Abstract
Abstract A patient''s couch of an X-ray examining apparatus is swingable about its longitudinal axis and is mounted with its front side upon the instrument carrying device. The couch has holding means for the patient. The present invention is characterized by the use of a supporting member having a core consisting of a hard foam substance the cross-section of which is reduced from its longitudinal axis of symmetry toward the two longitudinal edges and ends with an acute angle at these longitudinal edges. The foam core is enclosed by covering layers of firm material of small elasticity and thickness which are joined at least at the longitudinal edges.
