A double pawl latch having a ratchet, a primary pawl interacting with the ratchet, a secondary pawl interacting with the primary pawl, and a pawl lever interacting with the secondary pawl. The ratchet has a single notch which interacts with the primary pawl to keep the ratchet in a full striker capture position. If the primary pawl is unintentionally released, the pawl lever includes a backup pawl that interacts with the ratchet single notch, keeping the ratchet in an intermediate striker retaining position where the latch is still closed. The pawl lever initiates opening of the latch by withdrawing the backup pawl from the path of the ratchet and by actuating the secondary pawl. Momentum from the seal force thereafter drives the primary and secondary pawls open, but if the momentum is insufficient the pawl lever can sequentially also open the main pawl after actuating the secondary pawl. |
