Figure 9 is an enlarged fragmentary perspective view of a sweatband according to the invention, parts being cut away and shown in transverse, vertical section.

Referring specifically to the drawing, wherein like reference characters have been used through out the several views to designate like parts, and referring at first to Figure 1, It designates generally any suitable helmet having a crown portion or shell 1 l and a brim portion l2.

To space the shell II from the head of the wearer, there has been provided a helmet suspension such as the sweatband l3 and a cradle generally indicated at l l. It is to be understood that the helmet suspension may be of any suitable form, whereby the structures shown and described are illustrative only. With this in view, the sweatband [3, see Figure 9, may comprise a body 15 of any suitable cushioning or absorbent material such as felt or sponge rubber. The inner surface of the body [5 is covered with a strip it of any suitable material, such as leather, plastic or the like which also may overlie the upper edge of the body l5, as at I1, and the upper portion of the outer surface of the body l5, as at l3. The outer surface of the body I5 may be covered by a strip IQ of any suitable material, the lower edge of which may be secured to the body in any suitable manner as by the stitching 20. The upper edge of strip 19 may underlie the down-turned edge l8 of strip I5 and be secured thereto and to the body I5 as by the stitching 2|. Preferably, the outer covering strip I9 is formed with a plurality of pairs of horizontally aligned lacing eyes 22 which may be lined with eyelets 23. The purpose of the eyes 22 will be apparent hereinafter.

By way of example, the cradle IA, illustrated in Figures 1-5 and 7 or the cradle M of Figure 6, comprises a plurality of substantially identical cradle straps 24, the upper ends of which are formed to provide tunnels 25 for a flexible loop 26 whereby the upper ends of the straps are connected together. The lower ends of the straps 24 are each formed with a pair of horizontally aligned lacing eyes 21 or other equivalent attaching means, the purpose of which will be apparent hereinafter.

Figure 8 illustrates a modified form of cradle strap wherein a strap 24 is doubled on itself to form a tunnel 25' at the doubled end. The lower ends of the strap 2Q may be hemmed as at 28 and connected together by eyelets 29 providing lacing eyes 27. Obviously other forms of cradle and/or cradle straps may be utilized.

To support the sweatband l3 and cradles l4 and I4, there has been provided an elongated flexible member 30 which is connected to the shell H of the helmet ID in any suitable manner so as to provide an endless series of chords or chordal portions 3! around the interior of the shell H. The member 30 may be a band or a lace. In the form illustrated the member 30 is a lace and is connected to the shell II by being laced through a plurality of pairs of lacing eyes 32 formed therethrough or other equivalent connecting means. It should be noted that the pairs 1 of lacing eyes are not necessarily uniformally spaced from each other whereby some chords 3! may be longer than others. Obviously, such spacing could be uniform if desired.

While it would be possible to accomplish one purpose of the invention by mounting the fieXible member 38 so as to achieve the end-to-end chord arrangement of the Scholl et al. and Riddell patents, supra, I prefer to anchor the flexible member with a series of loops having crossing ends wherein the bights 33 thereof are anchored to the shell H and the crossing ends form the chords 3|. Thus, the ends of each chord 3| overlap the adjacent ends of both adjacent chords 3| to provide continuous working portions of the member 30 which are spaced from the shell ll. Such working portions comprise the portions of each chord 3| which are between the intersections with adjacent chords. Moreover, it is preferred that alternate chords 3| lie wholly above intermediate chords so that upward flexing of such alternate chords will not be impeded by engagement with such intermediate chords. Conversely, this arrangement serves to retard upward flexing of such intermediate chords.

The foregoing structure permits the flexible member 30 to be connected to the sweatband l3 and to the lower edges of the cradle l4 in a variety of ways to achieve different degrees of resiliency or flexibility in the support. Some of such ways are illustrated in the drawing.

In Figure l, for instance, the lower ends of the cradle straps 24 are laced to certain chords 3! which are also laced to the sweatband l3, which may be laced at additional points to the member 30 as well.

Figure 5 shows an arrangement wherein the straps 24 are laced to chords 3! which lie between chords 3! which are laced to the sweatband [3. Figure 6 is to the same effect although there the number of cradle straps 24 is such that every alternate chord supports a cradle strap while every intermediate chord is connected to the sweatband. In all arrangements where the cradle is connected to a plurality of chords the upward flexing of the cradle can be enhanced by connecting the same to chords which lie wholly above adjacent chords (Fig. 5); retarded by connecting the cradle to chords lying wholly below adjacent chords (Fig. 6); or a mixed effect can be achieved as in Figure 1, whereby the rearmost supporting chords 3! are freely upwardly flexible while upward flexibility of the foremost supporting chord is retarded. Further modifications of the arrangement are obvious.

It should be noted also that the laced connection illustrated in Figures 1, 5 and 6 is a sliding connection whereby full advantage of the flexible support may be taken without binding o buckling of the straps or sweatband.

Figures 2, 3 and 4 illustrate three additional ways of connecting the cradle M to the shell H. Thus, in Figure 2, a cradle strap 24 is relatively tightly connected to the shell II by being laced to the bights 33 of two adjacent loops of alternate chords 3! A slightly looser or medium tight connection is achieved in Figure 3 where the strap 24 is connected to one bight 33 and to an adjacent chord. A still looser or medium loose connection occurs in Figure 4 where the strap 24 is laced to two adjacent chords. The most flexible or resilient connection occurs, of course, where each strap 24 is connected to a single chord 3| as in Figures 1, 5 and 6.

However, the connection between the cradle I 1 and the shell ll may be of different degrees of tightness or resiliency at different points around the shell. For example, in Figure 7, one of the cradle straps 24 is loosely connected manner disclosed by Figure 3. Obviously, further variations utilizing these connections, the tight connection of Figure 2 or the mediumloose connection of Figure 4, will. occur to those skilled in. the m whereby iti thought tobe unnecessary to specifically describev them or illustrate them in the drawing.

It is to be notedthatit, is unnecessary to.con nect the sweatband I3 orcradle 43110 every ,chord 3150f the flexible member 39. For instance in Figures; 1, 5 and 7, certain chords 3] are not connected to eithersweatbandlor cradle. N evertheless, such chords 31' are locatedto engage the sweatband is with a shock absorbing engagement when the necessity arises. However it is contemplatedthat the sweatband l3 will be pro vided with a suflicient number of ,pairso'i lacing eyes 22 orlother connecting means which are so locatedas to permit the attachment of the sweatband to any or ever-y chord 3| or 3| if desired. In like manner, any usablenumber of cradle straps 24 may be provided or even a cradle wherein the lower ends of the straps are joined together by a band (not shown) in which any desired number of pairs of lacing eyes 2.? are formed, whereby the cradle also could be connected to any or all of vthechords.

Obviously, the device of the invention is capable of great flexibility in use tomeet specific needs. Moreover, further variations in tightness or resiliency may be achieved by tightening or loosening the flexible memberii] which may be a lace with the ends tied together. Likewise, where the member. 26, which connects the upper ends of the cradle straps 24, is a lace, adjustment of such straps is possible by loosening or tightening such lace. Diirerent head sizes may readily be obtained merely by utilizing a plurality of differently sized sweatbands I3 or by utilizing a single-size band which is adjustable .as to size in any of a number of well known ways.

Thus, while I have shown and described What is now thought to be the preferred embodiments of the invention, it is to be understood that the same is susceptible of other forms and expressions. Consequently, I do not limit myself to the 1.
