Crank rocker safety lift seat

Abstract

Crank rocker type safety lift seat, the seat is arranged in the bottom compartment under the floor of the bus, the seat includes a seat surface and a backrest, the backrest is connected to one side of the seat surface and the distance between it and the seat surface can be adjusted Angle, the bottom compartment is equipped with a crank rocker mechanism that can drive the seat out of the bottom compartment or retracted into the bottom compartment, the electromagnetic brake motor is used as the power source of the crank rocker mechanism, and the seat along the floor of the bus There is a gap for the seat to pass through on the lifting path, and the bottom compartment is provided with a sealing device for sealing the gap after the seat is fully stretched out of the bottom compartment or retracted into the bottom compartment. The invention realizes the automatic lifting of the seat through the crank rocker mechanism. When the passengers need it without affecting the safety in the car, the seat can rise to a certain height, and the backrest can be opened to reduce the standing of passengers; When the space is not enough, the seat can be folded in the bottom compartment to save the space inside the compartment.

Description

technical field [0001] The invention relates to the technical field of bus facilities, in particular to a crank rocker type safety lift seat. Background technique [0002] At present, buses have become an indispensable means of transportation for people to travel. From the perspective of design and technical characteristics, buses are different from other large and medium-sized passenger cars (such as long-distance buses, tourist buses, group buses, etc.). There are passenger seats and passages for passengers to stand and walk on the floor above the bottom compartment. The top plate on the top of the bus body is provided with handles for passengers to assist when standing. It is required that the compartment has a large standing area. The entrance and exit are wide and there are more than two doors. This has caused the relatively poor condition of bus riding comfort. The reason for this is that the number of seats on the bus is limited. Passengers with long distances and i...
