Abstract

In manufacturing a head rest mounted on the upper back of a conventional car seat backrest, the worker has to hand-wrap the work by hand covering the outer shell of the headrest body made of elastic material such as urethane foam. Therefore, it takes a long time and has a problem that it is difficult to provide a uniform shape of the headrest is to devise a device for devising the envelope wrapping device of the headrest body of the car seat to be able to perform mechanical winding work quickly and accurately.

Description

The apparatus for covering of the body Headrest of automobile seat

The present invention is a device for a headrest that is separately mounted on the top of a car seat such as a passenger car to support the head comfortably when the driver or passenger takes a rest, and more specifically, a device configuration for mechanically winding the outer shell of the headrest. In general, the headrest includes a tilting device and a fixing device in which the headrest can be tilted at an angle, and is filled with a cushioning material (such as a polyurethane foam) that surrounds the tilting and fixing device all around. The head rest is manufactured by forming the body of the rest and winding the outer surface of the body with a beautiful outer shell. The winding of the outer shell on the head restraint body has been performed by a worker by hand.

As the conventional work to wrap the outer shell on the headrest body by hand, the work efficiency is low, there is a problem such as skill required to manufacture a uniform headrest.

The present invention is designed to provide a headrest uniform in shape because the mechanical winding operation is performed without the manual winding operation as described above, as described above based on the accompanying drawings.

In constructing the outer shell wrapping device (1) of the head restraint body (H) according to the present invention, the cylinder rod (4) vertically moves the upper and lower operation cylinder (3) in the upper center of the horizontal frame (2) of a constant size Two fixing holders 6 of permanent magnets and clips, which are mounted downwardly and permanently fix the left and right stay bars 5 and 5a of the headrest H to the end of the cylinder rod 4 ( 6a), and the fixed holders 6 and 6a are mounted on the bottom of the support plate 7 by means of a fixed holder support plate 7 protruded from the end of the cylinder rod 4, and the support plate 7 is provided with two auxiliary plates. Two cylinders 3a and 3b are horizontally mounted on the left and right posts 9 and 9a of the frame 2, respectively, and supported by the rods 4a of the cylinder 3a. ) And the rod 4b of the cylinder 3b are mounted on the 'L' type brackets 10 and 10a mounted on the left and right posts 9 and 9a of the frame 2 symmetrically into the frame 2. Being cylinder At the tip of each of the rods 4a and 4b of (3a) and (3b), the braces 11 and 11a made of circular arcs are extended, and the rods 4a and 4b are positioned below the braces 11 and 11a. The auxiliary support sections 8b and 8c are supported so that the left and right movements of the pressing strips 11 and 11a are precisely performed according to the appearance, and the headrest is disposed at the lower center between the pressing strips 11 and 11a. The elliptical frame 12, which is somewhat smaller than the size of the body H, is mounted on the left and right posts 9 and 9a of the ellipsoidal frame 12 and the left and right fixed sections 13 and 13a of the frame 2. The outer shell winding apparatus 1 of the headrest body implemented by this invention is comprised.

Before the operation of the device configured as described above, the headrest pad and the frame are installed in the fixed holders 6 and 6a mounted on the tip of the cylinder rod 4 of the cylinder 3 in advance, and the pad and the frame are charged. Insert the left and right metal staybars 5 and 5a of the headrest made of a foamed urethane foam such as the headrest body H in close contact with each other. 6a) is made of a magnet having a relatively strong magnetic force, and the suction bars 11 and 11a of the side cylinders 3a and 3b are sucked and fixed by the attraction force of the magnetic force. The volume of the frame is reduced and the attached part of the outer shell 14 having the upper and left and right sides sewn on the periphery of the ellipsoid 12 and the lower side open to the ellipsoid 12 about half as shown in FIG. 2. The open part is turned over to the outer periphery of the ellipse frame (12) and the ellipse frame ( 12, the rods 4, 4a and 4b of the cylinder 3 and the cylinders 3a and 3b are drawn out horizontally from the vertical down side and the left and right side, respectively. When the braces 11 and 11a squeezed to the ends of the cylinder rods 4a and 4b are pressed against the headrest body H from left and right, the body H having elasticity is elastically contracted so that the body is elastically shrunk. At the same time as the size of the open portion of 14) is reduced and the rod 4 of the cylinder 3 is pulled downward from the top to press the headrest body (H) downward, the body (H) is open of the outer shell (14) The headrest body is inserted into the outer shell 14 and inserted into the outer shell front end while the open part of the outer shell inverted to the periphery of the ellipse frame 12 is wound in its original position and the entire headrest body H is wound. Passes through the inside of the ellipse frame (12) is the body (H) is reduced to its original size burnt the shell It becomes the state located under the ellipsoid 12 in the state which made it forcefully swollen.

Since the stay bar (5) (5a) of the head restrained outer shell located below the ellipse (12) through the ellipse (12) as described above is forcibly pulled out from the fixing holder (6) (6a) In this way, the outer cover of the headrest body can be mechanically fastened and produced in a uniform form.

Claims (1)
