Technical Field

[0001] The utility model relates to the technical field of traffic seats, in particular to a steering seat. Background Art

[0002] As a business card of China, China's high-speed rail has gradually become the first choice for people's intercity travel. The steering seat effectively improves the riding comfort, but the existing steering seat is designed for lateral steering, and the front and rear rotation space of the seat needs to be reserved, resulting in low utilization of the compartment space. The utility model provides a steering seat, which is designed for longitudinal steering, greatly reducing the reserved space and improving the utilization of the compartment space. Summary of the invention

[0003] The utility model provides a steering seat, which aims to solve the problem of low space utilization in the carriage due to the large reserved rotation space for the front and rear seats in the existing high-speed rail transverse steering seat design. The utility model designs a steering seat, which uses a gear slider mechanism to change the position of the seat back to achieve seat steering, and completes seat limit and auxiliary steering through a double gas pressure rod mechanism, thereby achieving longitudinal steering of the seat and improving the space utilization rate of the carriage.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a steering seat, a backrest, a base, a seat cushion, a left armrest, and a right armrest, wherein the right armrest includes a rear support plate, a connecting rod, a movable slide groove, a rotating gear, a front support plate, a gas pressure rod 1, a fixed support, a fixed gear, and a gas pressure rod 2, characterized in that the internal structure of the left armrest is the same as that of the right armrest and is symmetrically distributed, the seat cushion is connected to the top of the base by bolts, the fixed gear is fixed to the side of the seat cushion by bolts, the fixed support is connected to the bottom of the base side by bolts, and the gas pressure rod 1 and One end of the second pneumatic rod is coaxially matched with the hole on the fixed support, and the other ends of the pneumatic rod one and the pneumatic rod two are coaxially matched with the holes on both sides of the rear support plate, respectively. The upper end of the rear support plate is coaxially matched with the connecting rod, the connecting rod is fixed to the backrest through a key groove, the upper end of the movable slide is fixed to the connecting rod through a key groove, the connecting rod end of the rotating gear is slidably matched with the movable slide groove, the gear end of the rotating gear is meshed with the fixed gear, the upper end of the front support plate is coaxially matched with the hole on the rotating gear, the lower end of the front support plate is coaxially matched with the hole on the fixed support, and the right armrest pin is fixed to the rear support plate.

[0005] The utility model has the following advantages:

[0006] 1. In the utility model, the rotating gear cooperates with the movable slide slot to change the position of the seat backrest to realize the seat turning, and the horizontal space is no longer used for turning, thereby increasing the seat capacity.

[0007] 2. In the utility model, the seat limiting and auxiliary steering are completed by a double pneumatic rod mechanism. Compared with the traditional steering mechanism, this steering mechanism has a simple structure, is more labor-saving, simpler to operate, and reduces harm to the human body.
