A system and method for remote actuation of a vehicle head restraint includes an actuator arrangement configured to effect movement of a head restraint from a raised position to a lowered position. A sensor defines a first area, and is configured to output signals to the actuator arrangement to facilitate movement of the head restraint from its raised position to its lowered position when an object comes within a predetermined distance of the first area. The sensor is disposed proximate a rearview mirror in the vehicle such that a user can simultaneously view the head restraint in the mirror and the first area. Remote actuation systems using infrared sensor assemblies such infrared proximity sensors are disclosed.
