Publication number: 20120060251Abstract: Disclosed is a protective helmet and a method for mitigating or preventing a head injury, in which a shock-absorbing, or shock-absorbing and comfort-providing, inner wearing unit, which can comprise liners, comfort pads, protective pads, nubbed cages and/or strapped wearing units (for example spider-shaped wearing elements, wearing straps, head bands or the like), is divided into a shell-side insert and a head-side insert, which can be counter-rotated (preferably starting from application of a predetermined force) in at least one direction, wherein a sliding surface is provided that assumes the function of a rotational surface, so that the angular acceleration introduced by a blow is drastically reduced or prevented because the head-side insert and the shell-side insert, and thus the head of the wearer and the outer helmet shell, can be counter-rotated quickly and without impediment, preferably in all directions.Type: ApplicationFiled: September 9, 2011Publication date: March 15, 2012Inventor: Oliver Schimpf

Patent number: 8127373Abstract: A method and system for reducing the concussive effects of impact. The system includes a helmet for protecting the head of a user. The helmet has a surface, an array of strain gauges attached on the surface for detecting an impact, an array of cells attached within the helmet and a fluid reservoir in fluid communication with the cells. Each cell is selectively inflatable to redirect impact forces to the shell of the helmet, and selectively deflatable to cushion a users head during impact. The process of inflation and deflation is enabled and optimized through the use of a microprocessor connected in operative communication with the array of strain gauges and with the valves. Accordingly, when the system detects impact, the microprocessor selectively signals at least some of the valves to rapidly change pressure in the cells near the impact.Type: GrantFiled: July 22, 2011Date of Patent: March 6, 2012Inventor: Troy Allen Fodemski

Patent number: 8117676Abstract: A hardhat provides ventilation and controlled lighting. A crown of a modified semi-spherical shape terminates downwardly with a generally oval peripheral edge in a horizontal plane, the crown having a plurality of apertures therein arranged in spaced apart sequence, and a flexible venting strip fixed forwardly on the crown and extending over the apertures, the venting strip positionable in each of a plurality of arcs above the crown, wherein each one of the arcs provides a selectable ventilation conductance into the hardhat. A brim is joined integrally to the peripheral edge of the crown extending outwardly.Type: GrantFiled: December 1, 2008Date of Patent: February 21, 2012Inventor: Jefferson Cardoso

Publication number: 20120036619Abstract: The present invention concerns a helmet with reduced weight but improves energy absorbing possibilities and protection against penetration comprising at least a rigi outer shell and an inner portion of energy absorbing material. At least a portion of the rigid outer shell is thin and has a thickness of 0.01-4 mm, preferably 0.1-1.0 mm in order to collapse at a crash and thus absorb energy and that a coated net, coated woven or coated nonwoven material is at least partially provided between the rigid outer shell and the inner portion of energy absorbing material in order to at least compensate for the penetration protection loss due to the thin rigid outer shell.Type: ApplicationFiled: September 6, 2005Publication date: February 16, 2012Applicant: POC SWEDEN ABInventors: Stefan Ytterborn, Jan Woxing

Publication number: 20120017357Abstract: There is provided a helmet with an improved cradling function and fitting comfort, while also making the helmet easier to put on or take off. The invention comprises an attaching member and a cushion member. The attaching member has a base member mounted in contact with a shell, and a form-maintaining member disposed at an inner lower section of the base member, there being a space left with respect to the base member. The form-maintaining member, while simultaneously keeping a surface corresponding to the cushion member in a profile following the cheek to the chin portion of a wearer, causes the space to contract as a result of being outwardly displaced in the thickness direction in response to greater-than-normal force applied when a helmet is put on and taken off; and, following the displacement that causes the space to contract, is restored so as to return to an original location under normal circumstances, and kept there.Type: ApplicationFiled: September 30, 2010Publication date: January 26, 2012Inventor: Michio Arai
