DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat back pocket structure, and more particularly, to a lower end of a back side of a trim cover of a seat back, and a rear side of the trim cover from a front side of the trim cover through a lower end of the seat back. The present invention relates to a seatback pocket structure in which a front lower terminal extending to the side is locked by a hook member, and a pocket portion is provided on a rear side of the seatback trim cover.

[0002]

2. Description of the Related Art In general, in a vehicle seat or the like, a pocket body made of a synthetic resin or a net is provided on the back side of a front seat back, and a rear seat occupant is positioned along the back side of the seat back. By pulling out the pocket body or opening the upper opening of the net, magazines, newspapers, small articles, etc. can be stored and used, thereby improving the livability in the passenger compartment.

In a conventional pocket structure of a seat back, as shown in FIGS. 4 and 5, a pocket body 5 made of fabric or the like is attached to a lower portion on the back side of the seat back 1, and an opening 5a side of the pocket body 5 is provided. At the upper end, a string body 7 such as an elastic rubber string is attached,
The opening 5a is formed so as not to be opened. In the skin material 3 as a trim cover on the back side of the seat back 1, the upper skin material 3a is formed of an expensive material, for example, fabric, and the lower skin material 3b, which is a portion facing the inside of the pocket body 5, is made of non-woven fabric or tricot. It is formed from inexpensive materials such as. The sewn portion 3c of the upper skin material 3a and the lower skin material 3b is formed at a position close to the opening 5a at the upper end of the pocket body 5.

As a conventional seat back pocket structure, as shown in Japanese Utility Model Registration No. 2548267, a net is provided on the back of the seat back board via a mounting frame, As disclosed in Japanese Patent Application Laid-Open No. 175273/175, a pocket is constituted by a pocket sheet, a fastening means is provided at an intermediate portion inside the pocket, and the pocket can be used at two different depths. As disclosed in Japanese Patent Application Laid-Open No. 11-59280, an inner pocket sheet and an outer pocket sheet are used to improve the appearance of pockets in which small articles are placed by eliminating outward bulges. As shown, the pocket recess formed in the backboard is covered with a lid that is rotatable about its lower end to form a pocket. Etc. exist.

[0005]

However, in a conventional pocket structure of a seat back, as shown in FIG.
The opening 5a at the upper end of the pocket body 5 is opened against the tension of the cord body 7 having elasticity. By opening the opening 5a, a nonwoven fabric, a tricot or the like facing the inside of the pocket body 5 is opened. The lower skin material 3b, which is an inexpensive material part, is exposed to eliminate the sense of quality, and the lower end of the upper skin material 3a as a trim cover made of an expensive material on the back side of the seat back 1 above the pocket body 5 is formed. The sewing line of the sewing portion 3c with the lower skin material 3b is exposed, which impairs quality. Further, a double inner and outer skin material is required to form the pocket body 5, and the number of sewn portions is increased, which has the disadvantage of increasing costs.

Further, in the conventionally known pocket structure of a seat back, the work of extending a net through a mounting frame becomes complicated, and a pocket structure having two different depths, an inner pocket seat, and an inner pocket seat. When the outer pocket sheet is used, the configuration becomes complicated, the assembling work becomes complicated, and the cost is increased.

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple structure with a minimum required number of components, and to perform an assembling operation simply and quickly.
It has excellent pocket shape retention, reduces the amount of trim cover used, reduces the number of sewn parts, allows easy access to stored items such as cartographers, and allows stored items to be viewed at a glance from the outside. The present invention is to provide a seat back pocket structure which can be confirmed, can securely hold stored items, can improve appearance without fear of falling off, and has excellent durability and appearance. .
