Abstract
A seat assembly is provided with a seat frame for a seat back or a seat bottom. At least two side bolster regions are spaced apart laterally on the seat frame. At least two bolster support assemblies are provided, each bolster support assembly comprising an air bladder mounted to the seat frame along each of the side bolster regions. An actuator inflates each air bladder between a deflated position and at least one inflated support position. An accelerometer is mounted to the seat frame. A controller is in electrical communication with the accelerometer and the actuator. The controller is programmed to receive data from the accelerometer indicative of a lateral acceleration. If the lateral acceleration is above a threshold, the controller commands the actuator to inflate one of the air bladders to the inflated support position.
