Description

Automotive rear seat passenger protection device

Generally, in automobiles, there have been developed various devices that can protect the passengers of crashes and collisions of automobiles more safely. There are safety belts that have been developed and commercialized first, and airbags have been developed and commercialized have.

The seat belt (or the seat belt) is used for safely protecting the occupant in a secondary injury caused by an impact force such as a collision or a shock during a running of the vehicle, and the position of the occupant is fixed to the seat (front and rear seat) .

The seat belt is roughly classified into a two-point seat belt, a three-point seat belt, and a four-point seat belt depending on the number of support points for fixing the occupant to the seat. In terms of safety, The three-point seat belt is commonly used, and at the same time, the number of automobiles in which the seat belt is mounted on the rear seat is increasing.

In addition, it is obligatory to wear a seatbelt during the running of the vehicle, and the degree of injury of the occupant varies depending on whether the seatbelt is worn or not, even when the vehicle is running at a high speed of 30 to 40 Km / h.

The two-point type seat belt (lap belt) is a seat belt, which is called a lap belt in which two points are supported on the left and right sides of the waist, and a lap refers to a waist to a knee joint in a sitting position on a seat.

The three-point seat belt (lap ad diagonal belt) is a seat belt most widely used in a general automobile. The seat belt is fixed to two points on the left and right of the waist and one point above the shoulder to fix the occupant to the seat at three points. It consists of a lap belt that restrains the waist and a solder belt that restrains the upper body. It is called a three-point type seat belt, in which the two strands are connected to one line, the continuous three-point type seat belt, . The separate three-point seat belt is advantageous in that only the lap belt can be mounted. It is important that such a three-point seat belt be secured to the pelvis without the lap belt being caught by the abdomen.

The seat belt is an automatic belt which is mounted on the passenger at the same time as the seat belt is mounted on the vehicle. This automatic belt is also referred to as a passive belt because the passenger does not need to operate the seat belt, and is automatically mounted.

The seat belt is provided with a seat belt retractor for automatically winding the belt after it is pulled and used, and a device called a tension reducer for reducing the winding force of the belt in order to reduce the pressure feeling when the belt is mounted.

The above-mentioned caterpillar is generally classified into a non-locking emergency lock type. The non-locking type locks the length of the shoulder and waist belt, while the emergency locking type can freely extend and retract the belt during stopping or during normal driving. However, when a large deceleration is applied to the car at the time of collision, It is possible to lock the belt.

The air bag inflates the collision air bag between the driver and the steering wheel or between the occupant of the passenger seat and the instrument panel in the event of an automobile crash, thereby minimizing injury.

As the airbag system, there are two types of SRS airbag systems, which are designed for a large airbag system or a three-point seat belt, There is an electric type in which air bags are inflated, an electric type in which electric charge is sensed by a sensor and electric power is applied to the inflator, and a mechanical type in which the sensing device senses the electric charges and changes the ignition agent on the sunk.

The airbag has been developed and used as a side airbag provided inside the door in case of a side collision of an automobile.

Conventionally, the seat belt is installed on the front seat and the rear seat, respectively, so that the occupant wears the seat belt to prevent the body from being forwarded due to inertia when the vehicle crashes or collision, A child or an elderly person has a problem that even if a seat belt as described above is worn, the body is weak and the ROM is damaged by the seat belt.

In addition, there is also a problem that when a seat belt of a rear seat is worn by a child, the seat belt is manufactured based on the body of an adult, and the seat belt is pulled out from the seat belt.

The present invention relates to a rear seat occupant protection device for preventing a rearward seat occupant from accidentally colliding or colliding with an automobile, The present invention is characterized in that a protector is hinged to the door inner panel in the lengthwise direction of the upper end of the door trim of the rear door of the automobile so as to vary the position of the door inner panel so that the protector is placed on the chest or abdomen of the rear seat passenger And to fix the seat back to the backrest seat.

1 to 3 show a rear seat passenger protecting apparatus according to the present invention. The rear seat passenger protecting apparatus includes a protector 20 having an outer surface coinciding with a door trip 12 of a rear door 10, The hinge member 32 is formed on the door inner panel 3 so as to be hinged to the projector 20 and the fixing member 28 to fix the projector 20 and the hinge member 32 .

The front surface of the protector 20 has the same surface as the door trim 12, and a rod-like profiled beam 24 made of a material having a superior shock absorbing function in the longitudinal direction is inserted and coupled. A reinforcing portion having a concentric circle with the beam 24 is integrally formed on the outer surface of the beam 24, that is, the other surface of the front surface.

A hinge member 26 bent at right angles is provided at one side of the probe beam 24 of the codec 20.

The hinge member 26 of the protector 20 is fixed to the hinge member 32 formed on the door inner panel 30 by screwing the hinge member 32 with the fixing member 3.

The lower surface of the fixing member 28 is formed with a threaded portion, and the intermediate portion and the upper surface are formed in a magnetic shape.

A stud bolt is integrally coupled to a lower surface of a fixing member 28 formed integrally with the door inner panel 30. [

The protector 20 can be hinged to the door inner panel 30 in the longitudinal direction of the upper end of the door trim 12 of the automotive rear door 10 to vary the position of the door inner panel 30, The rear surface of the rear seat (14) is fixed to a backrest seat of the occupant's chest or abdomen. The front surface of the rear seat (14) has a curvature similar to that of the door trim (12) And a reinforcing part having a concentric circle with the profiled beam 24 is integrally formed on the rear surface of the proctor beam 24 and the hinge member 26 The door inner panel 30 is formed with a hinge member 32 protruding toward the vehicle interior direction and a hinge member 26 of the protector 20 is attached to the hinge member 32 Tightened with a butterfly nut (28) It will be fixed.

Reference numeral 16 denotes a seat belt of the rear seat 14, and reference numeral 22 denotes a receiving groove of the prodecutor 20. [

The effects of the present invention will be described with reference to FIGS. 2 and 3. FIG.

When the seat belt 16 is worn by the passenger (particularly the elderly person) on the rear seat 14 and then the front end portion of the prodctor 20 (the right side of the prodctor 20 in the drawing) (20) is rotated about the fixing member (28) which fixes the hinge member (2632), and then the passenger is placed on his / her abdomen or chest area and fixed by fastening the fixing member .

In this state, the passenger is fixed to the seat 14 by the seat belt 16, and at the same time, the seat belt 16 is secondarily fixed by the projector 20, thereby maintaining a safer state.

In addition, passengers can put their hands or arms on the chest or abdomen prodectors (20) to operate in a more comfortable position.

Therefore, the pedestrian 20 placed on the chest and abdomen can prevent the body or the body from instantly turning forward due to the inertia generated when the vehicle crashes or collides with the vehicle or when the vehicle suddenly stops, thereby preventing a safety accident.

Therefore, among the rear seat passengers, particularly, the elderly person can be securely fixed to the seat, and at the same time, it can be used as an armrest so that safety and convenience can be provided at the same time.
