CHAPTER FOUR T BONE COLLISION PASSENGER SIDE B PILLAR
In this chapter we will describe in detail the impact of a T-bone collision on the passenger side at the B pillar with 1 meganewton force on the occupants of a unibody 4 door economy car with specificity regarding all 4 passengers, one in the driver’s seat front, passenger seat front, rear drivers’ side rear passenger side. A T-bone (or side-impact) collision at the passenger's side B-pillar with a force of 1 meganewton (MN) on a unibody 4-door economy car is a severe and traumaƟc event. With the direct impact at the B-pillar on the passenger's side, the car's protecƟve structures would be tested extensively, and there is a high potenƟal for serious injuries. Here's a detailed analysis for each of the car's occupants: Driver's Seat (Front): Whiplash: The sudden lateral moƟon can cause whiplash injuries to the driver, as the neck is jerked sideways. It's really important here to understand that there is a thing that happens to our ligaments in these types of hyperflexion and hyperextension injuries, and it's called ligament laxity. And what that means is that the ligament is stretched out of its normal shape, and it never ever ever goes back to its regular shape. When this happens to us in a whiplash type injury, the ligament can no longer hold our head up like it should. As a result of that our muscles take over and try to hold the head up where the ligaments would do it before because that is taxing to our muscles. That's why we get aching necks and pain. That is constant because our muscles are working overtime, trying to take over the job of the now stretched ligaments.
