ABSTRACT:
A retractable step assist for a vehicle comprises a step, an actuator, an optical fiber sensor, and a safety. The step is movable between a retracted position and a deployed position that is downward and outboard from the retracted position. The actuator is mechanically connected to the step to position the step. The optical fiber sensor has an output that varies when pressure is applied to the optical fiber sensor. The safety is triggered by this output from the optical fiber sensor. The safety is configured to terminate retraction of the step when the optical fiber sensor senses pressure from an object pinched by the step deck.
