Control device for retention arrangement in airbag

摘要

The device comprises sensor devices fastened to a vehicle for detecting a collision acceleration and for providing a corresponding signal. Processor devices are provided for processing the collision acceleration signal through a passenger elastic mass model to provide an adjusted collision acceleration signal. Discriminator devices are provided for controlling a retention arrangement in response to the adjusted collision acceleration signal. The processing devices may comprise devices for the reduction of the value of the collision acceleration signal through a spring force and a viscosity attenuation expression of the elastic mass model.
