The invention discloses a self-locking mechanism for preventing inertia opening of a seat armrest, which comprises an armrest body and a seat backrest framework, the armrest body is rotatably connected with the seat backrest framework, the first side of the seat backrest framework is fixedly connected with a first bracket, the first bracket is hinged with a self-locking limiting piece, and the self-locking limiting piece is fixedly connected with the armrest body. A reset spring is connected between the self-locking limiting piece and the first support, the first support is provided with an arc-shaped movement groove, the handrail body is fixedly connected with a sliding shaft, the sliding shaft is arranged in the arc-shaped movement groove in a sliding mode, and the self-locking limiting piece can swing to the arc-shaped movement groove under the inertia effect. Therefore, the sliding shaft is prevented from moving. According to the invention, the rear-row middle armrest, especially the multifunctional armrest with large dead weight, can be prevented from being opened suddenly due to inertia.

    本发明公开了一种防止座椅扶手惯性打开的自锁机构,包括扶手本体、座椅靠背骨架,所述扶手本体与所述座椅靠背骨架可转动地连接,所述座椅靠背骨架的第一侧固接有第一支架,所述第一支架铰接有自锁限位片,所述自锁限位片与所述第一支架之间连接有复位弹簧,所述第一支架设有弧形运动槽,所述扶手本体固接有滑动轴,所述滑动轴可滑动地设于所述弧形运动槽,所述自锁限位片能受惯性作用摆动至所述弧形运动槽处,以将阻挡所述滑动轴运动。本发明能够避免后排中间扶手尤其是自重较大的多功能扶手由于惯性会忽然打开。
