Helmet comprising a segmented shell
A helmet can include a helmet body comprising an energy-absorbing layer and an outer shell disposed over the energy-absorbing layer. An electronic device can be integrated with the helmet body. A first electrical contact can be formed at an exterior of the outer shell and adapted to be in electrical communication with the electronic device. A helmet visor can be coupled to the helmet body with at least one visor arm, the helmet visor comprising controls integrated within the visor. A second electrical contact can be formed at an inner surface of the at least one visor arm and adapted to be in electrical communication with the controls integrated within the visor. The second electrical contact can be adapted to mateably couple with the first electrical contact such that the electronic device and the controls are adapted to be in electrical contact.
1. A helmet comprising:
a segmented outer shell comprising:
an upper portion,
a lower portion, wherein the upper portion and the lower portion define an overlap of 0-20 mm, and
a reinforcement member disposed between the upper portion and the lower portion to create an elongated segmented opening in the outer shell;
an energy management liner disposed within the segmented outer shell and further comprising:
an outer energy management layer comprising an opening formed completely through the outer energy management layer, and
an inner energy management layer disposed within the outer energy management layer, the inner energy management layer comprising a channel formed completely through the inner energy management layer that is aligned, and overlaps at least 1 centimeter (cm), with the opening in the outer energy management layer and facilitates airflow through the elongated segmented opening.

the upper portion of the segmented outer shell covers a top and a crown of the helmet;
the lower portion of the segmented outer shell covers a side and a rear of the helmet; and
the elongated segmented opening extends along an interface of the upper portion of the segmented outer shell and the lower portion of the segmented outer shell from an a-pillar of the faceport toward the rear of the helmet.
4. The helmet of claim 1 , wherein the reinforcement member is formed as a bushing coupled to a pin formed of a unitary construction with either the upper portion of the segmented outer shell or the lower portion of the segmented outer shell.
5. The helmet of claim 1 , wherein the reinforcement member is formed as a bushing made of a material softer than the outer shell.
6. The helmet of claim 1 , wherein the elongated segmented opening comprises a length in a range of 3-20 cm.
7. The helmet of claim 1 , wherein:
the outer energy management layer is formed of expanded polystyrene (EPS); and
the inner energy management layer is formed of expanded polypropylene (EPP).
8. A helmet comprising:
a segmented outer shell comprising a first portion and a second portion, wherein the first portion and the second portion define an overlap of 0-20 mm, the segmented outer shell defining an elongated segmented opening;
an energy management liner disposed within the segmented outer shell and further comprising;
an outer energy management layer comprising openings formed completely through the outer energy management layer, and
an inner energy management layer disposed within the outer energy management layer, the inner energy management layer comprising channels formed completely through the inner energy management layer that are aligned, and overlap by at least 1 centimeter (cm), with the openings in the outer energy management layer and facilitate airflow through the elongated segmented opening.
9. The helmet of claim 8 , wherein the elongated segmented opening comprises a length greater than 3 cm and a height greater than 0.2 cm without a radial line of sight being formed from without the helmet to the energy management liner.
10. The helmet of claim 9 , wherein:
the first portion of the segmented outer shell covers a top and a crown of the helmet;
the second portion of the segmented outer shell covers a side and a rear of the helmet; and
the elongated segmented opening extends along an interface of the upper portion of the segmented outer shell and the lower portion of the segmented outer shell from an a-pillar of the faceport to a rear of the helmet.
11. The helmet of claim 8 , wherein the segmented outer shell further comprises:
a reinforcement member disposed between the first portion and the second portion to create the elongated segmented opening in the outer shell.
12. The helmet of claim 11 , wherein the reinforcement member is formed as a bushing made of a material softer than the outer shell.
13. The helmet of claim 11 , wherein the reinforcement member is coupled to pins formed of unitary construction with either the first portion of the segmented outer shell or the second portion of the segmented outer shell.
14. The helmet of claim 11 , wherein the elongated segmented opening comprises a length in a range of 1-20 cm.
15. A helmet comprising:
a segmented outer shell comprising:
an upper portion,
a lower portion, wherein the upper portion and the lower portion define an overlap of 0-20 mm, and
a reinforcement member disposed between the upper portion and the lower portion to create an elongated segmented opening in the outer shell; and
an energy management liner disposed within the segmented outer shell and further comprising a channel formed completely through the inner energy management layer that is aligned, and overlaps at least 1 centimeter (cm), with the opening in the outer energy management layer and facilitate airflow through the elongated segmented opening.
16. The helmet of claim 15 , wherein the elongated segmented opening comprises a length greater than 3 cm and a height greater than 0.2 cm without a radial line of sight being formed from without the helmet to the energy management liner.
17. The helmet of claim 15 , wherein:
the upper portion of the segmented outer shell covers a top and a crown of the helmet;
the lower portion of the segmented outer shell covers a side and a rear of the helmet; and
the elongated segmented opening extends along an interface of the upper portion of the segmented outer shell and the lower portion of the segmented outer shell from an a-pillar of the faceport to the rear of the helmet.
