A vehicle seat occupant classification system for use in a vehicle seat includes a weight-responsive sensor, at least one bracket member serving as a holder for the weight-responsive sensor, and an evaluation unit configured to evaluate a status of the at least one weight-responsive sensor. The bracket member is fixedly attached to the seat base. If a mechanical load at least corresponding to a first pre-determined threshold value is applied by a seat occupant, a portion of the vehicle seat comes into mechanical interaction with the at least one weight-responsive sensor, and is configured to change a status of the at least one weight-responsive sensor if a mechanical load at least corresponding to a second pre-determined threshold value is applied. Relative movement between the seat base and the at least one weight-responsive sensor is at least excluded for applied mechanical loads that are smaller than the first pre-determined threshold value.
