Embedded buffering closing-assisted locking mechanism for large-sized armrest

Abstract

The invention discloses an embedded buffering closing-assisted locking mechanism for a large-sized armrest. The embedded buffering closing-assisted locking mechanism for the large-sized armrest comprises an armrest; the armrest comprises an armrest framework assembly and a hinge assembly; the embedded buffering closing-assisted locking mechanism for the large-sized armrest further comprises a torque hinged support assembly and a locking and unlocking assembly, wherein the torque hinged support assembly comprises a torque hinged support connecting pipe and a first torque hinged support which isfixed at one end of the torque hinged support connecting pipe; the two ends of the torque hinged support connecting pipe are fixed on the hinge assembly after correspondingly penetrating through thetwo opposite side walls in the armrest framework assembly; the hinge assembly is fixed on a seat framework; the armrest framework assembly can rotate around the torque hinged support connecting pipe;the locking and unlocking assembly is mounted on the armrest framework assembly; after the armrest is in a folded state, the locking and unlocking assembly locks the first torque hinged support so asto lock the armrest framework; and after the locking and unlocking assembly unlocks the first torque hinged support, the armrest can rotate and turn over around the torque hinged support connecting pipe. According to the embedded buffering closing-assisted locking mechanism for the large-sized armrest, as the locking and unlocking mechanism is arranged in the armrest, small space is occupied, andthe application range is wide.

Description

technical field [0001] The invention relates to the technical field of chair armrests, in particular to a buffering and assisting locking mechanism for a built-in large armrest. Background technique [0002] As passengers' requirements for driving comfort increase, passengers (especially business people) have higher and higher requirements for the versatility and comfort of car seats, and the functions of mid-to-high-end armrests are becoming more and more abundant. The weight also increases, and the traditional armrest buffer mechanism is difficult to meet the requirements of high weight, long cantilever armrest buffer and reduced operating force. At the same time, in the closed state of the armrest, if the vehicle is rear-ended, the armrest will quickly If it is opened, there is a risk of blowing and hurting passengers. Therefore, the large armrest needs to be equipped with a locking mechanism to ensure that the armrest is always in the locked position without being affect...

Problems solved by technology

The armrest mounting bracket in this patent is arranged outside the armrest, occupying the space outside the armrest and affecting the arrangement of the seat adjustment mechanism

[0005] In addition, the buffer mechanism in the form of traditional friction pads can provide limited buffer force and cannot support the weight of heavy-duty armrests. Using pop-up gas springs as the buffer mechanism of the actuator requires a large layout space and needs to occupy the seat backs on both sides of the armrest. Space, when used as a 40 / 60 armrest mechanism, one side will protrude the interface, affect the appearance, and affect the layout of the seat adjustment mechanism, it is not suitable as an armrest platform mechanism
