- the seat structure 1 consists of two independent seating structures 10, 20 arranged side by side in the width direction of the vehicle and having different dimensions: the first seat structure 10 for receiving the back of a single passenger representing approximately 40% of the total width of the seat frame, while the second seat structure 20 can accommodate up to two passengers is about 60% of the same width.
- Each of the seat structures 10, 20 comprises a seat frame 11, 21 and a backrest frame 12, 22 pivotally articulated on this seat 11, 21 along a transverse horizontal axis.
- the seat frame 11, 21 of each seat structure 10, 20 is pivotally mounted forward on the floor of the vehicle about a transverse horizontal axis by means of two pairs of legs 13, 23 welded to the seat. the front of this seat frame 11, 21 and articulated pivotally on two metal legs 14, 24 rigidly moored to the floor 2.
- Each of the seat structures 10, 20 is capable of passing from an extended use position intended to accommodate one or more passengers and in which the rear portion of its seat frame 11, 21 rests against the floor 2 without being fixed thereon, at a position of portfolio setting to maximize the loading volume of the vehicle and wherein the seat frame 11, 21 has tilted forwards in a substantially vertical position with the frame 12, 22 which is folded against it.
- Each seat structure 10, 20 is further associated with a respective anchoring device 30 according to the invention for the removable attachment of a child seat (not shown in the figures) provided with ISOFIX locking metal grippers.
- the anchoring devices 30 each comprise two rectangular anchoring metal rings 40 pivotally mounted pivotably around a same transverse axis on a metal support plate 50 fixed to the floor 2 of the vehicle, as well as two metal holding flanges 70 adapted to cooperate with these anchoring rings 40.
- the two anchoring rings 40 extend on either side of a vertical longitudinal plane of symmetry and are each formed by a single folded wire whose two lower ends are welded. one over the other.
- each ring 40 is preferably steel and has a diameter advantageously between 6 and 10 mm, for example, 7 or 8 mm.
- Each anchoring ring 40 comprises two parallel inner 41 and outer 42 lateral branches, as well as two shorter upper transverse branches 43 and lower (not visible in the figures) and respectively connecting the upper and lower ends of these two lateral branches 41, 42.
- the two transverse branches 43 are straight, while the two lateral branches 41, 42 are slightly curved forwardly at two respective folding zones 41A, 41B, 42A, 42B so as to give a certain forward curvature at each anchoring ring 40.
- the metal support plate 50 is made from a sheet cut and folded.
- Each anchoring ring 40 is pivotally mounted on the latter by its lower transverse branch which passes through a respective transverse hinge bearing 51 formed by folding on the plate 50 between two orifices 52 made by cutting.
- a cylindrical sleeve 53 made of a plastic material having a low coefficient of friction such that the polyacetal (POM) is advantageously interposed between each lower transverse branch and the bearing correspondent 51.
- the fixing of the plate 50 on the floor 2 of the vehicle is here carried out by means of four unrepresented fixing screws passing through circular holes 54 formed in this plate 50.
