Head Restraints Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their job when you're reclined like this. The shoulder belt can't doits job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can't do its jobeither. In a crash the belt could go up over your abdomen. The belt forces would bethere, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle in is motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly. Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance o a neck injury in a crash. f 1-6
