Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a device for releasing an automatic belt installed in a vehicle in an emergency such as a vehicle overturning, thereby facilitating the evacuation of a passenger.

[Prior art]

Among the automatic belts that automatically shift the seatbelt installed in the vehicle between the occupant restraint position and the release position in response to the door opening/closing operation, making it easier for the occupant to get on and off the vehicle, this belt is especially suitable for the center side of the vehicle. Fix the emergency locking retractor in a position near the seat of the
The diagonal type automatic belt device, which connects the pull-out end of the seat belt wrapped and stored in the emergency locking retractor to the upper part of the door opening side of the vehicle, uses a continuous seat belt from the shoulder to the waist. Compared to automatic belts that shift in response to the opening and closing of a door, the mechanism is simpler, less likely to break down, and more practical, making it popular in many quarters. By the way, in this type of conventional diagonal type automatic belt, in the event of an emergency such as a vehicle collision or rollover, the belt locking action of the emergency locking retractor may actually hinder the opening operation of the door connected to the tip of the seatbelt. Therefore, these seat belts are usually provided with a removable emergency release means consisting of a combination of buckles and tongues at the middle part or at the upper end on the door opening side, and by separating the seat belt from the door, the door can be opened. Considerations have been made to allow the passenger to escape easily. However, in the automatic belt device in which the seat belt is equipped with an emergency release means as described above, the seat belt can be easily disconnected by simply operating the buckle of the emergency release means, and the automatic belt can be attached and detached solely at the discretion of the occupant. Since the system is left to the will of the occupants, there is a concern that the vehicle may be used incorrectly, such as driving a vehicle without the automatic belt installed, and the safety of the occupants cannot be ensured. In order to overcome this inconvenience, a reserve belt of a predetermined length is used to connect the buckle and tongue of the emergency release means disposed at the intermediate position of the seat belt or at the upper part of the door opening side, so that the seat belt can be extended. When the seat belt becomes impossible, the engagement between the buckle and the tongue is released, the effective length of the seat belt is increased by the length of the spare belt, and if possible, the door opening operation necessary for the evacuation of the occupant can be performed. In addition to Shimenu, U.S. Patent No. 4,245,856 proposes an automatic belt emergency release device that ensures that the seat belt is always connected to the upper part of the door opening side even if the buckle is accidentally released during normal belt use. However, in the above-mentioned emergency release device, while the buckle and the tongue are engaged, the reserve belt hangs down in a loop shape and comes into contact with the opening/closing part of the door or the occupant's body, causing the seat belt to close. There is a concern that it may hinder dislocation. Of course, the loop-shaped spare belt can be folded and attached to the seat belt so that it does not get in the way, but the spare belt needs to have a considerable length depending on the vehicle type and door structure. As a result, this can extend to the parts of the seatbelt that come in contact with the body, impairing the feeling of wearing the seatbelt, and also tending to deteriorate the appearance of the seatbelt itself.There is still room for urgent improvement in this area. Ta.

[Problem that the invention attempts to solve]

The present invention focused on the problems that conventional automatic belts had, and fixed a through ring to the end of the seat belt that was pulled out from the retractor in the center of the vehicle, and then inserted it through the through ring and folded it back. By connecting the seat belt to the upper part of the open side of the door via the auxiliary seat belt, and providing the auxiliary seat belt with a removable buckle and tongue, extension of the seat belt is prevented in an emergency, and the door is closed. Even if it becomes impossible to open the auxiliary seat belt, simply detaching the tongue from the buckle provided on the auxiliary seat belt extends the effective length of the seat belt, making it possible to open the door and facilitating the evacuation of the occupant. In addition, the auxiliary seat belt is held in a tensioned state during normal use and is kept on standby so as not to interfere with opening/closing the door or restraining the occupant, thereby solving the above-mentioned problems.

[Means to solve the problem]

The configuration of the present invention to achieve the above purpose is to use a seatbelt that is pulled out from an emergency locking retractor placed near the seat on the center side of the vehicle and stretched toward the upper part of the door opening side to open and close the door. In an automatic belt device that can respond and shift between an occupant restraint position and a release position, a through ring is attached to the pull-out end of the seat belt, and a through ring is inserted into the belt insertion hole of the through ring at the upper part of the open side of the door. Insert the other side of the auxiliary seat belt with one end attached and fold it upwards, and sew a tong of a size that does not pass through the belt insertion hole of the through ring to the tip of the folded part of the auxiliary seat belt. It is removably connected to the buckle fixed to the auxiliary seat belt.
