Abstract
A steering lock locks a steering member with a lockbolt movable along an axis between locking and unlocking positions. A first member having a first cam surface is rotatable by an actuator in a first direction for locking the lockbolt. A second member having a second cam surface is engaged with the first cam surface. The second member is translatable along the axis in a locking direction by rotation of the first member. An unlocking spring is compressible through a range of movement of the second member in the first direction to store increasing potential energy. The cam surfaces are engaged such that unlocking of the lockbolt is carried out by the stored energy in the unlocking spring, which is released in a continuously increasing manner controlled by the actuator as the first member is rotated by the actuator in a second direction opposite the first direction.
