Abstract

A seatback entertainment display system for a vehicle is provided having a support member extending from a seatback frame, and an adjustment mechanism coupled to the support member, and a display device coupled to the adjustment mechanism. The support member may be a cantilever type beam or frame extending upwardly from the seatback at a position behind and adjacent to a headrest. The support member may also be a pair of rods arranged to fixedly receive the display device and movably receive the headrest. The adjustment device may include any one or more of a forward-rearward tilting mechanism, a side to side pivoting mechanism and an up-down translation mechanism. The seatback entertainment display system is adaptable to optimize a viewing angle for a rear seat occupant of the vehicle, throughout a normal adjustment range of the seat.

Problems solved by technology

However, this known display device for seat backs has some disadvantages

For example, movement of the seat back (e.g., between a reclined position and an upright or forward-leaning position) can cause a user (e.g., a user sitting in the back seat of a vehicle) to view a display device from a non-optimal viewing angle s position

[0004] In addition, the height of this known display device installed in the seat back or headrest is usually determined by the height of the seat back or headrest, and if the seat occupant adjusts the height of the seat or headrest, then the height of the display will change

In addition, such known display devices have limited viewing angles and cannot be easily adjusted to accommodate the various heights and shapes of users viewing the display device (eg, adults, children, etc.)

By way of further illustration, such known seat back display devices are generally not adjustable laterally to improve the reclined position of the rear seat seated on the display device (e.g., a viewer seated in the "middle" position of the rear seat of a vehicle). viewer's perspective

While some known rear seat display devices mounted in the seat backs may provide some adjustment, these adjustments are usually of limited and unsatisfactory capability
