Patent ID: 7637568

Claim:
A car seat with an extendable back for use in a car which comprises: a seat member having a bottom for positioning upon a seating surface within said car; a back member connected to said seat member, said back member further comprising: a fixed component having a laterally extending essentially flat middle section and a pair of raised contoured sides adjacent said middle section; a movable component having a laterally extending essentially flat middle section and a pair of raised contoured sides adjacent said middle section capable of movement from a retracted position to at least one extended position, said movable component comprising: an upper headrest area with a pair of forward extending wings and an upper headrest interior width as measured between said forward extending wings, a lower area separated from said upper headrest area by a pair of fixed size laterally and inwardly-projecting indentations, said indentations extending into said middle section of said movable component and accommodating an automobile shoulder belt through one of said indentations, said lower area having an inner surface and a pair of raised sides and a contour in cross-section for sliding movement along said fixed component having a mating contoured surface in cross-section, said lower area fixedly connected to said upper headrest area, said lower area having a lower area interior width as measured between said raised sides, said movement from said retracted position to said at least one extended position occurring by sliding movement of said movable component over said fixed component along said raised contoured sides of both said fixed and movable components; said upper headrest area in invariant fixed relationship to said lower area and separated by said indentations, said fixed and movable components in overlapping essentially gapless relationship with respect to each other with sliding movement between said components at both said retracted and extended positions, and further wherein sliding movement between said components does not increase a size of said indentations between said upper headrest area and said lower area; and a means for selectively positioning and retaining said movable component relative to said fixed component; wherein said inner surface of said lower area is positioned in front of said fixed component to form a contiguous upper seat back area; wherein said essentially flat middle section of the fixed component forms a lower seat back area; and wherein said fixed component and said movable component permit telescoping movement therebetween.
