Abstract: A vehicle top carrier having guide members rigidly mounted on top of the vehicle, a load carrying frame mounted on the guide members for movement from a generally horizontal position atop the vehicle to an inclined loading and unloading position displaced from the vehicle, and a support arm assembly pivotally mounted at each end respectively to one end of the carrier frame and a vertical surface on the vehicle. The support arm assembly includes a pair of pivotally joined segments releasably secured in a rigid and generally linear relationship to each other. After the carrier frame has been slidably displaced to a partially inclined position, the support arm segments are released from their locked engagement with each other and are allowed to pivot about their adjoining ends, resulting in further inclination of the carrier frame to a more accessible loading and unloading position.
