Air channel for vehicle ventilating device has boundary walls fitted to each part, and one boundary wall at least partly spaced out from base region of opposite part

摘要

The air channel has boundary walls (e.g. 18) dividing the flow cavity into several part channels. There is a boundary wall fitted to each part: upper part (12) and lower part (14). The first and second boundary walls are at least in regions spaced out from the base region (28) of the lower part. A third boundary wall is spaced out from the base region (22) of the upper part.
