| 摘要 |
The present invention provides a foldable and preferably non-motorized wheelchair, which has an X-shaped cross-bracing frame assembly that folds or scissors to allow the side frames of the wheelchairs to be moved between a spaced-apart deployed position for use and a folded position for storage or transport. The invention addresses the problem of splaying or tilting of the side frames during folding, which is the result of the geometry of the articulation provided by a link element that pivotally connects the side frames with cross-struts of the cross-bracing frame assembly. |
