Lambber support for car seats {Lumber Support for a Car Seat}

The present invention relates to a lambda support for automobile seats, and more particularly, between the wire frame provided up and down inside the seat, the open window is formed continuously in the transverse direction in the center of the base member so that the supporting portion is integrally formed therebetween. It is equipped with Lamber support, which supports the ridge and the lumbar region of the seat seated on the seat to improve the adhesion, improves the static feeling and improves the comfort, and the posture of the seat plane is disturbed and the spine is unreasonable. It is invented to prevent.

In general, the driver's seat of the vehicle and the auxiliary seat on one side thereof are provided with seats separated from each other with the console box interposed therebetween.

The seat is designed with comfort in mind so that the occupant's support is adequate to absorb vibrations from the road surface and minimize fatigue.

In addition, since the weight and the cost occupy a relatively large proportion with respect to the whole vehicle, it is necessary to reduce the weight and economical structural design.

In addition, when the seat is seated, the seating position is finally calmed down, and the seating dimension is sensed according to the vibration characteristics of the seat, that is, the seating position is dynamic while the vehicle is turning or when driving the winding road. The hold performance, which is a performance of protecting it easily, is required as a design requirement of the sheet.

On the other hand, the interior of the seat is provided with a Lamber support fixed to the wire frame, the Lamber support is composed of a base member for supporting the lumbar part of the occupant and a control device for adjusting the base member.

The Lamber support is a mechanism for varying the lumbar support force in the ascending dimension for the purpose of fatigue reduction and health preservation during long driving.

Therefore, through the Lamber support, the ride dimension drives the static seating feeling to finally have a calm position when seated on the seat, the sense of ride dimension according to the vibration characteristics of the seat, that is, the dynamic seating feeling and the turning or winding road of the vehicle. In this case, the seat may be provided with a hold performance, which is a performance that reliably protects the elevation.

Conventional Lamber support configured as described above is installed inside the seatback and selectively curved protruding, so that it can effectively support the elevated lumbar spine, but the curved protruding support plate only supports a part of the lumbar spine, so that the lumbar region There was a problem that could be applied.

In other words, if only a part of the lumbar spine is supported by the body structure of the ascending dimension, the disc plate of the back portion may be pushed and the back and the front part of the back may be stiffened when the disc plate of the back portion is pushed and stimulated for a long time. Pushing your buttocks forward can lead to unstable postures that can strain your spine.

Maintaining an unstable posture for a long time can lead to spondylosis, disc disease or scoliosis.

This leads to a final calm position, which leads to a loss of static seating, which results in loss of comfort when seated on the seat, which makes it easy to feel tired, and greatly threatens safety of the ride through drowsiness. There was a problem such as being done.

Hereinafter, a configuration and an operation example of the present invention for achieving the above object with reference to the accompanying drawings are as follows.

In the present invention, the Lamborgh support for automobile seat has a window 42 in the center of the base member 40 so as to support the chamfer and lumbar region between the wire frames 11 provided above and below the seat 10 in the transverse direction. By mounting a Lamber support in which the supporting part 41 is integrally formed therebetween, improving the adhesiveness with the lift dimension seated on the seat 10, improving the static feeling and enhancing comfort. The posture of the circle is distorted and the strain on the spine is to prevent in advance.

The Lamber support 50 includes a binding portion 20 for attaching to the upper and lower wire frames 11 of the seat 10 and a support portion 41 for supporting the chamfer and lumbar region of the occupant, and both backs of the human body. An elastic wing portion 30 supporting the rib portion is formed integrally with the base member 40.

The Lamborgh support 50 is formed of a synthetic resin material with strong elasticity, so that the lumbar part of the occupant can be stably supported even under a sudden impact load such as a load due to the weight of the occupant and a traffic accident, thereby increasing safety.

In addition, as shown in FIG. 2 at the rear of the base member 40, ribs are formed to reduce the burden of the load transmitted to the binding portion 20 and the elastic wing portion 30 to prevent deformation of the body. do.
