A wheelchair includes right and left side frames and a connection unit connecting the side frames to each other. The side frames each include a unit fixture for detachably fixing the connection unit. The connection unit is selectable from a foldable connection unit connecting the right and left side frames with a distance therebetween changeable or a non-foldable connection unit connecting the right and left side frames with the distance therebetween kept constant.

The present invention provides an assistive mobility device convertible between a rollator mode and a transport chair mode.

A folding wheelchair includes two side frames, which are connected to each other via a cross-strut. A fabric is stretched between the side frames in order to form a seating area of a seat. The side frames are formed identically and include an outer tube and an inner tube. The outer tubes have a slot extending in a longitudinal direction (L), which opens at least into an outer tube end. The inner tubes each include a slot extending in the longitudinal direction (L), which opens at least into an inner tube end. A tensioning rod is accommodated in one of the outer tubes and opens into the associated inner tube. The fabric is led to the outside through the slots of the inner tube and outer tube. The inner tube, the fabric and the tensioning rod are connected to one another.

A chair is disclosed having a chair frame and a seating surface having a first side surface movably coupled to the frame, and a second side surface coupled to the frame. The first side surface is independently moveable relative to the second side surface. Each of the first side surface and the second side surface define a front end of the seating surface and a back end of the seating surface. A first actuator is coupled to the frame, where the first actuator is configured for operative communication with the first side surface.

The present disclosure describes devices and systems that can be integrated with a foldable, manual wheelchair to convert the wheelchair into a hybrid chair capable of both manual operation and motor-powered operation. A wheelchair powering device includes a motor that is operatively coupled to a roller member so that rotation of the motor shaft causes rotation of the roller member. The roller member may be engaged against a tire of the wheelchair so that rotation of the roller member causes rotation of the tire via friction between the roller member and tire.

A wheelchair is provided which includes a body, and driving wheels arranged on the both sides of the body. The wheels include a rim portion, a hub portion, an hand rim, and fastening members. A tire is attached to the outer peripheral part of the rim portion. The hub portion is arranged at the center of the rim portion and coupled to the rim portion by connecting members. The hand rim is arranged along the rim portion on the exterior side of the rim portion. The fastening members fasten the hand rim to the rim portion. An insertion prohibition spacing is formed between the rim portion and the hand rim. The spacing has a distance capable of prohibiting insertion of user's thumb into this spacing.

A wheelchair is provided which includes link rods that intersect each other in an X shape, and are pivotably coupled to each other by a pivot shaft. The link rods include a rod central part, and rod upper and lower parts. The rod central parts hold the pivot shaft. The rod upper and lower parts and slant from first and second inclined parts on the both ends of the rod central part in opposite directions with respect to the rod central part. When the X-link portion is folded, the rod central parts overlap each other and are aligned in one straight line in the vertical orientation, and frame accommodation space portions which can accommodate the middle frame portions are provided on the both sides of the rod central parts.

The present invention provides an assistive mobility device convertible between a rollator mode and a transport chair mode.

A transferable wheelchair width adjuster that can be attached to the lower frame of a folding wheelchair allowing the wheelchair to be narrowed to varying widths so as to accommodate entry through doorways that otherwise would be impassable. Narrowing the profile of a standard wheelchair also allows the chair to accommodate more comfortably a smaller individual, such as a small child. No modification of the original wheelchair construction is necessary. The width adjuster described herein can be attached and removed manually without the need of tools.

A wheelchair includes right and left side frames and a connection unit connecting the side frames to each other. The side frames each include a unit fixture for detachably fixing the connection unit. The connection unit is selectable from a foldable connection unit connecting the right and left side frames with a distance therebetween changeable or a non-foldable connection unit connecting the right and left side frames with the distance therebetween kept constant.
