OC3 Mat

US legislation stipulates that the use of a child restraint system tested by NHTSA and holding a small child on the front passenger seat must be detected automatically and the front passenger airbag disabled.

The OC3 mat can detect an occupied child seat tested in accordance with the regulation (NHTSA FMVSS 208) on the basis of the pressure per unit area and disable the passenger airbag (front and side airbag). The passenger airbag OFF light comes on when a child restraint system tested in accordance with NHTSA and holding a small child was detected on the front passenger's seat.
