Abstract
An assist handle assembly for a vehicle includes a body and at least a first hinge assembly rotatably coupled to the body. A primary spring interconnects the body and the first hinge assembly and biases the body from an open position into a stowed position. A secondary spring interconnects the body and the first hinge assembly, and biases against the primary spring when the body is between the open position and an intermediate position to resist rotation of the body into the stowed position, and biases with the primary spring when the body is between the intermediate position and the stowed position to assist rotation of the body into the stowed position.
