What is side impact test?

What is side impact test?

Side impact crash tests consist of a stationary test vehicle struck on the driver side by a crash cart fitted with an IIHS deformable barrier element. The 1,500 kg moving deformable barrier (MDB) has an impact velocity of 50 km/h (31.1 mi/h) and strikes the vehicle on the driver side at a 90 degree angle.

What are 2 criteria for side impact crashes used in the 5 star rating system?

In side-impact crashes, there are two criteria: Thoracic Trauma Index (TTI) Lateral Pelvic Acceleration (LPA)

What is NHTSA safety rating?

Safety Ratings. NHTSA’s 5-Star Safety Ratings help consumers compare vehicle safety when searching for a car. More stars mean safer cars. Combines Driver and Passenger star ratings into a single frontal rating. The frontal barrier test simulates a head-on collision between two similar vehicles, each moving at 35 mph.

Are all car seats side impact tested?

Car seats are not currently tested for performance in a side-impact crash test. In 2002, however, NHTSA analyzed how two car seats performed, one convertible seat and one rear-facing infant seat, in side-impact tests of eight vehicles, as an experiment to see if side-impact data could be successfully obtained.

Why is there no NHTSA rating?

Why doesn’t NHTSA do rear impact crash ratings? NHTSA’s 5-Star Ratings Program has a limited budget and must concentrate its ratings on front and side-impact crashes that are responsible for the highest percentage of deaths and serious injuries.

Are IIHS ratings reliable?

IIHS Picks Its Safest Cars Like NHTSA, it generally chooses vehicles that sell in high numbers and are new or significantly updated. Ratings are Good, Acceptable, Marginal, or Poor.

Why are crash test done at 35 mph?

To keep people safe there will always be a crash test. There are far more accidents that occur at lower speeds than at higher speeds.

How are car seats crash tested?

Crash testing – also referred to as dynamic testing – involves properly securing a crash test dummy into a car seat that is properly installed on the crash test bench. The test bench is then accelerated and decelerated at a specific speed to simulate a frontal collision at 30 mph (48 km/hr).

Do Graco car seats need to be replaced after an accident?

A: Yes. Graco recommends replacing the car seat in the event of any type of accident.

Who is at fault in a side impact collision?

If the turning vehicle was supposed to yield the right of way but did not, and hit a car, the turning driver is responsible. On the other hand, if a driver was making a legal left turn with a green turn arrow and someone ran a red light and crashed into the turning driver, the non-turning driver is liable.

At what speed will side airbags deploy?

Because of the small space between an occupant and the side of the vehicle, side airbags must deploy very quickly, typically within the first 10-20 milliseconds of a side crash.

What is side pole crash test?

The test vehicle, angled at 75 degrees, is then pulled sideways at 20 mph (32km/h) into a 25-cm diameter pole at the driver’s seating location. This test mimics a side impact crash involving a narrow, fixed object like a utility pole or tree.
