Kitchen cupboards with innrt shelves that lower/descend

Hello. Has anyone come across a kitchen company in Brussels selling kitchen cupboards with shelves that descend. (I don't know what the correct term for them is in English, never mind French or Flemish!) They are designed for tall, narrow kitchens, so that the actual cupboard can be up high, but one can reach the contents by virtue of the fact that the interior shelves lower down to human height on a sort of ratchet. (Not sure if rachet is correct term btw.) Anyway, if anyone has seen anything similar, please could you kindly post where? Thank you very much indeed in advance for info of any sightings/recommendations.
