Abstract
A low release effort eccentric double pawl vehicle latch includes a ratchet, primary pawl, auxiliary ratchet and secondary pawl in combination with a secure lock lever. The secure lock lever selectively inhibits movement of the secondary pawl to prevent premature or unintended opening of the latch. A drive mechanism sequences movement of the secure lock lever and secondary pawl to open the latch. Upon reset, the drive mechanism drives the auxiliary ratchet back to its closed state and in the process the auxiliary ratchet can engage and return the secondary pawl back to a closed state in the event of an insufficient bias force thereon.
