This invention relates to attachments for protecting the upper surfaces of rear portions of skis. It is known to secure attachments to the upper surfaces of rear portions of skis to prevent or help to prevent a person learning to ski from allowing the rear portion of a pair of skis to cross over one another, this being a common problem for ski learners. Attachments for this purpose are shown for example in U.S. Pat. No. 3,863,944 (Waddel) issued Feb. 4, 1975 and U.S. Pat. No. 3,885,805 (Solymosi) issued May 27, 1975. However, attachments such as those mentioned above are not intended to cope with another problem which can affect all skiers, namely the likelihood of the following skier in a line up or a ski tow inadvertently moving forward in the line up too soon so that the front portions of the skis of the following skier ride up over and damage the upper surfaces of the rear portions of the skis of the person in fromt in the line up. In addition to the physical difficulty likely to be caused to the skier in front, there is also the likelihood of the rear portions of the skis of the skier in front being scratched by the front portions of the following skis, with unsightly results which are especially unwanted if the skis are of the expensive kind. It is therefore an object of the invention to provide an attachment for the upper surface of the rear portion of a ski which is especially effective in preventing or helping to prevent problems such as those mentioned above caused by a following ski. According to the present invention, a ski attachment comprises a rigid body of hard impact resistant material having a base securable to the upper surface of a rear surface of a ski, said body being generally triangular in side view with a substantially flat rear face extending upwardly and forwardly from a rear base edge at an angle in the range of from about 35.degree. to about 50.degree. to the upper surface of the ski when the attachment is secured thereto to a vertical height above the upper surface of the ski when the attachment is secured thereto in the range of from about 0.375 to about 0.875 inches. The body may have substantially flat generally triangular side faces at opposite ends of the rear face which are upwardly and laterally inwardly inclined to the upper surface of the ski when the attachment is secured thereto at an angle in the range of from about 60.degree. to about 85.degree.. The side faces may diverge in a forward direction when the body is attached to the upper surface of the ski with an included angle in the range from about 5.degree. to about 15.degree.. The body may be a rigid body of hard impact resistant synthetic plastic material with said substantially flat rear face, a substantially flat base face, a substantially flat front face extending downwardly and forwardly from an upper edge of the rear face to a front face edge, and substantially flat generally triangular side faces extending between the base, rear and front faces at opposite ends of the body.
