Ultralight front jaw

A front jaw for a touring ski binding, comprising:

• a base;
• at least one recess or transit opening in the base;
• two lateral sole retainers which lie opposite each other in relation to a longitudinal axis of the front jaw and comprise a boot retainer pin each and which, in a pivoted-in state, co-operate with complementary bearings formed on a ski boot, in order to define a pivoting axis for the ski boot which extends substantially transverse to the longitudinal axis of the front jaw, and which can be adjusted between the pivoted-in state, in which the complementary bearings of the ski boot engage with the boot retainer pins, and a pivoted-away state in which the complementary bearings of the ski boot no longer engage with the boot retainer pins;
• spring elements for tensioning the lateral sole retainers;
• and
• a tensioning lever for moving the sole retainers from the pivoted-in state to the pivoted-away state in which they release the ski boot from a downhill skiing position or a walking position;
• wherein the at least one recess or transit opening is covered by one or more covers;
• wherein the cover/covers comprise(s) an at least substantially all-round circumferential edge and/or one or more rib-shaped reinforcements on a lower side facing away from a ski boot sole, wherein said circumferential edge and/or reinforcement/reinforcements form(s) a contact area of the cover on an upper side of the recess or the surface of the ski facing the cover;
• and
• wherein regions of the cover/covers between the contact area of the circumferential edge and/or the one or more reinforcements form elastic membrane regions which prevent snow, ice or dirt from accumulating on the surface of the cover/covers.

A front jaw for a touring ski binding, the front jaw comprising:

• a base;
• two lateral sole retainers which lie opposite each other in relation to a longitudinal axis of the front jaw and comprise a boot retainer pin each and which, in a pivoted-in state, are engaged with complementary bearings formed on a ski boot, in order to define a pivoting axis for the ski boot which extends substantially transverse to the longitudinal axis of the front jaw, and which can be adjusted between the pivoted-in state, in which the boot retainer pins are engaged with the complementary bearings of the ski boot, and a pivoted-away state in which the engagement is released;
• spring elements for tensioning the lateral sole retainers;
• a tensioning lever for moving the sole retainers from the pivoted-in state to the pivoted-away state in which they release the ski boot;
• an axial abutment which is arranged in front of the boot retainer pins in the latching direction and comprises a rearward abutting area for the sole of the ski boot,
• wherein a thermoplastic elastomer forms the abutment so that the abutment is elastically deformable.
