摘要：The article deals with the issues of operating wheelchairs with manual drive in areas with a significant inclination angle. The kinematics of a wheelchair while climbing a hill was analyzed. On the basis of the conclusions drawn from the research, two solutions for systems that block the reversal of a wheelchair on a hill have been proposed. Among the solutions mentioned, a mechanical anti-rollback system with three operating modes and an electric anti-rollback system is described. The described electric anti-rollback system is part of a manual-electric hybrid drive unit to the manual wheelchairs.
