Claim:
A car seat head rest for mounting on a car seat having two spaced apart retention slots, comprising: a head pillow having a rear side, a bottom side and an interior cavity; a display screen supported at said rear side of said head pillow; and an adjustable mounting arrangement, which comprises: a length-adjustable sliding guider which is longitudinally supported within said interior cavity of said head pillow, and comprises a control sleeve; a supporting frame, which is coupled with said sliding guider, comprising two overlapped sliding panels being overlapped with each other and supported in said interior cavity of said head pillow in a slidably movable manner and two supporting arms downwardly and parallelly extended from two outer edges of said sliding panels respectively through said bottom side of said head pillow to define an engaging distance between said two supporting arms, wherein said control sleeve has two side opening ends and two sliding shafts slidably engaging with said control sleeve at a position that inner ends of said sliding shafts are coaxially and slidably engaging with said side opening ends of said control sleeve respectively while outer ends of said sliding shafts are coupled with said supporting arms respectively, wherein when said inner ends of said two sliding shafts are coaxially slid within said side opening ends of said control sleeve respectively, said sliding panels are slid with each other to move said supporting arms correspondingly in order to control said engaging distance between said two supporting arms, wherein said sliding panels not only rigidly support said head pillow but also provide a stable sliding movement of each of said supporting arms in a synchronized manner; and an adjuster provided at said sliding guider to control a length of said sliding guider so as to selectively adjust said engaging distance of said supporting arms, wherein when said engaging distance of said supporting arms is adjusted corresponding to a distance between said two retention slots of said car seat, said two supporting arms are adapted for slidably engaging with said two retention slots respectively so as to securely support said head pillow on said car seat.
