Seat Belt Test Dummy
The Crash Test Dummy for Seatbelt Testing is a high-precision anthropomorphic test device designed specifically for dynamic evaluation and development of automotive seatbelt systems. It represents a 50th percentile adult male, with physical mass distribution and body dimensions accurately modeled. Constructed from metal, fiberglass, and polyurethane materials, it realistically simulates the skeletal and muscular responses of the human body under dynamic seatbelt loading conditions.
Application
You can use this dummy for:
(1) Dynamic performance verification of automotive seatbelt systems;
(2) Development, optimization, and validation of vehicle seats and occupant restraint systems;
(3) Frontal and oblique collision simulation experiments;
(4) Seatbelt design evaluation and occupant injury assessment;
(5) Regulatory compliance testing according to national and international standards.
Standards
This dummy complies with the following standards:
(1) GB 14166-2013 Motor Vehicle Occupant Restraint System Crash Test Dummy;
(2) ECE R16 Uniform Provisions for Vehicle Seatbelt and Restraint System Certification;
(3) ISO 15830 Road Vehicles – Side Impact Dummy for Restraint System Evaluation.

FAQ
(1) What is this product?
This product is a 50th percentile male crash test dummy designed specifically for dynamic testing of automotive seatbelt systems. It accurately simulates the human skeletal and muscular response under seatbelt loading.
(2) What is this product used for?
You use it to verify seatbelt performance, develop and optimize restraint systems, simulate frontal and oblique collisions, evaluate occupant injury, and conduct regulatory compliance testing such as GB 14166 and ECE R16.
(3) How does this product work?
It works by using a metal and fiberglass skeleton to replicate human bone, with polyurethane covering for muscles and skin. During dynamic seatbelt loading, chest and pelvis displacement sensors record motion, while the dummy experiences forces similar to a real human body. You can analyze these data to evaluate seatbelt performance and occupant injury risk.
(4) Why is this product important?
It provides a repeatable, safe, and precise method to assess seatbelt effectiveness and occupant protection. Without this dummy, evaluating seatbelt design under dynamic conditions would require human testing, which is unsafe and impractical.
(5) What industries is this product suitable for?
It is suitable for automotive manufacturers, safety research laboratories, regulatory agencies, and academic institutions conducting vehicle crash safety and restraint system research.
