Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an undercover mounting structure for a headrest used in a vehicle seat.

[0002]

2. Description of the Related Art Some vehicle seats conventionally provided in vehicles such as automobiles have a headrest provided in a seat back. The above-mentioned headrest is, for example, 4-125 of actual Kaihei.
As is known from Japanese Patent No. 747, the stay covered with a trim cover is embedded with a stay bent in a substantially inverted U shape, and an under cover for treating the end of the trim cover is provided on the lower surface of the pad. The under cover is provided by being inserted through the stay, and the under cover is fixed by fitting a projection into a slit formed in the stay.

As a headrest having another structure, as shown in FIGS. 9 to 11, an inner frame c is provided in a pad b covered with a trim cover a, and an undercover is inserted from the tip side of a stay d. An e frame is fixed to the inner frame c with a fixing tool f such as a screw.

[0004]

However, in the headrest in which the former stay is provided with a slit and the projection of the undercover is engaged with this slit, the strength of the stay is lowered by the slit and the projection is formed on the undercover. Since it has to be formed, there is a problem that it takes time to manufacture.

In the latter case in which the under cover e is fixed to the inner frame c by the fixing tool f, it is necessary to previously provide a screw hole in the inner frame c, and the under cover e is attached by the fixing tool f. Due to its structure, it requires a lot of man-hours for assembling and disassembling work, which is uneconomical.

The present invention has been made in order to solve such a problem, and an object of the invention is to provide an undercover mounting structure for a headrest in which the undercover can be easily assembled and disassembled.

[0007]

In order to achieve the above-mentioned object, the present invention provides an undercover which is provided on a lower surface of the headrest main body, with a locking projection provided near the headrest main body of a stay projecting from the headrest main body. By providing an insertion hole in which small diameter holes are connected to a large diameter hole on both end sides of the, by inserting the stay in these insertion holes, and by sliding the undercover between the headrest body and the engaging protrusion, The undercover is engaged with the engaging protrusion.

[0008]

With the above structure, the undercover can be attached to the headrest body without using fasteners, so that the assembling and disassembling of the undercover can be carried out with a small number of steps.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a headrest, in which reference numeral 1 shows a headrest body. The headrest main body 1 has a pillow-shaped pad 3 covered with a trim cover 2, and the bent portion 4a side of a stay 4 bent in a substantially inverted U shape is embedded in the pad 3.

As shown in FIG. 2, the stay 4 is formed by a round bar or the like, and a large-diameter locking projection 4b is formed slightly on the lower side of the bent portion 4a, and these stays are locked. The left and right stays 4 are connected by a connecting bar 4c on the upper side of the protrusion 4b.

Further, FIG. 3 is provided below the locking projection 4b.
As shown in FIG. 4, a plurality of locking grooves 4d are formed at equal intervals, and the locking grooves 4d are locked to engaging portions of a seat back (not shown), whereby the height of the headrest body 1 can be adjusted arbitrarily. You can do it.

On the other hand, 5 in FIG. 2 is the headrest body 1
Shows an under cover to be attached to the lower surface of the plate, which is formed of a plate material in a rectangular shape, and has keyhole-shaped insertion holes 5a at both ends.

These insertion holes 5a are composed of a small diameter hole 5b into which the stay 4 can be inserted and a large diameter hole 5c into which the locking projection 4a formed on the stay 4 can be inserted so that the small diameter hole 5b faces the same direction. The holes are formed in the under cover 5, and the distance between the small diameter holes 5b and the distance between the large diameter holes 5c are set to be substantially equal to the distance L between the left and right stays 4.

Next, referring to FIGS. 5 and 6, the operation will be described. When mounting the undercover 5 on the lower surface of the headrest body 1, first, as shown in FIG. 5, the insertion hole 5a of the undercover 5 is inserted. The tip end side of the stay 4 is inserted, and the undercover 5 is moved to the headrest body 1 side along the stay 4.

Then, the locking projection 4a of the stay 4 is inserted into the insertion hole 5
After passing from the side of the large diameter hole 5c of a, the under cover 5 is moved laterally to fit the stay 4 into the small diameter hole 5b as shown in FIG. Therefore, the undercover 5 can be easily attached to the headrest body 1.

When disassembling, the under cover 5 can be easily removed by reversing the above operation.

In the above embodiment, the insertion hole 5a of the under cover 5 is formed so that the small diameter hole 5b faces the same direction. However, as shown in FIG. 8, the small diameter hole 5b is formed so as to face each other. May be.

In this case, as shown in FIG. 7, the undercover 5 is curved in an arc shape so that the locking projection 4a passes through the large-diameter hole 5c, and after the passage, the undercover 5 is elastically restored. Since the stay 4 is fitted to 5b,
The locking projection 4a can prevent the under cover 5 from coming off.

In the case of disassembling, the under cover 5 can be easily removed by performing the reverse operation to the above.

[0021]

As described in detail above, according to the present invention, the stay protruding from the headrest body is provided with the locking projection, and the undercover is provided with the insertion hole formed by connecting the large diameter hole and the small diameter hole.
After inserting the stay into the insertion hole of the under cover, the under cover is locked by the locking projection,
The under cover can be attached without using fasteners.

Also, since the undercover can be easily removed, the man-hours required for mounting and disassembling the undercover can be greatly reduced as compared with those using a conventional fastener, and it is not necessary to provide a slit in the stay. ,
Problems such as a decrease in the strength of the stay do not occur.

Further, since the undercover need not be preliminarily provided with projections or the inner frame is not required to be provided with screw holes, the manufacturing is easy.
