Problems solved by technology

[0003] In addition, due to the narrow space for the feet of some models, it is impossible to install a fixed footrest, or the fixed footrest is designed to form a certain inclination angle with the floor, which will result in insufficient contact area between the driver's feet and the floor. During a frontal collision, the calf is subjected to a greater impact force

Abstract

The invention discloses an air sac device for protecting feet of a car passenger. The air sac device comprises an air sac, a sensor, an air generator and an air sac ECU (electronic control unit), wherein the air sac is arranged on a car floor of a transition area between a car front wall plate and the floor and at the position of feet of the car passenger. During collision of cars, the air sac ECU can control the air generator to inflate the air sac according to car state information detected by the sensor, so that the air sac can be inflated to protect the feet of the passenger.

Description

technical field [0001] The invention relates to automobile safety components, in particular to an airbag device for protecting the feet of automobile occupants. Background technique [0002] In the process of a frontal collision of a car, the driver's feet and lower legs are often the most seriously injured parts, because the deformation of the front wall of the vehicle body and the unstable support of the floor to the driver's feet will lead to sprained feet and severe calf sprains, etc. question. [0003] In addition, due to the narrow space for the feet of some models, it is impossible to install a fixed footrest, or the fixed footrest is designed to form a certain inclination angle with the floor, which will result in insufficient contact area between the driver's feet and the floor. During a frontal collision, the calf is subjected to a relatively large impact force. [0004] Therefore, especially in the process of frontal collision, in order to increase the contact a...
