How the Defective Seat Belt Law Came About English engineer George Cayley invented seat belts in the mid 19th century. A New Yorker, Edward J. Claghorn, got the first patent. It was for tourists, firemen, painters and others who are being raised or lowered. Hooks and other attachments were needed for securing the person to a fixed object. Then, the shocking death of the iconic actor James Dean in 1955, in a Southern California two-vehicle crash, brought the seat belt to the spotlight. Suspicion that he could have survived that accident, if he was wearing a seat belt, surfaced. By then, people started looking at the optional seat belt differently. But it was slower for the U.S. to catch up and make this a standard. In fact, in 1955, the…show more content…
They are to operate once the vehicle gets started. However,it still involves a lap belt that the occupant needs to manually adjust. Many car owners fail to adjust the lap belt thinking that everything is automatic. Those who do not fasten the lap belt may “submarine” or be thrown forward under the shoulder belt and still end up with serious injuries. Due to the complicated mechanical systems these types of seat belts were prone to, plus confusion on how they work and how to use them, automatic seat belts were scraped…show more content…
This type of restraint system has what’s called a male tongue at one end with a hole or aperture in it. It gets inserted into the female buckle where a spring-loaded latch pin (pawl) passes into the pawl and holds the tongue firmly into the buckle. To extract the pin, one lifts the hinged, spring-loaded buckle. Concerns that these buckles may get accidentally dislodged by an occupant’s movements in the vehicle, arose. The following “side-release” or “top-release” style buckle was designed by General Motors’ Robert C. Fisher because of the accidental dislodging concern. The lift-cover buckle got substituted by a protected button on the side. Thus, the RCF-65 or “Maxi-Buckle” was born. Its spring-loaded button makes the pawl span into aperture when the tongue gets fully inserted into the buckle. Pressing the button would disengage the tongue and buckle. The RCF-65 might seem the buckles we’re seeing today. Its smaller brother, the RCF-67 or Type 1 buckle in General Motors Vehicles, remains the one mostly installed in American vehicles between the two. Its simplicity, durability and light weight enabled easy and cost-efficient manufacture. The RCF-67 had perfect timing because in 1968, the government made seat belts mandatory. This, thus, became the seat belt buckle of
