Child safety seats generally require a second tiedown in addition to the
seat belt. Basically, the stock belt just holds the bottom of the seat DOWN,
and a strap ties the top of the seat to the frame of the vehicle behind it
to keep the seat from flipping FORWARD.
If it were me, I'd probably make my own out of one of the rock climbing
"hangers" I have left over from my reckless youth. <

Bolt one or two through the frame somewhere solid, they're not going
anywhere.
