The pad is configured to cover the exposed child contact areas of a safety seat and is releasably secured to the seat by adhesive strips positioned on the base layer. Perforation lines are provided on a seat back portion of the pad and on a seat bottom portion of the pad. The perforations are opened to provide apertures for connecting safety harness webbing to safety seat anchor points. ## Claims ### Claim 1 A disposable absorbent pad for a child safety seat, the pad

base layer adjacent the periphery of each seat back bolster flap. ### Claim 4 (depends on 3) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 3, the seat back bolster flaps being separated from the seat bottom bolster flaps by a V-shaped notch. ### Claim 5 (depends on 1) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 1 further including seat back bolster flaps extending from the seat back portion, the seat back bolster flaps being dimensioned to overlie side portions of the seat back, the fastener being positioned on the base layer adjacent the periphery of each seat back bolster flap. ### Claim 6 (depends on 1) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 1 wherein the back perforations extend along a pair of parallel lines, whereby the back perforations may be separated to provide apertures registered with selected safety seat harness anchor points. ### Claim 7 (depends on 1) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 1 further including a plurality of overwraps extending from the seat back portion, the overlaps being separated from one another by a V-shaped notch, and a fastener positioned on the base layer adjacent the periphery of each overwrap. ### Claim 8 (depends on 1) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 1 further including a child safety seat, the pad being positioned on the safety seat and being releasably secured thereto by the fastener. ### Claim 9 (depends on 8) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 8 further including bolster flaps extending from the seat bottom portion, the bolster flaps overlying side portions of the child safety seat, the fastener being positioned on the base layer adjacent the periphery of the bolster flaps. ### Claim 10 (depends on 1) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 1 wherein the pad has a thickness in the order of 2 mm to 10 mm. ### Claim 11 A disposable absorbent pad for a child safety seat, the pad being dimensioned to overlie the bottom and back of the child safety seat, the pad comprising a liquid permeable outer layer, a core of liquid absorbent material and a base layer of liquid impermeable material, the pad having a seat bottom portion adapted to overlie the bottom of the child safety seat, a seat back portion adapted to overlie the back of the child safety seat and a fastener for releasably securing the pad to the child safety seat, the pad further including a pair of parallel lines of back perforations extending through the seat back portion and bottom perforations extending through the seat bottom portion, the pad being constructed so that each of the pair of parallel lines of back perforations connects to at least one bottom perforation, the bottom and back perforations being configured to be selectively separable so as to form a plurality of apertures through either the seat back portion or the seat bottom portion or to form at least one aperture through both the seat back portion and the seat bottom portion, each aperture allowing for safety harness webbing to pass therethrough. ### Claim 12 (depends on 11) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 11 wherein the fastener comprises an adhesive strip positioned on the base layer. ### Claim 13 (depends on 11) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 11 wherein the bottom perforations extending through the seat bottom are formed in a pair of divergent lines. ### Claim 14 (depends on 13) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 13 wherein each of the parallel lines interconnects with one of the divergent lines. ### Claim 15 (depends on 11) A disposable absorbent pad for a child safety seat as constructed in accordance with claim 11 further including a child safety seat having a seat bottom, a seat back and safety harness webbing, the pad being releasably secured over the safety seat with the safety seat harness webbing extending through a pair or apertures formed by separated back perforations in the seat back portion of the pad and a pair or apertures formed by separated bottom perforations in the seat bottom portion of the pad. ### Claim 16 A method of containing liquid spills or diaper leakage on a child safety seat having a bottom and a back, the method comprising the steps of: a) providing a disposable absorbent pad comprising a liquid permeable outer layer, a core of liquid absorbent material and a base layer of liquid impermeable material, the pad having a seat bottom portion adapted to overlie the bottom of the child safety seat and a seat back portion adapted to overlie the back of the child safety seat, the pad also comprising back perforations extending through the seat back portion of the bad and bottom perforations extending through the seat bottom portion of the pad, the pad being constructed so that at least one back perforation connects to at least one bottom perforation, b) placing the pad over the bottom and the back of the child safety seat, c) separating at least one of the bottom perforations and at least one of the back perforations to form at least one aperture through both the back and bottom portions of the pad, d) passing safety harness webbing through the at least one aperture, and e) releasably fastening the pad to the child safety seat. ### Claim 17 A disposable absorbent pad for a child safety seat, the safety seat having a bottom, a back, and a safety harness, the pad having a bottom portion dimensioned to overlie the bottom of the child safety seat, the pad also having a back portion dimensioned to overlie the back of the child safety seat, the pad comprising a liquid permeable outer layer, a core of liquid absorbent material, a base layer of liquid impermeable material and a fastener for releasably securing the pad to the child safety seat,
