A vehicle seat latch ( 24 ) includes a latch member ( 40 ) and a blocking member ( 70 ) that each have associated first and second blocking surfaces ( 80, 82 and 88, 90 ) for holding the latch member in a latched position with the blocking member in a blocking position. The first blocking surfaces ( 80 and 88 ) of the latch member and blocking member have a pressure angle between 4.6 and 6.6 degrees while the second blocking surfaces ( 82 and 90 ) have a zero degree pressure angle and are slightly spaced from each other. A deformable blocking portion ( 84 ) of the blocking member ( 70 ) defines its first blocking surface ( 88 ) and is deformed by excessive loading so that the zero degree pressure angle second blocking surfaces ( 82 and 90 ) then contact each other to hold the latch member in its latched position.
