Out Of Position (crash Testing)
Out of position (OOP), in crash testing and car accident medical literature, indicates a passenger position which is not the normal upright and forward-facing position. For example, a common case observed in crashes is the position of an occupant when reaching for the car radio, or panic braking in unbelted passengers. The concept is of interest because small changes in a passenger's position can have profound effects on the actual kinematic response, especially in rear impacts, as shown both in practical testing and theoretical models. Risk of injury Out of position occupants are at increased risk of injury. Even low speed impacts can cause disc herniation and Lumbar vertebrae, lumbar fracture on OOP passengers. Airbags can prove fatal on OOP passengers: modulating the airbag folding pattern has been proposed as a method to reduce injuries. Crash testing has shown increased forces acting on the neck and torso when crash test dummy, dummies were leaning forward and not upright; a ...

Crash Test
A crash test is a form of destructive testing usually performed in order to ensure safe design standards in crashworthiness and crash compatibility for various modes of transportation (see automobile safety) or related systems and components. Types * Frontal-impact tests: which is what most people initially think of when asked about a crash test. Vehicles usually impact a solid concrete wall at a specified speed, but these can also be vehicle impacting vehicle tests. SUVs have been singled out in these tests for a while, due to the high ride-height that they often have. * Moderate Overlap tests: in which only part of the front of the car impacts with a barrier (vehicle). These are important, as impact forces (approximately) remain the same as with a frontal impact test, but a smaller fraction of the car is required to absorb all of the force. These tests are often realized by cars turning into oncoming traffic. This type of testing is done by the U.S.A. Insurance ...
