A lock unit for a vehicle includes a rotatable catch biased in an opening direction about a catch rotation axis toward an open position of the lock unit in which a first recess of the catch is configured to receive a striker of the vehicle. Additionally, the catch includes a second recess disposed before the first recess in the opening direction. A pawl including a slot rotatable about a fixed pawl pivot axis is biased toward both the catch and the pawl pivot axis. The pawl includes a blocking arm which extends into the second recess of the catch when the lock unit is in a secondary latched position.
