JPH08135273A - Door lock releasing device for automobile - Google Patents

Abstract

PURPOSE: To improve safety by a method wherein when a large impact is imparted to an automobile, an acceleration sensor is actuated to inflate a balloon and a solenoid valve or the like of a door lock device is actuated to automatically release the lock. CONSTITUTION: When an automobile comes into collision and abruptly stops, a signal of an acceleration sensor 1 causes a balloon before a driver's seat to inflate, protecting a driver. At that moment, a solenoid valve or the like of an automatic locking device 3 is actuated to automatically release automatic locking. Next, in the case of a manual locking, a solenoid valve for release is provided so that the solenoid valve is actuated upon a signal of the sensor 1 to release manual locking. Consequently, a door may not be cut by a cutting machine and people in the automobile can be rapidly rescued.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door unlocking device for unlocking a door when a large impact is applied to the vehicle.

[0002]

2. Description of the Related Art In today's automobiles, the door is automatically locked when the vehicle reaches a certain speed after starting. In addition, the door is manually locked during traveling. When the vehicle collides, the acceleration sensor inflates the balloon near the steering wheel to protect the driver's body.

[0003]

However, when the vehicle collides, the driver's body is protected by the action of the balloon. The door was hard to open because it was locked, and I had to use a cutting machine to rescue the person inside.

In view of the above points, the present invention is capable of automatically unlocking the door and easily opening the door from the outside when a large impact is applied to the automobile, and rescues the person inside. It is an object of the present invention to provide a vehicle door lock release device capable of performing the above.

[0005]

Therefore, the present invention is designed to unlock the door by the signal of the acceleration sensor at the time of impact of the automobile.

[0006]

When the impact occurs, the acceleration sensor operates to inflate the balloon, and at the same time, the solenoid valve of the locking device is operated to unlock the lock automatically.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. When the speed of a car door exceeds a certain speed, the door is automatically locked by the action of a solenoid valve. In addition, the door is manually locked when traveling. The vehicle has an acceleration sensor 1, and when the vehicle suddenly stops at the time of a collision, a balloon 2 set on the front face of the driver's seat operates in response to a signal from the acceleration sensor to inflate the balloon 2 with the air so that the driver's body is covered. Protect. At the same time, the solenoid valve of the auto lock device 3 is operated to automatically unlock the door. In the case of manual lock, a solenoid valve for releasing is provided, and this solenoid valve is operated by the signal of the acceleration sensor to release the manual lock of the door. As a result, the door can be opened from the outside to rescue the person inside.

[0008]

Since the present invention is constructed as described above,
The door lock device is automatically released at the time of a collision of an automobile, and it is not necessary to cut the door by using a cutting machine, so that the human inside can be quickly rescued.
