Description

Technical Field

[0001] The utility model relates to the technical field of automobile collision test devices, in particular to a device for placing the feet of a whiplash test dummy. Background Art

[0002] In recent years, studies have found that in a rear-end collision, the head of the occupant of the front vehicle will be thrown violently backwards, and the neck will suffer whiplash injuries. The injury lasts a long time and is likely to cause permanent damage. The extent of the injury is mainly related to the performance of the seat and headrest. The low-speed rear-impact neck protection test, also known as the whiplash test, is a test to test the neck injuries of the occupants in a rear-end collision. During the whiplash test, a dummy sits on a seat that imitates the original vehicle structure and is fixed on a moving slide and is restrained with a seat belt to simulate the collision process. The whiplash test is carried out by measuring the injuries to the neck during the collision. The protective effect of the vehicle seat and headrest on the occupant's neck is evaluated.

[0003] However, during the whiplash test, factors such as the foot support height and the foot support angle are not considered. Under different foot support heights and foot support angles, the support strength of the lower body of the whiplash test dummy and the center position of the whiplash test dummy will change. Changes in these factors will affect the injury to the neck of the dummy during the collision after the whiplash test. Failure to consider this factor will lead to a decrease in the accuracy of the experimental results. There is an urgent need for a foot placement device for a whiplash test dummy that can adjust the foot support height and the foot support angle. Utility Model Content
