Abstract
Abstract A releasable ski binding device is disclosed whereby the release mechanism is electrically actuated by signals generated by a plurality of pressure sensor mounted in proximity to a ski boot. The binding device includes heel and toe engaging members and a solenoid actuated release mechanism having a learning system which automatically increases or decreases the pressure threshold point at which the release mechanism will be actuated. The device of this invention assures a skier that the ski binding will release only if excessive abnormal pressures are exerted and will not inadvertently release under conditions normal to the skier, even if the norm varies throughout the skiing day.
