Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a seat belt device for a vehicle such as an automobile.

[0002]

[Prior art]

 With conventional seat belt systems, even if the vehicle is severely damaged or rolled over due to a collision accident during driving or a fall accident from a high place, the driver or passenger may be seriously injured or fainted. Although it was necessary to remove it manually, it was extremely difficult to remove the seatbelt by yourself and escape on its own, or to rescue it from the outside. In addition, when accidentally falling into the water, they could not possibly take off their seat belts, hindering their escape and often causing loss of life.

[0003] Therefore, when an automobile or the like encounters a collision accident, a sheet belt device that automatically comes off immediately is required. In addition, in cases other than accidents, it will be necessary to remove them by simple operations.

[0004]

[Problems to be solved by the invention]

 The present invention has been made in view of such a point, and has a purpose of having an excellent engagement action, and automatically disengages immediately when a car or the like encounters a collision accident. An object of the present invention is to develop and provide a seat belt device which is a seat belt device and can be easily unlocked by a simple operation even in cases other than an accident.

[0005]

[Means for Solving the Problems]

 The present inventors have conducted intensive research to achieve such an object, and as a result, completed the present invention. That is, in the present invention, the seat belt is characterized in that the tongue member is engaged with the buckle body by a mechanism attracted to the electromagnetic body installed in the buckle body, and the electromagnetic belt is excited by unlocking the seat belt. The present invention also relates to the present invention, wherein in the seat belt device, the unlocking of the engaged seat belt device is automatically performed by the tension between the belts due to an external impact on the vehicle body or the like. Or manually.

[0006]

[Embodiment of the invention]

 One of the features of the seat belt device of the present invention is that the tongue member is engaged with the buckle body by a mechanism induced by an electromagnetic body installed in the buckle body.

The electromagnetic body in the present invention is generally called a solenoid used in an electromagnetic valve or the like, and is excited by a DC current supplied from a battery in the vehicle, and is sufficiently attracted to instantly engage the tongue member. It has power.

Another feature of the present invention is that the unlocking of the engaged seat belt device is automatically performed by an external impact on the vehicle body or the like.

In the present invention, when a strong impact is applied to the vehicle body from the outside such as a collision of the vehicle body, the vehicle is installed in the buckle body due to strong tension generated in the buckle body joined between the belts. When the switch is operated, the excitation of the electromagnetic body is cut off, and the seat belt device can be unlocked by a spring or the like.

The buckle body is provided with, for example, a piston or a spring, and the time lag between the external impact and the unlocking can be adjusted by adjusting the position and distance of the piston, the strength of the spring, and the like.

Further, in the present invention, in addition to the automatic unlocking of the seat belt device due to a strong impact from the outside or the like to the vehicle body as described above, a switch, a button, or the like is provided from a fixed place such as a driver's seat. For example, the seat belt devices of all seats can be unlocked manually. If the electrical system is disconnected due to a failure of the vehicle body or submersion of the vehicle body, the seat belt device is unlocked immediately by the action of a spring or the like.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is a longitudinal sectional view and a partially open plan view of a seat belt device according to a typical embodiment of the present invention.

[0014] To put on the seat belt device, the rider first inserts the tongue member 1 from the insertion port of the buckle body 2, and when the passenger reaches the button 3, the electromagnetic body 4 is excited by the DC current supplied from the battery. The hook 5 is instantaneously attracted against the spring 6 and penetrated into a hole 7 formed in the tongue member 1, and the tongue member 1 is engaged with the buckle body 2.

Due to an impact from the outside of the vehicle body or the like, an extremely strong tension is generated between the belts 8 and 8 # that have fastened the occupant's chest and waist. As a result, the piston 9 in the buckle body 2 slides against the spring 10, and the end of the piston finally comes into contact with the switch 11 to operate, thereby cutting off the power supply to the electromagnetic body 5. As a result, the hook 5 is disengaged from the hole 7 by the repulsive force of the spring 6, and the engaged seat belt device is unlocked.

In addition, even when there is no impact from the outside of the vehicle body, the switch 11 of the seat belt device is actuated by a switch, a button or the like (not shown) from a fixed place such as a driver's seat, and the engaged tongs 1 Is released, and the seat belt devices of all the seats are unlocked.

[0017]

[Effect of the invention]

 The seat belt device of the present invention has an excellent engagement action by a mechanism that is attracted to and engaged with the electromagnetic body. In addition, when an automobile or the like encounters a collision accident, the seat belt device automatically comes off immediately. The present invention provides a seat belt device that can be easily unlocked by a simple operation even in a case other than an accident. The unlocking method of the seatbelt device of the present invention is applicable not only to automobiles but also to aircraft and the like.
