A hinged panel ( 110 ) coupled to a body member ( 120 ), for example in a wireless communications device, including a torsion spring ( 150 ) coupled to the body member and to the panel, a cam ( 127 ) coupled to the body member, a follower ( 134 ) coupled to the panel. A decreasing counter-torque is applied to the panel by the spring biased cam and follower assembly when the torsion spring torque is above a specified level, and an increasing assisting-torque is applied to the panel by the spring biased cam and follower assembly when the torsion spring torque is below a specified level. |
