The invention provides an anti-diving turnover mechanism, a seat and a vehicle. Wherein the anti-diving turnover mechanism comprises a seat framework provided with an elastic seat basin; the middle shaft is connected to the seat framework and arranged on the front side of the elastic seat basin; the overturning support is rotationally connected with the middle shaft and comprises a supporting end and a driving end which are located on the two sides of the middle shaft, and the driving end is arranged on the lower side of the elastic seat basin in a suspended mode; the positioning piece is connected between the overturning support and the middle shaft and limits the overturning support to rotate relative to the middle shaft, and when the passenger dives to enable the elastic seat basin to press the driving end downwards, the positioning piece is broken, so that the overturning support rotates forwards and synchronously drives the supporting end to be lifted; the locking component is arranged between the turnover bracket and the middle shaft and is used for limiting the reverse rotation of the turnover bracket; the lower side of the overturning support is sunken to form a deformation groove, and the deformation groove is formed between the supporting end and the middle shaft. When the vehicle collides, the supporting end is kept in a lifting state to limit the passenger to dive, the impact force can be absorbed by the fracture of the positioning piece and the deformation of the overturning support, and the injury to the passenger is reduced.
本申请提供一种防下潜翻转机构、座椅及车辆。其中防下潜翻转机构包括设有弹性坐盆的座椅骨架;连接于座椅骨架上且设置于弹性坐盆的前侧的中轴;与中轴转动连接的翻转支架,且包括位于中轴两侧的支撑端和驱动端,驱动端悬空地设置于弹性坐盆的下侧;连接于翻转支架与中轴之间的定位件,限制翻转支架相对中轴转动,当乘员下潜使弹性坐盆下压驱动端时,定位件断裂,使翻转支架正向转动且同步带动支撑端抬升;设置于翻转支架与中轴之间的锁止组件,限制翻转支架的反向转动;翻转支架的下侧凹陷形成变形槽,变形槽设置于支撑端与中轴之间。车辆碰撞时,支撑端保持在抬升状态限制乘员下潜,定位件断裂和翻转支架变形能吸收冲击力,减少乘员所受伤害。
