AI summary

The ventilation air guiding grid has frame sections (1) which are spaced apart and are arranged opposing each other. Two air deflectors (2) are mounted on the frame sections and mutually positioned in parallel, where the ends of the air deflectors are rotatable about its respective axis of rotation. The deflectors are connected via a coupling element such that interconnection position of the deflectors is varied upon displacement of the coupling element.
