DETAILED DESCRIPTION OF THE DRAWINGS

(10) Referring now to FIG. 1 there is shown Examples A, 10, and B, 12, which are embodiments of the subject invention intended to be deployed by unrolling or unfurling under gravity from externally mounted storage and deployment means on the vehicle (not shown). It will be noted the plurality of panels will be made from a reflective heat dissipating and/or thermal insulating material or textile. A preferred material is flexible woven silica. The material may also include a metallised layer 13 made from aluminium film, aluminium foil or stainless steel foil that is capable of reflecting about 95% of radiant heat contacting its surface (see FIG. 8). Additionally, the material has a density ranging from 474 gsm to 1,864 gsm and a thickness of 0.5 mm to 3.2 mm.

(11) Each panel configured to cover an adjacent portion of the cabin of the vehicle (not shown). The straps or tags 14, 16, 18, 20, 22 provide for retention means to secure the panels by gripping between the shut doors and door frames of the cabin of the vehicle (not shown).

(12) In one embodiment, the straps or tags 14, 16, 18, 20, 22 may extend between and connect adjacent panels to provide the retention means. The retention means is extendible into the vehicle cabin and is accessible by an occupant of the vehicle. The straps or tags may be used to adjust the cover against the vehicle cabin or body, for example, by either tightening or loosening the straps or tags. This allows an occupant of the vehicle to safety adjust the cover while under the cover.

(13) It should be appreciated that the term “vehicle” used throughout the specification has the general meaning portrayed to the person skilled in the art. However, such is intended to also include, but not limited to, people movers or personal use motor vehicles, emergency personal vehicles, caravans, trailers, or any other vehicle or body that may be occupied by personnel, when they become trapped in a fire situation.

(14) Referring now to FIG. 2A the general shape of a crew or single cabin area of a fire fighting vehicle is shown, with which the invention may be used. In FIG. 2B, the cover, A, 10, as depicted in FIG. 1, is shown to be mounted onto the roof of the vehicle within an enclosed, hinge-lidded, elongated container 24. The container 24 is one example of a storage and deployment means designed to effect rapid deployment of the cover.

(15) In FIGS. 2C and 2D, Example A 10 is shown to have unrolled and unfurled from storage and deployment container 24. Panels 10a, 10b, 10c and 10d are shown to have unfolded from their position above base panel 10e. In the interests of clarity, the straps or tabs which provide for retention means are not shown.

(16) It will be noted from FIG. 2E, that when Example A 10 is deployed, panel 10a will overlap with panel 10b, panel 10c will overlap with panel 10d, panel 10c will overlap with panel 10e and panel 10b will overlap with panel 10e. The fire protective cover will take a substantially rectangular shape encompassing or enclosing the cabin or body section of a vehicle, thereby protecting the cabin or body and its occupants from exposure to radiant heat, burning embers and flames. It will be obvious that the shape and dimensions of the panels will correspond to the type and make of the vehicle for which the cover is intended.

(17) Referring now to FIG. 3 there is shown another preferred embodiment of the subject invention, Example C which is intended to be deployed by unfolding out from a compact arrangement (not shown). It will be noted the plurality of reflective panels intended to be made from a heat dissipating and/or thermal insulating material or textile, each panel configured to cover an adjacent portion of the cabin of the vehicle (not shown).

(18) 26 a-g indicate the location of torsion springs, which is one example of a mechanical aid used to effect deployment of an unfolding cover. These torsion springs may be selectively varying strengths to assist in rapidly unfolding panels 26B, 26C, 26D, 26E, 26F, 26G and 26H in a successive, predetermined order from base panel 26A to cover the vehicle (not shown). When stored, the panels are folded against the bias of the springs and retained in place in a storage and deployment container strategically located on the vehicle (not shown). Automatic deployment of the cover is preferably triggered by a mechanism accessible within the vehicle such as a manual switch or an automatic trigger based on a thermostat or fusible link responsive to ambient temperature (not shown) operating a retaining pin or solenoid device (not shown).

(19) While in the above explained embodiment reference is made to torsion springs as a preferred deployment mechanism, it shall be appreciated that other known mechanical deployment mechanisms can be used without departing from the spirit of the present invention. In particular, it is envisaged that a pneumatically powered system could be used to impart rapid deployment of an unfolding cover of the present invention. Additionally, a compressed air deployment system, mechanical gearing, electric motors and hydraulic energy are other examples of systems that could be adapted to impart rapid deployment of the cover of the present invention.

(20) In use and after deployment of the cover, straps or tags 28, 30, 32, 34, 36, 38, 40, 42 may be used to further secure the panels by gripping between shut doors and door frames of the cabin of the vehicle (not shown).

