ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to a head-protective helmet including a geodesic dome. Further, this invention relates to a geodesic dome in combination with other elements comprising a head-protective helmet.
Numerous head-protective helmets are known to the art, such as, by way of example and not by way of limitation, firefighters, helmets, industrial helmets (sometimes referred to as hard hats), fighter pilot helmets, and other military helmets.
An example of a firefighter's head-protective helmet is disclosed in U.S. Pat. No. 5,044,016 entitled PROTECTIVE HELMET ASSEMBLY INCLUDING RELEASABLE HEAD RETAINING ASSEMBLY, patented Sep. 3, 1991, Christopher E. Coombs, inventor. This patent is assigned to the same assignee as the present application, and this patent is hereby incorporated herein by reference as if fully reproduced herein.
FIGS. 1 and 2
of this incorporated patent are reproduced herein as
FIGS. 1 and 2
. Referring to
FIG. 1
, the head-protective helmet is indicated by general numerical designation
10
and includes an outer shell
12
, sometimes referred to as the hard shell, an attenuation liner assembly
14
, a brim
16
circumscribing the outer shell
12
, a pivotally mounted transparent visor
18
, a chin strap
22
including a chin cup
24
. The attenuation liner assembly
14
,
FIG. 2
, includes a non-resilient foam liner
26
, sometimes referred to as an inner impact cap, frictionally fitted within the outer shell
12
, with the exterior of the foam liner
26
corresponding to the interior surface of the outer shell
12
. The foam liner or inner impact cap
26
is retained frictionally within the outer shell
12
with such frictional retention being augmented by the cooperating patches of hook and loop fastener material generally indicated as
40
in FIG.
1
. The non-resilient foam liner
26
, or inner impact cap, is for absorbing force or energy applied to the helmet
10
by being compressed which attenuates force or energy that would otherwise be transferred to the head of the wearer of the helmet upon, for example, a falling object striking the head-protective helmet
10
. The outer shell
12
typically is made of a hard plastic such as a suitable high temperature thermoset which may be filled with glass or other fibers for increased strength, and the inner impact cap
26
typically is made of a suitable non-resilient or compressible material such as, for example, rigid polyurethane foam.
While the head-protective helmets known to the art, such as the firefighter's helmet disclosed in the incorporated patent and shown in
FIG. 1
, have worked well for their intended purpose, there still exists a need in the head-protective helmet art for a head-protective helmet providing increased protection against force or energy that would be applied to the head of the helmet wearer, such as by falling objects. Also there is a further need in the head-protective helmet art for a head-protective helmet providing increased resistance against a falling object penetrating the helmet and striking the head of a wearer of the helmet.
SUMMARY OF THE INVENTION
It is the object of the present invention to satisfy the foregoing need in the art.
A head-protective helmet satisfying such need and embodying the present invention is a head-protective helmet comprising a geodesic dome. A further feature of the present invention is the geodesic dome in combination with other elements comprising a head-protective helmet.
