Abstract: A device, particularly for use by a pregnant woman having an enlarged abdomen. The device attaches to the lap belt portion of a vehicle seat belt assembly for increasing comfort and thus encouraging use of the seat belt assembly, as well as to urge the lap belt portion into proper position across the pelvis. The device includes an attachment portion which can be repeatedly attached to and removed from the lap belt, and a cushioning element attached to the attachment portion at the relatively upper edge of the lap belt for padding the relatively upper edge.
