A fireproof ceramic impact pad comprises, in its functional position, a bottom (10) with a lower base area (10g) and an upper impact surface (10p); and a wall having multiple segments (20a-d), which extends from the bottom (10) up to a free end (20k), wherein the wall (20) with its inside (20i) and the impact area (10p) together border a space (30) which is open at its end opposite the bottom (10). At least one segment (20a) of the wall (20) features at least one opening (40), which runs from the inside (20i) of the wall continuously to the outside (20s) of the wall (20) and which is bordered by opposite flanks (400. The opening (40) features a cross-sectional profile in which, regarding the perimeter direction of the wall (20), the opening (40) has its largest width (Bg) adjacent to the free end segment (20a); and regarding the perimeter direction of the wall (20), the opening (40) has its smallest width (Bk) adjacent to the bottom (10). The opening (40) extends along more than 40% of the height (H) of the wall (40), and the largest width (Bg) of the opening (40) is more than 5% of the total perimeter of the wall(20) of the impact pad. In a longitudinal direction, from the upper free end segment (20k) of the wall (20) vertically downwards toward the bottom, the opening (40) extends in a profile with more than 70% of its cross-section in the upper half, adjacent to the free end segment (20k) of the wall (20). |
