There is provided a protection structure for a gas cylinder assembly comprising a gas cylinder body and a valve. The gas cylinder body includes a base and a neck to which a proximal end of the valve is connectable in use. The protection structure comprises first and second structural sections, the first section being connectable to the valve such that the second section is spaced from the valve by the first section. Further, in use, the second section is arranged to transfer impact forces to the first section, and the second section is arranged to deform with respect to the second section in response to said impact forces to reduce the peak impact force on the valve.

1. A protection structure for a gas cylinder assembly comprising a gas cylinder body and a valve, the gas cylinder body including a base and a neck to which a proximal end of the valve is connected in use, the valve having a housing, an outlet, an integrated pressure regulator, a fill port, and a distal end remote from the gas cylinder body that forms a top surface of the gas cylinder assembly, the protection structure comprising: a first hollow section having a closed lower end connectable to the top surface of the gas cylinder assembly at the distal end of the valve and extending further distal from the cylinder body, the first hollow section having an open upper end;a second hollow section arranged in a stacked configuration on the first section such that the second section is further distal from the gas cylinder body than the first section and is spaced from the valve by the first section, the second hollow section having an open lower end connected directly to and in contact with the open upper end of the first hollow section and an upper open end distal from the first hollow section,wherein, in use, the second section is arranged to transfer impact forces to the first section, and the first section is arranged to deform with respect to the second section in response to said impact forces to reduce the peak impact force on the valve. 2. A protection structure according to claim 1, wherein first section comprises a tapered section. 3. A protection structure according to claim 1, wherein the second section is substantially cylindrical. 4. A protection structure according to claim 1, wherein the first and second sections are connected by mating flanges. 5. A protection structure according to claim 1, wherein at least one of the first and second sections is formed from mild steel. 6. A protection structure according to claim 1, wherein the second section is formed from a thicker or harder material than the first section. 7. A protection structure according to claim 6, wherein the second section is formed from thicker material than the first section, the material having a yield stress in the range of 100-250 MPa. 8. The protection structure of claim 1, further comprising a guard body that is arranged, in use, to surround the valve and protection structure, at least a portion of the guard body being supported by the protection structure. 9. A protection structure according to claim 8, wherein the guard body comprises first and second clamshell portions arranged to connect directly to the protection structure. 10. A protection structure according to claim 8, wherein the guard body is formed from a plastics material. 11. A valve assembly comprising a proximal end connectable to a gas cylinder and a distal end comprising a protection structure according to claim 1. 12. A valve assembly according to claim 11, wherein the protection structure is connected to the distal end of the valve assembly by removable or permanent fixings. 13. A gas cylinder assembly comprising a gas cylinder body and a valve assembly according to claim 11. 14. A valve assembly of claim 11, further comprising a guard body that is arranged, in use, to surround the valve and protection structure, at least a portion of the guard body being supported by the protection structure. 15. A valve assembly according to claim 14, wherein the guard body comprises first and second clamshell portions arranged to connect directly to the protection structure. 16. A gas cylinder assembly according to claim 13, wherein the valve assembly further comprises a guard body that is arranged, in use, to surround the valve and protection structure, at least a portion of the guard body being supported by the protection structure. 17. A gas cylinder assembly according to claim 16, wherein the guard body comprises first and second clamshell portions arranged to connect directly to the protection structure.
