Description

Vehicle seat safety protection device

technical field

The present invention provides a device that can quickly move and tilt a vehicle seat when it is subjected to an impact, especially a device that utilizes the impact force of a vehicle to make the body of the occupant on the seat move toward the vehicle when the seat belt is fastened. The action of the reaction force generated in the direction of the impact can slow down or counteract the inertial force caused by the impact, so as to prevent the occupants from impacting the facilities in the cabin and causing injuries or casualties.

Background technique

At present, vehicles need to be driven by humans. However, driving on the road not only requires good driving habits such as attentive driving and law-abiding concepts, but also needs to pay attention to road conditions at all times to avoid car accidents.

However, the driving of the vehicle still needs to be driven by human control, so the occurrence of a car accident cannot be avoided; yet, with the passive safety protection facilities of the existing vehicle, after having the safety belt protection, it is still easy to cause the body to be injured in a car accident. Violent shaking, and when the body collides with the auxiliary airbag (SRS), there are still common injuries and even casualties. Moreover, it is calculated that the impact force produced by the severe car accident is far beyond the basic safety conditions of the car factory. Therefore, the higher the speed of the car, the greater the impact force of the car accident, so it often causes heavy casualties to the occupants. This is not only the brokenness of the individual family, but also the social cost.

At present, how to add or improve the passive safety protection devices of today's vehicles to enhance the safety protection effect of existing vehicles and provide protection for the life safety of occupants is one of the most important issues at present.

The inventor of the present invention took "Research on Car Impact Safety Protection Seat" as the subject of research and discussion in the thesis title when he was studying in the research institute. The process includes: 1. It is necessary to know the whole process of vehicle impact in various directions , For example, the vehicle is forced to bounce, shift, tilt, etc., and at the same time, it also causes the occupants in the vehicle to produce the same actions as the vehicle. 2. Understand the actual scientific theories such as the structure of various parts of the human body and the biomechanics of the impact force that human beings can withstand in the face of a car accident. 3. Understand how the occupant's body moves in various situations such as the "swinging movement" of the body when the occupant is faced with impacts from various directions in the vehicle cabin, and the violent movements during the vehicle impact process. 4. It is more necessary to flexibly use the principles of kinematics and conduct in-depth research on how the occupants can avoid casualties in car accidents and the subjective and objective circumstances. 5. It is proposed that when the occupant wears the seat belt and in the case of a single or continuous vehicle impact or rollover, the body will use the action of the reaction force to offset the inertial impact force, reduce the violent swing of the body and avoid hitting the interior of the cabin And other ingenious design concepts, in order to achieve the effect of all-round security protection. 6. The design takes the vehicle seat as the action object. This device focuses on the hydraulic actuation force and the action method of the mechanical structure when the vehicle hits. After careful design, simulation analysis and comparison, it is more committed to the ideal conditions of low cost and high reliability of the function. It is hoped that the seat device will be more practical and reliable. popularization, and after hard research and repeated trials, the "vehicle seat safety protection device" of the present invention was finally improved and created.

Contents of the invention

The main purpose of the present invention is to solve the above-mentioned problems and provide a kind of seat quick moving and reclining device, which is respectively provided with a plurality of hydraulically actuated cylinders around the car shell, and the cylinder pipelines It is connected with each rapid moving and tilting device and the seat, and has the function of a "hydraulic check valve" device when the front direction, side direction, etc. are hit, so as to prevent the seat from being hit and moving in the direction of the hit, so that the car When the shell is subjected to a single or continuous impact in any direction or even rollover, the moving and tilting device can be quickly activated in the first time when the seat belt is fastened, so that the body of the occupant on the seat reacts in the direction of the vehicle impact Force displacement action, so as to slow down or offset the inertial force generated by the impact, and at the same time, it can also prevent the body from violently swinging and hitting the facilities in the cabin to cause casualties, so that the present invention can provide all-round protection for the occupants , In order to reduce the casualties of traffic accidents.

The second object of the present invention utilizes the same hydraulic actuation principle, wherein the two sides of the lower seat back are respectively provided with a wing, and a driving cylinder and two idler wheels are arranged in it, and the two ends of the driving cylinder spindle are A cable is respectively connected, and the other end of the cable is wound around a pivot that can drive the wing to rotate, so that when the mandrel of the driving cylinder extends outward, the cable can be linked simultaneously to drive the two wings to clamp the occupant The waist can increase the contact area between the body and the seat, and at the same time, the bones and muscles can act elastically, which can also reduce the violent swing of the body, especially the head and neck at the end of the body (this part is easy to cause heavy casualties. Organs and tissues), and secondly, it can prevent the occupant from leaving the seat and throwing out of the car to suffer more serious casualties.

Yet another object of the present invention is to provide a seat back with an action device that protrudes forward and upward, wherein when the car shell is hit by a vehicle directly behind, the upper edge of the seat back can instantly The forward and upward movement form is used to receive the occupant's head and neck to avoid fractures and other injuries.

Another object of the present invention is that, except that the above-mentioned upper seat back has the same action, the headrest will move rapidly in the direction of the impact force, so as to accept the head and neck of the body drive, so as to prevent the occupant from being injured.

Regarding the technique, means and effects thereof adopted in the present invention, a preferred embodiment is given in detail in conjunction with the accompanying drawings. It is believed that the above-mentioned purpose, structure and characteristics of the present invention should be understood in depth and specifically. .
