Abstract

(57) [Summary] (with amendments) [Purpose] For example, in the hinge portion of a reclining seat, to easily and reliably prevent the hinge from coming off from the rotating shaft. [Configuration] Hinge (4) on the rotating shaft (2) extending from the base (1)
Fit the shaft hole (5) of the hinge (4) into the cover from below.
At the same time as the cover (7) is attached, the fixing fitting (6) built into the cover (7) is fitted into the circumferential groove (3) of the rotating shaft (2) to prevent it from coming off.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a hinge mounting mechanism applied to reclining seats, for example. It is.

0002

[Conventional technology]

Conventionally, for example, in the hinge part of a reclining seat, as shown in Fig. 5, Hold out the rotating shaft (2) A with the circumferential groove (3) A formed at the tip from the base (1) A, and insert it into the rotating shaft (2) A. Fit the shaft hole (5)A of the hinge (4)A, and fit the E-ring (6)A into the circumferential groove (3)A of the rotating shaft (2)A. After attaching the hinge (4)A to prevent it from coming out, cover the cover (7)A from below the hinge (4)A. The configured configuration was applied.

0003

[Problem that the idea aims to solve]

In the conventional hinge part mentioned above, the E-ring (6) A is small and difficult to hold directly by hand, so As shown in 6, it was supported by jig (8) A and fitted into the circumferential groove (3) A of rotating shaft (2) A, but the jig (8) The E-ring (6)A is misaligned on the tool (8)A, and the E-ring (6)A is attached to the rotating shaft (2)A as shown in Figure 7. The problem is that the E-ring (6)A falls off after it is fitted out of the circumferential groove (3)A. There was a point.

0004

[Means to solve the problem]

The present invention was developed as a means to solve the above-mentioned conventional problems. A circumferential groove (3) is formed at the tip of the rotating shaft (2), and the shaft hole of the hinge (4) is formed in the rotating shaft (2). (5) and a cover (7) is attached from below the hinge (4). The cover (7) has a built-in fastening fitting (6) that fits into the circumferential groove (3) of the rotating shaft (2). A hinge attachment mechanism is provided.

[0005]

[Effect]

Fit the shaft hole (5) of the hinge (4) onto the rotation shaft (2) of the base (1). and the hinge (4) When the cover (7) is attached from below, the clasp built into the cover (7) The tool (6) is fitted into the circumferential groove (3) of the rotating shaft (2) to prevent the hinge (4) from coming off. .

[0006]

【Example】

If the present invention is explained by an embodiment shown in FIGS. 1 to 4, (1) is the base; In the case of the hinge part of a reclining seat, the base (1) is the side of the seat cushion. installed on. A rotating shaft (2) is extended from the base (1), and the rotating shaft (2) is A circumferential groove (3) is formed at the tip. (4) is a hinge, and the lower end has a shaft hole (5 ) is formed, and the rotation shaft (2) of the base (1) is located in the shaft hole (5) of the hinge (4). It is fitted.

[0007] (7) is a cover, which has a U-shaped fastening fitting with a fitting groove (61) as shown in Figure 2. (6) is built-in, and a shaft groove (71) is formed inside the cover (7). So Then, attach the cover (7) to the hinge (4) from below. At this time, the shaft of the cover (7) The rotation shaft (2) of the base (1) fits into the groove (71), and the rotation shaft (2) of the base (1) is inserted into the cover (7). The peripheral edge of the fitting groove (61) of the fastening metal fitting (6) fitted into the circumferential groove (3) of the rotating shaft (2), In this way, the hinge (4) is not only prevented from coming off, but also attached to the rotation axis (2) of the base (1). Rotatably mounted.

[0008] The cover (7) is made of plastic or rubber, for example by replacing the fastening fittings (6). Manufactured by injection molding using a pre-inserted mold.

[0009]

[Effect of the idea]

Therefore, in this invention, the cover is attached to the hinge and at the same time it is attached to the hinge rotation axis. It is designed to prevent it from coming off, eliminating the need to install the E-ring separately from the cover using a jig. This also prevents the fastening metal from coming off the circumferential groove of the rotating shaft and falling off.
