1. A personal restraint system for use in moving vehicles for securing occupants while at the same time allowing limited movement of the occupant, comprising:
a pole affixed to the deck and ceiling of the vehicle interior; a base assembly, attached to the lower half of the pole; a upper assembly, attached at or near the midpoint of the pole; a retractor attached to said base assembly, with webbing deployed parallel to said pole and fed through a webbing guide or router attached to said upper assembly; said webbing having an end fitting that permits the clipping of a carabiner or other removable attachment mechanism to permit the webbing to be attached to the rear of a harness; said pole being affixed to the vehicle using flanges made of steel, aluminum, or other material of sufficient strength; said base assembly being constructed by using at least two strut-type channels attached to said pole, said strut channels being attached to said pole using a minimum of one set of pipe clamps per strut of size appropriate to match the diameter of said pole, said strut channels being connected to each other at their face using a two-holed metal bracket with holes large enough to admit bolts of minimum grade 5 strength, the topmost bolt which shall be used to affix said retractor in a vertical position; said base assembly being further bound to said pole by the use of a single U-bolt, installed in between said channels and fastened using a metal plate running across the face of said two-holed metal bracket; said base assembly being further affixed to said pole by the use of a minimum of two shaft collars, which shall be attached immediately above said base assembly so as to prevent upward axial slippage of said base assembly along the pole; said upper assembly being constructed by using at least three strut-type channels attached to said pole, said strut channels being attached to said pole using a minimum of one set of pipe clamps per strut of size appropriate to match the diameter of said pole, said strut channels being connected to each other at their face using a four-holed metal bracket with holes large enough to admit bolts of minimum grade 5 strength, the bottommost bolt which shall be used to affix said webbing guide in a vertical position, said upper assembly being further bound to said pole by the use of a minimum of two U-bolts, installed in between each of said channels and fastened using a metal plate running across the face of said four-holed metal bracket; said upper assembly being further affixed to said pole by the use of a minimum of one shaft collar, which shall be attached immediately below said upper assembly so as to prevent downward axial slippage of said upper assembly along the pole; and said assembly in its entirety, when attached to an occupant wearing a harness, permits the limited movement of the occupant but restricts the movement in the event of a rapid deployment of webbing, thereby restricting uncontrolled movement of the occupant within the vehicle. |
