  • Reconfigurable tilt wheelchair
    Patent number: 8579315
    Abstract: A modular wheelchair assembly is adapted to be reconfigured between a fixed angle of tilt, a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's knees and a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's center of gravity. The reconfiguration is achieved by modifying a limited number of selectively removable components of the support assembly or the pivot assembly of the wheelchair.

  • Telescoping crossbar assembly
    Patent number: 8424896
    Abstract: A telescoping crossbar assembly for a wheelchair comprises an inner tube that is slidable within an outer tube. The head portion of a pass-through fastener bears on the inner tube through a sufficiently large head-side aperture so as to slightly deform the inner tube and to hold the two tubes by friction in mutual engagement.
