An actuator (10) comprises a motor shaft (12), an output (18) driven by the motor shaft, a first ratchet (26), and a second ratchet (28). A first cam surface is (264) connected to rotate with the output (18), wherein the first cam surface is arranged to disengage a first ratchet pawl from a first ratchet wheel when the output is within a first predetermined angular range, and to allow the first ratchet pawl to engage with the first ratchet wheel when the output is outside the first predetermined angular range. A second cam surface (284) is connected to rotate with the output (18), wherein the second cam surface is arranged to disengage a second ratchet pawl from a second ratchet wheel when the output is within a second predetermined angular range, and to allow the second pawl to engage with the second ratchet wheel when the output is outside the second predetermined angular range.
