Abstract: The latch of a seat adjuster is pivotally mounted on a latch mounting bracket which, in turn, is secured rigidly to the upper track of the seat adjuster. The latch mounting bracket is formed with a weakened area in proximity to the pivot for the latch. In the event of a frontal crash, the weakened area deforms to enable the mounting bracket to move forwardly relative to the latch and clamp the latch in its latched position, thereby preventing the latch from pivoting to its unlatched position. A second bracket underlies the latch mounting bracket and coacts with the other latching elements to force the latching tooth of the latch to fail in shear rather than by bending. An anchor for a seat belt may be carried by the second bracket.
