According to an example a dampening system for a hinged component may include a spring having a first end hooked onto a chassis and a second end hooked onto to a strap, in which the strap is connected to the hinged component. The dampening system may also include a curved guide element attached to the chassis, in which the spring is to bend around a portion of the curved guide element as the strap is moved from a first position to a second position.
