Abstract: The present invention relates to a supplemental seatbelt buckle cover system. The seatbelt buckle cover of the present invention is adapted to be removably positioned over a seatbelt buckle to protect a user from such a seatbelt buckle which may have inadvertently heated while in an automobile. In its broadest context, the cover includes a upper open end, a lower open end, a first open side and a second open side, as well as a slot positioned along the rearward wall of the cover. The slot allows the cover to be positioned over the shoulderbelt of a seatbelt or, in the alternative, the lapbelt of a seatbelt, rotated 90 degrees and slid onto the seatbelt buckle. Two springs are positioned within the opened first and second sides of the cover to allow the cover to be resiliently positioned and securely maintained upon the seatbelt buckle.
