Make sure buckles and other hardware not worn out or broken, are without frays and cuts, webbing ok, in good condition so that one can be too :

Make it snug, should not cross neck and face (too high up for bodily protection) or under arm across ribs. Must feel comfortable (but no excuse not to even if feel otherwise) and firm

Lap(+shoulder) belts sould not be over abdomen but over pelvic bone.

All compartments & (high back) seats (anchored strongly) in vehicle should collectively cushion ie absorb energy in the event of, choy choy, accident

A harness, through which one slips one's legs, & to which is attached a steel reel that is secured to an anchor in the building.
