JPH01317849A - Release adjusting device for seat belt with automatic release device - Google Patents

Abstract

PURPOSE:To surely prevent a secondary disaster by performing an automatic release by adequately delaying it with the existence of the air bag having a small hole in the seat belt device equipped with the device automatically releasing the fitting state of a seat belt at the collision accident generation time of an automobile. CONSTITUTION:The locking spring 6 engaged with a locking fitting 3 with a spring force is provided inside the lock case 1 from which the locking fitting 3 to which one end part of a blet is linked is freely detached. The releasing spring 15 releasing this locking spring 6 by pressing it is fixed to the tip part of the bearing body 9 freely slidably inserted into the lock case 1 and this releasing spring 15 suspends the tip part by the L shaped hook 17 provided in the lock case 1 ordinarily. At the time when the tip 12 of the releasing spring 15 is separated from the L hook 17 a L type supporting member 18 is provided at the separating side, the air bag 21 always in a inflating state provided with a small hole is installed between the inclined part 19 of this supporting member 18 and releasing spring 15 as well and the automatic releasing action of a collision time can adequately be delayed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on an amendment and addition to the earlier application No. 1983-228321 entitled "Seat belt with automatic locking device".

This invention relates to an unlocking adjustment device for a seatbelt with an automatic unlocking device.

The earlier application proposed that in the event of a car collision, seatbelts are automatically tightened at the same time as the accident occurs, in order to make it easier for the driver and passengers to evacuate themselves or rescue themselves from the vehicle that has been turned over or destroyed. It was to be unlocked. However, if the locks were unlocked immediately after a collision occurred, there remained a risk of secondary disasters occurring. In order to eliminate these deficiencies, the present invention provides a seatbelt unlocking adjustment device with an automatic unlocking device as described below.

The configuration is such that a locking fitting 3 for connecting a seat belt is inserted into the inside 2 of a key case 1, and an imaginary tip part 4 is provided which can be freely engaged and detached.
At the tail of the locking spring 6 which has a pusher 5 fitted, the lock case 1
It is fixed and provided on the inside 2 of the.

In addition, the interior 8 of the lock case 1 on the opposite side 7 from where the lock fitting 3 is inserted
A support cover 9 is slidably inserted into the lock case 1, and the tip end 10 is suspended under tension on a bent resistance ring 11 installed on the lock case 1. Next, a notch 13 is formed in the tip 10 of the support body 9, and an unlocking spring 15, into which the shaft 14 of the pusher 5 is inserted, is fixed by the rear piece 16 of the one end. At this time, the tip 12 of the unlocking spring 15 is suspended against the pressure by attaching a hook 17 to the lock case 1. In this configuration, the tip 12 of the unlocking spring 15 is attached to the inside 8 of the lock case 1.
An L-shaped support member 18 is provided on the side that vibrates downward due to the elastic force to perform an unlocking operation when the lock is separated from the unlocking spring 15 and the inclined portion 19 of the L-shaped support member 18. An elastic air bag 21 provided with ultra-fine holes 20 and kept inflated at all times is installed. Alternatively, it has the same effect as the air bag 21. Although not shown, a pump-type air cylinder is used. Seatbelt unlocking adjustment device with automatic unlocking device.

The method of use is to add the present invention to the earlier application No. 1983-228321 entitled "Seat Belt with Automatic Unlocking Device" and use it in the same manner as a conventional seat belt.

Next, it protects the bodies of the driver and passengers from impact in the unfortunate event of a collision while driving a car.

However, there are cases where the severity of the accident is severe enough to cause serious injury or loss of consciousness. In such situations, even if the person were to escape on their own or be rescued, conventional seatbelts could not be easily unlocked and became a hindrance. However, according to the invention of the above-mentioned application, at the same time as the impact is large in a collision, a strong tensile force is applied to the seat belt due to the inertia of the body. If 300 to 500 kg is applied, the support body 9 inserted into the lock case 1 is pulled backwards, and at the same time the resistance wheel 11 is succumbed to the tensile force, and the pin 22 inserted into the support body 9 is pulled backward. They are arranged in a line with a dimension l within the range of movement within the elongated hole 23 of the lock case 1. Therefore, the unlocking spring 15 fixed to the support body 9 is pulled back by the same l dimension, and the tip 12 is separated from the L-shaped fiber arm 17. Then, the unlocking spring 15 pushes the locking spring 6 downward with the released elastic force,
As shown in FIG. 3, it is removed from the lock fitting 3. This is the automatic unlocking effect. However, if this action is carried out quickly, the seat belt may be immediately removed from the body and a secondary accident may occur. If you think that 30 seconds and 1 minute later is appropriate when the fear is gone, you can adjust it in advance accordingly. Therefore, when the unlocking spring 15 pushes out the locking spring 6, it is restrained by the air bag 21 provided in the pushing direction, and the microscopic hole 2 of the air bag 21 is
The air is gradually pushed out and contracted. Accordingly, the unlocking action becomes slower and more time passes.

At this time, the unlocking time can be adjusted by using the extremely small hole 20 of the air bag 21
It is carried out appropriately according to the size of .

Based on the above, after a high-impact collision occurs, seatbelts are automatically unlocked after an appropriate amount of time has passed after the risk of secondary damage has been resolved, so there is no risk of rollover or destruction. This eliminates the problem of people losing their lives due to delays in self-evacuation and rescue due to seatbelts getting in the way, and it is now possible to wear seatbelts with peace of mind when riding in a car. , the object of the invention has been achieved.
