ABSTRACT:
A seat belt buckle (16) for use with a seat belt pretensioner (30) has an inertia locking mechanism (52). A latch member (64) in the buckle (16) has a locking position for engaging a seat belt locking tongue (14) to block removal of the tongue (14) from the buckle (16). A pushbutton (22) moves the latch member (64) out of the locking position against a bias of a spring (70). The inertia locking mechanism (52) includes a blocking structure (82) which moves into blocking contact with the latch member (64) in response to a predetermined amount of deceleration which occurs when the buckle (16) decelerates and stops moving under the influence of the pretensioner (30).
