The headrest bracket includes a pair of spaced housing parts connected by one or more cross members to define a central recess part. The cross members may be integral parts of the top and bottom walls of each housing part. When mounted to the upper cross bar of the seat frame, the cross member overlies the cross bar. The recess part allows the center springs or other support members to be connected to the upper cross bar through. The recess part may have an opening to allow the supports to be connected directly to the cross bar.
