Protective headgear equipment with respirator and optical shield

A head protective equipment comprising:

• a breathing mask connectable to a breathing-gas source and adapted to be applied, in a use position, around a user's nose and mouth, for supplying said user with breathing gas;
• an eye protective shield adapted to be applied around the user's eyes;
• and
• first and second lock elements, respectively, located on said mask and on said shield, and adapted to cooperate with each other in order to secure said shield to said mask when said mask is in said use position around said user's nose and mouth, said first and second elements being adapted to engage and interlock with each other to create a snap-together connection,
• said shield and said mask being adapted to be locked together by a two-step movement, the first step comprising approaching the shield to the mask until said shield reaches said mask, and the second step comprising a substantially linear movement of bringing said shield closer to said user's nose until locking,
• wherein said shield comprises a grasping unit around said second lock element, said grasping unit comprising two substantially vertical surfaces and one substantially horizontal surface, said surfaces being adapted to receive said user's fingers during the positioning of said shield onto said mask, and the second lock element comprises two flexible pins, each flexible pin having a proximal end and a distal end, being oriented substantially parallel to said substantially linear movement, being attached to the grasping unit by their proximal ends and having at their distal ends a hook, each hook being turned outwards with respect to the other flexible pin, and the first lock element comprises a plane having an opening passing through the plane, wherein in locking position, both of the flexible pins extend through the opening and create a snap fit with respect to the opening, and said hooks press along sides of said opening,
• wherein pulling of the grasping unit in a direction opposed to the mask bends the flexible pins inward toward one another such that the hooks withdraw from the sides of the opening, and wherein the snap fit is maintained solely by an elasticity of flexure of the flexible pins.
