         4 . The heel piece according to  claim 1 , wherein the ski brake comprises an actuating plate, the upper side of which is embodied such that it is pressed downwards or towards the ski by the sole of the ski boot when a user steps into the heel piece, thus pivoting the brake arms from a braking position to a travelling position. 
     
     
         5 . The heel piece according to  claim 4 , wherein the sole of the ski boot, in particular the lower side of the sole of the ski boot, rests against the contact surface when the brake arms are in the travelling position. 
     
     
         6 . The heel piece according to  claim 4  , wherein the brake arms are formed by a shaped wire part which is mounted on the actuating plate such that it can rotate about a first rotational axis, wherein the first rotational axis is for example arranged in front of the front end of the base plate when the brake arms are in the travelling position or the actuating plate is pressed downwards. 
     
     
         7 . The heel piece according to  claim 6 , further comprising a pivot arm which is mounted on the actuating plate such that it can rotate about a second rotational axis and on the base plate such that it can rotate about a third rotational axis. 
     
     
         8 . The heel piece according to  claim 7 , further comprising a spring, for example a torsion spring, which biases the pivot arm in relation to the base plate such that it moves the actuating plate upwards when a user steps out of the heel piece wearing the ski boot or moves the brake arms from the travelling position to the braking position. 
     
     
         9 . The heel piece according to  claim 1 , wherein the brace height measures between 6 and 15 mm, for example between 10 and 15 mm, wherein the brace height is the vertical distance between the upper side of the ski or lower side of the base plate and the contact surface. 
     
     
         10 . The heel piece according to  claim 1 , wherein the base plate comprises a plate body made of plastic and a reinforcing structure, for example an insert made of metal, which is inserted into the plate body and at least partially encompasses a pivot axis or pivot axis portions of the brake arms. 
     
     
         11 . The heel piece according to  claim 10 , wherein the reinforcing structure is inserted into the plate body from the lower side and fastened to the plate body in a positive fit and/or in a force fit. 
     
     
         12 . The heel piece according to  claim 1 , wherein the base plate or the portion of a plate body of the base plate which forms the contact surface, wherein the plate body is for example made of plastic, comprises an opening on each of its two sides, wherein the opening is in particular groove-shaped and is open towards the lower side of the plate body or towards the upper side of the ski and through each of which a pivot axis portion of the ski brake extends outwards, wherein the opening which points towards the lower side is preferably covered by the upper side of the ski when the heel piece is mounted on the ski. 
     
     
         13 . The heel piece according to  claim 1 , wherein the base plate mounts the brake arms or pivot axis portions of the brake arms such that they can pivot about a pivot axis, wherein the pivot axis is arranged in the lower half, or the half pointing towards the upper side of the ski, of the portion of the base plate or the portion of a plate body of the base plate which forms the contact surface. 
     
     
         14 . The heel piece according to  claim 1 , wherein the rear third or rear quarter of the base plate comprises rear transit holes, which are in particular arranged on both sides of threaded segments which a threaded spindle of the base body engages, for receiving rear fastening screws. 
     
     
         15 . The heel piece according to  claim 1 , wherein the base plate comprises front transit holes, in the front half outside the contact surface, for receiving front fastening screws, wherein the front transit holes are preferably arranged directly behind the contact surface and/or such that the base body, for example a first guide element and a second guide element, can be slid over the front transit holes and the front fastening screws. 
     
     
         16 . The heel piece according to  claim 1 , wherein the base plate comprises front transit holes for receiving front fastening screws in the contact surface, wherein the front transit holes are arranged in the immediate vicinity of the pivot axis portions. 
     
     
         17 . The heel piece according to  claim 13 , further comprising a reinforcing insert which is for example made of metal and which is inserted into the front transit holes, wherein the reinforcing insert comprises for example annular portions, which are inserted into the front transit holes, and a connecting portion which connects the annular portions, wherein the connecting portion preferably comprises a U-shaped portion into which a pivot arm of the ski brake is pivoted when the ski brake is moved into the travelling position, and out of which the pivot arm is pivoted when the ski brake is moved into the braking position. 
     
     
         18 . The heel piece according to  claim 1 , wherein the heel piece is part of an alpine ski binding or an alpine heel.
