Abstract

A variable output torque rod system for panel counterbalance includes a telescoping torque rod having a solid inner rod with a first end concentrically disposed in a tubular outer rod, wherein the tubular outer rod includes a first end fixed relative to a storage area, and wherein the solid inner rod includes a second end secured in a slider block relative to the panel. The telescoping torque rod is configured to store energy by being twisted when the panel is pivoted in a first direction relative to the storage area, and wherein the slider block is operative to adjust an overall length and cross-sectional area of the telescoping torque rod when the slider block is moved from a fully extended position to at least one other position that is less than the fully extended position.
