Description

Technical Field

[0001] This utility model relates to the field of automotive interior equipment technology, specifically to a seat support structure that avoids frame steps. Background Technology

[0002] With the development of urban public transportation, buses, as an important mode of transport, rely heavily on the comfort and stability of their seats for passenger comfort. The frame design of bus seats often aims to enhance structural strength or meet specific layout requirements, but in some areas, it creates a stepped structure. However, traditional seat frame structures present several inconveniences when dealing with such stepped frames: Traditional seat frame structures typically use metal tubing or sheet metal, fixed to the seat frame through welding, bolting, etc. When steps exist on the seat frame, the installation process becomes complex and difficult. On the one hand, the frame needs to fit tightly against the frame to ensure seat stability; on the other hand, the presence of steps makes it easy for the frame to interfere with the frame during installation, leading to insecure installation or even failure to install. This not only increases manufacturing costs and production time but may also affect the overall stability and comfort of the seat.

[0003] While some existing bus seat designs offer support structures for specific frame structures, most suffer from problems such as complex structures, high manufacturing costs, or poor adaptability. Therefore, there is an urgent need for a support structure that is simple in structure, low in cost, and adaptable to bus seat frames with frame steps. Utility Model Content
