Patent ID: 6896326

Claim:
A rest apparatus for infants with backrest and headrest cooperation mechanism, comprising: a backrest; a seat frame pivotally connected to an end of the backrest; a headrest pivotally connected to another end of the backrest; and a cooperation mechanism, the cooperation mechanism further comprising: a first rod connecting with the backrest and having a first end and a second end opposite to the first end; a second rod having a third end, a fourth end opposite to the third end, and a pivot section between the third end and the forth end, wherein the third end is directly pivotally connected with the second end of the first rod and the pivot section is pivotally connected to the backrest; and a third rod having a fifth end directly pivotally connected with the fourth end of the second rod, and a sixth end opposite to the fifth end directly pivotally connected with the headrest; whereby during the seat frame, the backrest, and the headrest being relatively rotated, if the first rod moves relative to the backrest, the first rod cooperates the second and the third rods, and moreover changes the relative angle between the headrest and the backrest; on the other hand, if the first rod does not move relative to the backrest, the relative angle between the headrest and the backrest will remain unchanged, whereby movement of the first rod is determined by the inclination of the backrest.
