In a crash you could go into it,receiving neck or other injuries.The lap belt can’t do its job either. In a crashthe belt could go up over your abdomen. Thebelt forces would be there, not at your pelvicbones. This could cause serious internalinjuries.For proper protection when the vehicle is inmotion, have the seatback upright. Then sitwell back in the seat and wear your safety beltproperly.Head restraints are fixed on some models andadjustable on others. Slide an adjustable head restraintup or down so that the top of the restraint is closestto the top of your head. This position reduces thechance of a neck injury in a crash.1-7
