Reclining-Chair Mechanism

Reclining-Chair Mechanism

      This is an exercise in mechanical engineering to design a reclining chair so that the chair could recline without bumping the wall, later known as a wall hugger.




      This was Steve Hines’ first paid consulting project, done in 1966 for the industrial designer, Walter P. Baerman, who was also head of the Industrial Design department at North Carolina State University in Raleigh.

      Like many mechanisms at the time, this started as cardboard cutouts pinned to a board with thumb tacks.  When experimenting, I found that the midpoint of the backrest moved in an arc.  By attaching a link at that point, when the bottom was slid horizontally out from the wall, the top of the backrest dropped down at a uniform distance from the wall.
