A swing arm assembly for a foldable wheelchair consisting of a camber tube and adapters is disclosed. The adapters mount to the frame of the wheelchair and receive the ends of the camber tube. Each end of the camber tube is pinned into an adapter using a quick release pin. The camber tube improves the stability of the foldable wheelchair. When desired to fold the wheelchair, the quick release pin is removed and the camber tube is removed, thereby allowing the wheelchair to fold. The adapters may be mounted to the wheelchair frame or to stub axles if used. The swing arm assembly adds substantial stiffness and stability to a folding wheelchair.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a fixed arm coupled to the first and second frames; and a seat coupled to the frames with an angled surface mostly contacting the ischial tuberosities and adapted 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.

It is an object to make it easy to unfold a wheelchair simply by lifting a part of the wheelchair with one hand. A wheelchair includes a folding mechanism that folds a left-side support arm and a right-side support arm. The folding mechanism includes a grip part coupled to the distal end part of the left-side support arm and the distal end part of the right-side support arm. The grip part extends in the pivoting direction of the left-side support arm and the right-side support arm at a time of switching from a folded state to an unfolded state.

A rollator to aid mobility is described. The rollator comprises an A-frame with two pairs of uprights, each pair of uprights connected by at least one respective hinge to allow each pair of uprights to be folded or pivot front-to-back and a seat disposed between the two pairs of uprights, the seat foldable side-to-side. To fold compactly the rollator comprises an X-shaped cross-linkage comprising four linkage members. A method of manufacturing the rollator is also disclosed. The four linkage members may extend from a respective upright to a central hub underneath the seat. The cross-linkage may fold or pivot at the central hub in both front-to back and side-to-side dimensions when the rollator is folded away.

A portable wheelchair is collapsible for ease of development, handling and transport, while also providing a front steer configuration and a rear steer configuration.

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, walk or work for an extended period without requiring the user's arms to hold the frame. A motorized drive helps the user move with ease. The drive can be computer controlled.

A rollator is disclosed, including first and second upright members, each including handle portions, wheels, hinges disposed between the wheels and the handle portions, channels disposed along the upright members between the hinges and the wheels, and lateral hinges orthogonal to the hinges. First and second foldable support members having wheels are attached to the hinges. At least one lateral support member is disposed between and attached to the lateral hinges, and includes an intermediate hinge. Brake systems include brake lines communicating between brake controls and brakes. In a reversible storage configuration, the foldable support members are rotated to be at least partially disposed in the channels, and the lateral hinges and intermediate hinge rotate to collapse the lateral support member, bringing the upright members with the folded foldable support members adjacent to one another.

A wheelchair lifting system for transferring a wheelchair into and out of a vehicle includes a wheelchair that has a pair of rear wheels. A strap is provided and the strap may be manipulated. The strap is selectively extended through the spokes on each of the wheels. The strap engages the rim on each of the wheels to facilitate the wheelchair to be transferred into and out of a vehicle.

A handle device for use with a collapsible wheelchair, the wheelchair positionable between a first working position and a second collapsed position. The wheelchair having first and second generally horizontal handlebars extending rearward to facilitate movement of the wheelchair. The handle device comprising first and second substantially L-shaped members, each L-shaped member having a lower portion and an upper vertically oriented portion. The lower portion is adapted to receive the respective first and second horizontal handlebars therein. The upper portion extends substantially perpendicular to the lower portion, wherein the upper portion of each member upwardly extends beyond a height of the chair allowing the user to grasp each member without flexion of the torso.
