- It has been well known in the welding art for a welder to wear a helmet in order to protect the welder's face from sparks as well as providing a tinted sight window to protect the welder against damage to the eyes due to the intense flash caused by electric arc welding, and other welding processes. A typical welder's helmet utilizes a nearly opaque or light radiation absorbing window to block the intense arc light, but still allow the welder to view the workpiece on which he is working.
- Accordingly, welding masks have been designed to sufficiently protect the welder against damage to the eyes and against sputtering or thrown particles of metal that are otherwise projected toward the welder's face.
- There are further known welder's helmet designs that include means for protecting a welder against poisonous or noxious fumes and gases that are commonly given off by the welding rods. Although these known welder's helmets with means for protecting a welder against poisonous or noxious fumes present an advancement in the welding art for protecting the welder, it is still desirable in the welding art to provide a welder's helmet with a respirator that is more suitably adapted to the individual welder's face, provides a better airtight sealing around the user's nose and mouth, and provides reduced obstruction to the user's vision.
- Accordingly, the welder's helmet, according to the principles of the present invention, provides a respirator mask having an independent strap for ensuring that the respirator mask is securely fitted to a user's face. In addition, the respirator mask includes a pair of filters that are received in respective openings in the welder's mask that are disposed to separate sides thereof so as to reduce the obstruction of the welder. Finally, a foam interior mounting structure is provided inside of the helmet to accommodate for variances in welders' faces. In particular, the foam interior mounting structure can be adapted by adding additional layers of foam for mounting the respirator mask within the welder mask.
- Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
