 Conventionally, seatbelts and airbags have been known as safety devices for automobiles. The seatbelt is a safety device attached to the seat to fix the human body. If not worn, nothing would work as a safety device, and each time it was worn, it took time and effort.

The airbag is mainly attached to the handle and operates in the event of an accident. However, the strength of the airbag itself is low, so it is effective for small accidents in the front. However, a major accident, the engine room was severely damaged and the front part was lost, or the front glass was broken or the glass supporting part was bent inward, and a hard intruder came into the car, rolled over In the event that the ceiling is dented due to factors such as the above, it may not be possible to protect human life. Furthermore, once the bag was activated, it was not possible to use it continuously.

As described above, it is a safety device that compensates for the above-mentioned drawbacks and has been developed with an original idea.

The front glass safety device for an automobile according to the present invention allows the protector attached to the ceiling portion of the vehicle to fall or slide only in the event of an accident, and to provide a framework for the protector and a cushion. The material absorbs shocks and protects the human body. In order to operate only in the event of an accident, a switch is provided at the end of the vehicle body that can be operated by one to three impacts. The solenoid device of the metal fitting that fixes the connector is securely operated by the solenoid and fixed in a fixed place.

Normally, the protector is fixed to the ceiling at several places, the drop type protector drops on one side, and the slide type protector slides. Protectors in place can withstand significant loads. In addition, the protector protects the human body from hard intruders and glass fragments from outside, preventing the protector from being deformed or being thrown out of the car. The cushioning material wraps the framing material in a sandwich shape, absorbs the impact on the human body, and prevents human injury or death. If the collision is mild, the protector can be used many times by re-installing it at the original ceiling position, and immediately respond to a major collision immediately after a minor collision be able to.

When a car collides forward, the face and head are often plunged into the front glass, and a protector is placed between the car and the human body to minimize the actual travel distance and reduce the load and acceleration. Suppresses street hits. Safety device that uses a protector to prevent the human body from touching the front glass.

In order to maximize the safety effect of the protector, it is most suitable for each type of vehicle, such as passenger car, truck, sport, wagon, etc. It is required to adopt the operation type of the protector. For example, a passenger car has a relatively large space in the ceiling, and an actuation type and a fall type rear protector are suitable. For those who drive while sitting close to the handle, an actuated type and a protector with a front dropping type are suitable. Also, with the sporting power, the front glass has a large inclination angle and the ceiling has a small space, so that the operating type is less likely to touch the head with the sliding type protector. Are suitable. In addition, a dual safety device that combines the strength and stiffness of the protector and the softness of the airbag to operate simultaneously. In addition, In the case of the protection, the thickness of the protector is further increased to increase the safety. In addition to the front seats, a rear-bottom protection case for the rear seats is also available.

 The present invention will be described in more detail with reference to the accompanying drawings.

 Fig. 1 shows a car viewed from the left side to make it easier to understand the protector.The arrangement of the switch 4A, the front glass 9a and the protector 1 installed on the ceiling 3 is shown in Fig. 1. It shows.

 The protector shown in Fig. 2 shows the operating mode with the rear drop protector of the main type mounted on the car for easy understanding. The front 1X is used as a fulcrum, and the rear 1y falls on arrow G. As shown in Fig. 2, in Fig. 3 as well, a slide protector, which is a representative of another model, is attached to the car. It indicates that it is sliding.

FIG. 4 also provides a clear and detailed description of the drop protector-1. The protector integrated left and right has a layered structure in which the framing material is connected to the steel material 1b and the fixing bracket 3a as the traveling direction T of the vehicle, and is covered by the cushion material and the skin material. In the event of an accident, the left and right seats operate simultaneously. Normally, the fixing holes for the fixing bracket 3a are fixed to the ceiling in the car, and the sun visor is fixed to the mounting part with a strong screw. <The material of the fixing bracket 3a is a strong round shape of 10 mm or more. By using a spring pot, it can withstand the impact load. The fixing bracket passes through the pipe 1c of the protector, so the front part of the protector is the fulcrum. With the release of the electromagnetic device 5 on the fixed plate 5c at the ceiling, the rear part 1y falls with the force and weight of the spring 6a. From the installed ceiling Approximately 9 (The lock mechanism 4 is fixed at the location below. Even if a load of 100 kg or more is applied to the protector, it can be supported on the ceiling. Drop the rear part of the protector. It is a safety device that absorbs shocks.

