Definitions

  • Foldable child safety seat suitable for restraining a child in a vehicle
  • This invention concerns a child safety seat for restraining a child in a vehicle.
  • the invention's design is unique because it is possible to fold up the child seat into a very compact shape so that it takes up a minimum of space in the boot of a car, for instance, after the child safety seat has been folded up.
  • Most of the currently available child safety seats are typically designed as a child safety seat with a back rest, where in most cases the chair bottom and back rest are permanently attached to one another.
  • the familiar chair designs usually involve constructions where both the chair bottom and back rest are made of the same material and often made in the same moulding process.
  • There are other familiar child safety seats where it is possible to fold down the back rest against the seat bottom for the very purpose of making the child safety seat as compact as possible.
  • One aim of the present invention is to make a child safety seat with special backrest fittings that are designed so the back rest can pivot on a central shaft in the back rest, after which both the chair bottom and back rest can be folded into an even more compact shape than ordinary child safety seats.
  • the first example of this shown in the periodical "WO 2005/01233, was a child safety seat whose chair bottom and back rest (6) are hinged
  • a fourth example from US patent document no. 5 785 383, describes an infant safety seat with chair bottoms which restrain infants placed in a vehicle.
  • the infant safety seat is made up of an upper back rest which pivots around a horizontal shaft via a hinge.
  • Child safety seats of the above-mentioned type have a number of undesirable aspects.
  • these child safety seats cannot be folded or rotated into very compact shapes, because the well-known child seats are equipped with side protrusions in both the back rest and chair bottom to keep the child from sliding sideways out of the child safety seat.
  • these protrusions prevent the back rest and chair bottom from being folded into a very compact shape, because when the protrusions come in contact with one another, they prevent further folding of the two sections.
  • a second aspect of ordinary child safety seats is that they are shaped so the chair-bottom surface is concave for ergonomic reasons, which is also true of the back rest that is also concave.
  • these concave shapes of the back rest and chair bottom create a geometric cavity between chair bottom and back rest.
  • these two oppositely facing concave surfaces of the chair bottom and back rest will create an air space whose sole purpose is to ensure that child safety seats are comfortable and ergonomic.
  • the present invention produces a child safety seat with a back rest and chair bottom which are interconnected by fittings that make it possible to fold up the back rest and chair bottom to become much more compact than ordinary child safety seats.
  • Ordinary child safety seats are made both with concave surfaces for chair bottom and back rest and with side protrusions.
  • Another advantage of the present invention is that the child safety seat is movably joined using a special flexible fitting connecting the chair bottom to the back rest, so that the back rest and chair bottom can be moved differently in relation to one another, which includes linear, rotating and pivoting movements.
  • the flexible fitting is designed so that it can be properly locked to keep the child safety seat in the position preferred, and the fitting is capable of withstanding forces which arise when a vehicle is involved in a collision.
  • a third advantage is that it is simple to operate the flexible fitting using a handle connected to the fitting's release mechanism. This handle is also located on the exterior rear surface of the back rest, so it is not possible to unintentionally unlock the child safety seat once it has been placed in the vehicle.
  • a fourth advantage is that when the child safety seat is folded up, it is possible to sit on top of the child safety seat making it possible for older children to use the child safety seat, and also making it easier for them to look out of vehicle windows. Moreover, when folded up, the child safety seat is very compact and, stowing the child safety seat takes up very little space in the vehicle's boot when the child safety seat is not in use.
  • the back rest is made with one or more grip hooks which mesh with a horizontal shaft positioned on the hindmost edge of the chair bottom.
  • the invention specified is based on the design of back and seat as shells, that can be manufactured by injection moulding or plastic blow moulding, making it possible to manufacture the child.safety seat in a manner that keeps costs very modest compared to ordinary child safety seats.
  • Figure 1 shows a child safety seat in the first constructional embodiment where the back rest is made with grip hooks and the chair bottom is made with a horizontal shaft on the hindmost edge of the seat.
  • Figure 2 shows a front view of the child safety seat shown in Figure 1.
  • Figure 3 shows a top view of the child safety seat and back rest shown in Figure 1.
  • Figures 4 and 4A show the child safety seat shown in Figure 1 , with the chair bottom and back rest meshed with one another via grip hooks and the horizontal shaft in the chair bottom.
  • Figures 5 and 5A show how the back rest and chair bottom, according to Figure 1 , are stacked to achieve a very compact shape.
  • Figure 6 shows a perspective view of the child safety seat in a second constructional embodiment where the back rest and chair bottom are joined using a very flexible fitting.
  • Figure 7 shows a perspective view where the back rest is axially shifted using the special flexible fitting.
  • Figure 8 shows a close-up view of the special flexible fitting shown in 175 Figure 7.
  • Figure 9 shows how the special flexible fitting can be pivoted around a central shaft lengthwise in the back rest.
