Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a vehicle seat that uses a wire frame, such as an automobile seat, and is characterized by a retracting structure of the end of the seat cover relative to the wire frame.

(Prior art) A vehicle seat in which a pad material mounted and supported on a wire frame is covered with a seat cover, and the end of the seat cover is drawn in and locked to the periphery of the wire frame with a hog ring, is disclosed in Utility Model Application No. 60-158496. As seen in the official publication, it is widely used in automobile rear seats where strength is not particularly required, but the conventional seat cover for this type of vehicle has a hog ring that pulls the end of the seat cover into the wire frame and locks it. Since the sheet is pulled in locally, wrinkles occur in some areas, resulting in poor quality and poor workability. As seen in Japanese Utility Model Application Publication No. 61-63997, a solution to this problem is that a locking hook is provided at the end of the seat cover, and this locking hook is connected to the peripheral edge of the wire frame. A locking device has also been proposed, but since the locking terminal is exposed at the bottom, the locking terminal may come into contact with other objects during transportation or installation on the vehicle body, interfering with work. There are various inconveniences such as the locking being released in some cases. Also, Utility Model Application No. 57-37356 discloses a device in which an insertion piece is attached to the end of the seat cover and inserted into a recess made in the bottom of the pad material to prevent the end from touching other objects. As seen in the publications, the recesses formed in the bottom of the pad material were insufficient in strength and could not be used for a long period of time.

(Problems to be solved by the invention) The problem to be solved by the invention is to solve the above-mentioned problems so that the locking terminal is not exposed at the bottom, and has sufficient strength and long-term durability. ,
Moreover, the object is to provide an inexpensive vehicle seat that has a good finish, is of excellent quality, and has good workability.

(Means for solving the problem) The vehicle seat that solved the above problems is
In a vehicle seat in which a seat cover is covered with a pad material that is mounted and supported on a wire frame, and the end of the seat cover is pulled in and locked to the periphery of the wire frame, a band plate for locking the end of the seat cover is attached. At the same time, a locking portion having a substantially U-shaped cross section is formed on the wire frame side to engage the insertion end, and the locking portion is bent upward, and this locking portion is formed on the bottom surface of the pad material. It is characterized by intervening in a provided recess, and engaging and holding the insertion end with a locking portion within the recess.

(Function) Such a vehicle seat is installed and used within a vehicle body in the same manner as conventional vehicle seats of this type that use a wire frame as a base.

(Example) Next, the present invention will be described in detail using the illustrated rear seat for an automobile as an example.

In the first and second embodiments shown in FIGS. 1 and 2, 1 is a wire frame in which a vertical wire 1a and a horizontal wire 1b are combined and connected, and the edge portion of the vertical wire 1a is It is formed in a substantially U-shaped locking part 2 bent upward, and also has a plurality of vertical wires 1 as shown in the second embodiment shown in FIG.
If the mutual spacing between a and a is too wide, a retainer 3 having a substantially U-shaped cross section and having connecting portions 3a, 3a to the horizontal wires 1b, 1b at both free ends is used between each locking portion 2 to connect the retainer 3. The use parts 3a, 3a are provided in a state where they are locked to the horizontal wires 1b, 1b. Reference numeral 4 denotes a pad material mounted and supported on the wire frame 1. The pad material 4 is made of a flexible plastic foam such as polyurethane foam, and the locking portion 2 of the wire frame 1 is attached to the bottom surface of the pad material 4. A recess 5 necessary for intervention is provided. Reference numeral 6 denotes a seat cover that is covered with a pad material 4 mounted and supported on the wire frame 1, and the seat cover 6 is made of synthetic resin leather material, fabric material, leather, etc. and is sewn into a bag shape. A narrow locking band plate 7 made of vinyl chloride resin, polypropylene resin, etc. is attached to the terminal corresponding to the lower opening by sewing or welding, and this part is inserted with some elasticity. It is formed at the end portion 8. Note that the insertion ends 8 may be formed on each of the four side edges of the lower end opening of the seat cover 6, but if the seat cover 6 is elongated, they may be formed only on two side edges in the longitudinal direction. Also, the locking band plate 7
One piece may be used for each insertion end 8, or it may be divided into a plurality of pieces.

When the seat constructed in this manner is installed inside the vehicle body, as with conventional vehicle seats of this type that use a wire frame as a base, the end of the seat cover 6 is attached to the locking band plate 7. The insertion end 8 is formed upward at a required side edge of the wire frame 1 and inserted into the recess 5 on the bottom surface of the pad material 4. Since it is pulled in and fixed by engaging and holding the locking part 2 in the shape, a good-looking finish is obtained without the occurrence of fine wrinkles that can be seen in the case of partial pulling in with a hog ring. It is extremely easy to work since it is only necessary to bend the insertion end 8 to which the locking band plate 7 is attached by more than 90 degrees from its base and forcibly engage it with the locking part 2 of the wire frame 1. . Moreover, since the locking portions 2 having a generally U-shaped cross section and which are formed upward on the required side edges of the wire frame 1 are inserted into the recesses 5 on the bottom surface of the pad material 4, this locking portion 2 and the insertion end 8 engaged with it are not exposed to the outside, which not only improves appearance, but also prevents them from being damaged or unlatched due to contact with other objects, and is also strong. Not only is it sufficient and can be used for a long time, it has a good finish and is of excellent quality.

(Effects of the invention) As is clear from the above description, the present invention uses the end of the seat cover as an insertion end to which a locking strip is attached, and the edge of the wire frame has a substantially U-shaped cross section. A good-looking finish can be obtained with a simple structure in which the locking portion is formed upward, the locking portion is inserted into the recess in the lower part of the pad material, and the insertion end is engaged with the recess. Not only is it easy to install and remove, making it easy to work, but the locking terminal consisting of the locking part and the insertion end is not exposed to the outside.
It is possible to provide a vehicle seat that has a good appearance, is not damaged or unlatched by touching other objects, has sufficient strength, can be used for a long period of time, has a good finish, and is excellent in quality.

Therefore, the present invention solves the problems of conventional seats for vehicles of this type, and has the advantage of being mass-produced at low cost due to the small number of parts and work processes, and has extremely great practical value.
