Total Human Model for Safety - THUMS

THUMS AM50 sitting and standing


The Total Human Model for Safety, or THUMS™, is a joint development of Toyota Motor Corporation and Toyota Central R&D Labs. Unlike dummy models, which are simplified representation of humans, THUMS represents actual humans in detail, including the outer shape, but also bones, muscles, ligaments, tendons, and internal organs. Therefore, THUMS can be used in automotive crash simulations to identify safety problems and find their solutions.

THUMS is limited to civilian use and may under no circumstances be used in military applications.

Model Details

The latest Version of the THUMS model is Version 5 (currently only AM50 occupant).

THUMS sizes

Of Version 4, six different sizes of the model are available:

  • Adult female 5th percentile
  • Adult male 50th percentile
  • Adult male 95th percentile
  • 3-year-old child
  • 6-year-old child
  • 10-year-old child

Each of the different sized models is available as sitting model to represent vehicle occupants and as standing model to represent pedestrians.

The models are based on high resolution CT-scans.
