Abstract
An anti-submarining seat structure includes a seat frame, upholstery, an anti-submarining device, a sensor and a controller. The upholstery overlays the seat frame at least partially forming a seat cushion portion with a cavity between the seat frame and a portion of the upholstery adjacent to a front area of the seat frame. The anti-submarining device is installed within the cavity and is configured to transition from an unactuated orientation to an actuated orientation. In the actuated orientation, the anti-submarining device forms a restraining structure proximate the front area of the seat cushion portion. The sensor is configured to detect rapid changes in acceleration and velocity of the vehicle body structure. The controller is connected to the anti-submarining device and the sensor and is configured to actuate the anti-submarining device in response to signals from the sensor indicating a rapid change in acceleration and velocity of the vehicle body structure.
