ABSTRACT:
The present invention is directed to an end release belt buckle that is operable for releasable latching a tongue plate of a vehicular safety belt restraint system. The end release belt buckle of the present invention includes a base having a latch portion adapted to lockingly engage the tongue plate. The end release belt buckle further includes a release mechanism for permitting the seat occupant to intentionally release the tongue plate from locked engagement with the latch portion of the base in response to movement of a push-button actuator from a "latched" position to a "released" position. The push-button actuator is normally biased to the "latched" position by a spring-biasing mechanism. In addition, the end release belt buckle further includes a locking mechanism for inhibiting unintentional movement of the push-button actuator from the "latched" position to the "released" position when the vehicle is subjected to a deceleration force exceeding a predetermined threshold value.
