11. The restraint harness of claim 9 , wherein the torso strap includes elastic material biasing the torso strap to a shortened length, and non-elastic material defining a maximum length of the torso strap.
12. A sheath assembly for connection with an occupant restraint harness of a vehicle, the sheath assembly comprising:
a torso sheath configured to receive a pair of shoulder belts of the restraint harness, the torso sheath including a sheath body defining an interior cavity and padding positioned within the interior cavity, the sheath body including a neck contour having a predetermined length and a pair of arms each having a first end attached to opposite ends of the neck contour and extending therefrom in a direction parallel to each other to a second end, and
a number of waist sheaths configured to receive a lap belt of the restraint harness,
wherein the sheath body includes an outer cover overlapping a front side of the sheath body to define a closure between the sheath body and the outer layer, the closure having a pair of first openings disposed at the opposite ends of the neck contour and a pair of second openings each disposed proximate to the second ends of different ones of the arms, the pair of first openings defining a maximum distance therebetween.
13. The restraint harness of claim 12 , wherein the sheath body is U-shaped and the neck contour is adapted for contact with the occupant's neck.
14. The restraint harness of claim 12 , wherein the number of waist sheaths each include a sheath body that defines an interior cavity and padding positioned within the interior cavity.
15. The restraint harness of claim 14 , wherein the number of waist sheaths each have a length defined between an inner end and an outer end, the inner ends each of the number of waist sheath being configured for overlapping engagement with each other, and a height of each of the number of waist sheaths is tapered proximate to the inner and outer ends.
16. The restraint harness of claim 12 , further comprising a torso strap connected at opposite ends thereof to each of the arms for securing the occupant's torso, the torso strap includes a buckle positioned between the opposite ends thereof.
17. The restraint harness of claim 12 , wherein the maximum distance is a distance defined between outer portions of the first openings.
18. A restraint system for securing an occupant within a vehicle, the restraint harness comprising:
an occupant seat having at least one opening defined therethrough proximate to the occupant's neck,
