Description

[Detailed description of the invention] (Industrial application field) This invention is a vehicle seat (especially a car seat) used when attaching an S spring to a seat frame.
This relates to the S spring mounting device.

(Prior technology) Conventionally, when attaching an S spring to a seat frame, the S spring was pulled by hand, and both ends of the S spring were hooked onto both hooks of the seat frame. .

However, as in the conventional method, pulling the S spring by hand and hooking it to the hook requires a considerable amount of force in the fingers and wrist, and if the work is done for a long period of time, it may lead to tendonitis. There is also the problem that the wire diameter of the S spring is limited because the S spring is pulled by human hands, and only wires with a relatively small diameter can be used.

(Problems to be Solved by the Invention) The present invention was devised in view of the problems of the prior art. ,
It can prevent tendonitis in workers' wrists, etc.
Another object of the present invention is to provide an S spring mounting device for a vehicle seat that can use an S spring with a larger wire diameter.

(Means and effects for solving the problem) The S spring mounting device for a vehicle seat according to the present invention conveys the S spring between the hook portions of the seat frame and attaches one end of the S spring to one hook portion. a gripping member to be fitted, a locking portion having a groove for inserting and locking the S spring and rotating in the same plane as the S spring, and a moving portion for moving the locking portion toward the other hook portion. a pressing member made of a magnet that attracts the other end of the S spring and moves it up and down to be latched to the other hook portion of the seat frame; and a locking portion that locks and rotates the S spring. Both ends of the S spring can be automatically hooked and attached between both hooks of the seat frame.

(Embodiment) Hereinafter, one embodiment of the S spring mounting device for a vehicle seat according to the present invention will be described based on FIGS. 1 to 5.

Fig. 1 is a partially cutaway front view showing the state in which the S spring is attached to the seat frame using the device of the present invention. This seat frame is provided with plate-shaped side holding members 3 and 4 that protrude forward from the left and right sides of the seat 2 so as to face each other, respectively. One or more sets of hook parts 5, 6 are formed on mutually opposing surfaces of both side holding members 3, 4 of the seat frame 1. and,
The S spring 8 is conveyed between both hook parts 5 and 6 by a gripping member 7 formed by a small robot or the like,
One end of the S spring 8 is fitted into one hook portion 5.

In the figure, reference numeral 11 denotes a locking part made of a jig with a flat top surface. A U-shaped groove 10 into which one pitch of the S spring 8 is inserted and locked is provided on the top surface of the locking part 11. ,
In addition, it is formed by a protrusion 9 that protrudes linearly from the center thereof.

This locking portion 11 is operated by a servo motor 12.
Rotates in the plane of the spring. 13 in the figure is the locking part 1
The output shaft of the servo motor that rotates 1 is shown.

The above servo motor 12 is mounted on a moving part 15 that moves in the length direction of the S spring 8, and this moving part 1
5 uses a conventionally known movable mechanism such as hydraulic pressure.
This moving part 15 pulls the S spring 8 locked to the locking part 11 in the length direction.

In the figure, reference numeral 16 denotes a locking portion 11 when the S spring 8 is locked in the locking portion 11 and the moving portion 15 pulls the S spring 8 in the length direction against the elasticity of the S spring 8.
This is a spring consisting of a tension spring that prevents the spring from returning.

In the figure, reference numeral 18 denotes a pressing member consisting of a magnet 17 for attracting the other end of the S spring 8, moving it in the vertical direction, and hooking it to the other hook part 8.

Hereinafter, the locking part 11, the moving part 15, the pressing member 18
Explain the operation.

As shown in FIG. 1, the locking part 11 is disposed in advance between the left and right hook parts 5 and 6, with its upper surface at approximately the same height as the left and right hook parts 5 and 6. Therefore, when one end of the S spring 8 is fitted into one of the hook parts 5 by the gripping member 7, a portion of the S spring 8 is inserted into the groove 10 of the locking part 11 and is locked.
Next, as shown in FIG. 2, by operating the servo motor 12, the locking portion 11 is rotated in the direction opposite to the direction of the arrow in FIG. so that it can be easily inserted into the hook part 6.
At that time, the locking portion 1 is
Prevents the return of 1.

After that, the moving part 15 is operated to move the locking part 11 that locks the S spring 8 in the direction of the hook part 6, thereby stretching the S spring 8 and bringing the other end close to the hook part 6. let

Note that when the locking part 11 is rotated with the S spring 8 locked in the locking part 11, depending on the insertion state of the S spring 8 into the locking part 11, as shown in the imaginary line in FIG. The other end of the S spring 8 is bent upward or downward.

Therefore, the magnet 17 of the pressing member 18
Adsorb the other end of the spring 8 and move it up and down,
The height of the other end of the S spring 8 is adjusted to the same position as the height of the hook portion 6.

Next, the servo motor 12 is controlled by the changeover switch.
When the other end of the S-shaped spring 8 is inserted into the hook part 6 by rotating the locking part 11 in the direction of the arrow in FIG. Ru. After hooking the S spring 8 to the hook parts 5 and 6,
Seat frame 1 with S spring 8 stretched from this device
is removed, and the moving part 15 returns the locking part 11 to its original position. Note that FIG. 5 is a perspective view showing the seat frame 1 and S spring 8 assembled according to the present invention.

(Effects of the invention) As described above, according to the S spring mounting device for a vehicle seat of the present invention, the S spring is automatically conveyed between both hook parts by the gripping member, and the S spring is One end can be inserted into one hook part, the S spring can be locked by the locking part of the tension member, and the S spring can be automatically pulled to the other hook part by the moving part, and the S spring can be automatically pulled to the other hook part by the moving part. By rotating the stop part, it can be automatically inserted into the other hook part, and the S
There is no need to tension the spring, and it is possible to prevent injuries such as tendonitis for workers, and the wire diameter of the S spring can also be made thicker.
