The invention provides a rotary seat mechanism, a sliding rail mechanism is fixedly connected with a vehicle body, a connecting frame is connected between the sliding rail mechanism and a rotary disc,a supporting frame is fixedly connected between the rotary disc and a seat framework, and the sliding rail mechanism is hinged to the rotary disc through three hinge points formed by a connecting rod, a first connecting support and a second connecting support; the sliding rail mechanism is directly hinged to the rotary disc through a fourth hinge point, the two ends of the connecting rod are hinged to the sliding rail mechanism and the rotary disc respectively, the first connecting support is provided with a first curve open groove allowing a hinge piece forming a second hinge point to slide,and the second connecting support is provided with a second curve open groove allowing a hinge piece forming a third hinge point to slide. The rotary seat mechanism further comprises a main safety belt support fixedly connected with the sliding rail mechanism, and the rotary disc is provided with an inwards-concave part used for avoiding the main safety belt support. According to the rotary seatmechanism, the main safety belt support is installed on the sliding rail mechanism, the requirement for the strength of the rotary disc is avoided, and the design difficulty of the rotary seat mechanism is greatly reduced.
本发明涉及一种旋转座椅机构,滑轨机构固定连接在车身上,连接架连接在滑轨机构和转盘之间,支撑架固定连接在转盘和座椅骨架之间,滑轨机构与转盘通过连杆、第一连接支架和第二连接支架形成的三个铰接点铰接,滑轨机构与转盘通过第四铰接点直接铰接,连杆的两端分别铰接于滑轨机构和转盘,第一连接支架具有供形成第二铰接点的铰接件滑动的第一曲线开槽,第二连接支架具有供形成第三铰接点的铰接件滑动的第二曲线开槽,旋转座椅机构还包括固定连接在滑轨机构上的主安全带支架,转盘具有用于避让主安全带支架的向内凹进部分。根据本发明的旋转座椅机构,主安全带支架安装在滑轨机构上,避免了对转盘的强度要求,大幅降低旋转座椅机构的设计难度。
