Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1 and 2, a swing arm for mounting a foot rest of an automobile seat structurally comprises a swing arm body 1, wherein the swing arm body 1 is formed by integrally forming an outer connecting section 1a and an inner connecting section 1b, the outer connecting section 1a is of an arc-shaped structure, the inner connecting section 1b extends and forms from the inner end of the outer connecting section 1a to a direction close to the central line of the outer connecting section 1a, a welding groove 1c is formed in the end of the inner connecting section 1b, the welding groove 1c is of an arc-shaped structure, and the central line of the welding groove 1c coincides with the central line of the outer connecting section 1 a.

As shown in fig. 3 and 4, the leg rest B is assembled on the rear side of the backrest back plate a by the above swing arm in a turning manner, the rotating shaft 2 is rotatably arranged on the framework inside the backrest, in this embodiment, the center line of the welding groove 1c and the center line of the external connecting section 1a are also the axial line of the rotating shaft 2, the welding groove 1c at the end of the internal connecting section 1B is fixedly welded on the rotating shaft 2, the external connecting section 1a is connected with the framework of the leg rest B, the backrest back plate a is provided with the via hole a, in the rotating process of the leg rest B, the external connecting section 1a is turned into and turned out of the backrest from the via hole a, and the turning connecting structure enables the via hole a to be close to the cross section of the external connecting section 1a in size and small in size, thereby being beneficial to ensuring the appearance quality of the backrest.
