A lock unit for a vehicle, the lock unit having an open position, a primary latched position, and a secondary latched position, and the lock unit comprising: a catch comprising a first recess and a second recess, and having a catch rotation axis; a pawl comprising a pawl blocking arm and having a pawl pivot axis; a blocking lever having a blocking lever rotation axis; and a rocker lever having a pivot; wherein said catch is rotatable about said catch rotation axis along a first path in an opening direction and in a closing direction, whereby the lock unit assumes the open position, the primary latched position, or the secondary latched position; said catch is biased in the opening direction about said catch rotation axis toward the open position; said second recess is disposed before said first recess in the opening direction; said pawl is biased about said pawl pivot axis toward said catch; said first recess is configured to receive a striker of the vehicle in the open position and to securely retain the striker in the primary latched position and the secondary latched position; said blocking lever is rotatable about said blocking lever rotation axis along a second path; said rocker lever is rotatable about said pivot point and intersects said first path and said second path; when the lock unit is in the primary latched position or in the secondary latched position, said blocking lever abuts said blocking arm against said catch, characterized in that when the lock unit is in the secondary latched position, said blocking arm extends into said second recess; and when the lock unit moves from a point after the secondary latched position and before the primary latched position in the closing direction, the catch actuates said rocker lever resulting in a reciprocal displacement of the blocking lever away from the pawl. a catch comprising a first recess and a second recess, and having a catch rotation axis; a pawl comprising a pawl blocking arm and having a pawl pivot axis; a blocking lever having a blocking lever rotation axis; and a rocker lever having a pivot; wherein said catch is rotatable about said catch rotation axis along a first path in an opening direction and in a closing direction, whereby the lock unit assumes the open position, the primary latched position, or the secondary latched position; said catch is biased in the opening direction about said catch rotation axis toward the open position; said second recess is disposed before said first recess in the opening direction; said pawl is biased about said pawl pivot axis toward said catch; said first recess is configured to receive a striker of the vehicle in the open position and to securely retain the striker in the primary latched position and the secondary latched position; said blocking lever is rotatable about said blocking lever rotation axis along a second path; said rocker lever is rotatable about said pivot point and intersects said first path and said second path; when the lock unit is in the primary latched position or in the secondary latched position, said blocking lever abuts said blocking arm against said catch, characterized in that when the lock unit is in the secondary latched position, said blocking arm extends into said second recess; and when the lock unit moves from a point after the secondary latched position and before the primary latched position in the closing direction, the catch actuates said rocker lever resulting in a reciprocal displacement of the blocking lever away from the pawl.
