摘要

The invention relates to a device for producing hot air curtains for door openings, specially in local transit vehicles, whereby said hot air curtain forms a barrier against incoming cold air in the area behind the door opening (1) and covers an area between the bottom end of the door opening (1) and another area above it. The height limit (hS) of the hot air curtain above the bottom end of the door opening (1) ranges between a minimum of one third and a maximum of one half of the total height (hG) of the door opening (1).
