Anti-submersion method and device for automobile rear row

Abstract

The invention discloses an automobile back row submergence preventing method and device. When no collision happens, a submergence preventing supporting point of an automobile back row is arranged outside a passenger sensing area, when a collision happens, passenger inertia movement thrust is used for driving the submergence preventing supporting point to enter a submergence preventing effective area, a passenger is prevented from submerging, and an automobile back row submergence preventing function is achieved. When no collision happens, the submergence preventing supporting point is locatedin a low position, the passenger cannot sense the submergence preventing supporting point when taking an automobile, a taking comfort effect is good, when the collision happens, the automobile back row submergence preventing function is achieved, energy generated by the collision can be absorbed as well, and the passenger is more effectively protected.

Description

technical field [0001] The invention relates to auto parts, in particular to an anti-submersion method and device for the rear row of an automobile. Background technique [0002] With the development of the automobile industry, the penetration rate of automobiles is getting higher and higher, and the market's requirements for the safety performance of automobiles are gradually increasing. As an important performance factor of safety failure, submersion has attracted the attention of the automobile industry, and various anti-submersion structures have been designed. [0003] At present, the anti-submersion structure of the rear row of the car is mainly the seat frame horizontal tube, the seat EPP frame, the body sheet metal protrusion, etc. Among them, there is a problem in these structures. In order to meet the effective area of ​​the anti-submersion arrangement, the The height of the submerged structure is relatively high, and it can be perceived by the occupant when ridin...

Problems solved by technology

[0003] At present, the anti-submersion structure of the rear row of the car is mainly the seat frame horizontal tube, the seat EPP frame, the body sheet metal protrusion, etc. Among them, there is a problem in these structures. In order to meet the effective area of ​​the anti-submersion arrangement, the The height of the submerged structure is relatively high, and it can be perceived by the occupants when riding, which brings about ride comfort problems, especially when the occupants sit in the front position.
