In a small overlap collision, the vehicle moves simultaneously in the longitudinal and transverse directions and sweeps the barrier or has rotational motion depending on the degree of deformation and support of the vehicle body. In particular, the rotational motion of the vehicle increases the lateral behavior of the occupant and can even cause occupant’s head to contact A pillar. Therefore, it is necessary to study restraint conditions to minimize the lateral behavior of occupant. In this study, we will define restraint conditions that affect behavior of occupant and introduce the results of sled test in the small overlap collision mode.

Various kinds of vehicle crash modes such as frontal, angle, pole crash exist in the field, and many safety engineers have analyzed vehicle pulses of those different crash modes to obtain optimal airbag inflation time and to improve occupant injury performance. Among above crash modes, pole crash frequently occurred in the field; Center pole crash test is conducted not only to simulate the crash between the vehicle and the utility pole or a roadside tree in the car development stage but also to investigate RTTF (Recommended Time To Fire) in the aspect of due care situation. In this study, center pole crash tests according to five velocity conditions were carried out, and five full frontal crash tests were conducted. The velocity conditions of center pole crash tests are 13mph, 17mph, 19mph, 23mph, and 27mph. Those of full frontal crash tests are 12mph, 16mph, 18mph, 22mph, 25mph, and 30mph. We will analyze vehicle crash acceleration pulse, velocity pulse, injury performance, and RTTF between the center pole crash and the full frontal crash.

Knee airbag is a kind of advanced kneebolster system which plays an important role in protecting occupants’ lower extremities from vehicle crash and improving occupants’ behavior to minimize their injury. NHTSA recently announced that NCAP rating method will be severely revised and many OEMs will be a difficult situation for getting new NCAP five stars. Nowadays knee airbag is being introduced to car makers and they are also considering applying knee airbag to their vehicle and requesting suppliers to develop optimum knee airbag for their vehicle. This paper will introduce the advantages of blow molded plastic active knee airbag and describe the superiorities of its performance through sled test results.

Knee bolster system in passenger vehicle driver side cockpit consists of reinforcement panel and brackets which are connected to cowl cross member and plays an important role in improving crash dummy behavior and femur injury. For example, it distributes dummy kinetic energy to both femurs and prevent dummy from sliding below lower crash pad. To design optimized knee bolster system, we have to consider coverage zone of reinforcement panel, reinforcement panel angle, bracket shape, and so on. In this study, knee bolster systems of four vehicle platforms were investigated as a case study. The inner package of lower panel was examined and the results of sled and barrier test were analyzed to present design guideline of knee bolster system.

The objective of safety system is to reduce damage to life and property in crash accidents. Automotive safety systems are built to reduce not only the number and severities of injuries but also the likelihood of crashes. Recently, the consciousness of consumers for safety system has been changed. They are trying to buy safer car referring to crash test results such as NCAP and IIHS and are interested in active safety system as well as passive safety system. Therefore car maker and supplier have to make an effort to satisfy consumer's requests and correspond to enforced regulation and also try to develop new safety system technology. This paper will describe the market trend of active and passive safety system in Europe and North America and introduce technology of new safety system.

Nowadays the most raising issues in the airbag industry are cost and assemblability. Many car makers are considering applying low cost passenger airbag to their vehicle. In this paper, the inverse ‘Ω’ shape two panel passenger airbag was suggested to have cost competitiveness and good safety performance. The Sewing pattern that makes inverse ‘Ω’ shape, increases cushion depth and protects passenger more safely. This paper will introduce the advantages of the developed two panel passenger airbag and describe the superiorities of its performance through sled test results.

Many safety researchers have tried to control airbag deployment shape by changing bag folding pattern and tether location or adjusting tether length. Changing bag folding pattern of above methods has advantages in the aspect that there is no additional cost and it is not affected by airbag shape changes due to design change. Airbag folding patterns have an effect on not only airbag inflation characteristics but also OOP injury performance. In particular, airbag inflation characteristics such as bag internal pressure and airbag deployment shape play an important role in controlling dummy kinematics during vehicle crash and reducing OOP occupant injury.<br/> In this study, passenger airbag deployment performances according to four kinds of folding patters are investigated. Bag internal pressure, airbag burst distance and angle, airbag deployment trajectory, and bag eccentricity were measured to research passenger airbag deployment performance.

The vehicle’s lateral motion is one of the important factor to generate the dummy’s behavior during the IIHS small overlap crash event. In this respect, to accomplish sled tests successfully, it is necessary to simulate the vehicle’s longitudinal and transverse motion simultaneously. This paper describes a new test method on a small overlap sled test by simulating the vehicle’s dynamic lateral motion. The lateral motion was generated by using guide path which includes vehicle’s analysed lateral movement information, and linear motion guides and rails that could be allowed to move to lateral direction of vehicle’s body for sled test.
