ANTI-SUBMARINING BELT FOR A SEAT IN A VEHICLE

A seat for a vehicle includes a frame defining opposing side members and an anti-submarining belt. The anti-submarining belt defines a first end portion, a second end portion, a stowed position, and a deployed position. The first end portion of the anti-submarining belt is fixedly attached to one of the opposing side members of the frame. The anti-submarining belt includes slack when in the stowed position and is pulled taut into the deployed position. The seat includes a seat cushion defining a compressed state and an uncompressed state. The seat cushion rests against anti-submarining belt and is in the uncompressed state when the anti-submarining belt is in the stowed position and is compressed into the compressed state by the anti-submarining belt as the anti-submarining belt is pulled taut into the deployed position. The seat includes a pretensioner connected to the second end portion of the anti-submarining belt.
