Lamber support fastening device for car seats {Device for fixing a lumbar support on a car seat}

The present invention relates to a Lambda SUPPORT fastening device of an automobile seat, and more specifically, to support the lumbar support of the occupant of the vehicle so that the Lamber support can be easily inserted into the seat frame to improve ride comfort and reduce fatigue. By doing so, it is designed to increase the productivity according to the simplification of the binding operation.

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 weight and cost account for a relatively large proportion of the entire vehicle, weight reduction and economical structural design are required.

In addition, when the seat is seated on the seat, the seating position is finally stabilized, and the sense of the ride dimension according to the vibration characteristics of the seat, ie, the dynamic seating feeling and the seating position of the vehicle when driving or winding roads are assuredly. The hold property, which is a performance to save, is required as a design requirement of the sheet.

The seat structure located in the driver's seat and the driver's seat is largely divided into a seat cushion and a seatback and headrest.

In the seat cushion and the seat back, the structure in which the seat spring is mounted on the seat frame and the trim cover assembly is mounted on the seat frame is widely used.

The Lamber support is a mechanism for varying the lumbar support force in the upward dimension for the purpose of reducing fatigue during long driving.

Conventionally, the Lamber support is fixed to the seat frame at a position that supports the occupant's approximately lumbar spine in an approximately arc-shaped material having excellent rigidity, and its position is normal according to the position selection of the control lever exposed to one side of the seat. It consists of a two-stage variable structure that can project toward the lumbar vertebrae at a certain height from the state.

In general, the method of mounting the Lamber support to the vehicle seat is provided with a separate bracket on the strap frame, and then largely formed by a method of fixing by using a fastening means and a method of fixing the clip member.

Conventional fixing means formed in the above structure has a problem in that the productivity is reduced due to the increase in the number of working hours, since the installation of the lambda support using a fixing member such as bolt after forming a separate fixing bracket on the seat frame.

In addition, the method of binding using the clip member has the advantage of shortening the work maneuver, but in this case, a bracket for installing the clip member on the seat frame must be formed separately, and the structure is simply dependent on being fitted in a circular clip. Therefore, after a long time elapsed, there was a closed end such that the Lamber support was separated from the seat frame due to the occupant's load, or the clip member was broken.

An object of the present invention is to support the lumbar support of the occupant of the vehicle so that it is easy to position the Lamber support to the seat frame to improve the ride comfort and fatigue, so that the productivity by simplifying the binding operation can be increased The present invention provides a lambda support binding device for seats.

Another object of the present invention is to provide a lambda support binding device for an automobile seat that is easy to mount and to be firmly fixed without being separated from the seat frame even under the support load of the occupant.

Still another object of the present invention is to provide a lambda support binding device for an automobile seat to improve the merchandise and convenience.
