Problems solved by technology

When in use, the seat can make the occupant feel comfortable, but it lacks certain safety measures, especially when a collision accident occurs, it lacks an effective protection device, so it has become less and less suitable for the needs of society

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0026] The overall shape of the seat of the present invention is similar to that of the currently used seat, so that the riding comfort and the overall rigidity can be guaranteed.

[0027] As shown in the figure, the seat of the present invention is an integrated device, and the headrest 1 is a rotatable headrest, which contains soft fillings and can be controlled by the first micro-motor 4a and the first control unit 5a to achieve rotation. The output shaft 3b of the first micromotor 4a is connected with the gear meshing mechanism 3c, the planetary gear of the gear meshing mechanism 3c is set together with the planar rotating mechanism 3a, and the planar rotating mechanism 3a is rigidly connected with the headrest 1 .

[0028] When an accident occurs, such as a positive collision with a rigid object, the sensor 13 will evaluate according to th...

Abstract

The invention discloses an automobile safety seat, comprising a seat, a headrest, an air bag, a first micro motor, a second micro motor, a first control unit and a second control unit, wherein the first control unit applies a pulse to the first micro motor according to a collision signal to control the rotation of an output shaft of the micro motor so as to drive the rotation of the headrest; thefirst control unit gives out an explosion instruction according to the collision signal to control the explosion of the air bag; the second control unit applies a pulse to the second micro motor according to the collision signal to control the rotation of an output shaft of the micro motor so as to drive the seat to move backwardly wholly. By using the headrest in the invention, the collision force between cervical vertebras of drivers and the headrest is greatly reduced; the impacts to the breasts of passengers after the explosion of a front safety air bag are greatly reduced due to the backward movement of the seat; and the impact force caused by the back rebound of passengers is greatly reduced because of the back of the seat.

Description

technical field [0001] The invention relates to a driving safety product for a passenger car, in particular to a novel car safety seat for the purpose of protecting the body of the occupant. Background technique [0002] With the development of society and the expansion of city scale, traffic is becoming more and more congested, and correspondingly, the probability of traffic accidents is also rising sharply. After analysis, it is found that when a collision accident occurs, the position process of the occupant's body is as follows: first leaning forward as a whole, and then reaching the maximum displacement under the joint action of the seat belt and airbag, and then returning to the original position under the pull back force of the seat belt (head in contact with headrest, torso in contact with seat back) (see image 3 ). During this process, the airbag will have a great impact on the chest of the occupant. At the same time, when the human body bounces back, the contact ...
