Abstract: 1. A rescue device (10) for use preferably in traffic accidents or in accidents at sea, wherein the device (10) includes an elongated sheet structure (12, 12') on which, for instance, an injured person is placed, a number of tubular members (14) disposed around the sheet structure (12, 12') and functioning to reinforce or brace the rescue device (10), and a number of carrying means (16) disposed on the sheet structure (12, 12') to enable the rescue device (10) to be carried, characterized in that the sheet structure (12, 12') includes a first stable sheet (20) which is intended to brace the sheet structure (12, 12'), a thermally insulating second sheet (22) having closed pores and disposed adjacent the first sheet (20) and a substantially smooth third sheet (24) which is disposed adjacent the second sheet (22) and centrally opposite the first sheet (20), wherein the third sheet (24) is the sheet on which the injured person is placed. 2. A rescue device (10) according to Claim 1, characterized in that the sheet structure (12, 12') is a unit that includes a first sheet member (12) and two second sheet members (12') that have been produced by bending the sheet structure (12, 12 ) along two longitudinally extending lines (13) and each of which is disposed on a respective side of and along the longitudinally extending sides of the first sheet member (12), wherein the second sheet members (12') define an angle (α) with the first sheet member (12), and wherein the second sheet (22) is slit along the two longitudinally extending lines (13). 3. A rescue device (10) according to Claim 2, characterized in that the carrying device (16) are comprised of apertures (16) disposed adjacent the tubular members (14) in said two second sheet members (12'). 4. A rescue device (10) according to Claim 3, characterized in that the device (10) also includes an attachment means (46) mounted at one short end of the first sheet member (12) and functioning to attach the device (10) to the railing of a boat, for instance, a buoyancy device (50) mounted at the other end of the first sheet member (12), a gas-containing gas source (52) connected to the buoyancy device (50), and an actuator connected to the gas source (52), wherein activation of the actuator causes gas to be delivered from the gas source (52) to the buoyancy device (50) so as to achieve buoyancy. 5. A rescue device (10) according to Claim 3, characterized in that the device (10) also includes insert devices (16') that are intended to be mounted in and fastened to the apertures (16), wherein the insert devices (16') include buoyancy means (16') which are inflated in an activated state to achieve buoyancy. 6. A rescue device (10) according to any one of Claims 1-5, characterized in that the first sheet (20) is preferably an aluminum sheet, the second sheet (22) is preferably a foamed plastic sheet; and in that the third sheet (24) is preferably made of a relatively rigid plastic material. 7. A rescue device (10) according to any one of Claims 2-5, characterized in that the angle (α) is preferably 110 degree . 8. A rescue device (10) according to Claim 4, characterized in that the device (10) also includes hinge means (48) between the first sheet member (12) and the attachment means (46) for enabling the first sheet member (12) to be pivoted in relation to the attachment means (46). 9. A rescue device (10) according to any one of Claims 4, 6-8, characterized in that said attachment means (46) is preferably a hook (46), in that said buoyancy device (50) is preferably a balloon (50); and in that said gas source (52) is preferably a carbon dioxide cylinder (52).
