摘要：
A wheelchair lift (20) for a vehicle is disclosed. The wheelchair lift includes a lift platform (22) coupled to a support structure (32) by an attachment assembly (74). The lift platform is reciprocal between a stowed position and an extended position, wherein the lift platform is coplanar with a first plane. The wheelchair lift also includes a redundant support assembly (80) in communication with the lift platform to provide secondary support of the lift platform when the lift platform is in the extended position and to maintain the lift platform in a second plane substantially parallel to the first plane if a portion of the attachment assembly fails.
