DESIGN PROCESS OF SESURA
initial concepts
how the internal gears work
The internally housed gears adjust the depth of the backrest depth by turning the handle on the left side of the chair.
It consists of a few components, a rack and pinion + worm drive gear and a turn handle. By using the turn handle you are translating the rotational motion to linear motion.
Using this compact system allows the gears to be housed internally yet allow the musician to simply adjust the backrest to their preferred depth with just one hand.
