Abstract

A vehicle seat and seat back adjustment mechanism are disclosed that provide for adjusting the angle of inclination of a seat back relative to a seat base and also permit easy entry to the area behind the seat by allowing the seat back to be released to move between an adjusted angle of inclination and a position in which the seat back is folded over the seat base. The adjustment mechanism includes at least one comfort tilt recliner mechanism and one easy entry recliner mechanism that are joined via a first interface and a second interface face each, respectively, located on the outer surfaces of the facing plates of the two mechanisms by a radial laser welding process, such that the mechanisms may be coaxially attached to the vehicle seat to permit the seat back to pivot about a single axis.
