A stabilized herbicidal composition comprising fenoxaprop ester herbicide in combination with pyrasulfotole. The assembly includes a housing for a seat belt anchor adapted for movement relative to the housing into an overload position where a portion of the anchor is abutted against a portion of the housing to limit and arrest the movement of the anchor relative to the housing and transfer the load from the anchor to the housing and then to an interior structure of the vehicle. The first controller feedback-controls the first stage according to a respective parameter vector. A first torsion member may be coupled to the vertical support member at the first longitudinal end, and a second torsion member may be coupled to the vertical support member at the second longitudinal end. The nail plate may contain protrusions that have a hook feature to prevent the nail plate from pulling out of the boards.
