Abstract: A belt pretensioner has a base member. The base member has an axial cavity within. An actuating member is hollow and fits within the axial cavity of the base member. The hollow actuating member telescopically slides within the axial cavity and an initiator fits within the hollow portion of the actuating member. In a critical situation such as a crash, the initiator is triggered and the expanding gasses move the actuating member. The actuating member is connected to seat belt webbing and this movement provides the necessary pretensioning of the seatbelt. In some embodiments, a locking means is used to prevent the belt pretensioner from loosening once triggered. One embodiment is provided for use with a child seat. A transversely mounted belt pretensioner embedment is also disclosed.
