High chair with a backrest having adjustable inclination

Abstract

A high chair for a child with a simple control mechanism for adjusting the inclination of the backrest, including a foldable frame work, a seat portion, a backrest, an adjusting mechanism movable along the backrest, and a connecting element pivitolly interconnected between the adjusting mechanism and the foldable frame work. The adjusting mechanism can be manipulated to move along the backrest and carries the connecting element to pivotally change to different inclination angles, so as to support the backrest at different inclination angles.

1 . A high chair with a backrest having adjustable inclination, comprising: 
 a foldable framework having a deployed position and a foldable position;    a backrest having a pair of adjusting channels and a guide slot, the pair of adjusting channels and the guide slot being parallel;    a seat portion having two sides pivotally connected to the foldable framework and a rear end pivotally connected with the backrest;    a connecting element having a pair of arms and a pivot portion, wherein the arms connect to the pivot portion at one end, and the arms are pivotally interconnect the foldable framework at the other end; and    an adjusting mechanism movable connected with the backrest, having a pivotal base which pivotally holds the pivot portion of the connecting element and carries the connecting element to provide adjustable inclination support for the backrest, and has the pivotal base having a pair of catching blocks for movably engaging with the bottom of the adjusting channels to releasably fix the inclination position of the connecting element    
   
   
       2 . The high chair with a backrest having adjustable inclination as claimed in  claim 1 , wherein the adjusting mechanism further includes a limiting piece and a manipulating member, the limiting piece being formed with a pair of salient posts which pass through the guide slot of the backrest, and the manipulating member being rotatably connected with the pivot base and formed with a prop-up portion and a pair of receiving troughs for slidably receiving the salient post.  
   
   
       3 . The high chair with a backrest having adjustable inclination as claimed in  claim 2 , wherein the adjusting mechanism further includes a resilient element telescopically accommodated within the receiving trough for biasing against the pair of salient posts, thereby providing a force to keep the pair of catching blocks engaged with the bottom of the adjusting channels, so as to fix the inclination support of the connecting element and the backrest.  
   
   
       4 . The high chair with a backrest having adjustable inclination as claimed in  claim 3 , wherein the resilient element is a compression spring.  
   
   
       5 . The high chair with a backrest having adjustable inclination as claimed in  claim 2 , wherein the catching block and the bottom of the adjusting channel are formed with detent-like portions, through which a user can push the backrest upwards to change the inclination angle of the backrest without pressing the manipulating member.  
   
   
       6 . The high chair with a backrest having adjustable inclination as claimed in  claim 1 , wherein the foldable framework has a front leg and a rear leg and a pivot element, the pivot element being pivotally connected with the front leg, the rear leg and the connecting element, so as to deploy the front leg and rear leg to support the seat portions or collapse the front leg and rear leg into a compact size for storing in a limited space.  
   
   
       7 . The high chair with a backrest having adjustable inclination as claimed in  claim 1 , wherein the connecting element is pivotally connected to the pivot element.  
   
   
       8 . The high chair with a backrest having adjustable inclination as claimed in  claim 1 , wherein the prop-up portion protrudes from the pivotal base for pressing against the backrest and causing the backrest to move when the manipulating member is pressed to turn.  
   
   
       9 . A high chair with a backrest having adjustable inclination, comprising: 
 a foldable frame work pivotally connected with a seat portion;    a backrest pivotally connected with the seat portion;    an adjusting mechanism movable along the backrest; and    a connected element interconnected between the adjusting mechanism and the foldable frame work, wherein the adjustable mechanism can be manipulated to move along the backrest and carries the connecting element to pivotally change to different inclination angles, so as to support the backrest at different inclination angles.    
   
   
       10 . The high chair with a backrest having adjustable inclination as claimed in  claim 9 , wherein the foldable framework has a front leg and a rear leg and a pivot element the pivot element being pivotally connected with the front leg, the rear leg and the connecting element, so as to deploy the front leg and rear leg to support the seat portion or collapse the front leg and rear leg into a compact size for storing in a limited space.  
   
   
       11 . The high chair with a backrest having adjustable inclination as claimed in  claim 9 , wherein the connecting element is pivotally connected to the pivot element.
