An electric mobility vehicle in a facility includes a mobility body having a wheel, a driving unit driving the wheel, and a seat for the user, and sensors, and the mobility body has a controller which controls the driving unit for at least one of automatic driving and automatic stopping by using detected data of the sensor, the controller is configured to be able to set a detection cancel area, which is an area where a part of the user can exist in front of the user, the electric mobility vehicle further includes a lower side sensor which detects an object to be avoided from under a footrest surface or from a front end portion of a footrest portion.

A ramp transportation system for a wheelchair enables transportation, deployment, and retrieval of a portable ramp by a single wheelchair occupant in the absence of external aid. The device comprises: a platform, configured to support the width of a wheelchair for crossing the platform, having a sufficient stiffness to support a wheelchair and occupant load; a lifting mechanism interface in the platform, disposed at least near each end of the ramp, configured to support cantilever lifting forces on the ramp; a lifting element, configured to engage the lifting mechanism interface and to apply a force to raise and lower the platform between a raised, stowed position and a lowered position, suitable for traversal; and a motor, configured to supply sufficient force on the lifting element to raise and lower the platform.

A rolling element such as a wheel and wheel attachment or caterpillar type rolling element for improving support. A rolling element includes: a first support surface formed as a loop configured to roll on a substrate such that a region of the first support surface alternately contacts and separates from the substrate, a first extension running about the loop and disposed about the first support surface, wherein where the rolling element is disposed on the substrate and a load is applied thereto: in a first region of the loop where the first support surface is separate from the substrate the first extension extends beyond the first support surface, and in a second region of the loop where the first support surface contacts the substrate the first extension is deformed so as to form a second support surface which contacts the substrate.

A support device includes a wheel, a base member, a leg coupled to the wheel and the base member, the leg including an upper leg segment, a lower leg segment positioned below the upper leg segment, a joint positioned between the upper leg segment and the lower leg segment, and an actuator engaged with the upper leg segment and the lower leg segment, where the actuator includes a linear engagement member that is engaged with one of the upper leg segment and the lower leg segment, a cammed member defining a non-circular perimeter engaged with the linear engagement member, and a motor engaged with the linear engagement member through the cammed member

A transport apparatus has a mobile chassis, a lifting mechanism, two armpit supports structured and operated mirror-symmetrical to one another, and two seat assemblies. The lifting mechanism includes a lifting arm for assembling a chest rest and two lifting racks, and a linear actuator driving the lifting arm to pivot upward or downward. The armpit supports are assembled on the lifting racks and transversely extend toward a rear of the mobile chassis. The seat assemblies are assembled on the mobile chassis. Each of the seat assembly has a seat plate driven to rotate by a drive motor to form a seat. The weak person can be moved directly by the transport apparatus with voice command or with a remote control. Since the weak person is not moved by the care workers, the weak person can be moved in an easier and safer way.

A support device includes a wheel, a base member, a leg coupled to the wheel and the base member, the leg including an upper leg segment, a lower leg segment positioned below the upper leg segment, a joint positioned between the upper leg segment and the lower leg segment, the joint including a cam defining a non-circular perimeter, and an actuator coupled to one of the upper leg segment and the lower leg segment, the actuator including an engagement member that is engaged with the non-circular perimeter of the of the cam of the joint, where the actuator selectively moves the engagement member to move the cam and the upper leg segment and the lower leg segment about the joint.

Embodiments of the present disclosure include 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, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters that can selectively engage the arm assembly dependent on the position of the arm assembly and surface conditions of ground and can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A modular power base for a wheelchair, the modular power base includes a leg module. The leg module includes an upper leg portion comprising a distal end and a proximal end. The proximal end is configured to be detachably and rotatably coupled to a seat portion of the wheelchair. The leg module also includes a lower leg portion having a first end and a second end, the first end of the lower leg portion being rotatably coupled to the distal end of the upper leg portion. The leg module also includes a first wheel rotatably coupled to the distal end of the upper leg portion and to the first end of the lower leg portion and a second wheel rotatably coupled to the second end of the lower leg portion.
