Foldable wheelchair

摘要

A foldable wheelchair includes two side frames, each having a front wheel and a rear wheel mounted thereon, and a scissor-type element arranged between the side frames and having two scissor-type arms that are mounted pivotably in the side frames in one scissor-type element end. The scissor-type arms are mounted pivotably in another scissor-type element end in manually actuable actuating members that are mounted pivotably to the side frames at a distance from the pivot axis of the other scissor-type element end. A folding hinge is mounted pivotably in the side frames and is arranged at a distance from the other scissor-type element end. An actuating means is connected pivotably to the folding hinge at a distance from the side frames and is effective between the folding hinge and one of the actuating members at a distance from the pivot axis of the actuating member in the associated side frame. Means are provided for fixing at least one actuating member relative to the associated side frame in the unfolded position of the wheelchair.
