Upper Seatbelt Retractor (Inflatable Shoulder Belt)
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The shoulder belt includes the seatbelt tongue, which is unique to the inflatable seatbelt system. Attached to the seatbelt tongue is an orifice which is attached to the inflatable shoulder belt and connects to the inflator when the seatbelt buckle and tongue are connected.
The seatbelt shoulder belt retractor only has the Emergency Locking Retractor (ELR) feature.
