DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt structure for an occupant of an automobile.

[0002]

2. Description of the Related Art The basic structure of a conventional seat belt is such that a shoulder belt led out from the belt retractor installed at the lower part of the side wall of the vehicle body through the inside of the vehicle body side wall is engaged with a hanger member installed at the upper part of the vehicle body side wall. The upper part of the occupant is restrained by detachably engaging the hanger member with a buckle provided on the side of the seat.
However, such a structure causes various problems as described below.

[0003]

First, in the structure of the above-mentioned conventional seat belt, in the driver's seat with the right handle, the shoulder belt is installed from the right shoulder to the left hip of the occupant. By the way, in a collision accident, if the same force of inertia is applied to both shoulders, there is no belt on the left shoulder,
The left shoulder will momentarily move forward due to inertia. That is, the left shoulder rotates with the right shoulder to which the belt is applied as a fulcrum. As a result, the right shoulder is likely to come off the belt, and in such a case, the restraint of the occupant must be limited to the waist belt. However, with the restraint of only the lower abdomen, it is not possible to avoid a forward tilting operation with the neck and waist as fulcrums, and the upper body must be bent sharply. Also, in the event of an accident when the driver turns the steering wheel to the right, the driver's body is swung to the left, and as a result,
As before, the right shoulder may come off the belt. It should be noted that a similar result can be obtained in a right-hand passenger seat belt or a left-hand driver seat belt only by reversing the relationship between the shoulders in the above situation. In addition, the occupant's posture in the event of an accident is often leaning forward, which makes it extremely difficult to find and release the belt buckle near the left waist with the right hand. Becomes Further, after the lock is released, the shoulder belt may be caught on the occupant's arm on the door side, which may delay the escape to the outside of the vehicle.

Second, in the conventional basic structure of the seat belt, each fulcrum of the belt is provided directly on the side wall of the vehicle body, and a part of the belt penetrates the inside of the vehicle body side wall. However, if the occupant's seat is deformed due to a strong impact associated with the accident, or if the seat back part is extremely inclined forward, the occupant's body is pinched between the locked belt and the deformed seat, causing excessive pressure. This may cause harm to the occupant's body and sometimes lead to rupture of internal organs.

Third, in the conventional basic structure of the seat belt, the belt is detachably locked to the buckle material. The unlocking method is generally to push a button provided on the buckle material. It depends. In this way, the release of the lock always requires the occupant to press a very limited part with his finger. However, when an accident occurs, the occupant falls into a panic state, and such an operation cannot be easily performed, and escape from the vehicle by itself is delayed. Furthermore, when the belt is not in a tension state but in a fully stretched state, it is necessary to pull out the belt from the buckle while pressing the button, which increases the complexity.

Fourth, in the basic structure of the above-mentioned conventional seat belt, the belt is fixed in a state of being in close contact with the occupant's body during normal running. However, this makes the driving environment uncomfortable and may hinder the driving operation.

The present invention has been made in view of such a problem, and an object of the present invention is to fix the belt portion in parallel to the vicinity of the occupant's chest to prevent the occupant from moving forward or excessively leaning forward. Prevention of the occupant due to deformation of the seat by preventing the occupant from being squeezed by providing the seat of the belt part integrally with the seat, and facilitating the release of the belt in an emergency by the electromagnet type manual release mechanism. An object of the present invention is to provide a seatbelt structure that does not hinder the smoothness of a driving operation by maintaining an interval between the vehicle and a passenger.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a two-point automobile seat belt structure in which a belt portion B is provided between locking devices 1 provided on both sides of an occupant seat S body. A hard object that can be bent at both ends
The occupant is provided with a clasp T made of quality protruding forward.
Keep a close distance to the occupant's body near the chest
Fixed in parallel in the vicinity of sea urchin rider's chest, the height of the installation position of the belt section B ends in the engaging device 1 comprises a plurality sectional selectable adjustment mechanism 2, an electric belt portion B at one end to one of the locking device 1 It is provided with a locking mechanism 1 which can be easily detachably locked via a magnet, and a belt portion B provided with an adjusting member 3 which can adjust the entire length of the discharge belt. In this way, since both ends of the belt are fixed in parallel near the occupant's chest, the belt does not come off the body in the event of an accident, preventing the occupant from moving forward and excessively leaning forward. Can be prevented. In addition, by providing a belt locking device integrally with the seat, when an accident occurs,
It is possible to prevent pressure on the occupant and the belt due to deformation of the seat. In addition, the provision of the electromagnet-type manual release mechanism allows the occupant to easily release the lock of the belt even in an emergency and in the event of an accident, thereby enabling quick escape to the outside of the vehicle. Also, during normal running, the belt portion is fixed at a fixed interval from the occupant, so that a comfortable driving environment and smoothness of driving operation can be realized.

