Stretcher support device with a bogie, the latter being designed to be connected to the structure of a vehicle such that the stretcher support device is arranged in a loading space of the vehicle, with a bottom frame, which is arranged on the bogie and is rigidly connected to the latter, wherein the bottom frame has a front end and a loading end and extends between these parallel to a floor surface, with a middle frame, which has a first end and a second end and which is mounted displaceably on the bottom frame in such a way that it can be moved relative to the bottom frame between a retracted position, in which the middle frame is arranged over the bottom frame so that the first end of the middle frame is arranged at the front end and the second end of the middle frame is arranged at the loading end, and a deployed position, in which the middle frame extends beyond the loading end, with a top frame, which has a flat loading surface and also a first end and a second end and which is mounted displaceably on the middle frame in such a way that it can be moved relative to the middle frame between a retracted position, in which the top frame is arranged over the middle frame so that the first end of the top frame is arranged at the first end of the middle frame and the second end of the top frame is arranged at the second end of the middle frame, and a deployed position, in which the top frame extends beyond the second end of the middle frame, wherein the bottom frame has a first guide, which extends between the front end and the loading end and along which at least the first end of the middle frame is guided displaceably, wherein the loading end has a first supporting element, on which a first support rail of the middle frame is supported, said first support rail facing towards the floor surface and extending between the first end and the second end of the middle frame, wherein the middle frame has a second guide, which extends between the first end and the second end and along which at least the first end of the top frame is guided displaceably, wherein the second end of the middle frame has a second supporting element, on which a second support rail of the top frame is supported, said second support rail facing towards the floor surface and extending between the first end and the second end of the top frame, and wherein the course of the second support rail between the first end and the second end of the top frame is such that the angle (α), which the loading surface encloses with the middle frame, decreases when the top frame is moved from the retracted position to the deployed position. with a bottom frame, which is arranged on the bogie and is rigidly connected to the latter, wherein the bottom frame has a front end and a
