Description

Automobile seat backrest

Technical Field

The utility model relates to a car seat back belongs to car seat's technical field.

Background

The automobile seat back is a portion where the upper body of the passenger contacts via the seat back cover, and requires cushioning performance. In the prior art, a seat back cushion is often formed of a foamed resin of polyurethane or the like, and a seat back plate is made of a hard material. However, the design needs to be improved in both comfort and safety, and the rationality of the design of the seat back directly affects the comfort of the passenger for riding the automobile.

Japanese patent publication No. JP2015071393A discloses a technical solution of embedding a member between a seat back and a seat foam pad, but in this technical solution the embedding member is harder than the seat foam pad in texture, which, although improving safety performance, still does not solve the comfort problem.

JP2019018654A discloses sewing a reinforcing material to a seat pan cover, but this is to solve the problem that the sewn part is easily broken, and the safety and comfort are not yet solved.

In addition, the prior art also has a technology of sewing three fabrics, but the resin foam cotton is influenced by tension at the sewing position of the three fabrics, the corners are easy to collapse, the gap between the resin foam cotton and the back plate is too large, and the fingers of passengers are easy to be injured.

Based on this, provide the utility model discloses.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned technical problem of prior art, the utility model aims at providing a car seat back, it sheathes in at the seat and installs suitable reinforcement structure, has guaranteed the security, has also improved the clearance between seat back and backplate, has realized the travelling comfort.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

the utility model provides a car seat back, by interior and be equipped with seat skeleton, seat foaming pad and seat face cover outward in proper order, the outside of seat face cover is provided with the seat backplate, be equipped with the reinforcement structure between seat face cover and the seat foaming pad, there is the overlap region between reinforcement structure and the seat backplate.

The reinforcing structure is a polygon.

The reinforcing structure has at least one curved corner.

The reinforcing structure is in a half U shape.

A hollow-out area is arranged between the reinforcing structure and the seat surface sleeve.

The reinforcing structure is fixedly arranged on the seat foaming pad or the seat surface sleeve.

The reinforcing structure is detachably arranged on the seat foaming pad or the seat surface sleeve.

The installation mode is sticking or sewing.

The reinforcing structure be a plurality of, one or more setting of a plurality of reinforcing structure is between seat face cover and seat foaming pad.

The two reinforcing structures are respectively arranged on the upper part of the seat back plate and positioned on two sides of the seat surface sleeve.

The utility model has the advantages as follows:

the utility model discloses a car seat back is provided with the reinforcement structure between seat face cover and seat foaming pad, has improved the clearance between seat face cover and the seat backplate, and need not to prepare other parts that are used for installing this reinforcement structure, has realized the biggest security under simplest structure, has also improved passenger's travelling comfort.

Detailed Description

The present invention will be further described with reference to the following specific examples, but the scope of the present invention is not limited thereto.

Example 1

As shown in fig. 1 and 3 to 6, in the present embodiment, the car seat back 100 is sequentially provided with a seat frame (located inside the seat back 100, which is not labeled in the present embodiment), a seat foaming pad (located inside the seat back 100, which is not labeled in the present embodiment) and a seat cover 1 from inside to outside, a seat back plate 2 is arranged outside the seat cover 1, a reinforcing structure 3 is arranged between the seat cover 1 and the seat foaming pad, the number of the reinforcing structures 3 is two, and the two reinforcing structures 3 are respectively arranged on the upper portion of the seat back plate 2 and located on two sides of the seat cover 1. This arrangement improves the seating comfort on the back surface of the seat while improving the clearance between the seat pan 1 and the seat back 2 without hardening the seat portion.

Preferably, the reinforcing structure 3 has at least one arc-shaped corner, and as in the present embodiment 1, the reinforcing structure 3 is formed into a half U shape according to the specific structure of the framework and the sponge, and is disposed along the seat back 2, so that the gap between the upper portion of the seat back 100 and the seat back 2 can be more effectively improved. And, have overlap region 5 between reinforcement structure 3 and the seat back 2, form fretwork district 4 between reinforcement structure 3 and the seat face cover 1. The existence of the hollow-out area 4 greatly reduces the sewing area, thereby reducing the turned edge upwarp of the area, reducing the gap between the seat back plate 2 and the seat surface sleeve 1 and leading the seat back plate to be smoother and more comfortable.

In this embodiment 1, the reinforcing structure 3 may be fixedly mounted on the seat cushion or the seat cover 1. The cushion can also be detachably mounted on the seat foaming cushion or the seat surface cover 1 according to the requirement, and the mounting mode can be sticking or sewing, and other methods known in the art can also be adopted for mounting. When adopting detachable installation, when it need to change parts such as seat foaming pad, the reinforcement structure 3 is demolishd very easily, and it can to change the back equipment again, and the dismouting is very convenient, is favorable to after-sales service, and practices thrift the cost. The detachable mode in this embodiment 1 may adopt a mode known in the art, such as plugging, and is not described herein.

The installation of the reinforcement structure 3 in this embodiment 1 is very simple, and can be installed in a sticking manner on the seat foam pad, and also can be installed when the seat cover 1 is sewn, and the whole seat back 100 does not need to prepare other parts for installing the reinforcement structure 3, thereby greatly improving the safety thereof. As shown in fig. 4 and 5, the seat cover 1 may be formed by sewing an outer fabric panel 11, and the sewing position line 12 is as shown in fig. 1.

Other embodiments

As shown in fig. 2, the number of the reinforcing structures 3 in the present invention is several, and one, two, three, four, five, etc. of the reinforcing structures can be arranged around the seat back 2. And the shape of the reinforcing structure 3 may be a polygon or there may be at least one arc-shaped corner, the hollow-out area 4 may be located inside or outside the reinforcing structure 3, as shown in fig. 7 and 8. Other structures and their connection relations are the same as those of embodiment 1, and are not described herein. This arrangement also improves the clearance between the seat pan 1 and the seat back 2, and improves the comfort of the seat back 100.

The above embodiments are only used for explaining the inventive concept of the present invention, and not for limiting the protection of the claims of the present invention, and all the insubstantial modifications of the present invention made by using the above inventive concept shall fall within the protection scope of the present invention.
