Description

[Detailed Description of the Invention] <<Technical Field of the Invention>> This invention relates to an improvement of a headrest holder.

<<Prior Art and its Problems>> Generally, a headrest is fixed to the upper part of the seat back of a vehicle seat. The headrest has a pair of shafts protruding from the lower part of the headrest body, and the headrest body is fixed by inserting the shafts into a headrest holder attached to the upper part of the seat bag.

FIG. 3 shows the configuration of a conventional headrest part. The seatback consists of a seatback frame 1, a holder bracket 2 fixed to the upper part of the seatback frame 1 by welding, etc., and a pad 3 that covers the outer periphery of the frame 1. The headrest holder 5 is inserted into the holder bracket 2 through a through hole opened in the covering material 4 and the pad 3, and the headrest holder 5 is inserted into the inner cylindrical portion of the headrest holder 5. 6 is inserted through the shaft 7, and the headrest 6 is stably fixed.

By the way, the head rest holder 5 is attached to the covering material 4.
A through hole 4a for inserting the shaft portion of the holder 5 is opened, and the periphery of the through hole 4a is covered with a flange portion 5a protruding from the top of the holder 5. When you lean back, the upholstery 4 is pulled downward as shown by the arrow P in FIG. Because it is visible,
At the same time, since the opposite side is stretched, wrinkles are generated in the vicinity of the flange portion 5a, resulting in an unsightly appearance.

《Purpose of the invention》 This invention completely prevents the movement of the hole position due to the above-mentioned dragging phenomenon. The purpose is to improve appearance.

<<Structure of the invention>> In order to achieve the above object, this invention includes a headrest holder main body that is inserted and fixed into a holder bracket provided on the seat bag, and a headrest holder that fits into the upper projecting end of the main body and is located on the periphery of the projecting end. It is characterized by comprising a cover whose periphery is welded to the surface of the covering material.

<<Description of Embodiments>> FIG. 1 is an exploded perspective view of a headrest holder according to the present invention, and FIG. 2 is a sectional view of essential parts showing the headrest holder fixed to a seat bag.

In the figure, the configuration other than the headrest holder is the same as the conventional one, so the same parts will be described with the same reference numerals.

In the figure, this headrest holder 10 is
The headrest holder main body 101 is inserted into the holder bracket 2 and has a flange 101a on the top that projects above the seat bag, and the cover 102 is fitted and fixed to the flange 101a. Headrest body 101
The tip of the flange 101a is a tapered locking pawl 101b, and a positioning protrusion 101c that fits into a positioning groove 2a formed in the holder bracket 2 is formed at the bottom of the flange 101a.

The flange 101a has a substantially rectangular shape, and locking windows 101d are formed on its front and rear surfaces.

The cover 102 is fitted to the outer circumferential portion of the flange 101a, and has an opening 102a formed in the upper surface of its central portion for fitting the headrest shaft, and has an opening 102a formed inside to fit into the locking window 101d. A pair of locking protrusions 102b that fit together are formed. A flange portion 102 is provided on the periphery of the lower surface of the cover 102 in contact with the periphery of the opening of the covering material 4.
c is integrally formed.

Therefore, as shown in FIG. 2, when the headrest holder is attached to the seat bag, the locking protrusion 102b of the cover 102 is attached to the flange 101.
The cover 102 is elastically fitted into the locking window a, and the peripheral flange 102c of the cover 102 is in contact with the covering material 4.

In this state, the cover 102 is integrated with the covering material 4 by welding the flange portion 102c to the covering material 4 using ultrasonic waves or other heating means. In addition, the peripheral flange portion 102c of the cover 102 is welded to the covering material 4 in advance, and the cover 1
The locking protrusion 102b of 02 may be fitted into the locking window of the flange 101a.

<Effects of the invention> As explained in the examples above, this invention has the following effects:
Since the cover that fits onto the top of the headrest holder body is integrated with the upholstery, a certain amount of tension is applied to the upholstery, so even if it is dragged, the upholstery will not shift at this part. A good appearance is maintained without wrinkles.
