Abstract
A seatbelt tensioning assembly having a seatbelt, a buckle tongue and a tensioning device. The buckle tongue is configured for releasable attachment to a seatbelt buckle within the passenger compartment. The tensioning device is rigidly connected to the buckle tongue with a mid-section of the seatbelt extending through a hollow interior of the tensioning device. The hollow interior of the tensioning device has a first tensioning member disposed therein at least partially defining a seatbelt path having a serpentine shape such that in the absence of tension being applied to the seatbelt the mid-portion of the seatbelt moves through the seatbelt path with the seatbelt path defining a first overall length. With a pre-determined level of tension being applied to the seatbelt, the tensioning device is configured to shorten the seatbelt path to a second overall length smaller than the first overall length.
