Grill for a land vehicle and also a land vehicle having a grill

1. A land vehicle having bodywork which defines an aperture in which a grill is secured by mounting means wherein the mounting means comprises an elastically deformable non-metallic material which can deform to allow the grill to move relative to surrounding bodywork when the grill receives an impact, thereby absorbing energy of the impact, and which can subsequently return to the original shape thereof and thereby restore the grill to the pre-impact position thereof, characterised in that the mourning means comprises a support substrate having slits extending therethrough rearwardly from a front surface of the substrate which abuts part of the rear surface of the grill.

2. A land vehicle as claimed in claim 1 wherein the grill has a plurality of flanges spaced apart about the periphery thereof, the flanges forming the points of attachment of the grill to the support substrate, the support substrate being attached to rear facing surfaces of the flanges and the support substrate having the slits therein arranged as a plurality of pairs of slits, each pair of slits being associated with one flange, the slits of each pair being spaced apart one on either side of a flange to define therebetween an isolated region in the support substrate isolated from the remainder of the support substrate apart from to the rear thereof, the material in each isolated region deforming when force is transmitted to the isolated region from the flange associated therewith.

3. A land vehicle as claimed in claim 2 wherein the support substrate is formed from a foam material.

4. A land vehicle as claimed in claim 2 wherein the support substrate comprises at least one moulded component.

5. A land vehicle as claimed in claim 4 wherein the moulded component is moulded to a shape which at least in part matches the front external shape of the automobile.

6. A land vehicle as claimed in claim 3 wherein the support substrate comprises two moulded components.

7. A land vehicle as claimed in claim 1 wherein the grill is non-metallic.

8. A land vehicle as claimed in claim 7 wherein the grill is composed of a composite material.

9. A land vehicle as claimed in claim 8 wherein the grill is formed from a fibre reinforced polymeric material.

10. A land vehicle as claimed in claim 9 wherein the grill is formed from glass fibre reinforced nylon.

11. A land vehicle as claimed in claim 10 wherein the grill is a one-piece moulded component.

12. A land vehicle as claimed in claim 1 , wherein the grill is composed of a composite material comprising fibres set in a matrix, the grill comprising a central mesh region supported and surrounded by a continuous perimeter, wherein the central mesh region comprises:

a first plurality of spaced apart parallel slats which extend generally horizontally when the grill is secured in the aperture in the bodywork; and

a second plurality of spaced apart parallel slats which extend perpendicularly to the slats of the first plurality and which extend generally vertically when the grill is secured in the aperture in the bodywork;

and wherein the slats of the second plurality have a depth which is greater than the depth of the slats of the first plurality.

13. A land vehicle as claimed in claim 12 wherein leading edges of the slats of the second plurality are located rearward of the leading edges of the slats of the first plurality and the rearward edges of the slats of the second plurality are spaced behind the rearward edges of the slats of the first plurality.

14. A land vehicle as claimed in claim 12 wherein the composite material comprises glass fibres set in a nylon matrix.

15. A land vehicle as claimed in claim 12 wherein said grill is a one-piece moulded component.

16. A land vehicle as claimed in claim 12 wherein said grill further includes a plurality of flanges which extend outwardly from the perimeter.
