Problems solved by technology

Due to unreasonable structural design, the existing locking system has complex structure, many parts and high cost, which makes the weight of the vehicle seat heavier
In addition, the existing structure needs to open a large opening on the upper rail to realize the assembly of the locking system, which greatly weakens the structural strength of the upper rail

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vehicle seats, in particular to a vehicle seat locking mechanism. Background technique [0002] At present, the driving seat of most vehicles can be adjusted forward and backward, and the adjusted seat position can be locked by a locking system. The existing locking system mainly includes an upper rail fixedly connected with the seat, a lower rail fixedly connected with the vehicle body floor, and a pawl rotatably arranged on the upper rail, and a plurality of locks are respectively formed on the upper rail and the lower rail. The tooth window, so that when the pawl is stuck in the tooth window where the upper and lower rails overlap, the locking of the relative sliding between the upper and lower rails can be realized. Due to unreasonable structural design, the existing locking system has complex structure, many parts and high cost, which makes the weight of the vehicle seat relatively heavy. In additi...
