Booster seat

Abstract

An adjustable booster-type seat having a base 10 for supporting the seat on a flat surface, a riser 12 mounted for height adjustment on the base, a body support 14 having a seat and back mounted for arcuate motion on the riser 12 for changing the angular position of the body support 14 and being adjustable in height by virtue of the adjustability of the riser on the base. A restraint bar 16 is detachably connected to the body support and in turn adjustably carries a tray 18 enabling the tray to be moved toward and away from the back and to be mounted at different angles with respect to the body support 14.

What is claimed is:  
     
         1 . A booster seat comprising, 
 a base and a riser mounted on the base,    a track carried by the riser and a body support mounted on the track enabling said body support to move between an upright and reclined position,    a restraint including a post mounted on the body support for retaining a child in the support,    and a tray adjustably mounted on the restraint for enabling the tray to be moved toward and away from the body support and for changing the angular relationship of the tray with the body support.    
     
     
         2 . A booster seat as defined in  claim 1  wherein the body support includes a seat and backrest.  
     
     
         3 . A booster seat as defined in  claim 2  wherein the body support is a unitized structure that moves as a unit on the riser.  
     
     
         4 . A booster seat as defined in  claim 2  wherein the backrest is collapsible for reducing the size of the booster for travel and storage.  
     
     
         5 . A booster seat as defined in  claim 1  wherein the riser may be raised and lowered on the base for raising and lowering the body support with respect to the base.  
     
     
         6 . A booster seat comprising, 
 a base assembly and a seat and back mounted on the base assembly,    an arcuate support on the base assembly enabling the seat and back to move as a unit between upright, intermediate, and fully reclined positions and to be raised and lowered with respect to the base,    and a tray carried by the seat movable toward and away from the back.    
     
     
         7 . A booster seat as defined in  claim 6  wherein the angular relationship between the tray and seat may be varied.  
     
     
         8 . A booster seat as defined in  claim 6  wherein the backrest is collapsible for reducing the size of the booster for travel and storage.  
     
     
         9 . A booster seat as defined in  claim 6  wherein the seat and back have a fixed angular relationship with one another.  
     
     
         10 . A booster seat comprising, 
 a base and a riser attached to the base,    an adjustment mechanism operatively connecting the riser to the base for raising and lowering the riser on the base,    an arcuate track carried by the riser,    and a body support movable back and forth on the track for changing the angular orientation of the body support between upright and reclining positions.    
     
     
         11 . A booster seat as described in  claim 10  wherein the body support has an arcuate surface mating with the track.  
     
     
         12 . A booster seat comprising, 
 a base and a support having a pair of arcuate tracks running fore and aft, one on each side of the base,    a seat and back assembly having a fixed angular relationship mounted on the tracks for fore and aft and tilting motion to selectively move the assembly between an upright, reclined and intermediate orientations,    an adjusting mechanism operatively connected to the base and support for raising and lowering the seat and back assembly with respect to the base,    a restraining member attached to the assembly,    a tray adjustably supported on the member for back and forth and tilting adjustment enabling the tray to be placed in a substantially horizontal orientation when the seat and backrest assembly is in both the upright and tilted positions,    said back having upper and lower portions enabling the upper portion to collapse down on the lower portion to reduce the volume of the booster seat for storage and travel.    
     
     
         13 . A booster seat as described in  claim 12  wherein the restraining member is detachable from the base.  
     
     
         14 . A booster seat comprising 
 a base and a support adjustably mounted on the base for varying the height of the support with respect to the base,    a seat and back assembly mounted for tilting motion on the support enabling the assembly to move between upright and reclined positions,    and a tray movably mounted on the assembly enabling the tray to be horizontally oriented independent of the position of the assembly.    
     
     
         15 . A booster seat comprising, 
 a base and a seat and backrest assembly movably supported by the base for tilting motion thereon between upright and reclined positions,    and a tray mounted on the seat and backrest assembly for movement to a horizontal orientation when the assembly is in a reclined position.    
     
     
         16 . A booster seat as defined in  claim 15  wherein a restraint attached to the seat and backrest assembly supports the tray.  
     
     
         17 . A booster seat as defined in  claim 16  wherein the tray is adjustably mounted on the restraint for changing the plane of the tray.  
     
     
         18 . A booster seat as defined in  claim 16  wherein the tray is movable toward and away from the backrest.  
     
     
         19 . A booster seat as defined in  claim 10  wherein a latching mechanism is operatively connected to the body support and riser for selectively locking the body support in the upright and reclining positions and in at least one intermediate position between the upright and reclining positions.
