Definitions

  • This application is directed to a helmet and a method of assembling the helmet.
  • One or more embodiments of the present invention generally relate to safety equipment, and more particularly for example, to protective helmets that protect the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions.
  • Action sports e . g ., skateboarding, snowboarding, bicycle motocross (BMX), downhill mountain biking, and the like
  • motorsports e . g ., off-road and on-road motorcycle riding and racing
  • traditional contact sports e . g ., football and hockey
  • Current "state of the art” helmets are not keeping pace with the evolution of sports and the capabilities of athletes.
  • science is providing alarming data related to the traumatic effects of both repetitive but moderate, and severe impacts to the head. While concussions are at the forefront of current concerns, rotational brain injuries from the same concussive impacts are no less of a concern, and in fact, are potentially more troublesome.
  • US 2015/157082 A1 discloses a safety helmet, wherein the inner and outer liners thereof are coupled to each other so as to form an internal subassembly by the use of a plurality of resilient structures.
  • a head-side insert comprises an elevation which projects into the region of a shell-side insert.
  • the elevation is surrounded by a damping means which is compressed during a blow from the front, while the head side insert rotates backwards together with the outer shell.
  • US 2001/032351 A1 discloses a helmet including a shell and a shock absorbing liner that is split into an outer liner and an inner liner.
  • the outer liner and the inner liner have respective dents or recesses, opposite to each other.
  • a layer of an absorbent elastic body stuck to the outer liner and the inner liner.
  • US 2013/247284 A1 discloses a head protection. There is a shell and two layers of liner material. A device is placed therebetween. The device comprises a liquid or gel like material in a bladder that flexible inner and outer walls to float or slide relative to one another.
  • Omnidirectional impact energy management systems are provided for protective helmets that can significantly reduce both rotational and linear forces generated from impacts to the helmets over a broad spectrum of energy levels.
  • Embodiments enable the production of hard-shelled safety helmets that can provide a controlled internal omnidirectional relative displacement capability, including relative rotation and translation, between the internal components thereof.
  • the systems enhance modern helmet designs for the improved safety and well-being of athletes and recreational participants in sporting activities in the event of any type of impact to the wearer's head.
  • These designs specifically address, among other things, the management, control, and reduction of angular acceleration forces, while simultaneously reducing linear impact forces acting on the wearer's head during such impacts.
  • omnidirectional impact energy management systems for helmets are provided that can significantly reduce both rotational and linear forces generated from impacts imparted to the helmets.
  • the systems enable a controlled internal omnidirectional relative displacement capability, including relative rotational and translational movement, between the internal components of a hard shelled safety helmet.
  • One or more embodiments disclosed herein are particularly well suited to helmets that can provide improved protection from both potentially catastrophic impacts and repetitive impacts of varying force that, while not causing acute brain injury, can cause cumulative harm.
  • the problem of cumulative brain injury i.e ., Second Impact Syndrome (SIS)
  • SIS Second Impact Syndrome
  • helmets are configured with dampers of specific flex and compression characteristics to manage a wide range of repetitive and severe impacts from all directions, thus addressing the multitude of different risks associated with diverse sports, such as football, baseball, bicycle riding, motorcycle riding, skateboarding, rock climbing, hockey, snowboarding, snow skiing, auto racing, and the like.
  • Head injuries result from two types of mechanical forces - contact and non-contact. Contact injuries arise when the head strikes or is struck by another object. Non-contact injuries are occasioned by cranial accelerations or decelerations caused by forces acting on the head other than through contact with another object, such as whiplash-induced forces. Two types of cranial acceleration are recognized, which can act separately or in combination with each other. “Translational” acceleration occurs when the brain's center of gravity (CG), located approximately at the pineal gland, moves in a generally straight line. “Rotational” or angular acceleration occurs when the head turns about its CG without linear movement of the CG.
  • CG center of gravity

After a set amount of deflection, the inner liner 1504 may contact and/or "engage" the lug 1550. As such, the lug 1550 may then provide additional resistance towards movement of the inner liner 1504. When the lug 1550 is initially engaged, the secondary damper 1552 may not contact a component of the helmet 1500 (e.g., an outer shell or another contact).
  • a component of the helmet 1500 e.g., an outer shell or another contact.
  • the secondary damper 1552 may not be resisting movement of the inner liner 1504. After additional deflection, the secondary damper 1552 may then engage and the resistance towards movement of the inner liner 1504 may then increase due to the engagement of the secondary damper 1552 (assuming the rates of the lug 1550 and the secondary damper 1552 are constant). The combined spring rate of the lug 1550 and the secondary damper 1552 may be higher than that of just the lug 1550 itself.
