Head Restraint Performances (HRP) Test Rig

The Head Restraint Performance Test Rig is an advanced, fully electrical testing system engineered to evaluate the structural strength, stiffness, and safety performance of automotive seats, seatbacks, anchorages, and head restraints.

Designed to meet global automotive safety standards, this system plays a critical role in validating occupant protection during rear-impact scenarios. Its robust architecture enables simultaneous and independent testing of up to three seats, making it a highly efficient and cost-effective solution for OEMs, test labs, and R&D centers.

Why Head Restraint Testing Matters

Head restraint systems are essential for minimizing whiplash injuries during collisions. The HRP Test Rig ensures that seating systems comply with international regulations while maintaining structural integrity under dynamic loading conditions.

The system has been designed according to the following regulations:

  • FMVSS 202A, FMVSS 202
  • ECE R17, R25 
  • GTR 7
  • EEC Dir 78/932
  • GB 11550 – 1995, GB 15083 – 2006
  • IS 15546 – 2005
  • AIS 016, AIS 023
Key Capabilities
  • Comprehensive Seat Evaluation
    Accurately measures the performance of seat structures, backrests, anchorages, and headrests under controlled loading conditions.
  • Multi-Seat Testing Efficiency
    Capable of testing up to three seats simultaneously and independently, increasing throughput and reducing testing time.
  • Global Standards Compliance
    Fully designed to meet major international regulations including:
    • FMVSS 202 / 202a
    • ECE R17, R25
    • GTR 7
    • AIS, IS, GB and EEC directives
Advanced System Features
