Abstract:
1. A safety binding device for binding a boot on an alpine ski, said binding device comprising: a releasable retaining mechanism for the boot, said retaining mechanism being actuable to a release position in response to a force to which the boot is subjected; said releasable retaining mechanism comprising an arrangement to detect the force to which the boot is subjected while the boot is retained by said releasable retaining mechanism; an electronic circuit controlling said release of said releasable retaining mechanism by generating a release command as a function of a detected magnitude of said force and as a function of a duration Δt of force; said release occurring in response to said detected magnitude of said force being greater than an actual release threshold Sr; said release threshold being dependent upon the duration Δt of force; said duration Δt of force being greater than one second; the actual release threshold Sr being comprised between 50% and 75% of a theoretical release threshold St, whereby: the theoretical release threshold St is determined as a function of a skier's parameters in conformance with ISO standards.
