Patent ID: 8683665

Claim:
An adjustment system comprising: an elongated adjustment strip having two longitudinal sides, a plurality of gears extending along the strip, each gear having a support and a top surface, the support having an indentation in a middle section thereof; a base having at least one bracket that comprises a flexible arm connected to at least one tooth, wherein each tooth has a forward side facing a forward direction and a rearward side facing a rearward direction, wherein a length of each of the forward sides is greater than a length of each of the rearward sides so that an angle created between a longitudinal axis of the base and the forward side is less than an angle between the longitudinal axis and the rearward side of each tooth; wherein the strip and the base are adapted to be connected to each other by sliding the gears into the brackets so that the top surfaces of the gears are disposed between the base and the tooth of the at least one bracket, and wherein the at least one bracket is adapted to flex under a first minimum amount of force to allow the bracket to move along the strip in the forward direction to a desired position in which the tooth rests in the indentation of one of the supports when less than the first minimum amount of force is exerted, and wherein the bracket is adapted flex further under a second minimum amount of force that is greater than said first minimum amount of force to allow movement in the rearward direction.
