A pivoting protective headgear system includes a head suspension and two pivots coupled to the head suspension. A protective headgear element is pivotally connected to each pivot. In one exemplary embodiment, two transition arms are coupled to the head suspension and extend longitudinally extending away from the head suspension, and each transition arm has a distal end and a pivot at the distal end. In another exemplary embodiment, two pivots are coupled to the head suspension and each pivot has an axis of rotation configured to be below any portion of an ear of a user. In a further exemplary embodiment, two pivots are each spaced apart from the headband and coupled to the headband, and the headband is configured to be disposed against a forehead of a user and each pivot has an axis of rotation below the headband. |

1. A pivoting protective headgear system comprising:
a head suspension having a laterally extending headband adapted to extend about a user's head, which laterally extending headband comprises a front portion that is adapted to be disposed against the forehead of a user; first and second transition arms that are located on laterally-opposite sides of the headband, each transition arm being non-pivotally connected to the headband of the head suspension at a proximal end of the transition arm, each transition arm longitudinally extending away from the headband to comprise an elongate length and a distal end, and each transition arm having a pivot at the distal end of the transition arm,
and wherein the pivot of the first transition arm, and the pivot of the second transition arm, each comprise an axis of rotation that is below the entirety of at least a lower edge of at least the front portion of the headband; and a single protective headgear element that is a welding helmet and that is pivotally connected to the pivot of the first transition arm and to the pivot of the second transition arm,
wherein the head suspension comprises a first top band that is adapted to extend over the user's head and that comprises first and second ends each of which are joined to the laterally extending headband; and, a second top band that is adapted to extend over the user's head and that comprises first and second ends each of which are joined to the laterally extending headband, and wherein the first top band and the second top band are non-overlapping top bands, said first and second top bands each having a length, and said first and second top bands spaced apart from one another along their entire lengths, and spaced apart from each other along a front-rear direction of the head suspension,wherein each transition arm has a length in a range from 2 to 10 centimeters,and wherein each pivot exhibits an axis of rotation that is longitudinally spaced away from the headband a distance of from 2 to 10 cm. |
