What is disclosed herein is a helmet safety device. The helmet safety device comprises a predetermined length of auto racing harness strapping having two ends, each end having a fastening buckle that fastens to an auto racing helmet. The strapping is comprised of short lengths of auto racing harness strapping, held together in a plurality of locations along said strapping, by tear away stitching thread.

Systems and methods for selectively attaching an accessory mount to a helmet are disclosed. A carrier may be used to position the accessory mount on the helmet. The accessory mount may be positioned on the helmet without engaging the rim of the helmet. The carrier may be compatible with various accessory mounts to permit mounting of different accessories. The accessory mount may be a powered mount for attachment to a Night Vision Device (NVD) such as Enhanced Night Vision Goggles (ENVG), or the accessory mount may be a non-powered accessory mount.

A head mounted device for a helmet includes a connection module, a flexible bracket, a power supply seat and a function module. While the flexible bracket is moved relative to the connection module, a position of the power supply seat relative to the helmet is adjusted. While the function module is moved relative to the power supply seat, an orientation of the function unit is adjusted.

A combined microphone and fluid-delivery apparatus includes a microphone disposed at an end of a support member, and a fluid passageway supported by the support member. A mouthpiece extends from the passageway so as to be positioned adjacent the microphone. The mouthpiece defines an outlet port that is in fluid communication with the fluid passageway.

The present invention provides a smart helmet falling detection method and a smart helmet. The falling detection method includes following steps: initializing a system, determining a free fall, determining a collision, determining motionlessness, and generating an emergency signal according to a detection result that a motionlessness event occurs within a fourth duration after the collision event occurs. The smart helmet includes a three-axis acceleration sensor and a controller. For the smart helmet falling detection method and the smart helmet provided in the present invention, the acceleration is measured by the three-axis acceleration sensor installed on the smart helmet, and whether a riding falling event occurs is determined by analyzing change of the acceleration, and alarm is given according to the falling event, such that the problem of falling detection and calling for help in a riding process is solved in a targeted manner.

A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a bulge or protrusion over the ear.
