A helmet comprising a first protective layer, the first protective layer comprising at least one accessory mount portion for receiving an accessory mount or an accessory, the at least one accessory mount portion being arranged integrally as a part of the first protective layer and configured to disintegrate from the rest of the first protective layer in response to a mechanical impact to the at least one accessory mount portion for preventing the accessory mount portion and/or the accessory from penetrating through the helmet.

Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.

A composite multi-axial impact protection liner for a helmet is provided that reduces rotational acceleration, rotational strain rate, and rotational strain that cause concussions. In a protective helmet so equipped, one or more layers of fluid polymer, including strain thinning and strain thickening polymers, are positioned between the wearer's head and a hard helmet shell. The liner offers greater injury protection, performance, and personal comfort using the rate dependent and combined effect of strain thinning and strain thickening of fluid polymer layers.

A helmet having an energy absorbing layer, an outer layer that is harder than the energy absorbing layer and a plurality of outer plates mounted on the outer surface of the outer layer is provided. The outer plates on the outer layer can slide across the outer layer. A low friction interface between the outer surface of the outer layer and at least a part of the outer surface of the outer plates contacts the outer surface of the outer layer under an impact.

A plate for an article of footwear includes a substrate, a first strand portion attached to the substrate via first stitching, and a second strand portion disposed on the first layer. The first strand portion includes first segments that each extend between two different locations along the substrate to form a first layer on the substrate. The second strand portion includes second segments that each extend between two different locations along the substrate to form a second layer on the first layer.

A bicycle helmet that fits over a surface of a head of a user generally includes at least one segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the at least one segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the at least one segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user.

There is described a protective helmet for sporting use, in particular for use while skiing, comprising an external cap-like structure (2) of a resiliently flexible material, an internal cap-like structure (3) which is received in the external cap-like structure (2) and which comprises a plurality of cap portions (5a, 5b) of expanded material which are structurally independent of each other and which are mutually interconnected with limited relative mobility between contiguous portions, the internal cap-like structure (3) delimiting a cavity (4) which is open towards the outer side and which is capable of receiving the head of the user, and at least one device (6) for absorbing energy as a result of forces of impacts on the helmet, which device is interposed between the internal cap-like structure (3) and external cap-like structure (2). The device comprises at least one flexible member (12) which includes a plate-like portion (12a) having a transverse thickness (13) which is defined between a pair of opposing surfaces (13a, 13b) and a plurality of reliefs (14) which project in the same direction from one of the surfaces (13a, 13b), the reliefs (14) extending with a tapering formation in the direction of the free end (14a) thereof, in the direction away from the portion (12a), and the at least one member (12) being fixedly joined to the external cap-like structure (12) in the region of the respective free ends (14a) of the reliefs (14) and the internal cap-like structure (3) in the region of the surface (13a) of the opposite portion (12a) to the portion which has the reliefs.

An impact attenuation helmet construction having a rigid outer shell, a rigid inner shell adapted to being worn upon a wearer's head and arranged a spatially separated distance from the outer shell. A plurality of resilient plasticized members, each having circular cross sectional profiles, are provided and extend between the inner and outer shells in a three dimensional array in order to spatially support said outer shell a distance from an outer surface of said inner shell. The resilient members include any of disk or sphere shaped components, each having outer and inner flattened mounting locations securing to opposing locations of the inner and outer shells.

A helmet can include an energy absorbing shell including an outer surface and an inner surface opposite the outer surface. A fit system member can be coupled to a rear of the energy absorbing shell to adjust a fit of the helmet for a user. A sliding layer can include an outer sliding layer surface oriented towards the inner surface of the energy absorbing shell and an inner sliding layer surface opposite the outer surface. The sliding layer can include at least one attachment member and at least one integrated fit system arm. The at least one integrated fit system arm can be coupled to the fit system member. An elastomeric member can include a first end coupled to the energy absorbing shell and a second end coupled to the attachment member of the sliding layer. Comfort padding can be coupled to the inner surface of the Sliding layer.
