[Industrial applications]

 The present invention relates to a back cover mounting structure for a vehicle rear seat.

In a rear seat for a vehicle, a back cover 4 is attached to a rear portion of a seat back 1 which can be tilted forward as shown in FIG. is there.

Conventionally, the back cover 4 reinforces the part where the hands are put in and out in accordance with the operation of tilting the seat back forward, and as shown in FIG. 6, the back plate 3 on which the top of the cushion pad 5 is placed is omitted. The receiving portion 3a bent inwardly in a V shape is wound up to the stopper portion 3c below the inclined portion 3b, so that the seat back 1 is pulled and fixed to the back surface of the back plate 3 from the top side. It is attached to cover the end of the seat cover 6. To attach the back cover 4 to the back plate 3, the clip 7 inserted near the lower part of the plate surface of the back cover 4 is fixed to the back plate 3 by a shaft and fixed to the back plate 3, and the back cover 3 faces the slope 3b. The upper cover plate surface of the back cover 4 is tightened and fixed to the back plate 3 with a tapping screw 8 inserted through the seat skin 6.

However, in this back cover mounting structure, since the back cover 4 is completely abutted and fixed to the back plate 3 via the seat skin 6, the degree of tension and fastening of the seat skin 6 varies. It is difficult to avoid, and even if the shape of the top of the seat back is properly maintained before mounting, it is easy to cause the shape of the top of the seat back to be deformed by forcibly pulling the seat skin. In particular, when a moquette or soft weave cloth material is used as the seat skin 6, the seat skin lacks in ductility, so that extreme staking may be given to the top of the seat back.

In order to prevent the shape of the top of the seat back from collapsing, the attachment state of the back cover 4 may be adjusted in accordance with the degree of tension and attachment of the seat cover 6. However, when the tapping screw 8 is used, the degree of tightening with respect to the back plate 3 is adjusted by adjusting it in the loosening direction, which is not preferable because it is difficult to adjust and it takes man-hours.

[Problems to be solved by the device]

 The present invention can easily adjust the facing distance of the back cover with respect to the back plate according to the degree of tension and attachment of the seat skin, and can securely fix the back cover to the back plate. It is an object to provide a mounting structure.

[0007]

[Means for Solving the Problems]

 In the mounting structure of the back cover for the vehicle rear seat according to the present invention, the protrusion is provided by rising from the plate surface of the back cover which is positioned relative to the inclined portion of the back plate, and the protrusion is inserted through the seat skin. A mating stop hole is provided on the slope of the back plate, and the engaging surface with which the protrusion comes into elastic contact with the hole edge of the stop hole is formed as a multi-stepped surface. By elastically abutting against the hole edge of the stop hole to set the facing interval of the back cover with respect to the back plate, and by attaching and fixing the back cover to the back plate together with the shaft stopper with the projection 10. ..

[0008]

[Action]

 In this back cover mounting structure for a vehicle rear seat, the selected step portion of the protrusion is elastically brought into contact with the hole edge of the stop hole to elastically abut the back cover to the back plate in accordance with the degree of tension and stop of the seat cover. Since the relative distance can be set, even if there are variations in the degree of tension and fastening of the seat skin, it is possible to avoid forcibly pulling the seat skin and prevent the top of the seat back from deforming. Also, since the back cover is elastically abutted against the hole edge of the stop hole, the back cover is fixed to the back plate together with the shaft stopper by the protrusion, so be sure to attach it securely so that it does not come off even if it is subjected to vibrations such as traveling. Can be fixed.

【Example】

 FIG. 1 is a seat back of a vehicle rear seat similar to that shown in FIG. 5, and has the same structure as the upper side of the seat back 1 shown in FIG. In the figure, the same components as those shown in FIG. 6 are designated by the same reference numerals.

In its constituent parts, the back plate 3 has a slope part 3b bent inward from a receiving part 3a of a cushion pad 5 which is bent and formed in a substantially V-shape similar to the conventional example. The slope 3b is provided with a stop hole 9 into which a protrusion to be described later is inserted and engaged.

The back cover 4 is formed in a substantially V shape having an inclined plate surface facing the inclined surface portion 3 b of the back plate 3, and is raised from the inclined plate surface and inserted into the stopper hole 9 of the back plate 3. A mating protrusion 10 is formed. As shown in FIG. 2, the protrusion 10 is formed by bending the tip side 10a toward the retaining hole 9 of the back plate 3 into a substantially V shape, and the apex thereof is slightly above the upper hole edge of the retaining hole 9. It is formed so as to be elastically pressed in the engagement state with the stop hole 9 by being located at. The projecting portion 10 serves as an engaging surface where the upper slope of the base side 10b elastically abuts the hole edge with the stop hole 9, and the upper slope near the base is used as one step 10c. A plurality of step portions are formed by notching at least one step portion 10e of the above in the slope near the top. It should be noted that the clip 7 can be integrally formed on the back cover 4 by projecting from the lower plate surface similarly to the projecting portion 10.

On the back plate 3 to which this back cover is attached, the seat skin 6 is wound from the top side on which the top part of the cushion pad 5 is placed to the back surface side of the back plate 3 through the slope 3 b of the back plate 3. The seat portion is pre-assembled by fixing the end portion of the above to the stopper portion 3c below the inclined surface portion 3b with a stopper 11 such as a c-shaped ring. With respect to the back plate 3, the clip 7 of the back cover 4 is press-fitted into the fitting hole 3d provided in the back plate 3, and the protrusion 10 of the back cover 4 is attached to the seat surface 6 as shown in FIG. The back cover 4 can be attached by press-fitting it into the stop hole 9 of the back plate 3 through the provided through hole 6a.

In this press-fitted state, if the degree of pulling and fastening of the seat skin 6 is proper, the stepped portion 10c near the base of the protrusion 10 is elastically engaged with the hole edge of the stop hole 9 as shown in FIG. With this, the back cover 4 can be securely attached and fixed to the back plate 3 together with the shaft stop by the clip 7.

On the other hand, when the seat skin 6 is pulled excessively, the protrusion 10 is press-fitted so that the step 10 c provided near the tip of the protrusion 10 is engaged with the hole edge of the stop hole 9. Lower the degree. In the press-fitted state, a gap w is provided between the back plate 3 and the back cover 4 so that no finger can be inserted, and the degree of pressing down the seat cover 6 can be relaxed. In addition, the back cover 4 can be firmly attached and fixed to the back plate 3 by elastically engaging the protrusion 10 with the hole edge of the stop hole 9 as described above. With this projection 10, even if there is a variation in the shape of the back plate 3 or the opening position of the stopper hole 9, it is possible to deal with the variation in a similar manner.

[0015]

[Effect of the device]

 As described above, according to the back cover and the mounting structure of the vehicle seat back according to the present invention, the relative distance is adjusted by the protrusions in accordance with the degree of tension and attachment of the seat cover, so that the back cover is attached to the back plate. Since the shape of the top of the seat back can be prevented from being deformed, the back cover can be securely and easily attached and fixed to the back plate.
