HELMET COMBINATION SUSPENSION Filed Jan. 26, 1968 2 Sheets-Sheet 2 United States Patent US. Cl. 23 8 Claims ABSTRACT OF THE DISCLOSURE A helmet assembly in which the head suspension system is arranged to be adjustable to accommodate various head shapes, and in which shock and sound control padding is mounted for removability to allow using different sizes and shapes of padding to achieve comfort and protection.

This invention relates to protective helmets and is especially directed to improvements in helmets of the general type used by football players.

There are a number of problems which have persisted for some time in the construction of helmets, especially helmets of the type used by football players. One of the more important of these problems is the arrangement of suspension means by which the helmet shell is mounted on the head of the player. Practically no attention has been given to the fact that head shapes vary from player to player and there is practically no suspension assembly that will properly position the helmet shell for maximum protection on everyone. Another important problem is the poor location and mounting arrangement for padding so that there will be achieved more than adequate shock absorbing means between the helmet shell and the players head, and the lack of means to control the propagation of sound within the helmet shell.

One of the main objects of this invention is to provide a suspension system and sound control padding so as to overcome the above mentioned problems.

It is also an important object of this invention to provide helmet suspension means that can be selectively adjusted to accommodate practically all head shapes and still maintain the helmet in a comfortable position.

Still another important object of the present invention is to provide a protective helmet with detachable side pads so that protection and control of sound within the helmet is achieved.

It is a further object of the present invention to provide improved suspension means for mounting the protective helmet on the head of a football player and to assemble the suspension means in at least two independent parts and to interconnect the parts for cooperation.

One preferred embodiment of the present invention includes a unitary helmet shell provided with a crown portion, the usual ear covers and cheek extensions, and removably mounted front and rear suspension assemblies, each of which is provided with a plurality of suspension straps. The preferred embodiment also includes means for adjustably interconnecting the suspension straps so as selectively to lengthen or shorten the straps in a manner to accommodate a variety of head shapes. The preferred embodiment, furthermore, includes detachable side pads which extend over the temples and above the ears in a manner to absorb shock from side blows and also to control cross travel of sound within the helmet shell.

In view of the statement of the foregoing objects and a brief description of the preferred embodiment of the 3,486,169 Patented Dec. 30, 1969 present invention, reference will now be made to the several views in the drawings, wherein:

FIG. 1 is a side elevational view of the presently improved helmet emboding the various features to be presently described;

FIG. 2 is a greatly enlarged sectional View of the helmet shown in FIG. 1, the view being taken along the line 2-2;

FIG. 2A is a view similar to FIG. 2 to show one alternate arrangement for the suspension harness; but other arrangements are, of course, possible;

FIG. 3 is a transverse sectional view of the presently improved helmet taken at least 33 in FIG. 1;

FIG. 4 is a greatly enlarged fragmentary view of a typical arrangement of the suspension means; and

FIG. 5 is a greatly enlarged view of a side pad showing the herein preferred means for adjustably and movably mounting the pad in protective position.

Reference will now be made to the several views in the drawing where it can be seen that the helmet comprises a one piece molded shell 8 made of any suitable material, such as laminated fiber glass, and conformed so as to provide a crown portion, a front edge 9 which fits well down over the forehead of the wearer and a rear edge 10 which extends down over the neck of the wearer to protect the cervical region. The helmet 8 is also provided with the usual ear and cheek extensions 11, and each of these extensions is provided with a sound admitting opening 12.

Turning now to FIGS. 2 and 3, it can be seen that the shell 8 is provided on the interior with a pair of suspension harnesses, a suspension harness 13 being adapted to conform to the front of the wearers head and the suspension harness 14 being adapted to accommodate the rear portion of the wearers head. The front suspension harness includes a main strap 15 which extends from one end portion 16 to an opposite end portion 17. The end portions 16 and 17 respectively are connected by removable threaded

elements

18 and 19 to the shell 8 in a manner that will be presently described. In addition the main strap 15 is also secured at opposite sides of the front portion by threaded

elements

20 and 21 which pass through openings in the helmet shell 8 and engage clamp plates 22 which are of identical configuration :and will be presently described. The portion of the main strap 15 between the clamp plates 22 is secured in position by another clamp plate 24 removably held in position by a threaded element 25 passing through the front wall of the shell 8. The suspension strap 15 cooperates with a chordal strap 23 directed across the forehead portion so that a forehead pad 26 may be mounted thereon to prevent contact of the rough material of the strap with the forehead of the player.

