Abstract

A grab rail assembly for a vehicle includes a base element, a handle, a pivot pin, a cantilevered spring, and a fastener. The base element is engageable with a structural portion of the vehicle. The pivot pin is operatively connected to the handle for pivotally connecting the handle to the base element. Further, the cantilevered spring has a flat leg portion for bearing against flat surfaces of the pivot pin in order to maintain the handle in either a stowed position or an extended position. Furthermore, a fastener is provided for fixing the cantilevered spring and the base element to the structural portion of the vehicle. The pivot pin may also support a hook on which coats and other articles may be hung. The hook is pivotally supported by the pivot pin such that the hook may be positioned in one of a plurality of discrete positions by a detent mechanism.
