Multi-body helmet construction with shield mounting
View Patent ↗A helmet can comprise an upper-body and a lower-body nested within the upper-body. An opening can be formed within a front portion of the helmet and disposed between an outer surface of the upper-body and an inner surface of the lower-body. A first magnet can be encased within the upper-body or the lower-body and adjacent the opening. A shield can comprise a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably coupled to the first magnet. The first magnet and the second magnet can be self-aligned in direct alignment with eyes of a user. A third magnet can be disposed above the first magnet and aligned with the second magnet on an outer surface of the helmet out of sight from eyes of the user.

a shield comprising a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and adapted to be releasably coupled to the first magnet with a magnetic field.
2. The helmet of claim 1 , wherein the first magnet comprises a surface that is substantially coplanar with a surface of the opening.
3. The helmet of claim 1 , wherein:
the upper-energy absorbing material comprises expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO); and
the lower-energy absorbing material comprises EPP, EPS, EPU, or EPO.
4. The helmet of claim 3 , wherein:
the upper-energy absorbing material comprises a density in a range of 70-100 g/L; and
the lower-energy absorbing material comprises a density in a range of 50-80 g/L.
5. The helmet of claim 1 , wherein the first magnet and the second magnet are self-aligned with respect to each other such that the shield magnetically couples to the upper-body or the lower-body in direct alignment with eyes of a user.
6. The helmet of claim 1 , further comprising:
a third magnet encased within the upper-body or the lower-body adjacent the first magnet; and
the second magnet adapted to be coupled to both the first magnet and the third magnet.
7. A helmet comprising:
an upper-body;
a lower-body nested within the upper body such that a lower portion of the lower outer shell is not covered by, and remains exposed with respect to, the upper-body;
an opening formed within a front portion of the helmet and disposed between the upper-body and the lower-body;
a first magnet encased and in-molded within the upper-body without extending into the opening, the first magnet disposed between an outer surface of the upper-body and the opening or encased and in-molded within the lower-body without extending into the opening, the first magnet disposed between the inner surface of the lower-body and the opening; and
a shield comprising a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably coupled to the first magnet.
8. The helmet of claim 7 , wherein the first magnet is disposed between an outer surface of the upper-body and the opening or between an inner surface of the lower-body and the opening.
9. The helmet of claim 8 , wherein the first magnet comprises a surface that is substantially coplanar with a surface of the opening.
10. The helmet of claim 7 , wherein:
the upper-body comprises an upper energy-absorbing material comprising expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO); and
the lower-body comprises a lower energy-absorbing material comprises EPP, EPS, EPU, or EPO.
11. The helmet of claim 10 , wherein:
the upper-energy absorbing material comprises a density in a range of 70-100 g/L; and
the lower-energy absorbing material comprises a density in a range of 50-80 g/L.
12. The helmet of claim 7 , wherein the first magnet and the second magnet are self-aligned with respect to each other such that the shield magnetically couples within the opening in direct alignment with eyes of a user.
13. The helmet of claim 7 , further comprising:
a third magnet disposed within the upper-body or the lower-body and adjacent the first magnet; and
the second magnet adapted to be coupled to both the first magnet and the third magnet.
14. A helmet comprising:
an upper-body;
a lower-body nested within the upper-body;
an opening formed between the upper-body and the lower-body;
a first magnetic component encased within the upper-body between an outer surface of the upper-body and the opening or encased within the lower-body between an inner surface of the lower-body and the opening; and
a shield comprising a shield mount that is sized to fit within the opening and releasably couple to the first magnetic component; wherein the first magnet component is in-molded within the upper-body or the lower-body without extending into the opening.
15. The helmet of claim 14 , wherein the shield is magnetically coupled within the opening.
16. The helmet of claim 15 , further comprising:
the first magnetic component disposed between an outer surface of the upper-body and the opening or between an inner surface of the lower-body and the opening; and
a second magnetic component coupled to the shield mount.
17. The helmet of claim 14 , wherein:
the upper-body comprises an upper energy-absorbing material comprising expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO); and
