There is a bar or some device that is there to prevent your stuff from sliding forwards. I’ve not been crawling on the airplane floors enough to see any weight rating on it but I would bet money on it being crash tested and rated according to whatever the overhead compartments are.
The overhead compartments have a weight limit because they must be designed to keep the stuff in there during an emergency.
No weight limit under the seat, though.
