Abstract

In accordance with the present invention, a vehicle cargo restraint system comprises a cargo restraining strap and at least two tie down rings proximate the perimeter of the cargo area, positioned approximately opposite each other. In trucks and trailers, additional tie down rings may be conveniently placed near the top of the vertical corners of the cargo bed. At least one of each pair of the tie down rings is configured to allow a cargo restraining strap to be passed through it and be attached to a mechanical tightener, e.g., a ratchet, which is located conveniently on a wall of the cargo area, at a distance from the pass-through, tie down ring. The mechanical tightener may be rotatably and removably attached to the wall of the cargo area. The cargo restraining strap, both of the tie down rings and the mechanical tightener, and their respective anchoring sites, must all be strong enough to restrain cargo under predetermined conditions of cargo weight, vehicle speed and type of accident.

Dependent claims

For a vehicle having a cargo area, said cargo area having:

at least one wall, said wall having at least one conveniently located, tie down docking port;
said docking port having an aperture configured to be engaged to a protruding, complementary docking mechanism to secure said docking mechanism to said docking port without the need of a nut(s) or a bolt(s), and a floor, said floor having a perimeter, a cargo restraint system comprising:
a cargo restraining means having a first end, an intermediate portion for engaging cargo, and a second end;
at least one first tie down means disposed proximate said perimeter of said floor;
at least one second, pass-through, tie down means disposed proximate said perimeter of said floor, approximately opposite said at least one first tie down means;
and at least one third tie down means having a protruding, complementary docking mechanism configured to be inserted into said aperture to allow said docking mechanism to be easily and quickly engaged to and disengaged from said at least one conveniently located, tie down docking port,
whereby cargo may be restrained against the floor of the cargo area by attaching said first end of said cargo restraining means to said at least one first tie down means, engaging cargo with said intermediate portion of said cargo restraining means,
threading said second end of said cargo restraining means through said at least one second, pass-through, tie down means, and securing said second end of said cargo restraining means to said at least one third tie down means which has been engaged to said at least one conveniently located, tie down docking port.

5 more elements

For a vehicle having a cargo area, said cargo area having a floor and at least three walls including a first wall, a second wall and a third wall;

said second wall having a width;
said third wall having at least one conveniently located, tie down docking port;
said first wall and said third wall being approximately opposite and parallel to each other;
said first wall and said third wall being separated by the width of said second wall such that said first wall and said second wall converge at a first vertical corner, and said second wall and said third wall converge at a second vertical corner;
said first vertical corner and said second vertical corner each having a top and a bottom;
a cargo restraint system comprising:
a cargo restraining means having a first end, an intermediate portion for engaging cargo and a second end;
at least one first tie down means conveniently disposed proximate the top of said first vertical corner;
at least one second, pass-through, tie down means conveniently disposed proximate the top of said second vertical corner approximately opposite said at least one first tie down means;
and at least one third tie down means having a docking mechanism to allow it to be easily engaged to and disengaged from said at least one conveniently located, tie down docking port,
whereby cargo may be restrained against said second wall by attaching said first end of said cargo restraining means to said at least one first tie down means, engaging cargo with said intermediate portion of said cargo restraining means, threading said second end of said cargo restraining means through said at least one second, pass-through, tie down means, and securing said second end of said cargo restraining means to said at least one third tie down means which has been connected to said at least one conveniently located, tie down docking port.
