Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external mounting mechanism for a backrest of a vehicle, particularly including a backrest supporting member provided with a mounting arm.

[0002]

[Prior art]

Known backrests in vehicles are preferably foldable, if possible, but this is often done in a rotating motion, in which a suitable rotating rod rotates in an opening. They require considerable installation effort for installation and removal.

[0003]

[Problems to be solved by the invention]

An object of the present invention is to develop an external mounting mechanism in which the mounting operation of the above-mentioned type of mounting mechanism is significantly simplified, and the folding can be performed without any special labor.

[0004]

[Means for Solving the Problems]

The above object is achieved by connecting the mounting arm and the support member with a rest connection.

[0005] According to the rest coupling, the mounting arms are connected without requiring any extra mounting operation.

[0006] Preferably, the dormant connection is self-suppressing and is not easily released. In a preferred embodiment, it is configured such that it can be achieved without using an extra tool simply by utilizing the rotation of the locking pawl described later.

[0007] The support member includes a receiving portion for the connecting member on the mounting arm. In a preferred embodiment, the connecting member is configured as a connecting rod, which is held on the mounting arm by a bearing fork member. The connecting rod is oriented horizontally with respect to the support member and can be provided in a receiving portion attached to the support member. For example, the receiving part comprises two spaced receiving slits connected to a receiving fork,
This slit is formed in the side of the receiving fork. This receiving fork can be formed by bending from the support member since the manufacture of the support member is simplified.

The bearing fork member and the connecting rod are introduced between the receiving forks, whereby the connecting rod is slid into the receiving slit. This means that the fork connecting plates are introduced into each other.

In order to ensure the resting connection, the resting connection has a locking pawl, and the locking pawl is rotatably mounted on the support member. The locking pawl has a locking slit. This locking slit has a self-contained connecting contour in the area of the receiving slit. Preferably, the locking pawl is arranged in both receiving slits, but since the connecting rod should protrude beyond the receiving slit, the hook of the locking pawl is provided externally so as to be able to hold the connecting rod. It is also possible.

[0010] Since the locking pawl abuts the back wall of the receiving fork at the end position, an elastic member is provided to hold the locking pawl in this position. This resilient force and the contour design of the connecting contour ensure a play-free function and eliminate the self-release of the locking pawl. As long as the mounting arm and the supporting member are connected, the locking pawl is released only when the pressure of the connecting rod acts.

Note that, within the scope of the present invention, a configuration may be adopted in which the receiving fork and the locking pawl are provided on the mounting arm, and the connecting rod and the bearing fork member are provided on the support member.

BEST MODE FOR CARRYING OUT THE INVENTION

Other advantages, features and uniqueness of the present invention will be described below based on preferred embodiments and drawings.

FIG. 1 is a front view of an external mounting mechanism according to the present invention, FIG. 2 is a side view of the external mounting mechanism of FIG. 1, and FIGS. 3A to 3D are perspective views showing steps of assembling the external mounting mechanism. It is.

An external mounting mechanism according to the present invention includes a mounting arm 1 and a support member 2 as shown in FIGS. Preferably, the mounting arm 1 is fixed to the backrest of the vehicle, for example to the backseat, while the support member 2 is installed on the chassis. The support member 2 has an installation plate 3 formed in an angle shape and having a through hole 4 for installation from the chassis, for example, to the chassis.

A holding plate 5 stands upright from the mounting plate 3, from which a receiving fork 6, which is best seen in FIG. The receiving fork 6 has two receiving slits 7 spaced apart, and only one slit can be recognized in the drawing. The other slit is located at the rear of the locking pawl 8 and is connected to the holding plate 5 via the rotating shaft 9.

The locking pawl 8 is formed in the shape of a tongue and, in the end position, the rear wall 10 of the receiving fork 6
Abut. In this position, the locking pawl 8 is held by the elastic member 11. One end of the elastic member 11 is fixedly connected to the locking pawl 8, and the other end is fixedly connected to the holding plate 5. In this case, the elastic member 11 is hung on the bent piece 12, for example.

The locking contour 13 is formed from a locking slit 14. The locking contour 13 or the locking slit 14 is formed so as to be self-suppressing with respect to the connecting rod 15 when it comes into contact with the back wall at the end point position. At this end point, the corner 16 of the locking pawl 8 grips the connecting rod 15 so that the connecting rod 15 does not come off the locking slit 14. This means that the corner 16 restrains at least a part of the vertex of the side surface of the connecting rod 15.

The connecting rod 15 is received by the bearing fork member 17 and further connected to the mounting arm 1 via the connecting plate 18.

Hereinafter, each step of assembling the external mounting mechanism will be described with reference to FIGS. 3A to 3D. FIG. 3a shows the mounting arm 1 and the support member 2 still separated. FIG. 3b
The mounting arm 1 and the support member 2 approach each other, and the connecting rod 15 is
7 shows the state introduced. As shown in FIG. 3c, the connecting rod 15 pushes the locking pawl 8 to the end point position, and the locking pawl 8 jumps up. This is achieved by the rod 15 rubbing against the circular head of the corner 16.

Finally, the connecting rod 15 gets over the tip of the hook, and the locking pawl 8 is fitted to the end point position as shown in FIG. 3D. At the end position, the corner 16 of the locking pawl 8 restrains the connecting rod 15 and fixes it in the use position. The connecting rod 15 serves as a rotation bearing for the backrest, and the backrest can be freely folded at any time.
