Seat armrest support structure

Abstract

The invention relates to a seat armrest support structure. The seat armrest support structure comprises a mounting bracket fixedly connected to a seat framework and an armrest connected to the mounting bracket in a rotating mode. The mounting bracket is provided with a circular arc groove and a second circular arc groove, wherein the rotation center of the armrest serves as the center of the circular arc groove and the center of the second circular arc groove; a guide pillar and a second guide pillar are arranged on the armrest, wherein the guide pillar and the second guide pillar are inserted into the circular arc groove and the second circular arc groove respectively and slide along the circular arc groove and the second circular arc groove respectively when the armrest is rotated around the center; the guide pillar is further provided with an elastic supporting mechanism, wherein the elastic supporting mechanism enables the guide pillar and the second guide pillar to make contact with the bottom of the circular arc groove and the bottom of the second circular arc groove respectively so that double-point support can be provided for the armrest when the armrest bears downward pressing force which is larger than or equal to basic downward pressing force. According to the seat armrest support structure, the armrest can be provided with extra support when a seat armrest bears quite large pressing force, it is guaranteed that the armrest is stably supported, and a damage problem is prevented; meanwhile, a passenger can be reminded when the armrest bears quite large acting force, and therefore it is guaranteed that the seat armrest can be used safely.

Description

technical field [0001] The invention relates to a component structure for an automobile seat, in particular to a seat armrest bracket structure. Background technique [0002] In passenger cars, especially passenger cars, most of the seats are provided with rotatable armrests on the outside of the seats. The armrests can be used to block and protect the passengers in the seats, so as to prevent the passengers from getting out of the seats when the car turns at high speed or when an accident occurs. It can provide further safety protection for passengers on the basis of seat belts, and at the same time, the armrest can also provide a hand rest support function for passengers after sitting for a long time, thereby increasing the comfort of the seat. [0003] In the current car seat armrest design, most of them adopt the flip-up and retractable mode that is installed on the side wall of the seat. Just at the side end of the backrest of the chair. And in order to increase the f...

AI Technical Summary

Problems solved by technology

The handrails in the above two technical solutions can have better functional effects on the basis of realizing their basic functions, but the above two kinds of handrails are guide posts (pins) and arc grooves (slides) when deployed. Direct rigid contact, relying on the guide column (pin) to provide support to the armrest, which will not affect the connection between the armrest and the seat and the supporting structure when the armrest is not under a large pressure, but in actual use It often happens that the handrail is used as a fulcrum artificially to make it bear a large pressure. At this time, the large pressure will generate a large shear moment on the handrail connection and supporting structure, and it is easy to make the rotation shaft or guide post (pin) of the handrail The child) breaks, and this action process is difficult to find, so this structural deficiency will bring problems to the safety of the handrail during use
