Abstract: A seating assembly includes a seat having a shell, at least two harness straps each having upper portions, and an adjustment mechanism for adjusting the upper portions of each of the harness straps. The adjustment mechanism includes a support member and at least one biasing member. The biasing member exerts a biasing force upon the support member in an upwards direction to adjust the upper portions of the harness straps. The seating assembly also includes first adjuster strap and a first web adjuster, where the harness straps are connected to the first adjuster strap, and the first adjuster strap is selectively secured by the first web adjuster. The seating assembly also includes a second adjuster strap and a second web adjuster. The second adjuster strap is fixedly attached to the seat and wound around the support member, where the second adjuster strap is selectively secured by the second web adjuster.
