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.
