A system and method for a protection helmet which has exterior moveable tiles to move upon impact and then retract to their original placements. The system prolongs the impact time by de-accelerating it and minimizing its damaging effects by spreading out the impact force over a larger surface area. A system and method for a helmet's face mask to absorb impact and return back to its original state whether impacted on its bars, interior/exterior assembly, or any part of the face mask. A system and method for a football helmet's padding to be multi-layered and have multiple ancillary cavities that compress and retract back to their original state.

A hard hat and related impact protection layer is shown. The hard hat includes one or more feature to improve support of the impact protection layer and coupling of the hard hat to the user. Various suspension mechanisms for hard hat outer shells and strap systems are described herein.

A hard hat and related impact protection layer is shown. The hard hat includes one or more feature to improve support of the impact protection layer. The impact protection layer is designed to improve impact energy absorption provided by a crushable material located within the hard hat shell.

A chin-bar for a helmet with a crumple zone and an integrated air-flow system formed from passages running internally from the bottom to the top of the chin-bar. A scoop at the bottom of the chin-bar controls air flow. Diffusers at the top provide de-misting and fresh air to the rider.

The invention relates to a multi-step method with a number of processes and sub-processes that interact to allow for the selection, design and/or manufacture of a protective sports helmet for a specific player, or a recreational sports helmet for a specific person wearing the helmet. Once the desired protective sports helmet or recreational sports helmet is selected, information is collected from the individual player or wearer regarding the shape of his/her head and information about the impacts he/she has received while participating in the sport or activity. The collected information is processed to develop a bespoke energy attenuation assembly for use in the protective helmet. The energy attenuation assembly includes at least one energy attenuation member with a unique structural makeup and/or chemical composition. The energy attenuation assembly is purposely engineered to improve comfort and fit, as well as how the helmet responds when an impact or series of impacts are received by the helmet.

A helmet includes a shell, a brim, ridges, and multiple flexible structures. The shell is shaped to receive a user's head. The brim covers the user's forehead and areas above the temples and ears and protrudes from the outer surface of the shell. The ridges are located along the back and top of the helmet and also protrude from the outer surface of the shell. The flexible structures, which are made of a material that is more flexible than the shell, the brim, and the ridges, are positioned in separation gaps between the shell and the brim and ridges. The shell, brim, ridges, and flexible structures are fused together as a single unibody. When the helmet is subjected to an impact on the brim or the ridges, the corresponding flexible structure deforms so that the brim or ridge moves relative to the shell. The deformation of the flexible structure attenuates the force of the impact, which improves the helmet's ability to protect the user from impacts.

The present disclosure discloses a helmet with a split type skeleton structure. The helmet includes a helmet body; the helmet body is composed of a head guard and a chin guard which are separated; the head guard and the chin guard are mounted through cooperation between a fastened spliced skeleton and a plug pin; the spliced skeleton is composed of two skeleton connection members arranged inside the head guard and a chin skeleton arranged inside the chin guard; and hollows of a surface of the chin skeleton are fixedly connected with a plurality of one-piece structured reinforcing ribs.

An impact protection device includes a first shell configured to be disposed on a body portion of a user, a second shell spaced at a distance from the first shell, and a set of elastomeric members spanning the distance between the first shell and the second shell. Each elastomeric member includes a first end and an opposing second end, each first end comprises a first end portion disposed within a corresponding opening defined by the first shell and a terminal portion disposed against an inner wall of the first shell and each second end connected to the second shell. The set of elastomeric members are configured to stretch between the first shell and the second shell in response to a translation of the second shell relative to the first shell and at a location that is substantially opposite to an impact receiving location of the second shell.

A lace dial system (5810) has a first rack (5850A), a second rack (5850B), a frame (5840), a pinion (5870), a brake (5860), and a lace (5830). The first rack has a set of teeth (5850A3), and a first end (5850A5). The second rack has a set of teeth (5850B3), and a first end (5850B5). The pinion has a body and a set of teeth (5870A) extending longitudinally from the body and engaging with the teeth on the first and second racks. The brake allows rotation of the pinion only when a rotation force applied to the pinion exceeds a predetermined, non-trivial amount. Rotating the pinion in a first direction causes the first end of the first rack and the first end of the second rack to move toward each other, wherein the lace is tightened. Rotating the pinion in a second, opposite direction causes the lace to be loosened.

An impact-absorbing structure that includes a plurality of interconnected cells forming a sheet, each cell having a sidewall and a longitudinal axis. Each cell may be configured to absorb energy through plastic deformation in response to an applied load, and a sidewall of at least one cell may include a geometric perturbation that is oriented in a direction that is not parallel to the longitudinal axis of the cell. The geometric perturbation may reduce the load required to cause plastic deformation of the cell.
