Abstract

The invention relates to a headrest for motor vehicle seats, comprising an upholstery support (2), a support rod (3) displaceably arranged relative to the upholstery support (2), connecting the headrest (1) to a backrest of the motor vehicle seat and at least two bearing elements (4) arranged in the longitudinal axial direction of the support rod (3), spaced apart from one another on the upholstery support (2) and at least partially encompassing the support rod (3), for guiding the support rod (3), the bearing elements (4) being elastically pretensioned in the direction of the support rod (3). In order to provide a headrest which permits a rattle-free arrangement of the upholstery support on the support rod and which has easy adjustability, it is provided that the bearing elements (4) comprise guide webs (20) distributed over their inner periphery, protruding toward the support rod (3) and extending in the longitudinal axial direction of the support rod (3).
