Morphology

headrail = head + rail (transparent) = head + rail

The compound denotes a rail located at the 'head' (top) of a blind or curtain, a meaning readily inferable from its parts.

Etymology

Headrail comes from head meaning 'top' and rail meaning 'bar' or 'track', so it is literally the bar at the top of a window. That's why a headrail is the horizontal bar from which blinds or curtains hang and move.
