JAN.16.200; 15:5C +61 E 6311E300
MADDERNS-L
MADDENSL#3069 P-004 /007 2 c~KI FIELD OF THE INVENTION S 5 The present invention relates to a tether strap for a child safety seat.
BACKGROUJND OF TFlE INVENTION In current child safety seats, the child is restrained in the safety seat by a child harness, which O 10 is connected at the top and bottom to the shell of the safety seat. The seat shell itself is connected to 0 the vehicle by means of the vehicle seat belt, for example a lap/sash belt. In addition, it is usual to 00 have a tether strap connected to the shell and to a vehicle anchorage point. Typically, an upper tether O strap is connected to a vehicle anchorage point on a shelf behind the rear seat using a latching hook connector.
However, the shell of a child safety scat can have imperfections and weak points, which may give way in the event of a collision, thereby compromising the safety of the infant. Furthermore, children of different sizes are not always sufficiently restrained in the safety seat.
It is an object of the present invention to reduce or eliminate some or all of the disadvantages of conventional child safety seat arrangements.
SUMMARY OF THE INVENTION In a first aspect, the present invention accordingly provides a tether strap for a child safe-ty seat for connection to an anchorage point on a motor vehicle wherein a harness is used with the child safety seat to restrain a child in the child safety seat, the tether strap comprising: a strap having ends secured with respect to the child safety seat and secured with respect to the anchorage point at a point intermediate its ends, and a connection means carried by or with respect to the tether strap, the connection means extending away from the tether strap towards the child safety seat and having an aperture at an end spacoed from the tether strap for attachment of the harness.
Preferably, the connection means allows attachment of the harness used in the safety seat while also securing the tether strap to the same anchorage point. The upper end of the COMS ID No: ARCS-220229 Received by IP Australia: Time 16:36 Date 2009-01-16 00 3 O shoulder straps are able to be secured directly with respect to the anchorage point rather than ;to the shell of the safety seat.
Current arrangements rely on the mechanical integrity of the seat shell to secure the child with respect to the vehicle. In the event of a collision, the collision loads are applied to the seat shell. Therefore, the safety of the infant is dependent on the integrity of the seat shell.
However, this disadvantage is alleviated with the present invention, where the upper securement point of the harness is able to be secured independently of the seat shell and with
OO
0respect to the same anchorage point to which the tether strap is connected.
The harness includes two shoulder straps to extend over the child's shoulders, along their chest. These shoulder straps may be provided by looping a length of strap the safety seat and through a pair of apertures in the backrest portion. Further, the shoulder straps preferably each include a loop towards their bottom to receive a vehicle seat belt.
The harness is preferably adjustable to suit children of different sizes. The length of the harness may be adjusted, typically through an adjustable buckle, to tighten or loosen the harness. This buckle may be covered in use by padding. The harness may also, in some embodiments, be adjusted by passing it through higher or lower apertures in the seat shell.
The harness preferably also includes a cross strap connecting the two shoulder straps at a point below the child's shoulders. The cross strap may be strongly fixed to one shoulder strap for instance by stitching but preferably is removably attached to the other shoulder strap for instance by a loop through which the shoulder strap can be passed. This arrangement is of particular advantage where the shoulder straps are provided by looping a main harness strap behind the safety seat, through apertures therein, because it allows for simple connection of the shoulder straps after they have passed through the apertures (during either assembly or adjustment).
A crutch strap attached to the seat shell may be secured to either the child harness or the vehicle seat belt to keep the vehicle seat belt as low as possible.
The connecting means may comprise a strap that is adjustable in length or a separate extension strap can be used which itself is ideally adjustable in length by means of adjustable 00 0 4 Sbuckles. This allows adjustment of the distance between the harness and the point or points at which it is secured to the vehicle.
