Abstract: This invention relates to the field of olefin polymerization catalyst compositions, and methods for the polymerization and copolymerization of olefins, including polymerization methods using a catalyst composition. One aspect of this invention is the formation and use of a catalyst composition comprising a transition metal compound and an activator for olefin polymerization processes.

Abstract: A fold-down seat frame for a motor vehicle is provided. The seat includes a seat bottom disposed in a predominantly horizontal position and a seat back adapted for movement between a predominantly vertical seating position and a predominantly horizontal reclined position. The seat back and seat bottom share an adjacent edge that forms a vertex between the two. An auxiliary section is adapted for movement between a seated position and a reclined position. When in the seated position, the auxiliary section is located substantially below the seat bottom, and when in the reclined position, the auxiliary section is interposed between the seat back and seat bottom and aligned in substantially horizontal fashion therewith. A hinging assembly interconnects the seat back, and the seat bottom, and the auxiliary section and operates to controllably and concertedly move the seat back, the seat bottom, and auxiliary section between the seated and reclined positions.
