Abstract
The invention relates to a stretcher comprising first and second support arms to which and between which a means for receiving an individual is intended to be attached, said first arm comprising first and second end elements, and also a first cable attached to said end elements in order to be tensioned between these in a first longitudinal direction, said stretcher comprising a first crosspiece connected to said first and second arms, positioned between the latter and designed to change between retracted and deployed configurations, such that, in the retracted configuration, said first element and first crosspiece are connected by a mechanical connection permitting a degree of freedom in translation in said first direction, and such that, in the deployed configuration, said connection inhibits said degree of freedom. The invention is particularly suitable for the production of stretchers having a reduced size when not in use.
