Abstract: A release mechanism for use with fuel filler door latch systems that provides superior control of door movement during the entire service life of the motor vehicle. The biasing mechanism of the present invention includes a kick-out spring that acts directly against the striker bar. As such, the kick-out spring is not exposed to over-stressing and does not cause undue wear of the automobile body. The kick-out spring is a leaf spring having a first end that is secured to the housing, an intermediate section routed between posts extending outwardly from the housing, and a cantilevered second end that is oriented to be engaged and resiliently deflected by the striker bar when the fuel filler door is moved toward its closed position. In the closed position, the striker bar forcibly biases the second end of the kick-out spring to a deflected position.
