When was the seatbelt first installed in cars?

Answer 1

Seat belts were invented by George Cayley in the late 1800s.[citation needed] They were introduced in aircraft for the first time by Adolphe Pegoud, who was among the first men to fly a plane upside-down. However, seat belts did not become common on aircraft until the 1930s. Edward J. Claghorn was granted U.S. Patent 312,085 on February 10, 1885 for a safety belt.[12] American physicians in the 1920s advocated the use of seat belts in cars. Some of them even outfitted their cars with seatbelts. Plastic surgeon Claire L. Straith and physician C. J. Strickland were at the forefront of that demand. Strickland founded the Automobile Safety League of America. The American public showed little interest.[13]
