A mobile object is configured so as to be capable of moving front and rear bases 10,30 object to each other in order to make a wheel base provided between the front wheels 12 and the rear wheels 32 expandable and contractible. The front base 10 moves so as to be expand and contract the tread width between the front wheels 12 in association with the expansion and the contraction of the wheel base achieved. The seating part 41 is configured so as to turn forward in association with the relative movement of the front and rear bases 10,30 in order to contract the wheel base and the tread width. The seating part 41 is configured so as to turn backward in association with the relative movement of the front and rear bases 10,30 in order to expand the wheel base and the tread width.

A wheelchair incorporated with a lift apparatus is disclosed. The wheelchair comprises a pair of seat frame support bars, backrest support bars, and armrest frame support bars for supporting at least one seat cushion, backrest cushion, and armrest cushions. The wheelchair further comprises lower support bars positioned parallel and opposite each other on both sides of the wheelchair. The support assembly includes a plurality of scissor links pivotally connected to each other, and an end of the plurality of scissor links is pivotally affixed with needle bearings to the lower support bars and the seat frame support bars. The lift apparatus includes one or more actuators, positioned between the lower support bars and at least one scissor link on both sides. The actuators are configured to raise and lower the seat cushion by raising at least one scissor link, thereby raising and lowering the seat cushion to a desired adjustable height for the user.

A foldable walker having an arcuate front and rear leg frames pivotably connected by a hinge which permits the two leg frames to covert from an open configuration, with the front wheels engaging the ground and spaced a first distance from the rear wheels, to a folded configuration with the front wheels closer to the rear wheels. The walker includes a seat which can convert from a horizontal seat position to a vertical backrest position, and a height adjustable and pivotable foot rest.

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 wheelchair includes: a chassis configured to collapse in a width direction of the wheelchair; at least one wheel carried by the chassis; a seat assembly including a seat and a back support carried by the chassis, the back support defining a tilt angle relative to the seat and being pivotable to adjust the tilt angle; and a tilt assembly carried by the chassis and including at least one tilt actuator coupled to the back support, the at least one tilt actuator being configured to pivot the back support and adjust the tilt angle. The chassis is collapsible in the width direction while carrying the at least one actuator to reduce a width of the wheelchair.

A personal mobility vehicle, such as a stroller, has spaced apart side frame assemblies that each include a backrest portion and a seat frame portion. The backrest portion is moveable to several recline positions relative to the seat frame portion by actuating a latching mechanism. The backrest portion and the base frame are both moveable to a folded position relative to the seat frame by actuating the same latching mechanism. The side frame assembly further has a tilt mechanism that permits the backrest and seat frames to move as a unit relative to the base frame.
