Design Helps People Sit In and Stand Out of Wheelchairs
From: Medical Design Technology - 02/25/2015

Medical device manufacturers can license, develop, and manufacture a Purdue
University design by four graduates of Purdue's School of Mechanical
Engineering that incorporates an electric seat lift and integrated walker
that could help users more easily sit into and get out of a traditional
wheelchair.

The Wheelchair Access Assistant incorporates an electric seat lift and a
walker that are attached on a traditional, factory-manufactured wheelchair.
The seat lift is activated by pressing a button; the walker is deployed by
extending the wheelchair's armrests, locking a crossbar, and lowering scissor
legs to the ground and locking them.
