Purpose-built for reclined seating between 25° and 60°, THOR-AV-50M delivers biomechanical insight that empowers safety teams to validate reclined seating with confidence, accelerate development decisions, and stay ahead of evolving global standards.
When seating evolves, safety must follow
Vehicle interiors are changing faster than safety validation tools. Seats recline. Interiors become lounges. Passengers rotate, relax, and disengage from the driving task. What was once a fixed, upright position is now fluid and flexible. But crash testing hasn’t kept pace.
In reclined postures, crash dynamics change completely. The pelvis can slip beneath the lap belt. Crash loads shift into the abdomen and lumbar spine. Airbag timing no longer aligns with forward excursion. Injury mechanisms become asymmetric and three-dimensional. Legacy crash dummies were never designed for this reality. Built for upright seating, they lack the abdominal biofidelity and instrumentation needed to measure these new risks. That leaves engineering teams with blind spots.
And blind spots in autonomous safety are expensive.
Meet the THOR-AV-50M
This next-generation crash test dummy accurately represents human kinematics in upright and reclined positions up to 60 degrees. With 150 high-resolution data channels, it captures detailed biomechanical signals across the head, neck, thorax, abdomen, pelvis, and lower extremities.
THOR-AV-50M delivers measurable clarity where legacy crash test dummies cannot.
Advanced Biofidelic Enhancements for Reclined Seating
Reclined postures increase lap belt angle, shift load paths toward the abdomen, and change how the body moves in a crash. The THOR-AV-50M introduces targeted upgrades to better replicate human-like kinematics and address the unique challenges of reclined seating in autonomous vehicle environments.

1. Biofidelic Neck
The THOR-AV-50M neck is more advanced with improved flexion and extension response. This provides a more biofidelic head and neck movement, supporting more reliable injury prediction.
2. Enhanced Rib Instrumentation.
Provides detailed chest and thoracic load measurements, allowing engineers to fine-tune restraint strategies with greater confidence.
3. Molded abdomen with integrated Abdomen Pressure Twin Sensors (APTS).
The modeled abdomen with integrated APTS enables engineers to get precise measurements of abdominal pressure and injury risk, providing defensible data when evaluating restraint systems.
4. Longer, circular lumbar spine.
Better replicates human torso motion in reclined seating, improving the accuracy of forward excursion and overall kinematic response.
5. Pelvic bone geometry with representative coccyx and ischium structures.
The updated pelvic bone geometry represents the coccyx and ischium structures, which improve belt-to-body interaction and help identify submarining risk earlier in the event.
7. Softer pelvic flesh.
Creates more realistic lap belt loading, leading to more accurate assessment of belt performance and abdominal load paths.
These aren’t small upgrades. They’re purpose-built features designed to deliver realistic biofidelity in reclined crash conditions. The result is more accurate HIC, Nij, and chest deflection data. That means better calibration of multi-stage airbags, far-side airbags, and seat-integrated restraint systems. Instead of estimating airbag timing for reclined occupants, you can engineer it with confidence.
Engineering Confidence Into Every Test
Modern safety validation is both physical and digital. When virtual crash test dummy models are fed incomplete pelvic and abdominal data, simulations can look safer than reality. That leads to late-stage surprises.
The THOR-AV-50M strengthens digital-to-physical alignment with richer abdominal and thoracic data channels. Calibrated FE models are available in LS-DYNA and PAM-CRASH , helping your team reduce prototype loops early in the program.
It also reduces litigation exposure. High-fidelity, defensible biomechanical data strengthens your position when validating novel AV seating architectures .
With the THOR-AV-50M specified for upcoming C-IASI 2026 reclined seat regulations, you are not just compliant. You are prepared. This is risk mitigation at the engineering level.
