SAFETY CUSHION MAT AND MANUFACTURING MOLD THEREFOR
An embodiment of the invention provides a safety cushion mat that includes an inner filler made of a synthetic resin expanded foam member, and a first sheet and a second sheet which cover an upper and a lower surface of the inner filler, respectively. The inner filler may have air outlets formed in its upper and lower surfaces in a particular pattern. The first sheet may include a first sheet body portion and a first edge portion, and the second sheet may include a second sheet body portion and a second edge portion. The second edge portion may be fused with the first edge portion of the first sheet. When the first sheet and the second sheet are fused onto both sides of the inner filler, any air remaining between the first and second sheets and the inner filler may be discharged through the air outlets of the inner filler.
