<p>A latch assembly comprising :
a chassis;
a rotatable claw-type latch bolt, moveably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, and being provided with a latch abutment remote from its centre of rotation;
a pawl having an engaged position for holding the latch bolt in the closed position and a disengaged position allowing the latch bolt to move to the open position;
an eccentric arrangement defining a first axis and a pawl axis remote from the first axis in which the pawl is rotatable about the pawl axis;
a reset lever rotatably fixed to the eccentric arrangement for mutual rotation with the eccentric arrangement about the first axis;
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 abutment;
a biasing device arranged to apply the biasing force to the biasing lever;
the assembly being 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.</p> |
