DESCRIPTION:
BRIEF SUMMARY
This invention relates to collapsible seats and in particular, but not exclusively, to seats which can be placed on existing chairs to elevate a small child to table level. Such seats are sometimes called booster seats.
These days restaurants make a much greater attempt to accommodate young children, but frequently there are insufficient highchairs, particularly if a number of small children are in the same party.
From one aspect the invention consists in a booster seat comprising a collapsible structure moveable between a collapsible "flat" configuration and an erected position and including a wall and a seat engaged on a wall for relative movement thereto between a position in which it is supported on or adjacent the upper edge of the wall in the erected position and a position in which its front edge is generally aligned with the lower edge of the wall.
Preferably, the seat further includes a base and in this case the wall is a front wall which is pivotally mounted on the base for movement between the flat position in which it lies on the base and an erected upright position.
The booster seat may include an upper frame and a back wall pivotally mounted on a flat upper frame for movement between a flat position in which it lies on the frame and an erected, upright, position in which it engages the base. The back wall may define a ledge to support the rear edge of the seat in the erected position.
The seat may further include foldable side walls interconnecting the base and the upper frame for folding, as the structure is moved into its flat position, to lie between the base and the upper frame.
Straps may be provided for attaching the booster seat to an existing chair and preferably there are straps which pass both under the seat of the chair and around its back. Additionally or alternatively, the seat may include straps for retaining a child in the seat.
The components of the seat may be made from a light rigid plastic material such as polypropylene and one or more of the components may include a carrying handle aperture, which is accessible when the seat is in its collapsed position.
Although the invention has been defined above, it is to be understood that it includes any inventive combination of the features set out above or in the following description.
The invention may be performed in various ways and a specific embodiment will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a view from above of a booster seat;
FIG. 2 is a vertical central section through the booster seat of FIG. 1;
FIG. 3 is a view from the front of the right half of the booster seat;
FIG. 4 is a side view of the seat of the booster seat of FIG. 1;
FIG. 5 is a view from the front of the front wall of he booster seat;
FIG. 6 is a horizontal section through the front wall of FIG. 5;
FIG. 7 is a corresponding section to FIG. 2, but with the seat in its collapsed position;
FIG. 8 is a corresponding view to that of FIG. 3 in the collapsed position;
FIG. 9 is a view of the booster seat in its fully erected position;
FIG. 10 is a corresponding view with the seat partially lowered;
FIG. 11 shows the seat fully lowered and the back raised;
FIG. 12 shows the booster seat in a semi-collapsed position, and
FIG. 13 shows the booster seat in a fully collapsed position.
A booster seat generally indicated at 10, comprises a base 11, an upper U-shaped frame 12, a back wall 13, a front wall 14, a seat 15 and a pair of collapsible side walls 16.
The back wall 13 is pivotally mounted at 17 at the rear 18 of the upper frame 12 and frictionally locates at 19 on the base 11. The back wall 13 defines a ledge 20, which locates a flange 21 of the seat 15 to support it in the horizontal position shown in FIGS. 1 and 2. The front of the seat 15 is pivotally engaged on the front wall 14, in a manner which will be described below. The lower edge of the back wall 13 is pivotally mounted on the base 11 at 22.
Each side wall 16 comprises upper and lower portions 23, 24 which are hinged together by respective
