Patent number: 8579315Abstract: 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.Type: GrantFiled: November 9, 2012Date of Patent: November 12, 2013Assignee: PDG Product Design Group Inc.Inventors: Nancy Balcom, Louis Belanger, Torr Brown, Janusz Krawczynski, Phil Mundy, David Harding, David Cheng

Patent number: 8424896Abstract: 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.Type: GrantFiled: January 6, 2012Date of Patent: April 23, 2013Assignee: PDG Product Design Group Inc.Inventors: Nancy Balcom, Louis Belanger, Torr Brown, Janusz Krawczynski, Phil Mundy, David Harding, David Cheng Cheng

Patent number: 6447064Abstract: A wheelchair with a tiltable seat locates the tilt fulcrum between 3 and 7 inches from the front edge of the seat pan and between 1 and 4 inches below the surface of the seat pan. This minimizes the elevation of the rider's knees when in a tilted position, and allows for more stability and a shorter wheel base. Manual self-tilting is facilitated by a gas strut arrangement disposed on brackets below the seat pan, and operated by a rider-controlled valve.Type: GrantFiled: June 20, 2000Date of Patent: September 10, 2002Assignee: PDG, Inc.Inventors: Phil Mundy, Matt Delorme, Nancy Balcom
