Abstract
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.
Claims4
A vehicle seat suspension with scissors linkages, each scissor having a pair of crossing scissor arms, each scissor arm comprising a first C-section channel member having its channel opening extending in a first lateral direction, a second C-section channel member having its channel opening extending in the opposite lateral direction, the second C-section channel member being positioned within the lateral opening of the first C-section channel member to provide a channel-in-channel scissor arm, and the first and second C-section channel members being welded to one another at positions along the scissor arm;
- whereby each scissor arm provides enhanced bending stiffness and torsional properties, enhanced lateral stability, and mass reduction.
