Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a guide for a headrest in an automobile seat.

(Prior art) The headrest guide is fixed to the upper part of the seat back, the headrest stays are inserted, and pins are hooked into notches formed at appropriate intervals in the vertical direction, thereby raising the headrest to a predetermined height. It is a structure that maintains

This will be explained with reference to FIGS. 6 and 7.

The guide body shown at 2' in the figure has a square flange 2'a.
A cylindrical portion 2'b is integrally formed in the guide body 2', and a mounting hole 2'c into which the stay 7 is fitted is provided in the center thereof, and a hollow flange 2'a is formed in the flange 2'a of the guide body 2'. A storage part 2'd is provided, and a shaft 2'e is provided at the back of this storage part 2'd, and approximately J is attached to the shaft 2'e.
Attach the letter-shaped pin 3' to the stay 7.
It is biased so that it fits into the notch 7a. A knob 4' is provided at the tip of the pin 3',
By sliding the knob 4' in the direction of the arrow, the pin 3' is separated from the notch 7a and the lock is released.

Since the fit between the stay 7 and the through hole 2'e is very tight in order to prevent noise generation, a large force is required to pull out the stay.

This employee headrest guide has the following defects.

When changing the height of the headrest, especially when pulling out the headrest for a fully flat seat, one person should slide and hold the headrest knob while another person changes the height of the headrest. or have to be pulled out. Therefore, the above-mentioned operation could not be performed without the presence of two people, resulting in extremely poor operability.

(Purpose of the invention) The present invention was made in view of the above-mentioned conventional circumstances, and its purpose is to enable one person to adjust the height of the headrest and pull it out.

(Structure of the invention) The headrest guide according to the invention is characterized in that the knob and the guide body are each formed with a holding part that fits into each other and holds the pin in a state separated from the notch. .

(Example) An example of the present invention will be described with reference to FIGS. 1 to 5.

A pair of head rest guides 1, 1 according to the present invention are arranged on the upper part of the seat bag 9, and the stays 7, 1 of the head rest 8 are attached to each head rest guide 1, 1.
7 is inserted (Fig. 1, Fig. 2).

The guide 1 is composed of a guide body 2, a pin 3, and a knob 4, as shown in FIGS. 3 and 4.

The guide body 2 described above has a rectangular plate-like flange 2a.
A cylindrical portion 2b is integrally formed in the lower part of the cylindrical portion 2b, and a through hole 2c into which the stay 7 is fitted is bored in the center thereof. Then, one side of the through hole 2c is made hollow, and a shaft 2e is disposed at the back of the storage portion 2d, and a pin 3 is attached to the shaft 2e.

Further, the pin 3 is an elastic core material having a substantially J-shape,
Due to its elasticity, the pin 3 is urged toward the stay 7 so as to engage with the notch 7a of the stay 7.
A knob 4 is provided at the tip of this pin 3.

Furthermore, the knob 4 has a semicircular shape with anti-slip irregularities on the outside, and is pushed with a finger or the like to move in the direction of the arrow in the figure to release the pin 3 from the notch 7a.

A concave holding part 6 as shown in FIG.
Furthermore, a convex holding portion 5 that engages with the holding portion 6 is formed on the upper part of the knob 4.

Therefore, as shown in FIG. 5, when the pin 3 moves away from the notch 7a, the holding parts 5 and 6 fit into each other and maintain the separated state (unlocked state).
Moreover, when the notch 7a is to be hooked again with the pin 3, the knob 4 is turned in the direction of the stay 7 and the holding parts 5 and 6 are separated.

The guide body 2 and the knob 4 are made of synthetic resin having appropriate flexibility so that the holding parts 5 and 6 can be smoothly fitted and removed.

In this embodiment, when the height of the headrest 8 is adjusted or removed, the knob 4 is slid to fit the holding parts 5 and 6 together. When the knob 4 is slid in the opposite direction after the height adjustment etc. are completed, the pin 3 is once again engaged in the notch 7a and is in a locked state.

In the embodiment, the guide body 2 is formed with a concave holding part 6, and the knob 4 is formed with a convex holding part 5, but this may be reversed as desired.

(Effects) As described above, the present invention is a guide for a headrest in which a pin for engaging a notch in the stay is provided on the guide body that fits into the stay of the headrest, and a knob for moving the pin away from the notch is provided on the pin. In the head rest guide, the knob and the guide body are each formed with a holding part that fits into each other and holds the pin in a state in which it is moved away from the notch. state).

Therefore, the height of the headrest can be adjusted and the headrest can be pulled out by one person, and the operability can be improved.

By doing so, we will reach our intended purpose.
