AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant (s): ARB CORPORATION LIMITED A.C.N. 006 708 756 Invention Title: IMPROVED VEHICLE PROTECTION SYSTEM The following statement is a full description of this invention, including the best method of performing it known to us: P/00/001 Section 29
AUSTRALIA
2. IMPROVED VEHICLE PROTECTION SYSTEM Field of the Invention This invention relates to improvements in vehicle protection systems, such as systems of the type commonly known as bull bars, brush guards or grille guards. Background of the Invention Most bull bars/brush/grille guards are either rigidly mounted to the frame or bumper bar of a vehicle. This rigid mounting of the bar/guard can result in damage if a structure, vehicle or person is struck by the bar/guard. In addition, impacts of the type which are often encountered in normal driving can result in activation of the airbag protection system resulting in an undesirable cost for the owner. Summary of the Invention and Object It is an object of the present invention to provide an improved vehicle protection system which has the effect of reducing damage to the bar/guard and to anything the bar/guard may contact, including pedestrians. The invention therefore provides a vehicle protection system comprising a structure for protecting the vehicle, mounting means adapted for attachment to the vehicle, said mounting means incorporating restorable deflection means adapted to receive an upstanding portion of said structure and to allow the structure to deflect angularly from its upstanding state under a predetermined load to thereby reduce damage while continuing to protect the vehicle. In one form, the restorable deflection means includes a flexible or resilient mount to which the structure is attached. The flexible or resilient mount may comprise a moulded rubber or deformable plastics member having a configuration which allows the member to deform to absorb impacts with a controlled deflection of the structure. In the case of severe impacts, the structure will again become rigid at the end of its allowed deflection to thereby adequately protect the vehicle against the impact.
3 While the embodiment described below is limited to a vehicle protection system, it will be appreciated that the same system may be adapted to protect any part of the vehicle. Brief Description of the Drawings In order that the invention may be more readily understood, one embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 is a sectional side elevation of a vehicle frontal protection system embodying the invention, and Figure 2 is a similar sectional elevation showing deformation of the mount under impact. Description of the Preferred Embodiment Referring to the drawings, the vehicle frontal protection system embodying the invention includes a resilient mount 1 received within a socket 2 in a vehicle frame member or bumper bar 3. The mount 1 has a socket 4 which receives the lower end of a bull bar structure 5 which is held in the socket by means of an anchoring nut 6. In the embodiment shown, the resilient mount 1 is moulded rubber or deformable plastic having a series of cavities 7 of increasing depth which allow the mount 1 to be progressively deformed under an impact load L applied to the structure 5. The effect of an impact load on the mount 1 is illustrated in Figure 2 of the drawings. When the 30 structure 5 is unable to deform the mount 1 further, it becomes rigid to thereby protect the vehicle in the usual manner. However, the ability of the structure 5 to deflect reduces the damage caused to property or persons in the event that the impact is not significant. As a result of the resilient mounting of the structure 5 in the manner described above, damage to the -4 structure 5 and to anything the structure may contact, including pedestrians, is significantly reduced. In the claims of this application and in the description of the invention, except where the context 5 requires otherwise due to express language or necessary implication, the words "comprise" or variations such as "comprises" or "comprising" are used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further 10 features in various embodiments of the invention. Since modifications within the spirit and scope of the invention may be readily effected by persons skilled in the art, it is to be understood that the invention is not limited to the particular embodiment described, by way 15 of example hereinabove.

Claims (8)
1. A vehicle protection system comprising a structure for protecting the vehicle, mounting means adapted for attachment to the vehicle, said mounting means incorporating restorable deflection means adapted to receive an upstanding portion of said structure and to allow the structure to deflect angularly from its upstanding state under a predetermined load to thereby reduce damage while continuing to protect the vehicle.
2. The system of claim 1, wherein the restorable deflection means includes a flexible or resilient mount to which the protecting structure is attached.
3. The system of claim 1 or 2, wherein the restorable deflection means includes a moulded resilient member having a deformable portion which is deformed by the application of the predetermined load to the structure.
4. The system of claim 3, wherein moulded resilient member is a sleeve having said deformable portion and a socket for receiving said upstanding portion of said structure such that application of the predetermined load in the direction of said deformable portion causes deformation thereof.
5. The system of claim 3 or 4, wherein said deformable portion becomes rigid after a predetermined deformation occurs, such that the protecting structure provides protection for the vehicle.
6. The system of any one of claims 3 to 5, wherein the deformable portion is formed with a series of cavities of increasing depth, the portions of the deformable portion adjacent the cavities of maximum depth being more deformable than the portions adjacent the cavities of minimum depth, whereby the mount is progressively deformable as the load applied to the structure increases.
7. The system of any preceding claim, wherein the restorable deflection means is moulded from rubber or deformable plastics. 6
8. A vehicle protection system substantially as hereinbefore described with reference to the accompanying drawings.
