieces (34), (42), and (50) having an oval shape. The manner of how the embodiment operates to fold and unfold consists of specific hinge joint embodiments including: (46), (48), (58) and (64).
