What is claimed is: 1. A helmet assembly being configured to operably secure one or more distinct accessory units thereto, said helmet assembly comprising: a helmet body; an attachment profile disposed on and extending inwardly from an inner surface of said helmet body; and a mating structure attached to each of said one or more accessory units, said mating structure being specifically configured to matingly engage with said attachment profile so as to provide for selective securement of said one or more accessory units to said helmet body, said mating structure including a sealing portion which sealingly engages with said inner surface of said helmet body when said mating structure is matingly engaged with said attachment profile. 2. A helmet assembly as in claim 1 wherein said attachment profile is configured to operably receive and simultaneously secure a plurality of said accessory units, each having a respective mating structure attached thereto. 3. A helmet assembly as in claim 1 wherein said helmet body is a welder's helmet. 4. A helmet assembly as in claim 3 wherein said one or more accessory units includes a face seal. 5. A helmet assembly as in claim 1 wherein said attachment profile is integrally formed with said helmet body. 6. A helmet assembly as in claim 5 wherein said attachment profile is molded with said helmet body in a one-step molding process. 7. A helmet assembly as in claim 1 wherein said attachment profile comprises at least one protrusion extending substantially about an inner periphery of said helmet body. 8. A helmet assembly as in claim 1 wherein said attachment profile comprises a plurality of protrusions extending substantially concentrically about an inner periphery of said helmet body. 9. A helmet assembly as in claim 1 wherein said attachment profile comprises a series of protrusions intermittently disposed adjacent to a periphery of said helmet body. 10. A method for selectively securing one or more distinct accessory units to a helmet body, comprising: (a) providing an attachment profile on an inner surface of said helmet body; (b) providing a mating structure on each of said one or more distinct accessory units, said mating structure being specifically configured to matingly engage with said attachment profile, said mating structure including a sealing portion which sealingly engages with said inner surface of said helmet body when said mating structure is matingly engaged with said attachment profile; and (c) placing said mating structure of respective ones of said accessory units in registration with said attachment profile.