[0009]

Embodiments of the present invention will be described below.

The locking device 1 is integrally fixed to the left and right sides of the seat S. Thus, even if the body of the seat S is deformed due to the occurrence of an accident, it is possible to prevent the occupant from being pressed between the belt and the seat. The locking device 1 is provided substantially symmetrically at the same position on the left and right sides of both devices.
The belt B positioned between the locking devices 1 is fixed in parallel near the front chest of the occupant. This allows
It is possible to prevent the body from slipping through the belt caused by the fixation of the so-called crossing like a conventional seat belt, and the excessive bending of the body at the neck and the waist resulting from the parallel fixation at the waist. Also,
The shoulder belt fixed to the cross hook is easily caught on the shoulder even when the lock is released, and it may be difficult to escape from the car smoothly, but since it is parallel fixed near the chest, Does not catch on any part. Further, even after the accident has occurred, the locking position can be easily found even when the accident is released, so that a calm response after the accident can be achieved.

Each locking device 1 is provided with an adjusting mechanism 2 that can adjust the set position of the end of the belt portion, that is, the height of the belt.
It is possible to select a plurality of heights. The selection method can be performed by the occupants manually, for example, a mechanism in which the end of the belt B is inserted and fixed in a predetermined box.

One locking device 1, for example, in the case of a driver's seat in a right-hand drive vehicle, the end portion of the belt portion B can be easily and detachably locked to the right locking device via an electric magnet. Locking mechanism 1 is provided. The power switch of the electromagnet is turned on while the engine is rotating, and turned off when the rotation of the engine is stopped. However, it is characterized in that power is transmitted to the magnet only when the battery is charged from the engine, the power generation operation, or the power generation device instead of the line from the battery. This causes an accident
After the incident, when the engine is stopped,
It is very easy for the occupants to get out of the car promptly.
It is possible to go out.

The belt portion B is provided with an adjusting member 3 for adjusting the overall length of the belt B. This allows
Crew members of different sizes can be provided with belts of appropriate length.

[0014] The belt portion is fixed at an interval without closely contacting the occupant's body. Thus, unlike the conventional seat belt, it does not always adhere to the body, and realizes a comfortable driving environment and a safe driving operation that can prevent an accident before it occurs. Specifically, each locking device
A stopper made of a hard material that can be bent and extended from the device 1
And the end of the belt B is fixedly fixed to the catch T.
One end of the belt B is detachably fixed to the locking mechanism 1.
It is. Then, as shown in FIG. 2 or FIG.
Part B maintains a certain tension in front of the occupant
It is fixed in the state where it was done.

As shown in FIGS. 9 to 11, it is preferable that the locking device in which the end of the belt portion is detachably locked is provided with a belt non-attachment alarm mechanism and a mechanism for releasing the alarm. Although the belt non-attachment alarm mechanism is a known technology, such an alarm mechanism generally has a lamp lit almost in front of the driver. However, drivers with illness are not legally required to wear a seatbelt, and for those who do not wear the alarm lamp, the non-arrival warning lamp is very troublesome and may even impair safe driving.
Therefore, by providing a mechanism for canceling the alarm together with the belt non-arrival alarm mechanism, such a problem can be eliminated.

[0015]

Since the present invention is configured as described above,
It has the following effects. When an accident occurs, it is possible to prevent the belt from coming off the body, prevent the occupant from moving forward, and prevent the occupant from leaning forward excessively. The compression of the occupant and the belt due to the deformation of the seat can be prevented. The occupant can easily release the lock of the belt even in an emergency in the event of an accident, enabling quick escape to the outside of the vehicle. It is possible to realize a comfortable driving environment and smooth driving operation.
