KR100285379B1 - Frame structure of front seat for adjusting motion of passenger at head-on collision of vehicle - Google Patents

Abstract

PURPOSE: Front seat frame structure for adjusting motion of a passenger is provided to prevent passengers from being injured by deforming downward with forming plural notches in the middle of the seat frame at a head-on collision. CONSTITUTION: Plural notches(2,2') are formed in the middle and lower part of a main frame(1) to decide the position of a front seat in a vehicle. The lower body of a passenger is inclined forward at a head-on collision of the vehicle, and the frame is pulled down. The seat is moved down, and the upper body of the passenger is bent toward a steering wheel. The notched part is bent momentarily, and deformed. Impact is distributed with placing the upper body in the steering wheel. The collision portion of the upper body is enlarged with guiding downward movement of the lower body. The passenger is protected from being injured with distributing impact by forming the notched part in the frame at the head-on collision.

Description

Front seat frame structure with passenger behavior control in front collision

The present invention relates to a front seat frame structure having a passenger behavior control structure in front of a vehicle, and more particularly, to reduce as much as possible an injury value of a driver during a front collision most occurring in a car accident.

When a front collision occurs during the high speed driving of a vehicle, the steering wheel column is pushed to the rear of the driver due to the engine invading the vehicle as shown in FIG. 3.

This causes the driver's head or chest to hit the top of the steering wheel, resulting in high injury.

In this way, the driver's head and chest are prevented from hitting the top of the steering wheel to form a displacement induction notch in the frame structure of the front seat to induce downward motion of the driver's hips in front of the crash, thereby reducing the collision surface of the driver's chest and head. It is to enlarge and to disperse impact force.

In general, the car body is installed on the frame, or directly connected to the suspension system to accommodate people or cargo, and is separate from the frame, integral with the frame, such body is the front body and underbody and It is divided into side body and rear body.

The front body is capable of sufficiently absorbing the impact energy through proper stiffness adjustment in the front and rear directions in order to alleviate the impact force of the room at the time of the frontal collision of the vehicle.

The underbody has a structure in which elements are reinforced by directly attaching a driving device such as a suspension device of an engine mounting transmission rear wheel driver.

The rear body is located behind the passenger compartment, and is generally composed of a portion of the cargo compartment and a portion of the side body and the underbody.

The side body is a structural member forming a side portion of the vehicle, and serves to suppress deformation of the vehicle during vehicle overturning and side collision and to secure durability.

The belt line upper section of each filler tends to be thinner to widen the watch, but the bending and torsional rigidity of the car body should be taken into account, and the lower end of the belt line has a larger cross section compared to the upper part and there are many areas where the rigidity changes rapidly, but the door It is manufactured in consideration of lowering the rigidity of the door.

As described above, the car body protects the occupant in the event of an accident. In particular, the front body protects the engine in the event of an accident and directly affects the safety of the driver and the front passenger during a crash.

However, the frontal collision is most severely injured by the inertia that is moving forward.

So the head and chest are the airbags that make up a safety device, and the knee part of the kneebolts.

In other words, the cushioning material is installed at the site of the submarine phenomenon in which the knee part is concentrated in front of the base during anterior collision.

However, in the absence of the airbag in front of the collision as shown in the above 3, the head or chest is strongly impacted by the steering wheel is severely injured or severely lose their lives.

In the related art, the body is reliant only on a hypothetical device called a nibolster corresponding to an airbag or a knee corresponding to the head or chest in order to cushion the human body. Safety was defenseless.

The present invention in consideration of all the disadvantages of the safety of the driver in the prior crash as described above by placing a displacement-induced notch in the frame structure of the front seat seats to induce the backward motion of the driver's hips in the event of a forward collision and the driver's chest and It is a phenomenon that the front seat seat frame is bent downward during frontal collision through numerous analytical experiments by expanding the impact surface of the head and spreading the impact force, and even if the hip of the human body is displaced downward and the upper body is moved forward, the head chest The conclusion is made that the whole part hits the steering wheel and the impact force is distributed. Thus, a plurality of notches are formed on the center bottom of the seat frame to complete a structure that is displaced downward based on the forward collision.

The construction and operation of the present invention disclosed in order to achieve the object as described above and to solve the problems of the prior art will be described in detail with reference to the accompanying drawings which are embodiments thereof.

1 is a front view of a conventional front seat frame structure,

2 is a front view of the front seat frame structure of the present invention,

3 is a displacement diagram of the front seat passenger during a front collision illustrating the logic of the present invention;

The present invention has a configuration in which at least two notches (2) (2 ') are formed in the central portion of the bottom surface of the main frame (1) which determines the vertical position of the front seat.

According to the present invention having the above-described configuration, when the front collision is applied to a vehicle, a phenomenon in which the hip portion is moved forward by a submarine phenomenon occurs first, and the force at this time is applied as a force to pull down the frame 1 so that the overall reinforcement is Insufficient notch (2) (2 ') portion is bent momentarily and is displaced by the curved phenomenon as shown in the dotted line state of FIG.

Then the hips of the human body sink downwards and are moved forward, and then the upper body, ie the head or chest, falls down on the steering wheel.

At this time, the lower body is already sunk, and the entire head chest is settled on the steering wheel, so that the impact force is dispersed to prevent injuries caused by local concentrated blows.

The present invention is a simple and clear structure to prove the human displacement by the submarine phenomenon through a number of experimental analysis and the conclusion that the movement of the head chest corresponding to this displacement state is also efficient for safety through the experimental analysis seated on the steering frame To form a notch.

Of course, the size and number of notches will be changed according to the strength and structure of the seat frame, but satisfactory action has been caused by forming at least two V-shaped notches in the center of the ground of the entire frame.

The present invention has solved all the disadvantages of the safety for the driver in the prior crash.

That is, the displacement-induced notch is placed on the frame structure of the front seat to induce a backward motion of the driver's hips during a frontal collision to enlarge the impact surface of the driver's chest and head, thereby dispersing the impact force.

This is a phenomenon in which the front seat frame is bent downward during a frontal collision through a number of analytical experiments.As a result, the bottom of the human body is displaced downward, and even though the upper body is moved forward, the whole head chest hits the steering wheel and the impact force is dispersed. It became.

The present invention has an effect that can be applied to a real vehicle as an analysis for preventing a fatal injury of the driver as a simple structure that forms a plurality of notches on the center bottom of the seat frame to be displaced downward based on the front collision.

Claims (1)

At least two notches (2) (2`) are formed in the center of the bottom surface of the main frame (1) which determines the upper and lower positions of the front seat of the vehicle. Phenomena are first generated and the force at this time is applied as a force to pull down the frame (1) so that the notch (2) (2`) part, which lacks the overall reinforcement, is momentarily bent to be displaced by curvature. Front seat frame structure with passenger behavior control structure in front of the car crash.
