Instead, it will be in front of you. In a crash you could go into it, receiving neckor otherinjuries. The lapbelt can't do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, notat your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright.
