Front Angled Impacts

The deployment of airbags and seat belt pre-tensioners that occur when a vehicle is involved in a front angled collision is dependent on the speed and angle of the impact. Four possible conditions could apply:

• Impact is below the threshold for the control unit's front impact sensor and the side impact crash sensors - no response, none of the airbags or seat belt pre-tensioners are activated.
• The speed and angle of the impact is in excess of the front impact trigger threshold, but below the threshold of the side impact crash sensors - the driver's airbag, passenger's front airbag and front seat belt pre-tensioners are activated.
• The speed and angle of the impact is in excess of the side impact trigger threshold, but below the control unit's front impact trigger threshold - the driver's side (thorax) and AHPS2 airbag circuits are activated in a driver's side impact and the passenger side (thorax) and AHPS2 airbag circuits are activated in a passenger's side impact. In addition, both front seat belt pre-tensioners are activated.
• Both the front and side impact trigger thresholds are exceeded, the driver's front airbag, passenger's front airbag and both front seat belt pre-tensioners are activated. In addition, the side (thorax) airbags and the AHPS2 airbags on the side of the vehicle suffering the impact are activated.
