Child restraint systems for civil aircraft /

This SAE Aerospace Standard (AS) specifies laboratory test procedures and minimum requirements for the manufacturer of restraint systems for use in civil aircraft. It is intended to establish a minimum level of quality which can be called upon by the designer of those systems. However, compliance with this standard alone may not assure adequate performance of the restraint system under normal and emergency conditions. Such performance requires consideration of factors beyond the scope of this standard, and must be demonstrated by a system evaluation procedure which includes the seat, the occupant, the specific restraint installation and the cabin interior configuration. This standard specifies the requirements for Type 1, Type 2, and Type 3 restraint systems.Buckles that release automatically or through any means other than the direct action of the fingers or thumb on the buckle are beyond the scope of this standard. AS8043B has been reaffirmed to comply with the SAE five-year review policy.

The performance of child restraint devices (CRDs) in commercial transport airplane passenger seats was evaluated by a dynamic impact test program. Background information on the policies and regulations related to child restraints is summarized. Tests were conducted at the FAA Civil Aeromedical Institute. Six types (CRDs) certified for use in airplanes were tested. Booster seats, forward facing carriers, aft facing carriers, a harness device, a belly belt, and passenger seat lap belts were evaluated. Impact tests were conducted with CRDs installed on airplane passenger seats. The test severity was 16 Gpk with an impact velocity of 44 ft/sec. Effects of multiple row seats, aft row occupant impact loads, and seat back breakover were part of the project protocol. Four child size anthropomorphic test dummies were utilized. The 6- month and 36-month size ATDs defined in 49 CFR Part 572, the 6-month size CRABI ATD, and a 24-month size experimental ATD identified as CAMIX were used in these tests. An experimental device to measure abdominal pressure was evaluated in the CRABI and CAMIX ATDS. Analyses of the data acquired from the tests and observations related to the performance of the CRDs in airplane seats are presented. Child restraints, Transport airplanes, Passenger seats.
