1. An adjustable breath guard, comprising:
a frame;
a shield; and
a hinge assembly pivotally coupling the shield to the frame, the hinge assembly comprising:
a base coupled to one of the frame or the shield;
a body coupled to the other of the frame or the shield and pivotally coupled to the base, the body defining a ratchet protrusion;
a pawl pivotally coupled to the base and repositionable between an extended position and a retracted position; and
a pawl retracting plate that is pivotally coupled to the base and repositionable between (a) a first position in which the pawl retracting plate engages the pawl and retains the pawl in the retracted position and (b) a second position in which the pawl retracting plate permits the pawl to move to the extended position,
wherein the pawl is configured to engage the ratchet protrusion to limit rotation of the body relative to the base in a first rotational direction when the pawl is in the extended position, and wherein the pawl is separated from the ratchet protrusion in the retracted position such that the pawl permits rotation of the body in the first rotational direction.
