Apparatus and method for braking ergonomic support actuator

A braking actuator system for a seat comprising:

• an ergonomic support, wherein said ergonomic support comprises an arching pressure surface for a lumbar support;
• a first frictional surface;
• a second frictional surface, said second frictional surface having a first position in contact with said first frictional surface and a second position spaced apart from said first frictional surface by a gap;
• means for moving said second frictional surface between said first position and said second position;
• means for rotating said second frictional surface relative to said first frictional surface;
• and
• a Bowden cable comprising a wire in a sleeve;
• wherein said sleeve is fixed relative to said first frictional surface and wherein said wire is connected to said second frictional surface and imparts a force thereto from said ergonomic support to force said second frictional surface into said first position and wherein rotation of said second frictional surface moves said wire relative to said sleeve, wherein said arching pressure surface provides said force to bias said second frictional surface to said first position.

A braking actuator system comprising:

• a housing comprising a seat, a first friction surface and a mount, wherein said first friction surface further comprises a wedge angle in said seat;
• a disk comprising a second friction surface, a load edge, a wire seat and an axle, wherein said second friction surface further comprises an angle in said disk corresponding to said wedge angle in said seat, said disk further comprising a first position wherein said second friction surface contacts said first friction surface and a second position wherein a gap is between said second friction surface said first friction surface and wherein said axle slidingly and rotatingly engages with said mount;
• and
• a lever comprising a pin fixedly connected to said lever, wherein rotating said lever moves said disk away from said first friction surface and into said second position and said pin contacts said load edge and rotates said disk relative to said housing.
