摘要： An occupant classification system for a seat assembly. The seat assembly includes a seat cushion and a seat back. The system comprises a plurality of sensors, an algorithm, a posture classifier and a weight classification system. Each of the plurality of sensors measures a force applied to the seat cushion and/or seat back by an occupant of the seat assembly. The algorithm monitors a compensation factor and adjusts the forces measured by the plurality of sensors to compensate for the compensation factor. The posture classifier identifies a posture of the occupant based on distribution of the adjusted forces for each of the plurality of sensors. The weight classification system identifies a weight class of the occupant based on the posture and magnitude of the adjusted forces for each of the plurality of sensors.

摘要： A ventilated molded seat trim cover for a vehicle seat and a ventilated vehicle seat having a ventilated molded seat trim cover, comprising a stacked assembly of an upper textile layer, a first adhesive layer, an air permeable polyurethane cellular foam interlayer thermo-moldable at temperatures between about 104° C. and about 127° C., a second adhesive layer, a thermoplastic polyurethane (TPU) film, a third adhesive layer, and a scrim backing layer. The stacked assembly is compression molded in a 3-dimensional mold while at least a portion of the foam interlayer is heated to a temperature between about 104° C. and about 127° C. to form the ventilated molded seat trim cover. The TPU film prevents airflow passing through a bottom surface of the seat trim cover. Airflow in the foam interlayer can pass through the upper textile layer.

摘要： Methods, devices and systems are provided for detecting drowsiness or the alertness level of a driver of vehicle. A driver's heart rate variability level is determined based on signals received from one or more sensors placed in the vehicle, such as biometric sensors located in a seat assembly. In response to a low heartbeat variability indicating a drowsy or non-alert driver, one or more output signals may be generated to warn or notify the driver.
