A wheelchair includes a removable seat assembly that slides laterally sideways to either side of the wheelchair for assisting a seated wheelchair occupant onto a receiving seat, such as a vehicle seat.

Novel mobility devices are disclosed wherein one embodiment comprises a support frame and one or more boosters coupled to the frame. The booster preferably comprises a housing, a top support extending upward from the housing, and an opposing bottom support extending downward from the housing. The bottom support is preferably biased toward the housing. The housing may contain a sleeve having a top channel in communication with an opposing bottom channel. The top channel is configured to receive the top support, whereas the bottom channel is configured to receive the bottom support, a retaining ring, and a spring. The spring is disposed between a floor of the bottom channel and the retaining ring. The sleeve may also have a socket configured to receive a roller, wherein the roller has a bottom hole configured to receive the top support. The device permits the user to stand from a seated position or vice versa without the assistance of a third party, grab hold of handlebars extending from the frame, and then move about with independence. The device may also be folded for ease of storage.

The present invention relates to a footrest device for a wheelchair, and more particularly to a footrest device and safety device for a wheelchair, in which a footrest provided in a lower side of the wheelchair moves up and down in accordance with a weight applied by a foot of a sitting person, thereby preventing a falling accident caused by stepping on the footrest when the sitting person rises from or sits in the wheelchair.

A parking device for a motorized self-balancing wheelchair, connected to a wheelchair base by a pair of leverages is disclosed. Each of the leverages is connected by a proximal lever, to a shared gear driven by a gearmotor assembly that in turn is keyed, or constrained, to one of the leverages. Each proximal lever is articulated to a distal lever and each distal lever is connected by a guide to the base of the wheelchair and has a supporting foot to be supported on the ground. The shared gear has a pair of cogwheels meshing with one another and each of the cogwheels is integral to a proximal lever of the couple of leverages and has its own rotation axis, so that the operation of the gearmotor assembly puts the pair of cogwheels in simultaneous rotation to drive the leverages up or down.

A wheelchair system may include vehicles including docking systems for a wheelchair. The wheelchair and the docking system may be coupled to controllers in communication with one another via a secure communication channel. A user may use a computing device to send signals to and receive signals from the controllers and a data processing system to select the docking system to which the wheelchair may be secured.

A vehicle includes: a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame; a lift unit to raise and lower the seat between a low position and a high position; a first leg extending downward from the seat and provided with a roller at a lower end thereof; a second leg extending downward from the seat, provided with a contact member at a lower end thereof, and displaceable in an up-down direction; and a lever connected to the second leg via a transmission mechanism. When the seat is in the low position, the contact member is displaced between a use position in which the contact member contacts the floor surface and a retracted position in which the contact member is separated from the floor surface depending on a position of the lever.
