Airbags and seat belt pretensioners are the most widely used safety systems for the passengers of vehicles. At the occurrence of a car crash, the crash sensor of these two systems sends a signal to the igniter and the inflator is fired. The signal is sent through Koto hermetic seals to the igniter. Our hermetic seals are designed to realize a strong construction having superior pressure resistance by utilizing our compression sealing technology and optimal material selection.

The hermetic seals for automotive safety systems are required to surely transmit the electrical signals to actuate the hermetically-sealed igniter for a long period of time. We are familiar with the design of the hermetic seals in this field and are able to provide the best solution for customers.
