Seat belt pretensioner

Seat belt pretensioner
As a primary safety feature of a vehicle, seat belts must absolutely meet the highest safety standards.
The reversible seatbelt pretensioner, a forward-thinking seatbelt feature, replaces outdated solutions of the past, providing passengers with next-generation seatbelt safety.
As before, there are other factors driving this ASIL B application. The solution needs to be reliable, price-conscious, and offer a high level of integration.
Infineon's portfolio includes highly integrated solutions (best-in-the-market level of integration) for reversible seatbelt pretensioners.
Furthermore, it contributes to saving valuable space and reducing costs.

The advantages of the system are as follows:
Seat belts remain a primary safety feature for protecting vehicle passengers from serious harm.
By adjusting the belt tension before a collision, the severity of injuries is reduced, while also improving passenger comfort during normal use.
Safety experts predict that reversible seatbelt pretensioners will become the mainstream in the future.
