Yes! The Tummy Shield has undergone several types of testing:
Crash tested to reduce the risk of injury to mom and unborn baby.
Crash tested in Australia to comply with ADR (Australian Design Rule) seat belt guidelines [Australia’s equivalent to U.S. FMVSS standards].
Crash tested at higher than normal crash-test speed.
Strength and integrity tested to withstand seat belt pressure during a crash or sudden braking which could be as high as 2 tons.
Safe Ride 4 Kids did comparison crash testing to compare results of using a Tummy Shield versus just the seat belt.
The manufacturer has done significant “integrity testing” to ensure, to the highest practical degree (ie. 225 male test dummy at speeds exceeding the required test speed for the performance of the seat belt according ADR). They also did instrumented testing on the 5th% female Hybrid III. FMVSS 209 regulates seat belt testing criteria in the U.S. and requires that the breaking point of the webbing for a seat belt be tested to 22,341 Newtons of force. The anchor point on the Tummy Shield is tested to 22,000 Newtons of force or about 5,000 pounds (1,000 newtons = 225 lbs so the 340 newtons difference is a of about 100 lbs. of force — miniscule in crash force terms). We can say with confidence that the anchor point (hook) of the Tummy Shield is tested to the same breaking point as the other components of the seat belt assembly, including the breaking point of the webbing as required by federal safety standards.
