Publication number: 20240074925Abstract: A motorization device for a wheelchair may have a positioning arm adapted to be connected to a frame of the wheelchair by at least one lockable joint. A motor block may be operatively connected to the positioning arm by at least one other lockable joint, the motor block including at least a motor and an output roller operatively coupled to the motor, the output roller configured to contact a wheel of the wheelchair to impart torque to the wheel. The positioning arm and the motor block collaborate to provide the motor block with an engaged configuration in which the motor block is configured to biasingly contact a wheel of the wheelchair, and a disengaged configuration in which the motor block is separated from the wheel of the wheelchair.Type: ApplicationFiled: January 14, 2022Publication date: March 7, 2024Inventors: Gabriel FERON, Alexandre BLEAU, Camille GUILBAULT, Alexandre STEFANI, Mikael PROUS, Benjamin PALMER, Alain CHEVIGNY, Pier Alexandre ETHIER

Patent number: 11021013Abstract: A system of bracket assemblies for a wheelchair comprises a pair of bracket assemblies adapted to be connected to respective sides of a seat frame of the wheelchair. Each of the bracket assemblies has a base adapted to be secured to a seat frame member of the seat frame, an arm adapted to be secured to a backrest frame member of a backrest frame, and a pivot pivotally connecting the base to the arm for rotational movement of the arm relative to the base. One or more blocking mechanism blocks the rotational movement of the arm relative to the base in a use orientation of the backrest frame. A rod having opposed ends connected to the base of the pair of the bracket assemblies for spacing the bracket assemblies away from one another. A rear wheel unit is also provided.Type: GrantFiled: March 1, 2017Date of Patent: June 1, 2021Assignee: MOTION COMPOSITES INC.Inventors: Pierre-Andre Couture, Michael Archambault, Alexandre Bleau, Maxime Lamarre, Alec Stephani, David Gingras

Patent number: 11021014Abstract: A tube assembly for a wheelchair frame comprises a tubular member having at least a first portion and a second portion angled relative to the first portion, the first portion configured to be in a seating zone of the wheelchair frame. The second portion is configured to be in a bottom front zone of the wheelchair frame, the tubular member defining a surface concavity in its peripheral surface delimited by a peripheral step, the surface concavity located at a junction between the first portion and the second portion of the tubular member. An interface member has a peripheral contour shaped and sized for the interface member to be received in the surface concavity and contoured at least partially by the peripheral step.Type: GrantFiled: March 1, 2017Date of Patent: June 1, 2021Assignee: MOTION COMPOSITES INC.Inventors: Alexandre Bleau, Michael Archambault, Pierre-Andre Couture, Alec Stephani, Maxime Lamarre, David Gingras

Patent number: 10155414Abstract: A caster assembly for a wheelchair comprises a stem having a frame clamp at a first end and a fork clamp at a second end, the frame clamp configured to form a frame joint with at least one rotational degree of freedom with a frame portion of the wheelchair, a tightening of the frame clamp securing the stem to the frame portion, the frame joint having a frame rotational axis. A fork unit has a fork portion and a caster rotatably supported by the fork portion, the fork unit having swivel mechanism, and a joint portion forming a rotational joint with the fork clamp of the stem, a tightening of the fork clamp blocking rotation of the rotational joint, the rotational joint having a fork rotational axis. A vector of the fork rotational axis is normal to a fork rotational plane in which the fork rotates relative to the stem, and further wherein the frame rotational axis is not parallel to the fork rotational plane.Type: GrantFiled: March 1, 2017Date of Patent: December 18, 2018Assignee: MOTION COMPOSITES INC.Inventors: Alexandre Bleau, Michael Archambault, Pierre-Andre Couture, Alec Stephani, Maxime Lamarre, David Gingras
