ABSTRACT:
An anti-rollback assembly adapted or adaptable for use in combination with a wheelchair. The anti-rollback assembly includes a one-way brake assembly automatically immobilizing the wheelchair against rearward movement when the occupant attempts to rise from or sit in a seat member of the wheelchair, yet at the same time does not prevent the wheelchair from moving in a forward direction. Conversely, when the occupant is fully seated in the seat member, the one-way brake assembly is disengaged so that the wheelchair can move freely in forward or rearward directions. The assembly can be retrofitted onto existing wheelchairs, and is adjustable to fit various size wheelchairs.
