Problems solved by technology

While suitable for the intended use, such shock absorbing material is insufficient to protect a wearer against the shock wave from explosive devices, such as encountered in military-style helmets.
Although the movable pad systems provide superior shock cushioning to conventional closed-cell foam, the pads may slip during use.

Embodiment Construction

[0012]The particular embodiment of the invention which is disclosed herein has been designed with an overall configuration intended for fitting generally within the shell of various makes of military helmets, though it should be understood, of course, that the liner insert of this invention may be specifically configured to fit within various kinds and makes of helmet shells. Referring now to FIGS. 1-4, the helmet liner insert of this invention, shown generally at 10, also referred to herein as a cushioning and head protecting liner insert for the inside of a shell in a helmet, includes, three main components. Centrally located in helmet insert 10, as one of these three components, is a two-piece load-cushioning structure 12. This structure is made up of fore-and-aft cushioning elements, 14, 16, respectively.

[0013]Additionally included in liner insert 10 of the invention, as second and third components, are, respectively, (a) an outer covering 18, e.g., over the outer surfaces of th...

Abstract

A cushioning and head-protecting liner insert for the inside of the shell in a helmet includes fore and aft cushioning elements each formed of an expanse of a non-springy, acceleration-rate-sensitive, viscoelastic material, with each element possessing, throughout, a uniform thickness which is the same as that possessed by the other element, and with the two elements having edges which are disposed edge-to-edge, but slightly spaced, adjacent one another along a single, continuous, arcuate, reverse-bend line which sweeps from one lateral side of the rear of the insert, at a location spaced laterally from the insert's fore-and-aft extending, laterally central plane, through and over the crown of the insert, to a mirror-image, spaced location on the opposite lateral side of the rear of the insert.

Description

RELATED APPLICATIONS[0001]This Application is related to U.S. Provisional Patent Application Ser. No. 61 / 195,459 for Helmet Liner with Improved, Seam-Position-Enhanced, Rear-Sector Load Management, filed Oct. 6, 2008, from which this Application claims priority. The full contents of that Application are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to a specially constructed load-cushioning and head-protecting liner insert, or liner, for use inside the shell of a helmet, such as the shell of a military helmet.BACKGROUND OF THE INVENTION[0003]A number of styles and configurations of helmet liners are known. The simplest form is the closed-cell foam used on the inside surface of motorcycle and bicycle helmets. While suitable for the intended use, such shock absorbing material is insufficient to protect a wearer against the shock wave from explosive devices, such as encountered in military-style helmets.[0004]One form of military-style helmet liner...
