DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a tonneau cover device according to the present invention, and FIG. 2 is a sectional view showing an attached state. The tonneau cover device 10 of the present invention is arranged on a tonneau portion T for luggage storage behind the rear seat 50 of the automobile,
The main cover 20 covers the tonneau part (pull-out / wind-up) so that the luggage on the tonneau part cannot be seen from the outside. The material of the main cover 20 is a material used for a conventional tonneau cover, such as a resin sheet such as a vinyl chloride resin, a woven fabric, or a laminate thereof. The main cover is wound and stored in the storage case 40.
The storage case 40 is formed by extrusion molding of a resin, bending molding of a steel plate, extrusion molding of a metal, or the like, has a substantially horizontal concave shape, and has an opening 42 as an outlet of a main cover facing the rear of the vehicle. Then, the main cover is wound up and stored in the winding shaft inside. The winding shaft is urged by an elastic means (not shown) to always wind the main cover into the storage case. With the gripping side 21 formed at the edge of the main cover, pull out the main cover from the inside of the storage case, lock it to the back door, cover the tonneau part, and release the lock to automatically take up the winding shaft. It is wound and stored in the storage case.
The storage case is arranged behind the rear seat, and both ends are supported by the side of the vehicle.

There is a gap S for reclining the rear seat between the storage case and the rear seat, and a sub cover 30 is arranged to cover this gap. The material of the sub-cover 30 is the same as the material of the main cover, but a more flexible, preferably stretchable sheet material is preferable. One edge 31
Is fixed to the outer surface 40a of the storage case, and the opposite edge 32 is locked to the rear seat. If the rear seat is reclining right and left, a slit 35
Or divide the subcover into two. The lock between the sub-cover and the rear seat is preferably easy to remove, and one preferred embodiment has a plurality of openings 42 at the edge of the sub-cover that locks to the rear seat, and the rear seat once removes the upper headrest 51. Then, there is a method in which the edge of the sub cover is placed, and the headrest is returned to the rear seat and locked again so that the leg portion 52 of the headrest is inserted into the opening of the edge.

To fix the sub cover to the outer surface of the storage case, a groove 41 is formed in the outer surface of the storage case, and the wire rod 33 is fixed.
And embeds and fixes the edge 31 of the sub-cover which is thickened by winding. One of the end caps 44 at both ends of the storage case is once removed, the thickened edge of the sub cover is slid into the end edge of the storage case from which the end cap has been removed, and then the end cap is fitted. The method of forming the concave groove in the storage case is determined by the shape of the extrusion die when the storage case is a resin extruded product or a metal extruded product, and required when the storage case is a bent steel plate product. To form a groove. The groove has a substantially circular cross section (1 to 8 mm in diameter), and has an opening smaller than the diameter of the circle (30 to 80% of the diameter of the groove cross section) and opens in the rear seat direction.

Wire rod 3 used for thickening the edge of the sub cover
3 is preferably a steel wire, and a resin extruded product or the like is also suitable. The diameter of the wire is at least smaller than the cross-sectional diameter of the groove, and the diameter of the thick edge formed by winding the wire with the sub cover is set to be smaller than the diameter of the groove and larger than the opening of the groove. When the wire is wound by the sub-cover, the wire is placed on the back surface near the edge of the sub-cover in parallel with the edge, the edge of the sub-cover is folded, and the wire is sandwiched by the cover. Further, the folded back cover edge and the sub cover are bonded together on the back surface. Adhesion between the edge of the sub-cover and the sub-cover can be selected from high-frequency welding, adhesive bonding, sewing, and the like depending on the material of the sub-cover. 5A and 5B show another embodiment of the present invention. FIG. 5A shows a case in which two concave grooves 45 and 45 'are formed in a storage case, and sub-covers 30 of different (or the same) materials are respectively formed. In this case, one sub-cover can be used as a shade by mounting the opposite edge of the sub-cover in the direction of the ceiling of the vehicle. This is an example in which two sub-covers are attached. Also, in another embodiment (not shown), the sub-cover is pleated to make it bellows, and even when the rear seat is larger reclining,
Use a sub cover without slack. Alternatively, it is conceivable to use a sub cover made of an elastic material.

[0010]

According to the present invention, a tonneau cover device with a sub cover having a light weight and a simplified structure is provided. The flexible sub-cover prevents the sub-cover from breaking or wrinkling even when the rear seat is reclined, thereby impairing the appearance. The adoption of a flexible sub-cover prevents transmission of impact to the rear seat occupant by the sub-cover in the event of a rear-end collision. The sub-cover can be removed and can be washed.
