Abstract
A foldable frame (10) for a lightweight wheelchair (8) is disclosed. The foldable wheelchair frame (10) includes a pair of side frame assemblies (12, 14) each having a substantially horizontally oriented upper side frame member (16) extending for directly supporting a seat assembly (20). A cross bracing assembly (38) is mounted between the side frame assemblies (12, 14) for movement of the side frame assemblies (12, 14) between a deployed position and a collapsed position. The cross bracing assembly (38) includes a pair of cross bracing members (40, 42) pivotally coupled to each other by a pivot (44). The cross bracing members (40, 42) are pivotably coupled to the side frame assemblies (12, 14) by coupling proximate upper ends to the upper side frame members (16) and proximate lower ends to a remainder of the side frame assemblies (12, 14). At least one of the cross bracing members (40, 42) is formed for cooperative interengagement with one of the upper side frame members (16 ) and a pivot assembly (46) to secure the cross bracing members (40, 42) in a weight supporting position in the deployed condition.
