ABSTRACT:
A bell assembly is shown for adjusting the height of a chair base. The bell assembly is threaded onto a support post slidably located in a hub and the bell assembly is turned to regulate the height of the support post relative to the hub. The bell assembly includes a spring retaining clip for engagement with the hub to prevent axial separation of the support post and the hub when the chair is lifted. The spring retaining clip includes a C-shaped base portion which engages a bell nut in the bell assembly to prevent longitudinal movement of the retaining clip relative to the bell assembly. The bell assembly also includes a bell housing having a wall portion located adjacent to the retaining clip base portion to prevent rotational movement thereof and disengagement of the retaining clip and bell nut.
