Abstract
A seat belt pretensioner including a casing defining a pivot axis and having a locking member, a driving mechanism supported by the casing, a flexible connecting member, and a cam. The driving mechanism includes a movable member that moves relative to the casing during pretensioning. The flexible connecting member has a first end coupled to the movable member and a second end that is attachable to one of the anchor, the buckle and the webbing. The cam includes a locking surface having a cross-sectional shape that is an Archimedean spiral. The cam is rotatable about the pivot axis between a non-locking position, in which the connecting member is able to freely move between the cam and the locking member, and a locking position, in which the locking surface clamps the connecting member to the locking member to prevent any further movement of the connecting member relative to the locking member.
