US Classification:
60528, 248636, 267154
Abstract:
A tunable impedance load bearing structure includes a support comprising an active material configured for supporting a load, wherein the active material undergoes a change in a property upon exposure to an activating condition, wherein the change in the property is effective to change an impedance characteristic of the support.

International Classification:
B60R 22/00 B60N 2/02
US Classification:
2808011, 296 681
Abstract:
A method of autonomously preventing or reducing the affects of roof impact in automotive applications, including the steps of determining a vehicle condition indicative of an imminent roof impact, and modifying a vehicular seat or roof structure, or deploying a netting as a result thereof, wherein active material actuation is preferably utilized to effect the same.

International Classification:
B60R 21/34
Abstract:
An energy absorber according to various embodiments can include a structure having a predetermined cross-sectional profile. A hollow profile is formed within the structure. The pre-determined cross-sectional profile of the structure is configured based on a deceleration-time profile that includes a first period and a second period. The first period is defined by a substantially sharp and linear increase in magnitude of the deceleration of an impact until a maximum deceleration value is achieved. The second period is defined by a rapid decrease in the magnitude of the deceleration.
