  • Patent number: 5485900
    Abstract: An automatic brake lockout for restricting operation of a trailer hitch surge suppressor as a trailer is being backed by a pulling vehicle. The automatic brake lockout works on a two-part trailer hitch with a first member sliding toward a second member to activate the surge suppressor. When actuated, the automatic brake lockout restricts movement of the first member toward the second member to allow the trailer to be backed without the surge suppressor being actuated. Once the trailer has been adequately backed, the pulling vehicle need only move slightly forward to release the automatic brake lockout device and leave the surge suppressor operable.
