This invention relates to a tamper guard for a child restraint system. In particular, the invention is concerned with the child tamper proofing of a restraint system found on a child safety seat.
BACKGROUND ARTThe following discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.
Child safety seats are used by parents worldwide to protect their children from injury or death during adverse vehicular incidents. These child safety seats are also generally a legal requirement in many countries for the transportation of children in vehicles, such as automobiles and aircraft.
The primary components of the child safety seat are a seating portion for the comfortable transportation of a child, and a restraint system to ensure that the child is safely secured to the seating portion during transportation and in adverse vehicular incidents. The type of the seating portion is dependent upon the age and size of the child; however, the types are typically either a carrycot or a bucket seat. The restraint system is generally a five-point harness, in which five straps anchored to the seating portion meet at and connect to a centralised buckle. The combination of the five straps and the centralised buckle provide a secure means of safely retaining the child's body within the seating portion, thereby protecting the child from incurring serious injury during adverse vehicular incidents.
To allow for the release of the straps, the centralised buckle is typically equipped with a quick release mechanism. The quick release mechanism is typically a large visible push button located on the centralised buckle, which when depressed releases the retained straps allowing the child to exit the seating portion. However, inquisitive children are likely to tamper with the quick release mechanism, which may lead to a pre-mature exit from the child safety seat. This unintended and unsupervised exit may endanger the child's life during transportation in a moving vehicle.
A typical solution for minimising the child's opportunity to successfully operate the quick release mechanism is the use of components requiring a specific amount of force, greater than what a typical child below the age of 4 can muster, to actuate. However, inquisitive children may be able to determine methods of bypassing this solution, such as hitting the button with a heavy solid object or leveraging the combined force of both hands to depress the button. In addition, the use of such solutions may impede removal of the child from the safety seat during emergencies.
Another solution involves the installation of a third-party item, such as a cover for the quick release mechanism. The cover typically encases most of the quick release mechanism, so that the child is unable to visually identify the button and is physically denied access to the button. An example of the cover is the Merritt™ Buckle Guard. This buckle guard consists of a plastic cover that encapsulates most of the buckle release mechanism to obscure it from visual identification and acts as a hard barrier to operation. However, the use of the cover provides the dangerous disadvantage of obscuring the quick release mechanism. By obscuring the quick release mechanism, in the event of an adverse vehicle incident, emergency responders are required to spend time to determine how to actuate the quick release mechanism with the obscuring cover. This may mean the difference between life and death in a critical situation. Additionally, the cover may be damaged during adverse vehicular incidents, leading to the requirement of tools to remove or bypass the cover by emergency responders. For these reasons, the use of a cover for the quick release mechanism is often prohibited in many countries.
The current invention was conceived with these shortcomings in mind.

The description will be made with reference to the accompanying drawings in which:
Further features of the present invention are more fully described in the following description of several non-limiting embodiments thereof. This description is included solely for the purposes of exemplifying the present invention to the skilled addressee. It should not be understood as a restriction on the broad summary, disclosure or description of the invention as set out above. In the figures, incorporated to illustrate features of the example embodiment or embodiments, like reference numerals are used to identify like parts throughout.
With reference to the accompanying drawings, there is shown a tamper guard 10 for a child safety seat. In general, the tamper guard 10 generally comprises a hollow tubular upper portion 12 and a lower portion 14 configured to operatively secure the upper portion 12 to a buckle of the child safety seat. The upper portion 12 and the lower portion 14 generally cooperate to form a continuous opening 18 from a distal opening 16 of the tubular upper portion 12, with the continuous opening 18 configured to display and allow access to a quick release mechanism 34 located at a front face of the buckle 32 for an adult 54 whilst impeding access to the quick release mechanism for a child 56 seated in the child safety seat.
