1. A covering assembly for a side sill (16) of a passenger motor car, comprising:
a sill cover (20) which comprises a first covering element (22) that is arrangeable under a door opening (18) in a longitudinal area (L) of the side sill (16) and a second covering element (24) that is arrangeable under the door opening (18) in the longitudinal area (L); and
a drive unit (A), wherein via the drive unit (A) the first covering element (22) is pivotable around a first pivot axis (S1) and the second covering element (24) is pivotable relative to the side sill (16) between a covering position (V) and a convenience position (K) around a second pivot axis (S2) that is spaced apart from the first pivot axis (S1) and runs parallel to the first pivot axis (S1);
wherein the drive unit (A) is a spindle drive (30) which comprises a motor (34) that is shared with the first and second covering elements (22, 24), a spindle (32) that is shared with the first and second covering elements (22, 24) and is rotatable by the motor (34), and a driving element (36) that is shared with the first and second covering elements (22, 24) and is screwed onto the spindle (32);
wherein the driving element (36) is slidable along the spindle (32) via rotation of the spindle (32) relative to the driving element (36) such that the first and second covering elements (22, 24) are pivotable.
