more than needed. The seat belts pro-
vide maximum protection in a frontal

you are reclined, the lap belt may
slide past your hips and apply re-
straint forces directly to the abdomen
or your neck may contact the shoul-
der belt. In the event of a frontal
collision, the more the seat is re-
clined, the greater the risk of death
or personal injury.
