Seat restraint buckle assembly

A seat restraint buckle assembly for a seat restraint system in a vehicle comprising:

• a rigid frame having an open forward end defining a passage to receive a latch plate;
• a locking member operatively connected to said frame and pivotal between a latched position in which said locking member retains the latch plate within said passage and an unlatched position in which said locking member is held clear of said passage;
• a release button slidably mounted on said frame above said passage for longitudinal movement relative to said frame;
• a blocking lever operatively connected to said frame and pivotal to contact said locking member and urging said locking member towards said latched position when opposing forces are acting on said locking member;
• a spring disposed between said blocking lever and said release button to rotate said blocking lever to lock-up said locking member in said latched position;
• and
• wherein said blocking lever comprises a main body portion and at least one detent portion extending from said main body portion for cooperating with said release button.
