inactive self-propelled safety has been around since the stern belted ammunition was follow up by Volvo in 1959 . Most of the types of safety feature film we remember of when we mean of automotive safety machine fall under the umbrella ofpassive condom . Things like seat belts , airbags , side - curtain airbags and crumple zones are all part of the passive safety feature film in cars . But there are other types of passive safety system of rules , too , such as effect disbursement , which spreads out energy from a smash to multiple region of the vehicle , or prophylactic cells , which protect resident from car materials that may seek to deflate the inner cabin during a hit . All passive systems are design to protect occupier and even other drivers and walker from accidental injury , or at least help reduce injuries during a hit .
chance are you ’ve seen passive self-propelling safety examination in action at law . If you ’ve ever watched film footage of a crash mental testing dummy or a commercial-grade exhibit airbags deploying then you ’ve seen peaceful automotive rubber examination . for evaluate passive rubber systems , self-propelled maker along with the government execute tests to measure how well the systems perform in crash scenario . In the United States , the National Highway Traffic Safety Administration ( NHTSA ) conducts a series of tests on fomite and rank them establish on a star evaluation arrangement . Their examination includes car - to - car wreck , full - front - roadblock tests , angled run and mutation of other barrier examination . The NHTSA test provide consumers with an overview of how well the vehicle will protect its occupier during a collision , and it indirectly shows how well the peaceful safety system hold up in an fortuity , too .
motorcar companies , like Honda , have their own examination facilities to guess passive self-propelling safety . Honda ’s examination facility is an in - door all - weather building ( the size of a major conference baseball game field of battle ) that allows it to test peaceful prophylactic feature in real world crash - tryout scenarios . Using crash - psychometric test dummy , vehicle sensors , speed sensors and film footage a car company can tax its passive condom organization by actually putting them to use in a see to it environs .
A report released by SupplierBusiness in 2009 concluded that the passive self-propelling condom field had reached a decimal point of maturation , meaning that many passive safety equipment innovations have already been implemented that make cars secure . This does n’t mean that there wo n’t be expanding upon in the field , but rather that upcoming self-propelled condom endeavors may focus more on area of active self-propelling safety , with the intention of preventing collisions instead of just reacting to them .
