The FAA's summary their words, unchanged

These special conditions are issued for the installation of an AMSAFE, Inc. Inflatable Three-Point Self-Adjusting Restraint Safety Belt with an Integrated Inflatable Airbag Device on the Zenair model CH2000. This airplane, as modified by AMSAFE, Inc. will have novel and unusual design features associated with the lap belt portion of the safety belt, which contains an integrated airbag device. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