In the embodiment exemplified in the accompanying drawings, the tamper guard 10 comprises an upper portion 12 and a lower portion 14. The upper portion 12 is configured as a hollow prism or cylinder having a top distal opening. The lower portion 14 is a body comprising a quadrilateral top face having an opening of similar cross-section to a bottom opening of the upper portion 12. The lower portion 14 further comprises an integral retainer located below the quadrilateral top face. The upper portion 12 and the lower portion 14 are connected to and cooperate with each other to receive and retain a buckle within a space defined by the quadrilateral top face and the retainer. The retainer subsequently retains the buckle within the space. Additionally, the upper portion 12 and the lower portion 14 cooperate to form a continuous opening from the distal opening of the hollow prism or cylinder to the opening of the top face. The continuous opening is configured to display and allow access to a quick release mechanism located at a front face of the buckle.
It would be appreciated by those skilled in the art, that the continuous opening is preferably configured to fully display the quick release mechanism of the buckle to allow for the rapid recognition and actuation of the quick release mechanism by an adult, particularly in the event of an adverse vehicular incident such as by first responders or emergency responders. Additionally, the upper portion 12 is preferably configured to be of a height that disallows a finger or fingers of a child to reach and/or actuate the quick release mechanism of the buckle.
It would be appreciated by those skilled in the art that the retainer may be of another form that is suitable for securely retaining the buckle 32. In another preferred embodiment, the retainer is configured as a pair of opposing members extending from edges of the square top face 20 and connecting to edges of a bottom face of similar dimensions to the square top face 20. The bottom face is further configured to have a substantially rectangular opening to display a back face of the buckle, which typically contains safety information relating to the child safety seat. In this arrangement, the buckle 32 is received in the space defined by the inner wall of the square front face 20, the inner walls of the pair of opposing members, and the inner wall of the bottom face by sliding the buckle 32 through the openings not covered by the pair of opposing members. In a further embodiment, the retainer is configured as a pair of opposing members extending from edges of the square top face 20 which connected with a pair of longitudinally extending rods using snap fasteners.
To allow for the elastic deformation of the pair of opposing members 22, 24 the upper portion 14 is generally manufactured from a resiliently flexible material. However, to ensure that a child is physical unable to deform the material using their hands, the resiliently flexible material must have an elastic modulus value that may be overcome by the strength of an adult but not that of a child. Similarly, the lower portion 12 is also typically manufactured from a resiliently flexible material.
It is further demonstrated in
Additionally, the continuous opening 18 provides access for a finger of an adult's hand 54 to actuate the push button 34. To ensure that the continuous opening 18 is of a sufficient height that a finger of a child's hand 56 is unable to reach and/or properly actuate the push button 34, the height of the upper portion 12 must be of a height that is greater than that of the length of the finger of a child's hand 56. The average length of a 4-year-old child is approximately 60 mm. As such, the height of the upper portion 12 may be greater than 60 mm, but the skilled addressee will appreciate that variations are possible and within the scope of the present invention.
It would be appreciated by those skilled in the art that the upper portion 12 may be of any dimension if it forms a continuous opening 18 from the distal end of the hollow prism or cylinder to a similar opening located on the top face. In another preferred embodiment, the upper portion is configured as a hollow prism having the same cross-sectional shape as the top face of the lower portion. In this embodiment, the upper portion is configured as a rectangular prison having the same square cross-sectional shape as that of the square top face 20.
Other variations to the tamper guard 10 are also possible and within the scope of the present invention. For example, the upper portion 12 may be configured so that the continuous opening 18 to the buckle 32 is at an angle generally perpendicular to the quick release mechanism 34. In another embodiment, this angle of the continuous opening 18 may be in a direction away from a child secured in the child safety seat to impede the child accessing the quick release mechanism 34.
Similarly, in a further embodiment, the distal opening 18 of the tubular upper portion 12 may include a cover (not shown) configured to partially cover the continuous opening 18 to impede the child 56 accessing the quick release mechanism 34. The distal opening of the continuous opening 18 may also be bevelled to facilitate access by an adult's finger 54 to the quick release mechanism 34 whilst impeding a child 56 secured in the child safety seat from accessing the quick release mechanism 34.
In another embodiment, the cover may be manufactured from a transparent or translucent material. Similarly, it is to be appreciated that the upper and/or lower portion 12, 14 may be manufactured from a transparent or translucent material to facilitate visually locating the quick release mechanism 34. Alternatively, the cover and/or the upper and/or lower portion 12, 14 may be manufactured from an opaque material, depending on user requirements.
