摘要： A door latch comprising a forkbolt that has a movement between a latched position and an unlatched position is provided. A detent is included that has movement on a travel path between a first position and a second position, the detent engaging and holding the forkbolt in the latched position when the detent is in the first position. The detent releases the forkbolt for movement to the unlatched position when the detent moves to the second position. A detent spring eccentrically engages the detent relative to the detent travel path and biases the detent toward the first position. A release mechanism is also included for moving the detent against the bias of the detent spring to the second position, thus releasing the forkbolt and producing a non-linear torque on the detent.
