Energy Absorbing Tube
Our patented O-EA™ tube is uniquely capable of satisfying space constraints while fully meeting regulatory requirements. We provide vehicle occupants with protection during front-impact and side-impact collisions. Current applications include a pedestrian guard and a bumper guard, with countermeasures placed in: roof liners, side rails, pillar trims, knee bolsters, door panels, bumper rails, and bumper fascia.
Product Advantages over other Countermeasures:
- Lowest Cost Solution, typically no-tooling cost and rapid product availability
- Preferred Quality Solution
- Design Flexibility and Easy to Install
- Performs Superbly in Tight Spaces
- Absorbs Energy throughout deformation
- Adds Negligible Weight
- Withstands Temperature Variations from -40 to 110c
- Surpasses HIC, IIHS and LINCAP requirements
- Exceeds OEM Flammability and Fogging requirements
- Compared to Plastics and Foams, our products are completely Recyclable and Green
This LS DYNA simulation shows the dynamic response of a 19x19 mm cross section O-Flex energy absorber impacted by a 10 lbm spherical ball at a speed of 5 mph. The O-Flex energy absorber is mounted to an infinitely rigid background plate. The acceleration vs. time "green" curve is a near perfect "square wave" with low peak acceleration absorbing 100% of the FMVSS 201U head impact energy.
This LS_DYNA simulation shows a 10 lbm FMVSS 201U head form impacting O-Flex 3101 energy absorber at 40 KPH demonstrating a near perfect square response at both high and lower impact velocities confirming test correlations.
This LS_DYNA simulation shows the FMVSS 201U free motion head form in vehicle test. The head form is shown impacting a sport car A-pillar with six O-Flex axial mounted energy absorbers. The six O-Flex energy absorbers are mounted between the inner plastic cover and outer body sheet metal background. This design approach replaces all trim cover "plastic injection molded dog house" attachments with a net system cost savings.
