    I claim:1. A helmet shell suspension comprising ceiving cradle having head-engaging straps ends adapted to be attached to a helmet shell to support the shell, tabs having lower ends fastened to the lower ends of the cradle straps and extending therefrom inside the cradle, the outer side of each tab being provided with a plurality of vertically spaced projections, and a headband-supporting member adjacent the inner side of each tab and provided with a pair of vertically spaced transverse slots forming between them a loop extending ’ snugly around the tab between a pair of its said projections, the height of each slot being substantially equal to the thickness of a tab at one of its projections, said tabs being bendable transversely to allow said projections to be pushed through said slots so that said loops ‘° can be adjusted up and down the tabs to permit a headband to be adjusted vertically in the cradle. This invention relates to suspensions for protective helmet shells, and more particularly to those provided with vertically adjustable sweat bands. Whether or not a protective helmet shell suspension is adjustable to accommodate heads of different crown heights, the sweat band may ride too high on the head of a person with a high crown and too low around the head of a person with a low crown. It is therefore among the objects of this invention to provide a hat suspension, in which the sweat band can be adjusted vertically in the lower part of the head cradle, and in which positive means are provided for holding the sweat band at any desired level. In accordance with this invention, a head-receiving cradle has head-engaging straps, the lower ends of which ------- r------o------- ---- _ are attached to a helmet shell to support the shell. Fas- 30 same degree of force. . The teeth prevent the headband tened to the lower ends of the cradle strap are the lower ends of tabs that extend upwardly inside the cradle. The outer side of each tab is provided with a plurality of vertically spaced projections. Adjacent the inner side of each tab is a 1-------loop that extends snugly around the tab between a pair of its projections. Preferably, the projections extend horizontally across a tab and have lower loop-engaging surfaces connected by inclined surfaces to the portions of —------—„----------. the tab above them. The projections therefore positively 40 tany separating from the tabs 12, the upper corners ot tne hold the headband against movement upward in the suspension. However, such upward movement can be effected when desired, by manually pressing the projections through the loops of the headband-supporting members. The preferred embodiment of the invention is illus- , trated in the accompanying drawings, in which Fig. 1 is a bottom or inside view of a helmet equipped with my suspension;Fig. 2 is an enlarged longitudinal section taken on the line II—II of Fig. 1;and Fig. 3 is an enlarged fragmentary side view of the outside of the headband, showing one of the. tabs and the headband-supporting member connected to it. Referring to Figs. 1 and 2 of the drawings, the rigid shell of a protective hat or helmet has a dome-shaped crown 1 surrounded at its bottom by an integral brim 2. Inside of the shell there is a suspension, by which the shell is supported and held in position on the head of a wearer. The suspension includes a head-receiving cradle formed from straps 3 of any suitable material, which extend across the top of the head or are connected at the top by a lace 4. The lower ends of the straps may be fastened in any suitable manner to the lower part of the shell in order to support it. For example, a snap fastener or rivet 5 can be used for that purpose. Disposed inside the lower portion of the cradle is a headband, generally consisting of a backing band 6 and a sweat band 7 joined together at their lower edges in any suitable manner. As shown in Fig. 3, the backing band is provided at opposite edges of each cradle strap with two pairs of vertical slits to form a pair of vertical loops 8, which receive the opposite ends of a headband specifically a head-rewith lower

  3. 3
    A helmet shell suspension comprising a head-re- 5 ceiving cradle having head-engaging straps with lower ends adapted to be attached to a helmet shell to support the shell, relatively stiff tabs having lower ends fastened to the lower ends of the cradle straps and extending upwardly therefrom inside the cradle, the outer side of each tab being provided with a plurality of vertically spaced projections, and a headband-supporting member adjacent the inner side of each tab and provided with a pair of vertically spaced transverse slots forming between them a loop extending snugly around the tab between a pair of its said projections, the height of each
