4activeOD-3YO
Every year, children lose their lives because they were left unattended in vehicles.
Child Presence Detection systems are a critical line of defense — but only as reliable
as the dummies used to test them.
Meet Heidi. The 4activeOD-3YO is 4activeSystems' Euro NCAP-certified CPD dummy
representing a 3-year-old child — engineered for the highest accuracy in in-cabin
sensor testing.
Key specifications:
- Engineered to Euro NCAP standards
- 17 degrees of freedom
- Highly realistic 3-year-old proportions and surface characteristics
- Natural head, arm & leg movements
- Simulated breathing
