IMMI 4Front frontal airbag system

• Make: IMMI
• Model code: 4Front

4Front® by IMMI® is designed to protect firefighters and truckers in the most common type of accident-a head-on crash. When the 4Front sensor detects a frontal crash, it sends a signal to initiate three events that provide protection for the driver and/or first officer: The system tightens seat belts around the driver and/or first officer to position them securely in their seats. It pulls down the suspension seats to their lowest position to increase survivable space. The system inflates a steering wheel airbag to protect the head and neck of the driver, while inflating a knee bolster airbag to protect the first officer’s legs.
