Seat Headrest Impact Strength Tester
Category：Seating Testers
Introduction
The Impact Strength Tester for Car Seat Launching Headrest is a specialized testing system designed to evaluate the impact resistance, energy absorption capability, and whiplash protection performance of automotive seat headrests under dynamic loading conditions.
By simulating vehicle collision or rapid deceleration scenarios through controlled headform impact, the system accurately measures impact velocity, acceleration response, rebound behavior, and injury-related parameters.
It is widely used by automotive OEMs, seat and headrest manufacturers, certification bodies, and safety research laboratories for regulatory compliance testing, product development, and occupant injury assessment.
Application
(1) Impact strength and energy absorption testing of automotive seat headrests.
(2) Dynamic whiplash injury performance evaluation of headrest systems.
(3) Launch-type headrest deployment and rebound behavior assessment.
(4) Headrest impact safety verification for passenger cars, commercial vehicles, and special-purpose vehicles.
(5) Regulatory compliance testing for vehicle seat and head restraint systems.
(6) Comparative testing of different headrest structures, materials, and energy-absorbing designs.
(7) R&D validation of active and passive head restraint systems.
(8) OEM internal validation and safety rating development testing.
Standards
(1) FMVSS 202a – Head Restraints.
(2) ECE R17 – Strength and safety requirements for vehicle seats and head restraints.
(3) ISO 17373 – Road vehicles – Test method for head restraint impact performance.
(4) IIHS Head Restraint Rating Protocol.
(5) Euro NCAP – Whiplash Assessment Protocol.
(6) OEM technical specifications and internal safety standards.