The rear suspension harness includes the main strap 27 secured by its

ends

28 and 29 by threaded

means

30 and 31 which pass through the shell 8, and between its

ends

28 and 29 the strap 27 is also removably connected to the shell by clamp plates 22 held by threaded elements 32 and 33, and still further by a rear clamp plate 34 having its threaded attachment element 35 mounted in the shell. The head of the wearer is prevented from engaging the interior rear portion of the shell 8 by the chordal strap 37 which has its

ends

38 and 39 secured to the main strap 27 spaced from the clamp plates 22.

As can be seen in FIGS. 2 and 3, and in some minor detail in FIG. 4, the front suspension harness is provided with a plurality of suspension elements 40 and the rear suspension harness is provided with a plurality of suspension elements 41. The

respective elements

40 and 41 have their outer ends secured to the

suspension harness

13 and 14 respectively while the inner ends are directed toward a central crown area and are joined by a cord 42 which is laced through the inner end loops of the

elements

40 and 41 and secured with a tie 43. The

respective elements

40 and 41 are stitched or tacked at 44 and 45 (FIG. 3) so that each thereof will be provided with a space through which the cord 42 may be strung either at the end (as shown) or at one or two places inwardly of the end. For example, (FIG. 2A) the cord 42 may be looped through the front elements 40 between the

stitching

44 and 45 so as to shorten elements 40 and accommodate the forehead suspension harness to a head shape where the forehead is backwardly sloped. On the other hand, if the players forehead is very prominent and the rear portion of the head is sloped, the cord 42 may be placed in the elements 41 either between the

stitching

44 and 45 or inwardly of the stitching 45 so that the suspension system Will accommodate that particular head shape. In like manner the cord 42 may be inserted through element openings in certain of the

harness elements

40 and 41 on either side to take care of head shapes that are not symmetrical from side to side.

Turning now to FIG. 4 it can be seen that a typical suspension harness end portion includes for the rear suspension harness 14 the main strap 27 provided with one end 28 having a grommet eye 28a positioned therein in order to receive the threaded element 30 which will be inserted through the body of the shell 8 and through the opening in the grommet eye 28a for threading connection with a socket element (later to be described in connection with FIG. Inwardly of the end 28 the main strap 27 provides an anchorage for the outer ends 4111 and 41b of one of the loop elements 41. Proceeding still further away from the end 28, the main strap 27 is securely anchored to the shell 8 by a clamp plate 22 which has a threaded opening 22a therein to receive the threaded element 32 which passes through the shell 8. The clamp plate 22 is provided with suitable longitudinal beads for purpose of stiffening the same. To the left of the clamp plate 22 as seen in FIG. 4 the main strap 27 supports the ends 41a and 41b of another suspension loop 41 and also supports a piece of Velcro material. The View of FIG. 4 is typical of the arrangement of end portions of the front and rear suspension harnesses. The Velcro material is set forth in United States Patent No. 2,717,- 437 issued Sept. 13, 1955 to De Mestral. The Velcro material is available from John Boyle and Company, Incorporated of New York City.

Turning now to FIG. 5, and with reference to FIGS. 2, 3 and 4, it can be seen that a typical side pad 45 includes a body of shock absorbing foam material shaped with a plurality of indentations 46 in order to allow the body to shape itself to the temple portion of the wearers head. The outer side of the pad 45 is provided with a pair of threaded sockets 47, each socket 47 being attached to a mounting patch 48. The patches 48 are then adhesively or otherwise secured to the surface of the pad 45. The opposite bevelled end portions of the pad 45 carries a cooperating section of VELCRO material 49 such that when the pad 45 is mounted so that, for example, the threaded

elements

18 and 30 enter the sockets 47, the Velcro portion 49 on the opposite ends of the pad 45 will engage the cooperating Velcro elements 50 (see FIG. 4) and maintain the end portions of the pad in position. It is, of course, appreciated that each pad 45 may be adjustably mounted by joining the Velcro

pads

49 and 50 in any desired position prior to moving the central portion of the pad up or down to match sockets 47 with 18 and 30 and/or 19 and 31. Alternatively the ends can be adjusted after the threaded elements engage sockets 47.

Having now described the structural features of the presently improved helmet suspension and padding, it should be easily appreciated that the suspension harness assembly can be adjusted and shaped to accommodate substantially any head shape or configuration so that the helmet may be individually tailored to the needs and comfort of the wearer. It can also be appreciated. in view of the disclosure in FIGS. 2 and 3 that the side pads 45 are so located that the wearers ears are outside of the sound chamber within the helmet shell 8. In other words, the pads 45 prevent sound revibration within the helmet shell 8 and thereby prevent stadium roar from bothering the hearing ability of the wearer. This is an important feature which has not heretofore been fully realized by manufacturers of helmets. The side pads 45 may be quite easily removed and replaced with various thicker or thinner pads depending on the comfort of the wearer, and the application of the Velcro material to the ends of the pads 45 permits some degree of up or down adjustment of the pad ends to suit the comfort of the wearer.
