Abstract (en)
The invention relates to a ventilation grate provided with an air collecting housing and a front plate covering the air collecting housing, through which air can be blown from the air collecting housing. The front plate is provided with arcuate openings proceeding from a center outwards. At the rear side of the openings, an adjustable blade is provided in order to selectively guide the airflow in a cross direction with respect to the opening. The blade is of tiltable design having a bistable, curved shape so that, selectively, one of the longitudinal sides of the blade can be maintained pressed against a longitudinal side of the opening. In this manner, a simple adjustment of the ventilation grate can be provided, for, at wish, airflows directed inwards or outwards.
