car seat structure

Abstract

An automobile seat structure comprises a seat support and a seat basin structure arranged on the seat support. The seat support comprises a first lateral framework and a second lateral framework which are oppositely arranged, the first lateral framework is provided with a first end and a second end, and the second lateral framework is provided with a third end and a fourth end. The seat support further comprises guide limiting parts oppositely arranged on the first lateral framework and the second lateral framework. The seat basin structure comprises a first seat plate assembly, a second seat plate assembly and a connection assembly, the first seat plate assembly is movably connected to the guide limiting parts, and the connection assembly connects the first seat plate assembly and the second seat plate assembly. When the automobile seat structure is in a first state, the first seat plate assembly is located at a first position, and when the automobile seat structure is a second state, the first seat plate assembly moves along the guide limiting parts to a second position and forms a groove structure together with the connection assembly. The automobile seat structure is low in manufacturing cost, and effectively reduces harm of the submergence phenomenon on passengers.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile seat structure. Background technique [0002] With the development of society and the improvement of people's consumption level, the number of cars is increasing day by day, and car frontal collision accidents occur frequently. When a collision occurs, the occupant will move forward due to inertia, and the thigh will press the front of the seat, causing the front of the seat foam to sag, which will lead to The occupant slides forward and downward along the surface of the seat. This phenomenon is called "dive". If the "dive" is too high, the occupant's legs will hit the lower part of the instrument panel and cause injury. At the same time, the seat belt will cause strangulation to the neck of the human body. endanger the safety of the occupants. In order to reduce this hazard, the existing technology generally adds anti-submersion beams or other structures to st...

AI Technical Summary

Problems solved by technology

However, the seat with this new type of seat anti-submersion mechanism has a high cost due to the need to use sensors and controllers for the control system, and the drive mechanism and hydraulic cylinders to control the movement of the drive shaft.

Furthermore, the collision time is only in the range of 150ms in the actual collision process, and the hysteresis time of the sensor and controller plus the movement time of the drive mechanism and hydraulic cylinder may exceed this collision time

Therefore, the reaction lag of this new type of seat anti-submersion mechanism will cause the seat cushion to be unable to move in place in time, resulting in the failure of the anti-submersion function, so the actual effect is not ideal
