Forget all the glue and trying to re-attach weak plastic to the weak plastic seat bracket. Take two, flat washers (metal) that will cover the seat bracket area, keeping the detached plastic rings, if still intact, and re-attach the bolts through the toilet and voila. You now have a much sturdier attachment in place and you don't have to worry about whether glued plastic can hold up.

Me thinks me posted too soon ...

The Cover of the seat does NOT go back far enough, unless the washers are really thin, and perhaps made of a thinner plastic as well. The metal flat washers DO hold the seat down nicely, but with that cover not going back far enough, that poses a new problem. I'm still working on a better solution..
