上部椅背枢轴系统
摘要：
一种车辆座椅总成，其包括第一和第二侧支承部，该第一和第二侧支承部限定了椅背结构，该椅背结构在竖直和斜倚位置之间可操作。一机动化的驱动总成被设置在第一和第二侧支承部之间并可操作地耦接至枢轴杆，该枢轴杆与椅背结构可旋转地耦接。一上部椅背悬挂组件被耦接至枢轴杆。当椅背结构处在竖直位置时，该上部椅背悬挂组件相对于枢轴杆自动地向后部向位置枢转，且当该椅背结构处在斜倚位置时，该上部椅背悬挂组件相对于枢轴杆自动地向前部向位置枢转。一种外周间隙被限定在上部椅背悬挂组件和椅背结构之间。
摘要（英）：

A vehicle seating assembly includes first and second side supports defining a seatback structure that is operable between upright and reclined positions. A motorized actuation assembly is disposed between the first and second side supports and is operably coupled to a pivot bar that is rotatably coupled with the seatback structure. An upper seatback suspension component is coupled to the pivot bar. The upper seatback suspension component automatically pivots relative to the pivot bar to a rearward position when the seatback structure is in the upright position and automatically pivots relative to the pivot bar to a forward position when the seatback structure is in the reclined position. An external peripheral gap is defined between the upper seatback suspension component and the seatback structure.
