The cover unit 58 is configured for at least substantially preventing airflow from the second sub-compartment 18 into the first sub-compartment 16 through the cabling recess 56. The cover unit 58 is attachable to the divisional wall section 32, in particular to the first wall section 44 of the divisional wall section 32. The cover unit 58 is attachable to the divisional wall section 32 by two screws. The cover unit 58 at least partly encompasses the connector plug 60 of the electrical connection unit 54. In an installation position the cover unit 58 comprises a locking element 102. The locking element 102 is a form fit element. The locking element 102 is shaped at least partly corresponding to the electrical connector unit 54, in particular to the connector plug 60. The locking element 102 is in particular embodied as a locking corner.


The cover unit 58 is configured for sealing the cabling recess 56. The cover unit 58 comprises a sealing element 104. The sealing element 104 at least partly overlaps with the electrical connector unit 54, in particular with the connector plug 60, preferably in a main extension direction of the divisional wall section 32. The sealing element 104 is implemented as a bent portion of the cover unit 58. The cover unit 58 comprises a further sealing element 106. The further sealing element 106 at least partly overlaps with the divisional wall section 32, preferably in a main extension direction of the divisional wall section 32. The further sealing element 106 is implemented as a protrusion of the cover unit 58.
