A motor driven assembly for a door, e.g. vehicle door, comprises a rotatable vertical support post 7 mounted to the frame with arms 11 having a spindle 15 sliding within a track (21, fig.1) on the door; rotation of post 7 rotates door between closed and semi-open position. Door 1 is movably supported to the frame by an arm 49 and driven open/closed by cooperation of a drive bracket 47, drive pin 43 and drive belt 41. Preferably the drive pin 43 locates in an arcuate slot (44) of drive bracket 47 to provide lost motion during initial swinging of the door and delaying linear sliding movement. Also claimed is an assembly where a second drive pin 45 fixed to belt 41 rotates plate 55 via open slot, plate 55 being fixed to vertical post 7 to rotate the door between closed and semi-open position. After initial rotation pin 45 exits slot in plate 55 which may be held in place by a latch until closing.
