Child restraint seat including automatic pivot hinge

A child restraint seat for disposition in the backrest cushion of an adult passenger seat for restraining a child in a vehicle comprising:

• an adult passenger seat having a generally horizontal seat portion and a generally upright backrest portion, said backrest portion including a front face for supporting a passenger's back;
• a cavity recessed in said front face of said adult backrest portion for receiving said child restraint seat;
• a child seat portion having a first end pivotally coupled to said adult passenger seat and pivotal between a folded position recessed in said cavity forming at least a portion of said face of said adult backrest portion and an unfolded use position extending downwardly to a generally horizontal position against said adult seat portion;
• a child backrest portion disposed in said cavity and pivotally connected to said adult backrest portion for providing pivotal rotation of said child backrest between a first position generally parallel with said adult backrest and a second inclined position tilted outwardly to a predetermined child backrest angle, said child backrest portion including an upper end and a lower end;
• hinge means interconnecting said first end of said child seat portion and said lower end of said child backrest portion for automatically pivoting said child backrest portion from said first position to said second inclined position in response to pivotal rotation of said child seat portion from said folded position recessed in said cavity to said unfolded use position against said adult seat portion thus enabling a child to be positioned on the seat in an optimum inclined seating position;
• pivot means spaced below said upper end of said child backrest portion for pivotally coupling said child backrest portion and said adult backrest portion and for extending said lower end of said child backrest outwardly away from said adult backrest while retracting said upper end of said child backrest into said cavity and towards said adult backrest upon said automatic pivotal movement of said child backrest from said first position to said inclined position.