 In addition, the safety device for passengers can be secured by attaching a device with a rear drop type to the ceiling above the rear seats.

 In addition, the above-mentioned drop-type protector is attached to the ceiling so that the front and rear directions are opposite to the traveling direction. By dropping the front part with the fixing bracket at the rear of the protector as a fulcrum, the danger of contact with the head even during operation from the ceiling can be eliminated.

 FIG. 5 illustrates the shape. The ceiling has a complicated curve. To match this curve, both ends L of the protector are bent downward to make the thickness uniform and enhance safety. In addition, the corners of the front lx were made larger to improve the adhesion to the ceiling, and the protector was installed as far forward as possible at an angle to the rear, making it possible to increase the overall area. Figure 6 explains the internal structure of an important protector along the cross-sectional view. The steel 1a is mainly used as the material of the frame 1a, which requires strength, and the pipe 1c is fixed by welding. When weight reduction is required depending on the vehicle type, use aluminum, reinforced plastic and carbon fiber based metal materials. The iron plate has a thickness of 2.3 mm! ~ 7 mm This is due to the difference between small cars and large trucks. This frame material provides strength and prevents deformation of the protector and intrusion from outside.

The cushioning material has a thickness of 30 m ir! ~ 70 mm. In addition, the outer part 2a that comes into contact first is relatively soft, and the inner part 2b is relatively hard, so that the impact is absorbed step by step and the damage to the face and head is minimized. The opposite surface is a relatively soft cushion material with a thickness of around 10 mm. As a material for cushion material Uses polypropylene for sponge and urethane. For the skin material 2c, use the same moquette and the like as the interior material of the car, and prepare many colors to match the interior of the car. At the bottom, there is a movable sun visor 10 to avoid sunshine.

 FIG. 7 illustrates the operating principle of the slide type protector. The basic structure of the protector 1 itself remains the same, but the spring 6 for sliding forward with repulsive force, the roller 7 and the rail 7a attached to the ceiling mounting bracket 7b Therefore, it is a sliding type that moves forward inside the front glass. When viewed from the side, the shape of the protector is curved as a whole, and the same curve is also attached to the rails on the ceiling to reduce the resistance due to the step during operation. The roller 7 is wrapped in three directions by the rail 7a, and the internal roller bearing rotates to move faster. In addition, two powerful springs that constantly pull the hook 6a of the protector forward accelerate the release of the electromagnetic device. As described above, this type is effective for a sport car in which the front glass has a maximum inclination angle as much as possible, is almost horizontal with the angle of the ceiling portion, and has a very small overhead space.

The dual safety device shown in FIG. 8 will be described. A small air bag 8 is built in the contact surface S side of the protector, and the air bag is ignited at the same time when the protector is activated. By combining both safety devices, it is possible to provide a strength several tens of times greater than the strength of your bag alone, and the performance of the protector itself can be used at the limit. <Fig. 9 Discusses the equipment needed to release the system. One of the two solenoids of the electromagnetic device 5 is used as the main side. The energized solenoid 5a pulls the arm bracket 5b in the X direction. The circular tip J that is hooked rotates and the protector is released. One solenoid 5c is used on the safe side and is pulled in the Y direction. If both solenoids do not operate at the same time, malfunction due to vibration will be protected. The housing is a safety structure that is not released. Industrial applicability

 As described above, the front glass safety device of the present invention can be mounted regardless of a passenger car, a truck, and other vehicle types for the purpose of vehicle safety. Seat belts and airbags, which belong to a different family, are suitable for use as forward safety devices, especially in vehicles, regardless of the magnitude of the accident.
