摘要： A pressurized breathing system enabling the execution of the Valsalva maneuver. A breathing mask has an inhalation valve and an exhalation valve. A Valsalva valve when in its normal position does not interfere with the regular performance of the system. When it is activated, it holds the exhalation valve closed. An exhalation effort of the wearer then accomplishes the Valsalva maneuver against the closed inhalation valve.

摘要： A helmet assembly (10) provided with either single or dual visor mechanisms (14, 16) and low profile right and left side pivot assembly (18, 20). A low profile visor actuating arm assembly (36, 38) is associated with each visor and the left hand pivot shaft (46) of the left side pivot assemblies (20). Each visor actuating arm assembly is capable of being readily manipulated by the left hand of a pilot so that the associated visor can be moved between fully raised and completely down positions, the visor actuating arm assembly also cooperating with the pivot shaft (46) to positively lock the visor in either of its fully raised or completely down positions. A pivot hub assembly (47) is also disclosed for securing the pivot shaft (46) to the helmet (12).
