Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a headrest cavity connection and tensioning structure. Background Technology

[0002] End customers have increasingly higher requirements for the appearance of seats. To accurately respond to this demand, it is necessary to optimize the fixing method of the headrest cavity. In the past, cloth strips were used for fixing, which not only relied on manual operation, but also had obvious instability in the fixing effect. Therefore, it is necessary to develop a headrest cavity connection and tensioning structure for the headrest cavity of the seat back. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a headrest cavity connection tensioning structure, which can improve the aesthetics while ensuring the headrest cavity is tensioned, so as to overcome the shortcomings of the prior art.

[0004] This utility model provides a headrest cavity connection and tensioning structure, including: a headrest cavity cover assembly covering a foam assembly. The improvement is that the headrest cavity cover assembly includes: a cover assembly and a headrest cavity tensioning structure sewn inside the cover assembly. The headrest cavity tensioning structure includes: a headrest cavity side panel composed of a middle cut piece and two guide cut pieces on both sides, a support piece, and a bristle strip. The headrest cavity side panel and the support piece are sewn together to form a headrest cavity. The bristle strip consists of a bristle strip hook surface fixed to the center position of the headrest connection of the foam assembly and a bristle strip adhesive surface sewn inside the headrest cavity. The headrest cavity is tensioned by bonding the bristle strip adhesive surface to the bristle hook surface of the foam assembly.

[0005] As a preferred embodiment of this utility model, the foam assembly is provided with a stepped through groove at the headrest mounting position, and the hook surface of the bristle strip is fixed in the stepped through groove.

[0006] As a preferred embodiment of this utility model, the center of the face shield assembly is provided with a central hole that has the same shape as the headrest cavity, and the upper edge of the headrest cavity, which is composed of the side wall of the headrest cavity and the support piece, is sewn to the periphery of the central hole.

[0007] The beneficial effects of this utility model are as follows: This utility model embodies the mutual compensation of the protective cover and foam, forming a stable and reliable connection structure. It changes the original cover structure, forming a completely new cover connection and fixing structure, and through the addition of a headrest cavity tensioning structure combined with barbed strips, a new and reasonable fixing method is formed. This connection method, while meeting the user's aesthetic requirements, has significant reference value for seats in other vehicle models. Attached Figure Description

[0018] See Figure 1-9 As shown, this embodiment provides a headrest cavity connection tensioning structure, including: a headrest cavity cover assembly 2 covering a foam assembly 1. The headrest cavity cover assembly 2 includes: a cover assembly 201 and a headrest cavity tensioning structure sewn inside the cover assembly 201. The headrest cavity tensioning structure includes: a headrest cavity side panel 204 composed of a middle cut piece 202 and two guide cut pieces 203 on both sides, a support piece 205, and a bristle strip 206. The headrest cavity side panel 204 and the support piece 207 are sewn together to form a headrest cavity 208. The bristle strip 206 consists of a bristle hook surface fixed to the headrest connection center position of the foam assembly 1 and a bristle adhesive surface sewn inside the headrest cavity 208. The headrest cavity 208 is bonded and tensioned to the bristle hook surface of the foam assembly 1 through the bristle adhesive surface. The foam assembly 1 has a stepped through groove 101 at the headrest mounting position, and the hook face of the bristle strip is fixed in the stepped through groove 101. The faceplate assembly 201 has a central hole with the same shape as the headrest cavity, and the upper edge of the headrest cavity 208, which is composed of the headrest cavity side wall 204 and the support piece 205, is sewn to the perimeter of the central hole.

[0019] Working principle: The middle cut piece 202 and guide cut piece 203 of the headrest cavity tensioning structure are both equipped with positioning notches. The headrest cavity side wall 204 is pre-sewn according to the position of the notches. The headrest cavity side wall 204 and the support piece 207 are sewn together through the positioning notches on the support piece 207 to form the headrest cavity 208. The bristle strip 206 is sewn onto the headrest cavity 208 to form the headrest cavity tensioning structure. During assembly, the headrest cavity faceplate assembly 2 is first installed onto the foam assembly 1, and then the adhesive surface of the bristle strip 206 of the headrest cavity is aligned with the position of the bristle strip hook surface of the foam assembly 1 to complete the tensioning and positioning.

[0020] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
