Abstract

The invention relates to a special school bus seat frame for students. The special school bus seat frame comprises a cushion frame and a backrest frame which is connected with the cushion frame through a connector, the backrest frame comprises an outer frame and a backing plate which is fixedly arranged inside the outer frame, the outer frame comprises an elbow pipe, a first connecting pipe and a second connecting pipe, one end of the first connecting pipe is connected with one end of the elbow pipe, one end of the second connecting pipe is connected with the other end of the elbow pipe, the upper portion of the backing plate is connected with the elbow pipe, left and right sides of the backing plate are connected with the first connecting pipe and the second connecting pipe respectively, and the backing plate is in an integral structure. The backrest frame of the school bus seat frame comprises the backing plate, so that the structural strength of the whole seat is even; meanwhile, the backing plate can absorb energy fully, so that damage caused by the structure of the seat to the body of a student passenger during collisions is reduced.

Description

technical field [0001] The invention mainly relates to a special school bus seat frame for students, which is applied to the school bus to protect the safety of passengers. Background technique [0002] With the increase in the number of school buses, the safety of students on the bus has gradually become the object of people's attention, and school buses with more guaranteed quality and higher safety performance are required to be put into use. At present, the framework of school bus seats in China mainly includes a cushion framework and a backrest framework connected to the cushion framework through connectors, wherein the backrest framework includes an outer frame and a plurality of steel bars welded in the outer frame. The strength distribution of the backrest skeleton structure of this kind of seat is uneven, and the steel bars are easily separated from the outer frame or deformed during a collision, making the high-strength parts protrude from the entire seat, which is...
