In order to detect whether the buckle latches are inserted in the belt buckles or not, new belt buckles with separate switches and resistors were
necessary. This results in the triggering logic listed below.
Release Logic, Driver's Airbag and Belt Tensioner
Explanation:
In a minor accident, in which the safety belt provides adequate protection, only the belt tensioner is activated when the first release threshold is passed,
provided the belt buckle is fastened.
In a more serious accident, whereby the second threshold is passed, the airbag is also activated.
Release Logic, Driver's and Front Pass. Airbag and Belt Tensioner
Explanation:
In a minor accident, in which the safety belt provides adequate protection, only the belt tensioner is acuvated when the first release threshold is passed,
provided the belt buckle is fastened.
If the belt buckles are not fastened or the second release threshold is passed, the driver's and passenger's airbags will be activated instead of, or in
addition to, the belt tensioners.
