From the pages of "Superboy and the Legion of Super-Heroes", Volume 1, Issue #207 (DC, March-April 1975) -- Light Lass gets karate-chop KOed, while Shrinking Violet is shown unconscious (the actual KO was, sadly, off-panel); but she looks really good getting tossed around by Superboy, who has been mind-controlled into ...
Here are some scenes from Avengers #120-122 (February-April 1974) -- the Scarlet Witch and Mantis are KOed, and Wanda eventually exacts KO revenge on the villainess Virgo!

Cavewoman is choked unconscious by another equally voluptuous woman. It looks like something Gytalf2000 commissioned :-)
There's also a great alternate cover from Budd Root, which looks like an unconscious Cavewoman (or just really tired).
This scene from the August 1974 issue of the Avengers is a "gotcha" cover, since the Scarlet Witch was not KOed in the actual story. But she looks great in that unconscious pose in the Vision's arms!

The Scarlet Witch is felled by an energy discharge as she comes to the aid of the Vision. The Kree's Sentry captures her, and places her in bondage. a nice scene from the early 1970s!

From a recent European comic. The cover shows a woman being dragged by her hair.
The story starts with a girl waking up in a big spider's lair. The girl is bound with the sticky webbing.
Supposedly she was KO'd in the previous issue by the bug, but we don't see it.
A girl who uses a scythe as a weapon, gets in a fight with a girl who has magic powers. Scythe girl gets tied up in ribbons that appeared out of thin air.
The cover has really sexy art!
A girl has a little too much to drink at a bar and has to be carried home. The guy lays the sleeping girl on a bed, and awkwardly tries to make love with her.
