A variable-height and variable-slant head rest with a center window, for motor vehicles comprising two mounting rods adapted to be attached by their one ends to the back rest of a motor vehicle seat and a support frame embedded in a cushion body and adapted to be shifted along the mounting rods and to be pivoted in relation to the mounting rods and having hollow side struts receiving the other ends of the mounting rods. The support frame is pivotally supported on two circular disks running on the one ends of the mounting rods. The disks are each arranged in a cylindrical socket of corresponding diameter formed by a widened portion of a slot-like cavity on both side struts of the support frame. Each cavity has a width substantially equal to the diameter of its respective mounting rod and abutment surfaces for the mounting rod which diverge in a direction away from the socket. The disks each have a diametral hole through which the respective mounting rod extends. |