  • Figure 10 shows the special flexible fitting when child safety seat is in an assembled configuration.
  • Figure 11 shows the special flexible fitting where the back rest is axially 185 shifted.
  • Figure 1A shows a sliding catch with a central slit.
  • Figure 12 shows how the back rest and chair bottom seat become very compact using the special flexible fitting.
  • the invention's first constructional embodiment includes a back rest (102) and a chair bottom (101 ) made of a polymer material where the chair bottom and back rest are constructed as a shell, which can be
  • the back rest is made with one or more grip hooks (105) in the lower section of the back rest.
  • the back rest and chair bottom are also made with side protrusions (102) to keep the child from sliding sideways out of the child safety seat in transit.
  • the chair bottom (101) is made with a horizontal shaft (103) placed in the hindmost edge of the chair bottom between two protruding flanges (104).
  • the child safety seat When the child safety seat is to be made ready for use, the child safety seat is assembled by placing both the back rest and chair bottom in a horizontal position (see Figure 1 ), and inserting the grip hooks (105) on the back rest so they mesh with the horizontal shaft (103), after which the back rest is rotated to a vertical position, as shown in Figures 4 and 4A. This creates a pivotal coupling between grip hooks and horizontal shaft, which is attached/retained around the horizontal shaft.
  • the grip hooks ( 05) and the horizontal shaft (103) be made of a solid polymer material but these components can also be made in other materials, such as metals or composites.
  • the back rest and chair bottom are disassembled by placing them in a vertical position in relation to one another. This makes it possible to release the pivotal coupling between the grip hooks (105) and the horizontal shaft (103), as shown in Figure 1.
  • the invention also includes a second constructional embodiment where the back rest and chair bottom are permanently attached by means of a special flexible fitting (1 ).
  • Figure 6 shows the child safety seat assembled using the flexible fitting.
  • the upper section of the flexible fitting (3) is attached to the rear surface of the back rest (2), while the lower section (4) of the fitting is attached to the hindmost end of the chair bottom.
  • Figure 7 shows how the upper and lower sections of the fitting are placed on back rest and chair bottom respectively.
  • Figures 10 and 11 show a sectionalised view showing how the
  • the upper section of the fitting consists of a rectangular profile (5) with a notch (6).
  • a handle (7) is positioned on the interior of the rectangular profile and can be moved up and down in the interior cavity 250 delimited by the profile.
  • a connecting bar (9) is attached to one end of the handle's lower curled edge (8), and the other end of the bar is attached to a latch mechanism (10) as shown in Figures 0 and 11.
  • the latch mechanism is composed of a housing (11 ), and inside the 255 housing is a bottom hole joint (12) containing a sliding catch (13) and a spring (14), placed between the bottom hole and the interior end of the sliding catch.
  • the exterior end of the catch (15) is smaller and the exterior end of the catch is made with an angled cut-off, as shown in the figure.
  • the catch has a central slit (16, see Figure 1 A), which extends a little more than halfway along the length of the catch, and an angular joint (17) is placed in this slit, which is pivotally attached to the housing (11 ) around a horizontal shaft (18).
  • the angular joint is connected to the lower end of the bar joint, whereas the angular joint's other end (17a) meshes with the 265 catch's central slit (16).
  • the other end of the angular joint (17a) will push the catch into the hole (12), thereby compressing the spring (14), and disengaging the catch's external end (15) from the hole joint (30), placed in the lower section of the fitting (4), and making it
  • Figure 11 shows the child safety seat with one latch mechanism, but the child safety seat can easily be made with two latch mechanisms that will typically be positioned at either 275 side of the back rest.
  • the flexible fitting also comprises a hinge for rotating and bending movements (19, see Figure 11 ), which physically joins the chair bottom to and the back rest with 280 upper and lower hinge sections respectively.
  • the upper hinge section is secured to the back rest via a bracket joint (20), which is attached to the back rest using a screw joint (21 ), for instance.
  • a round shaft joint (22) is placed inside the bracket joint, which ends at one end in a stop flange joint (23), the dimensions of which are bigger than the shaft, and a spiral spring joint (24) is positioned between the stop flange joint and the bracket.
  • One end of the shaft joint (22) is attached to a horizontal shaft (25) which is pivotally connected around a horizontal shaft (26).
  • the lower hinge section is secured to the seat via a pronged bracket (27, 28 and 29, see Figure 1 ), composed of a pronged fitting (27), and two shaft joints (28) and an end flange (29).
  • the shaft joint (28) is led through the chair bottom's shell, and the end flange (29) is attached inside the chair bottom by placing a plate spring (30) between the end flange and the chair bottom's inside shell.

  • the interior section of the back rest is bent down across the chair bottom, via the horizontal shaft (25), which is pivotally joined around a horizontal shaft (26).
  • the child safety seat is now folded up to its full extent and has a very compact shape which takes up a minimal amount of space and can still be used by older children.