(21) Referring now to FIG. 4 there is shown one example of a shape of a vehicle 44, The cover, C, 26, is shown to be mounted (method not shown) onto the roof of the vehicle 44. Obviously the shape and dimensions of the panels will correspond to the type and make of the vehicle for which the cover is intended to be used with. Panels 26B, 26C, 26E, 26F and 26H are shown to be unfolding from base panel 26A. Panels 26D and 26G also unfold from base panel 26A, but are not shown. In the interests of clarity, the straps or tabs which provide for the retention means are not shown. Panel 26B will overlap with panel 26D (not shown), panel 26D (not shown) will overlap with panel 26G (not shown), panel 26G (not shown) will overlap with panel 26H, panel 26H will overlap with panel 26 E, panel 26D will overlap with panel 26C and panel 26 C will overlap with panel 26B. The fire protective cover of the present invention, in preferred embodiments, will take a substantially rectangular shape encompassing or enclosing the cabin section or body of the vehicle 44, thereby protecting the cabin or body and any of its occupants from exposure to radiant heat, burning embers and flames. It will be obvious that the shape and dimensions of the panels will correspond substantially to the type and make of the vehicle for which the cover is intended to be used with.

(22) In all the above examples, the deployment is preferably triggered by a mechanism accessible within the vehicle, such as a manual switch or an automatic trigger based on a thermostat or fusible link responsive to ambient temperature (not shown) operating a retaining pin or solenoid device. During housing in the stored position for extended periods of time, the torsion springs may lose some tension, however it is envisaged that replacement springs may be installed when too much spring tension is lost. Moreover, other deployment mechanisms can be replaced if necessary during the life of the product.

(23) FIG. 5 illustrates a base panel 50 comprising a roof panel 52, rear window panel 54 and front window panel 56 which are joined together, for example by stitching. The roof panel 52 includes excess material in the form of flaps 52A and 52B which overlap the edges of the roof adjacent to the doors such that flaps 52A and 52B can be gripped between a closed door and a door frame. The rear window panel 54 includes flaps 54A and 54B which overlaps the edges of the rear window adjacent to the doors such that flaps 54A and 54B can be gripped between a closed rear door and the door frame.

The front window panel 56 includes flaps 56A and 56B which overlap the edges of the front window adjacent to the front door such that the flaps 56A and 56B can be gripped between a closed front door and the door frame. Flaps 52A-B, 54A-B, 56A-B have a width of ranging from 70-700 mm. Suitably, the flaps 52A-B, 54A-B, 56A-B extend about 70-75 mm from the perimeter of the base panel 50.

(24) FIG. 6 illustrates a front door side panel 58 comprising front door panels 58A and 58B. Cuffs 60A-C of the front door side panel are securable to the upper edge of the front door. Panel 58A further includes cuffs 64A and 64B which are securable to the side edge of the front door and a flap 62 which extends beyond the side edge of the front door and overlaps the rear door panel. The cuffs have a width of about 75 mm.

(25) Panel 58A includes opening 66 to allow an occupant to see the external environment and opening 68 to provide access to the door handle. These openings 66 and 68 are covered by flaps which are attachable to the side panel.

(26) FIG. 7 illustrates a rear door side panel 70 including cuffs 70A and 70B which are securable to the side edge of the rear door and a flap 72 which extends beyond the side edge of the rear door.

(27) The base panel 50, front door side panel 58 and rear door side panel 70 are connected by hook and loop fasteners 51. It can be appreciated that these panels can be connected by other means including stitching and riveting.

(28) FIG. 8 illustrates a fire protection external vehicle cover including a base panel connected to the front door side panel of FIG. 6 and the rear door side panel of FIG. 7. The rear window panel 54 includes straps 41 and 43 which can be gripped between the door and door frame of the cabin of the vehicle to secure the panel to the vehicle. Front door side panel 58 includes overlapping flap 64 that is arranged to overlap the rear door side panel 70. The front door side panel 58 includes open cuff 67 that is arranged to extend inward of an outer face of the side panel and overlay the outer face of the side panel to form an elongate opening to receive edges of the vehicle door. Rear door side panel 70 includes overlapping flap 72 to overlap the rear cabin “C” pillar. The rear door side panel 70 includes open cuff 73 that is arranged to extend inward of an outer face of the side panel and overlay the outer face of the side panel to form an elongate opening to receive edges of the vehicle door. Gusset 5 connects front window panel 56 and base panel 52. The gusset improves flexibility of the cover by providing fold lines to allow the cover to fold and minimize stress on adjacent panels by increasing the distance between these panels to allow the cover to be folded without abutting the edges of the two panels.

(29) Retention means 23 connects front window panel 56 and front door side panel 58.
