Description for patent and HGM registration.

With Sioherheite toe pieces for safety ski bindings, which mostly consist of parts that can be swiveled one to the other, is a locking device when a preferably adjustable torque is exceeded when pivoting free. The requirement for shock absorption occurs more and more frequently, i.e. when cornering is not dangerous Side bumps as they should occur the Sioherheite toe piece elastically and then but return to its normal position. Here, the safety of the ski guide is up to a swivel angle by cn. 10 ° not impaired

With known safety front bars, e.g. a spring piston principle, in which a piston is guided in a bore, is pressed with the help of a strong helical spring against an approximation of the part attached to the oil,

or btl another version, in which at least one of the ropes that can be swiveled against each other old him associated rope of the locking device is connected by means of an elastic joint, are shock-absorbing, work but on a different principle.

The invention is based on the object of a ßtofldämpfenden To create safety Yordtrbaoken, the opposite These designs have essential parts of the door. In the case of the invention, safety front bars are thereby achieved achieved that a suspension system z'indet use, which maintains a set torque without any significant increase in force up to a pivoting angle of approx. 30 °. Sas suspension system allows you to set different Torques and is designed so that as the spring force increases, the lever arm decreases. This is advantageous in a wide variety of security front bar designs install and superfluous Every use of locking devices, always has a sufficiently large return force, thus has an enormous shock-absorbing effect and can in most cases be used in such a way that an automatic Provision given let

The Fedex system according to the invention consists of two mirror-image angle levers with a common pivot point and a common stop bolt · Xn a at a certain distance from the pivot point, the two angle levers are connected by a preloaded helical spring, so that both angle levers rest against the soleplate with the same torque,

According to another feature of the invention, the two are known Very robes, through which the Sohrauben feathers on the two angle levers are attached, a ball head and the angle lever a spherical recess.
