[0006] With the above structure, before the overall assembly of the seat, the frame, the foam and the seat cover can be assembled into a whole assembly independently. When assembling the seat overall, installing this whole assembly on the corresponding backrest frame and seat frame can complete the installation of the backrest seat cover and the seat cushion seat cover, which has the technical advantage of convenient installation.

[0007] Preferably: the installation groove is an annular groove formed on the circumferential edge of the rear side of the frame. With the above structure, it can ensure that the edge of the seat cover extends and covers the rear side of the frame, and the frame and the foam are completely wrapped, which is beneficial to improving the appearance quality of the seat.

[0008] Preferably: a guiding part with a triangular cross-section is integrally formed at the end of the clamping strip, and the upper and lower edges of the rear end of the guiding part exceed the upper and lower sides of the clamping strip, and anti-detachment protrusions are formed on the two side walls of the installation groove. With the above structure, the clamping strip can be quickly and conveniently clamped in the installation groove.

[0009] Preferably: a guiding inclined surface is provided on the inner side of the anti-detachment protrusion. With the above structure, the assembly efficiency can be further improved.

[0010] Preferably, a positioning groove formed along the circumferential direction is provided at the rear side of the surrounding frame. Positioning pieces are distributed on both sides in the width direction of the positioning groove, and locking holes are provided on the positioning pieces. With the above structure, it is convenient to fixedly connect the surrounding frame to the backrest and the seat frame skeleton of the seat.

[0011] Preferably, the surrounding frame is made of plastic. With the above structure, it meets the lightweight design and is convenient for production and manufacturing.

[0012] The present invention also provides an automobile seat, which is characterized in that it includes a backrest skeleton and a seat frame skeleton, and the above-mentioned automobile seat assembly is installed on the backrest skeleton and / or the seat frame skeleton.

[0013] With the above seat, it is more convenient to install the backrest cover and the seat cushion cover.

[0014] Preferably, a backrest back plate is installed at the rear side of the backrest skeleton. With the above structure, the compactness of the backrest structure can be ensured, and the appearance quality of the seat backrest can be improved.

[0015] The present invention also provides a method for assembling a seat cover, which is characterized by including the following steps:

[0016] Step 1: Sew the clamping strip on the circumferential edge of the cover.

[0017] Step 2: Cover the foam on the front side of the surrounding frame, cover the cover on the front side of the foam, and then fold the circumferential edge of the cover backward so that the cover wraps around the foam and the surrounding frame.

[0018] Step 3: Fix the clamping strip in the installation groove so that the surrounding frame, the foam and the cover are connected as a whole.

[0019] Step 4: Fix and assemble the surrounding frame on the backrest skeleton or the seat frame skeleton.

[0020] With the above assembly method, it has the technical advantage of convenient installation of the cover.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Before the overall assembly of the seat, the surrounding frame, the foam and the cover can be assembled into an independent integral component, and then the integral component can be installed on the backrest and the seat frame skeleton of the seat to complete the installation of the cover. Compared with the traditional seat cover hanging and installation process, it has the technical advantage of convenient installation.

[0023] 2. The edge of the cover can extend and cover the rear side of the surrounding frame, so that the surrounding frame and the foam are completely wrapped, which is beneficial to ensuring the appearance quality of the seat. Description of the Drawings
