Abstract: A clutch assembly includes an inner hub, an outer hub, a roller bearing, and a control collar. The inner hub includes a cam surface having a peak and a bottom. The roller bearing is interposed between the inner and outer hub and coupled to the inner hub at a predetermined position relative to the peak. In a locked position, the roller bearing is proximate the peak, wherein rotation of the inner hub relative to the outer hub is inhibited in a locked direction. In the unlocked position, the roller bearing is disposed a greater distance from the peak relative to the locked position, wherein rotation of the inner hub relative to the outer hub is not inhibited in the locked direction.

Abstract: Methods and systems are provided for an armboard adjustment assembly for a patient support table. In one embodiment, an armboard adjustment assembly is configured to retain a rotational position of an armboard of a patient support table via a plurality of one-way clutches, and in another embodiment the armboard adjustment assembly is configured to retain the rotational position of the armboard via a pair of friction pads. In this way, the armboard may be moved into a continuous plurality of positions between a fully lowered position and a fully raised position.
