The position of the automobile head restraint is very important for the neck injury in the rear end collision. This study was analyzed about influence of the head restraint height and distance on neck injury during rear end collision. The effects of the position have been evaluated experimentally. The neck injuries are calculated by the relative acceleration between the upper and lower acceleration. A good head restraint position has been founded from analysis results based on the height covered head and the distance closed the back of the head. Also, a active head restraint is very useful for the neck injury.

According to a statistics, the claims paid by insurance fraud over 423 billion and 7 hundred million won in 2011, increased by 13.1% compared to 374 billion and 7 hundred million won in 2010. This result in increasing of premium by 200 thousand won per family and 70 thousand won per person, respectively. Nowadays, insurance fraud especially related to car insurance is threatening to people"s life. In this study, we reconstructed a vehicle crash accident suspected to an insurance fraud to evaluate crash speed and the relationship of vehicle crash and risk of passenger injury. To do this, the scene was reconstructed based on accident investigation report and three vehicle crash tests were done at 27kph, 37kph and 70kph. Based on the damage of vehicle, impact speed is estimated around 20 to 30kph and it"s really hard for passenger to be injured in this speed range. The test result was reported to police and court to be used as a reference of this case.
