Possibly something else in the pipeline

From Faurecia's website...another early adoptor

"The actuator that makes this system possible involves a breakthrough technology that Faurecia developed with a specialist-partner, the Fraunhofer Institute. Once the pre-crash sensors give the signal, a wire switch made of Shape Memory Alloy (SMA)releases a spring-loaded bolt that effectively extends the metal tube from the seat to the door on each side of the vehicle. Another actuator closes the gap between the door's exterior shell and interior trim. The result is the creation of a continuous metal tube within 60 milliseconds of the initial signal that redirects the forces of the
collision away from the b-pillar."

certanly look like an intevia initiative...still a few more years in the making tho
