Abstract: The present invention relates to a weight-drop machine for calibrating and verifying the calibration of an occupant detection system in a vehicle. The machine comprises a lift frame that is adapted to support and lift a seat pallet toward a keeper plate to cause the pallet to engage the keeper plate so that the pallet is prevented from movement. Another weight-drop machine a weight supported for movement relative to a frame, which, in turn, is supported for movement in a direction having both a horizontal component and a vertical component of movement in a single motion. Yet another weight-drop machine comprises one or more sensors that are adapted to sense the position of a vehicle seat. Still another weight-drop machine comprises a sensor for measuring displacement of the drop weight. A towel bar lift may be provided for lifting a towel bar for operating a manual seat lock mechanism.
