Abstract
Abstract A heel retainer for a safety ski-binding comprises a housing for attachment to the ski and a holder for engaging the sole of a ski boot. The sole holder is pivoted to the housing by a shaft displaceable in slots of the housing extending substantially parallel to the ski and is held in a sole-engaging or sole-releasing position by a first spring. A second spring biases the pivot shaft in the slots towards the ski tip. A pivotable entrainment member for the sole holder is engaged by said first spring. The sole holder is suspended from the entrainment member by a pin and slot connection.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
194 words
A heel retainer for a safety ski-binding, comprising a supporting member, means for fixing said supporting member to a ski, a sole holder, means for pivoting said sole holder to the supporting member about a horizontal transverse shaft and means for displacing said sole holder in slots substantially parallel to the ski, said sole holder comprising a closing pedal, a first spring means positioned between the sole holder and supporting member for keeping the sole holder in the operative or open position, a handle means for deliberately relieving the sole holder, and a second spring means for biassing said transverse shaft of the sole holder at least approximately in the direction of the slots in the supporting member towards the ski tip, wherein said supporting member comprises a housing and an entrainment member means for the sole holder, a horizontal transverse pivot shaft, means for pivoting said entrainment member means about said pivot shaft, suspending means for suspending said sole holder from said entrainment member means comprising a slot and a horizontal transverse pin respectively provided on said sole holder and entrainment member means, wherein said first spring means engages said entrainment member means.
Claim 2
Dependent Claim
194 words
A heel retainer for a safety ski-binding, comprising a supporting member, means for fixing said supporting member to a ski, a sole holder, means for pivoting said sole holder to the supporting member about a horizontal transverse shaft and means for displacing said sole holder in slots substantially parallel to the ski, said sole holder comprising a closing pedal, a first spring means positioned between the sole holder and supporting member for keeping the sole holder in the operative or open position, a handle means for deliberately relieving the sole holder, and a second spring means for biassing said transverse shaft of the sole holder at least approximately in the direction of the slots in the supporting member towards the ski tip, wherein said supporting member comprises a housing and an entrainment member means for the sole holder, a horizontal transverse pivot shaft, means for pivoting said entrainment member means about said pivot shaft, suspending means for suspending said sole holder from said entrainment member means comprising a slot and a horizontal transverse pin respectively provided on said sole holder and entrainment member means, wherein said first spring means engages said entrainment member means.
