(57) 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.
