MANUAL WINDOW SHADES
These window shades are designed to match the window configuration and allow each passenger to manually adjust the light diffracting or light blockage of the window.
They can be of different types:
1. Roll up type
Fully light blocking shade material, rolling up onto a spool located above the window.
Used when a rigid window shade cannot be used for space reasons likeescape hatch windows. Other applications include maritime patrol aircraft windows, military aircraft, etc.
2. Pleated fabric window shades
Double pleated fabric which collapses either above or below the window.
When operated shade material can be light diffracting, or light blocking. Passengers can move the rail up and down directly or by operating a handle.
