Description

Technical Field

[0001] The utility model belongs to the technical field of automobile structures, and more specifically, relates to an automobile seat assembly and an automobile. Background Art

[0002] With the rapid development of the automobile industry, automobile safety, energy saving and environmental protection are one of the design goals pursued by major automakers in automobile research and development today, and are also an important consideration indicator for consumers' purchasing intentions. The development and design of automobile seats has gradually evolved from early practicality to a development process with safety as the core; the design of seats not only considers the above points, but also ensures that domestic and international regulations and other requirements are met. The safety and comfort of rear seats are more easily overlooked during the design process. Therefore, the development of rear seats must not only consider the requirements of shape, cost, weight and human-computer interaction, but also focus on anti-diving, that is, anti-forward sliding design and passenger perceived comfort.

[0003] The dive phenomenon is an undesirable phenomenon in a vehicle collision accident. The main purpose of the anti-dive design of the seat is to cooperate with the seat belt to prevent the occupant's hips and legs from sliding forward during emergency braking or a head-on collision, avoid the body sliding down due to inertia, and thus reduce injuries.

[0004] At present, the main design measures for anti-diving seats are:

[0005] 1) Add a rigid crossbeam to the rear seat cushion frame, called an "anti-dive crossbeam";

[0006] 2) Add EPP blocks to the rear seat cushion foam to increase the cushion support strength;

[0007] 3) Add metal brackets to the rear seat cushions to increase the support strength of the seat cushions;

[0008] 4) Add metal brackets to the floor of the vehicle body, and match the seat cushion with the floor to increase the supporting strength;

[0009] Although the above measures can prevent diving and reduce injuries, there are still some shortcomings. Whether it is adding crossbeams and metal brackets to the seat cushion frame, adding EPP to the seat cushion foaming, or adding metal brackets to the floor, they all increase the hardness of the seat cushion in disguise and sacrifice the comfort of normal riding. Utility Model Content

[0010] The purpose of the utility model is to provide a car seat assembly and a car in view of the deficiencies in the existing technology, so as to solve the problem that the anti-diving structure of the existing seat design proposed in the above background technology can prevent the passenger's hips and legs from sliding forward when encountering emergency braking or a frontal collision, but sacrifices the comfort of normal riding.
