Description

Oct. 27, 1964 M. T. MARIETTA 3,153,792
TWO PART DETACHABLE LINER FOR SAFETY HELMETS Filed July 9, 1963 INVENTOR.
United States Patent O 3,153,792 TWO PART DETACHAELE LNER FR SAFETY HELMETS Michael T. Marietta, 5533 University Bird., lallas, Tex. Filed July 9, i963, Ser. No. 2l/3,6% 4 Claims. (Cl. 2 3) This invention relates to safety helmets for protecting the head of the wearer who may be engaged in various activities where protection is required, such for example as in football, automotive racing, or even in the case of mill or construction workers.
As is well known, the helmet comprises an outer shell, usually of light molded material and requires an interior lining to comfortably hold the shell in place and also to absorb the shock of blows or impact with other objects.
The shell usually outlasts the interior structure which in many cases, is used by several dilerent persons. For sanitary reasons and comfort, it is desirable to make the inner lining, which usually includes a sweat band, detachable. The lining alone, however, is not sufficient to protect the important areas of the head from as much shock or as many blows as possible.
Accordingly, the present invention has primarily in view a preabricated integrated two-part lining assembly which may be readily snapped in place within the shell and readily removed. One element of this assembly includes a reticulated or cage-like series of tapes including a horizontal two-ply sweat band and vertically disposed strips of fabric webbing secured to the outer ply and adjustably looped about a crown piece having a central opening. These strips may be made adjustable to enable the unit to be placed in helmets of dierent depth. The other element of the assembly is in the form of a reticulated foam rubber cushion including a compressible plug to enter said opening in the crown piece and a plurality of spaced leg portions having trident shaped ends to detachably interlock with the sweat band.
With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, hereinafter more fully described, illustrated, and claimed.
A preferred and practical embodiment of the invention is shown in the accompanying drawing, in which:
PEG. l is a side elevation of the improved liner unit.
FlG. 2 is a top plan view.
FlG. 3 is a partial bottom plan View.
FIG. 4 is a fragmentary perspective View of a portion of the cushion element to better show the trident end of one of the spaced cushion arms.
FG. 5 is a detail cross sectional view taken on the line S-S of FIG. 2.
FIG. 6 is a View illustrating the application of the invention.
Similar reference characters designate corresponding parts throughout the several i'igures of the drawing.
As will be seen from the drawing, the liner assembly includes as a iirst element the cage-like webbing or reticulated webbing having an annular sweat band including an inner ply 1 and an outer ply 2, the same being connected as for example by stitching together at regular intervals, as shown at 3, thereby to provide a series of pockets 4. At the middle portion ot each pocket there is secured to the outer ply 2 by a threaded nut receiving grommet 5 or the like, a series of vertical cotton webbing strips 6 whose upper ends are looped through the slots '7 in a suitable leather or like disc 8.
The vertical strips 6 are provided with a series of separable snap fasteners 6a in order to make them longitudinally adjustable when desired. in other words, by
Fice
lengthening or shortening the strips 6 through re-positioning the fasteners 6a, it is possible to change the distance between the disc S and the two-ply sweat band .1r-2.
The disc 8 is surmounted by a cushion C having peripheral recesses 5a to receive the portions oi the vertical strips which project through the slots 7 and has a central opening 9 intended to receive the plug portion ll) of an inner foam rubber spider-like or reticulated cushion designated generally as ll, and which constitutes the second element of the assembly. The body portion of the cushion ll having the plug lil is detachably interlocked with the opening 9 of the disc 3, and is also provided with a plurality of radially disposed arms l2 each having trident shaped terminal portions 13, which provide separate iingers to detachably interlock with the sweat band.
rThe arms l2 parallel the inner side portions of the strips 6 and the trident terminal portions include a medial prong ld which ts into and engages with the pockets 4 between the inner and outer plys l and 2 of the sweat band while the outer prongs l5 engage and overlie the outer sides of the outer ply 2.
The cushion lining il of sponge rubber has a crown perforated for ventilation, medially provided with a compressible locking plug l@ which lits into the opening 9 of the leather disc 8 while the arms l2 cover or mask completely the inner faces of the vertical webbing strips 6 when the trident terminal portions are detachably interlocked with the outer plys 2 as shown in FIGS. l3 inclusive.
When it is desired to sanitize both elements of the entire two-part liner assembly, it is readily detached from the shell S of the helmet. That is to say, the foam rubber cushion il, l2, i3, i4, l5 is detached from the disc 8 by pushing the plug il) through the opening 9. The trident shaped terminal portions of the cushion may be readily disengaged from the two-ply sweat band by simply lifting the medial portion of each arm 12 to pull its center prong ld out of its related pocket 4 and at the same time sliding the outer prongs 15' across the face of the outer ply Z of the sweat band. When all of the trident end portions are disconnected from their related portions of the sweat band, then the entire cushion can be removed and a new one substituted when desired.
As previously indicated, the outer ply 2 of the sweat band is provided with a grommet 5 or the like intended to receive a threaded nut, not shown. This nut cooperates with a threaded screw, also not shown, piercing the shell at an appropriate point and having its slotted head eX- posed at the .surface thereof. When removing the sweat band from the shell, the screw, is removed from the nut and the shank of the screw releases the grommet 5 to permit removal of the entire reticulated webbing. In replacing the sweat band, this procedure is reversed.
