Latch with double pull for closure panel

A latch (10) for operation using a double actuation of a pawl (14), the latch comprising:

• a ratchet (12) movable between a primary closed position, a secondary closed position and an open position, wherein the ratchet is biased towards the open position for facilitating travel of a striker (22) in a fishmouth (23) of the latch to the secondary closed position;
• the pawl movable between a primary locking position, a secondary locking position and an unlocked position, wherein the pawl is biased towards contact with the ratchet, the pawl having a pawl locking surface (31) for engaging a primary locking surface (30) on the ratchet for holding the ratchet in the primary closed position and the pawl has the pawl locking surface for engaging a secondary locking surface (32) on the ratchet for holding the ratchet in the secondary closed position;
• and
• a blocking arrangement for engaging with the pawl and with the ratchet in order to allow or prevent movement of the pawl during a first actuation and a second actuation of the double actuation is, wherein the blocking arrangement coordinates movement of the pawl based on movement of the ratchet interacting with the blocking arrangement.

A method for operation of a latch (10) using a double actuation of a pawl (14), the method comprising:

• moving a pawl of the latch using a first actuation of the double actuation in order to cause a ratchet (12) to move between a primary closed position and a secondary closed position, wherein the ratchet is biased towards the secondary closed position for facilitating travel of a striker (22) in a fishmouth (23) of the latch to the secondary closed position;
• engaging a locking lever (16) of the latch with the pawl using an undercut contour (40) positioned on the locking lever in order to restrict movement of the pawl as a result of the first actuation;
• and
• moving the pawl using a second actuation in order to cause the ratchet to move from the secondary closed position towards an open position, such that the pawl is unhindered by the locking lever and the locking lever is also uninhibited from stopping action of the pawl and thus the locking lever continues to rotate towards an actuated position.
