Abstract: An improvement is provided in a bed having a side rail framework, and at least one dual-position rail assembly which is secured on one side of the bed. The improvement includes a rotatable structure upon which the dual-position rail assembly, is mounted in order to enable the dual-position rail assembly to move between two positively-stopped and automatically locked positions. A first of such positively-stopped and automatically locked positions disposes the dual-position rail assembly in an assist, vertically-oriented, position which is perpendicular to the longitudinal axis of the bed. A second of such positively-stopped and automatically locked positions disposes the dual-position rail assembly in a guard, horizontally-oriented, position which is parallel to the longitudinal axis of the bed.
