Abstract
A hinge assembly for use in mounting an auxiliary seat on a vertical body wall of a vehicle such as a pickup truck extended cab. The hinge assembly comprises a seat-half banana hinge member and a body-half bracket hinge member for rotating the auxiliary seat between a first vertical stowed position and a second horizontal seating position. The bracket hinge has a pair of vertically extending side walls each formed with an oblique guide slot so as to movably support one end of a spring rod for reciprocal travel therein. A cam track having forward and rear notched detents is formed on each bracket hinge member side wall and is adapted for capturing a respective one of a pair of cam followers mounted adjacent each end of the spring rod. An overcenter tension spring urges the cam followers into rolling engagement with their associated jump motion cam track providing quick-return capture of the followers into their associated forward or rear notched detents.
