The invention discloses a manual turnover type seat headrest which comprises a headrest rod and a headrest framework which is installed at the upper end of the headrest rod in a pivoted mode and is of a hollow structure, a locking structure is fixedly installed on the headrest rod, and a locking groove is formed in the locking structure; the headrest framework is internally provided with a locking piece which is installed in a rotatable mode, and the locking piece is provided with a locking head matched with the locking groove; an elastic retaining piece used for enabling the locking head to be retained in the locking groove is arranged in the headrest framework, the headrest is provided with at least one group of unlocking assemblies, and the unlocking assemblies can control the locking piece to overcome the retaining force of the elastic retaining piece and rotate to enable the locking head to retreat from the locking groove, so that the headrest framework can rotate around the headrest rod. Linkage unlocking turnover of the headrest framework is achieved through a relatively simpler and more compact linkage structure, the structural reliability and stability are improved, meanwhile, the production cost and installation difficulty are reduced, various unlocking assemblies are matched, the multi-posture unlocking requirement is met, and the experience feeling of drivers and passengers is improved.
本发明公开了一种手动翻转式座椅头枕,包括头枕杆,以及以枢转方式安装在头枕杆的上端,中空结构的头枕骨架,头枕杆上固定安装有锁定结构,锁定结构上具有锁槽;头枕骨架内具有以可转动方式安装的锁止件,该锁止件具有与锁槽匹配的锁止头;头枕骨架内设有用于使锁止头保持在锁槽内的弹性保持件,头枕配置有至少一组解锁组件,解锁组件能够操纵锁止件克服弹性保持件的保持力,并转动以使锁止头从锁槽内退出,使头枕骨架能够绕头枕杆转动。以相对更简洁紧凑的联动结构实现头枕骨架的联动解锁翻转,提高结构可靠性和稳定性,同时降低生产成本和安装难度,并配合多种解锁组件,满足多姿态解锁需求,提高驾乘人员体验感。
