United States Patent Qthee 3,082,427. Patented Mar. 26, 1963 3,082,427 SAFETY HELMET Ted Zhihowski, Detroit, Mich., assignor to Joseph Buegeleisen Company, Detroit, Mich. Filed May 19, 1960, Ser. No. 30,277 3 Claims. (Cl. 23)
This invention relates to safety helmets and more particularly to a unitized liner formed as the interior of the shell of a safety helmet.
Safety helmets are generally formed of an exterior inverted bowl-like shell shaped to fit over the human head and some kind of support means within the shell to support the shell upon the head. The interior support or lining generally has been formed out of a number of separate pieces which were individually secured to the shell. These are expensive and difiicult to assemble and thereby raise the overall cost of the helmet. Also at times, these pieces fail to work together as a unit to protect the wearers head to the maximum degree possible.
Thus, the object of this invention is to form a safety shell having an interior liner formed as a unit, with all the parts secured together and simply attached to the shell in one simple operation by means of fitting the bottom edge of the shell into a single channel of the edge band.
A further object of this invention is to form a single unit liner which is so padded as to flexibly package the human head and distribute any load or blow upon the helmet uniformly to the human head to thus prevent damage to the head.
These and other objects and advantages of this invention will become apparent upon reading the following description of which the attached drawings form a part.
In these drawings:
FIG. 1 is a cross-sectional elevation of the shell and liner forming the helmet.
FIG. 2 is a bottom view taken in the direction of arrows 22 of FIG. 1.
MG. 3 is an enlarged cross-sectional view of the interior liner assembly, and
FIG. 4 is a view of a portion of the padded strip, per se, as if taken in the direction of arrows 44 of FIG. 3.
FIG. 5 shows a modification of a portion of the liner strip before assembly.
FIG. 6 is a cross-sectional view taken on arrows 6-6 of FIG. 5.
As shown in the drawings, and particularly FIG. 1, the helmet 10 is formed of two separate units, namely, a shell 11 and an interior liner assembly 12. The shell is a thin wall, inverted, bowl-shape having an open bottom defined by a bottom edge 13. It is preferably formed of a rigid material having great strength, such as a fibrous glass reinforced plastic resin which is rigid and capable of sustaining heavy loads without breaking. Various types of resins are well-known in the art for this purpose and hence, no description of the particular plastic selected is needed, it being sufficiently understood that the shell is of great strength and is formed of a single thin wall.
The liner assembly 12 is formed of a number of sep arate elements which are joined together prior to assembly with the shell. These elements include a padded liner strip 15 (see FIGS. 3 and 4) which is formed of an elongated, relatively narrow strip of cloth or clothlike material 16 whose opposite ends are joined together to form an endless band. It has a bottom elongated edge 17 and a top elongated edge 18.
As shown in FIGS. 4 and 5, the strip 16 is overlapped on its outer face with a pair of elongated strips, namely, upper strip 21 and lower strip 22, which together form pockets 20. The upper strip 21 has a top edge secured by continuous stitching 23 to the top edge 18 of the strip 16. its bottom edge is spaced above the center of the strip 16. The lower strip 22 has its bottom edge stitched continuously at 24 to the bottom edge 17 of the strip 16.
it can be seen in FIG. 4, that the free edges of the strips are spaced apart so that together they form pockets wherein the openings of the pockets are at the center of the strip 16 and are relatively wide. The individual pockets 20 are further defined by vertical rows of stitches 26 which rows are spaced apart a sufiicient distance to form one pocket between each pair of rows 26.
Within each pocket is a slab 27 formed of a resilient, relatively thick material such as sponge or foam rubber or foamed polyethylene or some such similar resilient but relatively light weight material. The slabs are fitted into their respective pockets through the center openings thereof and may be flexed within their pockets because of the freedom given by the wide center openings. Also, the slabs may be easily removed and replaced when desired.
A plurality of spaced apart loops 28 are stitched to the top edge 18 of the strip 16. The loops may be formed of cloth and are formed to receive a drawstring 29 for gathering the top edge 18 together.
