Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the mounting structure of a stay holder. To explain in more detail, it is detachably mounted to a holder receiving portion fixed to the seat back frame side of a seat of a vehicle, etc. The present invention relates to a mounting structure for a stay holder.

(Prior Art) A headrest 1 is attached to a seat of a conventional vehicle as shown in FIG. 8, and a headrest stay 1a of the headrest 1 is attached by a stay holder 2. This stay holder 2 has a plurality of protrusions 4 for regulating the height position and a rotation prevention protrusion 5 longer than the protrusions 4 formed on the outer periphery of the lower part of the upper flange part 3, and a jaw 6 protrudes from the lower part. It is set up. It is adapted to be attached to a holder receiving portion 7 fixed to the seat back frame 9. A notch groove 8 is formed in the upper part of the holder receiving part 7, a protrusion 5 for preventing rotation of the stay holder 2 fits into this notch groove 8, and a jaw 6 is latched to the lower end part 7a of the holder receiving part 7. This is intended to prevent the stay holder 2 from rotating and coming off.

(Problems to be Solved by the Invention) However, in the case of the conventional stay holder 2, it is difficult to remove the stay holder 2 after it has been inserted and locked into the holder receiving portion 7. Therefore, if you want to take out the stay holder 2 after assembly, for example, if you want to replace the stay holder 2, or if you want to remove the pad and clean the outer periphery or bottom of the frame, you can remove the back garnish, seat trim, pad, etc. had to be dismantled and cut, making the work extremely complicated.

Therefore, the present applicant has previously proposed a head rest stay holder attachment device (Utility Application No. 59-101600) for detachably attaching a stay holder.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and includes the above-mentioned stay holder mounting structure that is detachably attached to a holder receiving portion fixed to the seat back frame side. A notch groove extending in the circumferential direction is formed in the upper part of the holder receiving part, and a tongue piece is formed in the lower part, and a projection that fits in the notch groove and can rotate in the circumferential direction of the notch groove is formed in the upper part of the stay holder. is formed in a part of the lower part of the stay holder, and the stay holder is normally locked to the lower end of the holder receiving part by the position regulating member. When one end of the stay holder is held inserted inside the tongue at the locked position, and the stay holder is rotated by releasing the restriction of the position regulating member. The holder is characterized in that the jaw is pressed inward by the tongue of the holder receiving portion, and enters the inside of the tongue to be released from the locked state with the holder receiving portion.

(Example) An example of the stay holder mounting structure according to the present invention will be described in detail below with reference to the drawings.

1 to 4 schematically show an embodiment of the present invention, and as shown in FIG. 1, a stay holder 12 is detachably attached to a holder receiving portion 17. That is, as shown in FIG. 2, a cylindrical holder receiving portion 17 is fixed to the upper horizontal rod of the seat back frame 19 by welding or other means. The upper part of this holder receiving part 17 has an approximately
A notched groove 18 is formed in a range of 90 degrees, and a spring member 21 as a position regulating member is attached at a position close to this notched groove 18. Further, a pair of tongue pieces 20 are provided extending from a part of the lower end 17a of the holder receiving part 17.

FIG. 3 shows the stay holder 12,
A headrest stay (not shown) is inserted into the upper part of the stay holder 12, and a stopper part 13 is formed at a predetermined position to restrict vertical movement. A protrusion 1 for regulating the height position is provided at the bottom of this stopper part 13.
4, and a rotation prevention protrusion 1 that is longer than this protrusion 14.
5 is formed, and the rotation prevention protrusion 15 fits into the notch groove 18 of the holder receiving part 17, and is normally attached to one side end 18a of the notch groove 18 by the bias of the spring member 21 as a position regulating member. Being pressed. A pair of jaws 16 are formed at the lower part of the stay holder 12, and the horizontal cross section of the jaws 16 is formed in a crescent shape, and when the spring member 21 is biased, the jaws 16 are engaged with the lower end 17a of the holder receiving part 17. It is located in a position where it is stopped.

Next, the operation of attaching and detaching the stay holder 12 will be explained with reference to FIGS. 4 to 6.

4 and 5 show the state in which the stay holder 12 is attached to the holder receiving part 17, and the lower jaw 16 of the stay holder 12 is locked to the lower end part 17a of the holder receiving part 17, Breaking out is prevented. This state is maintained by the bias of the spring member 21 as a position regulating member.
From this state, when the stay holder 12 is rotated in the direction of arrow a in FIG. It can be moved to the end 18b. When the stay holder 12 rotates approximately 90 degrees, the lower jaw 16 of the stay holder 12 is pressed inside the tongue piece 20 extending on the lower end 17a of the holder receiving part 17, as shown in FIG. The lower end 17 of the holder receiving portion 17 shown by the imaginary line in FIG.
It enters inside the inner peripheral edge 17b of
The locked state between the holder and the holder receiving portion 17 is released, and by pulling up the stay holder 12 in this state, the stay holder 12 can be taken out.

FIG. 7 shows a different embodiment of the present invention. In this embodiment, a frame bracket 31 is fixed to the seat back frame 19, and a holder receiving part 17 is fixed to the frame bracket 31. A holder bracket 32 is fixed to the stay holder 12, and the position of the holder bracket 32 is regulated to the frame bracket 31 by a pin member 33, which replaces the spring member 21 of the above-mentioned embodiment as a position regulating member. Except for this, this embodiment has the same configuration as the embodiment described above. Therefore, pull out the pin member 33 from the frame bracket 31 and attach it to the stay holder 1.
By releasing the rotation restriction of 2 and rotating the stay holder 12 by approximately 90 degrees using the holder bracket 32, the locked state of the jaw 16 with the holder receiving portion 17 is released.

(Effect of the invention) The above is the configuration of an embodiment of the stay holder mounting structure according to the present invention. It is possible to obtain a stay holder mounting structure which can be quickly pulled out and which can reliably prevent the stay holder from coming off under normal conditions, and which is extremely economical.
