Impact barrier for a storage unit

An impact barrier for a support structure, the impact barrier comprising:

• an outer wall forming an interior space;
• a first deflection element extending into the interior space;
• a second deflection element extending into the interior space;
• a third deflection element positioned between the first deflection element and the second deflection element, the third deflection element extending into the interior space, the third deflection element having a base segment;
• a first living hinge and a second living hinge, the first living hinge disposed between the first deflection element and the third deflection element and the second living hinge disposed between the second deflection element and the third deflection element,
• wherein the first deflection element extends from a first position on the outer wall and joins with the outer wall at a second position between the first position and the third deflection element, the second deflection element extends from a third position on the outer wall and joins with the outer wall at a fourth position between the third position and the third deflection element,
• wherein at least a portion of the base segment of the third deflection element is parallel to a plane extending across the second position and the fourth position;
• wherein the first deflection element has two segments with ends intersecting at a first angle in the interior space of the impact barrier and the second deflection element has two segments with ends intersecting at a second angle in the interior space of the impact barrier;
• and
• wherein at least one of the first angle and the second angle is an obtuse angle.
