seat back cushion

The effects of head restraint geometry, seat back cushion stiffness, recliner stiffness, impact velocity and acceleration on neck global kinematics responses are analyzed.

使用该模型，分析了头枕位置、靠背刚度分布、调角器刚度等座椅参数、以及碰撞速度和加速度对颈部整体动力学响应的影响。

Seat and back cushion is made of high density and high elasticity PU foam, covered with fire retardant cloth exteriorly.

椅座，椅背衬垫采用高密度，高弹性的聚氨脂泡绵，外面覆盖耐火布料。

Remove the seat back from the seat cushion and place it on a suitable work surface.

将座位靠背从座位垫上拆下,并将其放至适当的工作台上.

The adopted technical proposal is as cushion consists of a seat cushion and a back cushion.

采用的技术方案是:由座垫和靠垫组成.

The simulation results show that head restraint position, seat back cushion stiffness, recliner stiffness and occupant seating posture have great influence on occupant head-neck kinematics responses, neck injury risks can be reduced by proper seat design.

仿真分析结果表明，头枕位置、靠背刚度、靠背倾角调节器特性和乘员乘坐姿势对乘员头颈部的动力学响应有很大影响，通过合理的座椅设计可以显著降低颈部损伤风险。
