Envelope of Protection for Crashes against Obstacles
In the case in which the user of a motorcycle strikes a vehicle or an obstacle, the System
is expected to have an intervention time within 200ms from the moment of first contact
between the motorcycle and the vehicle (or obstacle), within the arrival speed and impact
angle conditions reported in Table 2 and Figure 3 below. Refer to Section 20 "Certification
Information" for the complete list of tests.

Impact Angle
Table 2: Crash Conditions – Crashes Against Obstacles or Vehicle
IMPORTANT!
Figure 3 outlines the Envelope of Protection where the System is expected
to inflate before the User's body contacts an obstacle. At speeds above
50km/h the System is expected to deploy regardless of the impact angle,
but outside the Envelope of Protection the System may not be fully inflated
before there is contact between the obstacle and the User.
IMPORTANT!
If the speed of the motorcycle is less than 25km/h (15 mph), the System
may not deploy at the time of the collision/crash but may deploy if the user
suddenly falls from the motorcycle after the impact.
