Description

A fixing structure for the side wing cover of a car seat Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to a fixing structure for the side wing cover of an automotive seat. Background Technology

[0002] Side airbags are typically installed inside the side wings of the seats. When a vehicle is involved in a side collision, the side airbags inflate rapidly to protect the passenger's side body, preventing them from being pushed against the door or struck by external objects. To prevent leakage of the side airbags, foam and protective coverings are usually provided on the mounting cavity surface of the side wing plastic frame assembly.

[0003] The existing cover is attached to the surface of the mounting cavity by an extruded clip. Specifically, there are snap-fit ​​grooves around the mounting cavity with multiple snap-fit ​​points. The side of the cover opposite the mounting cavity is a one-piece extruded clip formed by the four sides. The cover is secured by the one-piece extruded clip engaging with the snap-fit ​​grooves around the mounting cavity. However, because the shape of the extruded clip cannot perfectly match the shape of the snap-fit ​​grooves, the cover at the mismatched position will have a downward depression due to lack of support. This not only reduces the texture of the cover but also fails to meet the customer's requirements for the seat's appearance. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned problems by providing a fixing structure for the side wing cover of an automobile seat. This fixing structure not only enables the cover to be installed on the surface of the mounting cavity, but also solves the problem of pits in some covers due to lack of support, thereby improving the texture of the cover and meeting the customer's requirements for the appearance of the seat.

[0005] To achieve the above objectives, this utility model provides a fixing structure for a car seat side wing cover, including an extrusion clip and a fixing clip disposed on one side of the cover opposite to the side wing plastic frame assembly. The extrusion clip is an integral structure formed by three sides, and a fixing clip is provided at the notch of the extrusion clip. The cover is engaged in the engagement groove of the side wing plastic frame assembly through the cooperation of the extrusion clip and the fixing clip.

[0006] As a further optimization, one side of the fixing strip body is connected to a strip side arm via a first arc transition, and the other side of the fixing strip body is connected to an arc-shaped sidewall extending toward the side wing plastic frame assembly via a second arc transition. The fixing strip is provided with multiple claws in the direction toward the side wing plastic frame assembly, and the side of the fixing strip away from the claws has an outwardly extending flange.

[0007] As a further optimization, the protective panel includes a first piece and a second piece, which are joined together by sewing.

[0008] As a further optimization, the fixing strip has an avoidance groove at the seam of the facing.

[0009] As a further optimization, the faceplate is connected to the extruded strip by sewing.

[0010] As a further optimization, the protective faceplate is connected to the fixing clips via fixing pins.

[0011] Advantages and beneficial effects of this utility model

[0012] This invention optimizes and improves the extruded retaining strip. The original extruded retaining strip was a one-piece structure formed by four sides; now it is a one-piece structure formed by three sides. A fixing strip is also added to the notch of the extruded retaining strip. In this way, the snap-fit ​​grooves around the mounting cavity can be snapped into the cover using both the extruded retaining strip and the fixing strip. Because the shape of the fixing strip matches the shape below the snap-fit ​​groove, the problem of some cover surfaces being recessed downwards is successfully solved, greatly improving the texture of the cover and meeting customer requirements for the seat's appearance.

[0023] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein.

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in Figure 8. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] As shown in Figures 6 and 8, the side wing plastic frame assembly 4 is provided with a mounting cavity 41 for placing the side wing airbag. The top of the mounting cavity 41 is provided with a snap-fit ​​groove 42 around its perimeter. The snap-fit ​​groove 42 is provided with multiple snap points 43. In order to prevent the side wing airbag and the mounting cavity 41 from leaking out, a protective surface 1 is installed on the top of the mounting cavity 41. In order to prevent the protective surface 1 below the snap-fit ​​groove 42 from having a downward recess, this embodiment uses a fixing structure to install the protective surface 1 on the surface of the mounting cavity 41.

[0026] As shown in Figures 1-5, a fixing structure for a car seat side wing cover includes an extrusion strip 2 and a fixing strip 3 disposed at the bottom of the cover 1. The structure of the cover 1, as shown in Figure 1, includes a first cut piece 11 and a second cut piece 12, which are sewn together to form the cover 1. The left, top, and right sides of the bottom of the cover 1 are sewn to the extrusion strip 2. The extrusion strip 2 is an integral structure formed by three sides, and has a notch at its bottom. There is a fixing strip 3, which is connected to the bottom of the cover 1 by fixing nails 5. The perimeter of the cover 1 is engaged in the snap-fit ​​groove 42 of the side wing plastic frame assembly 4 by the joint cooperation of the extruded strip 2 and the fixing strip 3. Since the shape of the fixing strip 3 matches the shape below the snap-fit ​​groove 42, it avoids the problem of the strip below the cover 1 not matching the bottom of the snap-fit ​​groove 42, which would result in a lack of support for the cover and cause the cover to sink downward. This greatly improves the texture of the cover and meets the customer's requirements for the appearance of the seat.

[0027] As shown in Figure 5, the left side of the clip body 31 of the fixing clip 3 is connected to an upwardly extending clip side arm 33 via a first arc-shaped transition 32. The right side of the clip body 31 is connected to an arc-shaped sidewall 35 extending towards the side wing plastic frame assembly 4 via a second arc-shaped transition 34. The outer sides of the clip sidewall 33, the first arc-shaped transition 32, the clip body 31, the second arc-shaped transition 34, and the arc-shaped sidewall 35 are integrally connected with an outwardly extending flange 37. The clip body 31 has an inwardly concave position relative to the seam allowance of the first cut piece 11 and the second cut piece 12. The recessed relief groove 38 can avoid the position of the seam of the cover 1, so as to prevent the seam of the cover 1 from bulging after the cover 1 is connected to the fixing strip 3. The strip body 31 has two claws 36 on the side away from the flange 37, and the strip sidewall 33 has one claw 36 on the side away from the flange 37. The fixing strip 3 is engaged with the locking point 43 in the locking groove 42 through the three claws 36. The flange 37 is used to cover the gap at the top of the locking groove 42 after engagement and to support the cover 1 on top of it.

[0028] The first arc-shaped transition 32 in the fixing strip 3 matches the arc-shaped transition section B below the snap-fit ​​groove 42, solving the problem that the transition below the existing extruded strip is a right-angle transition, which results in a lack of support for the protective surface 1 when snapping with the arc-shaped transition section B below the snap-fit ​​groove 42, causing the protective surface 1 to sink downward. Simultaneously, the depths of the snap-fit ​​grooves 42 around the mounting cavity 41 are different, with the depth at point C below the snap-fit ​​groove 42 being slightly deeper. Therefore, when the existing extruded strip is snapped into the snap-fit ​​groove 42, there is still a distance between the lower extruded strip and the bottom of the snap-fit ​​groove 42, resulting in a lack of support for the protective surface at this location, thus causing the protective surface 1 to sink downward. In this embodiment, a second arc-shaped transition 34 connects to an arc-shaped sidewall 35 extending towards the snap-fit ​​groove 42 on the right side of the strip body 31, thus filling the gap at point C below the snap-fit ​​groove 42 and preventing the protective surface 1 from sinking downward.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
