Reclining-Chair Mechanism
Reclining-Chair Mechanism
This is a mechanical engineering assignment to design a chair that can be recline without bumping the wall, later known as a wall hugger.
This was Steve Hines’ first paid consulting project, done in 1966 for Walter P. Baerman, 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. 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 straight down at a uniform distance from the wall.
HinesLab currently offers consulting in the area of industrial design, and a variety of licensable technology.
