1.2 座椅布置的目的
保证驾驶员、乘员处于舒适的驾驶和乘坐姿势的状态，并 实现驾驶员与操纵机构的相对位置、乘员的一些功能操作。
2 座椅布置
2.1 座椅布置输入、周边数据以及相关的法规文件收集 研究 布置输入
了解整车配置、座椅的配置，以及将来销售区域的分布，从而 来确认所需遵循的法规条例以及相关保险行业要求； 了解座椅的功能要求，结合相应的市场，初步制定座椅的VTS； 座椅布置图、CAS以及相关边界数据，如下面图所示的数据； 参考座椅的相关数据以及骨架，用于座椅的布置，同时尽量考 虑座椅骨架的沿用； 竞争车型以及座椅的分析比较，包括座椅的功能，造型等等；

Actions
Has a Target Seat been identified (Benchmark)? Has data been collected to characterize the Target Seat? - Contour Data (Surface STO)? - OSCAR (SAE J826) Occupant Packaging / Penetration? - Stiffness / Pressure Map / Transmissibility? - Foam Properties (Firmness, Hysteresis, Thickness, Components)? - Cushion Suspension (Type / Deflection)? - Lumbar Mechanism, Actuator / Seatback Suspension Type? - Trim Properties (Lamination Thickness, Tiedown Locations)?

OSCAR Packaging
Has the Target Market Segment been established? Has the Target Consumer been identified by the Customer? Is the correct CATIA V5 OSCAR used in the CAD Model? (Hpt-Knee = 456, Knee-Ankle = 459.1, HptShol = 563) Is the seat position represented by OSCAR understood? (Full Rear, Full Down, etc.) Is the H-point to Heel point relationship & Heelplate Angle identified? Are the correct Torso, Hip, Thigh, Knee, and Foot Angles identified? Is there an H-point Travel window to identify adjustment range (track angle/travel, vertical travel)? Is the STO symmetrical about the occupant centerline? Is the Overall Width > 525 mm at Sections C200 and B100? Is the Lumbar Apex located at recommended location? Is the Thigh Exit located at recommended location? Are the Penetrations at Sections C100 and C200 the recommended depth? Has the Comfort Crosscar Geometry Tool been used to assess/generate bolster shape? Is the 10 deg. Gap at Section C0 the recommended distance? Are the 15 deg. and 20 deg. Gaps at Section B300 the recommended distances? Do Dual Firmness zones avoid manikin contact on the cushion? Do Dual Firmness zones avoid manikin contact on the seatback? Are rigid components properly located away from high pressure areas (wires)? Has the need for structural or wire support to maintain bolster feasibility been assessed? Has the H-point FEA tool been run to understand foam properties & STO feasibility? Have the Trim Cover Type (Open, Envelope) and Lamination Thicknesses been established? Are Horizontal Tiedowns located outside High Penetration areas (Beneath H-point, Near Lumbar Apex)?
2.2 座椅布置
座椅，座位汽车内饰的重要组成不分，他对 于乘客的舒适性以及安全性，起到及其重要的作 用。而在座椅的布置的同时，同样需要考虑到其 他与之相关件的布置以及内在的校核。 2.2.1 座椅法规校核 座椅法规校核主要包括：内部突出物校核，头枕校核 内部突出物校核： 在ECE R21 和 GB11552 中，明确内部突出 物的要求，对于座椅而言，主要包括三区域 的校核：
