The invention relates to a vehicle seat locking mechanism that is arranged between an upper rail and a lower rail which can slide relatively and define a cavity between the upper rail and the lower rail. The vehicle seat locking mechanism comprises a torsion bar piece and a locking piece, the torsion bar piece is fixed on the upper rail and is provided with a torsion section and a free section integrally connected with the torsion section, and the free section is in a bent shape. A shaft body is included and is partially configured to be arranged side by side with the torsion section along thelength direction of the upper rail; the locking piece comprises a locking part arranged in the cavity and a force bearing part fixedly connected with the locking part, the locking part is rotatably arranged on the shaft body and locks the upper rail and the lower rail in a relative sliding mode due to the fact that the torsion section is arranged in a blocking mode, and the force bearing part isprovided with a force bearing end located outside the cavity; and the force bearing end is driven by an external force to enable the locking part to force the torsion section to twist so as to releasethe locking between the upper rail and the lower rail. Compared with the prior art, the structure is simple, the number of parts is small, the weight is low, the cost is low, and assembling is convenient.

    本发明涉及一种车辆座椅锁止机构,配置于可相对滑动、并于两者间限定出空腔的上轨和下轨之间,该车辆座椅锁止机构包括扭杆件和锁止件,扭杆件固定于上轨上,并具有扭转段,以及与扭转段一体连接的自由段,自由段呈折弯状,且部分被配置为并排于扭转段而沿上轨长度方向布置的轴体;锁止件包括配置于空腔内的锁止部,以及与锁止部固连的承力部,锁止部可转动的设于轴体上,并为因扭转段挡置而构成对上轨和下轨间相对滑动的锁止,承力部具有位于空腔外的承力端,且承力端承接外力驱使可使锁止部迫使扭转段扭转,而解除对上轨和下轨间的锁止。本发明相对于现有技术,其结构简单,零部件较少,重量较轻,成本较低,并可便于装配。
