A ski brake, which is mounted on the ski and provided with two brake arms, one on each side of the ski, which brake arms by spring action can be turned to a catching position, in which the brake arms extend downward, substantially perpendicularly to the ski. The invention is characterized in that the ski brake consists of single piece of material, and the resilience is obtained by utilizing the design of the sheet metal material, a.o. reinforcing grooves.

A ski brake, comprising: a bottom plate made from flexible sheet material which in its turn comprises an attachment plate portion adapted to be mounted on the upper surface of a ski and a thrust plate portion structurally integral with the attachment plate portion and two brake arms connected to and integral with the thrust plate portion and located in the same plane as on both sides of the thrust plate portion, which brake arms by spring action between said two plate portions can be turned to a braking position, in which the brake arms extend downwardly to a position below the ski, characterized in that the bottom plate consists of a single piece of thin sheet metal, which is provided with longitudinal deformation grooves extending between and into both plate portions in the longitudinal direction of the ski, the bottom plate in unloaded state is bent transversely to the longitudinal direction so that an angle is formed between the attachment plate portion and the thrust plate portion, that the bottom plate is elastically flexible against its own resilience enabling it to be flexed to a substantially plane condition, and that the sheet metal material along said brake arms and extending between said brake arms across said thrust plate portion has a deformation contour providing stiffness in said thrust plate portion and said brake arms.
