| 摘要 |
<p>The invention concerns a structure consisting of a central part (11), designed to receive a user's body, linked by articulations to two lateral parts (12) supporting said central part (11). Said three parts form a single planar element (10) comprising rigid adjacent slats (15) longitudinally linked with one another by a flexible link (16). Each slat comprises two articulations (13a, 13b) and said articulations are arranged so as to define two symmetrical articulating curves (20) which determine the shape, dimensions and profile of the central part (11) relative to the ground when, the structure being folded, that is in position for use, the lateral parts (12) are arranged substantially perpendicular to the ground defining two curved edges (14) resting on the ground. In its unfolded position for storage, the structure is in the form of a planar element capable of being stacked or rolled.</p> |
