“…Although the human injury standard table suggests injury standards for six parts of the human body, the cervical spine is critical for human activity; therefore, it is necessary to determine the degree of human injury from the perspective of neck injury. Kaneko et al (2004) calculated the NIC in a collision using Equations (1) and ( 2) [14][15][16][17].…”

Because of the function of facilities that transport individuals and luggage to elevated locations, poor maintenance and human errors by users and workers can result in many elevator accidents annually. In particular, given the characteristics of an elevator used by an unspecified number of people, in the event of a fall accident due to wire rope cutting, an occupant’s body may be fatally injured, thereby causing substantial human damage. To minimize human injury, it is important to reduce the relative impact speed between the car and the pit by utilizing the buffer effect according to the role of the safety device and the posture of occupants. The AIS (Abbreviated Injury Scale) is an anatomical-based coding system established by the Association for the Advancement of Automotive Medicine that classifies and describes the severity of injuries. In this study, through human injury analysis, safety device operation such as speed governor and buffer when cutting elevator wire rope, occupant’s behavior, and air mat usage were used to derive force and torque values for the injured part, and then determine the amount of impact and degree of injury to the human body using the multibody model provided by the MADYMO program and AIS by analyzing the buffering effect of the impact.

Whiplash injury due to low severity vehicles crash is a global problem. The injury has long-term clinical and biomechanical implications. Since the mid-1960s, injury statistics have continuously revealed that females face a higher risk of suffering the injury category compare to males. Besides, in a frontal crash, the injury measures from the adult rear dummies were mainly higher than the same size dummies located in driver and front occupant seat. However, most regulations and user crash tests have focused on vehicle drivers and front-seat passenger due to high occupancy and mortality rates in the front seat. In this paper, mechanisms of whiplash injury were reviewed to contribute a further inclusive understanding of human impact reaction, variability quantification, validation, and prevention. The objective of this study is to develop a new design of head restraint (HR) for car rear occupants. In order to raise consideration whiplash injury and prevention mechanisms, impacts are simulated with computer modelling (Ls-Dyna simulation) and validated using Matlab. Therefore, a review of these injury mechanisms indicates the development of new anti-whiplash technology in the automotive safety area is necessary.
