Abstract
Abstract A ski binding which is provided with a ski brake for slowing down or stopping a ski which has separated from the boot of a skier, comprising a brake member pivotable about an axis adjacent to and along one lateral edge of the ski and in an inactive nonbraking position directly or indirectly engaging with the lower side of the boot sole and especially with the lower side of a sole plate which is separated from the ski only if a strong force acts upon the boot, and spring means for pivoting the brake member to its braking position when released from the boot.

Claim 1
Independent Claim
422 words
A ski binding having a ski brake for braking a ski on a snow surface after the ski has separated from a boot of a skier comprising: a first part connectible to a ski boot so as to be movable with said boot during movement of said boot from a normal skiing position on said ski to a non-skiing position, a second part lockingly engageable with said first part when said first part and boot are in said skiing position, safety release means for holding said second part in locking engagement with said first part to maintain said first part and boot in said skiing position when normal skiing forces act upon said boot, said safety release means including means for automatically releasing said second part from said first part in response to predetermined excessive forces on said boot so as to permit said boot and first part to move away from said skiing position, a brake member, bearing means for pivotably mounting said brake member on said ski adjacent to and along a longitudinal edge thereof so as to be pivotable about an axis extending substantially in the longitudinal direction of the ski, resilient means acting on said brake member to pivot said brake member from an inactive non-braking position toward a braking position, and brake member locking means movable with said first part for locking said brake member in said non-braking position when said first part is in said normal skiing position and for permitting movement of said brake member to said braking position when said first part is away from said normal skiing position, said brake member locking means being engageable with a locking projection connected to a pivot shaft forming part of said brake member for locking said brake member in said nonbraking position, wherein said brake member and said safety release means are positioned on said ski at the same end of a boot being held by said binding, and wherein said brake member includes a substantially shovel shaped part having an inner surface in facing surrounding relationship to a portion of said safety release means when said brake member is in said non-braking position and an outer surface which is engageable with the snow when said brake member is in said braking position, said brake member being configured such that the entire longitudinal extent of said inner surface of said shovel shaped part is spaced from and in facing relationship to portions of said safety release means when said brake member is in said non-braking position.
