Abstract: A system for providing occupant restraint includes a seatbelt, a tensioning mechanism, and a locking mechanism. The seatbelt may include an upper portion and a lower portion, or just a single span. The tensioning mechanism is configured to remove slack in one or more portions of the seatbelt in response to an event such as an impact event. The locking mechanism is configured to lock an end of the seatbelt after the tensioning mechanism removes the slack, to prevent the seatbelt from extending. A connector may be included that defines an upper portion of the seatbelt and a lower portion of the seatbelt. The tensioning mechanism may include a load limiter to lessen a force transmitted to the seatbelt during tensioning. The load limiter may include an energy absorption element. The tensioning mechanism and the locking mechanism may be coupled to either span.
