Abstract

Disclosed is a reversible headrest, comprising: a headrest body (100) and a headrest inserting rod (200). The headrest body (100) is coated and hinged on a crossbar (210) of the headrest inserting rod (200). Two vertical rods (220; 230) of the headrest inserting rod (200) are inserted into a seat, and the headrest inserting rod (200) further comprises a fixed tooth (410), a torsion spring (420), a rotating tooth (450), and a restoration tension spring (430). A headrest body locking portion (411), a headrest body rotating tooth portion (412), and a headrest body flipped locking portion (413) are arranged on the fixed tooth (410). The rotating tooth (450) is provided with a rotating tooth portion (451). When the rotating tooth portion (451) cooperates with the headrest body locking portion (411) on the fixed tooth (410), the headrest body (100) is locked at an initial use position. When the rotating tooth portion (451) cooperates with the headrest body rotating tooth portion(412) on the fixed tooth (410), the headrest body (100) is in a reversible position. When the rotating tooth portion (451) cooperates with the headrest body flipped locking portion (413) on the fixed tooth, the headrest body (100) is locked at a flat position. The reversible headrest has the advantages of strong self-locking ability, few parts, simple structure and low cost.

Abstract

Disclosed is a power supply mechanism of a long-travel seat, the mechanism comprising: a wiring harness storage box (11), the wiring harness storage box (11) being provided with at least one storage space and an opening (10); a drag chain (12) bent and accommodated in the storage space, with a first end (121) being relatively fixed to the wiring harness storage box (11), and a second end (122) passing out of the opening (10) and being slidingly arranged inside a slideway of a lower slide rail (21) of the seat; and a wiring harness arranged in the drag chain (12) in a penetrating manner, with a first end passing out of a first end of a wiring harness passage and the opening (10) and being connected to a power supply body, and a second end passing out of a second end of the wiring harness passage and being connected to an upper slide rail (22) of the seat. By using a drag chain to accommodate a wiring harness inside a wiring harness storage box and inside a slideway of a lower slide rail of a seat, the wiring harness can share a slideway with an upper slide rail and moves along with the sliding of the upper slide rail; and the drag chain shuttles back and forth in the wiring harness storage box and the lower slide rail with the movement of the wiring harness, thereby satisfying a power supply requirement of a long-travel seat.
