The present disclosure includes a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A convertible transport system including a seat portion, a back support portion, and a pivoting mechanism coupled to the seat portion and to the back support portion. The pivoting mechanism is configured to adjust and lock the back support portion relative to the seat portion, the pivoting mechanism having three operative states: a free pivoting state allowing the back support portion to pivot relative to the seat portion about an axis; a ratcheting state allowing the back support portion to only pivot toward the seat portion about the axis; and a locking state in which the pivoting mechanism is locked to thereby prevent a pivoting movement of the back support portion relative to the seat portion.

In order to satisfy a conventional demand from users for easily portable chairs that can be used in a variety of situations, a chair includes: a main body having a seat surface and capable of being installed on an installation plane; and a backrest rotatably attached to the main body. The chair is configured to have a box-like shape having one or more faces that are positioned so as to cover two lateral sides and an upper side of the seat surface in a folded state in which the backrest covers the upper side of the seat surface. The one or more faces are constituted by outer surfaces of the main body and an outer surface of the backrest. This chair can be easily carried to various places.

The material contained in this disclosure pertains to robotics related to convertible robots incorporating telecommunication elements. Embodiments of the system and apparatuses described can facilitate instant communication with family and friends, health status monitoring and support from caregivers; and promote optimal health, longevity, and independent living by providing high-tech economical solutions at each stage of the aging process. Embodiments of the system and apparatuses may be converted from an independent telecommunications robot, to a robotic walker, to a robotic wheelchair.

A wheelchair rear wheel support assembly and a detachable arm assembly is described. The rear wheel support assembly is adjustable by finite adjustment both in the horizontal and vertical planes whereby to adjust the position of the rear wheels at a center of gravity to suit a user person to optimize the efforts of propulsion of the wheelchair by the user and thereby significantly increasing its quality of life. The detachable armrest is easily adjustable in height and can be pivoted away from its position of use by simple hand-operating levers easily accessible to the user person. It can also be easily removed with little effort.

The leg support for a motorized chair is an accessory that is adapted to be mounted onto a motorized chair in order to support a leg of an end user that is riding said motorized chair. The leg support includes a first armature that is adapted to be affixed to and extend upwardly from a motorized chair floor surface. The first armature may employ the use of at least one mounting bracket to rigidly affix the first armature to the motorized chair. The first armature extends upwardly and includes a bend that designates a second armature portion. A leg rest is selectively bolted to the second armature portion. The leg rest is supported at a horizontal orientation with respect to the motorized chair. The leg rest includes at least one leg rest bracket to secure the leg rest to the second armature portion.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

An illustrated view of an exemplary walker device for a person necessitating the need of a walker and a wheelchair is presented. The walker device is light weight, foldable, provides contemporary conveniences and is cost efficient. The walker device can be further converted easily into a wheelchair.

An electric wheelchair according to an embodiment of the present disclosure includes a frame configured to support a seat, a driver configured to be coupled to a lower portion of the frame, armrests configured to be coupled to both sides of the frame, and a controller configured to be detachably coupled to the armrest, in which the controller is coupled so as to shield an opening formed in the armrest and is electrically connected to a connector located inside the armrest. The wheelchair includes a robot.
