Description

Self-supporting structure of automobile seat cover

Technical Field

The utility model relates to a car seat assembly field, in particular to car seat face cover fixed knot constructs.

Background

The automobile seat is generally composed of a foaming body, a framework and a surface cover, wherein the framework mainly plays a role in supporting, safety and protection in the function of the seat; the foam is mainly used for improving the comfort of the seat, and the mask is used for further enhancing the beauty and comfort of the seat.

The existing automobile seat cover is integrally formed by sewing sheet fabrics at different parts of a seat, the whole width of the seat cover is wrapped and fixed on a foaming body after being sewn, and the sewing position of the fabric is clamped in a groove of the foaming body. However, due to the lack of other fixing structures between the fabric sewing part and the foaming body, the surface cover is coated behind the foaming body, the problems that the sewing line of the connecting part between the surface covers is twisted, the sewing line is not straight, the appearance of the arc chamfer transition part of the surface cover is unsaturated and the like easily occur on the surface of the seat, the later-stage shaping and ironing modes are needed to be carried out manually, the working efficiency is low, and the consistency is poor.

The technical problem to be solved by the application is as follows: how to solve the stiff and smooth effect of the seat surface cover appearance of guaranteeing, avoid the seat suture distortion scheduling problem.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a self-supporting structure of a car seat cover, which is convenient to assemble and can improve the appearance quality of the seat cover.

The utility model discloses the technical scheme who adopts does: the utility model provides a car seat face cover is from supporting type structure, including face cover cut-parts and section bar, the face cover cut-parts includes cut-parts surface and cut-parts bottom surface, two face cover cut-parts link together through closing a stylolite, the section bar is including pressing from both sides the type bone and holding the portion, the section bar sets up in cut-parts bottom surface below, two clamp are held the type bone bottom and are fixed jointly and be equipped with the portion that holds that is used for holding the stylolite that closes, the portion that holds is formed through clamping the type bone fixed connection by a plurality of holding tanks, the longitudinal section of holding tank is upper end opening and lower extreme confined shape, two clamp are held the type bone and are set up respectively in the both sides that closes the stylolite, two clamp are held the interval that props between the type bone and are close to or keep away from each other along with two face cover thickness.

The holding tank is used for holding and closes a stylolite, and two clamps are held and are propped the type bone and be used for the fixed stylolite that closes in the holding tank, because two clamps are held and are propped the type bone and press from both sides the hookup location between the cut-parts of two covers respectively, and the clamp is held and is propped the type bone from two cut-parts bottom surfaces below respectively along the surface that the clamp propped the type bone and prop the cut-parts of cover, and two cut-parts surface connection departments can form a straight line along the surface that the clamp propped the type bone promptly, guarantee cut-parts surface connection department outward appearance and stick together and straight.
