Abstract
Abstract A suspension for a hard protective hat has a crown piece adapted to overlie the wearer''s head and a plurality of band arms extending outwardly from the crown piece and provided at their outer ends with respective attachment feet adapted to be secured to the hat. Two of the arms extending from the crown piece in opposite directions terminate short of the respective feet and are connected to these feet via respective connecting members each having one end attached to the outer end of the arm and another end attached to the respective foot and each including a ligature entending transverse to the respective arm. These ligatures are of smaller cross section than the arms so that even in very cold weather they are capable of deforming in the longitudinal direction of the arms and imparting resilience to the suspension. Curved stabilizing elements extend from each of the feet to the crown piece and are of smaller cross section than the arms so that these stabilizing arms are first pulled tight and straight before the arms are longitudinally loaded.
