first embodiment
[0015] the chassis can include a channel 110 along both of the inner and outer curves. In multi-piece embodiments, the channel accepts a vertical return section, as shown in FIG. 2A. This vertical return 211 section includes mounting points for the shield. The inner vertical return 212 includes mounting points for a forehead pad and head strap. Constructing the shield in this way allows the shield to be shipped flat, and to be manufactured in two-dimensional sheet. The pieces can be assembled in order to create the three-dimensional part.
[0016]FIGS. 2A and 2B depict an embodiment of FIG. 1 where the vertical return portions are inserted into the chassis 201. FIG. 2A depicts the returns 211 and 212 inserted into the channels to provide a return for attachment of accessories, such as a shield and comfort / retention mechanisms. Comparing FIG. 1 and FIG. 2A and B, it is clear to see the additions of these vertical portions, or returns, as they are placed in the channels depicted in FIG. ...
embodiment 350
[0022]In various other embodiments, a more traditional face shield may be used, including with embodiment 350, such as the one depicted in FIG. 3B, that do not include the extended wings or the taper. Or, in various embodiments, the extended wings 356 may extend all the way down to the lower end of the shield. The user may select from various shield types as well, as the shields are readily removable and replaceable.
[0023]FIG. 3B depicts a complete example of an embodiment of the present invention. The combination of the chassis, the head strap, foam strip, mounting hardware, and shield should preferably weigh less than 8 ounces. Said another way, the complete face shield apparatus preferably weighs less than 8 ounces. The complete face shield can also weigh less than 7 ounces, or 6 ounces, or 5 ounces. The depicted apparatus may be manufactured using CNC, table mills, routers, injection molding, 3D printing or the like, and can be manufactured and shipped flat.

embodiment 450
[0028]FIG. 4D depicts a close up of the embodiment 450. As shown, a pocket 463 is formed near the distal ends of the inner return 462, between the inner return and the chassis 451. This pocket 463 slightly weakens the distal end of the inner return 462. This way, the distal ends of the inner return can bend into the free space formed by the pocket 463. In doing so, the chassis 451 is able to accommodate larger head sizes. When a user with a larger head wears the device, the distal portions of the inner return bend into the free space as necessary, to the point where they may contact the chassis, in order to accommodate various head sizes. Constructing the inner return in this manner also provides slight pressure against the wearer's head, as the inner return attempts to return to its original shape. This slight spring effect increases the stability to the device without introducing any discomfort. An additional benefit of the space between the inner return and the remainder of the c...
