Component Parts and Harness Connector LocationNHS0007X
System DescriptionNHS0007Y

Pre-crash seat belt system is adapted to front seat belts RH/LH.

When the pre-crash seat belt control unit judges the emergency braking operation, it gives the sense of
security by the motor built into the pre-crash seat belt retracting the shoulder belt and suppressing the
crew's posture change. Also, it eases the damage of the collision.
