Fifth wheel hitch

摘要

An adjustable fifth wheel hitch for towing a trailer behind a motor vehicle includes a support frame having a pair of spaced guide rails. A head assembly for engaging the trailer is coupled to the support frame through an adjustment assembly so as to be selectively displaceable between a towing position and a maneuvering position. A locking assembly releasably locks the head assembly in the towing and maneuvering positions. The locking assembly includes a locking arm positionable in a locked position, which is engaged with one of the pair of spaced guide rails, and an unlocked position. The locking arm includes a camming surface that cooperates with a locking cam so as to position the locking arm in the locked position and the unlocked position.
