Abstract: A retainer 30 for a seat belt strap assembly 81 that includes an anchor body 35 having a securement portion 45 and a seat belt engagement portion 79. The securement portion 45 is adapted for being releasably mountable upon a front side panel 92 of a vehicle passenger seat 90. The seat belt engagement portion 79 is adapted for releasable engagement with the seat belt assembly member 84. The securement portion 45 is alternatively substantially U-shaped or J-shaped with an interior leg 50 adapted for abutting engagement with an interior surface 94 of a front side panel 92 of a vehicle passenger seat 90 and an exterior leg 60 adapted for abutting engagement with an exterior surface 96 of the same front side panel 92 of the vehicle passenger seat 90. In the J-shaped configuration, however, the interior leg 50 is shorter than the exterior leg 60.
