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 is disclosed having a frame with two side portions, a seat and a folding mechanism. The folding mechanism has coupling connections, pivoting connections and a cross-strut with two bars crossing at a pivot point. First ends of each of the cross-strut bars are mounted rotatably on the side portions of the frame via the pivoting connections. Second ends of each of the cross-strut bars are releasably mounted on the other of the two side portions of the frame via the coupling connections. A distance between the frame side portions may be modified if the cross-strut bars second ends are released from the frame side portions. The cross-strut bars are pivoted relative to each other about the pivot point. The cross-strut extends from the first ends to the second ends of the bars in a cross-strut direction which, in the operating position, extends substantially along the seat.

An object is to make it easier to lift and move a wheelchair by keeping casters from hanging even when the wheelchair is lifted by one hand.

To this end, a wheelchair includes a folding mechanism that couples a left-side support arm and a right-side support arm foldably in a left-right direction of the vehicle body. The folding mechanism includes an operation part for use in changing a state of a left-side support arm and a right-side support arm from one of a folded state or an unfolded state to another. The operation part is arranged between a rear drive wheel and a caster in a side view of the vehicle body.

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.

It is an object to improve riding comfort of a wheelchair having a folding mechanism by keeping an operation part of the folding mechanism from contacting a wheelchair user seated. A folding mechanism includes an operation part for use in changing a state of a left-side support arm and a right-side support arm from one of a folded state or an unfolded state to another. The operation part is arranged below an upper end part of a seat frame with a predetermined space therebetween.

A multifunctional mobility device includes a frame that is configurable between a plurality of modes corresponding to at least a power wheelchair mode, a power scooter mode, and a power walker mode, a plurality of motorized wheels mounted to the frame, and handles pivotally coupled to the frame and communicatively coupled to the plurality of motorized wheels. Pivoting the handles operates the plurality of motorized wheels, wherein each handle is independently pivotable to independently drive rotation of a motorized wheel of the plurality of motorized wheels.

A multifunction mobility device includes a frame that includes a seat member, a first wheeled leg ember coupled to a first side of the seat member and a second wheeled leg member coupled to a second side of the seat member. The first wheeled leg member and the second wheeled leg member each includes an upper leg portion pivotally coupled to the seat member at a distal end and defining an upper arm recess, and a lower leg portion pivotally coupled to the upper leg portion, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode where the upper leg portion is pivoted relative to the lower leg portion such that the lower leg portion nests into the upper arm recess.

A backrest assembly of a wheelchair seat has a tubular seating frame. The backrest assembly includes a backrest, two hollow backrest tubes connecting the backrest to the seat, and at least two joints allowing movement of the backrest tubes between at least first and second end positions. Two locking means are provided for locking and/or unlocking the joints. A hollow handle tube has a single handle for effecting the locking means which is arranged between the backrest tubes and mechanically connected to the locking means via cables. The handle further effects movement of the backrest tubes, via the joints, with use of one hand in constant grip of the handle. The handle is actuated by at least partly sliding, rotating, squeezing, pushing and/or pulling. The locking means automatically re-locks after unlocking and reaching the first or second end positions.

Systems and methods for a multi-function mobility device to provide cargo container transport are provided. A multi-function mobility device includes a frame configurable between a plurality of configurations. The frame includes a plurality of individually controllable wheeled leg members configured to traverse uneven terrain. The mobility device is configured to transform the frame into a cargo transport configuration that accepts two stacks of cargo bins locked together. The mobility device is also configured to transform the frame into a rideable configuration that accepts a person.

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.
