Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a vehicle equipped with an automatic door lock device.

In recent years, from the perspective of improving safety, vehicles equipped with automatic door lock devices that detect vehicle speed and automatically lock all doors have become popular. In such a case, all doors remain locked, making it extremely difficult to rescue the injured from the outside, or making emergency escape from a submerged vehicle difficult. ing.

The present invention attempts to deal with such problems, and its main purpose is to automatically release the door lock device when a collision, fall, etc. occur, while the vehicle is stationary after the accident. In addition, if the vehicle is equipped with a power window device, the safety device automatically opens the window glass to facilitate rescue of passengers from the outside and also facilitates emergency escape from the passenger compartment. It is about providing.

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 10 indicates a lock release circuit of a known automatic door lock device installed in a vehicle, and reference numeral 20 indicates a lock release circuit of a known door lock device for a child protector. A release circuit is shown, and reference numeral 30 indicates an energizing circuit for opening a window glass in a known power window device. Each of these circuits 10, 2
0 and 30 are manual switches SW ₁ , SW ₂ ,
It is connected to an ignition switch SW ₄ via SW ₃ , and the ignition switch SW ₄ is further connected to an on-vehicle battery power supply B.

The lock release circuit 10 includes electromagnetic coils 11 and 12 for unlocking the door lock devices attached to both doors at the front of the vehicle interior, and electromagnetic coils for unlocking the door lock devices attached to both doors at the rear of the vehicle interior. 13 and 14, these electromagnetic coils 11 to 14 are energized to unlock each door lock device when the manual switch _SW1 is closed.
The lock release circuit 20 includes electromagnetic coils 21 and 2 for unlocking a door lock device for a child protector provided on each door located on both sides of the rear seat of the vehicle.
2, and these electromagnetic coils 21, 22
When the manual switch SW ₂ is closed, it energizes and unlocks the door lock device for each child protector. The window glass opening energizing circuit 30 is connected to electric motors 31, 32, 33, and 34 that drive power window devices attached to each door of the vehicle interior, and these electric motors 31 to 34 are connected to a manual switch SW. ₃ When closed, it starts in reverse and opens the window glass of each door.

The safety device of the present invention is applied to a vehicle equipped with the above-mentioned lock release circuits 10, 20 and window glass opening energizing circuit 30, and its main components include an impact detection sensor 41, a stationary state confirmation circuit. 42 and a control circuit 43 are provided. In such a configuration, the impact detection sensor 41 is installed in a part of the vehicle body so as to detect the impact applied to the vehicle body when the vehicle collides or falls and generates an output signal, and is connected to the vehicle via the ignition switch SW ₄ . and is connected to power supply B. The stationary state confirmation circuit 42 is connected to the impact detection sensor 41 so as to operate in response to the output signal of the impact detection sensor 41, detect when the vehicle comes to rest after a collision, and generate an output signal.
The control circuit 43 also includes slow acting relays R ₁ , R ₂ , R ₃ connected to the stationary state confirmation circuit 42 and normally open switches that are closed by the operation of each of these slow acting relays R ₁ , R ₂ , R ₃ . SW ₅ , SW ₆ , and SW ₇ are provided, and when each normally open type switch SW ₅ , SW ₆ , and SW ₇ is closed, the above-mentioned lock release circuits 10 and 20 and the window glass opening energizing circuit 30 are connected to the power source B. serves to connect to.

According to the safety device configured as described above, when the vehicle causes a collision or falls, the impact detection sensor 41 detects the impact and generates an output signal, and in response, the stationary state confirmation circuit 42 is activated and when the vehicle comes to a standstill after a collision or fall, the stationary state confirmation circuit 42 generates an output signal.

As a result, each slow relay R ₁ of the control circuit 43,
When R ₂ and R ₃ are activated and a predetermined delay time has elapsed, the normally open switches SW ₅ , SW ₆ , and SW ₇ are closed.
For this reason, each lock release circuit 10, 20 and the window glass opening energizing circuit 30 are connected to the power source B and energized, and the locks of each lock device that were automatically activated when the vehicle is running are released, and each The window glass of the door is opened.

As understood from the above explanation, in the safety device of the present invention, the impact detection sensor 41 exemplified in the above embodiment detects the impact when the vehicle collides or falls, and activates the stationary state confirmation circuit 42. This is because the control circuit 43 energizes each lock release circuit 10, 20 and the window glass opening circuit 30 of the power window device after a predetermined delay time based on the output signal of the stationary state confirmation circuit 42. This feature allows occupants of a vehicle that has collided or fallen to be easily rescued from the outside, and also allows occupants to escape from the window of a submerged vehicle in an emergency.
