Embodiment Construction

[0064] Attached Image 6 and 7 A compressible shock absorbing compressible unit 10 comprised in accordance with the present invention is shown in FIG.

[0065] exist Image 6 and 7 In the exemplary embodiment of the present invention, the unit 10 is made of a thermoplastic material such as a thermoplastic elastomer (TPE) material, formed as a thin-walled hollow housing 12 having a top wall 14a and a bottom wall 14b therethrough and a hole 16. The sidewalls 18 of the unit 10 are oriented in a quasi-vertical manner such that they provide an initial resistance to impact on the unit 10, but then strategically bend outward to allow the passage of fluid (in this example air) in the unit 10 through the Hole 16 vents and manages the remaining impact, as indicated by air flow arrow 20 . The elastic properties of the thermoplastic material from which unit 10 is made, combined with the backfilling of air via holes 16, allow unit 10 to quickly return to its original shape after impac...

Abstract

An impact-absorbing protective structure comprises one or more compressible cells. Each cell is in the form of a thin-walled plastic enclosure defining an inner, fluid-filled chamber with at least one small orifice through which fluid resistively flows. Each cell includes an initially resistive mechanism that resists collapse during an initial phase of an impact and that then yields to allow the remainder of the impact to be managed by the venting of fluid through the orifice. The initially resistive mechanism may be implemented by providing the cell with semi-vertical side walls of an appropriate thickness or by combining a resiliently collapsible ring with the cell. After the initially resistive mechanism yields to the impact, the remainder of the impact is managed by the fluid venting through the orifice. The cell properties can be readily engineered to optimize the impact-absorbing response of the cell to a wide range of impact energies.

Description

technical field [0001] The present invention generally relates to impact energy management methods and systems. More specifically, the present invention relates to impact energy management methods and systems designed to protect an impacted object or body from damage from impact with the ability to be easily tailored to provide optimal impact attenuation over a wide range of impact energies The properties of the response. Background technique [0002] A. Physical properties of colliding objects [0003] An object in motion has kinetic energy (KE), which is a function of the mass (m) and velocity (v) of the object, expressed by the following formula: [0004] KE = 1 2 mv 2 - - - ( 1 ) [0005] When the object collides with another object, energy conversion occurs, producing a force (F). The transm...
