Side rail of a flatbed trailer for use with cargo restraint devices

1. A floor assembly of a vehicle, for example, comprising:

a plurality of transversely-extending cross members;

a plurality of longitudinally-extending floor planks positioned above and coupled to a top surface of the plurality of cross members; and

a support member configured to extend generally along a length of the floor assembly, the support member including a top wall generally flush with the plurality of longitudinally-extending floor planks, and a vertical wall coupled to the top wall and extending downwardly therefrom such that a bottom end of the vertical wall is positioned generally below the cross members,

wherein the support member is positioned between two of the longitudinally-extending floor planks, and

wherein the top wall of the support member includes a channel formed therein which extends along a length of the support member, the channel being configured to receive a cargo restraint device therein.

2. The floor assembly of claim 1 , wherein the channel is generally J-shaped when viewed in cross-section.

3. The floor assembly of claim 1 , wherein the channel formed in the top wall is defined by spaced-apart vertical members and a base member coupled to the bottom of the vertical members, wherein the base member is wider than a widest portion of the channel.

4. The floor assembly of claim 3 , wherein the base member is welded to one of the cross-members of the floor assembly.

5. The floor assembly of claim 3 , wherein one of the vertical members defines a width greater than another one of the vertical members.

6. The floor assembly of claim 3 , wherein the vertical members are first and second vertical members and wherein the top wall further includes third and fourth vertical members which are each spaced-apart from the first and second vertical members.

7. The floor assembly of claim 1 , further comprising a side rail spaced-apart from the support member and including a top wall defining a side rail channel and an aperture spaced-apart from the side rail channel, wherein the side rail channel is configured to receive the cargo restraint device therein, and wherein the aperture is configured to receive a different cargo-restraint device therein.

8. The floor assembly of claim 7 , wherein the side rail is positioned outwardly from the transversely-extending cross-members of the floor assembly, and wherein the channel of the side rail is positioned outside a lateral end of at least one of the transversely-extending cross-members of the floor assembly.

9. The floor assembly of claim 1 , wherein the channel is positioned laterally outside the vertical wall of the support member away from a longitudinal centerline axis of the floor assembly.

10. The floor assembly of claim 1 , wherein the support member is positioned laterally outside a longitudinal axis of the floor assembly.

11. The floor assembly of claim 10 , wherein the support member is a first support member, and further comprising a second support member spaced-apart from the first support member and coupled to the first support member by a cross-brace, and wherein the second support member includes a channel formed in a top wall of the second support member which extends along a length of the second support member and is configured to receive the cargo restraint device therein.

12. The floor assembly of claim 1 , further comprising a cross-brace coupled directly to the support member and configured to extend transversely across a central portion of the floor assembly, wherein at least a portion of the cross-brace is positioned below the plurality of transversely-extending cross-members.
