1. Hinge constituted by a first (1) and by a second (6) body mounted for pivoting one with respect to the other, and by a locking pin (22) for locking the relative position of said first and second bodies, which hinge : - is radially set off from the pivoting axis (11), - is coupled (31) to the first body (1), - is permanently fast in rotation therewith, - is mounted for sliding on said first body in a direction parallel to the pivoting axis (11), - has a free end (42) which is placed opposite a face (9) defining the second body, and - is provided with a member (34) controlling a sliding movement to move it apart from the said face, whereas at least one housing (33) is provided in the second body (6), that each housing (33) issues into the said face (9) of the second body (6) and is adapted to receive at least part of the locking pin (22) in a predetermined relative position of the first and second bodies (1 and 6), called locking position, that an elastic return member (41) is coupled between the locking pin (22) and one of the first (1) and second (6) bodies, and that a pressure applied on the free end (42) of the locking pin (22) towards the said face (9) of the second body (6) can cause the automatic introduction of said locking pin (22) in each housing (33), in the corresponding position locking the first and second bodies (1 and 6), and that the maximum spacing (E) controlled by the member (34) controlling the sliding movement of the locking pin (22) is at least equal to the depth (P) to which the locking pin (22) is sunk into each housing (33), thus allowing from a locking position the unlocking of the position of the first and second bodies (1 and 6), characterized in that the locking finger (22) is axially made fast (21 to 28) with a pivoting shaft (5) already fast in rotation with the first body (1) and on which the second body (6) is pivotally mounted so that a thrust exerted via the control member (34) on said pivoting shaft (5) causes the release of the locking finger (22) from the housing (33) provided in the second body (6), thus ensuring the unlocking of the hinge and permitting the pivoting movement of the two bodies (1 and 6) one with respect to the other before reaching another locked position. |
