Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seats and relates to an automobile seat. Background Art

[0002] At present, car seats are important interior parts installed in the interior of cars for passengers to sit on. In the market, a back panel is usually set at the rear end of the front seat of the car to facilitate the addition of a small table or leg rest. The back panel of the existing front seat of the car is usually a large integrated back panel. The large back panel of this structure is difficult to form due to its large area, and the manufacturing and use costs are high. Therefore, some front seats of the car with a small back panel design have begun to appear on the market. However, the design of the small back panel has the following shortcomings during use: the surface cover of the existing front seat of the car is usually made of soft materials such as PVC leather, PU leather or genuine leather, while the small back panel is usually made of hard materials such as plastic. At the overlap between the small back panel and the seat cover, the seat cover will have appearance defects such as wrinkles, stretching, and deformation, making the matching gap between the seat back panel and the cover uneven, thereby affecting the overall appearance of the seat. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose a car seat. The technical problem to be solved by the utility model is how to make the matching gap between the back plate and the cover of the car seat more uniform.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A car seat includes a seat back frame, characterized in that a fixed base is installed on the rear side of the seat back frame, a back plate located at the upper part of the seat back frame is installed on the fixed base, the lower side edge of the fixed base has a supporting flange bent backwards, an accommodating gap for setting a seat cover is formed between the back plate and the fixed base in the front-to-back direction, and a reserved gap only for accommodating and passing the seat cover is formed between the lower end of the back plate and the supporting flange, and the reserved gap is connected to the accommodating gap.

[0006] The present automobile seat is achieved by installing a fixed base on the rear side of a seat back frame, and then installing a small back panel on the fixed base. At the same time, an accommodating gap for the seat cover to be set is formed between the back panel and the fixed base in the front-to-back direction, and a reserved gap is formed between the lower end of the back panel and the supporting flange, which is only for the seat cover to be accommodated and passed through and is connected to the accommodating gap, so that the cover of the present automobile seat passes through the accommodating gap and the reserved gap in turn and then covers the lower part of the seat back frame. The joint portion between the flexible cover and the hard back panel is clamped up and down by the lower end of the back panel and the supporting flange, which are both hard, to avoid the appearance defects such as wrinkles, stretching, and deformation of the seat cover at the overlap between it and the small back panel, solve the problem of uneven soft and hard overlap, and thus make the matching gap between the automobile seat back panel and the seat cover more uniform.

[0007] In the above-mentioned car seat, the upper side of the fixed base has a guide flange bent forward, and a guide gap for setting the seat cover is formed between the guide flange and the back plate in the up-down direction, and the guide gap is connected with the accommodating gap and the reserved gap in sequence, and the cross section between the three is in a "Z" shape. By adding the guide gap, after the upper end of the seat cover is fixed to the hook-shaped portion of the seat back frame, the lower end thereof is bent in a Z shape and then passes through the reserved gap, and then is covered on the lower part of the seat back frame, thereby further limiting the deformation of the seat cover, so that the seat cover maintains a high stiffness after being covered.

[0008] In the above-mentioned car seat, the middle part of the back plate has an interface reserved groove that is concave forward, and a clearance hole is opened at the bottom of the interface reserved groove. The guide gap is formed between the lower groove wall of the interface reserved groove and the guide flange. By setting the interface reserved groove, the reserved interface can be hidden in the interface reserved groove. The reserved interface can be used to install the headrest screen, or the passenger can connect his mobile phone or tablet computer through this interface, and easily enjoy music or read books in the car. It is also convenient to set a foldable table (facilitating the connection between the table and the seat back frame, and at the same time, the table can be used as a cover after being folded), which greatly expands the function of the car seat, and can also be expanded differently according to different projects.

[0009] In the above-mentioned car seat, a cover plate is detachably provided at the notch of the interface reserved groove. The cover plate can cover the interface reserved groove to ensure a good appearance and can better protect the reserved interface in the interface reserved groove.

[0010] In the above-mentioned car seat, the fixed base is in the shape of a long strip and is arranged along the width direction of the seat frame, and the width of the reserved gap is consistent at different positions. By arranging the long strip fixed base along the width direction of the seat frame, the lower end of the back plate and the supporting flange can better clamp the upper end of the seat cover that passes through the reserved gap. In addition, the width of the reserved gap is consistent at different positions, so that the clamping force of the lower end of the back plate and the supporting flange on the seat cover is consistent, so that the matching gap between the car seat back plate and the seat cover is more uniform.

[0011] In the above-mentioned car seat, a rectangular auxiliary fixing seat is installed on the seat back frame, the auxiliary fixing seat is located above the fixing base, a headrest is arranged on the front side of the auxiliary fixing seat, and the upper end of the back plate is fixed to the rear side of the auxiliary fixing seat. By providing the auxiliary fixing seat, on the one hand, the auxiliary fixing seat can be used to further fix the upper end of the back plate, and on the other hand, the auxiliary fixing seat can also be used to fix the headrest, so that one item has multiple uses.

[0012] In the above-mentioned car seat, the two sides of the back plate are in an arc shape that bends forward, and the front side of the back plate has a plurality of mounting parts for fixing, and the plurality of mounting parts are distributed in the middle part and the upper and lower edges of the back plate. By setting the two sides of the back plate in an arc shape that bends forward, the back plate can be better wrapped on the seat back frame after being set, and the assembly of the back plate can be facilitated by setting the mounting parts. At the same time, the plurality of mounting parts are distributed in the middle part and the upper and lower edges of the back plate, so that the back plate is more tightly fitted after being fixed.

[0013] In the above-mentioned car seat, the fixing base is provided with a plurality of first fixing parts that are fixedly matched with the mounting parts and a plurality of second fixing parts that are used to be fixed with the seat back frame. By providing a plurality of first fixing parts and a plurality of second fixing parts, it is convenient to fix the fixing base with the seat back frame and to fix the back plate on the fixing base, and the assembly is convenient.

[0014] Compared with the prior art, the advantages of the present car seat are as follows: the present car seat allows the surface cover of the present car seat to pass through the accommodating gap and the reserved gap in turn and then cover the lower part of the seat back frame, and the joint part between the flexible surface cover and the hard back plate is clamped up and down by the lower end of the back plate and the supporting flange, which are both hard, to avoid the seat surface cover from having appearance defects such as wrinkles, stretching, and deformation at the overlap between it and the small back plate, and solve the problem of uneven soft and hard overlap, so that the fitting gap between the car seat back plate and the seat surface cover is more uniform, and a balance is achieved in terms of cost and shape.
