Description

[Detailed Description of the Invention] The present invention relates to a rear seatback frame in which a headrest that is detachably attached to the rear seatback is configured to be inexpensive and meet strength requirements.

Conventionally, the mounting structure of the headrest in this type of seat back frame is as shown in FIG.
It was common to have a welded cylindrical holder 03 that holds the headrest, so when a rear load is applied to the headrest, the strength is weak and cracks may occur in the welded part, making it difficult to repair later. Because of the difficulty, there was a desire for something that was inexpensive and had satisfactory strength.

The present invention was developed in view of the above-mentioned circumstances, and uses a pipe frame etc. as the main strength member, welds a holder for fixing the headrest, and also secures the curled part of the panel frame that receives the load from the rear of the headrest with a predetermined clearance. The present invention provides a rear seatback frame which is constructed such that the curled portion of the panel frame receives the rearward load on the headrest.

Embodiments according to the present invention are shown in Figs. 2 to 4 below.
This will be explained in detail based on the figures.

FIG. 2 is a perspective view of a rear seatback according to an embodiment of the present invention. Reference numeral 1 denotes a pipe frame having a generally rectangular skeleton and serving as the main strength member. A panel frame 2, which also serves as a luggage holder and external appearance, is fixed to the back surface of the pipe frame 1 by welding or the like. Further, the lower portions of two cylindrical headrest holders 3 on the left and right sides are fixed to the upper part of the pipe frame 1 by welding, and a predetermined clearance d is provided at the upper rear surface of the headrest holder 3, and the panel frame 2 The upper curled portion 2a is installed.

Here, the curled portion 2a of the panel frame
In addition to improving the rigidity of the panel frame 2, when a rearward load is applied to the headrest 4 attached to the headrest holder 3, the curled part 2a can receive the component force of the rearward load together with the headrest holder 3. It's becoming like that.

As explained in detail above, the rear seatback frame according to the present invention has a seatback structure with a pipe frame as the main strength member and a panel frame in contact with the back surface, and a cylindrical headrest holder for fixing the headrest. By installing it with a predetermined clearance from the upper curled part of the panel frame, the rear load of the headrest is received by the welded part of the headrest holder and the pipe frame, and also by the upper curled part of the panel frame. It has a simple structure, is manufactured at low cost, and satisfies the strength requirements.
