Devices that facilitate offsetting of weight of heard borne equipment such as helmets and other devices associated with helmets are provided. Through the use of pivots and an arm assembly that distributes weight from a person's head to his or her torso, additional and heavier objects can be carried on a person's head without causing undesirable levels of discomfort.

In one embodiment, a tether system for use with a protective helmet worn by a user includes multiple tethers, each tether having a first end adapted to attach to a shell of the protective helmet and a second end adapted to attach to an article worn by the user, wherein the tethers limit movement of the helmet.

There is disclosed universal pumper skirt for use with a helmet. The universal pumper skirt is composed of a coif wrapping around a wearer's neck and connected to a helmet. The coif includes an air connection input port on the coif. A wearer can use an air flow unit to pump air through the input port, creating positive air pressure in the coif and helmet that cool the wearer and reduce the intrusion of dust into the helmet. The coif may be removably attached to a motorcycle or motorsport helmet, therefore, a wearer can remove the universal pumper skirt from a helmet or transfer it to a different helmet.

A head, neck and shoulder protection assembly for protecting the head, neck and shoulders of a user includes a pair of shoulder pads. A helmet, which has a bottom edge defining an opening, is reversibly couplable to the shoulder pads. The bottom edge is substantially complementary to an upper surface of the shoulder pads. The helmet is couplable to the shoulder pads such that the helmet is fixedly positioned relative to the shoulder pads. The opening is configured for insertion of the user's head into the helmet. The helmet is positioned to couple to the pair of shoulder pads, such that movement of the helmet relative to the shoulder pads is restricted. The helmet is dimensionally larger than the head and neck of the user, such that the user has full range of movement of the head and neck of within the helmet without the user's head contacting the helmet.

In an aspect, a stress mitigation system is provided for mitigating stresses in a wearer of a headgear configured to apply a load on the wearer that is offset from a center of gravity of the wearer's head to apply a first torque in a first direction on the wearer's head. The system includes a track, a shuttle, and a flexible elongate connector. The track is mounted to either the headgear or a bodywear member and extends generally laterally. The shuttle is movable along the track. The connector is configured to connect between the shuttle and the other of the headgear and the bodywear member. The connector applies a second torque on the headgear in a second direction that is generally opposite to the first direction. When the wearer's head pivots, the shuttle is movable laterally along the track to maintain the connector in a substantially vertical orientation.

A neck support system to prevent hyperflexion and hyperextension of a spinal cord of a user and enhance user safety connects to both a helmet and shoulder pads worn by the user. The system includes a housing unit having an opening and a first fastening component coupled to a second fastening component disposed on the shoulder pads, a strap retractor mechanism disposed within the housing unit, a strap having a first end coupled to the strap retractor mechanism and a second end having a third fastening component coupled to a fourth fastening component disposed on the helmet. The retractor mechanism enables the extension and retraction of the strap through the housing unit opening to permit freedom of movement of the user's neck. The retractor mechanism locks the strap in a stationary position when a force applied to the strap exceeds a predetermined magnitude of force.

Whiplash reduction systems and devices and methods to use the same. In an embodiment of a system of the present disclosure, the system comprises a front anchor strap coupled directly or indirectly to a headgear; a top anchor coupled to the front anchor strap, the top anchor having a connector coupled thereto, the connector configured to connect to at least one rear strap; a first retainer configured to fit within apertures defined within the headgear and to wrap around at least part of the headgear and at least part of the front anchor strap to secure the front anchor strap to the headgear at or near the apertures; and a plate having a central portion defining a recessed portion and further having a first side portion and a second side portion.

A system and various methods for monitoring and evaluating the health of a shock strut assembly are illustrated. Multiple sensors, including gas temperature, gas pressure, oil pressure, and position sensor, may be used to gather data and evaluate the performance of the shock strut assembly. Various methods illustrated herein may evaluate the dynamic damping, static load support, and/or controlled stroke performance of the shock strut assembly.
