Adjustable Back Angle Controller

(ABAC)

---

The basic design of this project consists of a lever handle that controls a circuit which powers a mechanical actuator attached to the back of a bed to adjust the angle. The key features to this device are its safety lock to prevent accidental movement, the control lever which increases the speed with the amount of force applied to it, and the intuitive approach to operating the handle such that lifting the handle will give the sensation of lifting the back angle upwards and visa versa. The device as a whole will accommodates a wide range of patients and users of all disabilities to easily adjust the back angle of any bed.
