Axion Rotary Interface
- The Axion enables headrest
pads and head positioning
devices to rotate with the user’s head, thus
transforming static headrests into dynamic
positioning devices.
- Combined with the
user’s head support, the Axion allows the
head support to rotate to reduce shear forces
and improve peripheral vision.
- Head
support that also enables the head to move horizontally.
