cam lock/latch lock
cam lock belts are very very convenient, but ive always been afraid something could bump it in a wreck. my only bad experience was when I landed upside down and was wearing a latch lock style harness. it held good but with any belt, with your body weight hanging upside down on the shoulder straps, its hard to get it unlocked. but in that kind of situation, strength comes with the adreneline to get the he** out of the car in case something else may happen. since then ive just stuck with the latch style lock belts
