    • PROBLEM TO BE SOLVED: To provide an internal part structure allowing improvement of riding comfort of an occupant and a sure operation of an active headrest, in even a seatback incorporating the active headrest. SOLUTION: This seatback 20 incorporates the active headrest 30 for jumping out a headrest toward a rear head part side of the occupant by detecting backrest load in a lumbar spine part, of backrest load of the occupant generated when a rear collision occurs in a vehicle. In a frame 22 forming a skeleton of the seatback 20, each of a first panel member 90 formed with a through-hole 90a to correspond to the thoracic spine part of the occupant and a second panel member 92 formed with a rib 92a to correspond to the lumbar spine part of the occupant is extended. The pressure-receiving member 50 is capable of detecting the backrest load in the lumbar spine part of the occupant via the second panel member 92. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:即使是包括主动式头枕的座椅靠背,也可以提供能够改善乘员的乘坐舒适性和主动式头枕的确定操作的内部部件结构。 解决方案:该座椅靠背20包括主动头枕30,用于通过检测腰椎部分中的靠背负载,发生后部碰撞时产生的乘员的靠背负载来向座椅的后头部侧侧跳出头枕 一辆车。 在形成座椅靠背20的框架的框架22​​中,形成有与乘员的胸椎部分对应的通孔90a的第一面板构件90和形成有肋92a的第二面板构件92对应于 腰部部分的乘员延长。 受压构件50能够经由第二面板构件92检测乘员的腰部部分的靠背负荷。(C)2010,JPO&INPIT
