<p>Seatbelt buckle assembly 307 comprises a cover (350, Fig. 4 ) or bristles 370 arranged to keep foreign objects out of the buckle interior; particularly where a latch (not shown) engages with and retains the seatbelt tongue (200, Fig. 1 ). The flap or bristles may rotate outwardly ( Fig. 9 ) to expel foreign objects; and may be actuated by a press button (360, Fig. 4 ) or press panel 380 in the buckle assembly. The flap may be opened automatically by a sensor (420, Fig. 7 ) signal as webbing is paid out from a retractor reel (400, Fig. 7 ). The flap or bristles is/are mounted adjacent to an outer tongue insertion area (320, Fig. 3 ), which is adjacent to a tongue release button 310. Advantage: prior art buckles allow foreign objects to fall into a tapered passage (330, Fig. 3 ) leading to an inner tongue insertion area (340, Fig. 3 ).</p> |
