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 also supported to the frame by arm 49 connected to a bracket 47 driven by a drive pin 43 for linear movement of the door with lost motion delaying sliding of the door until the edge is rotated clear of the frame. Preferably bracket 47 include arcuate slot within which pin 43 locates; pin 43 is fixed to flexible drive means, e.g. belt, chain, 41. 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.
