Abstract
A latch assembly for a closure panel of a vehicle includes a power release actuator, a pawl, a ratchet, and a multi-stage geartrain. The multi-stage geartrain includes a first compound gear and a second sector gear in meshed engagement with the compound gear. The sector gear includes an arm extending radially therefrom. In a rest position, a gap is defined between the arm and a cam surface of a pawl. Actuation of the power release actuator actuates the multi-stage geartrain and pivots the arm through the gap and into contact with the pawl. During pivoting through the gap, inertia is increased and the arm contacts the pawl with an impulse force. Continued rotation of the arm causes further rotation of the pawl and release of the ratchet. The arm is disposed within an axial height defined by the multi-stage geartrain, and torque applied to the arm increases during rotation.
