Description

Vehicle safety device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a vehicle, and more particularly, to a safety device for a vehicle that can safely protect a driver and a passenger from an impact generated when a vehicle collides with another vehicle or an external object.

In general, when a vehicle collides with an external object or vehicle when driving at a high speed, not only the material damage that causes the vehicle body damage, but also the driver and the occupant of the vehicle may cause injury or even fatal death. In order to minimize the safety belt installed on the seat of the vehicle, it prevents the driver and passengers from jumping forward or sidewards to protect the occupants of the vehicle and to install the airbags in front of the driver's seat and the passenger seat. In the event of a shock, the front of the vehicle collides to prevent injuries.

However, the safety device has a problem that does not help much when the front panel of the vehicle is crushed in the collision of the vehicle and the instrumental panel of the vehicle hits the occupant.

Accordingly, the present invention has been made to solve the above problems, to provide a safety device of the vehicle for protecting the occupant of the front seat from the instrumental panel which protrudes while the vehicle body is crushed during the collision of the vehicle There is this.

Safety device for a vehicle of the present invention for achieving the above object, the collision detection sensor for detecting the collision of the vehicle, and the rear second position from the first position of the front of the guide rail installed at a predetermined length in the rear A front seat installed to be slidably movable in a first position, the first seat means fixed to the front seat in a first position and opened according to a control signal of the collision detection sensor, and when the first seat means is opened, the front seat is opened. It is characterized in that it comprises a moving operation means for sliding and sliding while sliding to the rear, and the second fixing means for detecting and fixing this by sliding the front seat to the second position by operating the movement operation means.

According to the present invention having the above-described configuration, when the vehicle collides while driving, a control signal is outputted from the collision detection means that senses a shock generated at this time, and the control signal is output from the collision detection means. When it is input to the fixing means, the first fixing means is operated to open the front seat to the rear to be movable, and also to move the front seat to the rear by operating the movement operation means, and when the front seat reaches the second position, The detected second fixing means is operated to fix the front seat so as not to move in the second fixing position.

As the front seat moves quickly to the rear in the event of a collision, the driver and passengers in the front of the vehicle can safely protect even if the front of the vehicle is crushed or an impact caused by the collision of the vehicle occurs. It is.

Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention will be described in detail.

1 is a view schematically illustrating a safety device of a vehicle according to the present invention, and includes a collision detection sensor 10 for detecting a collision of a vehicle and a front rail of a guide rail 22 extending rearward by a predetermined length. Fixing the front seat 20, the front seat 20 is installed in the first position so as to be slidably moved from the first position to the rear second position, the front seat according to the control signal of the collision detection sensor 10 When the first fixing means 30, the first fixing means 30 is opened to move backward, the first fixing means 30 is opened, the front seat 20 is slid rearward by pushing the front seat 20 backward. Movement operation means 40 and, the movement operation means 40 is operated, the front seat 20 is sliding and reaches the second position is characterized by consisting of a second fixing means 50 to detect and fix this It is done.

Here, the collision detection means 10 is installed on the front surface of the vehicle body, for example, bumper, when the collision of the vehicle, and outputs a detection signal when the impact force generated at this time is more than a predetermined set value.

In addition, the front seat 20 is installed to slide on a pair of guide rails 22 formed parallel to the floor bottom 100 in the longitudinal direction of the floor, and a lower portion of the seat frame 26 supporting the seat back 24. The slide member 28 is formed to slide along the guide rail 22.

In addition, the first fixing means 30 is inserted into one of the continuously formed fixing grooves 32a formed in the sliding member 28 to fix the front seat 20 so as not to move the cock 34. ) And the actuator 36 which rotates the cock 34, and the cock 34 is normally fixed while being inserted into the fixing groove 32a of the front seat. When the detection signal is input from 10, the actuator 36 is operated to rotate the cock 34 to exit from the fixing groove 32a and the front seat 20 slides back and forth along the guide rail 22. The movable open state.

In addition, the movement operation means 40 is an inflator for generating a pneumatic pressure by exploding a predetermined explosive according to a sensor 42 for detecting a state in which the cock 34 is opened, and a detection signal output from the sensor 42. (inflater, 44), the rod 46 is composed of a cylinder 48 to slide the front seat 20 to the rear while extending the pneumatic pressure generated from the inflator 44, the first When the cock 34 of the fixing means 30 rotates and exits from the fixing groove 32a, the sensor 42 detects this, and the inflator 44 explodes by the detection signal output from the sensor. While being inflated to generate air pressure, the cylinder is operated to push the front seat 20 backward while the rod 46 whose tip is in contact with a predetermined portion of the front seat 20 is extended.

In addition, the second fixing means 50 is a sensor 52 for detecting that the front seat 20 has reached a predetermined position of the guide rail 22, and a detection signal output from the sensor 52 Actuator 54, which is operated in accordance with, the locking device 56, which is to be inserted into the fixing groove (32b) formed in the slide member 28 of the front seat while rotating in accordance with the operation of the actuator 54, the clamp ( 56 is composed of a sensor 58 that detects the operation of the operation, and the solenoid valve 60 to operate by the detection signal of the sensor 58 to block the air flowing into the cylinder 48.

Therefore, when the front seat 20 is moved backward to reach a predetermined position, that is, the second fixed position, the sensor 52 detects this and outputs a predetermined detection signal. The actuator 54 rotates the clamp 56 and is inserted into the fixing groove 32b of the slide member.

At this time, when the clamp 56 is inserted into the fixing groove 32b of the slide member, the sensor 58 detects this and operates the solenoid valve 60 installed on the air inlet side of the cylinder 48 to allow the inflator ( When the air flowing from 44 is blocked, the rod 46 is not extended to stop the front seat 20 at the second fixed position.

In the present invention having the above-described structure, the rear seat (not shown) located at the rear may be installed in a vehicle having sufficient space, such as when the passenger does not board or is empty, wherein the rear seat is present. The lower seat of the rear seat is folded to the upper seat back so that the front seat is not shocked when the front seat is pushed backward.

The non-specified sensor used in the above may be any sensor that detects the movement of a predetermined object, such as an optical sensor, a proximity sensor, or the like that is normally used.

According to the present invention having the above structure, when the vehicle collides with an external object while driving the vehicle, the front seat of the vehicle is moved backwards to cushion the impact force due to the collision, and the vehicle body is deformed to the inside by the collision to the front seat. This will prevent damage to the occupants located.
