Dual-recliner looking structure of seat for automobile using inetial force}

The present invention relates to a dual recliner locking structure of an automobile seat using inertial force, and more particularly, by mounting a recliner using a slope structure on one side of the seat back and configured to operate by inertial force, It is to improve the safety.

In general, the vehicle seat is configured with various mechanisms to improve the convenience because the driver and the passenger to sit for a long time while driving.

Among the various mechanisms, a dual-recliner is provided to adjust the seat back rotation angle to fit the body shape.

The dual recliner is mounted to the rear of the seat cushion to support the lower part of the seat back, and is configured to operate at the same time, one on each side.

However, the existing dual recliner structure is not only complicated in structure but also needs to be mounted on each side of the seat back one by one, resulting in higher unit costs and eventually higher production costs, thus requiring improvement.

The present invention has been devised in view of the above, and in the dual recliner locking structure of an automobile seat using an inertia force formed by attaching a seat back to a rear of a seat cushion with a dual cleaner, the seat back is located on one side on a rotation axis. A conventional recliner is mounted, and a dual recliner locking structure for an automobile seat using an inertia force is provided by mounting a recliner using a four-sided structure that is selectively locked while being rotated by an inertial force on the other side thereof. There is a purpose.

In a preferred embodiment of the present invention, the slope structure is provided on the rotating shaft so as to be integrally rotatable with the seat back frame and is fixed to the fixed slope member made to be selectively locked / unlocked to the recliner bracket, and in place on the rotating shaft It is mounted to be rotatable and characterized in that consisting of a rotating slope member for selectively pressing the fixing slope.

The fixed slope member may further include a first member mounted inside the seat back frame and having a slope in close contact with the rotational slope member, and a second member positioned outside the seat back frame to be interlocked with the first member. It is made, but the second member is characterized in that the fixing projections protrude so as to be selectively locked / unlocked to the recliner bracket on the outer surface.

In addition, the rotating slope member is characterized in that the weight is provided at the top.

In addition, the rotating slope member is provided so as to be positioned in registration with the fixed slope member under the support of the elastic spring.

Hereinafter, with reference to the accompanying drawings, the configuration and effect of the present invention will be described.

1 is a cross-sectional view showing a dual recliner locking structure according to the present invention, reference numeral 100 denotes a seat back frame and 110 denotes a recliner bracket.

The present invention relates to a dual recliner structure for adjusting the rotation angle of the seat back on the seat cushion, wherein the dual recliner structure respectively recliners at both ends of the rotation shaft 120 which is the rotation center of the seat back on the seat cushion. One side of the recliner is used as it is manufactured in the prior art, while the other side is equipped with a recliner using the slope structure to operate by inertial force caused by a collision accident or sudden start or sudden braking using the slope structure It is done by.

Here, the slope structure is fixed to the seat back frame 100 and the fixed slope member 10 for fixing the frame to the recliner bracket 110, and the fixed slope member by friction with the slope while rotating under inertia force It consists of the rotational slope member 20 which pushes 10 outward.

In particular, the fixed slope member 10 includes a first member 11 mounted to the rotation shaft 120 to be positioned inside the seat back frame 100, the seat back frame 100, and the recliner bracket 110. It is composed of a second member 12 mounted between and selectively locking / unlocking.

The first member 11 has a slope 13 which is in contact with the rotating slope member 20 to be described later on one surface, is installed so as to move from side to side in the longitudinal direction around the rotation shaft 120 do.

In addition, the second member 12 is rotatably installed on the above-described rotation shaft 120 while the fixing protrusion 14 is protruded on an outer surface thereof, and in particular, the second member 12 can move together with the first member 11 integrally. Are connected.

Here, the second member 12 may be installed in a state in which the fixing protrusion 14 is separated from the fixing hole 111 formed in the recliner bracket 110 by receiving the elastic support of the elastic spring 15.

Accordingly, the fixed slope member 10 may be rotatable about the rotation shaft 120 integrally with the seat back frame 110, and in particular, the first member 11 may extend in the longitudinal direction about the rotation shaft 120. According to the movement, the second member 12 may also move in association.

The rotating slope member 20 is a cylindrical member having a slope 21 corresponding to the slope 13 of the first member 11 described above, and the rotating shaft 120 is brought into contact with each other. It is rotatably inserted into).

In particular, the rotating slope member 20 has a weight (22) is formed on the upper portion, the weight weight 22 is to increase the rotational force during rotation by receiving an inertial force.

In addition, the rotating slope member 20 is provided with an elastic spring 23 on one side, the elastic spring 23 is always the first surface 11 of the slope 21 of the rotating slope member 20. Let's keep in line with the slope (13).

Of course, since the rotating slope member 20 and the first member 11 are in a mating state in which the slope 13 and the slope 21 are in close contact with each other, the rotation slope member 20 is not rotated by inertial force. It always stays in registration.

Therefore, the rotation slope member 20 is rotated when an inertial force is generated due to a collision accident or sudden stop in the mating state between the slopes 13 and 21, thereby rotating the first member 11. The second member 12 is constrained to the recliner bracket 110.

As described above, the present invention is a dual recliner locking structure of an automobile seat using an inertial force formed by attaching a seat back to a rear side of a seat cushion, wherein the seat back is a conventional recliner on one side on a rotating shaft. The dual recliner locking structure of the car seat using the inertial force is characterized in that the recliner is mounted on the other side, and the recliner using the slope structure is selectively locked while being rotated by the inertia force. have.

1) Cost savings can be improved by providing a recliner with a simple structure that is operated by inertial forces caused by sudden or crash accidents.

2) The seat back will be fixed only in situations where the recliner should be fixed without always fixing the seat, for example, in a crash, sudden stop, or rapid start.
