...Giannina Bianchi; Othmar Brügger; Steffen Niemann; Mario Cavegn The aim of this study is to examine the correlation between helmet use and on-slope ski conduct. During the months of February and March 2009, eight trained interviewers asked 1550 skiers and snowboarders at 20 ski resorts...

... of helmet liners, like expanded polystyrene (EPS). The experiments involved dropping a certified size E headform vertically onto a flat, solid anvil. Elastically deformable and resilient VN foam outperformed EPS during all impacts. Incorporating a viscous aqueous solution of 30 % by weight glycerin into 3/8...

...Amber Giacomazzi; Terry Smith; Robert Kersey This paper reports on the results of a study to determine the protective characteristics of ice hockey helmets when tested using two different methodologies. The first methodology involved a traditional monorail drop impact test commonly used in North...

...P. Rousseau; A. Post; T. B. Hoshizaki The objective of this study was to quantify the ability of hockey helmets to manage peak angular and linear acceleration of the center of gravity of a Hybrid III headform at six impact locations and three velocities (5, 7, and 9 m/s). The method was intended...

...L. Lamb; A. Post; T. B. Hoshizaki Currently, ice hockey helmet technologies are based mainly around foam energy absorbers. There is a need in the head protection industry for improved designs, capable of protecting the brain under a wide range of impact conditions. Air chambers are new, thin-walled...

...David J. Pearsall; Patrick M. Dowler After manufacture and before retail, ice hockey helmets must pass safety standard tests based primarily on multiple impacts at several global sites to receive certification. Unknown is the effective “shelf life” of these products; that is, do material...

... conditions. In this study, we characterized the fall kinematics and quantified head velocity in order to evaluate the helmet energy management requirements associated with a back-edge trip. Digital high-speed video recorded at 500 frames per second was used to quantify the snowboarder’s head kinematics: (i...

... as other age groups to sustain injuries to the head, face, and neck. While helmets have been shown to reduce the overall number of head injuries for the pediatric population, some members of the skiing and medical communities have indicated that pediatric helmets may increase the likelihood of neck...

... by the “opposite-edge phenomenon” where the snowboarder falls backward and contacts the occiput. In order to determine if the use of skiing helmets would reduce the likelihood of head injury associated with catching an edge snowboarding, we conducted a two-part study. In the first part, we measured the speeds...
