Walter Linderer was a German engineer.


Reported in 1951, German engineer Walter Linderer designed an airbag.[1] Linderer filed German patent #896,312 on October 6, 1951 which was issued on November 12, 1953, approximately three months after American John Hetrick was issued U.S. patent #2,649,311 earlier on August 18, 1953.[2] Linderer's airbag was based on a compressed air system, either released by bumper contact or by the driver. Later research during the 1960s proved that compressed air could not blow Linderer's airbag up fast enough for maximum safety, thus making it an impractical system.[3][4]
