Belt lock system in general

The mechanical automatic belt retractors for the seats are equipped with a belt lock system. The belt extension is blocked depending on the vehicle acceleration and vehicle inclination.

Belt lock system function sequence

The vehicle-sensitive belt lock sensor (A60) constantly monitors the vehicle's acceleration and incline angle.

If one of these variables exceeds the permissible limit value (vehicle acceleration > 0.45 g or vehicle inclination
> 27°), the vehicle-sensitive belt lock sensor sends a signal to deploy the belt lock to the left front seat adjustment control unit with memory (N32/1) and to the right front seat adjustment control unit with memory (N32/2). Each front seat adjustment control unit then actuates the left front belt lock solenoid (Y96) and the right front belt lock solenoid (Y96/1) to lock each belt extension.

The front seat adjustment control units receive a constant signal from the vehicle-sensitive belt lock sensor and as a result they can detect any faults in the actuation circuits for the solenoids. The error messages are shown in the instrument cluster (A1).
