Abstract
A powered deployable spoiler assembly includes a support member adapted for mounting to a motor vehicle and a spoiler panel disposed in a recessed segment of the support member. A pair of power-operated drive units interconnect the spoiler panel to the support member and are operable to move the spoiler panel between a non-deployed position, a first deployed position to provide aerodynamic assistance at a first vehicle speed, and a second deployed position to provide augmented aerodynamic assistance at a second higher vehicle speed. Each drive unit defines a guide slot and includes a stanchion fixed to the spoiler panel and a follower assembly fixed to the stanchion and disposed for movement within the guide slot. Electric motors are coupled to rotary-to-linear conversion mechanisms for converting rotation into translation of the follower assemblies to control movement of the spoiler panel.
