Claim:
1. An adjustable support arm, comprising: a first bracket; a second bracket configured for mounting an attached device; an upper arm having a first end and a second end, wherein the first end of the upper arm is pivotally connected to the first bracket, and wherein the second end of the upper arm is pivotally connected to the second bracket; a lower arm having a first end and a second end, wherein the first end of the lower arm is pivotally connected to the first bracket, and wherein the second end of the lower arm is pivotally connected to the second bracket; a first link having a first end and a second end, wherein the first end of the first link is pivotally connected to the upper arm to define a first pivot point in the upper arm about which the first link pivots; a second link having a first end and a second end, wherein the first end of the second link is pivotally connected to the lower arm to define a second pivot point in the lower arm about which the second link pivots, and wherein the second end of the second link is pivotally connected to the second end of the first link by a fastener to form a V-shaped linkage defining a vertex and an open end, with the V-shaped linkage oriented such that the vertex is positioned more proximate to the second bracket than the open end; and a biasing member positioned between the upper arm and the lower arm, wherein a first end of the biasing member is connected to the first end of the upper arm, and wherein a second end of the biasing member is connected to the vertex of the V-shaped linkage.
