Two panels vehicle roof

An opening in the roof is covered by a front and a rear plate, one of which slides and pivots. Either front (14) and/or rear plate (15) are pivoted with their front edges (16,17) about their rear edges (18,19) into ventilation position. The rear plate slides from its angled ventilation position into open position under the closed front plate, by moving forward while still in angled position until on the last part of its movement, its rear edge (19) is lowered to move under the front plate.
