Abstract
Abstract A safety ski binding of the type incorporating at least one securing head into which there can be inserted the ski boot, this securing head being raisable at the side of the ski boot and incorporating two retaining arms, the free ends of which hold or secure the ski boot, these retaining arms being laterally pivotable for the purpose of releasing the ski boot. According to important aspects of the invention the securing head is equipped with a latching or locking mechanism which fixes the securing head in its lowered position, such latching mechanism engaging with predetermined locations of said retaining arms. The latching mechanism is subjected to the counter force of at least one spring member, so that upon exceeding the adjusted force this spring member releases the latching mechanism and therefore the securing head.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A safety ski binding comprising at least one securing head, means for pivotably mounting said securing head to be raisable at the side facing the ski boot of a skier to facilitate insertion of such ski boot into the ski binding, a pair of laterally pivotable retaining arm members carried by said securing head and having free ends for holding the ski boot and laterally pivotable for releasing such ski boot, a locking mechanism provided for said securing head positioned to cooperate with said retaining arm members for fixing said securing head in a lowered position, said locking mechanism being engageable with predetermined regions of said retaining arm members, at least one spring means provided for said securing head for exerting a counter force upon said locking mechanism, so that when a force is applied to the ski binding which exceeds the adjusted force of said spring means, said spring means releases said locking mechanism and therefore said securing head.
Claim 2
Dependent Claim
160 words
A safety ski binding comprising at least one securing head, means for pivotably mounting said securing head to be raisable at the side facing the ski boot of a skier to facilitate insertion of such ski boot into the ski binding, a pair of laterally pivotable retaining arm members carried by said securing head and having free ends for holding the ski boot and laterally pivotable for releasing such ski boot, a locking mechanism provided for said securing head positioned to cooperate with said retaining arm members for fixing said securing head in a lowered position, said locking mechanism being engageable with predetermined regions of said retaining arm members, at least one spring means provided for said securing head for exerting a counter force upon said locking mechanism, so that when a force is applied to the ski binding which exceeds the adjusted force of said spring means, said spring means releases said locking mechanism and therefore said securing head.
Claim 3
Dependent Claim
57 words
A safety ski binding as defined in claim 1, wherein said spring means exerting a counter force upon said locking mechanism simultaneously acts upon said retaining arm members to exert a counter force upon said retaining arm members, said counter forces being responsive to forces exerted on the ski binding in the lengthwise and transverse directions thereof.
Claim 4
Dependent Claim
42 words
A safety ski binding as defined in claim 1, wherein said locking mechanism incorporates two rotatably mounted pawl members engageable with said securing head, and an intermediate member for spacedly positioning said pawl members when the latter engage with said securing head.
Claim 5
Dependent Claim
38 words
A safety ski binding as defined in claim 3, further including means for adjusting the width of said intermediate member, a pressure-actuated tiltable lever at which said intermediate member is arranged and serving for releasing said locking mechanism.
Claim 6
Dependent Claim
48 words
A safety ski binding as defined in claim 3, further including means defining recesses forming said predetermined regions of said retaining arm members, each said pawl member being mounted to assume a locking position in which it engages with the associated recess of the associated retaining arm member.
Claim 7
Dependent Claim
50 words
A safety ski binding as defined in claim 3, wherein each pawl member is constructed as a double-arm lever member, one arm of which bears against said intermediate member and the other arm of which bears against its associated retaining arm member for the purpose of introducing said intermediate member.
Claim 8
Dependent Claim
54 words
A safety ski binding as defined in claim 3, wherein said means for pivotably mounting said securing head comprises an attachment plate member for rotatably supporting said securing head, web means arranged between said retaining arm members for rotatably mounting said pawl members, said web means being fixedly connected with said attachment plate member.
Claim 9
Dependent Claim
56 words
A safety ski binding as defined in claim 1, wherein said locking mechaNism comprises web means arranged between said retaining arm members, said web means being provided with recesses, each of said retaining arm members having a nose member engageable with an associated recess of said web means when said securing head assumes its lowered position.
Claim 10
Dependent Claim
70 words
A safety ski binding as defined in claim 8, further including a guide plate connectable with the upper surface of the ski, bracket means for mounting said web means at said guide plate, a tiltable lever, pin means pivotable by means of said tiltable lever and engaging with said bracket means, whereby upon pivoting of said tiltable lever said web means is displaceable through the agency of said pin means.
