A vehicle seat frame (10) includes a first upper back frame member 24 having at least one tab 26 suitable for supporting a dynamic head restraint system. The first upper back frame member 24 has upper and lower mating surfaces 28 and 30 suitable for attachment to upper and lower mating surfaces 38 and 40 of a second upper back frame member 32 operable to support a non-dynamic head restraint system (15a). A third upper back frame member 46 can be used instead of the second upper back frame member which is operable to support and/or permit operation of a dynamic head restraint. The tab can have an aperture (27) in it. Different head rest frames can be configured by utilizing a common first upper back frame member and a second or third upper back frame member for mounting non-dynamic or dynamic head rests. The upper back frame members can be formed from a stamped sheet and the mating surfaces can be secured to one another by spot welding. |
