SN3013 Seat Belt Dummy

I. Overview:

1.1 Equipment Purpose and Function Overview

The SN3013 dummy is a loading device used in automotive crash simulation experiments for dynamic testing of seat belts and research and development trials. Its physical mass and dimensions are designed based on the 50th percentile human body distribution.
In crash tests, this dummy serves as an applicable counterweight. The design omits the forearms and includes only one lower leg.

It is primarily used in crash tests to evaluate automotive seat belts, simulating human body weight and motion posture, while also enabling the testing of the dynamic strength of seat belt restraint systems.
