Helmet configured for electronics
Integrated helmet systems provide convenient and modular use of electronic devices with a protective helmet. In addition to ease of use, weight savings and space savings also may be realized in certain embodiments. A flexible printed circuit board is used as a power bus to deliver electrical power from a battery pack to various electronic devices. Examples of devices used with protective helmets include: night vision goggles; helmet-mounted display units; ear phones; communication headsets; camera systems; biometric sensors; microprocessors; identify friend or foe devices (IFFs); and GPS devices.

5. The protective helmet according to claim 4 , wherein the at least one component contact is configured to contact a helmet-mounted display unit when the helmet-mounted display unit is attached to the helmet.
6. The protective helmet according to claim 1 , further comprising:
a removably attachable helmet-mounted display unit;
and a second connector to physically connect the helmet-mounted display unit to the helmet.
7. The protective helmet according to claim 6 , wherein:
at least one of the one or more component contacts comprises a helmet-mounted display unit contact; and
the second connector and the helmet-mounted display unit contact are constructed and arranged such that physically connecting the helmet-mounted display unit to the helmet with the second connector places the helmet-mounted display in electrical connection with the helmet-mounted display unit contact.
8. The protective helmet according to claim 1 , wherein the flexible printed circuit board includes circuitry to carry HDMI signals.
9. The protective helmet according to claim 1 , wherein the flexible printed circuit board comprises a data bus.
10. The protective helmet according to claim 9 , further comprising a data cable that is electrically connected to the flexible printed circuit board.
11. A protective helmet comprising:
a protective assembly comprising: a protective shell to protect a wearer's head;
a first connector to physically connect an electrical power source to the helmet;
a first contact to receive electrical power from the power source;
a power bus comprising: a flexible printed circuit board, wherein the flexible printed circuit board extends along a rim portion of the protective helmet, and
the flexible printed circuit board is located between a rim of the protective shell and an edge trim piece that covers the rim of the protective shell, the first contact being electrically connected to the power bus to provide electrical power to the power bus when the electrical power source is connected to the first contact;
a first component contact electrically connected to the power bus at a first location on the helmet, the first component contact being configured to deliver electrical power to a first electronic component when the first electronic component is connected to the first component contact; and
a second component contact electrically connected to the power bus at a second location on the helmet which is spaced from the first location, the second component contact being configured to deliver electrical power to a second electronic component when the second electronic component is connected to the second component contact.
12. The protective helmet according to claim 11 , wherein the power bus comprises a cable.
13. The protective helmet according to claim 11 , wherein the second component contact is configured to deliver power to the first electronic component when the first electronic component is attached to the second component contact.
14. The protective helmet according to claim 11 , further comprising the electrical power source, and wherein the electrical power source is the only electrical power source that provides power to the power bus.
15. The protective helmet according to claim 11 , further comprising a third component contact electrically connected to the power bus at a third location on the helmet which is spaced from the first and second locations, the third component contact being configured to deliver electrical power to a third electronic component when the third electronic component is connected to the third component contact.
16. A protective helmet comprising:
a protective assembly comprising:
a protective shell to protect a wearer's head;
a first contact to send and/or receive data with a device external to the protective assembly;
a flexible printed circuit board forming a data bus, wherein the flexible printed circuit board extends along a rim portion of the protective helmet, and the flexible printed circuit board is located between a rim of the protective shell and an edge trim piece that covers the rim of the protective shell, and the first contact being conductively connected to the flexible printed circuit board to provide data to and/or receive data from the flexible printed circuit board when the external device is operatively connected to the first contact; one or more component contacts conductively connected to the flexible printed circuit board, each of the component contacts being configured to send data to and/or receive data from an electronic component when the electronic component is connected to the component contact.
