Abstract
A passenger carrier frame of the invention includes a lower frame member, a folding frame member, a back frame member and a frame folding control. These frame members are pivotally connected adjacent their ends to form a triangular arrangement in side view. The pivotal connections permit the frame to be folded and the frame folding control acts at a selected one of the pivotal connections to drive and lock pivotal rotation at that pivotal connection.
