Abstract (en)
[origin: EP0345222A2] The grating has a safeguard against it springing out when it is driven over. For this purpose, one part (2') of its support element is constructed on one side surface of the grating (1) as a thin, tongue-shaped wall (33) having an outer thickening (34). The support element has an incision (35) extending perpendicular to its longitudinal axis at each end of the tongue-shaped wall (33), a thickening (22) and/or an indentation being present on one inner side surface of the associated support frame (2, 2'). <IMAGE>
