Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a universal L-shaped lockable headrest guide sleeve. Background Technology

[0002] Currently, most automotive seat headrest guide sleeves employ an asymmetrical design, requiring the development of separate molds for the left and right sides, resulting in high costs. Furthermore, traditional guide sleeves have complex structures and poor limiting effects, affecting the stability of the headrest's movement in the Z-axis. Therefore, a guide sleeve with a simple structure, universal applicability, and reliable limiting is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a universal L-shaped lockless headrest guide sleeve. Through internal limiting ribs and Z-direction locking point structure, it achieves multi-directional limiting of the headrest rod and fixation of the guide sleeve itself. At the same time, the guide sleeve is universal for both left and right sides, reducing cost and weight.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A universal L-shaped lockable headrest guide sleeve includes a headrest guide sleeve body, which is L-shaped and universal for both left and right sides. The headrest guide sleeve body includes a guide sleeve for connecting the headrest rod and a fixing part connected to the guide sleeve. The guide sleeve has a limiting rib inside and a Z-direction locking point structure symmetrically provided on the outer side of the guide sleeve. The Z-direction locking point structure is used to lock into the metal sleeve of the backrest to restrict the movement of the guide sleeve in the Z direction.

[0006] Furthermore, the limiting rib includes multiple ribs arranged along the insertion direction of the headrest rod to limit the X and Y direction movement of the headrest rod.

[0007] Furthermore, the headrest guide sleeve body is made of PP+EPDM-T20 material.

[0008] Furthermore, the Z-axis locking point structure is an elastic buckle that can be locked and fixed to the inner wall of the backrest metal sleeve.

[0009] Furthermore, it also includes a cover that engages with the fixing part.

[0010] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:

[0011] This utility model discloses a universal L-shaped lockless headrest guide sleeve. It achieves stable guidance of the headrest rod through internal limiting ribs, and the Z-direction locking point structure ensures the fixation of the guide sleeve. The universal design reduces the number of molds and lowers costs. It solves the technical barrier of inconsistent guide sleeves in traditional models, and the part structure is simpler. It is suitable for stable Z-direction movement of electric headrests. In addition, the headrest guide sleeve body is made of PP+EPDM-T20 material, which has both toughness and lightweight characteristics. Attached Figure Description
