Title: High chair for children convertible into a booster seat

Description:
TECHNICAL FIELD 
     The present invention relates to a high chair for children convertible into a booster seat comprising an upper part and a base, the upper part having a seating surface adapted for engagement with the base, lateral armrest sides, a backrest whose perimeter boundary extends from one lateral side to the other, as well as a backrest extension extending in cantilever fashion from the perimeter boundary of the backrest. 
     BACKGROUND OF THE INVENTION 
     In the prior art, in compliance with safety standards, high chairs for children have the upper part secured to the base by means of coupling members which allow it to be removed and placed on a normal adult chair to act as a booster seat. 
     Such arrangement allows, for instance, children to sit at the same table as adults, and is particularly useful when a child is too small to use a normal adult chair but has grown enough to find the high chair too narrow and uncomfortable, or when the use of the high chair is not practical (for example for size restrictions) 
     In the prior art, in compliance with safety standards, the upper part of high chairs, which is designed to receive very small children, has a backrest that encircles the shoulders of the child when he/she sits on the seating surface. 
     When the upper part of a high chair is removed from the base to act as a booster seat, the encircling configuration of the backrest causes the booster seat to have a large size, and be difficultly transported and used in non-domestic environments. 
     Furthermore, if the booster seat is used by a child that has grown enough to stop using the high chair, the backrest of the booster seat, due to its large size, will make the use of the booster seat quite inconvenient. 
     The object of the present invention is to obviate the drawbacks associated with the use of the upper part of a high chair as a booster seat. 
     Particularly, one object of the present invention is to provide a high chair for children convertible into a booster seat, in which the booster seat can be easily transported. Another object of the present invention is to provide a high chair for children convertible into a booster seat that can be also used by children that no longer need a high chair. 
     SUMMARY OF THE INVENTION 
     These and other objects, as better explained hereafter, are fulfilled by a high chair whose upper part, removable from the base, is as defined in one or more of the accompanying claims.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the accompanying figures, and particularly to  FIG. 1 , the high chair of the invention comprises an upper part, generally referenced  1 , and a base, generally referenced  2 . 
     In the illustrated embodiment the base comprises two structures, i.e. a front structure and a rear structure, referenced  3  and  4 . Each of the front and rear structures  3 ,  4  is composed of tubular elements that are bent into a C configuration. 
     These structures  3 ,  4  are hinged along a horizontal connection axis X-X about which they can be opened and folded in tripod fashion. 
     The base has mechanical connection members, e.g. a surface  5  designed to have the upper part  1  removably connected thereto to form a child seat. In the preferred embodiment of the invention, the upper part  1  has a seating surface  6  adapted to be coupled to the surface  5  of the base. 
     The seating surface  6  has lateral sides  7  and  8  and a backrest  9  connected thereto. 
     The latter has a perimeter boundary comprises a top section  10  and two lateral sections  11 ,  12  each facing its respective lateral side  7 ,  8 . 
     The backrest  9  also has a backrest extension  13 , which extends in cantilever fashion from the perimeter boundary of the backrest  9  itself. 
     Such backrest extension  13  consists of a body separate from the backrest  9  of said upper part of the high chair and comprises members for removable connection to the perimeter boundary of the backrest  9 , as better explained hereinbelow. 
     This extension  13  of the backrest  9  comprises lateral portions  14  and  15  which extend along said lateral sections  11 ,  12  of the backrest  9  that face the lateral sides  7 ,  8 . The members for removable connection of said backrest extension  13  to the backrest  9  comprise interlocking members consisting, in the preferred exemplary embodiment, of a groove  16  formed in the top section  10  of the boundary of the backrest  9  and a corresponding tongue  17  on the extension  13 . The tongue  17  is placed on an operating member, preferably a flat wing  18  which projects in cantilever fashion from the rear side  13   a  of the backrest extension  13 . The flat wing  18  is elastically connected to the backrest extension, to allow disengagement of the tongue  17  from the groove  16 . 
     The members for removable connection of said backrest extension  13  to the backrest  9  further comprise hook-like elements  19 ,  20  preferably located at the ends  21 ,  22  of the lateral portions  14 ,  15 . 
     Said hook-like elements  19  and  20  are adapted for removable engagement into corresponding slots  23 ,  24  formed on said lateral sections  11 ,  12  of the boundary of the backrest  9  facing said lateral sides  7 ,  8 . 
     It will be appreciated from the above discussion that the backrest extension  13  may be easily removed from the backrest  9  by acting on the handgrip  18  to lift the tongue  17  and remove it from the groove  16  formed in the backrest  9 . The extension  13  is fully separated by displacing the extension  13  toward the front side of the backrest  9  with a rotation of the hooks  19  and  20  within their respective slots  23  and  24 . 
     Once the upper portion of the high chair is released from the extension  13 , it may be used as a booster seat for a sufficiently grown-up child that might find such extension  13  inconvenient. 
     Nevertheless, for very small children, the extension  13  may be left connected to the backrest  9  and the upper part  1  of the high chair  1  may be still employed as a booster seat. For this purpose, the upper part  1  of the high chair comprises, as it is known in the art, belts  25  for retaining the child on the seating surface  6 , as well as belts, not shown, for removable fixation of an adult chair to the backrest and the seating surface respectively, when said upper part  1  acts as a booster seat. 
     The high chair of the present invention has been only described with reference to its construction and operation features. 
     The high chair also comprises a textile cover for the backrest and the backrest extension, not shown. The portion of the textile cover for the backrest extension  13  can be physically separated from the portion of the textile cover for the backrest  9 . 
     Particularly the portion of the textile cover of the backrest extension has a shape that is substantially equal to the shape of the backrest extension. This textile portion is joined to the textile portion of the backrest  9  using connection means such as Velcro or zippers. Thus, once the portion of the textile cover for the backrest  9  has been released from that for the backrest extension  13 , the latter can be removed.
