protectors will come off accidentally during a game and thus less likely that the entire helmet will also come off prior art helmets include chin straps that are attached to the shell using a single snap fastener often this is a rotatable connection which allows the strap to orient higher or lower with respect to the helmet shell by pivoting at the snap it is advantageous to have straps 34 which can pivot with regard to the shell so that the chin cup 32 can be adjusted to accommodate players having heads of various shapes and sizes if two standard snap fasteners are attached directly to a helmet however and a chin strap is snapped on to both fasteners the strap will not be able to pivot at the connection this is true even if each connection on its own is rotatable consider analogously how a board loosely nailed down at a single point can rotate around the nail while a board loosely nailed down at two points cannot rotate at all thus its is particularly desirable to combine the added connection strength of two snaps with the pivoting ability of a single snap applicant has solved this problem by providing pairs of helmet side snaps u2014 second snaps 54 u2014 on pivoting rotatable snaps set 50 this allows pairs of snaps 54 to pivot or rotate together with respect to the helmet shell 12 this in turn allows the buckles 40 and chin straps 34 attached to the buckles to pivot as well the snaps set 50 may simply comprise a small piece of hard plastic carrying a pair of second snaps as shown in fig1 2 and 6 persons of skill in.
