Embodiment Construction
[0025] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0026] See Figure 1 to Figure 6 , a self-locking mechanism for preventing inertial opening of the armrest of a seat, comprising an armrest body 2 and a seat back frame 5, the armrest body 2 and the seat back frame 5 are rotatably connected. A first bracket 13 is fixedly connected to the first side of the seat back frame 5 . The first bracket 13 is hinged with a self-locking limiting piece 16 , and a return spring 14 is connected between the self-locking limiting piece 16 and the first bracket 13 . The first bracket 13 is provided with an arc-shaped movement groove 18 , and the armrest body 2 is fixedly connected with a sliding shaft 22 , and the sli...

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.
Description
technical field [0001] The invention relates to the field of automobile machinery, in particular to a self-locking mechanism for preventing inertial opening of a seat armrest. Background technique [0002] With the maturity of automobile technology and people's growing needs for a better life, automobiles have transformed from a simple means of transportation to a multifunctional mobile platform. In order to meet the convenience needs of rear passengers, the rear seats of most models are equipped with middle armrests. [0003] For the convenience of passengers, the opening operation force of the rear armrest should not be too large, so when the car brakes suddenly or encounters a rear impact, the rear middle armrest, especially the multi-functional armrest with a large dead weight, will suddenly open due to inertia, increasing the Safety hazards for rear passengers. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the purpose of ...
