A rotational engagement component to engage a lens for facial protection, to headwear such as a helmet worn on the head of a user. The device features one or a plurality of mounts engageable to the helmet. A pivot engaged with the mount and with the lens, allow rotation of the lens from an as-used position in front of the user, to a horizontal stowed position. The pivot is translatable in its engagement to the mount allowing for translation of the lens in the stowed position to adjust its center of gravity on the user's head.

1. A rotational engagement of a face shield for facial protection, to headwear such as a helmet worn on the head of a user, comprising: a mount engageable to said helmet between a front end of said helmet positioned above the eyes of said user wearing said helmet, and a rear end of said helmet opposite said front end;a pivot in engaged upon said mount;means for an attachment of a lens, to said pivot;said lens in said attachment, rotatable from an as-used position substantially vertical position in front of the face of a user, to a stowed position substantially horizontal and above the eyes of said user;said pivot translatable in said engagement to said mount toward and away from said rear end, between a first point furthest from said rear end and a second point closest to said rear end;a translation of said pivot in a direction toward said rear end, producing a sliding of said lens a distance toward said rear end, equal to said translation; andsaid sliding of said lens along said distance, providing means to adjust a center of gravity of said lens, upon said head of said user. 2. The rotational engagement of a face shield of claim 1, additionally comprising: a pair of said mounts, each of said pair engaged to a respective opposing side surface of said helmet;each of said pair of mounts having one of a pair of pivots engaged thereon;means for an attachment of a lens, to each of said pair of pivots;each of said pair of pivots translatable in said engagement to a respective said mount, toward and away from said rear end, between a first point furthest from said rear end and a second point closest to said rear end;a translation of said pair of pivots pivot in a direction toward said rear end, producing a sliding of said lens a distance toward said rear end, equal to said translation. 3. The rotational engagement of a face shield of claim 1, additionally comprising: means for rendering said pivot translatable in said engagement to said mount, only with said lens rotated to said stowed position. 4. The rotational engagement of a face shield of claim 2, additionally comprising: means for rendering said pair of pivots translatable in said engagement to a respective said mount, only with said lens rotated to said stowed position. 5. The rotational engagement of a face shield of claim 3, wherein said means for rendering said pivot translatable in said engagement to said mount, only with said lens rotated to said stowed position comprises: said means for an attachment of a lens, to said pivot comprising a substantially planar member;a slot communicating through said member;said slot having a curved section communicating with a substantially straight section;a pin communicating from a distal end engaged in said slot, to a fixed position on said mount or helmet;said distal end engaged within said curved section of said slot until said lens is rotated to said stowed position wherein said pin is positioned at a first end of said straight section;said distal end of said pin engaged with said curved position, preventing said pivot from translating in said engagement with said mount. 6. The rotational engagement of a face shield of claim 4, wherein said means for rendering said pair of pivots translatable in said engagement to a respective said mount, only with said lens rotated to said stowed position comprises: said means for an attachment of a lens, to said pivots comprising a respective substantially planar member;a slot communicating through at least one said member;said slot having a curved section communicating with a substantially straight section;a pin communicating from a distal end engaged in said slot, to a fixed position on said mount or helmet;said distal end engaged within said curved section of said slot until said lens is rotated to said stowed position wherein said pin is positioned at a first end of said straight section;said distal end of said pin engaged with said curved position, preventing said pivot from translating in said engagement with said mount. 7. The rotational engagement of a face shield of claim 1, additionally comprising: user releasable means to lock said lens in said stowed position. 8. The rotational engagement of a face shield of claim 2, additionally comprising: user releasable means to lock said lens in said stowed position. 9. The rotational engagement of a face shield of claim 3, additionally comprising: user releasable means to lock said lens in said stowed position. 10. The rotational engagement of a face shield of claim 4, additionally comprising: user releasable means to lock said lens in said stowed position. 11. The rotational engagement of a face shield of claim 5, additionally comprising: user releasable means to lock said lens in said stowed position. 12. The rotational engagement of a face shield of claim 6, additionally comprising: user releasable means to lock said lens in said stowed position.
