Corrugated tubular energy absorbing structure

An energy absorbing tubular structure is formed of a molded or extruded polymer. The tube has a quadrangular cross-section with rounded corners. The walls of tube are corrugated with alternating convex and concave corrugations surfaces having a continuous constant radius, preferably with no flat spots. The corrugated walls have a constant thickness. The corrugations progressively deform during impact thereby providing a near perfect square wave force vs. deflection energy absorption curve at any predetermined nearly constant force level. The tube may be filled with polymer foam to vary the impact performance of the structure.

Energy absorbing protective member

A protective member primarily for use as an energy absorbing pad for incorporation into garments to protect the wearer against accidental impacts. The member comprises a putty-like energy absorbing material (2) encapsulated in a flexible envelope (3, 4). The energy absorbing material is normally soft and flexible but changes to become temporarily rigid when an impact force is applied thereto, thereby absorbing the impact energy, the material returning to its normal flexible condition after the impact. The energy absorbing member preferably comprises a series of connected corrugations to increase its energy absorbing properties.
