While the invention is described in connection with such embodiments, it should be understood that the invention is not limited to any embodiment. On the contrary, the scope of the invention is limited only by the appended claims and the invention encompasses numerous alternatives, modifications and equivalents. For the purpose of example, numerous specific details are set forth in the following description in order to provide a thorough understanding of the present invention. [0032] In order to further understand the invention, preferred embodiments, will now be described. However, it will be realised that the scope of the invention is not be confined or restricted to the details of 5 the embodiments described below. Variations and alterations that would be readily apparent to a person skilled in the art are deemed as being incorporated within the scope of the invention. BRIEF DESCRIPTION OF DRAWINGS [0033] Embodiments of the present invention will be discussed with reference to the accompanying drawings wherein: [0034] Figure 1 is an isometric view of a child restraint assembly; [0035] Figure 2 is an isometric view of a seat body from the assembly of Figure 1; [0036] Figure 3 is an isometric view of a cushioning element from the assembly of Figure 1; [0037] Figure 4 is an isometric view of a headrest assembly for a child restraint; [0038] Figure 5 is an isometric view of a headrest body from the headrest assembly of Figure 4; and [0039] Figure 6 is an isometric view of a cushioning element from the headrest assembly of Figure 4. [0040] In the following description, like reference characters designate like or corresponding parts throughout the figures. DESCRIPTION OF EMBODIMENTS [0041] The present invention will be described below in relation to a Type-B and/or E child safety seat for use in a vehicle in a forward facing manner. However, it will be appreciated that the present invention could be equally applicable for use in a variety of different modes of child safety seats, including Type A/B, Type A/B/E etc, and still fall within the spirit of the present invention. [0042] Referring now to Figures 1 and 3, where there is illustrated a child restraint in the form of a child safety seat 1 for use with a seatbelt equipped vehicle seat by being positioned thereon and retained thereto using the vehicle's seat belts and, optionally, a tether strap extending from the child safety seat 1 to a vehicle mounting point. [0043] The child safety seat 1 comprises a seat body 2 (also commonly referred to as a shell) for receiving an occupant, which comprises a base or seat portion 4, a back portion 6, and a pair of side wings 8 extending forward of the back portion 4 and upward from the base portion 6. The side wings 8 provide a 6 physical barrier to provide a degree of side protection to the occupant, and limit their sideways movement. The seat body 2 thus defines an interior for receiving an occupant, and an exterior. [0044] The seat body 2 will generally be formed from blow or injection moulded plastic, but is not so limited. [0045] With reference to Figure 3, it can be seen that each of the side wings 8 comprises an aperture 10 through an upper portion thereof, and an aperture 12 through a lower portion thereof, each aperture 10 and 12 extending from the interior to the exterior of the respective side wing 8. [0046] There is for each side wing 8 a cushioning element 20 depending therefrom so as to form a cushioned liner for the interior of the side wing 8. [0047] In this embodiment each cushioning element 20 comprises a lining providing body 21, and a pair of outwardly projecting cushioned portions 22 and 24 which are both positioned and shaped to nest in and extend through the respective apertures 10 and 12 in the side wings 8 of the seat body 2, and sit proud of and thereby provide cushioning for the seat body 2 exterior. [0048] The cushioning elements 20 comprise a thin walled flexible plastic shell which may be any one of hollow, partially or fully gas, liquid or gel filled, or contains or is filled with an energy absorbing material such as a foamed plastic or cellular material or the like. Further still, a combination of fillings may be employed. [0049] In addition to providing a cushioned lining of its respective side wing 8, each cushioning element 20 provides external cushioning useful for the purpose of absorbing energy associated with impacts incident to the exterior of the seat body 2. What is more, these outwardly projecting cushioned portions 22 and 24 provide cushioning for other vehicle occupants who may be sitting alongside of the subject child restraint 1. Significantly then, the present arrangement provides for both interior and exterior cushioning of the child restraint 1 without significantly increasing the thickness of the side wings 8 of the same. [0050] Child safety seat 1 may comprise a further cushioning structure, layer, layers, and/or a cushioning cover (not illustrated), that could be attached to or extend over all or portions of the cushioning elements 20 to alter their response to impacts and provide different characteristics to absorb energy. Materials such as any one or more of open or closed cell foams, expanded polystyrene, or other suitable energy absorbing materials may be employed in such a layer, layers or cover. A cushioning structure may be entirely or partially collapsible.
7 [0051] Referring now to Figures 4 and 6, where there is illustrated a headrest assembly 100 for a child restraint 1, which will in use be positionably adjustable with respect to a back portion 2 of the child restraint 1, for the purpose of accommodating growth of the occupant. [0052] The seat body (not illustrated) from which headrest assembly 100 depends may be similar to seat body 2 described above, in as much as it comprises further cushioning elements, such as those illustrated at 20 in Figures 1 and 2. [0053] The headrest 100 comprises a headrest body 102 having a back portion 106, and a pair of side wings 108 extending forward therefrom so as to extend on each side of a seat occupant's head. [0054] The headrest 100 defines an interior between the side wings 108 for receiving the occupants head, and an exterior. [0055] Each of the side wings 108 comprises an aperture 110 (see Figure 6) extending from the interior to the exterior of the respective side wing 108. [0056] Referring now to Figures 4 and 5, where there is illustrated a cushioning element 120 depending from the headrest body 102 so as to form a cushioned liner for this, which functions to provide energy absorption to reduce the severity of an impact between the child's head and the headrest body 102. [0057] In this embodiment the headrest cushioning element 120 comprises a cushioned back portion 122 and a pair of cushioned side wing portions 124, each of which comprise outwardly projecting cushioned portions 126 which are both positioned and sized to nest in and extend through the apertures 110 in the respective side wings 108 of the headrest body 102, and sit proud of and thereby provide cushioning for the headrest body 102 exterior. [0058] The cushioning element 120 comprises a thin walled flexible plastic shell which may be any one of hollow, partially or fully gas, liquid or gel filled, or contains or is filled with an energy absorbing material such as a foamed plastic or cellular material or the like. Further still, a combination of fillings may be employed. [0059] Headrest assembly 100 may comprise a further cushioning structure layer, layers, and/or a cushioning cover (not illustrated), that could be attached to or extend over all or portions of the cushioning element 120 to alter its response to impacts and provide different characteristics to absorb energy. Materials such as any one or more of open or closed cell foams, expanded polystyrene, or other suitable energy absorbing materials may be employed in such a layer, layers or cover. A cushioning structure may be entirely or partially collapsible.
8 [0060] In addition to providing a cushioned lining of the head rest, the cushioning element 120 provides external cushioning useful for the purpose of absorbing energy associated with impacts incident to the head rest body 102. Significantly, the present arrangement provides for both interior and exterior cushioning of the headrest 100 without significantly increasing the thickness of the side wings 108 of the same. [0061] Throughout the specification and the claims that follow, unless the context requires otherwise, the words "comprise" and "include" and variations such as "comprising" and "including" will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers. [0062] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement of any form of suggestion that such prior art forms part of the common general knowledge. [0063] It will be appreciated by those skilled in the art that the invention is not restricted in its use to the particular application described. Neither is the present invention restricted in its preferred embodiment with regard to the particular elements and/or features described or depicted herein. It will be appreciated that the invention is not limited to the embodiment or embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the invention as set forth and defined by the following claims.
