Description

Front Seat Seatback Reclining Device

The present invention relates to a front seat seat back reclining apparatus, and more particularly, to provide an improved front seat to prevent the physical damage of the occupant by reclining the seat back of the front seat during the collision and collision.

Inside the passenger compartment of the car, passenger seats can be seated. On the front side, the driver's seat and passenger's seat are provided in a bucket or separator type where only one person can sit. .

The front seat as described above is coupled to the seat rail fixed on the floor of the room is provided with a sliding movement in the front and rear direction, the height adjustment function of the cushion plate and the reclining function of the seat back.

The front and rear sliding and seatback reclining functions to facilitate the occupant's convenience and to easily adjust the driver's posture, as well as is configured to take a comfortable break during the week and stop.

In the front seat, when the collision occurs, the front seat is momentarily moved in the direction of the instrument panel (front) or the rear seat (rear), causing physical damage to the occupant.

In the event of a collision or collision from the front, the front seat moves in the direction of the instrument panel, which causes the driver and passenger occupants to hit the steering wheel or the instrument panel and cause considerable unfairness.

In the case of a vehicle equipped with an airbag, it may collide with the cushion of the inflating airbag and cause injury or suffocation.

Especially in the case of high ground accidents such as trucks and collisions and collisions, some parts of the engine room or passenger compartment are pushed into the lower part of the trucks, causing serious injuries and injuries even when the airbag is inflated. Is quite high.

Conventionally, in order to prepare for such a collision or collision, the entire front seat is moved backwards or the seat back is reclined so that the device and functions that can minimize the injuries of the occupants have had a considerable problem when an accident occurs.

Accordingly, the present invention has been made to solve the above problems, and in order to minimize the physical damage of the occupant by reclining the seat back of the front seat when a collision or collision occurs.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is a front view showing a front seat of a vehicle for explaining the present invention, Figure 2 is an excerpt of the front seat of the vehicle to which the technology of the present invention is applied, Figure 3 is a configuration extracting the front seat seatback reclining apparatus of the present invention It demonstrates together as a figure.

The front seat 10, which is provided at the front of the passenger compartment of the vehicle, is provided with a cushion plate 11 for supporting the hip portion of the occupant;

The cushion plate 11 is hinged and is composed of a seat back 13 having a headrest 12 at the top.

The cushion plate 11 is coupled to the seat rail fixed to the floor is free to slide forward and backward of the seat rail, the seat back 13 is moved by the lever 14 provided on the side of the cushion plate 11 It is configured to free reclining in the rearward direction.

The lower plate 21 is fixed to the cushion plate 11, and the upper plate 22 is fixed to the seat back 13, connected to the hinge shaft 23, and rotates together with the seat back 13 on the hinge shaft 23. A sector gear 24 is provided.

The sector gear 24 is connected to the lock gear 26 fixed by the lower plate 21 and the pin 25, and the lever 14 is connected to the front of the lock gear 26 so that the lever 14 is connected. The seat back 13 is thereby reclined.

The hinged shaft seat 23 has an inner end connected to the hinge shaft 23 and an outer end of the seat back 13 reclined through a spiral spring 28 fixed to a stop pin 27 protruding from the upper plate 22. It is configured to help the recovery of the.

The present invention further includes a seat back reclining apparatus 30 that minimizes physical damage of the occupant by allowing the seat back 13 to be reclined rearward when a collision or collision occurs.

The seat back reclining apparatus 30 is provided below the lever 14 connected to the sector gear 24 on the side of the cushion plate 11 to control the lock gear 26 for selecting reclining and unclining. A lever actuator 31 for operating 14;

The stop pin actuator 32 is provided to push the stop pin 27 supporting the outer end of the spiral spring 28 interposed on the hinge shaft 23 so that the seat back 13 is reclined backward.

The lever actuator 31 and the stop pin actuator 32 are operated by the controller 34 receiving information of the collision detection sensor 33 provided in front of the vehicle, and the controller 34 is provided in the driver's seat. It is possible to determine whether the operation by the operating switch 35.

The lever actuator 31 and the stop pin actuator 32 are solenoid type having a plunger (piston; 36) to operate by receiving an electrical signal from the controller 34, or by a ignition agent filled therein. Various types, such as a type in which the launcher 36 protrudes (extensions), may be used.

Looking at the working relationship of the present invention configured as described above;

First, the operation switch 35 provided around the driver's seat is turned on so that the controller 34 can operate normally.

If a collision or collision accident occurs in this state, the collision detection sensor 33 applies this information to the controller 34, and the controller 34 immediately operates the lever actuator 31 and the stop pin actuator 32. By allowing the seatback 13 to be reclined backwards, physical damage to the occupant can be minimized.

Referring to this, when collision or collision occurs, the controller 34 operates the lever actuator 31 to cause the plunger 36 to raise the lever 14 so that the lock gear 26 connected to the lever 14 is connected to the sector gear ( The connection with 24) is released.

At the same time, the plunger 36 of the stop pin actuator 32 is extended to push the stop pin 27 so that the seatback 13 can be reclined backwards.

The present invention as described above can minimize the physical damage of the occupants by reclining the seat back of the front seat in the event of a collision, collision has the effect of protecting the occupants safely.
