JPS5920127Y2 - Seat headrest insertion structure - Google Patents

Description

[Detailed Description of the Invention] The object of this invention is to provide an insertion part structure that makes it easy to insert the headrest of a car seat back and also allows reliable insertion.

As shown in FIG. 5, the conventional structure of the insertion part of the headrest of a seat back is such that the upper part of the holder 1 is flat and the movement of the seat back pad 2 is not particularly restricted.

Therefore, the position of the hole 3 of the seat back pad 2 and the headrest insertion port 4 of the holder 1 may be misaligned, and the stay 6 of the headrest 5 may be inserted incorrectly as shown in FIG.

7 is a bracket for fixing the holder 1.

Alternatively, there is a method of inserting a guide 9 in advance as shown in FIG. 8, but when the seat is folded down and used as a bed, a lumpy feeling remains even if the headrest 5 is removed.

Furthermore, if a large load is applied, there is a risk that the guide 9 will be damaged.

This invention eliminates the above-mentioned known drawbacks.

This invention will be explained as follows with regard to the embodiment shown in the drawings.

11 is a seat back, 12 is a headrest, and a hole 14 is provided at the top of the seat back 11 into which a stay 12a of the headrest 12 extending below the seat back pad 13 is inserted.

Further, a bracket 16 made of iron plate or the like and formed by press is fixed to the seat back frame 15 made of iron plate or the like by spot welding or the like.
・Insertion holes 17.17 for the headrest stay insertion holder 18 are formed on the upper and lower sides of 16, and the insertion holes 17.1
The bracket 16 is formed such that the bracket 7 is located in the hole 14.

The headrest stay insertion holder 18 is provided with a cylindrical flange 19 at the headrest insertion opening 20 at its upper part.

The flange 19 is integral with the holder 18 and formed at the same time as the holder.

A check claw portion 21 is provided at the bottom of the holder 18.

The headrest stay insertion halter 18 configured as described above is attached to the bracket 16 of the seat back frame 15.
is inserted into the insertion hole 17.17, and is made non-removable by the non-return claw 21, and the cylindrical flange 19 is fitted with the seat back pad 13 at the lower edge of the hole 14.

Thus, the hole 14 of the seat back pad 13 is fitted into the cylindrical flange 19 of the headrest stay insertion holder 18 and does not move easily.

Further, when assembling the seat, since the seat back pad is covered from the direction of arrow A, the hole can be easily fitted into the cylindrical flange, and the pad can be positioned at the same time.

22 is the epidermis. In summary, in this invention, the hole in the seat back pad and the headrest insertion port of the holder always match, so the stay of the headrest can be inserted easily and reliably.

Furthermore, the seat back butt can be easily positioned when assembling the seat.
