Abstract: TRUCK ACTUATED VEHICLE RESTRAINT          HAVING A PIVOTABLE INCLINED SURFACE              Abstract of the Disclosure A vehicle restraint for preventing a vehicle, such as a truck, from accidentally pulling away from a loading dock during a loading operation.  The vehicle restraint comprises a mounting frame mounted on the front vertical surface of the loading dock and a slide is mounted for movement on the mounting plate and is biased to an upper position.  An inclined cam member is pivoted to the upper portion of the outer end of the slide and extends downwardly and outwardly from the slide and the lower end of the cam member is pivotally connected to the mounting frame via a link of fixed length.  When a truck backs toward the loading dock, an abutment, such as an ICC bar, at the rear end of the truck, will engage the inclined cam member, wedging the slide downwardly against the force of the biasing means, and the ICC bar will engage a notch located in the upper edge of the slide to block outward movement of the truck from the loading dock.  To release engagement of the ICC bar from the notch, a release bar is moved upwardly into engagement with the ICC bar, thereby driving the slide downwardly against the force of the biasing means to release the ICC bar and enable the truck to pull away from the dock.
