BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a booster seat, which makes it possible for children to use the ordinary automobile seat belts intended for adult passengers.
Booster seats have been in use for several years, to adapt the webbing of the automobile seat belt to a child passenger. Those booster seats have included booster cushions provided with straps and guides or adjustable loops for adaptation of the webbing to the child user.
The earlier booster seats have all been formed to make one adaptation of the webbing irrespective of the size of the child, although the adaptation can differ between different booster seats. Due to the fact that these booster seats are used by children from about 3 years age to about 12 years age, the size of the child user differs substantially during these years, and consequently the adaptation of the webbing is not the best during the whole span of normal expected use.
SUMMARY OF THE INVENTION
The object of this invention is to provide a booster seat by means of which it is possible to adjust the adaptation of the webbing depending on the size of the child user.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described in form of nonlimiting embodiment, shown in the appended drawings.
In the Drawings, FIG. 1 are shown two views of a booster seat according to the invention, to the left showing the seat adapted for a larger child than the seat shown to the right, and in FIG. 2 is shown an exploded view of the booster seat according to the invention.
DETAILED DESCRIPTION
The booster seat shown includes a booster cushion 1 with a double sided seating plane 2 and side portions 3. The side portions 3 also include safety belt guides 4. The booster cushion 1 is so formed that it can be turned upside-down, and be used in both the one-side-up orientation shown at the left in FIG. 1, and in the other-side-up orientation shown at the right in FIG. 1. The seating plane 2 is not located on the middle of the height of the side portions 3, but displaced towards one of the horizontal ends 12, 13 of the side portions 3, namely the end 12. By this arrangement, the generally horizontal support surfaces 14, 15 provided on opposite faces of the seating plane member 2 provide different seat levels, which can be obtained by locating the booster cushion 1 in one or the other location of its mutually inverted orientations. The safety belt guides 4 are formed with guide means 20, 21 on both lateral sides of the booster cushion 1 and also above and below, respectively both upper and lower surfaces 14, 15 of the cushion to be able to act as guides for the ordinary safety belt of an automobile in both orientations of the booster cushion 1.
As shown in the drawings the booster seat can also include a back rest 5. The back rest 5 is provided with a head rest 6, the lower side part 16 of which is formed to also act as a guide means for the shoulder belt of the ordinary automobile three point safety belt. The back rest 5 can also, as shown in the drawings, be provided with detachable and adjustable side supports 7, to give side support to a child sitting on the seat.
To make it possible to turn the booster cushion 1 upside down, the back rest 5 is connected to the booster cushion 1 by means of grip screw means 8 penetrating side beams 17 of the back rest and secured in threaded sockets 9 in the back part of the booster cushion 1. The sockets 9 are so located in the booster cushion 1 that they are at the bottom of the booster cushion when this is turned so that the seating plane 2 is in its most elevated position (shown at the right in FIG. 1), and thus so that they are located at the top of the booster cushion when the booster cushion is inverted, as indicated by the turnover arrow 18, so that the seating plane is at its lowermost position (shown at the left in FIG. 1). By this arrangement, the height of the back rest 5 is adapted to the intended use for different sizes of the occupants. Thus, with a smaller and shorter child, the booster cushion 1 should be turned so t
