Abstract: An accessory for supporting a handheld electronic device includes a bistable spring to position and support the handheld device. The accessory includes a housing coupled to the handheld device and a bistable spring moveable between a first position and a second position. In the first position the bistable spring is substantially flat and in the second position the bistable spring defines a longitudinal curve away from the housing. The curvature of the bistable spring in the second position can support the handheld device on a surface e.g. table and in a slot such as CD player or air vent in a vehicle. The longitudinal curve of the bistable spring easily deflects to a reduced curvature to be received in and retained with a slot and consistently actuates to same radius in the second position providing proper viewing angle of screen for handheld device.
