1. The Dawn of Automotive Safety: Early Seatbelt Adoption

The history of seatbelts is a testament to the gradual recognition of the importance of safety in automobiles. Although the concept of restraining passengers during a collision existed before, it wasn’t until the mid-20th century that seatbelts began to appear in cars.

1.1 The Pre-1950s: A World Without Standard Seatbelts

Before the 1950s, cars were largely devoid of safety features that we take for granted today. Seatbelts were rare, and when present, they were often simple lap belts.

Early Restraints: Rudimentary straps were used in some racing cars and airplanes.
Limited Awareness: Public and manufacturer awareness of passenger safety was minimal.
No Regulations: No laws mandated the use or installation of seatbelts in vehicles.

1.2 1950s: Volvo Takes the Lead in Safety Innovation

The Swedish automaker Volvo emerged as a pioneer in automotive safety during the 1950s. Their commitment to protecting vehicle occupants marked a significant turning point in automotive history.

1955: Volvo Introduces the Three-Point Seatbelt: Volvo engineer Nils Bohlin invented the modern three-point seatbelt.
Early Adoption: Volvo began including seatbelts as standard equipment in its vehicles, specifically in the PV444 model.
Open Patent: Volvo generously made the patent for the three-point seatbelt available to other manufacturers, emphasizing safety over profit.
