Seat Testing Systems

Advanced test & validation solutions for automotive seating — from seat frames to intelligent Seat ECUs

At Trinitas, we offer advanced test and validation solutions for automotive seating systems, ensuring safety, comfort, and durability across all vehicle platforms.

 

Our services include mechanical, ergonomic, and functional testing, covering seat frame strength, recline and adjustability mechanisms, cushion durability, and occupant safety features such as airbags and sensors.

​

By integrating automated test benches, environmental stress simulation, and measurement systems, we help OEMs and suppliers verify compliance with industry standards while delivering high-quality, reliable seating systems that enhance passenger comfort and safety.

Mechanical Subsystems

  • Electric Actuation: Precision electric actuators provide controlled force/torque application and high-repeatability positioning.

​

  • Height-Adjustable Leadscrew Fixture: A rigid, leadscrew-driven fixture allows flexible seat placement and rapid alignment across seat models and platforms.

​

  • Swap-Friendly Interfaces: Modular testing setup to incorporate different seat frames; quick clamps for throughput; reference datums for repeatability.

​

  • Endurance & Fatigue: Variable load amplitudes and frequency-controlled cycling for endurance; ramp-to-failure modes for limit characterization.

​

  • Environmental Readiness: Optional interfaces for chamber integration (thermal/humidity) and vibration inputs for combined-stress testing.

Test Automation & Management

  • Platforms: LabVIEW, NI TestStand (sequence-based automation), or alternative frameworks per customer standard.

​

  • Capabilities: Test plan management, profile editors (force/frequency/angle), safety checks, real-time visualization, limit checks, and automated pass/fail.

​

  • Integrations: Barcode/serial capture, Power supply control, chamber control, and high speed camera-based observation (optional).

Safety & Interlocks

  • Emergency Stops: Hardware e-stop circuits with immediate drive disable and mechanical brake engage.

​

  • Physical Guards: Fixed guards and interlocked doors (category-rated), optional light curtains or two‑hand control.

​

  • Travel Safety: Software travel limits, soft torque/force limits, anti-backdrive measures, and emergency retract.

​

  • Power Safety: Safe power-down, overcurrent protection, and LOTO-ready design.

​

  • Workflow Safeguards: Pre-test checklists, seat clamp detection, operator prompts, and permission roles.

​

  • Documentation: Risk assessment, wiring diagrams, and safety validation test cases.

Mesaurement & Loading circuit

  • Force / Moment Sensing: High-accuracy load cells  with inline signal conditioning.

​

  • Displacement & Angle: Linear encoders/LVDTs and rotary encoders for deflection, angle, and travel.

​

  • Power & Current: Precision current/voltage sensing to characterize ECU-driven loads (motors, heaters, valves, fans).

​

  • ECU Load Simulation: Custom electronic load boards emulate DC motors, H-bridge loads, resistive heaters, PWM fans, and sensor inputs (e.g., potentiometers/Hall, NTCs, occupancy mats). Safe squib dummy loads and monitoring for airbag circuit simulation (no live deployment).

​

  • Signal Integrity: Shielded cabling, proper grounding, and filter design for clean measurements.

Data Logging & Reporting

  • Centralized SQL Database Storage : Automatically logs all test data and events in secure SQL database for long-term traceability.

​

  • Individual Seat test Traceability : Tracks each test by serial number or barcode for compliance and quality control.

​

  • Automated Report Generation : ​Generates detailed test reports in CSV and PDF formats for easy sharing and documentation.

​

  • Analytics & ML: Trend analysis, anomaly detection, and ML-based failure prediction models to detect degradation patterns early and reduce rework.

​

  • MES & QA System Integration (Optional) : Connects with customer systems for centralized data management and real-time monitoring.