BRIEF DESCRIPTION OF THE DRAWINGS SAn illustrative embodiment of the present invention will be discussed with reference to the accompanying drawings wherein: 00 0FIGURE 1 is a view of a harness incorporating an extension means; 10 FIGURE 2 is a view a harness for use according to another embodiment of the (-i present invention; FIGURE 3 is a view of a child safety seat arrangement according to a preferred embodiment of the present invention, in operation; FIGURE 4 is a rear view of a child safety seat arrangement according to a preferred embodiment of the present invention; FIGURE 5 is a top rear view of a child safety seat arrangement according to a preferred embodiment of the present invention, attached to a vehicle anchorage point; and FIGURE 6 shows a detailed view of a mounting arrangement as used in various embodiments of the present invention.
DESCRIPTION OF PREFERRED EMBODIMENT Figure 1 shows a child harness 20 consisting of two shoulder straps 21 and a cross strap 22. The shoulder straps are provided with padding 23, and the lower end of each shoulder strap 21 is provided with a loop 24 to receive a vehicle seat belt. The child harness is adjustable in length by means of an adjustable buckle 25, which is covered during use within the padding 23 on one of the shoulder straps 21. There is also a latching hook connector 26 on the upper end of the child harness In Figure 2, the same harness is shown with an additional extension strap 27, which in this instance is adjustable by means of another adjustable buckle 28. The extension strap 27 has a connection buckle 35 that enables attachment to the latching hook connector 26. A second latching hook connector 29 is attached to the other end of the extension strap 27.
00 SFigure 3 shows a front view of child safety seat arrangement according to the present ;Z invention in operation. A child harness 20 is shown holding the child 31 in a seat shell 30, by Cc means of shoulder straps 21. The harness 20 is passed through a pair of apertures 32 in the backrest portion of the safety seat 30. The shoulder straps 2 1 then extend over the child's 5 shoulders and chest. The vehicle belt 33 comprising either the vehicle lap belt or a C€3 IDcombination of the lap and sash belt is passed through the loops 24 at the lower ends of shoulder straps 21. The vehicle belt 33 can then optionally be connected to the safety seat by means of crutch strap 34 (shown not connected in Figure which helps keep the vehicle 00 0belt 33 as low as possible.
In Figures 4 and 5, there can be seen the mounting arrangements for securing the harness 20 and the safety seat 30 with respect to the vehicle. A tether strap 40 is connected to the backrest portion of the safety seat 30 at connection points 41 and 42, and at the other to a vehicle anchorage point 50 through latching hook connector 43. The length of the tether strap 40 can be adjusted through the adjustable buckle 46, to allow the mounting arrangement to suit different vehicles.
As is also shown clearly in Figures 3 to 5, the safety seat 30 includes multiple pairs of apertures 32, 32a and 32b. The harness 20 can be looped through any of these pairs to adjust the height of the shoulder straps 21 with respect to the size of the child 3 1. It is preferable to have the shoulder straps located close to the child's shoulders, as this gives greater retention of the child 31 in the safety seat. Although multiple pairs of apertures are shown in this preferred embodiment, it would also be possible to have the harness passed through a single aperture in the head end of the backrest portion or around grooves in the perimeter of the backrest portion. For instance, the shoulder straps could be joined before they are passed through a single aperture.
The harness 20 is secured with respect to the vehicle to an anchorage point through latching hook connector 26, connection means which in this embodiment comprises a connection strap 44, an aperture in buckle 45 and latching hook connector 43. In this instance, it will be noted that latching hook connector 43 is common to both the mounting arrangement for the harness 20, and to the mounting arrangement for the safety seat 00 0 6 b1 However, the harness 20 is still secured to the vehicle through an arrangement that does not include the safety seat Of course, the mounting arrangements for securing the harness 20 and safety seat with respect to the vehicle can take other forms.
IND
tr- Figure 6 shows in more detail the mounting arrangement shown in Figures 4 and _A tether strap 40 is connected to a vehicle anchorage point 50 through latching hook 00 0connector 43. The harness 20 is secured with respect to the vehicle through latching hook connector 26, connection strap 44, buckle aperture 45 and latching hook connector 43. In this instance, it will be noted that latching hook connector 43 is common to both the mounting arrangement for the harness 20, and to the mounting arrangement for the seat shell Although a number of embodiments of the present invention have been described in the foregoing detailed description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the invention. Modifications and variations such as would be apparent to a skilled addressee are deemed within the scope of the present invention.
