The present disclosure relates to a dual helmet that can be easily converted into two sets of helmets having protective cushioning, and which are comfortable, yet strong, safe, and up to the required standards The helmet includes a first shell and a second shell defining a shell of a first helmet and a second helmet, respectively. The second shell is removably disposed over the first shell such that the helmet can be used as a single combine helmet when the shells are together, and further, the second shell can be separated from the first shell to form two separate helmets. The helmet includes a first cushion disposed within the first shell, and a second cushion for the second helmet being removably configured within the first cushion such that the second cushion can be separated by slightly ending it, and later can be configured with the second shell to form the second helmet and the first helmet, as required.

A helmet pad includes a substrate having first side attachable to an interior surface of a helmet. The helmet pad includes an outer lattice layer peripherally attached to a second side of the substrate. The second side is opposite to the first side. In one embodiment, the outer lattice layer includes fibers attached in one of: (i) a Voronoi lattice unit cells; and (ii) tetrahedral lattice unit cells. The helmet pad includes padding material received in an enclosure between the second surface of the substrate and the outer lattice layer.

A body limb protection system includes an outer layer, an inner layer, and a force dampening and defusing structure. The outer layer includes a first material composition and has an exterior surface that includes a substantially planer area. The inner layer includes a second material composition and has a shape corresponding to a body limb portion. The force dampening and defusing structure is positioned between the inner layer and the outer layer. The force dampening and defusing structure has a shape corresponding to a difference between the shapes of the inner and outer layers. The force dampening and defusing structure includes a plurality of components arranged to reduce pressure on the body limb portion when a force is applied to the substantially planer area.

An energy dissipating helmet, such as a football, baseball, hockey, construction, combat, bicycle, or motorcycle helmet, including a structural component adapted to receive an anticipatory impact having energy, and a stress-activated active material element, such as a Austenitic shape memory alloy wire, mesh, layer, or spring, communicatively coupled to the component, and activatable by the impact, so as to dissipate at least a portion of the energy.

A garment worn by a wearer has an exterior shell and an interior shell with various impact absorbing material between the exterior shell and the interior shell. The impact absorbing material includes multiple structures, such as rods or filaments, capable of deforming when force is applied then returning to its state prior to application of the force. In various embodiments, a rate sensitive material (RSM) is positioned in one or more locations relative to the exterior shell and the interior shell of the garment to further attenuate impacts to the garment. The RSM changes its resistance to force based on a rate at which the material is loaded.

The present invention is a helmet system that reduces concussions by damping rotational force transmitted to a helmet user. The helmet has an exterior shell and an internal body that moves independently from the exterior shell. At least one magnetic source on the exterior shell's interior has a dipole directed axially at the internal body. At least one magnetic source on the internal body has a dipole aligned with the same axis, directed at the exterior shell. In a resting state magnetic sources generate a weak magnetic field. When an impact rotates the exterior shell, it moves off the initial alignment and closer to the internal body. The previously aligned magnetic sources torque. The magnetic source on the internal body torques in the opposite direction of the rotation, as do all initially aligned magnetic sources impacted. Angular momentum is displaced, diffused, offset, damping rotational force transmitted to a helmet user.

This disclosure provides a method for making a helmet comprising a cavity between the outer shell and energy management layers.

There is provided an elastomeric sheet with a thickness of from 5 mm to 20 mm the elastomeric sheet having with a first side and a second side, where the first side has a plurality of deformable support members where the support members have a cavity with an opening towards the second side of the elastomeric sheet, and where the hardness of the sheet is from 40 Shore A to 80 Shore A.

A helmet comprising first and second parts and a connector connecting the first and second parts of the helmet, the connector comprising: a first plate; a first anchor point on one side of the first plate, configured to be connected to the first part; a second plate located on an opposite side of the first plate from the first anchor point; a second anchor point on an opposite side of the second plate from the first plate, configured to be connected to the second part; a low friction interface provided between opposing surfaces of the first and second plates; and a cuff of deformable material provided around the first and second plates, and configured to at least partially cover the side of the first plate on which the first anchor point is located and to at least partially cover the side of the second plate on which the second anchor point is located.
