Abstract:
1. A seat belt buckle, comprising: a frame portion; a release button slidably mounted to the frame portion for movement between a first position and a second position; an inertia locking device rotatably mounted to the frame portion for movement between a blocking position and an unblocking position, the inertia locking device being configured to make contact with a cam surface of the release button when the inertia locking device is in the blocking position and slidable movement of the release button with respect to the frame portion is prevented when the inertia locking device is in the blocking position and the inertia locking device contacts the cam surface of the release button; and a biasing member for providing a biasing force for biasing the inertia locking device into the unblocking position, the inertia locking device being rotated into the blocking position when the biasing force of the biasing member is overcome; wherein a first end of the inertia locking device has a first cavity configured to movably receive a first feature of the frame portion therein and a second end of the inertia locking device has a second cavity configured to movably receive a second feature of the frame portion therein, the first feature and the second feature defining an upper limit and a lower limit of rotation of the inertia locking device with respect to the frame portion by contacting the first cavity and the second cavity.
