Securement system for a rollable mobility aid

A securement system is provided for a rollable mobility aid with a frame and rollers, which aid is located adjacent surrounding structure such as the interior of a vehicle. The system includes protruding structure attached to such frame, with a substantially rigid, operative section that includes a broad engaging expanse. Also included is upright receiver (or capture) structure fixedly attached to such vehicle in a receiving position, and including a receiving section that is correspondingly broad with respect to the engaging expanse. The receiving section further includes a selectively actuable securement/release mechanism for securing the operative section to the vehicle. The protruding structure is shown as plural spaced members, with the receiver structure being constructed with receiving sections to receive each member. The receiver structure is shown as capable of selective rotation about its vertical axis and selective translation with respect to its receiving position. The system is also shown with indicator structure operatively connected to the securement/release mechanism and structured to provide an indication of whether a securement condition exists. Plural types of actuators for the securement/release mechanism are also provided.
