Somewhat more restrained

Instead of a full circle with the extra bar in the back to attach to her steel waist belt, this one just curves around and attaches directly to her waist belt.   The effect is the same.  The curved bar with her wrists shackled to a sliding ring on it, is held out in front of her body, preventing her from reaching herself.  

This version also has a few strategically placed holes in the bar, through which padlocks can be placed to limit the movement of the rings or to which more chains can be directly attached, as they are here.  

In this configuration she cannot reach her mouth, but can crawl on her knees to do limited chores, or lay down, but may find it tough to get back up.   Sitting is not an option.   Judging by the expression on her face, she finds this one a little less amusing than the last.
