Abstract
Disclosed herein is a stand-up unit having a parallelogram and a hinged lever that is coupled to the parallelogram and to the seat such that the seat is disposed at an angle in relation to the seat as the parallelogram moves toward the standing position. Disclosed also are wheelchairs, therapy chairs, and other devices or apparatuses that can incorporate the stand-in unit for purposes of assisting a user in moving from a sitting to a standing position.
