What is the correct positioning of the chest or diagonal strap of the seatbelt?

Question

DentroTest · Accepted Answer

For the seatbelt to perform its restraining function effectively and avoid serious injuries in the event of an impact or sudden braking, its straps must be placed precisely over sturdy bony parts of the body: The chest or diagonal strap must cross the collarbone, exactly at the midpoint between the shoulder and the neck, and run diagonally down the center of the chest (sternum). If it sits on the neck, it could cause strangulation or serious cuts in the event of a collision; if it sits too far toward the shoulder, the occupant could slip out of the belt. The abdominal or pelvic strap is the one that must cross the hip bones (pelvis), below the abdomen, and must never sit over the soft abdomen, since undue pressure in that area would damage vital internal organs. Therefore, resting the chest strap on the iliac crests and the lower abdomen is confusing it with the abdominal strap.