Means for securing the padded liner strip 15 to the shell is provided in the form of an elongated edge band 30 shaped in cross-section as a double channel (see FIG. 3) having an outside channel 31 and an inside channel 32 with a common leg 33 between the two channels and an inside leg 34. The bottom edge 17 of the liner 15 is stitched continuously by one or more rows of stitches to the inside leg 35. The ends of the band 30 are joined together, as for example, by a suitable adhesive, so as to form a continuous band.
An elongated, relatively thick, sheet 36 of a resilient material, such as foamed polyethylene or sponge rubber or the like is arranged with its bottom edge 37 fitted into the inside channel 32. The sheet 36 is of sufiicient length to surround the outside padded face of the liner strip 15. A suitable adhesive may be used to hold the bottom edge 37 within the channel 32.
After the liner assembly parts are joined together as mentioned above to form a complete unit, it is ready for attachment to the shell. Prior to attachment the draw spring 29 may be passed through the loops 28 and its ends tied together in order to gather the loops together and thus gather the top edge 18 of the liner strip 15 together at a location just below the top of the shell.
Thereafter, the shell bottom edge 13 is inserted into the outside channel 31 of the edge band 30 and is held therein by means of a suitable adhesive.
Thus, the final assembly consists merely of pushing the bottom edge 13 of the shell into the outside channel 31 and this can be very easily accomplished. Where the inside liner is damaged or the shell is damaged and it is desired to replace one or the other, they can be disassembled simply by tearing them apart and replacing either the shell or the inside liner unit, as the case may be.
It can be seen, that the sheet 36 is arranged in face to face contact against the inside face of the shell wall and is positioned between the shell and the padded face of the liner strip 15.
The edge band 30 is preferably formed of a resilient material such as rubber or a resilient plastic. In case of a blow to the helmet, it serves to act as a spring to absorb the impact as the shell is forced down and the liner is forced up within the helmet. Being resilient, it is spring-like and hence, absorbs a great deal of the shock.
Preferably, a top pad 42 is arranged above the liner assembly in contact with the wall of the shell (see FIG. 1). This pad 42 may be some resilient material such as rubber or foamed plastic or the like, and provides additional protection for the top of the wearers head if a blow to the helmet is hard enough to cause the head to strike the top of the shell.
As can be seen, the shell, while shaped to fit a human head, is considerably larger than the head and wouldnormally. be spaced at considerable distance from the head. The liner strip 15 would actually fit right around the head as if it were an interior hat with the sheet 16 in contact with the head and the padding on the outside.
In case of a shock or blow to the helmet, the strip 15 functions to distribute theload evenly around a wide circumferential band, to thereby squeeze the head circumferentially, and hence, distribute the load and prevent damage to the head. The padding on the outside, that is, the-pockets which are filled with the padding or slabs, cushions and distributes the blow. The resilient sheet 36 also further cushions against the blow as the liner strip 15 may move against one part or another of the shell wall in response to a blow.
FIGS. 6 and 7 show a modified strip 15a, similar to that shown in FIG. 3. Here, a strip 50 is secured to the cloth material 16 and is periodically slitted vertically at 51 to form the openings for the pockets 20a. The pockets are separated -by vertical lines of stitching 21a and are filled with the resilient slabs 27a. Hence, instead of horizontal openings to the pocket as in the case of the modification shown in FIG. 3, the openings to the pockets are in the form of vertical slits.
It can be seen, that the entire liner assembly can be put together prior to inserting it in the shell, and hence, can be easily fabricated on an ordinary sewing machine and requires only a minimum amount of labor to assemble. The liner asembly and the shell are put together simply by placing a small quantity of some suitable adhesive into the outside channel 31 of the edge band 30 and then pressing the shell edge 13 into channel 31.
The small slabs of resilient material within the pockets make it possible to replace any damaged slabs without taking the whole liner apart and throwing it away, and also make it possible to use What might otherwise be scrap material, since small size pieces of foam material normally are not useful for this purpose.
This invention may be further developed within the scope of the following attached claims. Accordingly, it is desired that the foregoing description be read as being merely illustrative of an operative embodiment of this invention and not in a strictly limiting sense.
