Abstract

The invention discloses an overturning locking mechanism for an integrally-turnable passenger seat of large-sized and medium-sized buses. The overturning locking mechanism comprises rotating shafts, locking mechanisms and pulling handles, wherein each rotating shaft is arranged on a support seat, and seat bodies are rotatably connected with the rotating shafts; lock tongues of each locking mechanism are fixed on the corresponding seat body, lock pins are fixed on each support seat, and the lock pins and the corresponding lock tongues cooperate lock up the seat; the lock tongues can be driven to rotate through transmission mechanisms connected with the lock tongues, so that the lock tongues can be separated from the corresponding lock pins for unlocking, and further, overturning is realized. According to the invention, the integrally-turnable passenger seat can be integrally turned directly by virtue of the connection between the rotating shafts and the support seats, so that the operation is convenient; through the arrangement of the locking mechanisms, the seat bodies and the corresponding support seats can be locked up when the seat is not required to be turned, so that the stability of the seat is guaranteed; when the seat is required to be turned, the handles are pulled to separate the lock tongues and the lock pins, and the seat bodies can be directly turned, so that the operation is simple, and misoperation and potential safety hazard are avoided.

Description

technical field [0001] The invention relates to the technical field of passenger car seats, in particular to a turning and locking mechanism for integrally turning passenger seats of large and medium-sized buses. Background technique [0002] At present, the reversible passenger seats of large and medium-sized buses are generally fixed by the seat body, and the seat cushion is reversible. The pedal control at the lower part of the seat, because there are passengers behind the flipped passenger seat, it is easy to step on it by mistake, posing a safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a turn-over locking mechanism for passenger seats in large and medium-sized passenger cars, which adopts a handle for turning control, and is provided with a locking mechanism to ensure the stability of the seat. [0004] Technical scheme of the present invention is: [0005] A flipping and locking mechanism ...
