Abstract:
A latch assembly includes a chassis and a rotatable claw-type latch bolt moveably mounted on the chassis. The latch bolt has a closed position for retaining a striker and an open position for releasing the striker. The latch bolt is provided with a latch abutment remote from a center of rotation. The latch assembly further includes a pawl rotatable about a pawl axis and having an engaged position for holding the latch bolt in the closed position and a disengaged position that allows the latch bolt to move to the open position. The latch assembly includes an eccentric arrangement defining a first axis and the pawl axis remote from the first axis. The latch assembly also includes a reset lever rotatably fixed to the eccentric arrangement for mutual rotation with the eccentric arrangement about the first axis. The latch assembly includes a biasing lever configured to transmit a biasing force to the reset lever at a position remote from the first axis and to the latch bolt via the latch abutment. The latch assembly includes a biasing device arranged to apply the biasing force to the biasing lever. The latch assembly is configured such that when the pawl retains the latch bolt in the closed position, the biasing lever applies a force to the reset lever to promote disengagement of the pawl, and such that when the pawl is disengaged, the biasing lever promotes the rotation of the latch bolt into the open position.
