A truck seat suspension with scissors linkages. Each channel -in- channel scissor arm has a first C-section channel member opening in a first lateral direction, a second C- section channel member opening in the opposite lateral direction, the second C-section channel nesting within the first C-section channel member to provide abutting double flanges at the top and bottom of each scissor arm, and the first and second C-section channels welded to each other adjacent the abutting flanges. Enhanced bending stiffness, torsional properties, lateral stability and mass reduction are obtained compared to solid plate scissor arms. |
