Embodiments herein are directed to a wheelchair system that includes a wheelchair. The wheelchair includes a coupling mechanism, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium includes one or more programming instructions that, when executed, cause the processing device to determine the location of an accessory, position the wheelchair with respect to the accessory, and couple the wheelchair to the accessory via the coupling mechanism. The positioning of the wheelchair is independent from a user physically controlling the positioning of the wheelchair with respect to the accessory.

The present application relates to a cable tension adjuster for a manually operated, height-adjustable wheeled vehicle. The vehicle includes a brake assembly including a brake cable assembly and a brake cable housing shaped to enclose an excess portion of the brake cable assembly. The brake assembly includes a cable adjuster coupled to the brake cable assembly, where the cable adjuster is enclosed by the brake cable housing. The brake cable housing provides an access port to access the cable tension adjuster.

Disclosed is a wheelchair, and particularly to a wheelchair with a lifting function, which has a simple structure for automatically moving a seating block where a wheelchair user is sitting, and enables the seating block to have a lifting movement and a rotational movement, thereby simplifying a structure and assisting the wheelchair user in standing up safely

A view redirecting system for use on a mobility device to redirect a user's view to a more favorable orientation is disclosed. One embodiment includes a first structure having a convex first reflective surface, a second structure having a flat second reflective surface and a third structure. The third structure being an adjustable structure and configured for connecting said first and second structures together. The first structure and the second structure are configured to be positioned such that the first reflective surface and the second reflective surface are facing each other at angle up to and including ninety degrees. The third structure configured to maintain the angle. The system is arranged to redirect a user's view from a first line-of-sight to a second line-of-sight by light interacting with the reflective surfaces The system being configured for attachment to a structural member of the mobility device.

A backrest for a wheelchair or other mobility device configured to provide user controllable cooling and heat to the wheelchair user's back. The cooling element includes a Peltier chip, heat sink and gel pad for user contact. The heating element includes heating wire interposed between the fabric cover and the compressible foam of the backrest cushioning. The cooling element and heating element both move with the movement of the fabric cover so as to provide good heat conduction contact without adversely affecting cushioning. The backrest includes a tillable mount.

A wheelchair comprises a base assembly and a tilt assembly supported on the base assembly. The base assembly has a wheelbase and a wheel track. Each of the wheelbase and wheel track is independently adjustable. The tilt assembly is unchanged when either the wheelbase or wheel track is adjusted.

A human-powered wheelchair for use on land and in water that comprises flotation and propulsion means. The wheelchair can be propelled by the operator on land in a manner similar to a typical wheelchair. The wheelchair can be propelled in the water by propellers that are mechanically and rotationally coupled to the side wheels of the wheelchair.

A wheelchair is provided. First supports for supporting a user of the wheelchair are unevenly disposed to form a perimeter, and second supports for supporting the user of the wheelchair are unevenly disposed at least partially within the perimeter of the first supports. The first supports support the user when the first supports are in a raised position and the second supports are in a lowered position. The second supports support the user when the second supports are in a raised position and the first supports are in a lowered position. A alternation of supporting the user with the first supports or the second supports facilitates reduction of pressure sores of the user. In various embodiments, multiple groups of supports are used, the supports contour to a user's anatomy and/or the supports are pneumatic.
