Seat Belt Assembly
The fixed anchor point and seat belt tensioner are mounted on the seat frame. The upper deflection point of the belt is attached to the head rest which causes the belt to be optimally positioned when the head rest is moved.
The inertia reel locking mechanism is attached to the backrest frame of the seat. It consists of two independent triggering devices which act on the inertia reel.
- The first triggering device locks the belt during fast cornering, heavy braking, roll over or during impact.
- The second triggering device serves as an auxiliary safety lock and is controlled by the "Mass Moment of Inertia". The position of the mass moment of inertia is a decisive factor for the belt to lock.
The inertia reel locking mechanism is connected through a lever and a cable drive to a gear assembly on the seat back hinge. As the angle of the backrest is adjusted, the gear assembly and cable drive will change the angle of the inertia lock. This ensures that the lock is in the proper position for locking at any seat back angle.
