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 built-in at said rear side of said head pillow; and an adjustable mounting arrangement, which comprises: a length-adjustable sliding guider longitudinally supported within said interior cavity of said head pillow, and comprises two sliding shafts; two supporting arms downwardly and parallelly extended from said sliding guider respectively through said bottom side of said head pillow to define an engaging distance between said two supporting arms; an adjuster which comprises a manual tuner, and a control sleeve, having two side opening ends, engaged with said sliding shafts of said sliding guider 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 securely attached to said supporting arms in such a manner that when said inner ends of said two sliding shafts are coaxially slid within side opening ends of said control sleeve respectively in a synchronized manner, said supporting arms are correspondingly moved to control said engaging distance between said two supporting arms, so that said adjuster is adapted 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, wherein said manual tuner is coaxially mounted to said control sleeve, and has a manipulating portion extending out of said interior cavity of said head pillow through said bottom side thereof to drive said control sleeve to rotate; and a one-piece supporting frame upwardly extended from said sliding guider within said interior cavity of said head pillow to support said display screen at said rear side of said head pillow so as to substantially retain said display screen in position, wherein said supporting frame comprises a supporting panel supported within said interior cavity of said head pillow and a base housing extended from said supporting panel to pivotally couple with said sliding guider in such a manner that said head pillow is pivotally moved for adjusting a head-supporting angle of said head pillow with respect to said car seat when said supporting arms are slidably inserted into said retention slots of said car seat respectively, wherein said display screen is securely supported by said supporting panel within said one-piece supporting frame to said head pillow.
