Global Automotive Seatbelt Pre-tensioner Market Growth at 7.46%
CAGR during the forecast period
Date: 2016-09-12

As worldwide automobile production exceed 90 million in 2015, and expect 93 million
automobiles will be produced in 2016; some 68.56 million cars were produced worldwide and
about 22.12 million such vehicles were produced globally in 2015, thanks to impetus from
increasing automobile production, the global Automotive Seatbelt Pre-tensioner Market
Growth at 7.46% CAGR to 2020.
Seatbelt pre-tensioner, a passive safety system, is activated when an installed sensor detect
a rapid deceleration during an accident. It is used to manage the occupant’s energy in a crash
by pulling the driver and front-seat passenger firmly into their seats, thereby reducing the
occupant’s load in a violent crash. Automotive seatbelt pre-tensioners tighten the seatbelt
during the first few fractions of a second in a crash.
Types of seat belts
Two-point: A restraint system with two attachment points. A lap belt.
Automatic: Any seatbelt that closes itself automatically. Used mainly in older luxury models.
Sash: Adjustable strap that goes over the shoulder. Used mainly in the 1960s, but of limited
benefit because it is very easy to slip out of in a collision.
Lap and Sash: Combination of the two above (two separate belts). Mainly used in the 1960s
and 1970s, usually in the rear. Generally superseded by three-point design.
Three-point: Similar to the lap and sash, but one single continuous length of webbing. Both
three-point and lap-and-sash belts help spread out the energy of the moving body in a
collision over the chest, pelvis, and shoulders.
Five-point harnesses are safer but more restrictive seat belts. They are typically found in child
safety seats and in racing cars. The lap portion is connected to a belt between the legs and
there are two shoulder belts, making a total of five points of attachment to the seat.
Six-point harnesses became popular after Dale Earnhardt died during a NASCAR race.
Earnhardt was wearing a five-point harness when he crashed and died. Because it was
thought at first that his belt had broken, some teams ordered a six-point harness. The sixth
point has two belts between the legs, which are seen by some to be a weaker point than the
other parts.
